Why not be a desertist?

On the dimensionality of the Dispositional Hope Scale

The Dispositional Hope Scale (DHS; C. R. Snyder et al., 1991) consists of two subsets of items measuring Agency and Pathways. The authors used bifactor analysis to evaluate the dimensionality structure of the scale. Data from 676 persons (295 psychiatric patients, 112 delinquents, and 269 students) were analyzed. The authors conclude that although the Pathway items seem to explain some additional variance when the Hope scale variance is partionalized out, the DHS allows unidimensional measurement.     

Single-letter recognition accuracy and position information: Benefits with a symbolic cue

Summary This study reports two experiments designed to test a model that has as a basic assumption that position information is at the basis of the cueing benefits observed in single-item recognition tasks with accuracy as the dependent variable. In the experiments, two cueing conditions were used; a 100%-valid symbolic-cue condition and a neutral-cue condition. In Experiment 1, in which position information was sometimes missing, the symbolic cue brought a significant benefit. In Experiment 2, in which position information was always available, no benefit was obtained. These results are consistent with, and support, the model. Improved knowledge of position is at the basis of the cueing benefits observed in this type of task.     

No vigilance deficit found in either young schizophrenic or ADHD subjects

Vigilance deficits have been found in both schizophrenic and ADHD subjects. The two patient groups have never been directly compared on any vigilance measure, however. In the present study 20 early-onset schizophrenics were compared to 20 ADHD adolescents on a Degraded Stimulus Continuous Performance Test (DS-CPT). A comparison group of 30 normal adolescents was also included. Results showed no significant differences between the three groups on any of the DS-CPT measures. Different hypotheses are put forth to explain the findings, among them that the task may be insensitive to identifying sustained attention deficits in adolescent populations.     

Teaching self-protection to young children

Self-protective behaviors were taught to three preschool children in order to prevent the opportunity for abduction. An analogue measure of self-protection was developed in which confederate adults approached and verbally attempted to lure each child from the setting, before, during, and after training. A multiple baseline design across subjects was used. During baseline, all the children displayed susceptibility to the lures. Training procedures included modeling, behavior rehearsal, and social reinforcement. Within 1 week after training began, all children displayed appropriate responses to all of the lures both in the training setting and in the community.     

Groups of individuals who are moderately mentally retarded sharing their activities with passive low-functioning companions

This study involves a program in which two groups of individuals with moderate mental retardation served as peer caregivers with two passive companions (trainees). The main question was whether each group would learn to plan and share daily activities with one trainee, increasing the trainee's activity level. Other questions were: (1) whether peer caregivers would enjoy working with the trainees; (2) whether the job of peer caregiver would occasion social/adaptive behaviors not usually observed in the peer caregivers' repertoire; and (3) whether staff would perceive program effects on peer caregivers' and trainees' behavior. Results showed that the groups of peer caregivers learned to perform independently and accurately, increasing and maintaining the activity of the trainees. Peer caregivers seemed to like (or at least not to mind) working with the trainees, and their job brought about social/adaptive behaviors not commonly seen in their repertoire. Staff ratings confirmed that the program had positive effects on trainees and peer caregivers. General implications of the findings are discussed.     

Brief report: Teaching persons with moderate mental retardation to use printed instructions and time cues in a work context

Printed instructions and programable watches were used for helping two adults with moderate mental retardation perform variable tasks and follow a time schedule for task execution. The subjects, who could not read, were to match the words appearing in instruction notes to identical words superimposed on illustrative pictures (and collected in a vocabulary form). The pictures identified through this matching explained the meaning of the words being matched (i.e., indicated to the subjects which responses/tasks to perform). Self-recording was also used. The results showed that both subjects learned to use the printed instructions and the watches successfully. The subjects' performance remained positive over time. Procedural aspects and practical implications of the study are discussed.
