Psychophysics of Kinesthesis

A horizontal straight-arm movement was used to determine the relationship between the physical stimulus continuum and the psychological continuum of kinesthetic extent of arm movement. A power function with an exponent of 1.075 best described this relationship. In addition, to classify extent of movement as belonging to either a prothetic or metathetic continuum, the category scale was derived. According to the functional criteria described by Stevens (1957), extent of movement was subserved by a metathetic process which would indicate that, for the present task, judgments were made through the use of positional cues rather than amplitude cues.     

Family assessment: Centripetal and centrifugal family systems

Abstract

A consideration of interactional style is useful to both researchers and clinicians interested in family assessment. This paper offers data and process evaluation scales designed to determine family interactional style, conceptualized as a continuum ranging from centripetal (CP) to centrifugal (CF), and containing at the midpoint a mixed area in which facets of both the CP and the CF styles are found.     

Understanding families as systems

In this article, we discuss recent research that has arisen from theoretical and conceptual models that use a systems metaphor for understanding families. We suggest that research stimulated by such models leads social scientists in new and important directions in understanding the social and emotional development of children in their families. These models view development as resulting from the dynamic transactions across multiple levels of family systems, which regulate a child's behavior. Thus, these models are important in considering multiple influences on development and adaptation.     

Acquisition of matching to sample via mediated transfer

Two severely retarded Down's-syndrome boys learned a matching-to-sample performance through mediated transfer. The transfer paradigm involved three sets of stimuli, one auditory set (A) and two visual sets (B and C). The subjects were taught directly to do B-A and C-B matching, but experienced no direct association between C and A. They acquired the ability to do C-A matching without having been taught that performance directly. They also learned indirectly to name some of the visual stimuli, but naming was apparently not the mediator in the emergent C-A matching. The use of words and letters as stimuli highlighted the possible relevance of mediated associations in the indirect acquisition of elementary reading comprehension and oral reading. The acquisition of matching via mediated transfer also raised some new considerations concerning the role of coding responses in arbitrary matching to sample.     

A Family Affair: Examining the Impact of Parental Infidelity on Children Using a Structural Family Therapy Framework

Infidelity has a permeating impact on social systems, but no system is more impacted by infidelity than the nuclear family. This paper examines the impact of parental infidelity on the family using a structural family therapy (SFT) framework. Conceptualizing and treating infidelity from an SFT approach provides a systemic understanding of how interactions between the parental units about infidelity impact parent–child dynamics. Clinical recommendations are outlined for couple and family therapists to help families find healthy and adaptable ways to create and maintain structures that minimize the harmful impact of infidelity on the family system.     

Disproportionate Representation in Special Education: A Synthesis and Recommendations

Disproportionate representation of minority students in special education remains a very controversial, unresolved issue. This synthesis summarizes historical perspectives and current knowledge about disproportionate representation with respect to: (a) definitions of disproportionate representation and related issues of interpretation; (b) national and state-level estimates of disproportionality for four ethnic groups; (c) legal, policy, research and teacher education responses to disproportionality; and (d) hypothesized causes and predictors of disproportionality. Authors stress the need for: coherent and well-articulated conceptual frameworks, responsible use and representation of data, research dialog that is informed by appreciation of the complex sociopolitical history and current context, and the need for effective advocacy to improve the educational success of minority students.
