The use of a portable delayed auditory feedback unit in stuttering therapy

A portable on-the-body delayed auditory feedback was used in the establishment and transfer modes of fluent speech in a stutterer while he was on the Monterey Fluency Program. The performance of the client was compared with a “standard” population of stutterers. The portable DAF was comparable to the larger DAF in establishment and superior in transfer with minimal behavioral and technical problems. Use and potential value of the portable DAF in transfer and maintenance phases of therapy are discussed.     

The impact of family,peers, and educational personnel upon career decision making

This study examined the amount of support, encouragement, and discouragement women received from the important people in their lives when they considered enrolling in a male-traditional vocational course. Data were collected from 470 women enrolled in California vocational training programs. Approximately equal numbers of women in male-dominated (Nontraditionals) and female-dominated programs (Traditionals) completed the self-administered questionnaire. Among those in female-traditional programs, 117 had considered taking a nontraditional program, but never did (Considereds). Data were analyzed for each of these three groups. Results revealed the Nontraditionals consistently received more support and enocuragement than did the Traditionals. However, the only significant support differences between the Nontraditionals and Considereds were in terms of the males in their lives. The Considereds and Traditionals also expected more discouragement than the Nontraditionals indicated they had actually received. Recommendations are made to improve educational quality and to foster equality of educational opportunity.     

On the psychological reality of a natural rule of syllable structure

If natural rules in phonology, such as the rule which deletes a word final consonant before a consonant, are frequently found in unrelated languages, it must be because they tap universal features of production and/or perception. The present experiment employed a learning task to see whether naive subjects have a predisposition for the natural rule as opposed to its converse (consonant deletion before a vowel). The Ss first learned four novel words (nouns) - two beginning with a consonant, two with a vowel - as paired associates to English ‘translations’. Then three novel adjectives were combined with each of the four nouns, following the natural rule for one group of Ss, the unnatural rule for the other. The twelve phrases were cued by their English translations and the S had to respond to each with the phonologically correct sequence of adjective and noun; confirmation followed each response. The Ss learning the unnatural corpus had a strong tendency to give natural responses, whereas the converse was not true. Consequently they made many more errors en route to mastery than their natural counterparts, even when the operative rule was displayed on the first trial by presenting in turn each adjective with its four following nouns. It appears that our Ss had implicit knowledge of the natural rule, even though it does not operate to any significant extent in English.     

Family resemblances: Studies in the internal structure of categories

Six experiments explored the hypothesis that the members of categories which are considered most prototypical are those with most attributes in common with other members of the category and least attributes in common with other categories. In probabilistic terms, the hypothesis is that prototypicality is a function of the total cue validity of the attributes of items. In Experiments 1 and 3, subjects listed attributes for members of semantic categories which had been previously rated for degree of prototypicality. High positive correlations were obtained between those ratings and the extent of distribution of an item's attributes among the other items of the category. In Experiments 2 and 4, subjects listed superordinates of category members and listed attributes of members of contrasting categories. Negative correlations were obtained between prototypicality and superordinates other than the category in question and between prototypicality and an item's possession of attributes possessed by members of contrasting categories. Experiments 5 and 6 used artificial categories and showed that family resemblance within categories and lack of overlap of elements with contrasting categories were correlated with ease of learning, reaction time in identifying an item after learning, and rating of prototypicality of an item. It is argued that family resemblance offers an alternative to criterial features in defining categories.     

Immediate and delayed reinforcers for flavor preferences in rats

When rats received, on alternate days, one flavored saccharin solution for 5 min and a differently-flavored saccharin solution for 60 min, they showed no consistent preference between the flavors. On the other hand, when they received one flavor in a concentrated saccharin solution and a different flavor in a dilute one, they preferred the first flavor in tests with saccharin concentration held constant; also, rats learned to prefer a flavor immediately followed by a concentrated saccharin solution to one followed by nothing. They showed no consistent preference, however, between a flavor followed 30 min later by a concentrated saccharin solution and one followed by nothing; but they learned to prefer a flavor followed 30 min later by a dextrose solution to one followed by nothing. In other words, consummatory responding did not reinforce flavor preference, sweet taste did so with immediate but not delayed reinforcement, and nutrition did so even with delayed reinforcement.     

One-way characteristic performance of rats under two-way signaled avoidance conditions

In Experiment 1, the conflict in a two-way active avoidance was reduced by allowing rats to avoid one of two levels of shock by running onto a safe platform which covered one half of the grid floor. Performance characteristics of one-way avoidance were obtained regardless of the shock intensity. Groups with no platform showed poor performance. Experiment 2 suggested that the facilitatory effect of the platforms was not due to the cue associated with platform removal. These results suggest that (a) rats can quickly learn to enter a spatially aversive location, (b) fast avoidance learning may be obtained in a two-way setting, and (c) rats seem capable of selective association of environmental and aversive stimuli.     

Disinhibition of aggression through diffusion of responsibility and dehumanization of victims

The present study tested derivations from social learning theory on the disinhibition of aggression through processes that weaken self-deterring consequences to injurious conduct. Subjects were provided with opportunities to behave punitively under diffused or personalized responsibility toward groups that were characterized in either humanized, neutral, or dehumanized terms. Both dehumanization and lessened personal responsibility enhanced aggressiveness, with dehumanization serving as the more potent disinhibitor. Escalation of aggression under conditions of dehumanization was especially marked when punitiveness was dysfunctional in effecting desired changes. The uniformly low level of aggression directed toward humanized groups, regardless of variations in responsibility and instrumentality of the conduct, attested to the power of humanization to counteract punitiveness. Results of supplementary measures are consistent with the postulated relationship between self-disinhibiting processes and punitiveness. Dehumanization fostered self-absolving justifications that were in turn associated with increased punitiveness. Findings on the internal concomitants of behavior performed under different levels of responsibility suggest that reducing personal responsibility heightens aggressiveness more through social than personal sources of disinhibition.     

Life history correlates of ministerial success

Life history or biodata correlates of ministerial success were investigated for a group of 92 Seventh-Day Adventist ministers. The criterion data reflected their current level of success and the predictors reflected their status as seminarians between the years 1940 to 1950. Two significant bivariate correlations indicated that successful ministers chose their career later than less successful ones and that earning college expenses was predictive of success. A stepwise multiple regression process was used to develop a weighted prediction model, but the model did not hold when cross-validated.     

Job satisfaction among students in work education programs

Data were collected from 1016 students in grades 9–14 from 50 work education programs. Data were also collected from 696 similar students who held part-time jobs but were not participating in work education programs. Participating students were significantly more satisfied with their jobs than were the nonparticipating students. Group atmosphere, availability of adult role models, meaningfulness of work roles, and availability of feedback accounted for much of the variation in job satisfaction among students.     

Eleven-year career stability and change as reflected in Project Talent data through the Flanagan,Holland, and Roe occupational classification systems

The vocational psychologist seeks classifications of occupations which maximize career stability as occupations change from time to time in the life. This study investigates the extent of career stability and the patterns of career change which have occurred in the lives of Project TALENT twelfth grade students in the 11 yr elapsing since they were tested. “Career” plans in the last year of high school and at 1, 5, and 11 yr after testing were classified by the Flanagan, Holland, and Roe occupational classification systems in order to study the career stability and patterning within each system and to contrast both among systems. Career stability proved to be about the same in all three classification systems but decreased in all cases as the interval over which it was measured increased. Career stability increased as subjects grew older, proving to be the greatest from 5 to 11 yr after high school. Patterns of change mildly conformed to the circular patterns claimed by Holland and Roe for their systems and the linear pattern hypothesized for the Flanagan system. Generally, the direction of “career” flow was away from intellectual careers to careers in business and sales but each system had unique results as well.
