A principal components analysis of Rorschach aggression and hostility variables

We examined the structure of 9 Rorschach variables related to hostility and aggression (Aggressive Movement, Morbid, Primary Process Aggression, Secondary Process Aggression, Aggressive Content, Aggressive Past, Strong Hostility, Lesser Hostility) in a sample of medical students (N= 225) from the Johns Hopkins Precursors Study (The Johns Hopkins University, 1999). Principal components analysis revealed 2 dimensions accounting for 58% of the total variance. These dimensions extended previous findings for a 2-component model of Rorschach aggressive imagery that had been identified using just 5 or 6 marker variables (Baity & Hilsenroth, 1999; Liebman, Porcerelli, & Abell, 2005). In light of this evidence, we draw an empirical link between the historical research literature and current studies of Rorschach aggression and hostility that helps organize their findings. We also offer suggestions for condensing the array of aggression-related measures to simplify Rorschach aggression scoring.     

An investigation of the determinants of motor contagion in preschool children

The influence of action perception on action execution has been demonstrated by studies of motor contagion in which the observation of an action interferes with the concurrent execution of a different action. The current study extends prior work on the extent of motor contagion in early childhood, a period of development when the effects of action observation on action execution may be particularly salient. During a classroom story reading, children (mean age 4.8 years) were familiarized with two different-colored bears, one of which was used as a seemingly animate hand puppet while the other bear remained lifeless and inanimate. Children then completed a task in which they were instructed to move a stylus on a graphics tablet in the presence of background videos of each bear making horizontal arm movements which had biological (human-moved) or non-biological (machine-moved) origins. Motor contagion was assessed as the variability of stylus movements in the horizontal axis when children were instructed to produce vertical stylus movements. Significant levels of motor contagion were seen when children observed the previously animate bear in the non-biological motion condition and when they observed the previously inanimate bear in the biological motion condition. For future studies of social perception, this finding points to the potential importance of examining mismatches between prior experience with (or knowledge about) a particular agent and the subsequent behavior of that agent in a different context.     

The relationship between visuospatial sketchpad capacity and children's mathematical skills

This study examined the association between visuospatial sketchpad (VSSP) capacity and children's mathematics attainment. The aim of the study was to explore age-related differences in the relationship between the visual and spatial memory subcomponents of the VSSP (Logie, 1995) and a range of mathematical skills. Fifty-one 7- to 8-year-old and fifty-six 9- to 10-year-old primary schoolchildren participated in the study. The Visual Patterns Test and the Block Recall task were employed as VSSP measures. The results revealed a differential pattern of associations between children's visual and spatial working memory abilities and their mathematical skills. In younger children, the Block Recall task predicted mathematics performance, whereas, in the older children, the Visual Patterns Test was a significant predictor of mathematics performance.     

A Meta-Analysis of an Implicit Measure of Personality Functioning: The Mutuality of Autonomy Scale

The Mutuality of Autonomy scale (MA) is a Rorschach variable designed to capture the degree to which individuals mentally represent self and other as mutually autonomous versus pathologically destructive (Urist, 1977). Discussions of the MA's validity found in articles and chapters usually claim good support, which we evaluated by a systematic review and meta-analysis of its construct validity. Overall, in a random effects analysis across 24 samples (N = 1,801) and 91 effect sizes, the MA scale was found to maintain a relationship of r =.20, 95% CI [.16,.25], with relevant validity criteria. We hypothesized that MA summary scores that aggregate more MA response-level data would maintain the strongest relationship with relevant validity criteria. Results supported this hypothesis (aggregated scoring method: r =.24, k = 57, S = 24; nonaggregated scoring methods: r =.15, k = 34, S = 10; p =.039, 2-tailed). Across 7 exploratory moderator analyses, only 1 (criterion method) produced significant results. Criteria derived from the Thematic Apperception Test produced smaller effects than clinician ratings, diagnostic differentiation, and self-attributed characteristics; criteria derived from observer reports produced smaller effects than clinician ratings and self-attributed characteristics. Implications of the study's findings are discussed in terms of both research and clinical work.     

Infant brain responses to felt and observed touch of hands and feet: an MEG study

There is growing interest concerning the ways in which the human body, both one's own and that of others, is represented in the developing human brain. In two experiments with 7‐month‐old infants, we employed advances in infant magnetoencephalography (MEG) brain imaging to address novel questions concerning body representations in early development. Experiment 1 evaluated the spatiotemporal organization of infants’ brain responses to being touched. A punctate touch to infants’ hands and feet produced significant activation in the hand and foot areas of contralateral primary somatosensory cortex as well as in other parietal and frontal areas. Experiment 2 explored infant brain responses to visually perceiving another person's hand or foot being touched. Results showed significant activation in early visual regions and also in regions thought to be involved in multisensory body and self–other processing. Furthermore, observed touch of the hand and foot activated the infant's own primary somatosensory cortex, although less consistently than felt touch. These findings shed light on aspects of early social cognition, including action imitation, which may build, at least in part, on infant neural representations that map equivalences between the bodies of self and other.     

At the intersection of culture and religion: a cultural analysis of religion's implications for secondary control and social affiliation

Religion helps people maintain a sense of control, particularly secondary control-acceptance of and adjustment to difficult situations--and contributes to strengthening social relationships in a religious community. However, little is known about how culture may influence these effects. The current research examined the interaction of culture and religion on secondary control and social affiliation, comparing people from individualistic cultures (e.g., European Americans), who tend to be more motivated toward personal agency, and people from collectivistic cultures (e.g., East Asians), who tend to be more motivated to maintain social relationships. In Study 1, an analysis of online church mission statements showed that U.S. websites contained more themes of secondary control than did Korean websites, whereas Korean websites contained more themes of social affiliation than did U.S. websites. Study 2 showed that experimental priming of religion led to acts of secondary control for European Americans but not Asian Americans. Using daily diary methodology, Study 3 showed that religious coping predicted more secondary control for European Americans but not Koreans, and religious coping predicted more social affiliation for Koreans and European Americans. These findings suggest the importance of understanding sociocultural moderators for the effects of religion.     

The role of age and inhibitory efficiency in working memory processing and storage components

In this study, we examined the extent to which inhibitory efficiency accounted for age-related decline in the processing and storage components of working memory. Older and younger adults performed a sequential task, which served as an index of deletion-type inhibition (the ability to suppress no-longer-relevant information). The reading span task was used to measure working memory components by examining processing accuracy, processing time, and end-word recall of sentences presented. Reduced inhibitory efficiency, which was poorer in older adults, predicted age-related decline in recall, over and above the effects of processing speed. Similar results were observed for processing accuracy, although the age effect in this component was marginal. These results highlight the important role of deletion-type inhibition in explaining age-related decline in working memory performance, particularly in the storage component, and extend previous research by examining this relationship at a componential level.
