Smári, J., Rúrik Martinsson, D., & Einarsson, H. (2010). Rearing practices and impulsivity/hyperactivity symptoms in relation to inflated responsibility and obsessive‐compulsive symptoms. Scandinavian Journal of Psychology, 51, 392–397. The aim of the study was to investigate potential precursors of inflated responsibility (responsibility attitudes) and obsessive‐compulsive (OCD) symptoms. It was argued that both parental overprotection and impulsivity, separately and in interaction with each other, contribute to inflated responsibility and OCD symptoms. In a large sample of young adults (N = 570), self‐report measures of OCD symptoms (OCI‐R), responsibility attitudes (RAS), anxiety/depression (HADS), rearing practices (EMBU), present and past impulsivity/hyperactivity symptoms (IMP/HY) were administered. Overprotection as well as IMP/HY were found to predict OCD symptoms as well as inflated responsibility. Finally, a significant interaction was found between IMP/HY and overprotection with regard to both OCD symptoms and inflated responsibility. This effect reflected that IMP/HY was more strongly related to OCD symptoms and responsibility in people who had not been overprotected than in people who had been. Conversely overprotection was related to OCD symptoms and responsibility in people low but not in people high in IMP/HY. The results seem to indicate that the inadequacy between offer and need for parental control may play a role in the development of OCD symptoms. 相似文献

The goal of the study was to provide evidence that the production of 50-kHz calls by adult rats is driven by potential or direct social contacts. The calls have been studied during daily visits to a cage by single or paired rats. Repeated exposure of rats to the cage frequently visited by other rats or direct contact between rats significantly increased the number of 50-kHz calls. The increase in production of 50-kHz calls was reduced by 78% after intrapreoptic-anterior hypothalamic injection of MK-801, an N-methyl-D-aspartate-type glutamate receptor antagonist. Calls emitted in all situations had a similar acoustic profile. It was found that 50-kHz calls were produced in anticipation of, and/or during, direct social contacts among adult rats and were predominantly initiated by olfactory stimuli. The calls seem to express an appetitive behavioral state in which the central glutamatergic mechanism is implicated. 相似文献
