How Do Sibling Conflicts End?

The endings of sibling conflicts were investigated in 40 families at 2 time periods. Each family included 2 children, studied when they were 2 1/2 and 4 1/2 years of age, and 2 years later, at 4 1/2and 6 1/2 years. Four types of conflict endings were observed in sibling conflicts: Compromise, Reconciliation, Submission, and No Resolution. Results indicate that at both time periods conflicts typically ended with No Resolution, followed by Submission, Compromise, and finally, Reconciliation. Submissions decreased and No Resolutions increased over the two time periods; no changes were observed in either Compromise or Reconciliation. Parents' interventions led directly to a resolution of 16% of the children's disputes (Parent Ending). In those cases, there was a greater likelihood of conflicts ending in Compromise or Reconciliation than when parents did not intervene. Conflicts in which parents intervened but the children ultimately resolved the conflicts themselves (Child Ending with Intervention) occurred 42% of the time. Such conflicts ended more often with No Resolution and less often with children's Submissions to their siblings. The implications of these findings for the development of children's conflict resolution skills and the role of parent involvement are discussed.     

Perseveration of associative strength in rabbit nictitating membrane response conditioning following ISI shifts

The present experiment determined whether associative strength based upon 15 CS-US pairings at various interstimulus intervals (ISIs) could survive shifts of the ISI to influence the subsequent acquisition of the nictitating membrane (NM) CR. The choice of 15 preshift pairings was based upon previous work, which had shown that this training level produced substantial associative strength without NM CR acquisition. Consequently, this experiment, by shifting the ISI before the beginning of CR acquisition, served as an extension to traditional ISI-shift studies that have imposed the manipulation after CR acquisition. The findings of the experiment indicated that 15 preshift pairings in Stage 1 at ISIs from 250 to 4,000 msec were as effective as 15 pairings at a 500-msec ISI in determining the number of trials to the first NM CR in Stage 2 in which the training ISI was 500 msec. Moreover, 15 pairings in Stage 1 at ISIs from 250 to 2,000 msec were equivalent to 15 pairings at 500 msec in controlling the number of trials to 10 successive NM CRs in Stage 2. These outcomes demonstrate that, within a large ISI range, the associative strength based upon relatively few pairings is preserved despite various shifts of the ISI. Therefore, these results suggest that the reductions in CR performance, which have been consistently observed in traditional studies following ISI shifts, are not due to the loss of associative strength.     

Technique and timing in women's inward two and one half somersault tuck (405C) and the men's inward two and one half somersault pike (405B) 3 m springboard dives

The purpose of this study was to compare the inward two and one half somersault dive in a tuck position (405C) performed by females (n = 22) and the inward two and one half somersault dive in a pike position (405B) performed by males (n = 24) to determine changes required by females to successfully perform 405B. Key performance variables in inward dives were also compared to those of backward dives. Video data of the dives performed at the 1999 FINA World Diving Cup were captured and digitized to obtain times and postures of the divers at specific events including takeoff and entry. Estimates of flight height and mass-normalised work done on the springboard were obtained from flight times. Some females worked the springboard strongly enough to generate sufficient height and rotation to perform 405B. Males performed 405B comfortably because they achieved better height and rotation than the females. A comparison of backward and inward dives revealed that divers are able to attain greater height in backward dives than inward dives.     

Visual stimulation using microcomputers

ABSTRACT

The dominant approach to the education of young visually handicapped children currently hinges on the idea of encouraging the use of sight through visual stimulation. This takes various forms, including the optimization of the child's visual environment, training children to use their sight efficiently, and photo‐stimulation to alter the early development of the brain. It is argued that microcomputers have an important part to play in providing visual stimulation. VDU monitors can present materials in a ‘back‐lit’ manner, avoiding the problem of occlusion of the light source. Moreover, input devices such as the touch‐sensitive screen allow children to interact directly with the images on the computer screen, ensuring that the visual stimulus received is related to their own actions.     

Psychotherapy as a model for interpersonal dynamics in tertiary teaching

The similarity of process in psychotherapy and in the interpersonal dynamics of tertiary teaching is of interest in attempting to maximise student interest and success. This article reviews the similarities in predictors of positive outcome in both psychotherapy and tertiary education, and suggests that the two processes have a great deal in common. This suggestion is tested by comparing the personality variables (as measured by the Adjective Check List) which predict success in two dissimilar medical courses, Physical Chemistry and Counselling Skills. Results indicate that, in both courses, variables which predict success include aspects of personal adjustment and intellectual style which also would predict success in psychotherapy. It is concluded that the interaction of personal and interpersonal factors in success in tertiary courses may be based on similar processes as success in psychotherapy, and that these processes warrant further research.
