Cross-informant consistency in externalizing and internalizing problems in early adolescence

The concept of cross-informant consistency has long been a topic of interest for those involved in assessment of behavior problems in adolescence. The purpose of the present study was to replicate and expand the existing literature by including four informants (mother, father, teacher, and adolescent self-report) and examining correlations among them as well as differences between reporters on an absolute level of both internalizing and externalizing problems. Fifty-two young adolescents (ranging in age from 11 to 15 years) and their mothers, fathers, and social studies teachers participated in the study. The Conduct Disorder subscale, Socialized Aggression subscale, and Anxiety/Withdrawal subscale of the Revised Behavior Problem Checklist were used. Results indicated that teachers showed little agreement with other informants on conduct problems (teachers reporting fewer problems), while parents and adolescents showed significant agreement. Informants showed no agreement on the measure of covert problems (socialized aggression), and all reports showed agreement on internalizing problems (although teachers continued to report fewer problems). Implications for assessment of young adolescents are discussed.This research was supported, in part, by the William T. Grant Foundation and the University of Georgia's Institute for Behavior Research.     

A comparative analysis of two community stressors' long-term mental health effects

The investigation directly compared the long-term mental health consequences of two community-wide stressors, the Three Mile Island (TMI) nuclear accident and widespread unemployment due to layoff, in demographically comparable samples of women. Results showed a marked degree of similarity in the stressors' effects: Levels of subclinical symptomatology were elevated to similar degrees in each sample during the year following stressor onset, and symptom levels remained elevated in each sample 2 to 3 1/2 years later. Moreover, variables identified as predictors of enduring psychological distress were virtually identical for the two samples. Additional analyses revealed that the mental health status of unemployed husbands mediated the negative psychological effects of layoff on their wives. Implications of these results for understanding the long-term consequences of exposure to community-wide stress are discussed.     

Semantic and spatial factors in environmental memory

Reaction time (RT) in simple categorization tasks was predicted to vary as a function of the relatedness among environmental items. Differences in RT were interpreted as reflecting differences in proximity or strength of associations in environmental memory. In Experiment 1, subjects sorted names of familiar local buildings according to which seemed to go together. Hierarchical cluster analysis revealed major clusters whose members were related in function and, within these, smaller clusters of buildings related by spatial proximity. In Experiment 2, subjects responded “Yes” if two items on a trial were both local buildings and “No” if one item was local and one nonlocal. Subjects responded significantly faster to pairs taken from the cluster analysis that were related by both spatial proximity and function than they did to unrelated pairs or pairs related in function only. In Experiment 3, a free-associaton task identified related pairs of spatially proximate, functionally dissimilar environmental items. In Experiment 4, RTs to these pairs did not differ from RTs to pairs of spatially proximate, functionally dissimilar items or from RTs to pairs unrelated functionally and spatially. Spatial proximity and functional similarity together contribute to the organization in memory of buildings in the physical environment.     

The nature of interparental conflict of married and divorced parents: Implications for young adolescents

While research has demonstrated that interparental conflict is associated with poor child and adolescent functioning, studies have not yet addressed the characteristics of such conflict. The purpose of this study was twofold: (1) to report reliability and validity data of a questionnaire, the Interparental Conflict Questionnaire (ICQ), designed to assess the nature of interparental conflict more thoroughly than has been done previously, and (2) to compare the nature of such conflict in a married and divorced sample. Fifty-five married and 46 divorced parents, all of whom had a young adolescent, participated by completing two questionnaires: the O'Leary-Porter Scale and the ICQ. Validity (e.g., correlation with the O'Leary-Porter Scale) was generally acceptable for the ICQ, whereas test-retest reliability tended to be moderate to low. Additional findings indicated that heated arguments rarely occurred. Furthermore, in comparing married and divorced parents, the former discussed issues more and, to some extent, the latter argued more. However, one of the most striking aspects of the findings was the similarity of the married and divorced samples in terms of their conflict. Implications of the findings for understanding and explaining the role of interparental conflict in child and adolescent functioning are explored.This study was supported, in part, by the William T. Grant Foundation and the University of Georgia's Institute for Behavioral Research.     

Phencyclidine discrimination in the pigeon using color tracking under second-order schedules

Pigeons were trained to track different key colors, depending on whether they had been injected with phencyclidine or saline prior to the session. A second-order schedule was used to generate large numbers of responses prior to the initial food delivery. The procedure offers several advantages over traditional procedures for studying drug discrimination.     

Errors and error detection in typing

The errors and error detections made by qualified and trainee typists were examined, when they were given a passage of prose that included pseudo-words and words made up of random consonants. It was shown that trainees make more and detect relatively fewer errors. For all typists errors are made more often per letter in long or degraded words and are relatively less likely to be detected.     

Application of a Temporal Persistence Model to Community Residents' L]ong-Term Beliefs about the Three Mile island Nuclear Accident1

Little is known about the conditions under which beliefs and attitudes about an issue or event will persist over time. The present research took advantage of a “natural experiment”, namely, the Three Mile Island (TMI) nuclear accident, in order (a) better to understand the nature of individuals' b]eliefs about a major event to which they were exposed and (b) to evaluate a conceptual formulation developed from laboratory-based experimental literature concerning when beliefs and attitudes are likely to be temporally persistent. Data were collected over a 3-year period following the accident from two samples of community residents: mothers of young children who lived within a 10-mile radius of TMI and TMI nuclear power plant employees. Samples of mothers and workers from a western Pennsylvania comparison site were also included in the study design. Results supported the persistence model in several respects. First, TMI subjects' b]eliefs, although more extreme than comparison subjects' v]iews, showed virtually no change during the study period. Second, the factors that the model suggests should account for the observed persistence were indeed consistently important predictors of TMI subjects' b]eliefs over time. Implications of the results for future applied work on long-term reactions to major events are discussed.     

故事情景下儿童回答问题的反应倾向

本研究选取5、6、8、10岁儿童各32名,采用故事情景来考察儿童处于不可回答问题情况下猜测答案的倾向.研究结果表明:(1)5～10岁儿童在故事情景下面对不可回答问题时存在猜测答案的倾向,且年龄差异不显著.(2)问题形式对儿童猜测答案的倾向有显著影响,较不可回答的开放问题,儿童在不可回答的封闭问题上的猜测答案倾向更强烈.(3)在不可回答的封闭问题上,儿童倾向给出否定的答案.
