Person Perception in Young Children Across Two Cultures

To adult humans, the task of forming an impression of another social being seems effortless and even obligatory. In 2 experiments, we offer the first systematic cross-cultural examination of impression formation in European American and East Asian preschool children. Children across both cultures easily inferred basic personality traits, such as nice and mean, about unfamiliar peers from behavioral information, whether or not they were specifically prompted to do so. Children were able to identify peers they had seen before, to remember the traits associated with these peers, and to anticipate future behaviors consistent with the traits they had attributed. Thus, for basic traits, the ability to make behavior-to-behavior predictions, via an intervening trait inference, is present in young children across diverse cultures.     

A neural basis for the development of inhibitory control

The present study explores the neural basis of the development of inhibitory control by combining functional neuroimaging with a parametric manipulation of a go–nogo paradigm. We demonstrate how the maturation of ventral fronto–striatal circuitry underlies the development of this ability. We used event–related fMRI to examine the effect of interference on neural processes involved in inhibitory control in children and adults. Nogo trials were preceded by either 1, 3 or 5 go trials and then compared to one another. Both children and adults showed an increase in errors with increasing interference. Successful response inhibition was associated with stronger activation of prefrontal and parietal regions for children than for adults. In adults, activation in ventralprefrontal regions increased with increasing interference from go trials. Unlike adults, the circuitry appeared to be maximally activated in children when suppressing a behavioral response regardless of the number of preceding responses. Furthermore, activation in ventral fronto–striatal regions correlated with both age and performance. These findings suggest that immature cognition is more susceptible to interference and this is paralleled by maturational differences in underlying fronto–striatal circuitry.     

The psychophysics of imagery

A series of experiments considers the extent to which the interrelations among subjective magnitudes aroused by images corresponds to those for subjective magnitudes aroused by physical stimuli. In Experiment 1,68 undergraduates typed phrases in response to graded categories regarding the imagined magnitude of lights, sounds, and smells. In Experiment 2,5 undergraduates and, in Experiment 3, 3 graduate students then magnitude estimated the image intensity aroused by each of these stimulus phrases. In Experiments 4 and 5, the same subjects performed cross-modality matches between phrases arousing images for different attributes (light, sound, and smell). Statistical analysis indicates that estimates based on images display many of the same patterns as those based on physical stimuli. The major exception involves sequence effects, present for actual stimuli but not for images.     

Contributions of the Cognitive Approach to Political Psychology

The social cognition tradition has had a strong impact on political psychology scholarship in the last part of the 20th century. The purpose of this essay is to review the contributions of the cognitive approach in helping political psychologists to better understand how citizens think about the world of politics. I consider research concerned with both the mental structure or representation of information about the political world and research concerned with specifying the cognitive processes that produce political judgments and opinion, and conclude that political cognition scholarship has begun to live up to its promise. In the second part of the essay, I suggest a research agenda for the future, pointing to ten directions for extending the political cognition paradigm.     

Women's bar‐related victimization: Refining and testing a conceptual model

A model of bar victimization is proposed that explores the relationships among a woman's exposure to the bar environment (i.e., frequency of going to bars), her intoxication in that setting (i.e., usual number of drinks), and such individual difference factors as her previous history of victimization (childhood sexual abuse, lifetime violence, and previous partner abuse) and personality characteristics (depression, social anxiety, sensation seeking, and hostility). Earlier findings from work in this area suggest that exposure to the bar environment increases a woman's risk for more severe aggression. The data being used to test the proposed model are from a survey of 198 women bar drinkers in western New York State. These women described bar‐related victimization that ranged from verbal aggression (e.g., threats) through severe physical and sexual violence (e.g., assault and rape). Younger age, history of victimization, greater negative affect, and more frequent drinking in bars were predictive of more severe bar‐related victimization during the past year. These findings are discussed in terms of women's risk for victimization in bars and needed areas of future research. Aggr. Behav. 25:349–364, 1999. © 1999 Wiley‐Liss, Inc.     

Expectation of a final cumulative test enhances long-term retention

In the present study, subjects studied lists of words across four experimental conditions: whether (or not) subjects received initial testing for these lists and whether (or not) they were made aware of an upcoming final free-recall test. Initial testing enhanced final-test performance; however, subjects benefited more from initial testing when they also knew they would need to remember the information for a later test. The data suggest that holding an expectation of the final test encouraged the continued processing of study materials following an initial test, affecting the accessibility of these materials at the time of final recall. The results clearly illustrate how an expectation of a cumulative test might influence long-term retention, which may have important implications for educational practice.     

Dimensions of behavior of toddlers entering early intervention: child and family correlates

This study examined the nature and correlates of the behavioral characteristics of a nationally representative sample of 1612 toddlers 18-31 months of age entering Part C early intervention services in the U.S. Factor analysis of 15 items describing child behavior collected as part of an extensive telephone interview of parents yielded four dimensions of behavior: difficult behaviors, lack of persistence, distractible, and withdrawn. Demographic and personal characteristics of the child and family were found to be related to the four behavioral dimensions. Parent reports of behavior of toddlers with fair or poor health or those with communication difficulties were less positive for all behavioral dimensions, suggesting the development of toddler behavioral characteristics is influencing or being influenced by other facets of development.     

Willingness to use microbicides varies by race/ethnicity, experience with prevention products, and partner type.

OBJECTIVE: To investigate women's willingness to use vaginal microbicides to reduce/prevent HIV infection, using measures grounded in the individual, behavioral, and social contexts of sex. DESIGN: A cross-sectional study that enrolled a sample (N = 531) of 18-55 year old Latina, African-American, and White women in the U.S. between October, 2004, and July, 2005. MAIN OUTCOME MEASURES: Willingness to use microbicides and individual- and context-related variables (e.g., demographics, relationship status). RESULTS: Exploratory and confirmatory factor analyses supported a one-dimensional, 8-item scale, with high internal consistency (alpha = .91). Subgroup analyses within the Latina (n = 166), African- American (n = 193), and White sub-samples (n = 172) also supported a unidimensional scale with strong internal validity and high reliability. Race/ethnicity as a contextual factor, a woman's history of using prevention products, and the nature of the sexual partnership were predictive of willingness to use microbicides (R = .41). That is, women with greater frequencies of condom use, a history of spermicide use, and non-main sexual partners had higher predicted Willingness to Use Microbicides scale scores, while White women had lower predicted scores. CONCLUSION: The Willingness to Use Microbicides scale serves as the first psychometrically validated measure of factors related to microbicide acceptability. Developing and implementing psychometrically validated and contextualized microbicide acceptability measures, in an effort to understand microbicide users and circumstances of use, is crucial to both clinical trials and future intervention studies.     

Teaching spontaneous responses to young children with autism

Using a multiple probe design across responses, we demonstrated the effectiveness of intensive intervention in establishing spontaneous verbal responses to 2 3-year-old children with autism with generalization to novel settings involving novel persons. Intervention involved discrete-trial instruction (i.e., repeated instructional opportunities presented in close proximity to high rates of reinforcement), specific prompts, and error correction. Spontaneous responses were defined as specific verbal utterances (e.g., the child says "bless you") following discriminative stimuli that did not involve explicit vocal directives (e.g., adult sneeze). The development of effective interventions to address the social-communicative needs of very young children with autism is discussed.
