Stuttering theory,research, and therapy: A five-year retrospective and look ahead

This article reviews events in stuttering theory, research, and therapy that have transpired during the past 5 years. After the retrospective review, current work in the area of stuttering is examined. This analysis of the past and present was conducted in an effort to give clearer direction to future efforts to understand the disorder, and to study and treat it more effectively.     

Click location in sentences: A test of the linguistic competence of seven-year-old fluent and disfluent males

Ten fluent and ten disfluent 7-yr-old males were presented simple and complex fully grammatical, anomalous and scrambled sentences. A click (35-msec 1-kHz tone burst) had been superimposed within three positions to the right or left of the major syntactic boundary in each sentence. The subjects heard the sentence, repeated the sentence, and marked on a preprinted version of the sentence where they heard the click. It was expected that children with greater language facility would more probably locate the click veridically. By the same reasoning, less complex syntactic structures should be expected to influence click placement less than more complex utterances. The following results were obtained: (a) the disfluent group gave a greater number of correct responses than the fluent group; (b) more correct responses were observed for simple sentences than for complex sentences for both groups; and (c) fewer correct responses were observed for both simple and complex grammatical sentences than for anomalous and scrambled sentence types.     

Determinants of reduction in intended effort as a strategy for coping with anticipated failure

The present study investigated the use of reduction in intended effort as a strategy for protecting self-esteem from the threat of anticipated failure. It was hypothesized that people reduce the amount of effort they intend to exert when they expect a low probability of success on a highly ego-relevant task. Female subjects anticipated taking an easy (high probability of success) or difficult (low probability of success) test that was either high or low in ego relevance. Subjects' levels of intended effort and other task-relevant cognitions were assessed. It was found that subjects in the low-probability condition intended to exert less effort on the highly ego-relevant test than did subjects in the high-probability condition; probability of success had no effect on intended effort level on the low ego-relevance test. Subjects also reported that it was a worse day for a test in the low-probability condition than in the high-probability condition. The relevance of these findings to the egotism explanation of learned helplessness effects and general theories of motivation was discussed.     

Individual differences in the ability to focus and divide attention

This research deals with individual differences in the ability to focus and divide attention. Eighty-five subjects performed visual search and auditory detection tasks in three conditions: single channel, focused attention, and divided attention. Reaction time (RT) was fastest in the single channel condition, intermediate in the focused attention condition, and longest in the divided attention condition, and these effects were much stronger in the auditory than the visual task. Correlations among RTs in the three conditions were very high within modality (>.88), and lower between modalities (.5 to .6). The correlational data was well fit by a model that included separate factors for the visual and auditory tasks. Measures from the three attentional conditions within each modality loaded equally on these factors. The data provided no evidence for distinct abilities to divide or focus attention.     

Beyond the high point code in testing Holland's theory

This study was designed to test and expand Holland's vocational development theory by utilizing more than a single high point code in classification of personality patterns of jobs. Significant positive results were obtained to support Holland's premise that people search out environments and, hence, vocations that are compatible with their personalities. A more “refined” and/or “subtle” difference was shown in the personality-job relationships when two high point codes were used.     

Vocational interest orientations: A comparison of rural university and junior college freshmen

The increase in junior colleges imposed new demands on counselors. Some areas to be investigated are the differences in counseling programs between junior colleges and universities; the differences in student bodies; and the importance of vocational guidance. This study addresses itself to elements of those areas.Male and female samples were drawn from two rural educational institutions: a four year university and a junior college. Differences in vocational interest orientations were explored through the nonoccupational scales of the Strong Vocational Interest Blank (SVIB). For males significant differences were found on the academic achievement, diversity of interest, managerial orientation, and occupational level scales. Females differed on the diversity of interest scales.     

Applying an occupational classification to the work histories of young men and women

Holland's occupational classification was used to analyze the work histories of a national representative sample of young men and women ages 14 through 24. Hypotheses tested were concerned with the psychological orderliness of occupational changes, the relationship between occupational experiences and aspirations, and the relationship between consistent occupational codes and the stability of work histories. The analyses supported the usefulness of the occupational classification for organizing the work histories of both young men and young women. For both sexes, the classification reflected regular patterns of job changes. The category of a person's earlier job was an efficient predictor of a person's subsequent jobs; likewise, the category of a person's current job forecasted the category of his vocational aspiration. The consistency of an occupational code was also related to job stability for whites but not for blacks.     

Stage factors relating alienation and self-role diffusion

A study, controlling for age, sex, and vocational commitment of 290 adolescents (ages 17–19 and 20–22), was conducted to determine the relationship between self- and social alienation attitudes and the identity-role crisis of the adolescent stage.Specific subscale differences due to age and sex for social alienation were found. Younger adolescents expressed greater self-alienation than older males, who were significantly more self-satisfied than both younger and older females and younger males. The hypothesis suggesting that self-alienation reflects conflict and dissatisfaction emerging from identity-role discrepancies during the adolescent stage of psychosocial development, and would decrease with vocational commitment was supported for males but not females.
