Previous research indicates that children from violent marriages are more likely to suffer from conduct problems and/or anxiety disorders than children from nonviolent, satisfactory marriages. However, knowledge regarding specific factors present in violent marriages relating to child problems is limited. The present study examined the relationships involving interspousal aggression, parent-child aggression, and child behavior problems in a sample of 45 children from maritally violent families. Mothers indicated how often their children witnessed interspousal aggression and were victims of parent-child aggression. Mothers also rated their children's problem behaviors while children reported on their own depressive symptoms. The witnessing of interspousal aggression was highly associated with parental aggression directed toward children. Parent-child aggression related to attention problems, anxiety-withdrawl, motor excess, and conduct problems in children. However, the witnessing of interspousal aggression was not significantly related to child behavior problems. These results are consistent with theoretical predictions linking marital problems to child behavior by virtue of their association with parenting.This research was supported in part by a Grant-in-Aid of Research awarded to the first author by Sigma Xi, the Scientific Research Society, and NIMH Grant No. MH35340 awarded to the third author.

By varying what we take to be the saliency oflandmarks (which are cues to location and orientation that are unique and visible from a distance), the slopes and intercepts of the time/angle function in the "mental rotation" task were caused to vary accordingly. 相似文献

The relationship between the “permanence” of a person's occupancy of a place and his territorial behavior were tested in a field setting. The permanence (past residence and anticipated future residence) of suburban residents who displayed territory defenses was compared to that of control residents who had no such displays. It was found that people who had visible territorial displays on the property showed greater permanence in attachment to the property and responded more rapidly to the presence of an outsider on their property. Results were discussed with reference to the functional implications of territoriality in communities. 相似文献

It is shown that invariance requirements remove the indeterminacy in factor determination and lead to an integration of factorial studies with promise of considerable reduction in computational labor. The selection of significant primary factors is discussed, with special reference to Thurstone's simple structure criterion. 相似文献

There are both genetic and behavioral risk factors for breast cancer, but the interaction between these factors is not clear. Little is known about the impact of receiving genetic risk information for breast cancer on behaviors such as diet and physical activity. Seven focus groups were conducted with 23 women who had recently received genetic counseling for breast cancer, in order to explore health beliefs and behaviors following genetic counseling. Findings revealed that there was much confusion and uncertainty about the associations between health behaviors and breast cancer risk, and participants reported that receiving genetic counseling had little impact on health protective behaviors. Further research is required to understand variation in response to genetic risk information, and to assess the impact of providing additional information regarding lifestyle factors. 相似文献

Summary knowledge of results (KR) involves the presentation KR for each of a set of trials (e.g., 10) only after the last trial in the set has been completed. Earlier, Lavery (1962) showed that, relative to providing KR after each trial, a 20-trial summary KR was detrimental to performance in a practice phase with KR present but was beneficial for a no-KR retention test. Using a relatively simple ballistic-timing task, we examined summary lengths of 1 (essentially KR after every trial), 5, 10, and 15 trials, searching for an inverted-U relationship between summary length and retention performance as predicated by a guidance hypothesis for KR. During acquisition when KR was present and being manipulated, all groups showed improvements in performance across practice, while increased summary lengths generally depressed performance. However, in a delayed no-KR retention test, there was an inverse relation between the summary length in acquisition and absolute constant error on the retention test. A guidance hypothesis is favored to explain how, relative to immediate KR, long KR summaries can provide detrimental effects in acquisition while enhancing retention performance. 相似文献

The purpose of the present study was to evaluate the predictive validity of the Yellow Brick Road Test (YBRT) relative to performance in reading as measured by the Metropolitan Achievement Test (MAT). A full prediction-performance comparison matrix was employed to compare three different cutoff scores for the YBRT for the identification of “at-risk” children. Four hundred and fourteen kindergarten-aged children were administered the YBRT, 214 of whom were followed to the end of second grade. It was concluded that the YBRT is a moderately valid instrument for predicting the level of reading achievement in a population with a different average performance level from the normative sample. However, the results of this study failed to support the utility of the test author's suggested use of a score of 120 as the cutoff score. Finally, it is recommended that a prediction-performance comparison study be considered standard methodology for the evaluation of the validity and efficiency of screening instruments. 相似文献
