Philosophical arguments for the rationality of Bayesian conditioning often use assumptions and concepts from epistemic logic without fully explicating them. In this work, we present a general dynamic epistemic logic framework to analyze logical properties of (Bayesian) learning scenarios. We argue that Perfect-Recall is an important epistemic principle at the heart of the project of justifying Bayesian conditioning. In such epistemic logic formulation, Perfect-Recall is not really about memory, but about the agent’s general ability to know how they (...) came to know what they know. Following the existing literature, we use Monty Hall style cases to demonstrate the connection between PerfectRecall and the commitments of Bayesian conditioning. (shrink)

An intuition about consciousness known as the 'Awareness Principle' states: For any mental state M of a subject S, M is conscious only if S has an 'inner awareness' of M. Some have recently defended this principle by revising the 'memory argument' first offered by the sixth-century Buddhist philosopher Dignāga: from the fact that an experience can be episodically remembered, it should follow that a subject must have been aware of that experience. In response, I argue that defenders of the (...) memory argument haven’t convincingly established the episodic memorability of experience, because they haven’t defused a countervailing claim that conscious perceptual experience is phenomenologically 'transparent'. This claim, if true, would suggest that what one can episodically remember is just how the (external or internal) world appeared through one's 'outer awareness', rather than how the past experience itself appeared through one's inner awareness. I further argue that the memory argument can accommodate phenomenological transparency only at the expense of making the Awareness Principle trivial. The memory argument defender may then claim that there is some non-introspectible feature of a past experience that is episodically memorable, namely, that experience's subjective character or phenomenal 'for-me-ness'. In response, I develop an objection from the tenth-century Śaiva philosopher Utpaladeva against the possibility of recalling a past experience's subjective character as such. Overall, while the objections this paper raises cannot falsify the Awareness Principle directly, they may motivate its proponents to recall their support for the memory argument. (shrink)

Recent work in mechanistic interpretability has studied how large language models recall facts stored in their weights. This paper argues that factual recall points to something broader: a general kind of operation in deep learning models, which I call feature recall. The core observation is that a linear projection can be read as retrieving stored information scaled by input activations. I define feature recall, show it applies across architectures, and contrast it with the established paradigm of (...) feature combination. I also consider how cases of feature recall might be mechanistically identified. The account offers philosophers a new conceptual tool for understanding deep learning and points to empirical research directions for mechanistic interpretability research. (shrink)

Bootstrapping is a suspicious form of reasoning that seems to allow agents to gain knowledge about the reliability of their sources of information ‘from thin air’, without gathering independent evidence about those sources. The bootstrapping problem is the problem of explaining what is wrong with bootstrapping reasoning. I identify one defect in bootstrapping reasoning by making explicit an implicit dynamic assumption which is made in such reasoning, involving the perfect-recall principle. The defect stems from a fallacious reasoning pattern that (...) arises by misapplication of perfect-recall. I argue that understanding this defect can explain away some aspects of bootstrapping reasoning. (shrink)

We revisit the sequential search problem by Hey.

Our results provide clear evidence for Hey’s conjecture that recall negatively affects performance in sequential search. With experience, however, search behavior with and without recall converges toward the optimal reservation rule. We (...) further find that the utilization of optimal reservation rules is independent from the stochastic nature of the search cost. (shrink)

Episodic memory, with its emphasis on temporal–spatial contexts, has been a longstanding focus in memory research. While previous studies have investigated the role of emotion in temporal source memory using emotionally charged stimuli, such as emotional words or images, the influence of a separated emotional context remains less explored. This study sought to understand the impact of separate emotional contexts on temporal source memory. Participants were shown Chinese characters alongside separate emotional contexts (i.e. a neutral or negative picture) and then (...) engaged in either a retrieval practice or a control condition. Finally, they were tested for recognition, temporal source memory, and emotional source memory for all the learned characters. Results revealed that a negative emotional context, unlike a neutral setting, enhanced the accuracy of temporal memory for adjacent neutral characters. However, this negative context reduced the accuracy of recalling the associated emotion. Importantly, the boost in temporal memory due to the emotional context remained even when participants were unsure or mistaken about the associated emotion. This study demonstrates the complex interplay between emotion and temporal memory, underscoring the enhancement effect of separated emotional contexts on temporal recall, irrespective of explicit emotional memory retrieval.

The computations involved in statistical learning have long been debated. Here, we build on work suggesting that a basic memory process, chunking, may account for the processing of statistical regularities into larger units. Drawing on methods from the memory literature, we developed a novel paradigm to test statistical learning by leveraging a robust phenomenon observed in serial recall tasks: that short‐term memory is fundamentally shaped by long‐term distributional learning. In the statistically induced chunking recall (SICR) task, participants are (...) exposed to an artificial language, using a standard statistical learning exposure phase. Afterward, they recall strings of syllables that either follow the statistics of the artificial language or comprise the same syllables presented in a random order. We hypothesized that if individuals had chunked the artificial language into word‐like units, then the statistically structured items would be more accurately recalled relative to the random controls. Our results demonstrate that SICR effectively captures learning in both the auditory and visual modalities, with participants displaying significantly improved recall of the statistically structured items, and even recall specific trigram chunks from the input. SICR also exhibits greater test–retest reliability in the auditory modality and sensitivity to individual differences in both modalities than the standard two‐alternative forced‐choice task. These results thereby provide key empirical support to the chunking account of statistical learning and contribute a valuable new tool to the literature. (shrink)

Previous research has shown that disgusting photographs are better remembered than frightening photographs, even when the two image types have equivalent valence and arousal. However, this work did not control for potential differences in organisation between the disgusting and frightening stimuli that could account for enhanced memory for disgusting photographs. The current research therefore tested whether differences in recall between disgusting and frightening photographs persist when differences in organisation are eliminated. Using a set of disgusting and frightening photographs matched (...) for interrelatedness, Study 1 found that participants recalled more disgusting photographs than frightening photographs. This effect was mediated by increased attention to the disgusting photographs. Study 2 used Latent Semantic Analysis to further interrogate the relatedness of the photographs, providing converging evidence that organisation does not account for enhanced recall of disgusting photographs.

Significant individual differences exist in dream recall frequency but some variance is likely attributable to instrument choice in measuring DRF. Three hundred and fifty eight participants estimated their weekly DRF and recorded their dreams in either a narrative log or checklist log for 2–5 weeks. There was an early peak in DRF within the first week of both types of prospective logs after which DRF remained relatively stable. Although the two groups did not differ in their estimated DRF, significantly (...) fewer dreams were reported per week on the narrative logs and only checklist logs yielded significantly higher DRF than participants’ questionnaire estimates. The interactions between DRF measures did not vary across groups with low, medium or high baseline levels of DRF. Keeping a dream log does not necessarily increase DRF and narrative logs’ time consuming nature can impact subjects’ motivation to report all of their dreams over time. (shrink)

BackgroundLimited research has been conducted on explanations and understandings of biobanking for future genomic research in African contexts with low literacy and limited healthcare access. We report on the findings of a sub-study on participant understanding embedded in a multi-disease community health screening and biobank platform study known as ‘Vukuzazi’ in rural KwaZulu-Natal, South Africa.MethodsSemi-structured interviews were conducted with research participants who had been invited to take part in the Vukuzazi study, including both participants and non-participants, and research staff that (...) worked on the study. The interviews were transcribed, and themes were identified from the interview transcripts, manually coded, and thematically analysed.ResultsThirty-nine individuals were interviewed. We found that the research team explained biobanking and future genomic research by describing how hereditary characteristics create similarities among individuals. However, recollection and understanding of this explanation seven months after participation was variable. The large volume of information about the Vukuzazi study objectives and procedures presented a challenge to participant recall. By the time of interviews, some participants recalled rudimentary facts about the genetic aspects of the study, but many expressed little to no interest in genetics and biobanking.ConclusionParticipant’s understanding of information related to genetics and biobanking provided during the consent process is affected by the volume of information as well as participant’s interest (or lack thereof) in the subject matter being discussed. We recommend that future studies undertaking biobanking and genomic research treat explanations of this kind of research to participants as an on-going process of communication between researchers, participants and the community and that explanatory imagery and video graphic storytelling should be incorporated into theses explanations as these have previously been found to facilitate understanding among those with low literacy levels. Studies should also avoid having broader research objectives as this can divert participant’s interest and therefore understanding of why their samples are being collected. (shrink)

The aim of this study is to assess patients' recall of their previous research participation. Recall was established during interviews and compared with entries from clinical notes. Participants were 49 patients who had previously participated in different types of research. Of the 49 patients, 45 (92%) interviewees recalled 69 of 109 (63%) study participations. Level of recall varied according to the type of research, some participants clearly recalled the details of research aims, giving consent and research procedures. (...) Others recalled procedures (e.g. DNA testing) but were unclear about their purpose. There was no significant effect of time on recall. Some types of research participation (e.g. DNA testing) may be recalled as clinical care. We argue that such misunderstandings may have the potential to undermine participants' ongoing consent, particularly in ongoing/longitudinal studies. Valid consent may be best achieved by re-assessing the scope of consent and relating it to the nature of the interventions themselves rather than the reasons for undertaking them. (shrink)

Substantial average gender differences in childhood play behaviour and occupational interests have been well-documented. Recent research shows that childhood gender-related play behaviour longitudinally predicts gender-related occupational interests in adolescence. The first aim of the present study was to extend this recent finding by examining whether university students’ recalled childhood gender-related play behaviour predicts their current gender-related occupational interests. The second aim of the present study was to investigate whether gender-related socio-cognitive processes mediate the relation between childhood play behaviour and subsequent (...) occupational interests. University students completed scales assessing recalled childhood gender-related play behaviour, gender-related occupational interests, gender typicality, gender contentedness, agentic goal endorsement, communal goal endorsement, and gender-related occupational stereotype flexibility. In the present study, recalled childhood gender-related play behaviour predicted gender-related occupational interests in both men and women. In men, gender typicality and gender contentedness mediated the play-interests link. In women, gender typicality and communal goal endorsement mediated the play-interests link. The present study provides further evidence that childhood gender-related play behaviour is related to subsequent gender-related occupational interests. Although the current study has a correlational design, one interpretation of the current findings is that childhood play may influence socio-cognitive processes, such as gender compatibility and goal endorsement, which may in turn shape occupational interests.

What has happened to the project of ‘symmetrical anthropology’ in the last twenty years? What difference does it make to consider a multiplicity of cultures over the background of a unified nature, or a multiplicity of natures in addition to a multiplicity of cultures? In which way does it open up another type of scientific anthropology, no longer based on comparison but on ‘diplomacy’? Can modernity, as an interpretation of the former West, be recalled? Translated by Stephen Muecke.

The objective of the article is to recall the European philosophical basis of the philosophical culture, inextricably connected with ancient Greece and its language. Plato’s philosophy is in the very core of the culture and its salient component is the doctrine of anamnesis. The elements of the doctrine are dispersed in numerous dialogues, particularly in Meno, Phaedo, Phaedrus, therefore they are given more attention. Platonic reflection on anamnesis is related to his view on the soul whose development is associated (...) with the process of cognizing, being essentially tantamount to recalling of what the soul saw before its imprisonment in the body. The role of myth in Plato’s philosophy, as well as in European culture as a whole, has been discussed, along with the main subject. On the background of the Platonic thought, examples of its reception in Polish Renaissance philosophy and in the poetry of the Romantic period has been presented. (shrink)

Prior research on the effectiveness of ethics education has yielded mixed results. In this sample of 686 employed adults, we found the majority felt there was little or no emphasis on ethics in their undergraduate program, and they felt poorly prepared to deal with ethical dilemmas at work. Among business, sciences, and liberal arts majors, those who majored in the sciences reported the lowest level of preparation for dealing with ethics issues. Management and law classes were the ones most frequently (...) recalled by respondents as emphasizing ethics. Respondents made suggestions for improving undergraduate ethics preparation. (shrink)

Evidence suggests that research participants often fail to recall much of the information provided during the informed consent process. This study was conducted to determine the proportion of consent information recalled by drug court participants following a structured informed consent procedure and the neuropsychological factors that were related to recall. Eighty-five participants completed a standard informed consent procedure to participate in an ongoing research study, followed by a 17-item consent quiz and a brief neuropsychological battery 2 weeks later. (...) Participants performed within the normal range on most of the neuropsychological measures, although roughly one third showed deficits on measures of executive functioning. Participants failed to recall over 65% of the consent information within 2 weeks of entering the study, and their recall was significantly correlated with verbal IQ, drug problem severity, reading ability, memory, and attention. These factors may be useful in determining whether research participants require enhanced consent procedures. (shrink)

This study was aimed at investigating whether the retrieval of episodic information is more likely to be associated with the recognition of personally familiar faces than voices. Hence, the proportions of episodic memories recalled following the recognition of personally known faces and voices was assessed, using a modified version of the Remember/Know paradigm. Present findings showed that episodic information was more often retrieved from familiar faces than from familiar voices. Furthermore, this advantage of faces over voices was significant even when (...) face recognition was rendered similar as that for voices by blurring the faces. The same pattern of results was observed regarding semantic information retrieval. These results and their implications for person recognition models, as well as the potential role of the relative distinctiveness of faces and voices, are discussed. (shrink)

Background: Although performance on the category fluency test is influenced by many cognitive functions, item-level scoring methods of CFT performance might be a promising way to capture aspects of semantic memory that are less influenced by intervenient abilities. One such approach is based on the calculation of correlation coefficients that quantify the association between item-level features and the serial order with which words are recalled.Methods: We explored the neural underpinnings of 10 of these correlational indices in a sample of 40 (...) healthy adults who completed a classic 1-min CFT and an MRI protocol inclusive of T1-weighted and resting-state fMRI sequences for the evaluation of the default-mode network. Two sets of linear models were defined to test the association between neural maps and each correlational index: a first set in which major demographic and clinical descriptors were controlled for and a second set in which, additionally, all other 9 correlational indices were regressed out.Results: In the analysis of the DMN, ‘SRO-frequency’, ‘SRO-dominance’ and ‘SRO-body-object interaction’ correlational indices were all negatively associated with the anterior portion of the right temporoparietal junction. The ‘SRO-frequency’ correlational index was also negatively associated with the right dorsal anterior cingulate and the ‘SRO-dominance’ correlational index with the right lateral prefrontal cortex. From the second set of models, the ‘SRO-typicality’ correlational index was positively associated with the left entorhinal cortex. No association was found in relation to grey matter maps.Conclusion: The ability to retrieve more difficult words during CFT performance as measured by the correlational indices between SRO and item-level descriptors is associated with DMN expression in regions deputed to attentional reorienting and processing of salience of infrequent stimuli and dominance status. Of all item-level features, typicality appears to be that most closely linked with entorhinal functioning and may thus play a relevant role in assessing its value in testing procedures for early detection of subtle cognitive difficulties in people with suspected Alzheimer’s degeneration. Although exploratory, these findings warrant further investigations in larger cohorts. (shrink)

Using the concept of postmemory—coined by Mariane Hirsch—this paper explores the role of photographs in recalling past trauma in two families who participated in the anticommunist armed resistance in Romania. Members of these families were executed and the survivors had to endure further persecution. The interviews revealed that some pictures offer the frame for remembering suppressed memories. The images have peculiar meanings for different generations of the same family. For the participants in this study, seeing the photographs equates to reliving (...) a past trauma and giving a new meaning to it. Pictures function as realms of encounter and reconciliation between present and past generations of the same family. The first outcome of the process is memory recovery; in this, people also recover their identity and the result is transgenerational healing. Some of the interviews discussed in this paper were done with members of my family. (shrink)
