Using self‐monitoring and differential reinforcement of low rates of behavior to decrease repetitive behaviors: A case study

We used a reversal design to evaluate the effects of a self‐monitoring system and differential reinforcement of low rates of behavior on decreasing repetitive body movements in a child with autism. A trial‐based functional analysis revealed that repetitive body movements were maintained by automatic reinforcement. Treatment consisted of teaching the participant to use a self‐monitoring system to monitor the occurrence of repetitive body movements. A stimulus control analysis revealed the self‐monitoring system acquired stimulus control over the repetitive body movements, in that they were more likely to occur in the absence of the system than in its presence. The self‐monitoring system was implemented with a differential reinforcement of low rates of behavior, and their combined effects were evaluated within a reversal design. Repetitive body movements decreased with the implementation of the treatment. The use of self‐monitoring systems to target problem behavior is discussed.     

Intramuscular electrical stimulation of facial muscles in humans and chimpanzees: Duchenne revisited and extended

The pioneering work of Duchenne (1862/1990) was replicated in humans using intramuscular electrical stimulation and extended to another species (Pan troglodytes: chimpanzees) to facilitate comparative facial expression research. Intramuscular electrical stimulation, in contrast to the original surface stimulation, offers the opportunity to activate individual muscles as opposed to groups of muscles. In humans, stimulation resulted in appearance changes in line with Facial Action Coding System (FACS) action units (AUs), and chimpanzee facial musculature displayed functional similarity to human facial musculature. The present results provide objective identification of the muscle substrate of human and chimpanzee facial expressions- data that will be useful in providing a common language to compare the units of human and chimpanzee facial expression.     

The influence of provocateurs' emotion displays on the social information processing of children varying in social adjustment and age

This study examined the effect of provocateurs' emotion displays on first through fourth graders' social information processing (SIP). Rating and nomination sociometric techniques were used to identify rejected-aggressive, rejected-nonaggressive, average-nonaggressive, and popular-nonaggressive groups. Children viewed videotaped ambiguous provocation situations in which provocateurs' emotion displays were varied systematically. After each vignette, children's recall of story details, attribution of intent, and problem-solving responses were obtained. Half of the children were randomly assigned to a condition where they were asked directly about provocateurs' emotions, and the remaining children were not asked about provocateurs' feelings. Results revealed both developmental and social adjustment differences in SIP. In addition, provocateurs' emotion displays and asking versus not asking about those displays influenced multiple aspects of SIP.     

Friendship jealousy in young adolescents: individual differences and links to sex, self-esteem, aggression, and social adjustment

Children's vulnerability to jealousy surrounding their best friends was explored in 2 studies. Study 1 involved 94 adolescents who reported on their friendship jealousy on a newly created measure. Results indicated that the jealousy measure had sound psychometric properties and produced individual differences that were robust over time and free from socially desirable responding. As expected, girls and adolescents with low self-worth reported the greatest friendship jealousy. Study 2 involved 399 young adolescents and extended the measurement of self-report jealousy to a broader age range. In addition, Study 2 included assessments of jealousy provided by friends and other peers. Self- and peer-reported jealousy were only modestly associated and had somewhat distinct correlates. Structural modeling revealed that young adolescents' reputation for friendship jealousy was linked to behaving aggressively and to broader peer adjustment difficulties. Both self- and peer-reported jealousy contributed to loneliness.     

Pancultural self-enhancement

The culture movement challenged the universality of the self-enhancement motive by proposing that the motive is pervasive in individualistic cultures (the West) but absent in collectivistic cultures (the East). The present research posited that Westerners and Easterners use different tactics to achieve the same goal: positive self-regard. Study 1 tested participants from differing cultural backgrounds (the United States vs. Japan), and Study 2 tested participants of differing self-construals (independent vs. interdependent). Americans and independents self-enhanced on individualistic attributes, whereas Japanese and interdependents self-enhanced on collectivistic attributes. Independents regarded individualistic attributes, whereas interdependents regarded collectivistic attributes, as personally important. Attribute importance mediated self-enhancement. Regardless of cultural background or self-construal, people self-enhance on personally important dimensions. Self-enhancement is a universal human motive.     

Reducing Prejudice: Combating Intergroup Biases

Strategies for reducing prejudice may be directed at the traditional, intentional form of prejudice or at more subtle and perhaps less conscious contemporary forms. Whereas the traditional form of prejudice may be reduced by direct educational and attitude-change techniques, contemporary forms may require alternative strategies oriented toward the individual or involving intergroup contact. Individual-oriented techniques can involve leading people who possess contemporary prejudices to discover inconsistencies among their self-images, values, and behaviors; such inconsistencies can arouse negative emotional states (e.g., guilt), which motivate the development of more favorable attitudes. Intergroup strategies can involve structuring intergroup contact to produce more individualized perceptions of the members of the other group, foster personalized interactions between members of the different groups, or redefine group boundaries to create more inclusive, superordinate representations of the groups. Understanding the nature and bases of prejudice can thus guide, theoretically and pragmatically, interventions that can effectively reduce both traditional and contemporary forms of prejudice.     

TEACHING A STUDENT WITH AUTISM TO MAKE VERBAL INITIATIONS: EFFECTS OF A TACTILE PROMPT

This study examined the effects of a tactile prompting device (the Gentle Reminder) as a prompt for a student with autism to make verbal initiations about his play activities. A multiphase multielement design was used to assess the effects of the device in prompting initiations toward an adult in three different play contexts. Follow-up probes were conducted during cooperative learning activities with typically developing peers in the student's regular education class. The results suggest that the device serves as an effective, unobtrusive prompt for verbal initiations during play contexts and during cooperative learning activities.     

Further constraints on the bizarreness effect: Elaboration at encoding Bridget Robinson-Riegler

In this study, we attempted to determine why the mnemonic benefit of bizarreness is not found with the use of complex sentences (i.e., those containing additional modifiers of nouns) as stimuli. Several explanations were investigated, including the idea that complexity reduces the imageability of the sentence and the idea that complexity itself is mnemonically beneficial. The results of four experiments favored the latter explanation. We suggest that the cues associated with the complexity of the sentence provide more effective or salient retrieval cues than do those associated with sentence bizarreness. Consequently, the mnemonic benefit of bizarreness appears to occur only with relatively impoverished encoding contexts (e.g., simple, unelaborated sentences).     

Reward dominance among children with disruptive behavior disorders

Investigated was a deficit in avoidance learning in situations of competing rewards and punishments in boys with behavior disorders. This learning style has been found to differentiate adults with psychopathy and controls and has been labeled reward dominance. The present study investigated the reward dominance paradigm in a group of 9- to 13-year-old boys with disruptive behavior disorders (N=21) and a normal control group (N=22). Subjects played four computer games programmed to provide the subject with a steadily decreasing ratio of rewards to punishments. Although the groups did not differ initially on the number of trials played, significant group differences emerged when measures of anxiety were included in the analysis. That is, boys with disruptive behavior disorders played more trials (reward dominance) only when the effect of anxiety was controlled. These findings are consistent with Gray's biobehavioral theory of personality and are also consistent with research indicating that anxiety is an important marker for a distinct subgroup of children with behavior problems.     

Sex-role identity and separation-individuation pathology

The Mahlerian theory of childhood psychological development suggests that the same sex parenting of girls in the mother-child dyad predisposes women to experience specific difficulties in the separation-individuation (S-I) process (Mahler, Pine & Bergman, 1975). Pathological states in adulthood have been attributed to these S-I disturbances (Pine 1979; Kernberg 1980). However, this theory has never been empirically tested. In this study 53 subjects were assessed for adult manifestation of disturbance in the separation-individuation process using a self-report questionnaire (Separation-Individuation Inventory: Christenson & Wilson, 1985), In contrast to previous theoretical work, women showed significantly lower levels of disturbance in the separation-individuation process than did men. Assessment of sex-role identity (Bem Sex Role Inventory: Bem, 1981) showed no significant difference between overall sex-role identity of the male and female subjects. Individuals lacking any clear sex-role identity showed significantly higher levels of disturbance in the separation-individuation process than those with feminine, masculine or androgynous identity. These findings demonstrate the importance of considering sex-role identity as well as biological sex when describing some psychological characteristics and also demonstrate the importance of any sex-role acquisition, whether male or female, for psychological well-being.
