Dissociations of writing and praxis: Two cases in point

For normal writing it is essential that both motoric and linguistic competence be present; disruption of one or the other of these faculties may result in qualitatively different types of agraphia. Two right-handed patients became agraphic after left hemisphere lesions; pure apraxic agraphia in the absence of limb apraxia developed in one patient and pure linguistic agraphia in association with severe ideomotor limb apraxia in the other. The performance of these patients not only serves to illustrate the dissociation between the motoric and linguistic faculties that underlie writing but also confirms that ideomotor limb apraxia and apraxic agraphia are distinct and dissociable entities.     

The Relationship Between Parenting Behaviour and Ethnic Identity in Chinese-American and Chinese-Australian Adolescents

This study investigated the relationship between four types of parenting behaviour—warmth, control, monitoring, and autonomy-promoting—and two components of ethnic identity—ethnic behaviours/knowledge and ethnic pride—in first- and second-generation Chinese-American and Chinese-Australian high school students. As hypothesized, parenting behaviours did not predict levels of ethnic behaviour/knowledge, but ethnic pride was associated with family environments characterized as warm, controlling, and autonomy-promoting. Neither gender of respondent nor geographical location (United States or Australia) added significantly to the variance in ethnic identity. The study indicates that parenting practices contribute significantly to adolescents' sense of pride and positive evaluation of their ethnic heritage.     

Factors affecting baseline nociceptive sensitivity

The present study examined factors with the potential to affect sensitivity of the tail flick measure of thermal nociception in rats. The length of the habituation period before testing began, the apparatus ramp speed, and the light:dark cycle were manipulated in a within-subjects design to determine which factors minimize the variability between baseline trials. Factors had little effect on mean baseline latencies, but standard deviations were affected. Lower variability occurred after 0- and 15-min habituation periods than after 60-min periods, after a constant light cycle than after a light:dark cycle, and after a higher temperature thermal apparatus than after a lower temperature. Although statistically significant, these effects were modest in size. These results may be of some use to those comparing studies that used very different parameters and to those designing studies and trying to optimize conditions.     

“Hey mom, look at me!”

The degree to which infant and maternal characteristics were related to maternal psychological distress and play competence was examined in 40 mother preterm and full-term dyads. Measures of maternal psychological distress, self-efficacy, infant temperament, and mother-infant interaction in a play situation, were obtained at 4 months corrected for prematurity. Results revealed that maternal self-efficacy was the strongest correlate of maternal psychological distress but was not related to maternal play competence. Interaction effects for unadaptable temperament and infant behavioral involvement were found in the regressions predicting both maternal psychological distress and maternal play competence. Mothers of more adaptable and less behaviorally involved infants reported greater psychological distress and exhibited greater play competence than mothers of more adaptable and involved infants. The results suggest that a lack of concordance between mothers' perceptions of their infants' behavior and actual behavioral experiences adversely affects mothers' affect and the quality of their play interactions.     

Marriage guidance counselling: I. What clients think will help

Thirty-one first-time attenders for marriage guidance counselling were given a non-schedule standardised interview and a client questionnaire. The main aim was to identify the counselling and counsellor characteristics which clients considered would be most helpful in dealing with their problems. Traditional counselling skills such as the ability to be warm, supportive, understanding and a good listener were seen to be important by most clients. However, the vast majority of clients indicated that it would be helpful to receive the counsellor's opinion about their marriage, their personal problems and marriage in general: this is incompatible with a non-directive approach to counselling. Whilst clients may not know best how they should be helped, counsellors who fail to address their preconceptions risk mutual disappointment and premature termination of counselling.     

Sex and age variations in the quality and intensity of children's emotional attributions to hypothetical situations

Sex and age differences in the quality and intensity of children's emotional attributions to affect-laden stories were explored. Seventy-two 7-, 9-, and 11-year-old children, with equal numbers of boys and girls of each age, were individually told 10 affect-laden stories. After each story, children were asked to indicate how they would feel as the story protagonist by pointing to angry, sad, happy, and scared faces, each of which had three degrees of intensity. The results revealed that boys attributed anger to themselves more frequently than did girls; girls attributed sadness and fear to themselves more frequently than did boys. Boys' first responses to the stories were more intensely angry and more intensely happy than were girls' first responses; and the intensity of both boys' and girls' emotional attributions decreased with age.This research was funded by a grant from the Graduate School of Boston University, #GRS-661-PS. The author expresses appreciation to the faculty and students of the Bartlett School, Lowell, Massachusetts, and to the Lowell-Lesley College Teacher Corps Project, especially to Allan Alson, John Cronin, and Edna Robinson. The author would also like to thank Shirley Brody, Emily Flynn, Benjamin Gozun, and Richard Simon for their help in various phases of this project.     

Asymmetry of perception in free viewing of chimeric faces

We have devised a new free-vision task to index functional cerebral asymmetry for processing facial characteristics. Confirming its sensitivity to properties of lateralized hemispheric functions, left- and right-handers were clearly differentiated on this task with respect to several aspects of performance that conform with known differences between handedness groups in hemispheric asymmetry. Additionally, there were highly reliable and stable individual differences in perceptual asymmetries within handedness. Analyses of items in the task revealed that most of the differences between items in the asymmetries they elicited were random.     

Serpent versus surrogate and other determinants of runway fear differences

Avoidance behavior and fear ratings by snake-fearful college volunteers were studied as a function of live vs stuffed snake stimuli, order of presenting the snakes, accompanied (participant modeling format) or unaccompanied social context in the runway test, high or moderate initial fear level and sex of subject. The live snake sponsored more avoidance and rated fear than the specimen, and type of snake stimulus interacted with students' initial fear levels, thus raising questions about previous research using specimens instead of live phobic animal stimuli. Accompanied social context produced generally less fear and avoidance than unaccompanied approach. Numerous complex interactions were found among the type of snake, presentation sequence, social context, sex and fear level variables, raising methodological cautions for future research.
