Friendship cliques: a comparison of the motivational traits of lower/upper track algebra students

This project examined the relationships among the motivation and cognitive profiles of adolescent friendship cliques and peripheral (outside the clique group) students in lower and upper track algebra classes. Two hundred and thirty students from two high schools completed a motivation and cognitive engagement instrument as well as a peer group nomination survey form. Twelve teachers were also asked to complete peer group nomination survey forms. This project used socio-metric and correlational techniques based on previous research traditions in exploring friendship and peer group research to examine these relationships. The results were consistent with theoretically driven predictions and extend previous findings of the impact of friendship cliques in lower grade levels to those of adolescents in the high school setting. Future research in adolescent friendship/clique group research is also discussed.     

Getting a tool gives wings: overestimation of tool-related benefits in a motor imagery task and a decision task

Two experiments examine whether people overestimate the benefits provided by tool use in motor tasks. Participants had to move different quantities of objects by hand (two at a time) or with a tool (four at a time). The tool was not within reach so participants had to get it before moving the objects. In Experiment 1, the task was performed in a real and an imagined situation. In Experiment 2, participants had to decide for each quantity, whether they preferred moving the objects by hand or with the tool. Our findings indicated that people perceive tool actions as less costly in terms of movement time than they actually are (Experiment 1) and decide to use a tool even when it objectively provides less time-based benefits than using the hands (Experiment 2). Taken together, the data suggest that people overestimate the benefits provided by tool use.     

Causal powers and preventers: An explanatory account of cue interaction effects in human causal judgement

According to the causal powers theory, all causal relations are understood in terms of causal powers of one thing producing an effect by acting on liability of another thing. Powers can vary in strength, and their operation also depends on the presence of preventers. When an effect occurs, there is a need to account for the occurrence by assigning sufficient strength to produce it to its possible causes. Contingency information is used to estimate strengths of powers and preventers and the extent to which they account for occurrences and nonoccurrences of the outcome. People make causal judgements from contingency information by processes of inference that interpret evidence in terms of this fundamental understanding. From this account it is possible to derive a computational model based on a common set of principles that involve estimating strengths, using these estimates to interpret ambiguous information, and integrating the resultant evidence in a weighted averaging model. It is shown that the model predicts cue interaction effects in human causal judgement, including forward and backward blocking, second and third order backward blocking, forward and backward conditioned inhibition, recovery from overshadowing, superlearning, and backward superlearning.     

Revised reinforcement sensitivity theory: The impact of FFFS and stress on driving

This study investigated the effect of a fear-based personality trait, as conceptualized in Gray’s revised reinforcement sensitivity theory (RST) by the strength of the Fight/Flight/Freeze system (FFFS), on young people’s driving simulator performance under induced psychosocial stress. Seventy-one young drivers completed the Jackson-5 questionnaire of RST traits, followed by a psychosocial stress or relaxation induction procedure (random allocation to groups) and then a city driving simulator task. Some support was found for the hypothesis that higher FFFS sensitivity would result in poorer driving performance under stress, in terms of significantly poorer hazard responses, possibly due to an increased attentional focus on the aversive cues inherent in the stress induction leaving reduced attentional capacity for the driving task. These results suggest that stress may lead to riskier driving behaviour in individuals with fearful RST personality styles.     

Crossing Boundaries: Commentary on Paper by Sarah Hill

This commentary focuses on two aspects of Hill's presentation. First, it addresses the critical role of repetition compulsion in carrying into analytic enactments the patient's early, unsymbolized traumas. This discussion addresses, furthermore, Hill's reference to her early, preverbal, experience with an African nanny, as this resonated with some of the author's personal experiences. It is suggested that, particularly in American culture, the identities of white children who experience extended care by black nannies must be regarded as multiply determined, race being a critical determinant. How this aspect of white identity is negotiated in a culture bounded by established racial dichotomies is regarded as critical to analytic inquiry, regardless of the racial makeup of the analytic dyad.     

Strangers in Paradise: Trevor,Marley, and Me: Reggae Music and the Foreigner Other

The “immigrant” position calls forth a sense of “strangeness” as a constructed Other. What happens when the self is experienced as a limited, hybridized version of the self one might otherwise be, with opportunity to shape one’s identity? Intersubjectivity is conceptualized as a generative, developmental space in which the “I-ness of me” locates fertile ground for such a project. How do analyst and patient negotiate mutual experiences of alienation in a shared culture of origin, as they encounter experiences of foreignness in a foreign land? As with relational spaces, the construct, “immigrant” is positioned as a thing in itself—a transitional space—in which Otherness might be interrogated. The work of crossing boundaries at the meeting points of race and class is discussed, as two Jamaicans, embedded in the power of Reggae music, engage in psychoanalytic, and socio-political “talk.” Or, is it that we dance?
