Youthful smokers have been described as extroverted and peer-involved, whereas older smokers are often characterized as depressed and withdrawn. Recognizing this contradiction, we examined cross-sectional and prospective associations between smoking and personality and social constructs assessed every 4 years in a sample (N= 461) originally recruited in junior high school. At Time 1, smoking was positively related to good social relations, extroversion, friends' cigarette use, and cheerfulness. At Times 2–4, smoking was positively related to depression and friends' cigarette use, negatively correlated with good Social Relations, and unrelated to extroversion. Cigarette use was stable over time, but least stable between Times 1 and 2. Findings suggest the instability of early social smoking with peers; those who persist may smoke for tension reduction and self-medication. 相似文献

Male rats, 90-100 days old, with frontal cortex lesions were given either subcutaneous sterile water (SW) as a vehicle control or 1, 10, or 100 micrograms of BIM-22015 every other day for 20 days. Brain-injured subjects tested in the Morris water maze with either 10 micrograms BIM-22015 or SW took significantly more trials than sham-operated rats to locate a submerged platform eight consecutive times within 60 s. The animals given 1 or 100 micrograms BIM-22015 took significantly fewer trials to reach criterion than brain-injured animals in the other drug treatment groups. On a percentage of savings, measured 8 days after reaching criterion, the brain-injured subjects given 1, 10, or 100 micrograms BIM-22015 did not differ from sham-operated rats. In contrast, the brain-injured animals given SW took longer to find the submerged platform than they did during the initial training. To assess long-term effects of the ACTH analog treatment, rats were trained on a delayed spatial alternation task 30 days after receiving the last injection. On this task, brain-injured rats treated with the 10-micrograms dose performed significantly better than those given sterile water. Acetylcholinesterase (AChE)-labeled neurons counted in the nucleus basalis magnocellularis indicated that rats with frontal cortex damage given the 10-micrograms treatment did not differ from the sham controls and had significantly more AChE-positive neurons than injured counterparts treated with SW or 100 micrograms. 相似文献

Family therapies which aim to begin treatment in the first session leave the practitioner at a disadvantage regarding the collection of demographic, historical, and genealogical data that may be useful as treatment proceeds. Not wanting to disrupt interactional reciprocity and flow, the therapist cannot perform methodical anamnesis. The Self-report Family Data Form is presented for collecting useful biographical data from families in treatment without interfering with the clinical interaction. 相似文献

Subject/observers were accurate in identifying emergent leadership hierarchies on four leadership dimensions when provided records of target groups' meetings containing only verbal communications, only nonverbal communications, or both types of behavior. With knowledge of participation rates controlled by covariance, the subject/observers' accuracy scores retained significance in three of the information conditions demonstrating the presence of verbal and nonverbal leadership cues independent of participation rates. The value of verbal and nonverbal communications to identifying leaders varied with the type of leadership hierarchy being identified. The findings are presumed to hold for leader selection as well. The author proposes that the question of why a group member has emerged to fulfill a leadership role in a group be studied from the point of view of group members' selecting leaders or permitting emergence rather than leaders emitting behaviors. 相似文献
