Cooperative education,career exploration,and occupational concepts for community college students

Super's self-concept theory of career development and Jordaan's construct of vocational exploratory behavior were used to investigate the outcomes of a college cooperative education program. The effects of an internship were compared with those of a classroom experience with regard to change in similarity between self- and occupational pictures (incorporation scores). A measure of incorporation was administered to 85 students who worked during one quarter, and 99 students who were enrolled in classes during the same period. Both groups increased in incorporation for prospective occupation (t = .01, p > .10). For the internship group no difference was found between increase in incorporation for first- and second-choice occupation (t = .24, p > .10), while for the classroom group the increase in incorporation for prospective occupation was significantly greater than for second-choice (t = 2.80, p < .01). This result was discussed in light of the implication that the internship stimulated vocational exploratory behavior. Roe's system of occupational classification revealed an unexpected lack of relationship between first- and second-choice occupations. These findings were discussed in relation to the career development of the working-class community college sample.     

Limb apraxia and motor performance

This study was desinged to determine if motor deficits in limb apraxia are task specific. Non-brain-damaged patients and apraxic and nonapraxic patients with left hemisphere damage performed language and limb apraxia tests and six motor tasks with the left hand. Contrary to previous data, no significant group differences occurred on a finger tapping task. Although task complexity or sequencing requirements affected group differences, greatest apraxic impairment was noted on a task of precise steadiness, but only when its response inhibition requirements were increased. This pattern of deficits appears to be associated with greater involvement of the premotor area in the apraxic group.     

Influence of stuttering therapy on clinicians'' disfluencies: Effects of client modeling

This study investigated whether student clinicians working with stutterers subsequently produce more disfluencies than student clinicians providing therapy to clients with other speech and language disorders. Seventeen graduate students working in a 6-wk summer camp setting were divided into two groups: eight who provided treatment for stutterers (group 1) and nine who provided therapy for clients with other communication disorders (group 2). All student clinicians were recorded during spontaneous speaking and oral reading tasks prior to camper arrival and following camper departure. An eight-category classification system was used to determine disfluency types. Findings revealed that Group 1 clinicians significantly decreased their total disfluencies between pre- and post-camp recordings on the spontaneous speaking task. Unexpectedly, this same group also substantially increased part-word repetitions and sound prolongations. The possibilities of incidental learning, reverse modeling, and overidentification with stuttering clients are discussed.     

The effect of grammatical complexity upon disfluency behavior of nonstuttering preschool children

The effect of grammatical complexity on the disfluency behavior of nonstuttering 3- and 4-yr-old children was examined. Thirty normal children repeated after the examiner 30 sentences which represented six different grammatical constructions. These grammatical constructions represented a range of grammatical complexity.The total number of disfluencies that occurred in each sentence type was compared. The occurrence of specific disfluency categories in each sentence type was also examined. Subjects produced significantly more disfluencies on passive sentences than on any other sentence type. The passive elicited significantly more interjections, word repetitions, and revisions than the other sentence types.The effect of sentence type on imitation performance was also examined. The auxiliary Have and negative sentence types elicited significantly more imitation errors than other sentence types. Initiation and fluency performance for individual subjects were also examined.The results of the present investigation suggest that when grammatical complexity is controlled, the relationship between disfluencies and grammatical complexity is complicated. When grammatical constructions were relatively difficult for children, complexity affected the occurrence of disfluencies. However, factors other than grammatical complexity affect the occurrence of disfluencies in pre-school children.     

Effects of imaginal exposure to feared disasters in obsessive-compulsive checkers

The combined effects of imaginal exposure to feared catastrophes and in vivo exposure to external stimuli were compared with the effects of in vivo exposure alone in 15 obsessive-compulsives with checking rituals. The first group received 90 min of uninterrupted exposure in imagination, which concentrated mainly on disastrous consequences, followed by 30 min of exposure in vivo to stimuli-situations which triggered rituals. The second group was given 2 hr of exposure in vivo only. Both groups were prevented from performing rituals. Treatment consisted of 10 daily sessions within a 2 week period.Assessments were conducted before and after treatment and at follow-up ranging from 3 months to 2.5 yr with a mean of 11 months. At post-treatment both groups improved considerably and did not differ. But at follow-up those who received imaginal and in vivo exposure maintained their gains, whereas the group who were treated by exposure in vivo alone evidenced partial relapse on four of the six dependent measures. The results tend to indicate that a closer match between a patient's internal fear model and the content of exposure enhances long term treatment efficacy.     

Heart rate conditioning in young infants using a visual conditional stimulus

Trace heart rate conditioning was evaluated in 16 infants having a mean age of 4.5 months. The Experimental Group received a 3-sec blinking light pattern as the CS, followed by a 3-sec interstimulus interval (ISI), and 3-sec tone as the UCS. The Control Group received an equal number of presentations of the CS and UCS at randomized intervals and in a randomized order. The acquisition of a conditioned deceleration during the period which included the visual CS and the ISI was demonstrated only in the Experimental males. Response differences were also found in the absence of the auditory UCS, with only Experimental females exhibiting a deceleration.     

Developmental changes in infants' sensitivity to octave-band noises

Localization responses to octave-band noises with center frequencies at 200, 400, 1000, 2000, 4000, and 10,000 Hz were obtained from infants 6, 12, and 18 months of age. During an experimental trial, an octave-band noise was presented on one of two speakers located 45° to each side of the infant. A head turn to the noise (correct response) was rewarded by activating an animated toy on top of the speaker. The intensity of the noise was varied over trials (method of constant stimuli) to determine thresholds at each center frequency. Thresholds for the lower frequencies were approximately 5–8 db higher in the 6-month-old infants compared to the older infants. However, there were no consistent differences among groups at the higher frequencies. Infant thresholds were found to be 20–30 db higher than adult thresholds at the lower frequencies. At the higher frequencies thresholds for infants were approaching those of adults.     

Conditioned suppression of drinking: A measure of the CR elicited by a lithium-conditioned flavor

The CR elicited by an exposure to a lithium-conditioned flavor CS+ was measured in a paradigm which closely approximated traditional conditioned suppression of licking. Rats were first trained to discriminate between a lithiumpaired flavored solution (CS+) and an equally familiar, but safe, flavored solution (CSc). Then, while they consumed a differently flavored test solution, the rats were intraorally infused with either the CS+ or the CSc flavored solution. The immediate aftereffect of the CS+ exposure on consumption of the Test Solution (TS) measured the CR. The CS+ exposure suppressed the consumption of both a novel flavored TS and an unflavored water TS. The strength of the suppressive CR was influenced by the nature of the TS and by the dose of lhe lithium US.     

Applications of self-efficacy theory to the understanding and treatment of career indecision

The present study was designed to investigate the utility of Bandura's self-efficacy theory to the understanding and treatment of career indecision. More specifically, the study involved the development of a measure of self-efficacy expectations with regard to 50 tasks or behaviors required in career decision making and the examination of the relationships of career decision-making self-efficacy to several components of vocational indecision. A total of 346 subjects, 154 students attending a private liberal arts college and 193 students attending a large state university, were administered the measure of career decision-making self-efficacy expectations and the Career Decision Scale (Osipow, Carney, Winer, Yanico, & Koschier, Columbus, Ohio: Marathon Consulting and Press, 1980). In addition, Scholastic Aptitude Test verbal and math scores were obtained for the liberal arts students, and American College Test math and English subtest scores were obtained for the state university students. Results indicated first that college students in general express considerable confidence in their ability to complete the tasks necessary to make career decisions. In addition, however, the strength of students' career decision-making self-efficacy expectations was strongly and negatively related to overall levels of career indecision and was, in particular, related to the component of indecision described as a lack of structure and confidence with respect to career decisions. Relationships of career decision-making self-efficacy expectations to ability level were negligible. Based on the findings of this study it is suggested that the concept of career-related self-efficacy expectations provides a useful framework for the understanding, assessment, and treatment of at least some of the antecedents to vocational indecision.
