Anatomic and environmental dimensions of stimulus-response compatibility: implication for theories of memory coding.

Reaction time was higher when the relation between stimulus location and anatomic hand was reversed (e.g., left light-right hand) rather than direct (e.g., left light-left hand), even though the environmental location of the hand (up or down) was unrelated to the location of the stimulus (left or right). This effect was shown to be due primarily to decision processes, rather than to interhemisphere transfer delay. This result does not support the view that long-term memory for responses encodes environmental but not anatomic dimensions.     

The development of the category-recall relationship in the sorting-recall task

The relationship between categorical organization and recall for children in grades two, four, and six (ages 8, 10 and 12 years, respectively), and for adults was investigated using the sorting-recall procedure. Subjects sorted unrelated words on individual cards into either two, four, or six categories prior to output, and recall performance improved significantly as a function of increased numbers of sorting categories. The category-recall relationship was shown to be independent of the effects of subject-determined item exposure time in sorting. This result was taken as evidence for a basic structural property of memory (“chunking”) that does not vary as a function of age. We further speculated that the slopes of the category-recall function obtained in this study suggest a limit on the size of organizational units in young children's memory.     

Functional significance of stimulus orientation: effects on orientation discrimination.

Children (6- and 9-year-olds) and adults were required to discriminate identical pairs of visual stimuli from mirror images. It was hypothesized that a key factor in performance would be the extent to which orientation was a functionally significant attribute of the stimuli. Two variables were manipulated, type of orientation discrimination and stimulus class. The first variable refers to the fact that the mirror images could be produced by either left/right or top/bottom reversals. Three classes of stimuli, varying in the extent to which a particular orientation was emphasized, were used: mobile objects (for which left/right orientation is assumed to be important); stationary objects (which lack comparable relevance for left/right orientation); and novel, abstract forms. The prediction was that if the discrimination task involved left/right reversals, as contrasted with top/bottom reversals, subjects would show an advantage for mobile objects, producing an interaction between stimulus class and orientation discrimination. In the first study, the subjects were children and performance was measured in terms of error rates. In the second study adults were tested, and reaction times were measured. Both studies manifested the predicted interaction. Results are discussed in terms of an information-processing framework, in which the incorporation of orientation-related features in the code representing a stimulus varies with the functional significance of the orientation to the stimulus class.     

A cross-linguistic study of the processing of causative sentences

The comprehension of sentences expressing instigative causation (e.g., The horse makes the camel run) was investigated in children between the ages of 2;0 and 4;4, speaking English, Italian, Serbo-Croatian and Turkish. Cross-linguistic differences in development reveal the roles of morphological (causative particle, case inflection) and syntactic devices (periphrasis, word order) in guiding children's processing of such constructions. It is suggested that local cues (inflectional suffixes, particles, specialized causative verb forms) contribute to the more rapid development of sentence processing strategies in Serbo-Croatian and Turkish. The word order systems of English and Italian, which require that the listener hold the entire sentence pattern in mind in order to determine underlying semantic relations, contribute to slower development on this task.     

A component model for diagnosing and treating children who stutter

Nine components of stuttering and their distribution among 54 children who stutter are described. The components are arranged into a model that includes four neurologic components (attending disorder, auditory-processing disorder, sentence-formulation disorder, and oral-motor disorder) and five traditional components (high self-expectations, manipulative stuttering, disruptive communication environment, unrealistic parental expectations, and abnormal parental need for the child to stutter). Diagnostic and treatment usefulness of the model are discussed. Thirty-two of the children have been followed through component-based treatment and 12 mo post termination. Results indicate that treatment was successful with 27 (84%) of the 32 children. Only one child regressed during the 12 mo after treatment ended. These results suggest that treating the neurologic and traditional factors which disrupt fluency improves maintenance and carry-over.     

Career satisfaction and role harmony in a sample of young women physicians

In a sample of young women physicians, self-ratings of Career Satisfaction and Role Harmony were correlated with a group of situational, achievement, and personality variables. Career Satisfaction was extremely high with about 88% reporting they are satisfied or very satisfied. However, over half experienced at least a moderate amount of strain in integrating professional and sex roles. In addition women who were high on both Career Satisfaction and Role Harmony were compared with the others in the sample and individual differences were apparent: These women were exceptionally confident, intellectually resourceful, and tolerant; they tended to have clear priorities with either family or work coming first. Overall their current level of personality adjustment was superior to the others who, as a group, were very well-functioning women.     

Situational and personality determinants of a victim's identification with a tormentor

The effects of two situational (tormentor legitimacy and tormentor justification) and two personality (victim's belief in the just world and victim's Machiavellianism) factors on several reactions of a victim to his tormentor were explored. Greater conformity by victims to their tormentor's opinions occurred when the victims believed strongly in the just world and when the tormentor was well justified for his behavior; there was a greater conformity towards the tormentor in these conditions than towards a neutral nontormentor. The tormentor received less positive evaluations from the victim when he acquired his role illegitimately or when the victim was Machiavellian; when the tormentor acquired the role legitimately, he was liked no less than the nontormentor. The experimental variables did not affect behavioral imitation of the tormentor or the interpersonal distance maintained by the victim. The results failed to conform to any simple identification process. Several explanations for these results are explored and directions for additional research are discussed.
