Activity level: A comparison between actometer scores and observer ratings

Activity level of 13 boys (aged 9–13) from a day hospital program was measured using actometers in classroom, gym, woodshop, and group therapy settings. Ratings of Ss' activity were obtained from mothers using the Werry scale, and from six clinical staff familiar with the Ss using the Davids scale. It was predicted that activity ratings would have situationally specific relationships with actometermeasured activity level according to the rater's opportunities for observation. Comparisons between measures indicated that all clinical staff ratings correlated significantly with actometer activity in the classroom (r=.49 to r=.73), while mothers' ratings correlated significantly with actometer activity in gym (r=.67), and woodshop (r=.77), and with overall activity (r=.65), a combined measure derived from actometer scores in the four conditions tested. Five of six clinical staff raters showed significant interrater reliability (r=.58 to r=.83). Results are discussed in terms of their implications for solution of current problems in assessment of activity level and hyperactivity.     

Aspects of body image perception in obese and normal-weight youngsters

Perceptual and projective aspects of body image in obese youngsters (not in psychological treatment) and normal-weight youngsters 8–9 years of age and 12–13 years of age were investigated. The results indicate that perceptual distortions in estimating various body dimensions of oneself are primarily a function of age rather than weight status. The accuracy of estimating the weight of peers and an adult showed an association with the sex of the subject. No group differences were found in terms of projective aspects of body image as measured by barrier and penetration responses. This study suggests that obese youngsters in the middle childhood and entering puberty periods in comparison to normal-weight youngsters of the same age do not manifest differences in perceptual factors of body image.     

A study of repetition in aphasic patients

The ability of the aphasic patient to repeat a message is a capacity of considerable diagnostic value. While it is well known that certain aphasic groups (e.g., transcortical aphasics) repeat better than other groups (e.g., conduction aphasics), possible qualitative differences among the groups have not been subjected to analysis. To secure information on repetition profiles in various aphasic subgroups, a test consisting of 11 types of items, presented under conditions of both immediate and delayed recall, was administered to eight groups of aphasic patients. The results documented a significant difference across aphasic groups, one related to site of lesion but not to severity of comprehension defect. Performance proved to be a joint product of the length and the meaningfulness of the stimulus items. The delayed condition aided Broca's aphasics and impeded anomic aphasics; in addition, nonsense syllables proved to be easier on immediate recall, while meaningful stimuli, particularly those which were number related, were relatively easier on delayed recall. Finally, sound errors were more likely to be made by Broca's and “mixed anterior” aphasics, while meaning errors were particularly prominent among conduction aphasics. These results are discussed in terms of the mechanisms which may mediate repetition in aphasic patients.     

The possible causes of the sex ratio in stuttering and its implications

The incidence of stuttering has always been reported to be higher in males than in females. Possible causes of the unequal sex ratio include various ascertainment biases, incomplete reporting, social role differences, X-linked inheritance, or a combination of environmental and genetic elements. Each of these factors has been examined against data collected in the large family study of stuttering, and all but one have been eliminated. Only the gene-environment interaction hypothesis can be supported by the data. Statistical analysis confirms that the sex effect in stuttering is real and supports a threshold model for the sex difference. We conclude that the possibility of differences between males and females must be considered in any etiological research in stuttering.     

Question form analysis in discourse agreement between a mother and a language-learning child

This study analyzed the question form used in discourse between a mother and her language-learning child. Spontaneous taped data of mother-child interactions were collected at three different time periods. Initially the child was 2;3 and data collection stopped at 2;5. Analysis of dialogue units based on protocols of discourse proposed by Mishler (1974) was conducted. Results indicated that question chaining occurred most frequently in discourse, followed by arching, then embedding. All question forms except one were initiated by the mother. Evidence also indicated that the subject did not have the linguistic competence of allwh-question forms by 2;5. This study indicated that question chaining was the most frequent type of discourse analysis with this dyad.     

Interactions among levels of processing

This article examines associations among representations of physical, name, and category information by determining effects of category repetition on and following physical, name, and category match trials. Subjects decided whether two letters were from the same half of the alphabet. Category repetition effects were evidenced by faster ~nd more accurate responses when letters from the same half of the alphabet were used on successive trials. Although physical matches showed no effect of category repetition, name and category matches did. Trials following physical matches were less affected by category repetition than were trials following name or category matches. The results suggested that these category repetition effects were mediated by interletter associations: Reaction time increased with the alphabetic distance between preceding and current letters. However, these distance effects held only for forward (A → B) and not backward (B → A) alphabetic sequences, suggesting that the alphabetic representation is ordinal and unidirectional.     

Career indecision in adult women: A comparative and descriptive study

This study compared 66 high-school women, 66 first-year college women, and 66 adult women on four measures of career indecision, the Satisfaction with Career Scale, the Occupational Alternatives Question, the Vocational Decision Making Difficulty Scale, and the Career Decision Scale. The results consistently suggested that the adult women were experiencing more career indecision than the high-school and college women. Intercorrelations among the scales were generally moderate to somewhat low and raised some questions about the use of the Career Decision Scale with adult women. Additional data were gathered on the adult women in an attempt to delineate the sample. Variables included were: marital status, present work experience, the career-related goals and the reasons for pursuing these goals, and possible impediments to reaching the goals. These results are presented and the implications for future research and counseling with adult women are examined.     

Case specificity of the stimulus probability effect

Four memory scanning experiments investigated the effect of the probability of occurrence of one case of a letter (e.g., “A”) on response time to the other case of that same letter (“a”). There was no effect: Responses to one case of a letter did not depend on the probability of occurrence of the other case of the letter. This finding indicates that facilitation of visual encoding by high probability of occurrence is not caused by increased activation at the level of the name code. Previous results rule out the possibility that facilitation occurs at the level of feature detectors responding to the individual visual features of the high-probability stimuli, and these results were replicated in the present experiments. It appears that facilitation is caused by activation along specific routes by which visual features activate letter names. This conclusion has implications for the locus of effect of stimulus probability in models of letter coding     

Hyperlexia as a variant of developmental language disorder

Memory and associative reasoning skills of 10 hyperlexic children are examined. The results suggest superior visual and isolated auditory memory skills along with impaired associative language ability. The results are discussed in relation to various theories of hyperlexia.     

A prospective naturalistic study of the impact of an intensive medical treatment on the social behavior of child and adolescent cancer patients

The impact of intensive chemotherapy and prolonged hospitalization on the social behavior of child and adolescent cancer patients was assessed. Twenty-three patients, aged 18 months to 21 years, were observed while they received chemotherapy in a protected environment or in a regular hospital room. Single-subject analyses were used to examine changes on six behaviors in relation to changes in physiological status. Fourteen patients showed significant change in the frequency of at least one behavior. Play and sleep were the behaviors most likely to change. The changes began to occur as patients experienced the systemic toxic effects of the drugs, although a dissipation of drug toxicity generally was not accompanied by a corresponding behavior change. The findings are discussed in relation to age-developmental and interindividual heterogeneity in response to treatment.
