Human medial temporal-lobe stimulation disrupts both formation and retrieval of recent memories

Disrupting medial temporal-lobe (MTL) activity for less than a second, either during the initial presentation of a complex scene or when it is presented again 1 min later, severely impairs recognition at the second presentation. MTL disruption during both presentation and recognition periods produces further impairment. These results are not consistent with views limiting MTL function solely to encoding or solely to retrieval mechanisms.     

The ‘catchphrase’ approach to attitude measurement

This paper reviews reasons for preferring a short-item format over traditional statement-form questions in the measurement of personality characteristics that underline social attitude patterns. In particular, it is argued that this approach is better able to separate item content from item context. The confusion of attitude position with response artefacts has in the past led to misunderstandings concerning the structure of social attitudes. Wilson-Patterson questionnaires are easy for Ss to complete, show high reliability and construct validity, are relatively free of acquiescence response bias and social desirability effects and are readily for cross-cultural comparisons.     

Streaks in skilled performance

Experiments in golf putting and darts demonstrated that skilled performance is streaky. The tendency for outcome sequences to form streaks was greatest when the task difficulty was such that about half the trials were successful. Mixtures of the two activities were also streaky, even when periodic interruption made the individual components resemble a random Bernoulli process. Formal models of sequence structure revealed that waves in hit rate are associated with the appearance of streaks.     

Parental influences on academic performance in African-American students

We investigated the relationship between parental influences and academic outcomes for African-American students. Secondary data analysis was conducted on the National Survey of Family and Household data set. Multiple regression analysis showed that parenting style (nurture and control) and parental involvement significantly predicted academic outcomes. Research has traditionally focused on the reasons for the failure of African-American students to succeed in school. This study focused on factors that determine success. The problem of negative school outcomes may be alleviated by studying what works to promote school success rather than what does not work for African-American students.     

CHOICE MAKING TO PROMOTE ADAPTIVE BEHAVIOR FOR STUDENTS WITH EMOTIONAL AND BEHAVIORAL CHALLENGES

Two analyses investigated the effects of choice making on the responding of elementary school students with emotional and behavioral challenges. In the first analysis, 2 participants were given choices from menus of academic tasks, all of which were pertinent to their educational objectives in English and spelling, respectively. Reversal designs showed that the choice-making conditions increased task engagement and reduced disruptive behavior for both students. An additional analysis was performed with a 3rd student in an effort to further distinguish the effects of choice making from preference. In this study, one of the no-choice phases was yoked to a previous choice-making condition. This analysis demonstrated that the choice-making condition was superior to baseline and yoked control phases as determined by levels of task engagement and disruptive behavior. The findings of the two analyses contribute information relevant to students with emotional and behavioral disorders, and to a growing literature on the desirable effects of choice making for students with disabilities and challenging behaviors.     

Gender differences in motivations for course selection: Academically talented students in an intensive summer program

This study examines the motivational factors contributing to course selection in a sample of students enrolled in an intensive three-week academic experience for exceptionally talented adolescents. Our sample included 947 gifted adolescents, of whom 3.7% were Black, 73.5% were White, 2.2% Hispanic, 0.1% Native American, 19.8% Asian, and 0.6% categorized themselves as other. Girls and boys selected different types of classes, with course participation falling along traditional gender-stereotyped lines. Boys and girls both performed exceptionally well, and said they chose their course because the subject was interesting, useful for future goals, and challenging. Females more often than males enrolled in classes because they perceived them as challenging, different from usual, not offered at school, and as making them more well-rounded. Males more often than females tended to select classes because they thought they would do well and/or because they viewed these classes as being useful for future schooling or career. However, these gender differences varied by the type of course the students took. The resulting complex picture of students' motivations is discussed in terms of the need to specify both the contexts in which males and females make their academic choices, and the interactive determinants of their motivations.An earlier version of this paper was presented at the Third Annual Esther Katz Rosen Symposium on the Psychological Development of Gifted Children, University of Kansas, Lawrence, Kansas, February 19–20, 1993.     

Counselling students, training counsellors: Quality within quantity

The clash between the opposing needs of financial constraints and an increasingly distressed student population is being widely debated in higher education. A successful attempt to circumvent this dilemma is described. This involved setting up an expanded counselling network with an emphasis on professional service provision, and combining this with the training and professional development of a network of part-time counsellors. Ethical and practical issues are explored in detail, and encouragement is given to other institutions to use a similar model.     

Sex differences in route learning by children.

Differences between men and women have been reported with respect to route-learning, but sex differences in children on these and related tasks have not been found. In this study, 51 children ages 5 to 12 years were required to learn a route on a map to criterion and then asked to recall landmarks on that route. Boys made significantly fewer errors and took less time and fewer trials to reach criterion in learning the route, and girls recalled more landmarks than boys. Significant main effects for age were also noted on all measures of route learning and landmark recall. These results suggest that the patterns of route learning that have been ascribed to women and men are present in girls and boys.     

Children's recall 1 or 2 years after an event.

In Study 1, children were reinterviewed about an event they had taken part in 2 years earlier when they were 6 years old (M.-E. Pipe & J. C. Wilson, 1994). In Study 2, children were reinterviewed about an event in which they had participated 1 year earlier when they were 6 or 9 years of age (S. Gee & M.-E. Pipe, 1995). Interviews were conducted with or without cue items and distractors, as in the original studies. The amount of information reported in free recall decreased over the 1- or 2-year delays, and for 6-year-olds, there was also a small decrease in accuracy of free recall. Reinstating specific cue items in Study 2 maintained recall when attention was drawn to them, but prompting children led to a decrease in accuracy. Whereas information repeated across interviews was highly accurate, information reported for the first time at the long delays was not.
