Dispositional Insight Scale: Development and Validation of a Tool That Measures Propensity Toward Insight In Problem Solving

This article reports the development of a brief self-report measure of dispositional insight problem solving, the Dispositional Insight Scale (DIS). From a representative Australian database, 1,069 adults (536 women and 533 men) completed an online questionnaire. An exploratory and confirmatory factor analysis revealed a 5-item scale, with all items loading onto a single factor. Internal consistency was acceptable with a Cronbach’s alpha of .74. The DIS showed convergent validity with other constructs that are theoretically related to insight: High need for cognition, intuition and positive affect. Normative data for the scale are also reported. The DIS appears to be useful for measuring a disposition toward insight in problem-solving.     

Face adaptation in an isolated population of African hunter-gatherers: Exposure influences perception of other-ethnicity faces more than own-ethnicity faces

Previous experiments have demonstrated that exposure to faces can change the perception of normality in new faces, such that faces similar to those at exposure appear more normal. Here we examined how experience influences adaptation effects in African Hadza hunter-gatherers, who have limited experience with White faces. We exposed participants to sets of either Hadza or White European faces that were manipulated to possess either wide-spaced or narrow-spaced eyes. We collected normality judgments both pre-exposure and post-exposure by showing pairs of images, one with wide-spaced and one with narrow-spaced eyes. Examining the difference between the pre-exposure and post-exposure judgments revealed that participants selected an increased number of images that were congruent with the faces to which they had been exposed. The change in normality judgments was strongest for White faces, suggesting that representations of White ethnicity faces are more malleable and less robust to adaptation, potentially because of the decreased experience that individuals had with them. A second experiment using the same test stimuli with a sample of White participants revealed equivalent adaptation effects for both Hadza and White faces. These data highlight the role of experience on the high-level visual adaptation of faces.     

‘A higher degree of scholarship’: Pagans and the language of scholarly authority

Through an exploration of the intellectual history and contemporary writings of the Pagan movement, this study will examine the lineage of ‘knowledge-based’ authority in contemporary Paganism. In particular, it will illuminate how the intellectual lineage of Pagan writings helped contemporary writers respond to a moment of crisis in Paganism, and it will provide an explanation for the traditionalised use of the rhetorical modes of scholarly authority among Pagan writers.     

Identity continuity and loss after death,divorce, and job loss

This paper examined the relationship of constructs identified by identity continuity and attachment theories of grief to adjustment to loss from the framework of identity theory. Connections between loss salience, identity construal, and balance of identity construal on grief intensity via their association with post-loss identity disruption were examined across three types of self-relevant losses; death of a family member, job loss, or divorce. We hypothesized that lower salience, higher endorsement of identity attributes represented by relational and individualistic self-construals, and an overall balance across identity attributes would be related to decreased grief severity across all types of loss. Results supported hypotheses with the exception that the hypothesized ameliorative effect of increases in relational self-construal was only seen in the bereaved group.     

Recognition during recall failure: Semantic feature matching as a mechanism for recognition of semantic cues when recall fails

Research suggests that a feature-matching process underlies cue familiarity-detection when cued recall with graphemic cues fails. When a test cue (e.g., potchbork) overlaps in graphemic features with multiple unrecalled studied items (e.g., patchwork, pitchfork, pocketbook, pullcork), higher cue familiarity ratings are given during recall failure of all of the targets than when the cue overlaps in graphemic features with only one studied target and that target fails to be recalled (e.g., patchwork). The present study used semantic feature production norms (McRae et al., Behavior Research Methods, Instruments, & Computers, 37, 547–559, 2005) to examine whether the same holds true when the cues are semantic in nature (e.g., jaguar is used to cue cheetah). Indeed, test cues (e.g., cedar) that overlapped in semantic features (e.g., a_tree, has_bark, etc.) with four unretrieved studied items (e.g., birch, oak, pine, willow) received higher cue familiarity ratings during recall failure than test cues that overlapped in semantic features with only two (also unretrieved) studied items (e.g., birch, oak), which in turn received higher familiarity ratings during recall failure than cues that did not overlap in semantic features with any studied items. These findings suggest that the feature-matching theory of recognition during recall failure can accommodate recognition of semantic cues during recall failure, providing a potential mechanism for conceptually-based forms of cue recognition during target retrieval failure. They also provide converging evidence for the existence of the semantic features envisaged in feature-based models of semantic knowledge representation and for those more concretely specified by the production norms of McRae et al. (Behavior Research Methods, Instruments, & Computers, 37, 547–559, 2005).     

“Strong” narrativity—a response to Hutto

This paper responds to Dan Hutto’s paper, ‘Narrative Self-Shaping: a Modest Proposal’. Hutto there attacks the “strong” narrativism defended in my recent book, ‘Self, Value and Narrative’ and in recent work by Marya Schechtman. I rebut Hutto’s argument that non-narrative forms of evaluative self-shaping can plausibly be conceived, and defend the notion of implicit narrative against his criticisms. I conclude by briefly indicating some difficulties that arise for the “modest” form of narrativism that Hutto defends.     

Awareness of memory task impairment versus everyday memory difficulties in dementia

The study investigated different types of awareness of memory dysfunction in dementia, specifically judgements concerning memory task performance or appraisal of everyday memory functioning and also exploring the neuropsychological correlates of such awareness. This was investigated in 76 people with dementia, comprising 46 patients with Alzheimer's disease (AD) and 30 patients with vascular dementia (VaD). The Memory Awareness Rating Scale (Clare et al., 2002, Neuropsychol Rehabil, 12, 341–362) was used, which includes an Objective‐Judgement Discrepancy (OJD) technique involving comparison of subjective evaluation of performance on specific memory tasks with actual performance, and a Subjective Rating Discrepancy (SRD) technique, which compares self versus informant judgement of everyday memory function. The AD and VaD groups showed lower awareness than a normal control group for both types of measures, the AD group showing less awareness than the VaD group on the OJD measure. Regression analyses supported associations for both groups between memory impairment and the OJD measure and between naming impairment and the SRD measure. The findings are discussed in terms of neurocognitive theories accounting for loss of awareness in dementia.     

Executive control in older Welsh monolinguals and bilinguals

Evidence for a bilingual advantage in executive control has led to the suggestion that being bilingual might protect against late-life cognitive decline. We assessed the performance of socially homogeneous groups of older (≥60 years) bilingual Welsh/English (n?=?50) and monolingual English (n?=?49) speakers on a range of executive control tasks yielding 17 indices for comparison. Effect sizes (>.2) favoured monolinguals on 10 indices, with negligible differences observed on the remaining 7 indices. Univariate analyses indicated that monolinguals performed significantly better on 2 of 17 indices. Multivariate analysis indicated no significant overall differences between the two groups in performance on executive tasks. Older Welsh bilinguals do not show a bilingual advantage in executive control, and where differences are observed, these tend to favour monolinguals. A possible explanation may lie in the nature of the socio-linguistic context and its influence on cognitive processing in the bilingual group.
