Career change and congruence of personality type: An examination of DOT-derived work environment designations

Holland's theory of congruence of work environments was examined by analyzing the career redirection of 62 men of managerial and professional level who changed occupations between the ages of 33 and 54. Three-letter personality codes for each subject were obtained by administering the Strong-Campbell Interest Inventory. Dictionary of Occupational Titles codes for first and second occupation were obtained and then translated into Holland codes. These were compared to the personality code for each man to determine whether the first or second job was more congruent. It was found that 26 men changed to careers more congruent with their personality, 25 to careers less congruent, and 11 made no change. The results of the study do not lend support to Holland's theory, probably because of the imprecision of DOT categories for research purposes. The need for a more reliable means for coding work environments is discussed.     

Electromyographic indications of laryngeal-area activity during stuttering expectancy

Using surface electrodes, mean microvolt values of laryngeal-area muscle activity were determined for 13 male and 6 female stutterers during 10-sec periods in which single words were silently read and stuttering expectancy was indicated. No significant differences in levels of laryngeal-area muscle activity were found between periods of fluency expectancy and stuttering expectancy preceding both fluent and stuttered speech. The results were interpreted as being nonsupportive of the hypothesis that a breakdown in stutterers' laryngeal-area muscle activity occurs during moments of stuttering expectancy. In addition, the results suggest that the most common rationale for the utilization of laryngeal biofeedback procedures to enhance fluency should be questioned.     

Communicative stress and stuttering frequency during normal,whispered, and articulation-without-phonation speech modes

The effect of communicative stress on the frequency of stuttered syllables in 12 adult stutterers reading six different but equivalent passages using normal voicing, whispering, and articulation-without-phonation speech under a stress and a non-stress condition was studied. Although the frequency of stuttering was significantly greater in the normal voicing mode than in the whispering mode and greater in the whispering mode than in the articulation-without-phonation mode, no differences were found between the stress and the nonstress conditions with respect to stuttering.     

The ecological approach to perceiving as a foundation for understanding the development of knowing in infancy

The ecological thesis of direct realism is used as a framework for examining the development of knowing in human infancy. When information for perceiving is defined ecologically (i.e., relative to the situational context and to the physical dimensions, capabilities, and needs of the perceiver), knowing need not be construed as the act of using representations to give meaning to acts or percepts. Knowing, alternatively, is the act of noticing affordances, situation and perceiverspecific meanings of objects, according to their value to the perceiver for achieving specific goals. Changes with development in infant sensorimotor functioning may, in this view, be explained by a process of increasing economy in noticing potentially available affordances, rather than a process of constructing a representational system for making present something not present. Studies of three infant skills widely attributed to the onset of representation are examined with regard to this ecological thesis. Results indicate that the noticing of affordances is critically involved in each of these skills.     

Factors facilitating adjustment to unemployment: Implications for intervention

Conducted a community survey in the Fall of 1984 in a sample of high unemployment blue-collar census tracts in southeastern Michigan. Results of earlier analyses using these data showed that involuntarily unemployed workers had significantly elevated levels of depression, anxiety, somatization, and self-reported physical illness relative to a stably employed comparison group (Kessler, House, & Turner, 1987). Results presented in this paper document that this relationship is modified by social support (as measured by social integration and the availability of a confidant), self-concept, and various coping processes. Further analyses allowed us to determine the way in which these modifiers operate. The modifying effects of social support and coping operate primarily by buffering the impact of unemployment-related financial strain on the health outcomes. Self-concept operates primarily by attenuating vulnerability to other stressful life events. The implications of these results for the design and implementation of preventive interventions are discussed.     

Role of contextual imagery in associative recall

The advantage of interactive over separation imagery in associative recall was markedly diminished when a unique imaginary context was provided for each imaged pair of words. Separation imagery was much more sensitive to contextual redundancy than was interactive imagery. Context was viewed as facilitating organization at encoding as well as affecting cue loading at retrieval. A three-element associative model is described.
