Training parents as behavior therapists: A review

The following paper presents theoretical, empirical, and ethical rationales for the training of parents as behavior therapists for their own children. Thirty-four studies, ranging from single case studies to reports on large-scale, multi-family training programs, are critically reviewed, with primary emphasis on the nature and extent of parental involvement and responsibility, and on the level of methodological sophistication. Related papers are cited when appropriate. Further research and areas needing theoretical clarification are suggested, in relation to the future and expansion of this type of therapeutic intervention. In addition the implications of such an approach for both a “systems” model of child therapy and a prevention-oriented model of mental health services are discussed.     

Attentional Tracking in the Perception of Apparent Motion: Evidence from Sequential Blanking Displays

Perception of sequential blanking displays was studied in a series of three experiments investigating factors that influence whether “shadow motion” or “item motion” is seen in a display. In addition to the duration of the blanking interval (BI) itself, three other such factors were identified: the eccentricity at which the display is viewed, the spacing of items in the display, and the type of motion that subjects are instructed to try to see. It is argued that these and other previously reported results are explicable without the need to invoke any kind of visual integration period. Instead, they are interpreted in terms of a first-order system of automatic luminance detectors and a second-order tracking system involving both voluntary and involuntary attention. The relationship of these findings to other recent work in apparent motion and visual attention and to other bistable motion displays is discussed.
