A self-efficacy approach to the career development of women

An approach to the conceptualization and facilitation of women's career development based on Bandura, 1977, Bandura, 1977, 84, 191–215) self-efficacy theory is presented. The model presented postulates that largely as a result of socialization experiences, women lack strong expectations of personal efficacy in relationship to many career-related behaviors and, thus, fail to fully realize their capabilities and talents in career pursuits. Sex differences in the access to and availability of four sources of information important to the development of strong expectations of personal efficacy are reviewed and discussed in relationship to women's career decisions and achievements. The utility of the proposed model for integrating existing knowledge of women's career development, for generating productive avenues of inquiry, and for guiding intervention efforts is discussed. The conceptual framework provided is seen as having implications for the career development of men as well as women, but the focus herein is on its potential for contributing to knowledge of the career development of women.     

Case report of stuttering acquired in association with phenytoin use for post-head-injury seizures

Previous research indicates that stuttering and deficits in motor performance may be associated with the use of phenytoin (Dilantin). The present report concerns a case of stuttering acquired in association with phenytoin use for post-head-injury seizures. The extent and nature of dysfluencies and the motor performance of speech and nonspeech muscle systems were evaluated over an extended period during which changes in anticonvulsant medication were made. Reductions in dysfluency levels and improved motor performance were observed following a medication change from phenytoin to carbamazepine. Performance on tests assessing nonmotor functions, such as memory and attention, was equivalent before and after the medication change. The apparent association between dysfluency levels, motor performance deficits, and phenytoin suggest that in the present case stuttering resulted in part from a general impairment in motor control.     

A test of the distraction explanation of disfluency modification in stuttering

The distraction explanation of changes in stuttering rate was examined in the present experiment. Twelve stutterers were compared with 12 nonstutterers who were matched for age, sex, and level of education. Subjects were tested for disfluency production under conditions designed to reflect the dimension of distraction. These conditions were: (a) over attention to speech (counting speaking errors). (b) “normal” conditions (no additional task), and (c) distraction (pursuit tracking of an irregular target). The results showed no effect on stuttering rate that could be attributed to the distraction conditions. However, stutterers rated the difficulty of these conditions in concordance with the distraction theory. It was suggested that, while stutterers' perceptions may account for the popularity of the distraction explanation, evidence supporting the theory is lacking.     

The effects of alternatives on the salience of reward allocation norms

In a dyadic bargaining situation there is considerable evidence that the alternative outcomes of the bargainers (if they cannot reach agreement) have important effects on bargaining outcomes. Under the assumption that situational factors affect the nature of the relation between the alternatives of the bargainers and bargaining outcomes, the effects of two factors were assessed: the relative size of the reward to be negotiated (excess of prize minus alternatives) and the magnitude of the difference in the alternatives of the two bargainers. Using college students as subjects, the predictions of two models were also contrasted: the equal excess model and Shapley-w. The relative size of the prize did not have a significant effect on the accuracy of the two models, but the magnitude of the difference in alternatives had marked effects. The results also suggest that the Shapley-w model may be more accurate when the bargainers are relatively inexperienced and cooperatively oriented, whereas the equal excess model may be more accurate when the bargainers are relatively sophisticated and competitively oriented.     

Reversible operations in the balance scale task

The development of two types of reversible operations was examined in three tasks involving a two-armed balance scale. The first type of reversible operation, compensation between dimensions, was shown to undergo considerable development between eighth grade and college. Even eighth graders were inconsistent in applying compensation to those versions of the balance scale task that required it. Some subjects, primarily preschoolers, used the given information in a way that was the opposite of that required for correct answers, a result that has been reported for other tasks requiring compensation. A second type of reversible operation, termed “correspondence of patterns”, was also tested and it was tentatively concluded that the responses of the modal college student are not fully reversible in this sense. This finding is also similar to results obtained in judgments of time, speed, and distance and in social judgment studies with college students.     

Development of phonetic memory in disabled and normal readers

The development of phonetic codes in memory of 141 pairs of normal and disabled readers from 7.8 to 16.8 years of age was tested with a task adapted from L. S. Mark, D. Shankweiler, I. Y. Liberman, and C. A. Fowler (Memory & Cognition, 1977, 5, 623–629) that measured false-positive errors in recognition memory for foil words which rhymed with words in the memory list versus foil words that did not rhyme. Our younger subjects replicated Mark et al., showing a larger difference between rhyming and nonrhyming false-positive errors for the normal readers. The older disabled readers' phonetic effect was comparable to that of the younger normal readers, suggesting a developmental lag in their use of phonetic coding in memory. Surprisingly, the normal readers' phonetic effect declined with age in the recognition task, but they maintained a significant advantage across age in the auditory WISC-R digit span recall test, and a test of phonological nonword decoding. The normals' decline with age in rhyming confusion may be due to an increase in the precision of their phonetic codes.     

Memory without organization: Properties of a model with random storage and undirected retrieval

A very simple spatial model of memory storage and retrieval is described, analyzed, and discussed. The postulated memory is without organization in the sense that neither the place of storage nor the order of search during retrieval is influenced by the nature of the information being stored or retrieved. The memory consists of a three-dimensional space containing a large number of homogeneously distributed loci at which data may be stored. Data received near each other in time are stored at nearby locations. Access is by an undirected expanding-sphere search. The model exhibits a wide variety of quantitatively and qualitatively humanlike behavior with respect to both standard learning and forgetting paradigms and with respect to frequency effects and other phenomena in word processing.     

Required relaxation: a method of inhibiting agitative-disruptive behavior of retardates

Institutionalized retardates frequently exhibit agitative-disruptive behavior. Recent experiments have shown that overcorrective training in specific types of behavior can inhibit inappropriate behavior. A procedure was developed in which overcorrective practice in relaxation was given to each of eight adult retardates for their disruptions. The agitated resident was required to spend a fixed period of time in relaxation in his own bed upon each occurrence of agitation. This overcorrective relaxation resulted in a rapid, enduring and almost complete reduction in such behavior as self-injury, threats, physical aggression, screaming, crying, cursing and tantrums. Ward attendants strongly preferred the required relaxation procedure to the time-out technique and other inhibition procedures they had used. The procedure appears to be about as effective as alternative techniques and to have the advantages of ease of implementation and acceptability by ward staff and retardates as a ‘reasonable’ reaction to agitation.     

Cognitive structures in comprehension and memory of narrative discourse

The effects of structure and content variables on memory and comprehension of prose passages were studied in two experiments. The experimental passages exemplify a class of simple narrative stories that is described by a generative grammar of plot structures. A comprehension model is proposed that assumes a hierarchical organizational framework of stories in memory, determined by the grammar, representing the abstract structural components of the plot. The quality and characteristics of subjects' memory for stories were tested on a variety of experimental tasks in which story organization was manipulated. Comprehensibility and recall were found to be a function of the amount of inherent plot structure in the story, independent of passage content. Recall probability of individual facts from passages depended on the structural centrality of the facts: Subjects tended to recall facts corresponding to high-level organizational story elements rather than lower-level details. In addition, story summarizations from memory tended to emphasize general structural characteristics rather than specific content. For successively presented stories, both structure and content manipulations influenced recall. Furthermore, repeating story structure across two passages produced facilitation in recall of the second passage, while repeating story content produced proactive interference. The implications for a model of memory for narrative discourse are discussed.
