The lateralized effects of concurrent cognitive and motor performance

Subjects were required to simultaneously tap two button switches, at two different distances apart, while at the same time performing a running memory span (RMS) task of either words or faces. Performance on the button-pressing task was assessed in terms of both speed and consistency. When the switches were close together, both of these measures showed leftand right-hand performance to be selectively disrupted by concurrent performance of faces and words memory tasks, respectively. With the switches further apart, selective disruption of the contralateral hand occurred only with thespeed index. Using the consistency index, however, bilateral disruption was observed with both types of RMS tasks. Error and d’ performance on the words and faces RMS tasks was only disrupted by contralateral manual activity. Some implications of these results for neuropsychological models of brain lateralization of function are discussed.     

Predicting integrity with the HEXACO personality model: Use of self‐ and observer reports

Recent research has suggested that a six‐dimensional model of personality called the HEXACO framework may have particular value in organizational settings because of its ability to predict integrity‐related outcomes. In this series of studies, the potential value of the HEXACO factor known as Honesty‐Humility was further examined. First, the empirical distinctness of this construct from the other major dimensions of personality was demonstrated in a high‐stakes personnel selection situation. Second, Honesty‐Humility was found to predict scores on an integrity test and a business ethical decision‐making task beyond the level of prediction that was possible using measures based on a traditional Big Five model of personality. This finding was also observed when Honesty‐Humility was assessed by familiar acquaintances of the target persons. The applicability of the HEXACO model within industrial and organizational psychology was then discussed.     

The IPIP–HEXACO scales: An alternative, public-domain measure of the personality constructs in the HEXACO model

Recently, Lee and Ashton (2004) described the HEXACO Personality Inventory (HEXACO-PI), a new instrument designed to assess the six dimensions observed in lexical studies of personality structure of various languages. Here, we describe the development of an alternative measure of the HEXACO factors and their facets, using the items of the International Personality Item Pool (IPIP). The scales of the resulting IPIP–HEXACO inventory showed satisfactory psychometric properties, as assessed by internal-consistency reliability, convergent and discriminant correlations with the original HEXACO-PI scales, and factor structure. We discuss the potential usefulness of the new IPIP–HEXACO inventory and its strengths and limitations.     

A factor analysis of the most frequently used Korean personality trait adjectives

We tested the cross‐cultural generalizability of personality structure by factor‐analysing self‐ratings of 435 Korean university students on the 406 most frequently used Korean personality trait adjectives. A plot of eigenvalues and a test of factor replicability both suggested a four‐factor solution. The four varimax‐rotated factors showed strong correlations with the first four factors of the Big Five (Extraversion, Agreeableness, Conscientiousness, and Emotional Stability), as measured by markers selected a priori from the pool of 406 adjectives. We also investigated a five‐factor solution, in an attempt to recover an Intellect factor. The five varimax‐rotated factors corresponded closely to the classic Big Five, but with a minor difference in the rotation of the Conscientiousness and Intellect factors. Solutions involving six and seven factors were also investigated, and these solutions produced a Truthfulness factor similar to some previously discovered lexical factors. The results of the study were discussed in relation to the lexical hypothesis and to previous studies of personality structure in East Asian languages. Copyright © 1999 John Wiley & Sons, Ltd.     

Stepparents’ Attachment Orientation,Parental Gatekeeping,and Stepparents’ Affinity-Seeking with Stepchildren

Remarried stepfamilies are a sizable portion of American families; in a 2011 Pew Center survey, 42% of respondents reported at least one stepfamily member. Family clinicians and researchers suggest that stepparents’ ability to develop close bonds with stepchildren may be critical to the well-being of couple and family relationships. Using actor-partner interdependence models to analyze dyadic data from 291 heterosexual remarried stepfamily couples, we explored factors related to stepparents’ efforts to befriend their stepchildren. Specifically, we evaluated how remarried parents’ gatekeeping and stepparents’ perceptions of their attachment orientations were associated with their own and their spouse's perceptions of stepparents’ affinity-seeking behaviors. Securely attached stepparents and stepparents with anxious attachment orientations engaged more frequently in affinity behaviors than did stepparents with avoidant attachment orientations; there was no difference between securely attached and anxious stepparents. Stepparents’ reports of parents’ restrictive gatekeeping were strongly and negatively associated with both stepparents’ and parents’ reports of stepparent affinity-seeking (actor and partner effects). Parents’ reports of their own restrictive gatekeeping were also negatively (but more weakly) associated with parents’ reports of stepparent affinity-seeking. Implications for families, clinicians, and relationship researchers and theorists are discussed.     

Sex,Power, and Money: Prediction from the Dark Triad and Honesty–Humility

Data were collected from two undergraduate student samples to examine (i) the relations of the ‘Dark Triad’ variables (Machiavellianism, Psychopathy, and Narcissism) with the HEXACO personality dimensions, as well as (ii) the ability of the aforementioned characteristics and of the Big Five personality factors to predict outcome variables related to sex, power, and money. Results indicated that the common variance of the Dark Triad was very highly correlated with low Honesty–Humility and that the unique variance of each of the Dark Triad variables also showed theoretically meaningful relations with the other five HEXACO factors. Furthermore, the Dark Triad and Honesty–Humility were strong predictors of three domains of outcome variables—Sex (short‐term mating tendencies and sexual quid pro quos), Power (Social Dominance Orientation and desire for power), and Money (conspicuous consumption and materialism)—that were not well predicted by the dimensions of the Big Five.

The Delay in Visual Reorientation following Exposure to a Change in Direction of Resultant Force on a Human Centrifuge

Errors in reporting a cued target letter appearing among a string of letters more often reflect the mislocation of a letter appearing elsewhere in the string than the intrusion of one not in the string. The current experiment was conducted to determine the representation of letters at the stage at which errors occur. Four letters (from a set of 12 chosen to contain counterpart pairs that were similar physically, phonemically, or both physically and phonemically) appeared in each exposure, with the target letter indicated by a cue in the postexposure mask. Letter strings presented to one group of subjects were flanked on either side by a pound sign (#) to assess the effect of lateral masking on the terminal letter in the string. Physical similarity dictated the pattern of mislocations between counterparts, suggesting a physical rather than phonemic or abstract representation. Lateral masking played no significant role in the difference between intrusions and mislocations.     

The Soteriology of Role-Play in the Bhagavad Gītā

I will here apply the classical Indian model of the dramatic actor as a methodology for interpreting the soteriological psychology of the Bhagavad Gītā, paying special attention to the usefulness of this approach for clarifying K???a's rationale in showing his divine form in Chapter 11. I argue that the Gītā advocates creative role-play as both the means and the end of liberation. Further, while K???a's teachings can be understood in terms of orthodox Hindu soteriologies that have in view an overcoming of the emotions, I argue that K???a looks to transform Arjuna into an ‘athlete of emotion’, much like traditional Indian-based training methods do for theatrical actors.
