TRANSITIONS IN CHILDREN'S ROLES AND CAPABILITIES*

Stage theories and empirical studies have concentrated on a few periods of childhood (e.g., age 5 to 7 years) as important times of transition. On the basis of ethnographic suggestions that the age period 8 to 10 years also involves interesting changes, the authors carried out a search of published empirical studies for findings of transitions in capabilities at 8 to 10 years. An annotated bibliography is provided summarizing the studies found in a 5-year period in three journals. The authors discuss possibilities for characterizing the transition at age 8 to 10, as well as how such a transition meshes with the concept of stage.     

Irrelevant differences in the "same"--"different" task

This article examines the effects of irrelevant information on the multidimensional "same"--"different" task. Subjects were instructed to compare two geometric figures with respect to certain attributes but to ignore other attributes in making the "same"--"different" decision. The irrelevant attributes were chosen in such a way that they could not easily be ignored to see how the existence of irrelevant differences would affect the comparison process. As expected, the overall latencies were longer than is usually found in tasks with no irrelevant differences. However, the nature of the comparison process appeared unchanged. The usual finding of a "fast-same" phenomenon persisted even when irrelevant information was present. The similarity of the results in this task to results in the "same"--"different" task with no irrelevant features supports the idea that the same comparison mechanism is used whether or not irrelevant differences are present in the stimulus pairs. The results suggest a more general-purpose comparison mechanism than is usually included in models of this task. Two-process models of visual comparisons are thus ruled out entirely. A modified version of Krueger's noisy-operator theory does appear consistent with the results.     

Schreber'sMemoirs: Myth or personal lamentation

Lucy Bregman's approach to Schreber'sMemoirs is scrutinized and found to be based on a number of fallacious and contradictory assumptions that call her interpretation of the book as personal religious myth into question. A social constructionist approach to mythology maintained by Berger and Luckmann is advanced, suggesting that at best Schreber's work qualifies as a quasi-mythical attempt to explain the source of his personal sociopsychic suffering. The family and interpersonal dynamics of Schreber's quasi-myth are investigated. Similarities to other cases of psychotic quasi-myths are noted and a general relationship between oppressive socialization and psychotic communications is advanced, as well as a specific alternative interpretation of Schreber's work to that proposed by Bregman.Nathan Church, M.S., is currently teaching at Douglass College of Rutgers University, where he is nearing completion of his Ph.D. in sociology.     

Effects of a token reinforcement system on journal reshelving

A token reinforcement program involving two levels of token value and backup reinforcers to increase journal reshelving behavior in a large university library was experimentally evaluated. Results showed that instructions (in which signs asked users to reshelve journals) had no impact. By contrast, token reinforcement contingent on reshelving behavior led to a marked increase in journals reshelved. A return to instructions-only conditions, when data were corrected for library usage, showed an increase in unreshelved journals over the token reinforcement period, though the increase was not to baseline levels. For the next 11 months, library staff maintained a modified token program. Follow-up data collected after that interval showed that number of unreshelved journals remained markedly lower than levels at baseline and the first instructions-only period, though they were slightly higher than at the token reinforcement period. Token reinforcement of the variety employed in this study constitutes an efficient, economical means of changing the behavior of library users who fail to reshelve books and journals.     

Conceptualizing Self-determination from a Behavioral Perspective: The Role of Choice,Self-control,and Self-management

The goal of education can be defined in many ways; but in searching the literature, we found that in most cases, people consider the goal of education to be developing a self-determined individual. Self-determination is an abstract term. Behavior analysts may find this term difficult to define. Therefore, it may be difficult to observe and measure whether “self-determined behaviors” have developed. Many other service providers use this term frequently; thus, behavior analysts working with these service providers must come to terms with this concept in order to better collaborate. We argue that self-determination can be operationally defined with the concepts of choice, self-control, and self-management. By using the measurable behaviors included in these concepts, we believe that services can be developed to teach self-determination skills. This paper explores these concepts and how they can contribute to an operational definition of self-determination, and ultimately, help behavior analysts work with other providers to effectively teach self-determination to individuals with developmental disabilities.

     

Inhibitory control and set shifting describe different pathways from behavioral inhibition to socially anxious behavior

Individuals with a behaviorally inhibited (BI) temperament are more likely to develop social anxiety. However, the mechanisms by which socially anxious behavior emerges from BI are unclear. Variation in different forms of top‐down control, specifically executive functions (EF), may play distinct roles and characterize differential pathways to social anxiety. Here 291 children were assessed for BI in toddlerhood (ages 2 and 3), parent‐reported inhibitory control and set shifting during middle childhood (age 7), and multidimensional assessment of socially anxious behavior completed during late childhood and early adolescence (ages 9 and 12). Structural equation modeling revealed that early variation in BI predicted the development of socially anxious behavior through either higher levels of parent‐reported inhibitory control or lower levels of parent‐reported set shifting. These data reinforce the notion that top‐down control does not uniformly influence relations between temperament and socially anxious behavior. These data suggest novel approaches to thinking about the role of EFs and social anxiety outcomes as children approach adolescence.     

Differential impact of parenting sick infants

Parenting a newborn infant has been identified as a significant stressor, and parenting a sick infant evokes an even greater stress. This study evaluated the differential impact of parenting infants with interrupted infantile apnea vs. extremely low birth weight infants. These infants were compared to normal infants on the Bayley Scales of Infant Assessment and the Parenting Stress Index when the infants were 6 months old. Significant effects on the mental index revealed that the low birthweight infants performed more poorly than did the other groups. A stepwise multiple discriminant analysis on the Parenting Stress Index suggested that child adaptability, maternal restrictions, isolation, and health were significant stressors. Mothers of apneic infants were affected most severely by their child's illness. The lower educational level of these mothers may have influenced these findings.
