Performance Self-Predictions: The Impact of Expectancy Strength and Incentives1

Performance self-predictions represent an individual's anticipated level performance on an upcoming task. This study focused on the accuracy of these predictions, as well as subjective reactions to making them under varying expectancy and incentive conditions. Results indicate that performance-contingent incentives had a positive effect on task performance, but a negative effect on preferences for making performance predictions. Expectancy strength also influenced these predictions, their subjective interpretations, and task performance. Additional results address the role of other task-relevant judgments (e.g., self-assessed ability and intended effort) when predicting one's performance on a task. Implications of these findings for work motivation and judgment accuracy are discussed.     

On the unavoidability of power in child-rearing: Is the language of rights educationally appropriate?

I am indebted to Graham Haydon for his help with the correct English wording of my thoughts.     

Subgroups of autistic children based on social behavior display distinct patterns of brain activity

Two questions were addressed in the present study: (1) Do autistic and normally developing children exhibit regionally specific differences in electroencephalographic (EEG) activity? (2) Do subgroups of autistic children classified according to Wing and Gould's (1979) system which emphasizes degree of social impairment exhibit distinct patterns of EEG activity? Twenty-eight children with autism (5 to 18 years of age) and two groups of normally developing children (one matched on chronological age and the other on receptive language level) participated. EEG was recorded from left and right frontal, temporal, and parietal regions during an alert baseline condition. Compared to normally developing children, autistic children exhibited reduced EEG power in the frontal and temporal regions, but not in the parietal region. Differences were more prominent in the left than the right hemisphere. Furthermore, subgroups of autistic children based on Wing and Gould's system displayed distinct patterns of brain activity. Compared to autistic children classified as “active-but-odd,” “passive” autistic children displayed reduced alpha EEG power in the frontal region.     

Gender and patterns of sexual risk taking in college students

The role that gender plays in influencing the prevalence and patterns of sexual risk taking was examined in 245 college students from two samples (about 60% of whom were White, 20% Asian, 10% Black, and 6% Hispanic). The sexual experiences of these students were analyzed for potential risk associated with type of partners or sexual practices. Consistent with previous findings, males engaged in more risk taking behaviors relevant to partner choice (e.g., more partners and more casual knowledge of partners) and sexual practices (e.g., lower levels of contraceptive use) than females. Gender differences in patterns of risk taking were also found: For females, potentially risky behavior in the partner domain was negatively related to risky behavior in the sexual practice domain, whereas for males, the domains were positively related. The results suggested that males engaged in greater risk taking across many domains, while females compensate for risk in one domain by lower risk in another.     

Counselling in the enterprise culture

The way in which therapeutic models and language have been dravm upon to provide support for concepts of human flexibility and 'human resource development' in the enterprise culture ofthe 1980s and 1990s is described. The use ofhumane managerial rhetoric to mask the practice of increasingly ruthless public and private-sector organisations, and the dilemmas posedfor counsellors operating within these kinds of institutional settings, are examined.     

A classroom demonstration of self-monitoring, reactivity, and interobserver agreement

A brief classroom demonstration designed to introduce students to the concepts of self-monitoring, reactivity, and interobserver agreement is presented. The demonstration provides students with opportunities to monitor their own behavior, record the behavior of others, and calculate interobserver agreement percentages. Results of using the demonstration with students from two classes are presented.
