Feasibility and validity of the structured attention module among economically disadvantaged preschool-age children

Rooted in the theory of attention put forth by Mirsky, Anthony, Duncan, Ahearn, and Kellam (1991), the Structured Attention Module (SAM) is a developmentally sensitive, computer-based performance task designed specifically to assess sustained selective attention among 3- to 6-year-old children. The current study addressed the feasibility and validity of the SAM among 64 economically disadvantaged preschool-age children (mean age = 58 months; 55% female); a population known to be at risk for attention problems and adverse math performance outcomes. Feasibility was demonstrated by high completion rates and strong associations between SAM performance and age. Principal Factor Analysis with rotation produced robust support for a three-factor model (Accuracy, Speed, and Endurance) of SAM performance, which largely corresponded with existing theorized models of selective and sustained attention. Construct validity was evidenced by positive correlations between SAM Composite scores and all three SAM factors and IQ, and between SAM Accuracy and sequential memory. Value-added predictive validity was not confirmed through main effects of SAM on math performance above and beyond age and IQ; however, significant interactions by child sex were observed: Accuracy and Endurance both interacted with child sex to predict math performance. In both cases, the SAM factors predicted math performance more strongly for girls than for boys. There were no overall sex differences in SAM performance. In sum, the current findings suggest that interindividual variation in sustained selective attention, and potentially other aspects of attention and executive function, among young, high-risk children can be captured validly with developmentally sensitive measures.     

Implicit memory bias,explicit memory bias,and anxiety

Abstract

Normals high, medium, and low in trait anxiety performed two encoding tasks (one predominantly data-driven and the other conceptually driven) on threat-related and neutral words, followed by tests of word completion, cued recall, and free recall. Memory performance indicated the existence of negative memory biases in the high trait-anxious group, but it was generally not possible to decide whether the biases were associated with trait anxiety rather than with depression. The biases were obtained mainly when there was a match between the processes at encoding and those at the time of test, whether the matching processes were predominantly data-driven or conceptually driven. Implications of these findings for implicit and explicit memory biases associated with high trait anxiety are discussed.     

“Part of the Very Concept”: Wittgensteinian Moral Philosophy1

X is “part of the very concept” of Y. This formulation recurs throughout Raimond Gaita's philosophy and informs Christopher Cordner's. I elucidate the formulation's meaning and the nature of the necessity posited, then conclude with a criticism. One cannot love evil. One cannot love cow dung. For Gaita, these claims differ in type. The first testifies to a conceptual relation, but the second to a “mere fact.” I see no clear basis for assigning to claims one type over another, which challenges the footing of Wittgensteinian moral philosophy. Why do no moral“mere facts” partly define our form of life?     

La comunicación entre pequeños gorilas criados en cautividad y sus cuidadoras

Resumen

La presente investigación tiene como sujetos a dos pequeños gorilas criados artificialmente. Entre ellos y sus cuidadoras se han creado episodios de juego manipulativo al efecto de que emergieran «formatos de acción conjunta», los cuales son típicos de los niños que se hallan en el mismo nivel de desarrollo. La respuesta de los gorilas ha sido muy pobre. Ha quedado, sin embargo, patente en otros episodios que los pequeños gorilas eran capaces de entender a sus cuidadoras y de hacerse entender de ellas. Esto nos ha llevado a estudiar hasta dónde llega ese «mutuo entendimiento» o capacidad de «compartir significados» atribuibles a estos antropoides. Dado que las acciones comunicativas más notables han ocurrido en situaciones que involucraban la satisfacción de alguna necesidad y también en el juego movido, hemos planteado la relación que existiría entre sistemas motivacionales y acción comunicativa. Nuestra elaboración teórica nos permite desvelar algunos de los prerrequisitos de la función simbólica y de las formas de comunicación más avanzadas que se dan ya entre los niños y no en nuestros gorilas como tampoco probablemente en los demás antropoides.     

A pilot study of performance in young and middle-aged adults on verbal recall

The objective was to explore whether middle-aged adults (M age = 48.9 yr.; n = 26) differed on verbal recall from young adults (M age = 26.3 yr.; n = 26). Little data exist on the performance of middle-aged, healthy adults. Groups of young and middle-aged adults recalled words from the Rey Auditory Verbal Learning Test across six trials during a single session. The same 15 words were used for recall in Trials 1-5. Prior to the sixth trial, 15 distractor words were presented. Participants then recalled the original set of 15 words. No significant differences occurred on any of the recall trials. Although the power of this study was low, the effect of age is apparently quite small.     

A Meta-Analysis of the Convergent Validity of Self-Control Measures

There is extraordinary diversity in how the construct of self-control is operationalized in research studies. We meta-analytically examined evidence of convergent validity among executive function, delay of gratification, and self- and informant-report questionnaire measures of self-control. Overall, measures demonstrated moderate convergence (r_random = .27 [95% CI = .24, .30]; r_fixed = .34 [.33, .35], k = 282 samples, N = 33,564 participants), although there was substantial heterogeneity in the observed correlations. Correlations within and across types of self-control measures were strongest for informant-report questionnaires and weakest for executive function tasks. Questionnaires assessing sensation seeking impulses could be distinguished from questionnaires assessing processes of impulse regulation. We conclude that self-control is a coherent but multidimensional construct best assessed using multiple methods.     

Stereotypes as justifications of prejudice

Three experiments investigate how stereotypes form as justifications for prejudice. The authors created novel content-free prejudices toward unfamiliar social groups using either subliminal (Experiment 1, N = 79) or supraliminal (Experiment 2, N = 105; Experiment 3, N = 130) affective conditioning and measured the consequent endorsement of stereotypes about the groups. Following the stereotype content model, analyses focused on the extent to which stereotypes connoted warmth or competence. Results from all three experiments revealed effects on the warmth dimension but not on the competence dimension: Groups associated with negative affect were stereotyped as comparatively cold (but not comparatively incompetent). These results provide the first evidence that-in the absence of information, interaction, or history of behavioral discrimination-stereotypes develop to justify prejudice.     

The effects of pure pair repetition on younger and older adults' associative memory

Although aging causes relatively minor impairment in recognition memory for components, older adults' ability to remember associations between components is typically significantly compromised, relative to that of younger adults. This pattern could be associated with older adults' relatively intact familiarity, which helps preserve component memory, coupled with a marked decline in recollection, which leads to a decline in associative memory. The purpose of the current study is to explore possible methods that allow older adults to rely on pair familiarity in order to improve their associative memory performance. Participants in 2 experiments were repeatedly presented with either single items or pairings of items prior to a study list so that the items and the pairs were already familiar during the study phase. Pure pair repetition (the effects of pair repetition after the effects of item repetition are taken into account) increased associative memory for older and younger adults. Findings based on remember and know judgments suggest that familiarity but not recollection is involved in mediating the repetition effect.     

Item banks for measuring emotional distress from the Patient-Reported Outcomes Measurement Information System (PROMIS®): depression, anxiety, and anger

The authors report on the development and calibration of item banks for depression, anxiety, and anger as part of the Patient-Reported Outcomes Measurement Information System (PROMIS?). Comprehensive literature searches yielded an initial bank of 1,404 items from 305 instruments. After qualitative item analysis (including focus groups and cognitive interviewing), 168 items (56 for each construct) were written in a first person, past tense format with a 7-day time frame and five response options reflecting frequency. The calibration sample included nearly 15,000 respondents. Final banks of 28, 29, and 29 items were calibrated for depression, anxiety, and anger, respectively, using item response theory. Test information curves showed that the PROMIS item banks provided more information than conventional measures in a range of severity from approximately -1 to +3 standard deviations (with higher scores indicating greater distress). Short forms consisting of seven to eight items provided information comparable to legacy measures containing more items.     

Predictors of recidivism by stalkers: a nine-year follow-up of police contacts

In a subsample of a multisite stalking study (Mohandie, Meloy, McGowan, & Williams, 2006) comprising 78 offenders from one site, 77% committed new offenses within an average follow-up of 106 months (8.8 years). Over half (56%) were charged for new stalking related offenses and 33% for violent recidivism. Violent reoffending, including sexual offenses, was predicted by risk factors consistent with existing literature: younger age at first conviction, prior release failures, and criminal history. Stalking recidivism was predicted by pre-index offending scores, using the Cormier-Lang, and prior diagnosis of a mental illness. In addition, stalkers with previously diagnosed mental illness had significantly more police contacts as complainants than those without; their recidivism was also more likely to be non-violent.
