Teacher practices as predictors of children's classroom social preference

Students who do not get along with their peers are at elevated risk for academic disengagement and school failure. Research has predominantly focused on factors within such children that contribute to their peer problems. This study considers whether teacher practices also predict social preference for children in that classroom. Participants were 26 elementary school teachers and 490 students in their classrooms followed for one school year. Results suggested that teachers who favored the most academically talented students in the fall had classrooms where children had lower average social preference in the spring after statistical control of children's fall social preference and externalizing behavior problems. Teachers who demonstrated emotionally supportive relationships with students in the fall had classrooms where children had greater possibility of changing their social preference from fall to spring. Although children with high externalizing behaviors tended to experience declining social preference over the course of the school year, teachers' learner-centered practices attenuated this progression. However, teachers' favoring of the most academically talented accentuated the negative relation between externalizing behaviors and social preference. Implications for school psychology practitioners are discussed.     

Heterogeneity in memory training improvement among older adults: A latent class analysis

This study investigated the extent to which older adults' associative memory functioning can be modified through instruction and practice based on individuals' memory status. Here 42 younger adults and 42 older adults performed four tasks that measured strategic and binding aspects of memory. With latent class analysis, two classes of older adults were identified. The first class showed higher memory functioning similar to younger adults, while the second class was characterised by lower memory functioning. A subsequent analysis examined whether the high- and low-performing older adults differ in patterns of gain from receiving instruction and practice on a mnemonic strategy. The results revealed that high-performing older adults, similar to younger adults, showed higher associative memory performance under explicit intentional encoding instruction and after extensive practice of the strategy. In contrast, low-performing older adults benefited more from directed instruction of the strategy. The results are discussed in relation to individual differences in the functional status of mechanisms underlying memory functioning, and how these differences may lead to compensation or magnification of training gain. The present findings highlight the importance of considering differential memory processes to develop specific training paradigms that target the processes that show the most prominent decline.     

Linking Adult Attachment Styles to Relationship Satisfaction in Hong Kong and the United States: The Mediating Role of Personal and Structural Commitment

Maintaining a satisfying heterosexual relationship is important to many individuals?? happiness and physical health. Evolutionary theories on the formation of relationships suggest that adult attachment and relationship commitment are universal mechanisms for securing and maintaining such mating relationships. This study sought to understand how these two mechanisms may link to each other and how they in turn contribute to relationship satisfaction with one??s current partner in Hong Kong Chinese and American cultures. Similarities in the model for relationship satisfaction were found among young dating couples in the United States and Hong Kong. Specifically, attachment anxiety was positively linked to structural commitment, whereas attachment avoidance was negatively related to personal commitment. Both dimensions of attachment (anxiety and avoidance) and both components of commitment (personal and structural) were found to predict current relationship satisfaction significantly and equivalently across cultures, with the pathway from attachment avoidance to current relationship satisfaction similarly mediated by personal commitment in both cultural groups. These results were interpreted in terms of a probable universal logic informing the interpersonal dynamics involving attachment and relationship commitment.     

Sensitivity to event timing in regular and irregular sequences: Influences of musical skill

In two experiments, the performance of listeners with different amounts of musical training (high skill, low skill) was examined in a two-alternative forced choice time-detection task involving simple five-cycle acoustic sequences. In each of a series of trials, all listeners determined which of two pattern cycles contained a small time change. Sequence context was also varied (regular vs. irregular timing). In Experiment 1, in which context was manipulated as a between-subjects variable, high-skill listeners performed significantly better than low-skill listeners only with regular patterns. In Experiment 2, in which context was manipulated as a within-subjects variable, the only significant source of variance was pattern context: All listeners were better at detecting time changes in regular than in irregular patterns. The results are considered in light of several hypotheses, including the expectancy/contrast model (Jones & Boltz, 1989).     

Cultural differences in gender role attitudes between Chinese and American students

A total of 665 Chinese college students in Taiwan and Caucasian college students in eastern North Carolina were administered several sex role attitude scales developed by Spence et al. (1978, 1980). The scales were translated into Chinese for Chinese subjects. Results indicated cultural differences in attitudes toward Marital Roles, Expressivity, Social Interaction, and Preference for males. In both cultures, females were found to be significantly more liberal, as shown in Attitudes Toward Women, Marital Roles, and Social Interaction. These results are consistent with previous research. Cultural differences were also as expected, with Chinese holding more conservative views.An earlier version of this paper was presented in part at the 63rd Annual Convention of the Eastern Psychological Association, Boston, Massachusetts, April 3, 1992.     

The coordination of compensatory tracking and anticipatory timing tasks

Two experiments investigated the presence of a coordination factor in a task consisting of compensatory tracking and anticipatory timing components. The task (Intercept task) resembles a computer game in which a rocket must be aimed and fired to shoot an incoming missile. The studies were designed to determine if a coordinating ability exists above and beyond the abilities needed to perform the component tasks alone. We also investigated the nature of coordination abilities through correlations with other types of coordination tasks and measures of intelligence. Is coordination a general cognitive ability that contributes to performance in a wide range of coordination tasks, or is coordination ability task specific? Multiple regression analyses indicated the existence of a coordination ability in the Intercept task. This coordination ability, however, was shown to be unrelated to the coordination of visual and linguistic processing and to psychometric measures of intelligence as assessed by the Armed Services Vocational Aptitude Battery (ASVAB). Coordination of visual and linguistic processing correlated with a component of the ASVAB measuring perceptual speed. We conclude that, although the ability to integrate separate components of a complex task draws on a coordination ability, this ability is domain specific and thus varies depending on the nature of the component tasks.     

The Moderating Role of Verbal Aggression on the Relationship Between Parental Feedback and Peer Status Among Children with ADHD

We examined associations between children's sociometric status and (a) observed parental feedback as well as (b) child aggression. Participants were 94 children ages 6-10 (64 male; 44 with ADHD) and their parents. Children's peer status, parental feedback to their children, and child aggression were all assessed during lab-based playgroups of four children and their parents. Parent criticism in front of the child's peers was associated with the child receiving more negative ("disliked") and fewer positive ("liked") nominations, but only for children who displayed aggression; this interaction applied almost exclusively to children with ADHD. Parent praise in front of peers was associated with fewer negative nominations when children displayed low levels of aggression, but more at higher levels. Additional analyses revealed that relationships did not exist in the full sample between privately-given parental feedback and children's peer status. Processes by which peers use overheard adult feedback to inform their assessments of children are discussed.     

Operant conditioning of an in vitro CNS-pneumostome preparation of Lymnaea

Operant conditioning of aerial respiratory behaviour and its consolidation into long-term memory in Lymnaea has been previously studied in both intact, freely moving snails and in in vitro preparations made from previously trained snails. Here, we show in previously untrained semi-intact in vitro Lymnaea preparations that aerial respiratory behaviour can also be operantly conditioned. Neither yoked control nor 'run-down' control procedures in these in vitro preparations result in an alteration of aerial respiratory behaviour. Memory in the operantly trained semi-intact preparations persists for at least 1h after training. Intracellular recordings made from RPeD1, one of the 3-CPG neurons and the neuron that initiates CPG activity; show that there are specific changes in central excitatory input to this neuron concurrent with learning and its consolidation into memory. In addition following the acquisition of learning and its consolidation into memory the ability of RPeD1 and VI/J neurons when depolarized to cause a pneumostome opening is significantly decreased. Thus, previously untrained in vitro semi-intact preparations can be used to study changes in neuronal activity in a neuron known to be both necessary for the behaviour and for memory formation.
