The present study compared Turkish University students' and middle-aged adults' developmental theories about the perceived importance of needs related to different life tasks and functionality of relationships with parents, same-sex siblings, and friends for need satisfaction during childhood, adolescence, and youth. A retrospective method was used. The following results emerged: (1) the importance of needs related to a search for identity and intimacy increased and the importance of those related to dependency decreased from childhood to adolescence; (2) needs related to intimacy maintained a high level of importance during youth whereas importance of the need for self-understanding/development decreased from adolescence to youth; (3) increases in the perceived importance of friends occurred between childhood and adolescence, especially with respect to needs related to identity and intimacy issues; (4) decreases in the perceived importance of parents were reported between adolescence and youth, especially with respect to needs related to identity, intimacy, and dependency; (5) developmental theories of groups and sexes did not differ; (6) group and sex differences with respect to importance ratings of some needs emerged. 相似文献

We have recently reported a correlation between schizophrenialike symptoms and the degree of pseudoneglect in healthy right-handers. We aimed to investigate the effect of familial sinistrality (FS) on this relation. Seventy-six healthy right-handers were divided into four groups on the basis of gender and FS. A computerized version of Corsi's task was used as the visuospatial task. Subjects filled in the Magical Ideation Scale (MI), which asked for delusionlike beliefs, and performed the Corsi's task using each hand. Performance of both hemispaces was separately evaluated. In all groups, performance of the left hemispace was better than that of the right hemispace and FS+ subjects performed better than FS- subjects. When the right hand was used, performance was correlated to MI scores only for FS- groups. Findings suggest that the correlation between right-sided neglect and proneness to schizotypy in normal right-handers is affected by FS. 相似文献

The present study aimed to investigate the determinants of stress-related growth. For this aim the associations of gender,
stressfulness of the event, and three coping strategies (problem-oriented, fatalistic, and helplessness) with stress-related
growth were tested by multiple regression analysis. Participants were 132 undergraduate students. Results revealed that females
reported higher levels of stress-related growth than males, and as expected, higher levels of the stressfulness of the event
associated with more stress-related growth. Furthermore, frequent utilization of problem-oriented and fatalistic coping strategies
was associated with higher stress-related growth. These findings were discussed in the light of relevant literature and culture-specific
features.

The nucleus accumbens (NAcc) has been shown to play a role in motor and spatial learning. Protein kinase C (PKC) has been implicated in the mechanisms of initiation and maintenance of long-term potentiation that is thought to be involved in the storage of long-term memory. In the present study, the importance of de novo synthesis of PKC-gamma within the NAcc in the acquisition and retention of spatial discrimination learning was assessed using an antisense knockdown approach. Separate groups of Long-Evans rats were exposed to acute microinfusions (6microg/microl) of PKC-gamma antisense oligodeoxynucleotide (AS-ODN), control oligodeoxynucleotide (C-ODN) or vehicle into the NAcc at 24 and 3h before each training session. Behavioral findings showed that the blockade of NAcc-PKC-gamma translation caused impairments in the early phase of learning and retention of spatial information. Biochemical experiments showed that PKC-gamma expression was reduced and Ca(2+)/phospholipid-dependent protein kinase C (PKC) activity was blocked significantly in the AS-ODN-treated rats in comparison with control rats. The present findings suggest that NAcc-PKC-gamma plays a role during the early acquisition of spatial learning. Also, retention test results suggest that NAcc-PKC-gamma may be working as an intermediate factor involved in the onset of molecular mechanisms necessary for spatial memory consolidation within the NAcc. 相似文献

This paper attempts to define the concept of placebo as it is used in the clinical context The author claims that X is a placebo
if and only if X has such a property dp, that whenever in a therapeutic situation T a stimulus S appears, then in attending conditions A, it will cause a beneficial
reaction R in the patient. Formally, the same structure may be used to define any pharmacologically active drug. The main
difference between the drug and a placebo is in the range of possible substitutions for X and the property d. For the active
drug there is only one possible substitution for X and property d and it can be scientifically explained why, and how the
drug works. In the case of a placebo a set of possible substitutions for X and d is open, and so far it is impossible to offer
any scientifically valid explanation of the action mechanism of placebo. 相似文献

The study examines whether self-efficacy mediates between intention and behavior, and whether appearance norms and self-efficacy are additive or synergistic predictors of sunscreen use. At two measurement points in time, 14 weeks apart, 154 individuals responded to an online questionnaire. Moderated mediation was tested by hierarchical regression analyses. Self-efficacy mediated the intention-behavior relationship, whereas appearance norms emerged as a moderator of the self-efficacy-sunscreen use relationship. The model accounted for 22% of the behavior variance at time 2. For individuals who believe that they would look more attractive with a tan, self-efficacy did not have a strong effect on behavior. Thus, for skin-protection motivation to become effective, self-efficacy is needed in conjunction with less positive appearance norms. Implications for public health promotion and mass media sunscreen use campaigns are discussed. 相似文献

Although past research provided some clues about the relation of language use with mental health, the mediatory functions of personality variables in this relationship have been ignored. This research examined the mediatory role of self‐concept clarity in the relationship between language use perceived by individuals and mental health indicators including anxiety, depression, and alexithymia. Based on the theoretical framework suggested by ?im?ek (2010), two studies sought to test two alternative structural equation models in data from university students in the first study (n = 250) and data from other groups in the second study (n = 331). The first model assumed that the relationship of language use with anxiety, depression, and alexithymia was mediated by self‐concept clarity. The second model tested the mediatory role of both anxiety and self‐concept clarity in this relationship. The results of the first study showed that the second model fitted better to the data than the first. Consistent with the first study, the results of the second study confirmed that the second model produced better goodness of fit statistics than the first model. 相似文献

Presently, little is known about the effect of curved backgrounds against which the target stimulus is presented on precision in stereoacuity. The experiment analyzed the influence of stimulus orientation and 3D background configuration on stereoscopic vision. Participants were instructed to perform 3D visual alignment tasks on a modified version of the Howard-Dolman apparatus, whereupon precision in depth perception for different curved backgrounds (flat, black, concave, and convex) was evaluated. In addition, the influence of stimulus orientation (0 degrees, 45 degrees, and 90 degrees) on precision was examined. The findings revealed an underestimation in the perceived depth in all background configurations, indicating highest and lowest precision outcomes for convex and concave backgrounds, respectively. In addition, a significant interaction of background and orientation was found. It was concluded that, in a real environment, background local depth cues are integrated with target stimuli to contribute to depth perception. 相似文献
