Behavior modification comprises those procedures aimed at changing behavior patterns. Another term is behavior therapy. It has been promoted since the 1970s by the school of behaviorism, especially by John Watson and B.F. Skinner. They argued that the usual approaches of psychology with their emphasis on introspection are not working. Psychology should be redefined as a natural science since its goal is the prediction and control of human behavior.

Expression of sexually dimorphic behaviors critical for reproduction depends on the organizational actions of steroid hormones on the developing brain. We offer the new hypothesis that transcriptional activities in brain regions executing these sexually dimorphic behaviors are modulated by estrogen‐induced modifications of histone proteins. Specifically, in preoptic nerve cells responsible for facilitating male sexual behavior in rodents, gene expression is fostered by increased histone acetylation and reduced methylation (Me), and, that the opposite set of histone modifications will be found (...) in females. Conversely, in ventromedial hypothalamic neurons that are responsible for coordinating female sexual behavior, transcriptional activities in genetic females are fostered by increased histone acetylation and reduced Me, and, further, that the opposite set of histone modifications will be found in males. Thus, these epigenetic events will guarantee that effects of sex hormone exposure during the neonatal critical period will be translated into lasting sex differences in adult reproductive behaviors.

I argue that the use of heritable modifications for psychology, personality, and behavior should be limited to the reversal or prevention of relatively unambiguous instances of pathology or likely harm (e.g. sociopathy). Most of the likely modifications of psychological personality would not be of this nature, however, and parents therefore should not have the freedom to make such modifications to future children. I argue by examining the viewpoints of both the individual and society. For individuals, modifications would interfere with (...) their capacity for self-determination in a way that undermines the very concept of self-determination. I argue that modification of psychology and personality is unlike present parenting in morally significant ways. For society, modification offers a medium for power to manipulate the makeup of persons and populations, possibly causing biological harm to the species and altering our conceptions of social responsibility.

This paper offers a new semantic theory of existentials (sentences of the form There be NP pivot XP coda ) in which pivots are (second order) predicates and codas are modifiers. The theory retains the analysis of pivots as denoting generalized quantifiers (Barwise and Cooper 1981; Keenan 1987), but departs from previous analyses in analyzing codas as contextual modifiers on a par with temporal/locative frame adverbials. Existing analyses universally assume that pivots are arguments of some predicate, and that codas are (...) main or secondary predicates. It is shown that these analyses cannot account for the behavior of codas with quantifiers and for the interaction of multiple codas, both of which receive a simple treatment on the proposed theory. The assimilation of codas to frame adverbials explains several semantic properties which have not been analyzed in the semantic literature, and that distinguish existentials from their copular counterparts. Furthermore, it highlights important properties of the semantics of modification and its relation to predication. (shrink)

To decode the function and molecular recognition of several recently discovered cytosine derivatives in the human genome – 5-hydroxymethylcytosine, 5-formylcytosine, and 5-carboxylcytosine – a detailed understanding of their effects on the structural, chemical, and biophysical properties of DNA is essential. Here, we review recent literature in this area, with particular emphasis on features that have been proposed to enable the specific recognition of modified cytosine bases by DNA-binding proteins. These include electronic factors, modulation of base-pair stability, flexibility, and radical changes (...) in duplex conformation. We explore these proposals and assess whether or not they are supported by current biophysical data. This analysis is focused primarily on the properties of epigenetically modified DNA itself, which provides a basis for discussion of the mechanisms of recognition by different proteins. 5-hydroxymethylcytosine, 5-formylcytosine, and 5-carboxylcytosine have recently been discovered in mammalian DNA and appear to have essential regulatory roles. Here, we summarize recent investigations into their effects on the structural, chemical, and biophysical properties of DNA, an understanding of which is essential to decoding their behavior in the genome.

In light of the recent focus in bioethics on questions of deliberate moral enhancement through the use of psychoactive drugs, Levy et al. (2014) argue that the more pressing issue may be the incidental effect that prescription drugs could already be having on moral agency. Although concerns have focused on the possibility of altering moral psychology through direct effects on brain function, the authors point out that this may already be a reality, albeit an unintentional one. They conclude from their (...) survey of prescription drugs already in use, that we should urgently investigate the ways they may be “influencing the shape of our societies” (2014, 123). The question of how we ought to respond to this possibility, I believe, must be considered in the broader context of existing attitudes and policy in response to substances with similar effects; and the relative significance of these drug effects compared with other factors, in particular social factors that shape society through their developmental influence on moral psychology. First, it is important to consider the drugs described by the authors alongside widely used drugs with known, comparable effects. For example, alcohol has profound effects on features of cognition that seem relevant to moral agency, in altering risk assessment and increasing aggression (Bushman and Cooper 1990; George et al. 2005). Its impairing of inhibitory control arguably undermines the reflective processes that are often considered central to moral agency (Craigie 2011; Field et al. 2010). However, by and large the current policy adopted in liberal democratic societies is to educate people about these dangers but leave it up to adults to choose whether they use alcohol. Exceptions to this position are grounded in reasons of public protection, for example, in the case of blood alcohol limits for drivers in order to protect people against injury or death as a result of drunk driving. Restrictions are also sometimes placed on inebriation in the context of particular public roles, for example, serving on a jury, although the issue remains controversial (Law Reform Commission 2010, s. 8.21, 8.26, 8.27). This approach to alcohol regulation offers an established model for responding to the kinds of drugs in question. Broadly, it suggests that concerns about the effect of a drug on moral agency are only considered serious enough to warrant restricting its use when this puts others at risk of serious harms, or when a person is fulfilling a public role where sound decision making is of great importance (e.g., in maintaining trust in institutions such as the criminal justice system). Although at first it may be an alarming thought that pharmaceuticals [End Page 127] could be influencing individual moral psychology, the example of alcohol suggests that this this is a familiar experience, and something for which states already have a policy framework. Caffeine is another commonly used drug with psychoactive properties that seem likely to affect moral agency. Along with potentially morally relevant effects on attention and aggression (Einöther and Giesbrecht 2013; Kuhns et al. 2010), research suggests a connection between cortisol—a hormone that is elevated by caffeine—and the processing of social cues relating to threat (Montoya et al. 2012; Putman et al. 2007). There are little in the way of restrictions on the use of caffeine. Nonetheless, one might be concerned about the possible effects of caffeine on moral agency and society, particularly if the effects are less obvious than in the case of alcohol (Kuhns et al. 2010). The same concern might apply to the pharmaceuticals in question. Perhaps there is a need to investigate these effects on thought and behavior because they are not easy to detect. The greater danger might be in the fact that people do not recognize how these drugs change their appraisals and decisions, rather than in the effects themselves. It seems a reasonable suggestion that if a drug has significant enough effects on interpersonal relationships, then this information should be made available as a part of an informed consent procedure.

B. F. Skinner argues in Beyond Freedom and Dignity (New York 1971) that only his theory of man is compatible with a ‘scientific’ approach to human behavior. I argue that Skinner's entirely open‐ended view of man is inadequate for his own purposes in that it leaves no room for the claim that certain value judgments are universally valid, something I argue Skinner is committed to despite an explicit avowal in one place of cultural relativism. I then go on to (...) show that a modification of Skinner's theory of man which builds on Spinoza's notion of conatus would provide one with a theory‐based rationale for universally valid judgments without involving one in a ‘non‐scientific’ approach to human behavior. Specifically, I argue that such a Spinozistic modification would provide one with a theory‐based guarantee that man will not evolve in such a way that a truly scientific observer would deem a totalitarian state good.

Membranous organelles allow sub‐compartmentalization of biological processes. However, additional subcellular structures create dynamic reaction spaces without the need for membranes. Such membrane‐less organelles (MLOs) are physiologically relevant and impact development, gene expression regulation, and cellular stress responses. The phenomenon resulting in the formation of MLOs is called liquid–liquid phase separation (LLPS), and is primarily governed by the interactions of multi‐domain proteins or proteins harboring intrinsically disordered regions as well as RNA‐binding domains. Although the presence of RNAs affects the formation and (...) dissolution of MLOs, it remains unclear how the properties of RNAs exactly contribute to these effects. Here, the authors review this emerging field, and explore how particular RNA properties can affect LLPS and the behavior of MLOs. It is suggested that post‐transcriptional RNA modification systems could be contributors for dynamically modulating the assembly and dissolution of MLOs. (shrink)

Response to commentary. We are grateful to Crockett and Craigie for their interesting remarks on our paper. We accept Crockett’s claim that there is a need for caution in drawing inferences about patient groups from work on healthy volunteers in the laboratory. However, we believe that the evidence we cited established a strong presumption that many of the patients who are routinely taking a medication, including many people properly prescribed the medication for a medical condition, have morally significant aspects of (...) their cognition and behavior modified in a way that is unintended and may sometimes be unwelcome. Crockett notes that in some cases the effects of long-term drug use may differ, sometimes markedly, from the effects of short-term use. However, if acute use of a drug affects a neural system involved in mediating moral cognition or behavior, this nevertheless provides some evidence that chronic use of the drug may affect that same system and thus have morally significant effects. It is also plausible, in some cases, that an acute moral effect would give rise to a chronic moral effect via cognitive mechanisms. ... (shrink)

Open peer commentary on the article “Perception-Action Mutuality Obviates Mental Construction” by Martin Flament Fultot, Lin Nie & Claudia Carello. Upshot: In my view, the clash between ecological psychology, enactivism, and constructivism in general has more to do with irreconcilable metaphysical and theoretical incommensurabilities than disagreements about specific mechanisms or processes of perception. Even with mutual enabling of action and perception, some internal process of self-modification is still needed if novel behavior is to be adequately explained.

It has been shown that the orbits of motion for a wide class of non-relativistic Hamiltonian systems can be described as geodesic flows on a manifold and an associated dual by means of a conformal map. This method can be applied to a four dimensional manifold of orbits in spacetime associated with a relativistic system. We show that a relativistic Hamiltonian which generates Einstein geodesics, with the addition of a world scalar field, can be put into correspondence in this way (...) with another Hamiltonian with conformally modified metric. Such a construction could account for part of the requirements of Bekenstein for achieving the MOND theory of Milgrom in the post-Newtonian limit. The constraints on the MOND theory imposed by the galactic rotation curves, through this correspondence, would then imply constraints on the structure of the world scalar field. We then use the fact that a Hamiltonian with vector gauge fields results, through such a conformal map, in a Kaluza-Klein type theory, and indicate how the TeVeS structure of Bekenstein and Saunders can be put into this framework. We exhibit a class of infinitesimal gauge transformations on the gauge fields ${\mathcal{U}}_{\mu}(x)$ which preserve the Bekenstein-Sanders condition ${\mathcal{U}}_{\mu}{\mathcal{U}}^{\mu}=-1$ . The underlying quantum structure giving rise to these gauge fields is a Hilbert bundle, and the gauge transformations induce a non-commutative behavior to the fields, i.e. they become of Yang-Mills type. Working in the infinitesimal gauge neighborhood of the initial Abelian theory we show that in the Abelian limit the Yang-Mills field equations provide residual nonlinear terms which may avoid the caustic singularity found by Contaldi et al.

Technology pertaining to genetically modified foods has created an abundance of food and various methods to protect new products and enhance productivity. However, many scientists, economists, and humanitarians have been critical of the application of these discoveries. They are apprehensive about a profit-driven mentality that, to them, seems to propel the innovators rather than a poverty-elimination mentality that should be behind such innovations. The objectives should be to afford the most benefit to those in need and to prevent hunger around (...) the world. Another major concern is the safety of genetically modified food. Muslims, as well as those in other religious communities, have been reactive rather than proactive. Muslims must connect scientific knowledge and ethical behavior based on faith. In Islam, there is no divide between the two. God has commanded us to seek knowledge and make discoveries to better our lives and our environment. We are trustees of this world and everything in it. The poor, the sick, and the wayfarers have a right to be fed and cared for. God reminds Muslims continuously that the earth and all the heavens belong to God; therefore, no one should feel hunger, no one should suffer or be prevented from sharing this bounty. (shrink)

Some philosophers of religion claim that one reason God permits suffering is to make people dissatisfied with their lives so they will turn to him. That theodicy is inadequate because 1) that strategy of behavior modification constitutes punishment (in the psychologists’ sense), and 2) punishment is not the most effective strategy of behavior modification. Since God can be expected to use the most effective strategy available to him, such a theodicy is inadequate.

Understanding how transcription factor (TF) binding is related to gene regulation is a moving target. We recently uncovered genome‐wide evidence for a “Hit‐and‐Run” model of transcription. In this model, a master TF “hits” a target promoter to initiate a rapid response to a signal. As the “hit” is transient, the model invokes recruitment of partner TFs to sustain transcription over time. Following the “run”, the master TF “hits” other targets to propagate the response genome‐wide. As such, a TF may act (...) as a “catalyst” to mount a broad and acute response in cells that first sense the signal, while the recruited TF partners promote long‐term adaptive behavior in the whole organism. This “Hit‐and‐Run” model likely has broad relevance, as TF perturbation studies across eukaryotes show small overlaps between TF‐regulated and TF‐bound genes, implicating transient TF‐target binding. Here, we explore this “Hit‐and‐Run” model to suggest molecular mechanisms and its biological relevance. (shrink)

ObjectivesThis pilot study sought to develop and evaluate a novel online group-based intervention to help breast cancer survivors make healthy lifestyle changes intended to yield not only beneficial physical outcomes but also greater behavioral, and psychosocial well-being.MethodsAn exploratory single-arm, mixed-method triangulation design was employed to evaluate the feasibility and preliminary effectiveness of the HLM-ABC intervention for overweight BCSs. Fourteen women participated in the 10-week intervention and completed quantitative measures of the above-mentioned outcomes at baseline, post-treatment, 6-month, and 12-month follow-up time (...) points. Qualitative data were obtained post-treatment via semi-structured interviews and a treatment satisfaction questionnaire.ResultsParticipants lost an average of 2.83% of their baseline weight by 1-year follow-up, equal to a small effect size. Despite achieving only modest weight loss, participants achieved meaningful gains in the form of increased physical activity, discovery of gratifying movement, more intuitive eating habits, greater bodily and emotional awareness, and positive shifts in beliefs about being able to make healthy choices regarding food and physical activity. Furthermore, they demonstrated a slight improvement in body image and described feeling more self-compassionate, empowered, and acknowledging of variables beyond control that can present barriers to change.ConclusionAfter completing a 10-week online program, participants achieved meaningful and lasting changes on a number of healthful indicators, even when this did not correspond with a significant reduction in weight. Findings highlight the complex, multifaceted nature of “health” and lend support for promotion of healthier lifestyle following cancer treatment that encompasses not only physical weight, but also behavior, psychosocial well-being, and circumstances such as life-preserving hormonal treatments.

Neurons of organisms with complex and flexible behavior, especially humans, must precisely control protein localization and activity to support higher brain functions such as learning and memory. In contrast, simpler organisms generally have simpler individual neurons, less complex nervous systems and display more limited behaviors. Strikingly, however, many key neuronal proteins are conserved between organisms that have very different degrees of behavioral complexity. Here we discuss a possible mechanism by which conserved neuronal proteins acquired new attributes that were crucial (...) in the evolution of complexity of nervous system structure and function. Specifically, we hypothesize that vertebrate‐specific post‐translational palmitoylation sites and PDZ‐binding protein‐protein interaction motifs act as gain‐of‐function mutations, increasing the regulatory potential of conserved proteins without affecting their core functions. We further hypothesize that the additional regulation of neurotransmitter receptors and other membrane proteins made possible by these sites and motifs is critical for the function of complex nervous systems.

This book reviews how people and animals learn and how their behaviors are later changed as a result of this learning. Nearly all of our behaviors are influenced by prior learning experiences in some way. This book describes some of the most important principles, theories, controversies, and experiments that pertain to learning and behavior that are applicable to many different species and many different learning situations. Many real-world examples and analogies make the concepts and theories more concrete and relevant (...) to the students. In addition, most of the chapters include sections that describe how the theories and principles have been used in the applied field of behavior modification. Each chapter in the seventh edition was updated with new studies and new references that reflect recent developments in the field. The book includes a number of learning aids for students, including a list of learning objectives at the beginning of each chapter, practices quizzes and review questions, and a glossary for all important terms. _Learning & Behavior _covers topics such as classical and operant conditioning, reinforcement schedules, avoidance and punishment, stimulus control, comparative cognition, observational learning, motor skill learning, and choice. Both the classic studies and the most recent developments and trends in the field are explored. Although the behavioral approach is emphasized, many cognitive theories are covered as well along with a chapter on comparative cognition. Upon completing this book readers will be able to:understand the field of learning and discuss real-world applications of learning principles. (shrink)

Humanism and radical behaviorism are two of today's most anxiety-provoking systems of thought. While they have challenged some of society's most comforting notions, each has long been viewed as opposed to the other's practice of psychology. In this adversarial climate of contemporary psychology, Bobby Newman's compelling assessment in The Reluctant Alliance effectively tears down many of the ideological walls separating these two powerful schools of thought. He carefully researches the positions of both camps to dispel the myths that behaviorists are (...) "manipulators" and humanistic psychologists are "armchair philosophers". After examining both systems, Newman outlines their shared philosophical and historical roots and explores such questions as: How should psychotherapy be conducted? How is moral behavior created and maintained? Is behaviorism inherently unethical? What forms of education are most effective at imparting information and improving self-concepts? As Newman points out, "It is my intention to demonstrate that the differences between the two systems are not as great as they are made to seem. More importantly, I will suggest that each system contains flaws that can be corrected by combining elements of the other". After reading The Reluctant Alliance humanists will come to appreciate that behaviorism is not destructive determinism, and behaviorists will learn that much of what they hold to be true is a natural outgrowth of humanistic thought.

There is a growing body of evidence that points to an important role for modification of lifestyle factors and promotion of health-related quality of life in the secondary prevention of disease progression in multiple sclerosis ( D’Hooghe et al., 2010 ; Weiland et al., 2014 ; Hadgkiss et al., 2015 ). As a clinical psychologist diagnosed with multiple sclerosis in 2012 I have gained a unique insight into ways in which people living with MS and clinicians can usefully integrate (...) evidence-based lifestyle modifications that enhance self-efficacy and self-management to improve wider psychological and physical health. The framework presented here enables clinicians to engage in salutogenic health promotion by placing value upon the importance of healthy, evidence-based behavior change.

PCOS in PubMed, Cochrane library, Embase, ClinicalTrials.gov, CNKI, and WANFANG DATA were searched for up to 19 November 2020. A random-effects model was used to perform a meta-analysis.ResultsEight trials regarding CBT compared with lifestyle modification and routine treatments were included. No differences in depression, body mass index, or overall life quality were evident between CBT and control groups; however, anxiety and quality of life in hirsutism were significantly improved. For secondary outcomes, both patient compliance and pregnancy rate were improved, but no significant change in pregnancy loss rate was identified.ConclusionCBT exhibited obvious advantages in the alleviation of anxiety, improvement of quality of life in hirsutism, and increase of compliance and pregnancy rate in patients with PCOS. Larger and higher-quality randomized controlled trials are needed to clarify the role of CBT in PCOS.Systematic review registration[https://www.crd.york.ac.uk/PROSPERO/], identifier [CRD42021225856].

Behavioral ecology, based in the theory of natural selection, predicts that certain behaviors are likely to differ consistently between the sexes in humans as well as other species: aggression, resource striving, information content of sexual signalling. These differences, though of course open to modification by cultural practice, arise because male and female humans, like males and females of other mammal species, typically optimize their reproductive lifetimes through different behaviors: males specializing in mating effort (which has a high fixed cost, (...) and is not offspring-specific), and females in parental effort (which has more linear reproductive returns, and is offspring-specific). The resulting patterns are reviewed. (shrink)

Many human cultural traits become increasingly beneficial as they are repeatedly transmitted, thanks to an accumulation of modifications made by successive generations. But how do later generations typically avoid modifications which revert traits to less beneficial forms already sampled and rejected by earlier generations? And how can later generations do so without direct exposure to their predecessors' behavior? One possibility is that learners are sensitive to cues of non‐random production in others' behavior, and that particular variants (e.g., those (...) containing structural regularities unlikely to occur spontaneously) have been produced deliberately and with some effort. If this non‐random behavior is attributed to an informed strategy, then the learner may infer that apparent avoidance of certain possibilities indicates that these have already been sampled and rejected. This could potentially prevent performance plateaus resulting from learners modifying inherited behaviors randomly. We test this hypothesis in four experiments in which participants, either individually or in interacting dyads, attempt to locate rewards in a search grid, guided by partial information about another individual's experience of the task. We find that in some contexts, valid inferences about another's behavior can be made from partial information, and these inferences can be used in a way which facilitates trait adaptation. However, the benefit of these inferences appears to be limited, and in many contexts—including some which have the potential to make inferring the experience of another individual easier—there appears to be no benefit at all. We suggest that inferring previous behavior from partial social information plays a minimal role in the adaptation of cultural traits. (shrink)

We investigate how a group of players might cooperate with each other within the setting of a non-cooperative game. We pursue two notions of partial cooperative equilibria that follow a modification of Nash’s best response rationality rather than a core-like approach. Partial cooperative Nash equilibrium treats non-cooperative players and the coalition of cooperators symmetrically, while the notion of partial cooperative leadership equilibrium assumes that the group of cooperators has a first-mover advantage. We prove existence theorems for both types of (...) equilibria. We look at three well-known applications under partial cooperation. In a game of voluntary provision of a public good we show that our two new equilibrium notions of partial cooperation coincide. In a modified Cournot oligopoly, we identify multiple equilibria of each type and show that a non-cooperator may have a higher payoff than a cooperator. In contrast, under partial cooperation in a symmetric Salop City game, a cooperator enjoys a higher return. (shrink)

Psychopathy is a disorder involving personality and behavioral features associated with a high rate of violent aggression and recidivism. This paper explores potential psychopharmacological therapies to modulate dysfunctional neural pathways in psychopaths and reduce the incidence of their harmful behavior, as well as the ethical and legal implications of offering these therapies as an alternative to incarceration. It also considers whether forced psychopharmacological intervention in adults and children with psychopathic traits manifesting in violent behavior can be justified. More (...) generally, the paper addresses the question of how to weigh the psychopath’s presumptive right to non-interference in his brain and mind against the public interest in avoiding harm.

There has been a proliferation of posted behavior signs in the past five years, which are now ubiquitous in both inpatient and outpatient settings and across pediatric, adult, and allied health practices. Named as notices for “Patient and Visitors,” these behavior signs identify a range of conduct from clinical noncompliance, use of profanity, and raised voices to acts or threats of physical violence. While these signs offer a tangible signal from the institution’s leadership to their staff that disruptive (...) behavior is unacceptable, there is no empirical evidence that behavior signs are effective in reducing workplace violence or verbal attacks. Aside from the problem of efficacy, posted behavior signs are ethically troubling for the way they treat patients and families and for the impact they can have on them. We identify four distinct ethical concerns with posted behavior signs that we believe require either removal or substantial modification of these signs. (shrink)

In this paper we show how recent concepts from Dynamic Logic, and in particular from Dynamic Epistemic logic, can be used to model and interpret quantum behavior. Our main thesis is that all the non-classical properties of quantum systems are explainable in terms of the non-classical flow of quantum information. We give a logical analysis of quantum measurements (formalized using modal operators) as triggers for quantum information flow, and we compare them with other logical operators previously used to model (...) various forms of classical information flow: the “test” operator from Dynamic Logic, the “announcement” operator from Dynamic Epistemic Logic and the “revision” operator from Belief Revision theory. The main points stressed in our investigation are the following: (1) The perspective and the techniques of “logical dynamics” are useful for understanding quantum information flow. (2) Quantum mechanics does not require any modification of the classical laws of “static” propositional logic, but only a non-classical dynamics of information. (3) The main such non-classical feature is that, in a quantum world, all information-gathering actions have some ontic side-effects. (4) This ontic impact can affect in its turn the flow of information, leading to non-classical epistemic side-effects (e.g. a type of non-monotonicity) and to states of “objectively imperfect information”. (5) Moreover, the ontic impact is non-local: an information-gathering action on one part of a quantum system can have ontic side-effects on other, far-away parts of the system. (shrink)

In this paper, we introduce an ecological account of communication according to which acts of communication are active inferences achieved by affecting the behavior of a target organism via the modification of its field of affordances. Constraining a target organism’s behavior constitutes a mechanism of socially extended active inference, allowing organisms to proactively regulate their inner states through the behavior of other organisms. In this general conception of communication, the type of cooperative communication characteristic of human (...) communicative interaction is a way of constraining interaction dynamics toward the goals of a given joint action by constructing and altering shared fields of affordances. This account embraces a pragmatist view according to which communication is a form of action aiming to influence the behavior of a target, and stands against the traditional transmission view according to which communication fundamentally serves to convey information. Understanding acts of communication as active inference under an ecological interpretation allows us to link communicative and ultimately linguistic behavior to the biological imperative of minimizing free energy and to emphasize the action-oriented nature of communicative interaction.

Teaching is hypothesized to be a species-typical behavior in humans that contributed to the emergence of cumulative culture. Several within-culture studies indicate that foragers depend heavily on social learning to acquire practical skills and knowledge, but it is unknown whether teaching is universal across forager populations. Teaching can be defined ethologically as the modification of behavior by an expert in the presence of a novice, such that the expert incurs a cost and the novice acquires skills/knowledge more (...) efficiently or that it would not acquire otherwise. One behavioral modification hypothesized to be an adaptation for teaching is ostensive communication—exaggerations of prosody and gesture that signal intent to transmit generalizable knowledge and indicate the intended receiver. On this view, the use of ostensive communication in conjunction with the transmission of generalizable knowledge constitutes evidence of teaching. Oral storytelling appears to meet these criteria: Indigenous peoples regard their traditions as important sources of ecological and social knowledge, and oral storytelling is widely reported to employ paralinguistic communication. To test this hypothesis, descriptions of performed narrative in forager societies were coded for the use of 14 ostensive-communicative behaviors and the presence of generalizable knowledge. Although biased toward North America, the study sample comprised 53 forager cultures spanning five continents, 34 language families, and diverse biomes. All cultures evinced the predicted behaviors. Results suggest that foragers use storytelling as a mode of instruction, thus providing cross-cultural evidence of teaching in forager populations. (shrink)

Memory is a capacity that enables an agent’s behavior to be modified and shaped by its past experience. Given this characterization, two central questions arise. First, what are the mechanisms by which such behavioral modifications are produced—that is, how does memory function? Second, should memory be treated as a unitary capacity or are there fundamentally different kinds of memory that should be distinguished? These two questions have been central throughout the long history of philosophical inquiry into memory and the (...) shorter but rich history of empirical memory research. Researchers have debated, on the one hand, the nature of memory mechanisms and processes and, on the other hand, the merits of rival taxonomies of memory. As memory is widely recognized as playing a central role in shaping human experience and cognition, this research is essential for advancing both theoretical knowledge and practical applications across domains as diverse as mental health, education, and artificial intelligence.
