Don’t look! don’t touch! inhibitory control of eye and hand movements

Inhibitory control of eye and hand movements was compared in the stop-signal task. Subjects moved their eyes to the right or left or pressed keys on the right or left in response to visual stimuli. The stimuli were either central (angle brackets pointing left or right) or peripheral (plus signs turning into Xs left or right of fixation), and the task was either pro (respond on the same side as the stimulus) or anti (respond on the opposite side). Occasionally, a stop signal was presented, which instructed subjects to inhibit their responses to the go stimulus. Stop-signal reaction times (SSRTs) were faster overall for eye movements than for hand movements, and they were affected differently by stimulus conditions (central vs. peripheral) and task (pro vs. anti), suggesting that the eyes and hands are inhibited by different processes operating under similar principles (i.e., a race between stop and go processes).     

Legal proceedings,reforms, and emerging issues in child sexual abuse cases

Criminal and civil proceedings are outlined for cases of intrafamilial child abuse. Statutory reforms and court decisions in the area of sex abuse are reviewed, citing their potential beneficial and harmful effects on both offenders and victims. Finally, the roles of children and mental health experts in court proceedings are discussed.     

Rational-emotive therapy in the therapeutic community

Therapeutic Communities (TC's) have become increasingly popular in the treatment of substance abusing psychotherapy clients. Their popularity appears to have stemmed from the failures of traditional and more individual treatment modalities. Approaches focusing on immeasurable constructs and often irrelevant past events are argued to contribute to symptom maintenance and resistance in this client population. It is argued that a more direct, responsibility-oriented approach be implemented in a systematic and consistent fashion in order to facilitate treatment. The systematic application of Rational-Emotive Therapy in a self-contained therapeutic system is discussed.Raymond J. Yeager Ph.D., is Director of Psychological Services at A.P.P.L.E.

Self-help efforts in a squatter community: Implications for addressing contemporary homelessness

This analysis addresses the nature of contemporary homelessness in the United States, the historical foundations of the shelter system, and survival strategies utilized by homeless persons in meeting their physical, social, and psychological needs. A framework that examines the degree of publicness/privateness and permanency/temporariness of spaces utilized by homeless persons is applied to a case study of a self-help squatter community living on an empty lot in New York City. By looking at the members of the group, their relationship to their neighbors and the local community, and their approaches in dealing with their needs, an assessment is made of this labor-intensive, self-help effort for providing shelter. Implications of self-help approaches are related to policy development and further research.     

Fluency and response speed in recognition judgments

Previous research has suggested that perceptual fluency can contribute to recognition judgments. In this study, we examined whether fluency in recognition is based upon the speed of preceding operations, as suggested by studies of perceptual fluency. Subjects studied items in both lexical decision and naming tasks, and were then tested on two blocks of lexical decision trials with probe recognition trials. Jacoby’s process dissociation procedure was used, and results from this procedure suggested that recognition judgments in the task were based largely upon familiarity. However, the estimated discriminability available from response time distributions was significantly less than the observed recognition discriminability. Simulated memory operating characteristics confirmed this underdetermination of recognition by response times. The results demonstrate, contrary to previous suggestions, that fluency in recognition is not based upon speed.     

A positron emission tomography (PET) study of autobiographical memory retrieval

Memory for the experiences of one's life, autobiographical memory (AM), is one of the most human types of memory, yet comparatively little is known of its neurobiology. A positron emission tomography (PET) study of AM retrieval revealed that the left frontal cortex was significantly active during retrieval (compared to memory control tasks), together with activation in the inferior temporal and occipital lobes in the left hemisphere. We propose that this left frontal lobe activation reflects the operation of control processes that modulate the construction of AMs in posterior neocortical networks.     

A simple,all-mechanical operant apparatus

An apparatus is described that utilizes the force exerted by a rat in turning a wheel to rotate reward cups into his presence after passing through a reservoir containing water or ground mash. The response-ratio requirement, force requirement, and amount of reward can be manipulated by simple adjustment or interchange of parts.
