Does inversion affect boundary extension for briefly-presented views?

Inverting scenes interferes with visual perception and memory on many tasks. Might scene inversion eliminate boundary extension (BE) for briefly-presented photographs? In Experiment 1, an upright or inverted photograph (133, 258, or 383?ms) was followed by a 258 ms masked interval and a test photograph showing the identical view. Test photographs were rated as “same”, “closer”, or “farther away” (5-point scale). BE was just as great for inverted as upright views at the 133 and 383 ms durations, but surprisingly was greater for inverted views at the 258 ms duration. In Experiment 2, 258-ms views yielded greater BE when the study photographs were always tested in the opposite orientation, indicating that the difference in BE was related to encoding. Results suggest that scene construction beyond the view boundaries occurs rapidly and is not impeded by scene inversion, but that changes in the relative quality of visual details available for upright and inverted views may sometimes yield increased BE for inverted scenes.     

THIS IS NOT B. F. SKINNER'S BEHAVIOR ANALYSIS: A REVIEW OF HAYES,STROSAHL, AND WILSON'S ACCEPTANCE AND COMMITMENT THERAPY

Acceptance and Commitment Therapy (Hayes, Strosahl, & Wilson, 1999) is an important addition to and extension of the growing field of clinical behavior analysis. The book provides a comprehensive introduction to a new therapy that is rooted in functional contextualistic philosophy and a “post-Skinnerian” behavior-analytic theory of verbal behavior. It begins with the assertion that language or verbal processes are at the heart of psychopathology and human suffering and goes on to describe a therapeutic approach that seeks to undermine these verbal processes and facilitate clients' active commitment to value-driven behavior change. Along the way, the book provides a compelling behavior-analytic account of a number of important but neglected issues in behavior analysis, including human suffering, the nature and function of private events, the self, suicide, anxiety, depression, values, responsibility, and commitment. In so doing, the book cogently challenges the unfortunately common but erroneous assertion that behaviorism does not and perhaps cannot address the complexity of the human condition. The present review provides a general overview of the book, summarizes its chapters, and raises a number of questions that might be addressed in future research.
