Performance on a Mirror-Drawing Task by Non-Right-Handers

Left-, mixed-, and right-handed (each n = 10, N = 30) adolescent boys who were classified on the basis of a hand preference inventory performed a mirror-drawing task with a bilateral transfer of a skill paradigm. Participants' hand preference and the magnitude of bilateral transfer of skill were assessed in terms of errors committed and time taken to complete the mirror-drawing task. Mixed-handed participants exhibited significantly less habit interference for mirror drawing, and they performed the task significantly faster than the left-handers did; the group difference was not significant for the frequency of errors committed. These groups did not differ in terms of the magnitude of bilateral transfer of skill; the trend, however, showed that the transfer of skill was minimum in mixed-handers. These findings extend the theory that mixed-handed participants' inability to transfer motor skill from one hand to the other could be attributable to their lack of a clear pattern of lateralization. Their ability to perform well either at initial or later trials may be a function of less interference from their normal motor habits.     

Development of Spatial Language and Cognition in Hindi- and Sanskrit-Medium Schools

This paper describes a study carried out at Varanasi on the development of geocentric spatial cognition with 4–14 year old children of Hindi and Sanskrit medium schools. A number of tasks and procedures were used to assess the spatial frames of reference children used in describing and interpreting spatial displays. Analysis revealed that Sanskrit medium school children used more geocentric language and encoding than Hindi medium school children. The effect of age was significant only for encoding, not for language. Geocentric spatial cognition was significantly linked to fundamental spatial cognitive ability, as measured by Story-Pictorial Embedded Figures Test and Block Designs Test. The stronger expression of geocentric language and geocentric encoding in Sanskrit than Hindi medium school children suggests that the use of the ability can be sharpened by its practice and actualization in day-to-day life. The relationship between language and encoding was found to be of a moderate level suggesting that geocentric cognition is not determined by language alone, but also by other factors present in children’s eco-cultural contexts.     

Ethical ends: Effect of abstract mindsets in ethical decisions for the greater social good

We explore the impact of construal level on decisions involving conflicts between multiple ethical principles. Whereas abstract mindsets are associated with a focus on ethical issues and superordinate concerns, concrete mindsets are associated with financial self-interest. With abstract mindsets, we find that people abide by rather than violate ethical principles when only the self would benefit (single principle) but they violate ethical principles when doing so is a conduit for a greater social good (multiple principles). With concrete mindsets, people violate ethical principles for personal gain with less concern for the impact on the greater social good. Specifically, with abstract mindsets, people were dishonest to secure larger donations (Study 1) and dishonest to make larger (smaller) donations to charities that supported (threatened) the greater social good (Study 2a, Study 2b) whereas with concrete mindsets, people focused more on dishonesty for personal gain (Study 1, Study 2a, Study 2b).     

Screening detoxifying inpatients with substance-related disorders for a major depressive disorder

The Beck Depression Inventory-Fast Screen for Medical Settings (BDI-FS; [Beck, Steer, & Brown, 2000]) and the Mood Module (MM) from the Primary Care Evaluation of Mental Disorders [Spitzer, Williams, Kroenke, Linzer, deGruy, III, Hahn, & Brody, 1995] were used to screen 100 inpatients detoxifying from alcohol, illicit substances, or both for a major depressive disorder (MDD). Receiver operating characteristic (ROC) analyses indicated that both tests were highly and comparably effective in differentiating patients who were and not diagnosed with a MDD; the ROC areas-under-curves for the BDI-FS and MM were, respectively, .87 and .84. A BDI-FS cut-off score of 10 and above had 90% sensitivity and 78% specificity rates, and a MM cut-off score of 7 and above had 90% sensitivity and 72% specificity rates for discriminating patients with and without a MDD. The clinical advantages and disadvantages of both instruments for rapidly screening detoxifying inpatients for clinical depression were discussed.     

A Monte Carlo investigation of conjoint analysis index-of-fit: Goodness of fit,significance and power

Researchers in the field of conjoint analysis know the index-of-fit values worsen as the judgmental error of evaluation increases. This simulation study provides guidelines on the goodness of fit based on distribution of index-of-fit for different conjoint analysis designs. The study design included the following factors: number of profiles, number of attributes, algorithm used and judgmental model used. Critical values are provided for deciding the statistical significance of conjoint analysis results. Using these cumulative distributions, the power of the test used to reject the null hypothesis of random ranking is calculated. The test is found to be quite powerful except for the case of very small residual degrees of freedom.The authors thank the editor, the three reviewers and Ellen Foxman for helpful comments on the paper.

IQ in childhood and the metabolic syndrome in middle age: Extended follow-up of the 1946 British Birth Cohort Study

IQ in early adulthood has been inversely associated with risk of the metabolic syndrome in midlife. We tested this association in the British 1946 birth cohort, which assessed IQ at age eight years and ascertained the metabolic syndrome at age 53 years based on modified (non-fasting blood) ATPIII criteria. Childhood IQ was inversely associated with risk of the metabolic syndrome, but this association was almost entirely mediated by educational attainment and achieved occupational social class. This may be consistent with a pattern where childhood IQ is strongly associated with outcomes that reflect neurological disorder, such as the degenerative dementias, but less so with common chronic physical diseases of ageing.     

For the Win: Risk‐Sensitive Decision‐Making in Teams

Risk‐sensitivity theory predicts that decision‐makers should prefer high‐risk options in high need situations when low‐risk options will not meet these needs. Recent attempts to adopt risk‐sensitivity as a framework for understanding human decision‐making have been promising. However, this research has focused on individual‐level decision‐making, has not examined behavior in naturalistic settings, and has not examined the influence of multiple levels of need on decision‐making under risk. We examined group‐level risk‐sensitive decision‐making in two American football leagues: the National Football League (NFL) and the National College Athletic Association (NCAA) Division I. Play decisions from the 2012 NFL (Study 1; N = 33 944), 2013 NFL (Study 2; N = 34 087), and 2012 NCAA (Study 3; N = 15 250) regular seasons were analyzed. Results demonstrate that teams made risk‐sensitive decisions based on two distinct needs: attaining first downs (a key proximate goal in football) and acquiring points above parity. Evidence for risk‐sensitive decisions was particularly strong when motivational needs were most salient. These findings are the first empirical demonstration of team risk‐sensitivity in a naturalistic organizational setting. Copyright © 2016 John Wiley & Sons, Ltd.     

Effect of Intentional Sentences on Visual Attention to Human and Animal Pictures: Evidence from Eye Movements

This study explored the effect of specific vs. general sentences, describing intentional aspects of humans and animals on visual attention on face and body regions. A picture-sentence verification paradigm was used and eye movements were recorded as subjects looked at displays in the absence of any overt task. Results indicated higher visual attention to the body regions for sentences expressing specific intentional states for human pictures and not for animal pictures. A strong preference to look at the body regions in general was observed compared to the face regions. Results suggest that understanding intentional states of other agents requires focusing visual attention on the body region compared to the face region. The findings are discussed in terms of interaction of intentional states and visual attention.

Factor analysis of the McCarthy scales for groups of white and Mexican-American children

Factor analyses of the McCarthy Scales of Children's Abilities (McCarthy Scales) were performed on separate groups of Anglo (N = 186) and Mexican-American (N = 126) children to determine the comparability of underlying structures and to examine the construct validity of the McCarthy Scales for each ethnic group. The subjects, ranging in age from 5.6 to 7.6 years, were randomly selected from school enrollment rosters and stratified by age, sex, and ethnicity. A principal component analysis produced three factors for the Anglo as well as the Mexican-American groups. Examination of the coefficients of congruence indicated a close similarity among the matching factors. Additionally, the factors which emerged for the Anglos and Mexican-Americans corresponded to the scales constituting the McCarthy Scales. The results of the study provide evidence for the construct validity of the McCarthy Scales for children of two ethnic groups.
