A Survey of Dynamic Principles Governing Memory

A triadic coalition game was structured as an achievement-oriented situation by inclusion of a skill-based game task. Deductions regarding coalition partner choices were derived from Atkinsons' model of achievement motivation with the expectation that achievement-oriented players (Ms < Maf) would prefer moderate-risk strategy options while failure-avoidant players (Maf < Ms) would avoid moderate-risk strategies.

Observation was made of the coalition partner preferences of 126 college sophomore males and females who played the game in same-sex triads. The Ss were categorized into motive configuration groups on the basis of scores derived from the Test of Insight and the Test Anxiety Questionnaire.

The results were supportive of the hypotheses, since the Ms < Maf group chose moderate-risk coalition options more frequently than did the Maf < Ms group. By contrast the Maf < Ms group chose low-risk strategies and tended to avoid moderate-risk coalition options. While other coalition-game studies have shown differences in strategy behavior between males and females, sex differences did not occur in the present game. The lack of sex differences was explained by the high level of concern for winning among members of both sexes generated by the achievement nature of the game task.     

It’s not what you said,it’s how you said it: An analysis of therapist vocal features during psychotherapy

Psychotherapy is a conversation, whereby, at its foundation, many interventions are derived from the therapist talking. Research suggests that the voice can convey a variety of emotional and social information, and individuals may change their voice based on the context and content of the conversation (e.g. talking to a baby or delivering difficult news to patients with cancer). As such, therapists may adjust aspects of their voice throughout a therapy session depending on if they are beginning a therapy session and checking in with a client, conducting more therapeutic ‘work’ or ending the session. In this study, we modelled three vocal features—pitch, energy and rate—with linear and quadratic multilevel models to understand how therapists’ vocal features change throughout a therapy session. We hypothesised that all three vocal features would be best fit with a quadratic function—starting high and more congruent with a conversational voice, decreasing during the middle portions of therapy where more therapeutic interventions were being administered, and increasing again at the end of the session. Results indicated a quadratic model for all three vocal features was superior in fitting the data, as compared to a linear model, suggesting that therapists begin and end therapy using a different style of voice than in the middle of a session.     

The wellness behavior interaction model

A cognitive-behavioral model for conceptualizing wellness is proposed consisting of situational/antecedent variables, person variables, and consequence variables which, taken individually or together, may serve to describe and explain wellness behavior. The model also is interactional in the sense that different categories of variables or factors within a category may impact on each other in a multidirectional fashion. A selective review of research relating to each variable is provided to demonstrate the need for such a multidimensional conceptual scheme for wellness.     

Alcohol and Complex Functioning1

Twenty-five managers participated in two parallel 6-hour quasi-experimental simulations. On placebo treatment days, the subjects received hourly placebo drinks. On alcohol treatment days (order counterbalanced), enough alcohol was provided prior to the fourth hour of simulation participation to attain a breath alcohol level (BAL) of near 0.10. All other drinks contained a placebo beverage. Complex task performance was assessed on five variables derived from complexity theory, comparing performance for three measurement periods: (a) prior to the fourth hour of simulation participation (placebo treatment), (b) during the fourth hour (rising BALs on alcohol treatment days), and (c) during the fifth/sixth hours (falling BALs). Alcohol diminished the participants’ breadth of approach (differentiation). Performance on indicators of strategic functioning (integration) decreased after BALs had begun to fall but not while BALs were rising. The implications for performance of complex tasks under the influence of alcohol and for the applicability of the acute tolerance phenomenon to complex task environments are considered.     

Abstraction and its Limits: Finding Space For Novel Explanation

Several modern accounts of explanation acknowledge the importance of abstraction and idealization for our explanatory practice. However, once we allow a role for abstraction, questions remain. I ask whether the relation between explanations at different theoretical levels should be thought of wholly in terms of abstraction, and argue that changes of the quantities in terms of which we describe a system can lead to novel explanations that are not merely abstractions of some more detailed picture. I use the example of phase transitions as described by statistical mechanics and thermodynamics to illustrate this, and to demonstrate some details of the relationship between abstraction, idealization, and novel explanation.     

Care and Justice Moral Orientation Among African American College Students

The current study assessed the moral orientation of African American college students. In addition, we examined whether or not they exhibit the gender difference in moral orientation hypothesized by Gilligan. One hundred sixty-six African American undergraduates at an historically Black university completed the Moral Orientation Scale, which measures care versus justice moral orientation. The students selected an average of 4.39 care-oriented responses (out of 12). In contrast to predictions that African American culture would lead to the development of a care focus, most participants had a justice focus. In fact, these students were significantly more justice oriented than male law students, who were the most justice oriented of the groups studied by N. Yacker and S. L. Weinberg (1990). There was no evidence of a gender difference in moral orientation. If future research replicates this finding, then Gilligan's theory may need to be modified with regard to African Americans.
