Justification of interpersonal aggression in Japanese,American, and Spanish students

Six hundred and thirty‐two university students of both sexes—242 Japanese (137 males and 105 females), 190 Spanish (71 males and 119 females), and 200 American (100 males and 100 females)—completed a questionnaire that examined their attitudes toward various kinds of aggression directed at other people in different situations that ranged from self‐defense to a method of overcoming communication problems. Factor analysis revealed three factors: physical aggression (killing, torture, and hitting), direct verbal aggression (shouting and rage), and indirect verbal aggression (being ironic and hindering). The basic factor structure of the Japanese, the Spanish, and the USA samples was similar. In all samples, men showed a higher justification of physical aggressive acts in any situation and of indirect verbal aggression in nondefensive circumstances. Cultural differences were found in the degree of justification of the three factors: in all kinds of situations, Japanese students showed a lower justification of indirect verbal aggression but a higher justification of direct verbal aggression than USA and Spain samples. Physical aggression in defensive situations is justified more by Americans than by Japanese and Spanish students. These findings suggest the existence of a common basic moral code about physical aggressive acts, but there seems to be a cultural influence on moral codes concerning verbal aggressive acts. Oriental cultures, with an interdependent construal of self, seem to be more permissive of direct verbal aggression compared with Western cultures, but they have less tolerance for indirect verbal aggression. There were practically no significant differences between American and Spanish scores. Aggr. Behav. 25:185–195, 1999. © 1999 Wiley‐Liss, Inc.     

Sexual Content on Mainstream TV Advertising: A Cross-cultural Comparison

A content analysis of 1,785 American ads and 1,467 Israeli ads maps the representation of sexual content on mainstream TV advertising in the two countries. This content appears in less than 5% of the advertisements. Most of it is mild and portrayed in the conservative context of an established relationship. Explicit material, socially discouraged practices, references to sexual responsibility and complete nudity are extremely rare. Israeli advertisements tend to present a higher share of sexual content than American ads, and male models are more likely to be partially nude than female models—but these differences are minor in extent.     

Does experienced pain affects local brain volumes? Insights from a clinical acute pain model

Background/Objective:To study pain-brain morphometry associations as a function of post-surgery stages (anesthesia, pain and analgesia) in an acute pain model. Method:Impacted mandible third molar were extracted. Before surgery, an anatomical T1 scan was obtained. Regional brain volumen and subcortical nuclei shapes were obtained. Statistical analyses were done using multiple regression, being pain scores the predictors and voxel volumes, subcortical nuclei volumes and subcortical nuclei shapes, the outcomes. Results:Pain was significantly larger at pain than at anesthesia and analgesia stages, and was higher during anesthesia than during analgesia. Pain intensity was related to grey matter in several cortical (Insula, Mid Frontal and Temporal Gyruses, Precuneus, Anterior Cingulate), and subcortical nuclei (Hippocampus, Thalamus, Putamen, Amygdala), depending of the post-surgical stage. A larger number of brain areas showed significance at pain that at anesthesia and analgesia stages. Conclusions:The relationships of regional brain volumes and subcortical nuclei shapes with pain scores seemed to be unsteady, as they changed with the patient's actual pain stage.     

Cross-Cultural Generalizability of CBCL Syndromes Across Three Continents: From the USA and Holland to Australia

The study asked how well Achenbach's 8-factor cross-informant model for the Child Behavior Checklist (Achenbach, 1991a, 1991b, 1991c) fits clinic data in the USA, Holland, and Australia. DeGroot et al.'s Dutch 8-factor model (DeGroot, Koot, & Verhulst 1994) was also tested for its cross-cultural generalizability. Achenbach's matched clinical sample data (N = 2110) were analyzed and contrasted with the previously reported Dutch findings (N = 2335), as well as a new data set collected on clinic referred children and adolescents in Australia (N = 2237). Confirmatory factor analyses supported the Dutch as much as the American model in the USA, Holland, and Australia. Although about 90% of items showed convergent validity across models and countries, the attention and especially the social problems factor found least support. Most double loadings in the current models were not upheld. Instead, additional analyses discovered a number of unmodelled loadings including many cross-loadings. This led to the redefinition of the social problems factor as a mean aggression factor (with associated social problems) whereas the original aggression factor focuses on emotional acting out and the delinquent factor describes an evasive, covert type of antisocial behavior. Overall most support was obtained for the withdrawn, somatic, anxious/depressed, thought problems, and aggressive factors.     

Manual reaction time to linguistic stimuli in child stutterers and nonstutterers

Ten stuttering and ten nonstuttering children, ages 4–8 yr, served as subjects for a motor reaction task to simple and complex linguistic stimuli. The subjects reacted by pressing one of four panels on a touch-sensitive board that depicted the appropriate semantic relationship in response to 30 simple and complex linguistic stimuli. There was a significant increase in the reaction time of both groups with increasing linguistic complexity. No significant differences were found in the reaction time between the two groups, nor in the interaction between group and complexity. Implications regarding linguistic processing are discussed, and an “overload” hypothesis of stuttering is dispelled. It is concluded that stutterers and nonstutterers in this study did not differ in their reaction time nor in their processing time of linguistic material.     

Are mothers of stutterers different? An investigation of social-communicative integration

Many speech-language pathologists assume that parent-child communicative interactions are critical precipitating or maintaining factors in the onset and development of stuttering. Although parents are frequently counseled to alter their attitudes or behaviors, no studies have pinpointed specific parental behaviors as increasing children's disfluency. The purpose of this study was to analyze differences between 12 mothers of stutterers and 12 mothers of nonstutterers in their social-communicative interactions with their own child, an unfamiliar stutterer, and an unfamiliar nonstutterer. Ten minutes of free-play interaction between each mother and child were video recorded from behind a one-way mirror. Results indicate that the two groups of mothers differed significantly only in their use of routine statements. Other findings indicate that stuttering children used significantly more positive and imperative statements than nonstuttering children. All children asked significantly more questions of their own mothers than of unfamiliar mothers.     

Cognitive processing and cognitive ability: A multivariate validity investigation

What are the underlying sources of cognitive ability differences and of cognitive growth? Recent attention has focused on the experimental isolation of cognitive processing factors in the explanation of performance differences on complex tasks, and a number of research studies show a substantial relation between processing parameters and ability differences. Several validity issues—convergent process measures, differential ability prediction, and multiple levels of analysis—have not been addressed empirically, and these concerns are the focus of this study. Sixty eighth graders (30 F, 30 M) and 60 adults (30 F, 30 M) participated in verbal and spatial assessments, and in six experiments over two sessions. Three experiments were designed to estimate memory retrieval processing and three to estimate mental rotation processing. Two strategy parameters were derived also from these experiments. Within the processing tasks, there was modest convergence for eighth graders but negligible convergence for adults. More importantly, relationships between the processing parameters and the ability indices failed substantially to conform to the theoretically predicted convergent/discriminant pattern. Regression analyses also provided support for these disconforming patterns. The viability of explaining developmental and/or individual] differences using cognitive processing variance is explored.     

Differences in intelligence and automatic memory processes

Intelligence-related differences in memory have been viewed as dependent upon control rather than structural memory processes. A test of this notion was made by comparing retarded and nonretarded persons on a subject-paced continuous recognition memory task which was judged to be nonstrategic. The stimuli were computer-generated faces and words. Analyses of pacing rates and posttest interviews provided no consistent evidence for strategy use. Differences in memory between the retarded and nonretarded subjects were attributed to differences in automatic aspects of encoding.
