Assessing Leadership Potential with a Biographical Measure of Personality Traits

The aim of this study was to demonstrate the feasibility of biographical inventories free of the limitations common to many current biographical measures by constructing and validating an inventory composed of homogeneous scales, with item content that is factual and fair, to assess personality traits predictive of leadership. The experimental inventory, with tentative scales for Dominance, Emotional Stability, Need for Achievement, Self-Confidence, and Sociability, was administered to incoming midshipmen at the US Naval Academy and item analyzed. The validity of the final scales was appraised against subsequent peer ratings of the traits and of leadership shortly after entering the Academy; military performance grades, and midshipman rank and leadership position at the Academy; and recommendations for promotion after graduating and serving as an officer. The Sociability, Dominance, and Need for Achievement scales demonstrated convergent and discriminant validity, and all of the scales except Self-Confidence correlated with the leadership criteria. The Sociability scale’s consistent correlations with several of the leadership criteria, including a nontrivial correlation (r = 0.28) with the leadership peer rating, implies that this measure may be useful in assessing leadership potential.     

Further constraints on the bizarreness effect: Elaboration at encoding Bridget Robinson-Riegler

In this study, we attempted to determine why the mnemonic benefit of bizarreness is not found with the use of complex sentences (i.e., those containing additional modifiers of nouns) as stimuli. Several explanations were investigated, including the idea that complexity reduces the imageability of the sentence and the idea that complexity itself is mnemonically beneficial. The results of four experiments favored the latter explanation. We suggest that the cues associated with the complexity of the sentence provide more effective or salient retrieval cues than do those associated with sentence bizarreness. Consequently, the mnemonic benefit of bizarreness appears to occur only with relatively impoverished encoding contexts (e.g., simple, unelaborated sentences).     

Reward dominance among children with disruptive behavior disorders

Investigated was a deficit in avoidance learning in situations of competing rewards and punishments in boys with behavior disorders. This learning style has been found to differentiate adults with psychopathy and controls and has been labeled reward dominance. The present study investigated the reward dominance paradigm in a group of 9- to 13-year-old boys with disruptive behavior disorders (N=21) and a normal control group (N=22). Subjects played four computer games programmed to provide the subject with a steadily decreasing ratio of rewards to punishments. Although the groups did not differ initially on the number of trials played, significant group differences emerged when measures of anxiety were included in the analysis. That is, boys with disruptive behavior disorders played more trials (reward dominance) only when the effect of anxiety was controlled. These findings are consistent with Gray's biobehavioral theory of personality and are also consistent with research indicating that anxiety is an important marker for a distinct subgroup of children with behavior problems.     

Sex-role identity and separation-individuation pathology

The Mahlerian theory of childhood psychological development suggests that the same sex parenting of girls in the mother-child dyad predisposes women to experience specific difficulties in the separation-individuation (S-I) process (Mahler, Pine & Bergman, 1975). Pathological states in adulthood have been attributed to these S-I disturbances (Pine 1979; Kernberg 1980). However, this theory has never been empirically tested. In this study 53 subjects were assessed for adult manifestation of disturbance in the separation-individuation process using a self-report questionnaire (Separation-Individuation Inventory: Christenson & Wilson, 1985), In contrast to previous theoretical work, women showed significantly lower levels of disturbance in the separation-individuation process than did men. Assessment of sex-role identity (Bem Sex Role Inventory: Bem, 1981) showed no significant difference between overall sex-role identity of the male and female subjects. Individuals lacking any clear sex-role identity showed significantly higher levels of disturbance in the separation-individuation process than those with feminine, masculine or androgynous identity. These findings demonstrate the importance of considering sex-role identity as well as biological sex when describing some psychological characteristics and also demonstrate the importance of any sex-role acquisition, whether male or female, for psychological well-being.     

Stimulus fading in the treatment of adipsia

Stimulus fading procedures have repeatedly been demonstrated as effective in shaping a wide variety of new behaviors. Borrowing from this body of research, the behavioral treatment of feeding disorders presents a new area of application for stimulus fading. The purpose of this study is to demonstrate the efficacy of stimulus fading in the treatment of adipsia. Two children who ate solids, but refused all liquids, were participants in the study. Results showed that a five step fading procedure starting with a spoon and thickened liquids, and ending with a cut‐out‐cup, was successful in establishing cup drinking skills for both children. Results of the study suggest that stimulus fading can facilitate feeding skill acquisition. Copyright © 2001 John Wiley & Sons, Ltd.     

Classifying chimpanzee facial expressions using muscle action

The Chimpanzee Facial Action Coding System (ChimpFACS) is an objective, standardized observational tool for measuring facial movement in chimpanzees based on the well-known human Facial Action Coding System (FACS; P. Ekman & W. V. Friesen, 1978). This tool enables direct structural comparisons of facial expressions between humans and chimpanzees in terms of their common underlying musculature. Here the authors provide data on the first application of the ChimpFACS to validate existing categories of chimpanzee facial expressions using discriminant functions analyses. The ChimpFACS validated most existing expression categories (6 of 9) and, where the predicted group memberships were poor, the authors discuss potential problems with ChimpFACS and/or existing categorizations. The authors also report the prototypical movement configurations associated with these 6 expression categories. For all expressions, unique combinations of muscle movements were identified, and these are illustrated as peak intensity prototypical expression configurations. Finally, the authors suggest a potential homology between these prototypical chimpanzee expressions and human expressions based on structural similarities. These results contribute to our understanding of the evolution of emotional communication by suggesting several structural homologies between the facial expressions of chimpanzees and humans and facilitating future research.     

Effects of consumer embarrassment on shopping basket size and value: A study of the millennial consumer

This paper examines how the emotion of embarrassment affects shopping behavior in a retail setting. In a series of three studies, we explore the phenomenon of “masking,” which is defined as a coping strategy used by shoppers when experiencing embarrassment related to a purchase task. Study 1 provides consumer insights into masking behaviors among Millennials. Study 2 empirically examines degrees of anticipated embarrassment associated with purchasing a variety of personal care products and uses a controlled experiment to test the impact of embarrassment on the size of the shopping basket (number of items purchased) and the value of the shopping basket. Study 3 examines basket size and value with respect to complementary and counterbalancing products, and compares Millennial with non‐Millennial consumers. Collectively, this research indicates that both Millennial and non‐Millennials use masking as a coping strategy for a variety of products due to anticipated embarrassment, translating into enhanced basket sizes and values. This effect appears to be moderated by one's innate susceptibility to embarrassment. This study contributes to our understanding of how the emotion of embarrassment influences shopping basket composition in terms of its value and size. It also provides insightful findings relevant to retail practitioners. Copyright © 2014 John Wiley & Sons, Ltd.
