Oral overcorrection: side effects and extended applications.

Experiment 1: In a specialized daycare program the use of oral overcorrection (contingent toothbrushing with an oral antiseptic) to suppress one child's thumbsucking at Language Time was found to suppress the behavior of another child who was not treated but who witnessed the target child's treatment. Experiment 2: The main effects of oral overcorrection were replicated. Contingent overcorrection threats (warnings), used independently, were then shown to suppress thumbsucking behavior that had returned to its baseline level. These effects were maintained one month after the threats were discontinued, but they did not generalize to other activity periods, particularly Nap Time. Experiment 3: Contingent threats were found to suppress the persistent nap-time thumbsucking of the child from Expt 2. Increments in certain other (nonoral) inappropriate behaviors were correlated with the suppression of thumbsucking. Threats to use oral overcorrection contingent upon nonoral misbehaviors at Nap Time were not effective. However, the actual use of oral overcorrection for these categories of nonoral misbehavior served to suppress these behaviors. Experimental controls combined treatment reversal and multiple baseline single-subject designs.     

Effect of role choice on vocational high school students

This study was an attempt to determine whether the role choice dimension of Holland's theory was applicable to vocational high school students. The results of the study indicate that students with a clear role choice have significantly higher mean achievement scores, are more satisfied with their training program and have a lower attrition rate than students with an unclear role choice. These results seem to suggest that school counselors should listen to what students say they want to do in their work role.     

Bilateral tachistoscopic word perception of stutterers and normal subjects

Bilateral tachistoscopic procedures were utilized to investigate the visual half-field preferences of 15 stutterers and a group of 15 normal controls. Statistical analyses indicated a right visual half-field preference for the control group. In contrast, a significant visual half-field preference was not revealed for the stuttering group. However, further analysis revealed that a significantly larger proportion of stutterers, compared to controls, demonstrated a left visual half-field preference. Results indicated reversed cerebral processing for the stuttering group as compared with the control group.     

Cumulative integrated electromyographic activity of selected speech-related muscle groups of nonstutterers during massed oral readings

The electromyographic (EMG) integrated amplitude of masseter and laryngeal muscle groups were analyzed during five massed oral readings of 16 nonstuttering adult subjects. Reduction in dysfluencies were observed over the five trials as was a reduction in reading time across trials. Significant decreases in EMG activity across trials were found for the laryngeal, but not the masseter, EMG activity. This suggests that changes in vocal behavior thought to accompany adaptation are reflected in decreases in EMG activity of select speech-related muscle groups.     

Implementing self-concept in vocational choice in the Arab Middle East

Considerations for adopting self-concept theory in vocational choice for the Arab Middle East were explored examining three limitations. The extent to which these limitations (freedom to choose occupations, availability of options, and psychological readiness) operate in the Middle East was identified. It was concluded that the self-concept theory of vocational choice is not yet viable for this area of the world. However, as the process of modernity takes place, the area can be an excellent proving ground for predictions.     

Vocational interest and personality differences between development and research personnel: A field study

Employees classified into development and research groups were contrasted for differences in vocational interest and personality inventory responses. Discriminant and classification analyses indicated that these two groups could be distinguished. Development personnel exhibited greater interests in supervisory-related areas, but researchers showed a tendency toward high specialization and academic interests. With respect to personality characteristics, development personnel described themselves as more dominant, defensive, and achieving, yet less critical than research personnel.
