The influence of task variation and maintenance tasks on the learning and affect of autistic children

Analyses of autistic children's learning and affect have begun to consider the role of antecedent variables, including the manner with which tasks are sequenced within instructional sessions. Within the context of a simultaneous-treatments design, this experiment evaluated autistic children's affect and rate of task acquisition under three experimental conditions. The conditions were (1) a constant task condition in which only one acquisition task was presented per session; (2) a varied-acquisition-task condition, in which 10 acquisition tasks were randomly interspersed throughout each session; and (3) a varied-with-maintenance-task condition, which randomly interspersed 5 acquisition tasks and 5 which had been previously acquired. The results showed significantly more efficient learning under the varied-maintenance condition, with no consistent differences separating the other two conditions. In addition, observers' ratings of the children's affect showed that the most positive judgments were produced by the varied-maintenance condition. The varied-acquisition condition was next while the constant task condition always produced the least favorable ratings. These findings are discussed in relation to the literature on massed versus distributed practice, stimulus variation, and success-induced motivation. The implications for upgrading the treatment and education of handicapped children are also reviewed.     

Modifications induced by neonatal steroids in reproductive organs and behavior of male rats.

Male rats injected on Day 3 neonatally with .01, .1, 1, 10, 100, or 1,000 micrograms of estradiol benzoate (EB), 10,000 microgram of testosterone propionate (TP), or sesame oil were subsequently examined for testicular, penile, and accessory organ development. Sexual behavior was evaluated during therapy with fluoxymesterone (FM) and then with TP. Estradiol benzoate in dosages greater than 1.0 micrograms delayed testicular descent, reduced the size and hormone responsiveness of reproductive organs, and decreased sexual behavior in a dose-dependent manner. The 10,000-microgram dosage of neonatal TP delayed testicular descent and reduced sexual behavior to levels near those of the 10--100 micrograms EB groups, but it produced no significant penile or accessory organ changes. Neither reduced peripheral organ development nor inhibited neonatal testicular secretions fully explain reductions in male behavior following large dosages of neonatal TP. Neonatal androgen may reduce the responsiveness of central nervous system neurons governing male sexual behavior after being converted to estrogen or by directly altering steroid receptor systems.     

IMPROVING THE PEER INTERACTIONS OF STUDENTS WITH EMOTIONAL AND BEHAVIORAL DISORDERS THROUGH SELF-EVALUATION PROCEDURES: A COMPONENT ANALYSIS AND GROUP APPLICATION

We conducted two experiments examining the effects of a self-evaluation package on the peer interactions of students described as emotionally or behaviorally disordered. Experiment 1 assessed the additive effects of various components of a self-evaluation package on the frequency of inappropriate and appropriate peer interactions. The components assessed were rewards alone, rewards plus discussion, and self-evaluation plus rewards. Results showed limited effectiveness when rewards alone and rewards plus discussion were implemented. However, substantial improvements in peer interactions were observed when the self-evaluation component was added. Experiment 2 examined the efficacy and feasibility of the procedures when implemented in a group setting. Students in three classrooms served as participants. Direct observation data collected for 8 of the participants showed the procedures to be effective in improving peer interactions when implemented in a group context.     

CHOICE MAKING TO PROMOTE ADAPTIVE BEHAVIOR FOR STUDENTS WITH EMOTIONAL AND BEHAVIORAL CHALLENGES

Two analyses investigated the effects of choice making on the responding of elementary school students with emotional and behavioral challenges. In the first analysis, 2 participants were given choices from menus of academic tasks, all of which were pertinent to their educational objectives in English and spelling, respectively. Reversal designs showed that the choice-making conditions increased task engagement and reduced disruptive behavior for both students. An additional analysis was performed with a 3rd student in an effort to further distinguish the effects of choice making from preference. In this study, one of the no-choice phases was yoked to a previous choice-making condition. This analysis demonstrated that the choice-making condition was superior to baseline and yoked control phases as determined by levels of task engagement and disruptive behavior. The findings of the two analyses contribute information relevant to students with emotional and behavioral disorders, and to a growing literature on the desirable effects of choice making for students with disabilities and challenging behaviors.     

Embodying the psychological attitude: types of consciousness in the transformation of culture

It is time to reclaim C.G. Jung’s vision of psychology as the foundational science upon which all sciences and institutions would be based, and as the discipline, theory, and practice necessary for fostering humanity’s overall psychocultural development. Jung identified eight distinct ‘types’ of consciousness through which humankind engages its emerging psychological attitude. Jung’s view of psychological development as hingeing on the differentiation of function-attitudes provides the means for understanding not only ourselves and each other, but our society as well. This paper offers an example of such an analysis by focusing on the current conflict within American political culture. The goal is as lofty as it is necessary: the operationalization of Jung’s vision of psychology as the powerful influencer of human cultural evolution that it has the potential to be. The immediate goal is to instigate the first step toward this vision of Jung’s ‘complex psychology’ by stimulating conversations among Jungians about how they can foster that vision, leading them towards taking up roles as ‘citizen therapists’, actively involved in their communities in cultivating greater empathy and the withdrawal of projections in the interest of furthering ‘collective consciousness’.
