Three Abductive Solutions to the Meno Paradox – with Instinct, Inference, and Distributed Cognition

This article analyzes three approaches to resolving the classical Meno paradox, or its variant, the learning paradox, emphasizing Charles S. Peirce’s notion of abduction. Abduction provides a way of dissecting those processes where something new, or conceptually more complex than before, is discovered or learned. In its basic form, abduction is a “weak” form of inference, i.e., it gives only tentative suggestions for further investigation. But it is not too weak if various sources of clues and restrictions on the abductive search are taken into account. We present three, complementary versions of abduction: (1) as a sort of guessing instinct or expert-like intuition, where unconscious clues are important; (2) as a form of inference, where a strategic point of view is essential; and (3) as a part of distributed cognition and mediated activity, where the interaction with the material, social, and cultural environment is emphasized. Our starting point is Peirce’s own notion of abduction, but we broaden the perspective, especially to the direction of distributed cognition.     

What constitutes an episode in episodic memory?

The idea of episodic memory implies the existence of a process that segments experience into episodes so that they can be stored in memory. It is therefore surprising that the link between event segmentation and the organization of experiences into episodes in memory has not been addressed. We found that after participants read narratives containing temporal event boundaries at varying locations in the narrative, their long-term associative memory for information across event boundaries was lower than their memory for information within an event. This suggests that event segmentation during encoding resulted in segmentation of those same events in memory. Further, functional imaging data revealed that, across participants, brain activity consistent with the ongoing integration of information within events correlated with this pattern of mnemonic segmentation. These data are the first to address the mechanisms that support the organization of experiences into episodes in long-term memory.     

Are visual cue masking and removal techniques equivalent for studying perceptual skills in sport?

The spatial-occlusion paradigm makes use of two techniques (masking and removing visual cues) to provide information about the anticipatory cues used by viewers. The visual scene resulting from the removal technique appears to be incongruous, but the assumed equivalence of these two techniques is spreading. The present study was designed to address this issue by combining eye-movement recording with the two types of occlusion (removal versus masking) in a tennis serve-return task. Response accuracy and decision onsets were analysed. The results indicated that subjects had longer reaction times under the removal condition, with an identical proportion of correct responses. Also, the removal technique caused the subjects to rely on atypical search patterns. Our findings suggest that, when the removal technique was used, viewers were unable to systematically count on stored memories to help them accomplish the interception task. The persistent failure to question some of the assumptions about the removal technique in applied visual research is highlighted, and suggestions for continued use of the masking technique are advanced.     

Gleaning Information for Cognitive Operations from Don’t Know Responses in Cognitive and Noncognitive Assessments

The Don’t Know (DK) response – taking the form of an omitted response or not-reached at the end of a cognitive test, or explicitly presented as a response option in a social survey – contains important information that is often overlooked. Direct psychometric modeling efforts for DK responses are few and far between. In this article, the linear logistic test model (LLTM) is proposed for delineating the impacts of cognitive operations for a test that contains DK responses. We assume that the DK response is a valid response. The assumption is reasonable for many situations, including low-stakes cognitive tests and attitudinal assessments. By extracting information embedded in the DK response, the method shows how DK can inform the latent construct of interest and the cognitive operations underlying the response to stimuli. Using a proven recoding scheme, the LLTM could be implemented through commonly used programs such as PROC GLIMMIX. Two simulation experiments to evaluate how well the parameters can be recovered were conducted. In addition, two real data examples, from a noncognitive test of health belief assessment and a cognitive test of knowledge in diabetes, are also presented as case studies to illustrate the LLTM for DK response.     

Maternal sensitivity behavior and infant crying, fussing and contented behavior: the effects of mother's experienced social support

Maternal sensitivity behavior, mother's experienced difficulties, experienced social support, and the amount of infant's crying, fussing and contented behavior were studied when the infants were 3 and 12 months of age. Fifty-seven Finnish low-risk mothers' sensitivity behavior was assessed by the Parent-Child Early Relational Assessment method. Infant's crying behavior was assessed by the Baby's Day Record and by the Crying Patterns Questionnaire. The Social Support Questionnaires (SSQ 1 and 2) were used to evaluate mother's experienced difficulties and support. The infants of More Sensitive (MS) mothers were more contented than those with Less Sensitive (LS) mothers. The MS mothers experienced fewer difficulties with their infants and experienced more support from their best friend and their husband than LS mothers. In addition, some gender differences were found concerning infant behavior.     

Using Statistical Models of Morphology in the Search for Optimal Units of Representation in the Human Mental Lexicon

Determining optimal units of representing morphologically complex words in the mental lexicon is a central question in psycholinguistics. Here, we utilize advances in computational sciences to study human morphological processing using statistical models of morphology, particularly the unsupervised Morfessor model that works on the principle of optimization. The aim was to see what kind of model structure corresponds best to human word recognition costs for multimorphemic Finnish nouns: a model incorporating units resembling linguistically defined morphemes, a whole‐word model, or a model that seeks for an optimal balance between these two extremes. Our results showed that human word recognition was predicted best by a combination of two models: a model that decomposes words at some morpheme boundaries while keeping others unsegmented and a whole‐word model. The results support dual‐route models that assume that both decomposed and full‐form representations are utilized to optimally process complex words within the mental lexicon.     

An Emotion Regulation Treatment for Young People With Complex Substance Use and Mental Health Issues: A Case-Series Analysis

Individuals accessing treatment within the youth alcohol and other drug (AoD) sector represent a highly vulnerable population who present with complex patterns of substance use and mental health comorbidity. Current treatments often fail to address this complexity. Emotion regulation (ER) has been identified as a promising transdiagnostic treatment target for this population of young people. The current study aimed to investigate the acceptability and feasibility of an adjunct ER intervention, ERIC (Emotion Regulation and Impulse Control) in young people receiving AoD treatment at a residential rehabilitation service. A mixed methods case series design was utilized. Ten participants aged between 16–20 years old completed 4–6 sessions of ERIC as an adjunct to their existing residential treatment. Participants undertook a post intervention feedback session and completed a number of self-report measures of ER, depression and anxiety at baseline and 2 weeks after receiving ERIC. Qualitative feedback from young people following the delivery of ERIC was positive, and suggested that ERIC was a viable and useful intervention. Participants reported that the components of ERIC, which involved metaphors and experiential exercises, were particularly beneficial and memorable. Pre-post measures indicated that 60% of the young people had both reliable and clinically significant reductions in overall emotion dysregulation, while reliable and clinically significant reductions in depression and anxiety were observed in 50% and 60% of participants respectively. Results support the acceptability of ERIC for this cohort of young people with complex substance use and mental health needs. Furthermore, these findings support the viability of delivering flexible and adjunctive ER treatments to young people seeking AoD treatment.     

Latent constructs model explaining the attachment-linked variation in autobiographical remembering

In the current study, we proposed a latent constructs model to characterise the qualitative aspects of autobiographical remembering and investigated the structural relations in the model that may vary across individuals. Primarily, we focused on the memories of romantic relationships and argued that attachment anxiety and avoidance would be reflected in the ways that individuals encode, rehearse, or remember autobiographical memories in close relationships. Participants reported two positive and two negative relationship-specific memories and rated the characteristics for each memory. As predicted, the basic memory model yielded appropriate fit, indicating that event characteristics (EC) predicted the frequency of rehearsal (RC) and phenomenology at retrieval (PC). When attachment variables were integrated, the model showed that rehearsal mediated the link between anxiety and PC, especially for negative memories. On the other hand, for avoidance EC was the key factor mediating the link between avoidance and RC, as well as PC. Findings were discussed with respect to autobiographical memory functions emphasising a systematically, integrated framework.     

Effects of an Islamic-based gratitude strategy on Muslim students’ level of happiness

This study examined the effects of an Islamic-based expressive gratitude strategy in comparison to a secular-based expressive gratitude strategy and a control group in enhancing Muslims’ level of happiness. It was hypothesised that practising the Islamic-based gratitude exercise (by associating blessings with Allah) would result in higher happiness level over time, compared to the happiness level of Muslim participants practising the secular-based gratitude exercise (without specific association) or the control group (attending to details of daily life). Sixty students were randomly assigned into one of three groups and over a period of 16 days were asked to practise the respective exercises daily. They were assessed for pre- and post-happiness measures. Results generally supported the hypothesis, and suggested that the Islamic-based gratitude is beneficial in raising participants’ happiness level, as it fits with their beliefs and values. Implications of the results for including Islamic-oriented intervention to promote Muslim happiness are discussed.     

The effects of affect and input source on flashbulb memories

Flashbulb memories of shocking news (Challenger Explosion, death of Princess Diana, Pearl Harbour and Iraq bombings) were employed to test two hypotheses: encoding emotion enhances memory and how one gets the shocking news will help determine the nature of what is recalled. Different groups of subjects (Total = 2405) remembered their discoveries at delays ranging from 2 weeks to 50 years on three memory measures: a free and probed recall test of their flashbulb discovery, and a probed recall of the facts concerning the events themselves. Subjects were grouped according to the source of their discovery (Media vs. Person), affect at encoding (calm vs. upset) and recounts (few vs. many). The results indicated that how one learns of shocking news determined the type and extent of the resultant memory. ‘Media’ subjects remembered more facts whereas ‘person’ subjects recalled more of their personal discoveries regardless of the initial flashbulb inspiring event.
