Gender differences,mediation, and disciplinary styles in children's responses to television

A sample of kindergarten and first-grade children was studied in a research center and at school to determine the extent to which family communication mediated their comprehension of television, as well as a series of cognitive skills necessary for such comprehension. Separate analyses were conducted for boys and girls, and results indicated that certain styles of family mediation facilitated comprehension more effectively for boys than for girls. Additionally, differential effects of two styles of discipline were found for each sex.This research was funded by a grant to Jerome and Dorothy Singer from the John D. and Catherine T. MacArthur Foundation entitled Television and Family Living Patterns.     

Conditioned activity and the interaction of amphetamine experience with morphine's activity effects

This experiment assessed the transfer effect of Pavlovian conditioning with d-amphetamine sulfate (1 mg/kg) on morphine's activity effects. Prior experience with amphetamine resulted in higher levels of activity when challenged with morphine (10 and 20 mg/kg). This interactive effect of amphetamine, however, was present only in those animals who had experienced amphetamine paired with the activity test situation. Animals who had received equivalent doses of amphetamine unpaired with the testing environment did not differ from drug-naive control animals. Analysis of predrug activity levels revealed a conditioned activity response in paired animals compared to the controls. These findings suggest that the response interaction between drug conditioned responses and drug unconditioned responses is an important determinant of cross-drug effects between drugs of different pharmacological classes.

A comparison of “traditional” and “atypical” workers: Demographic,behavioral, and attitudinal differences

Differences among full-time (n=1066), part-time (n=132), and moonlighting employees (n=153) in a variety of occupations were examined. Moonlighters as compared to full-timers were younger, more frequently male, perceived less educational fit with their main jobs, and were primary wage earners. Full-timers as compared to part-timers were more frequently male, married, and primary wage earners. Part-timers had the greatest turnover, but no differences were detected for other withdrawal behaviors. Part-timers were more satisified with working conditions but were less satisfied with extrinsic rewards and life in general. Moonlighters expressed a stronger work ethic and placed less importance on working conditions.A version of this paper was presented at the 1991 Meetings of the Southwest Division of the Academy of Management in Houston, TX.     

Coordination dynamics of rhythmical and discrete prehension movements: Implications of the scanning procedure and individual differences

The aim of this study was to compare the coordination dynamics of discrete and rhythmical reaching and grasping movements from a dynamical systems perspective. Previous research from this theoretical perspective had focused on rhythmical actions and it is unclear to what extent discrete movements are amenable to a similar dynamical systems analysis. Six adult subjects performed prehension in two conditions: a discrete, non-continuous mode and a rhythmical, continuous mode. A `scanning procedure' was implemented between pre- and post-tests in which the required time of final relative hand closure (T_rfc) was systematically varied. It was shown that the error in the reaching and grasping pattern was least at an attractor region and systematically increased with deviation from the attractor. Results also indicated that there were no differences between condition or trial block for the group. However, there were several within-subject effects of interest. The validity of the scanning procedure was found to be questionable in the discrete condition, where four subjects showed differences in T_rfc between pre- or post-test and the predicted T_rfc of the scanning procedure. Four out of six subjects also had different preferred T_rfc values for discrete and rhythmical movement, indicating that individual specific models might need to be constructed for future dynamical modelling of discrete movement.PsycINFO classification: 2330     

Cree Conceptions of Cognitive Competence

The study of cognitive competence in various cultures has shifted from examining “general intelligence” (very often only in terms known to Western cultures), to a concern for indigenous conceptions of what it means to be a capable person in that culture. Ethnographic techniques elicited the range of Cree terms for such general competence. With a sample of 60 Cree adults in Northern Ontario (stratified by age and sex), we obtained card sorts for 20 terms (piles sorted on basis of similarity), and semantic differential ratings (on 12 bipolar adjective dimensions), for two of the terms. A two-dimensional solution was obtained using Multidimensional scaling. On one dimension there was a cluster of core terms (e.g. wise, thinks hard, pays attention, respectful, good sense of direction) at one end, and three other terms (stupid, crazy, “backwards knowledge”) at the other. On the second dimension, a pair of terms translated as “mentally tough” (with implications of perseverance, stamina, bravery) was at one end, and two other terms (understands new things, religious) were at the other. The term for “lives like a white person” was opposite the core cluster of terms for Cree competence. Ratings of the two terms (“wise” and “understands new things”), indicate that both are associated with: Taking time, good, hard-working, careful, patient, self-sufficient, strong, developing, bush-related, and easy to see. These results indicate some clear differences from Western notions of intelligence as being fast, analytic and without social or moral dimensions.     

Inhibition of Intermediate-Term Memory Following Passive Avoidance Training in Neonate Chicks by a Presynaptic Cholinergic Blocker

The effects of a specific presynaptic cholinergic antagonist, toosendanin, on memory formation following a passive avoidance training experience in day-old chicks was investigated. Bilateral injection of toosendanin into the neostriatal/hyperstriatal region of the chick forebrain produced memory impairment in a dose-dependent manner. Retention deficits were apparent from 20 min following training in chicks treated with toosendanin, regardless of the injection time relative to training. Chicks that received injections of the drug at corresponding times prior to retention tests showed normal retention levels, suggesting that toosendanin has no effect on performance and memory retrieval. These results indicate an involvement of cholinergic transmission during an early stage of memory formation.
