Infant recognition memory and later intelligence

The present study asked if tests of visual recognition memory during infancy based on differential fixation to novel and previously seen targets are valid predictors of later intelligence for children scoring in the normal to superior range of intelligence. Statistically significant and moderate correlations of .37 and .57 were obtained between infant recognition memory scores obtained at four to seven months and later vocabulary tests of intelligence, for 54 children tested at four and for 39 children seen at seven years, respectively. The coefficients did not vary by sex, and were independent of differences in socio-economic status.     

An Approach to Teaching Ethics Courses in Human Services and Counseling

This article presents multiple facets of a team approach to teaching and facilitating an ethics course for undergraduate human services students and a graduate ethics course for students majoring in counseling. Starting with general points, this article describes a specific, week‐to‐week approach to a 1‐semester course, concluding with sample student evaluative comments and an experienced professor/author's processing of the experience of preparing and teaching this course for many years.     

Improving the interview skills of college students using behavioral skills training

Obtaining a job as a college graduate is partly dependent on interview performance. We used a multiple baseline design across skills to evaluate the effects of behavioral skills training with self‐evaluation for five college students. Training effects were evaluated using simulated interviews as baseline and posttraining assessments. All participants acquired targeted skills, but we observed some individual differences. Participants were satisfied with training outcomes and rated the procedures as acceptable. Furthermore, ratings from university staff who provide interview training indicated that training improved performance across several skills for the majority of participants.     

Differential incidence of procrastination between blue and white-collar workers

The present study compared chronic procrastination tendencies claimed by “whitecollar” working adults (n = 141) with rates reported by Harriott and Ferrari ( 1996) of “blue-collar” working adults (n - 211). Participants completed reliable and valid measures of everyday procrastination tendencies (decisional, arousal, and avoidant), and socio-demographic items at one of several public forums. Results showed no significant difference between classes of working adults on age, gender, marital status, or the number of children, although “white-collar” workers claimed higher levels of education than “blue-collar” workers. “White-collar” workers also reported significantly higher scores on all three forms of chronic procrastination than “blue-collar” workers. It seems that professional employees report procrastination more frequently than unskilled workers. Further research is needed to explore the causes and consequences associated with differences in chronic procrastination by occupational group.     

Self-enhancement and belief perseverance

Belief perseverance—the tendency to make use of invalidated information—is one of social psychology’s most reliable phenomena. Virtually all of the explanations proffered for the effect, as well as the conditions that delimit it, involve the way people think about or explain the discredited feedback. But it seems reasonable to assume that the importance of the feedback for the actor’s self-image would also influence the tendency to persevere on invalidated feedback. From a self-enhancement perspective, one might ask: Why would people persist in negative self-beliefs, especially when the basis for those beliefs has been discredited? In the present study, actors and observers completed a word-identification task and were given bogus success or failure feedback. After success feedback was discredited, actors and observers persevered equally in beliefs about the actor’s abilities. However, following invalidation of failure feedback, actors provided significantly higher performance evaluations than observers, thus exhibiting less perseverance on the negative feedback. These results suggest that the motivation to maintain a relatively favorable self-image may attenuate perseverance when discredited feedback threatens an important aspect of the self-concept.

Typology of violence derived from ratings of severity and provocation

Two exploratory studies examined ratings of the severity of violence of several behaviors. In Study 1, a very consistent ordering of the behaviors by severity was obtained from two groups of participants. The stated justification for the behaviors was manipulated, and both mitigation and aggravation effects were observed. Study 2 found that essentially the same ordering of behaviors could be obtained in a provocation-rating task, and that both the severity ratings and the provocation ratings yielded four interpretable types of violence upon factor analysis: more severe physical (V1), less severe physical (V2), more severe nonphysical (V3), and less severe nonphysical (V4). Individual profiles of severity ratings across these four types yielded two interpretable groupings of participants upon cluster analysis: a violence-sensitive group and a violence-tolerant group. The violence-tolerant group had lower severity ratings for three of the four types of violence. These empirical distinctions help to illuminate what appear to be different meanings of the term violent for different behavior categories and for different individuals.     

Individual differences on speeded cognitive tasks: Comment on Chen,Hale, and Myerson (2007)

Chen, Hale, and Myerson (2007) recently reported a test of the difference engine model (Myerson, Hale, Zheng, Jenkins, & Widaman, 2003). This test evaluated whether the standard deviation (SD) is proportional to the amount of processing—that is, mean reaction time (RT)—in a speeded cognitive task. We show that this evaluation is not a test of the model because its finding is a consequence of relationships in the data. We argue any model structure that produces increasing values of RT as a function of difficulty, with different slopes for different individuals, necessarily produces a correlation between SD and mean RT. We illustrate this with a different model structure—that is, the diffusion model proposed by Ratcliff (1978)—showing that it produces a fan out between fast- and slow-group means and produces the correlation between SD and mean RT that matches the empirical result.
