Evidence for a distributed hierarchy of action representation in the brain

Complex human behavior is organized around temporally distal outcomes. Behavioral studies based on tasks such as normal prehension, multi-step object use and imitation establish the existence of relative hierarchies of motor control. The retrieval errors in apraxia also support the notion of a hierarchical model for representing action in the brain. In this review, three functional brain imaging studies of action observation using the method of repetition suppression are used to identify a putative neural architecture that supports action understanding at the level of kinematics, object centered goals and ultimately, motor outcomes. These results, based on observation, may match a similar functional-anatomic hierarchy for action planning and execution. If this is true, then the findings support a functional-anatomic model that is distributed across a set of interconnected brain areas that are differentially recruited for different aspects of goal-oriented behavior, rather than a homogeneous mirror neuron system for organizing and understanding all behavior.     

Teachers’ burnout, depression, role ambiguity and conflict

The present study investigates issues associated with teachers’ burnout in primary education as related to depression and role conflict–ambiguity. At the time of the study the participants (562 teachers) were working in seventy nine (79) Primary Education State Schools in Greece (Athens and two prefectures in the southern part of the country). The results showed that of the three factors comprising the Burnout inventory (MBI, Maslach and Jackson, MBI: Maslach Burnout Inventory; manual research edition, 1986), (i.e., Emotional exhaustion, Personal accomplishment, Depersonalization) Emotional Exhaustion showed a statistically significant (positive) correlation with the factors that comprise: (a) the Scale of Depression (CES-D: Ensel, in: Lin et al. (eds.) Social support, life events and depression, 1986; Radloff, Applied Psychological Measurement 1: 385–401, 1977) such as Depressed affect, Somatic retarded activity and (b) Degree of Role Conflict (Role Conflict and Role Ambiguity Scale, Rizzo et al., Administrative Science Quarterly, 15:150–163, 1970, adapted in Greek by Koustelios and Kousteliou, Psychological Reports, 82:131–136, 1998); similarly, Positive affect (CES-D) and Degree of Role Clarity (Role Conflict and Role Ambiguity Scale) showed a statistically significant (negative) correlation with the same factor (Emotional exhaustion). Furthermore, a regression analysis performed with Personal accomplishment as the dependent variable showed that the (combined) factors of Role Ambiguity, Positive Affect and Somatic Retarded Activity contributed significantly to the prediction of the dependent variable; A third regression analysis performed with Depersonalization as dependent variable showed that Somatic Retarded Activity, Role Conflict, Positive Affect, Interpersonal Affect and Role Ambiguity contributed significantly to the prediction of this variable. Overall, the results showed that Greek teachers experience low-moderate levels of Burnout, Depression, Role conflict and Role ambiguity.     

Toward an Understanding of “The Sex Game”: The Effects of Gender and Self-Monitoring on Perceptions of Sexuality and Likability in Initial Interactions1

Results of several studies indicate that men attribute more sexual meaning to heterosexual interactions than do women. Based on Abbey's (1982) findings, we hypothesized that males, in comparison to females, would attribute more sexuality to opposite-sex partners. Based on findings from several self-monitoring dating studies, we predicted that high self-monitors would rate their partners and themselves higher on sexuality and likability traits than would low self-monitors. A laboratory study was conducted in which mixed-sex pairs of participants discussed their likes and dislikes about college life. Participants then rated themselves and their opposite-sex partners on a set of sexuality and likability trait adjectives and indicated their interest in getting to know their partner better. Results supported the gender hypotheses, whereas they only partially supported the self-monitoring predictions. The self-monitoring effects on self-ratings of sexuality and partner ratings of likability are used to explain why high self-monitors are more successful than low self-monitors in establishing heterosexual relationships.     

Why do some men misperceive women's sexual intentions more frequently than others do? An application of the confluence model

Although many researchers have documented men's tendency to misperceive women's friendliness as a sign of sexual interest, few have examined individual differences in men's attitudes and past experiences that might predict their likelihood of making these types of misjudgments. We applied an expanded version of Malamuth, Sockloskie, Koss, and Tanaka's (1991) Confluence model to predict frequency of misperception of women's sexual intent with a sample of 356 male college students. Using structural equation modeling, hostile masculinity, impersonal sex, and drinking in dating and sexual situations predicted men's frequency of misperception. Furthermore, the more risk factors men possessed, the more times they misperceived women's sexual intentions. Suggestions are made for theory development and future research incorporating situational as well as personality measures in longitudinal studies.
