Letter naming time,digit span,and precocious reading achievement

In two 6-month longitudinal studies of intellectually advanced preschool children, letter naming time and backward digit span were moderately good predictors of concurrent reading achievement (PIAT Reading Recognition Score). None of the remaining measures in a battery of standard cognitive indices, including Stanford-Binet MA, was associated with reading achievement. The results of cross-lagged correlation analysis of data from one of the two samples suggested that individual differences in time to access name codes for visual stimuli predict, but are not a consequence of, individual differences in reading achievement. The results of the cross-lagged analysis for the second sample were inconclusive. As a whole, the results are consistent with findings from other populations indicating that both short term memory span and efficiency of retrieval from long term memory are related to reading ability. The results also indicate, however, that the relationship between retrieval efficiency and reading achievement in precocious readers cannot be described by extrapolation of threshold estimates from the performance of older, unselected groups of readers.     

BEHAVIORAL ASSESSMENT FOR PEDIATRIC INTENSIVE CARE UNITS1

Two studies were conducted to analyze behaviors of staff and patients on a Pediatric Intensive Care Unit (PICU). In the first study, behavioral observation procedures were employed to assess patient state, physical position, affect, verbal behaviors, visual attention and activity engagement, and staff verbal behavior. On the average, one-third of the patients were judged to be conscious and alert but markedly nonengaged with their environment. In the second study, a member of the hospital staff provided alert patients with individual activities to determine whether a simple environmental manipulation could positively affect behavior of children in intensive care. Employing a reversal design, the activity intervention was found to increase attention and engagement and positive affect, and to decrease inappropriate behavior. Both studies demonstrate that behavioral assessment procedures can provide an empirical basis for designing PICU routines affecting children's psychosocial status, and, thus, complement current procedures designed to provide quality medical care.     

Imaging,empathy, and causal attribution

Three studies were conducted to test whether imagery accounts for the effects of empathy on attributions, that is, whether attributers construct and scan a mental image of social scenarios the same way that actual participants scan a real environment. According to this interpretation, attributers “see” the world as the participant does and make vicarious attributions. An alternative interpretation holds that subjects base vicarious attributions on recreating the motivations and affect of the actor, so that imaging is irrelevant to empathy and attributions. In the first study, subjects who imagined a story from the perspective of a particular character later showed differential recall of story details as a function of role, but not differential attributions. In Experiment 2, role-taking subjects showed clear effects of imaged perspective on recall for story details, but no effects on attributions of causality for an accident. Further, recall and attribution were uncorrelated. In the last study, empathy and imagery role-taking instructions produced independent effects: imagers showed pronounced perspective-relevant recall and empathizers did not. Neither showed unambiguous vicarious attributions. Recall and attribution were again uncorrelated. These studies suggest that the imagery explanation of empathy effects is untenable, and imply that the recall of perspective-relevant details is unlikely to mediate attributions of causality in imaginary scenarios.     

Menstrual cycle affects kinesthetic aftereffect, an index of personality and perceptual style

Research suggests that kinesthetic aftereffect (KAE) scores reflect status on a postulated stimulus intensity modulation (SIM) mechanism that damps down subjective stimulus intensity for some (reducing) and increases it for others (augmenting). Such a mechanism would help account for empirically observed individual differences in such behaviors as pain tolerance, sensory deprivation reactivity, and stimulation seeking. It was hypothesized and confirmed in three adult female samples that KAE varies curvilinearly over the menstrual cycle: Greater KAE reduction occurs at the cycle's beginning and end. Neither tiredness, oral contraception, medication, attention, nor social expectations can explain this finding. Of the behaviors studied in the KAE literature, only five are also encompassed by the menstrual cycle literature. Four of these (antisocial behavior, acute schizophrenic episodes, accidents, and activity level) show similar curvilinearity over the cycle. We hypothesize that cyclical variation in the SIM mechanism mediates the curvilinear pattern observed for both these four behaviors and KAE.     

Coactor's behavior and imitative aggression

After being exposed to either an aggressive or a nonaggressive filmed model, four- and five-year-old boys were tested for imitation while either alone or with a confederate who had also seen the film. The confederate's behavior was either inactive, the same as that in the film, the same as that in the film the child had not seen, novel but of the same category (aggressive or nonaggressive) as that in the film seen, or novel but in the category of the film not seen. These conditions conformed to the dimensions of a 2 × 6 factoral design. According to prediction, the imitation of subjects exposed to the aggressive model was greatest when the confederate's behavior was similar to the model's. No difference in imitation was produced by the confederate's actions if the boy had watched the nonaggressive model. The results were interpreted within the context of social comparison theory.This project was facilitated by the senior author's Margaret Bosshardt Pace and Paul David Pace Research Fellowship.     

A Peer Assertiveness-Training Program

The demand for assertiveness-training groups and the effective use of paraprofessionals in skills training were influential factors in the authors' decision to develop a peer assertiveness-training program. This program extends the availability of assertiveness training to students through the use of paraprofessionals as group leaders. This article describes a format for developing a peer assertiveness-training program and is based on the authors' experience conducting this program during the 1977–78 academic year at Pennsylvania State University.     

Free recall of abstract and concrete words by American and Ghanaian college students

This investigation compared the free recall of concrete and abstract words in American and Ghanaian college students. There were no differences in the total number of words recalled as a function of concreteness or culture. However, recall of concrete words showed a greater improvement across trials for both cultures. Although there was no difference in the amounts of subjective organization exhibited by Ghanaian and American students, there was evidence for a greater serializing tendency among American students. It appears that the major cultural differences typically observed in African-American comparisons of free recall may be overshadowed by increases in the educational level of the subjects.     

Conservation training in four-year-old children

In Experiment 1 two training procedures were used to teach four-year-olds to conserve. Verbal rule instruction consisted of providing verbal rules and demonstrations of the operations referred to by the rules. Feedback consisted of providing verbal feedback contingent upon the children's responses. One week after training on conservation of number and length the children were given a posttest which included tests of conservation of number, length, and mass. Children who were given verbal rule instruction conserved significantly more on the number and length posttest problems than children who were not. However, this learning did not transfer to the mass problems, possibly because mass is not naturally acquired until some time after conservation of number and length. The feedback training procedure had no effect on conservation performance. In Experiment 2, the verbal rule instruction procedure was used to train four-year-olds on conservation of length and mass. One week after training the children were tested on both conservation of number, which is typically acquired before length and mass, and conservation of weight, which is typically acquired after length and mass, as well as on conservation of length and mass. Children who were given training conserved more on all four types of problems than children in the control group.
