This paper seeks to clarify the association between the intimacy and the magnitude of relational uncertainty generated by specific events within romantic relationships. More specifically, we suggest that episodic relational uncertainty peaks at moderate levels of intimacy. We conducted a cross–sectional study in which 328 romantic relationship participants reported their reactions to a hypothetical relational uncertainty increasing event. Although the effect size was small, findings documented a curvilinear association between intimacy and episodic relational uncertainty. Further, hierarchical regression results supported our predictions about the effects of intimacy and episodic relational uncertainty on people’s reactions to the events. We discuss the implications of our findings for understanding the roles of both intimacy and episodic relational uncertainty within romantic relationships.  相似文献

The authors investigated dual relationships between 2 groups of staff (direct care and professional) and adolescent clients in 2 residential treatment programs. Staff were surveyed on their behavior and corresponding ethical beliefs regarding interactions they believed to be acceptable with minor clients specifically at termination of the treatment program. Direct care staff were more likely than were professional staff to have inconsistencies in behaviors and ethical beliefs. The American Counseling Association's (1995) Code of Ethics would prohibit some of the staff beliefs regarding acceptable behavior. Both groups were uncertain about the ethical appropriateness of certain interactions with adolescent clients. Implications are discussed.  相似文献

In rodents stress impairs delay as well as trace eyelid conditioning in females, but enhances it in males. The present study tested the effects of acute psychosocial stress exposure on classical delay eyeblink conditioning in healthy men and women. In a between subject design, participants were exposed to psychosocial stress using the Trier Social Stress Test (TSST) or a control condition which was followed by a delay eyeblink classical conditioning procedure. Stress exposure led to a significant increase in salivary cortisol and impaired acquisition of conditioned eyeblink responses (CRs). This was evident by a later first CR and an overall lower CR rate of the stress group. The stress-induced acquisition impairment was observed in both women and men. Subjects failing to show a stress-induced cortisol increase (cortisol non-responder) were not impaired in acquisition. Our findings indicate that acute stress, possibly via activation of the hypothalamus–pituitary–adrenal (HPA) axis, reduces the ability to acquire a simple conditioned motor response in humans.  相似文献

Teaching is a powerful form of social learning, but there is little systematic evidence that it occurs in species other than humans. Using long-term video archives the foraging behaviors by mother Atlantic spotted dolphins (Stenella frontalis) were observed when their calves were present and when their calves were not present, including in the presence of non-calf conspecifics. The nine mothers we observed chased prey significantly longer and made significantly more referential body-orienting movements in the direction of the prey during foraging events when their calves were present than when their calves were not present, regardless of whether they were foraging alone or with another non-calf dolphin. Although further research into the potential consequences for the naïve calves is still warranted, these data based on the maternal foraging behavior are suggestive of teaching as a social-learning mechanism in nonhuman animals.  相似文献

Background Shayer, Ginsburg, and Coe (2007) showed that children leaving primary school in Y6 entered secondary school with much lower levels of understanding of the physical conservations than in 1976. It seemed desirable to investigate cognitive development in the first three years of secondary education. Aims By using two Piagetian tests of formal operations, one of which had been used in the 1976 CSMS survey, the performance of Y8 and Y9 pupils would be compared with the survey results published in 1978. Sample Eight schools were selected as willing to test their Y9 or Y8 classes on either the Pendulum (in 2007) or the Equilibrium in the Balance tests (in 2006), giving 39 classes on which to make the comparison with 1976 performance. Method Regression of the pupils' class mean on each formal test on either the class's 2004 MidYIS or nferCAT standardized scores, and computing the regression at IQ = 100 allows comparison with that found in 1976. Results On Equilibrium in the Balance the Y8 pupils were down on the proportion at the early formal level or above by ?0.61 standard deviations (SD) for boys and ?0.63 SD for girls on the 1976 results. On the Pendulum the Y9 boys were down by ?0.49 SD and the girls by ?0.48 SD on the proportion at the early formal level or above. Conclusion The negative Flynn‐effect found on Volume & Heaviness for Y7 pupils is paralleled by a similar negative effect on attainment of formal operations by Y8 and Y9, compared with 1976. Yet at the same time the proportion of pupils using the top level of concrete operational thinking has increased on both tests. It seems that there has been a change either in general societal pressures on the individual or in the style of teaching in schools – or both – favouring a lower level of processing of reality.  相似文献

Research on risk-taking behavior has shown to yield inconsistent findings. Three studies were conducted using four different analysis techniques. The first study used a phenomenological approach and qualitative analysis to gain an understanding of risk-taking. A model of factors relating to risk-taking was developed and tested in a second study. The third study was conducted to develop scales of risk and used magnitude estimation and multidimensional scaling techniques. Results from the studies confirmed the multidimensionality of the construct of risk-taking. Also indicated was a gender difference in risk-taking behavior and perception. These studies expand our knowledge of risk-taking behavior in that 1) a method of categorizing risks was developed, 2) gender similarities and differences in risk-taking were explored, and 3) perceived magnitude and underlying dimensions of risk were developed.  相似文献

Children and adults were escorted on their first walk across our university campus and were periodically led off the original route during the return trip. During the return, we stopped prior to intersections on and off the original route to obtain estimates of place recognition accuracy and confidence. The subjects were then asked to point to the path that led back to the start and were corrected if wrong. Accuracy of place recognition was intermediate in a way-finding task requiring reversal of an incidentally learned novel route. However, accuracy increased as subjects were farther from the original route, indicating that the presence of novel landmarks boosted the discrimination of old and new places. Eight-year-old children were less accurate than 12-year-old children and 25-year-old adults, who did not differ in accuracy. There was a similar age difference in the ability to point to the direction to return when subjects correctly recognized that they were off route. The results are used to develop a model of way finding by place recognition.  相似文献

Both researchers and therapists stress the importance of integrating different forms of psychotherapy. Integration may be achieved in three ways. Supporters of the “empirical strategy” believe that more research is the solution. Followers of the “conceptual strategy” try to theorize on psychotherapy using psychological and sociological concepts. Other researchers see a “linguistic strategy” as the way to achieving a better understanding of psychotherapy. Whether any of these strategies will enable us to increase our insight into psychotherapy is questionable. All focus on technical aspects, that is, on the means to achieve effects. Yet, therapeutic effects cannot be understood unless they are interconnected with diagnostics. This paper argues that an integrated theory should be developed which includes diagnostics and treatment and which is supported by a theory on psychological (dys)functioning.  相似文献
