Training to use voice onset time as a cue to talker identification induces a left-ear/right-hemisphere processing advantage

We examined the effect of perceptual training on a well-established hemispheric asymmetry in speech processing. Eighteen listeners were trained to use a within-category difference in voice onset time (VOT) to cue talker identity. Successful learners (n=8) showed faster response times for stimuli presented only to the left ear than for those presented only to the right. The development of a left-ear/right-hemisphere advantage for processing a prototypically phonetic cue supports a model of speech perception in which lateralization is driven by functional demands (talker identification vs. phonetic categorization) rather than by acoustic stimulus properties alone.     

Playing Patient, Playing Doctor: Munchausen Syndrome, Clinical S/M, and Ruptures of Medical Power

This article deploys sadomasochism as a framework for understanding medical practice on an institutional level. By examining the case of the factitious illness Munchausen syndrome, this article analyzes the operations of power in the doctor-patient relationship through the trope of role-playing. Because Munchausen syndrome causes a disruption to the dyadic relationship between physicians and patients, a lens of sadomasochism highlights dynamics of power in medical practice that are often obscured in everyday practice. Specifically, this article illustrates how classification and diagnosis are concrete manifestations of the mobilization of medical power.     

That's a boy's toy: gender-typed knowledge in toddlers as a function of mother's marital status

A child who is highly gender schematic readily uses gender when processing new information. In the current study, we examined whether and how family structure predicts a child's level of gender-typed knowledge (as assessed by a gender-stereotype sorting task) once the category of gender is in place (as assessed by a gender-labeling task). It was predicted that children from more "traditional" family structures (married mothers) would have more gender-typed knowledge compared to children from less traditional families (unmarried mothers). Moreover, we explored if this relationship would be related to, at least in part, the greater frequency of androgynous behaviors (i.e., both masculine and feminine household activities) an unmarried mother performs. Twenty-eight children (age 2 to 3) were tested at local childcare centers. The mother of each child reported her marital status as well as how often she engaged in stereotypically masculine and feminine behaviors. As expected, mothers' marital status was associated with children's level of gender-typed knowledge, such that children with unmarried mothers had less gender-typed knowledge, in part due to the unmarried mother's greater frequency of androgynous behaviors. Implications for children's acquisition of gender-related stereotypes and the possible benefit of having mothers model both masculine and feminine behaviors are discussed.     

“Why didn’t you just ask?” Underestimating the discomfort of help-seeking

Across four studies we demonstrate that people in a position to provide help tend to underestimate the role that embarrassment plays in decisions about whether or not to ask for help. As a result, potential helpers may overestimate the likelihood that people will ask for help (Studies 1 and 2). Further, helpers may be less inclined to allocate resources to underutilized support programs than help-seekers because they are less likely to attribute low levels of use to help-seekers’ concerns with embarrassment (Study 3). Finally, helpers may misjudge the most effective means of encouraging help-seeking behavior - emphasizing the practical benefits of asking for help, rather than attempting to assuage help-seekers’ feelings of discomfort (Study 4).     

Chess as a Behavioral Model for Cognitive Skill Research: Review of Blindfold Chess by Eliot Hearst and John Knott

This multifaceted work on chess played without sight of the pieces is a sophisticated psychologist's examination of this topic and of chess skill in general, including a detailed and comprehensive historical account. This review builds on Hearst and Knott's assertion that chess can provide a uniquely useful model for research on several issues in the area of cognitive skill and imagery. A key issue is the relationship between viewing a stimulus and mental imagery in the light of blindfold chess masters' consistent reports that they do not use or have images. This review also proposes a methodology for measuring and quantifying an individual's skill shortfall from a theoretical maximum. This methodology, based on a 1951 proposal by Claude Shannon, is applicable to any choice situation in which all the available choices are known. The proposed “Proficiency” measure reflects the equivalent number of “yes—no” questions that would have been required to arrive at a best choice, considering also the time consumed. As the measure provides a valid and nonarbitrary way to compare different skills and the effects of different independent variables on a given skill, it may have a wide range of applications in cognitive skill research, skill training, and education.     

Moral Evil and Leibniz’s Form/Matter Defense of Divine Omnipotence

The purpose of this paper is to demonstrate that Leibniz’s form/matter defense of omnipotence is paradoxical, but not irretrievably so. Leibniz maintains that God necessarily must concur only in the possibility for evil’s existence in the world (the form of evil), but there are individual instances of moral evil that are not necessary (the matter of evil) with which God need not concur. For Leibniz, that there is moral evil in the world is contingent on God’s will (a dimension of divine omnipotence), with the result that even though it is necessary that God exerts his will, there are particular products of his will that are contingent and unnecessary—including human moral evil. If there are instances of evil which are contingent on God’s will and yet unnecessary, then the problematic conclusion for Leibniz’s view must be that human evil depends upon divine concurrence, not just for its possibility in the world (which is necessary) but for its instance (which is contingent). If the form/matter defense of omnipotence contains a true paradox, then God concurs in the form as well as the matter of evil. To assuage this difficulty for Leibniz, I will argue that he could either give up an Augustinian notion of evil, or rely upon a distinction between *potenta absoluta* and *potenta ordinate*, which was popular among important thinkers in the medieval period.     

Alternative Factor Models and Heritability of the Short Leyton Obsessional Inventory—Children’s Version

An alternative models framework was used to test three confirmatory factor analytic models for the Short Leyton Obsessional Inventory-Children’s Version (Short LOI-CV) in a general population sample of 517 young adolescent twins (11–16 years). A one-factor model as implicit in current classification systems of Obsessive–Compulsive Disorder (OCD), a two-factor obsessions and compulsions model, and a multidimensional model corresponding to the three proposed subscales of the Short LOI-CV (labelled Obsessions/Incompleteness, Numbers/Luck and Cleanliness) were considered. The three-factor model was the only model to provide an adequate explanation of the data. Twin analyses suggested significant quantitative sex differences in heritability for both the Obsessions/Incompleteness and Numbers/Luck dimensions with these being significantly heritable in males only (heritability of 60% and 65% respectively). The correlation between the additive genetic effects for these two dimensions in males was 0.95 suggesting they largely share the same genetic risk factors.     

Episodic and semantic remote autobiographical memory in ageing

Many laboratory studies have demonstrated an age effect on episodic memory which is in contrast with the preservation of semantic memory. The aim of this study was the assessment of age effects on autobiographical memory according to the length of the retention interval, taking into account the episodic and semantic components. A total of 52 subjects, aged between 40 and 79, were divided into four age groups. They were tested with a sophisticated autobiographical questionnaire consisting of two tasks, one involving the recall of semantic information and another the recall of episodic events. Results revealed that episodic recall deteriorated more with age and retention interval than semantic recall. These data, gathered using an ecological test, confirm age differences demonstrated by laboratory tests on the episodic-semantic distinction. Furthermore, the profile of results obtained for the recall of specific detailed events, and analysed according to age of encoding, confirms the distribution of episodic memories across the lifespan, as modelled by Rubin, Wetzler, and Nebes (1986) with the cue-word technique.     

The measurement of participant-reported memory across diverse populations and settings: a systematic review and meta-analysis of the Multifactorial Memory Questionnaire

ABSTRACT

The Multifactorial Memory Questionnaire (MMQ) is a participant-reported measure of memory satisfaction, ability, and strategy use. Initially validated with healthy older adults, it has since been used in many different populations and settings for a variety of purposes. We conducted a systematic review and meta-analysis of the measurement properties of the MMQ across multiple, diverse studies. Methods: The study was designed using the Consensus-Based Standards for the Selection of Health Measurement Instruments and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We calculated aggregate statistics and evaluated the methodological quality of 29 studies retrieved from PsycINFO, MEDLINE, EMBASE, and Web of Science. Results: Analyses revealed high-quality evidence for internal consistency, stability, measurement error, convergent validity, and known-groups validity of the three MMQ scales. There was moderate-quality evidence for responsiveness and structural validity, with some studies identifying separate factors for internal and external memory strategy use. Measurement properties were similar across languages, participant samples, and study designs. Conclusions: The MMQ is a valid, reliable, and responsive measure across diverse settings and populations. Future research is needed to determine whether more detailed information can be obtained from the scales, specifically, internal versus external strategy use.
