Patterns of Natural Language Use: Disclosure, Personality, and Social Integration

When people write about their deepest thoughts and feelings about an emotionally significant event, numerous benefits in many domains (e.g., health, achievement, and well-being) result. As one step in understanding how writing achieves these effects, we have developed a computer program that provides a "fingerprint" of the words people use in writing or in natural settings. Analyses of text samples indicate that particular patterns of word use predict health and also reflect personality styles. We have also discovered that language use in the laboratory writing paradigm is associated with changes in social interactions and language use in the real world. The implications for using computer-based text analysis programs in the development of psychological theory are discussed.     

PROMOTING RECIPROCAL INTERACTIONS VIA PEER INCIDENTAL TEACHING

This study evaluated peer incidental teaching as a strategy for increasing reciprocal peer interactions by children with autism. Three typical preschoolers were trained as peer tutors for 3 young children with autism. During a classroom free-play session, peer tutors used incidental teaching to obtain verbal labels of preferred toys by children with autism. A multiple baseline across the 3 target children showed replicated positive effects of the intervention. Adult supervision and assistance were then faded systematically, with resulting maintenance of increased reciprocal interactions. Multiple measures of the extent and limits of generalization suggested that 1 child increased interactions in free-play periods throughout the day, but none of the children showed increases at lunch. Teacher and peer ratings supported the social validity of positive findings.     

Effects of cocaine and alcohol, alone and in combination, on human learning and performance.

The acute effects of cocaine hydrochloride (4 to 96 mg/70 kg) and alcohol (0 to 1.0 g/kg), administered alone and in combination, were assessed in two experiments with human volunteers responding under a multiple schedule of repeated acquisition and performance of response chains. Subjects were intermittent users of cocaine and regular drinkers who were not cocaine or alcohol dependent. Alcohol was mixed with orange juice and ingested in six drinks within 30 min; cocaine was administered intranasally 45 min after completion of drinking. In each component of the multiple schedule, subjects completed response sequences using three keys of a numeric keypad. In the acquisition component, a new sequence was learned each session. In the performance component, the response sequence always remained the same. Results were consistent in both experiments, despite variations in the order in which the drugs were tested alone and in combination. Alcohol administered alone increased overall percentage of errors and decreased rates of responding in the acquisition component, whereas responding in the performance component generally was unaffected. Cocaine administered alone decreased rates of responding but did not affect accuracy of responding in the acquisition component, and enhanced accuracy of responding without affecting rates of responding in the performance component. The combined doses of cocaine and alcohol attenuated the effects observed with alcohol and cocaine alone. These results suggest that, under the conditions investigated in this study, (a) alcohol produces greater behavioral disruption than cocaine or cocaine-alcohol combinations, (b) cocaine and alcohol each attenuate effects of the other, and (c) such attenuation is most pronounced for cocaine attenuating the disruptive effects of alcohol.     

The Experience of Caregiving Among Mothers of Adults Suffering from Psychotic Disorders: Factors Associated with Their Psychological Distress

To identify correlates of psychological distress among multiple indicators, 99 women with adult children suffering from a psychotic disorder were interviewed. The women, who were recruited through hospitals and self-help groups, represented different socioeconomic levels. A face-to-face standardized interview was conducted, mainly in the participants' homes. Multiple hierarchical regression analysis showed that dimensions of burden and social support were strongly associated with distress reported by the participants. The negative interactions that participants had with their main confidant or spouse constituted a more powerful correlate than their perception of the quality of this relationship. Furthermore, a perception of their own health as poorer is a strong correlate of their distress. Since no control group was studied simultaneously, these results suggest, but do not prove, the presence of differences between mothers of adults with psychotic disorders and other mothers.     

Cross‐cultural differences in emotion suppression in everyday interactions

Previous research suggests that in collectivistic cultures, people tend to suppress their emotions more than in individualistic cultures. Little research, however, has explored cross‐cultural differences in emotion regulation in everyday interactions. Using a daily social interaction method, we examined whether people from collectivistic backgrounds (Chinese exchange students and immigrants from the Moluccas, Indonesia) living in the Netherlands differed from those from individualistic backgrounds (Dutch natives) in emotion suppression during everyday interactions. We also examined whether this depended on their relationship with the interaction partner(s). We found that Chinese participants suppressed positive and negative emotions more than Dutch and Moluccan participants and that this was related to differences in interdependent and independent self‐construal across the samples. We also found that Chinese participants suppressed positive emotions less in interactions with close others, whereas Dutch participants suppressed negative emotions more with non‐close others. No such differences were found for Moluccans. Our findings support the idea that people from collectivistic cultures suppress emotions more than those from individualistic cultures, but they also suggest that this depends on who the interaction partner is. Furthermore, they suggest that emotion suppression may change when people with collectivistic backgrounds have been raised in individualistic cultures.     

IMPACT OF PARENTAL BINGE EATING DISORDER: EXPLORING CHILDREN'S EMOTIONAL/BEHAVIORAL PROBLEMS AND THE QUALITY OF PARENT–CHILD FEEDING INTERACTIONS

This study examines psychopathological problems in children of parents with binge eating disorder (BED), particularly the effect of parental diagnosis on their offspring's psychopathology and the mediating power of the quality of parent–infant feeding interactions. Two hundred parents and their offspring were administered a questionnaire for the assessment of their children's psychopathology at 18 (T1) and 36 (T2) months of age. An observational measure to evaluate feeding interactions was administered at T1. Children with both parents with BED showed the highest affective, anxiety, oppositional/defiant, and autism spectrum problems, but no influence of paternal diagnosis was found on the offspring's psychopathology. Maternal BED had an influence on children's affective and autism spectrum problems, and diagnosis of BED in both parents had an effect on infants’ affective problems. Paternal BED had an effect on oppositional/defiant problems through the quality of father–infant interactions, and maternal BED had an effect on the offspring's affective and anxiety problems through the mediation of mother–infant interactions. These results suggest the importance of intervention programs focusing both on parental psychopathology and on mother–child and father–child feeding interactions in families with parents with BED.
