Effects of Expectancy and Attention in Vibrotactile Choice Reaction Time Tasks

The orienting of attention in space has not been considered in the tactile domain. This issue is examined using a modified version of a visual paradigm initially adopted by Posner, Snyder, and Davidson (1980), which manipulates the probability of a stimulus occurring at different spatial locations. Slower RTs at an unexpected stimulus location are thought to reflect the time required to shift attention from the expected to the unexpected location. In two experiments involving vibrotactile choice RT between left and right hands, the two hands were either crossed or uncrossed, and the hands were held both on the left side of the body, both on the right, or one on either side of the midline. There was no evidence to suggest that spatial location (left or right) affected the orienting of attention in the tactual modality. As predicted, RTs were slower when the arms were crossed compared with uncrossed, though this effect was smaller for the expected trials. A coding conflict hypothesis may explain both these findings, but the smaller effect in the expected trials may also reflect attentional factors. Both the relative and absolute location of the hands affected the magnitude of the crossed-arm effect and indicated that attention may play a role in the perceptual division of space into left and right sides. Possible reasons for hand or hemispace asymmetries in different simple and choice RT paradigms were discussed.

Linking Work and Domestic Problems With Police Suicide

We reviewed the records of 134 police officers who had undergone their first fitness-for-duty evaluation at our center. Fifty-five percent admitted to previous suicide attempts. We examined possible contributing factors. A logistic regression model correctly classified 79.1% of subjects as to whether or not they attempted suicide. Results indicated that officers reporting marital problems were 4.8 times more likely to have attempted suicide, and 6.7 times more likely if they had been suspended. Interestingly, complaints of being administratively harassed were associated with a lower likelihood that an officer would attempt suicide. Variance explained due to age, race, gender, and substance use was nonsignificant.     

Family systems consultation with an athletic team: A case study of themes

Abstract

Utilizing family therapy theory and techniques to consult with businesses and other organizations has grown in popularity. In recent years, systems consultation has also been utilized with athletic teams (Schindler-Zimmerman, Washle, & Rotinsky, 1990; Zimmerman & DeVoe, 1993; Zimmennan & Protinsky, 1993; Zimmennan, 1991, 1993). The literature on systems consultation and athletic teams has primarily focused on interventions, guidelines for consulting with athletic teams, common concerns of athletes and specific theories utilized. This article presents themes which emerged from a consultation case study with a university women's athletic team. The themes emerged from videotape analysis using qualitative methodology. This presentation of themes will give the reader a flavor of systemic consultation with athletic teams including typical issues, team structure, and the similarities between families and sports teams.     

Comparing Field Theories

While in broad agreement with many of the observations made by Donnel B. Stern, this essay emphasizes certain differences in how BFT in general and the work of Nino Ferro in particular are seen. These begin with the very meaning of the term, field, and include a less authoritarian view of the analyst's “knowing” the degree to which the analyst's unconscious and subjectivity are implicated in the creation of the field, and the nature and degree of the analyst's unconscious contribution to the creation of the field.     

The Acquisition of Time Properties Associated with a Sequential Motor Skill

Three experiments are reported that examined the relative importance of phasing and duration training in the motor learning of a sequential task. In all three experiments, the task involved knocking down three barriers in a specified order. The Phasing task required the subject to contact each of the barriers in a particular goal time interval, that is, each segment had a particular movement-time goal. The Duration task required the subject to contact the final barrier in a total elapsed-time goal defined by the experimenter. Following training, half of the subjects in each training condition transferred to either a novel Duration or a novel Phasing task. Phasing-trained subjects, compared to Duration-trained subjects, produced equivalent transfer performance on the Duration transfer task but superior performance on the Phasing transfer task. These results suggest that phasing serves as a higher-order source of information for the performer in a sequential motor task. In addition, these experiments complement and extend previous work by Shapiro (1977) and Summers (1975) which demonstrated that learned phasing patterns were not modified despite changes in the overall rate of performing a motor sequence. Our experiments indicate that phasing training increases the performer’s sensitivity to phasing patterns such that novel temporal patterns can be produced when they are well-defined.     

Tender feet and high stepping: Soring in the Tennessee walking horse industry

This paper focuses on the role relationships between owners, trainers, judges, and federal inspectors in the Tennessee walking horse industry and the accommodations they reach in responding to pressures each places on the others. The paper deals with the practice of soring, or blistering, to alter the gait of the animal and its continued practice despite outcry from humane groups, other horsemen, and the federal government. Trainers are subjected to enormous pressures to win, which means they believe they must “sore” their animals. Because this practice is illegal, they must act in a manner contrary to legal mandates while giving firm lip service to supporting antisoring guidelines.

The study method involved unfocused interviews with 4 U.S. Department of Agriculture inspectors, 14 trainers, and 8 owners. No notes or recording material of any kind were present during the interviews, although notes were committed to paper immediately afterward. Because the first author has been a horseman for some years, he approached the trainers, the jargon of horsemen being unfamiliar to the general public. Other interviews and trade journals were gleaned by both authors.
