Developmental aspects of memory for spatial location

The purpose was to show whether or not the encoding of location met criteria defining an automatic process (L. Hasher & R. T. Zacks, 1979, Journal of Experimental Psychology: General, 108, 356-388; 1984, American Psychologist, 39, 1372-1388). Among other criteria, automatic processes are not expected to show developmental changes beyond an early age, to be unrelated to intelligence level, and to be unaffected by instructions. In the first experiment preschool through sixth-grade children were compared on a 40-picturebook task following incidental (remember the names of pictures) or intentional (remember location) instruction. Subjects viewed and named pictures in sets of four, arranged in quadrants in the opened book, and then attempted to recall names of the objects pictured and to relocate pictures on blank pages. In the second experiment, second and sixth graders, college students, elderly persons, and mentally retarded persons were compared on a 60-picturebook task following either incidental or semantic incidental instructions (give the function of objects pictured). Memory for location was invariant across age groups and intelligence level. The only exception was that 3 and 4 year olds were more accurate following intentional instructions. Otherwise there were no differences between intentional and incidental instructions. Semantic instructions resulted in slightly more accurate locations. The results were interpreted as supportive of the Hasher and Zacks' automaticity hypothesis.     

The interplay between feelings and beliefs about condoms as predictors of their use

Objective: Negative feelings about condoms are a key barrier to their use. Using the behavioural affective associations model, we examined the joint effects of affective associations and cognitive beliefs about condoms on condom use.

Design: In Study 1 (N = 97), students completed measures of their affective associations and cognitive beliefs about sex and condoms, sexual activity and condom use. In Study 2 (N = 171), a measure of behavioural intentions and condom selection task were added.

Main outcome measures: Condom use measured in Study 1 as (1) current condom use, and (2) willingness to use condoms; in Study 2 as: (1) behavioural intentions, (2) number of condoms selected.

Results: Affective associations with sex and condoms were behaviour-specific, were directly associated with the respective behaviour, and mediated the relations of cognitive beliefs to behaviour, ps < .05. In Study 2, affective associations were associated with behavioural intentions and the number of condoms selected, ps < .05; cognitive beliefs were indirectly associated with these outcomes through affective associations, indirect effects: ps < .05.

Conclusions: Affective associations are a behaviour-specific and proximal predictor of condom use, mediating the effect of cognitive beliefs, suggesting they may be a particularly viable intervention target.     

Online Argument Between Israeli Jews and Palestinians

Previous research with face‐to‐face groups found that majority–minority theory was a better predictor of argument patterns between Israelis and Palestinians than cultural codes theory ( D. G. Ellis & I. Maoz, 2002; I. Maoz & D. G. Ellis, 2001 ). But, because of the difficulties of organizing face‐to‐face contacts between Israelis and Palestinians (e.g., security, transportation, check points), computer‐mediated communication has taken on increased significance. This paper builds on previous research pertaining to argument between Israeli Jews and Palestinians and extends that work by investigating the effects of communication technologies on argument interactions between these two groups. The most notable finding was the absence of complex argumentative structures that are typically associated with conflict resolution.     

African American Adolescent-Caregiver Relationships in a Weight Loss Trial

Successful family-based weight loss interventions for African American adolescents are rare. Parent-adolescent interactions supporting adoption of healthier nutrition and physical activity practices are not well understood. African American caregivers' and adolescents' perspectives on how they worked together to achieve weight loss need further exploration. This study describes the relationships experienced by adolescents and caregivers during the 6-month, evidence-based FIT Families weight loss trial and explores differences between families whose adolescents were successful and unsuccessful with weight loss. Exit interviews conducted with 136 adolescents (age 12–16 years; BMI percentile ≥95) and their caregivers (primarily mothers) were taped and transcribed verbatim. Content and thematic analysis was conducted to explore differences between groups stratified by weight loss. Five adolescent-caregiver relationship patterns emerged which describe dyads working together, working alone, working against each other; caregiver support and caregiver working on self. When relationship patterns were compared between groups stratified by weight loss, three themes emerged: motivation, support, and persistence. Families that achieved the greatest weight loss referred more often to working together to reach weight loss goals, attributed their success to adolescent self-motivation, with engaged caregiver support which allowed families to persist in change efforts. Family relationships involving adolescent autonomy, engaged parental support, and persistence despite challenges, clustered differently among adolescents who were successful at weight loss compared to those who were not. Interventionists trained to reinforce effective adolescent-parent interactions will advance behavioral interventions for families who have typically benefited least in prior interventions.
