Acknowledgment of handicap as a tactic in social interaction

Nonhandicapped people often report discomfort and uncertainty when interacting with handicapped individuals. The three studies reported here investigated a possible tactic that handicapped people could use to reduce a fellow interactant's discomfort and uncertainty. Nonhandicapped subjects watched two videotapes of handicapped individuals being interviewed. Each subject then chose the handicapped person with whom he would prefer to work on a cooperative task. Results of all three studies supported the hypothesis that a handicapped person acknowledging his handicap will be preferred to a handicapped person who does not acknowledge his handicap. In Study 1, subjects significantly preferred a handicapped person who acknowledged his handicap to a handicapped person who did not disclose anything personal. In Study 2, subjects significantly preferred an acknowledging person over one who made a personal disclosure other than about his handicap. In Study 3, subjects preferred the individual acknowledging a handicap over one who disclosed something else personal even when the acknowledging individual was clearly nervous about doing so. These results suggest that acknowledging the handicap may be a promising tactic.     

Comparison and combination of recall and Background Interference Procedures for the Bender-Gestalt Test with brain-damaged and schizophrenic patients.

The Bender-Gestalt Test was administered under standard, recall, Background Interference Procedure (BIP), and BIP-recall conditions to 20 brain-damaged and 20 schizophrenic male inpatients. Individual recall, BIP, and BIP-recall scores differentiated between the groups prior to controlling for IQ, but only recall and BIP-recall continued to discriminate once IQ was held constant. The use of difference scores corrected for standard copy performance (base level) resulted in improved diagnostic discrimination compared to difference scores alone. However, this procedure also produced a substantial multiple correlation with IQ and a consequent loss of group differentiation for the BIP difference score, while failing to yield an appreciable increase in predictive accuracy over individual scores for recall and BIP-recall. Nonetheless, a significant effect emerged independently of both recall and IQ for the BIP-recall score, suggesting that the BIP hypothesis may have merit within the context of memory functioning.     

A validation study of the Draw-A-Person as a measure of racial identity acceptance

The present study is a replication of Schofield's findings (1978) in the use of the Draw-A-Person as a measure of racial identity acceptance. Unlike Schofield's study, the present investigation involved an adolescent sample of blacks and whites, and race of figure drawn was determined by judges' consensus rather than an objective scoring system. The findings generally supported those of Schofield and the racial identity and preference literature as a whole in revealing blacks to be less accepting of their racial identity than whites.     

Serial learning in the pigeon.

Three pigeons learned to peck four colors in a particular sequence, regardless of how these colors were positioned on four response keys and without feedback following each response. This demonstrates that serial learning is possible in subprimate animals.     

Temporal control of behavior and the power law

The performance of rats and pigeons under fixed-interval schedules was studied in two experiments. The duration of postreinforcement pause was a declining proportion of fixed-interval duration. For pigeons this was true both when the duration of the reinforcer was fixed and when it was increased in direct proportion to increases in fixed-interval duration; the longer reinforcer durations did, however, lengthen the postreinforcement pause at higher schedule values. A quantitative analysis of data from Experiments 1 and 2 and from other studies showed that fractional exponent power functions described the relationship between postreinforcement pause and fixed-interval value; similar functions have previously been observed in studies of temporal differentiation. It was concluded that power functions reflect a direct causal, rather than artifactual, relationship between performance and the temporal requirements of reinforcement schedules.     

Oculomotor programming disturbances in the dementia syndrome

Three types of oculomotor programming disturbances are described in patients with the dementia syndrome. This report describes two of these abnormalities, poorly regulated gaze patterns and a programming type of gaze perseveration. All patients showed poorly regulated gaze patterns in contrast to the normal controls, whereas on the whole only the moderately affected patients showed the programming type of gaze perseveration. The third type of oculomotor programming disturbance is efferent perseveration of gaze (a hypokinetic, "staring" type of gaze pattern) and can be seen with severe dementia. The possible significance of these findings is discussed.     

Concurrent validity of a children's version of the Stroop Color-Word Test: the Fruit Distraction Test

To assess the concurrent validity of the Fruit Distraction Test, the Stroop Color-Word Test and the Fruit Distraction Test were administered to two groups of boys aged 12 yr. (N = 63) and 8 yr. (N = 52). Partial correlations, with IQ controlled, based on time and error scores derived from both tests, provided no convincing evidence that the Fruit Distraction Test is a valid downward extension of the Stroop.     

Electromyographic tension levels in stutterers and normal speakers

Electromyographic (EMG) recordings of masseter muscle tension during conversational speech by six adult stutterers were compared to EMG levels of 6 normal speakers. Stutterers' and normal speakers' tension levels were significantly different; however, there was no correlation found between level of tension and severity of stuttering.
