We sought to determine the extent to which one’s beliefs about the relationship between an employee and an organization at the start of employment influence subsequent socialization activities. The balance of employee exchange relationships, employee perceptions of both their own obligations and the employers’ obligations, were collected from 120 newcomers in a public sector organization on the first day of employment and again three months later. We found the relationship between employee obligations and two socialization activities (time with mentor and time spent in training) depended on the employee’s perceptions of what the employer owed the employee, such that employees in unbalanced relationships tended to engage in more socialization activities than employees in balanced relationships.  相似文献

Though generalization of conditioned fear has been implicated as a central feature of pathological anxiety, surprisingly little is known about the psychobiology of this learning phenomenon in humans. Whereas animal work has frequently applied methods to examine generalization gradients to study the gradual weakening of the conditioned-fear response as the test stimulus increasingly differs from the conditioned stimulus (CS), to our knowledge no psychobiological studies of such gradients have been conducted in humans over the last 40 years. The current effort validates an updated generalization paradigm incorporating more recent methods for the objective measurement of anxiety (fear-potentiated startle). The paradigm employs 10, quasi-randomly presented, rings of gradually increasing size with extremes serving as CS+ and CS−. The eight rings of intermediary size serve as generalization stimuli (GSs) and create a continuum-of-similarity from CS+ to CS−. Both startle data and online self-report ratings demonstrate continuous decreases in generalization as the presented stimulus becomes less similar to the CS+. The current paradigm represents an updated and efficacious tool with which to study fear generalization—a central, yet understudied conditioning-correlate of pathologic anxiety.  相似文献

In this paper we examine a puzzle recently posed by Aaron Preston for the traditional realist assay of property (quality) instances. Consider Socrates (a red round spot) and red1—Socrates’ redness. For the traditional realist, both of these entities are concrete particulars. Further, both involve redness being `tied to’ the same bare individuator. But then it appears that red1 is duplicated in its ‘thicker’ particular (Socrates), so that it can’t be predicated of Socrates without redundancy. According to Preston, this suggests that a concrete particular and its property instances aren’t genuinely related. We argue that Preston’s proffered solution here—to treat property instances as “mental constructs”—is fraught with difficulty. We then go on to show how, by fine-tuning the nature of bare particulars, treating them as abstract modes of things rather than concrete particulars, the traditional realist can neatly evade Preston’s puzzle.

We examined the influence of prior exposure to specific animal properties on 15-month-old infants' inductive generalization. Using picture books, 29 infants were trained on properties linked in a congruent or incongruent manner with four animal categories. A generalized imitation task was then administered to assess patterns of property extension for two of the trained properties as well as two untrained properties aligned with the training categories. Prior exposure to particular category-property relations was shown to impact infants' property extensions in that infants selected a novel member of the training category for their imitation. For untrained properties, infants selected equally between novel members of the training and non-training categories. The findings highlight the dynamic nature of inductive processes in infancy.  相似文献

Considered a naturally occurring process common to older adults, the life review becomes a more productive process through facilitation and development and application of effective prompts. The experiences of 6 older adults who participated in a facilitated life review process and the manner in which individualized prompts were developed are described.  相似文献

Despite much recent work examining the short‐term effect of counselling in primary healthcare settings, to date relatively little research has examined the effectiveness of such treatment programmes over the longer term. In this study, 58 participants underwent brief, time‐limited integrative counselling sessions, with symptoms being measured using the CORE‐OM immediately before, immediately after, and 30 months after counselling. It was found that in addition to participants reporting significantly lower levels of psychological distress immediately post‐counselling, a further significant improvement at 30‐month follow‐up was also apparent, indicating that the benefit from counselling was maintained. In addition to this reduction in symptoms post‐counselling, a significant reduction in GP visits was also detected in the 12 months following counselling when compared with the 12 months prior to counselling, indicating a lower reliance on the primary healthcare team after counselling.  相似文献

Disordered eating is linked to body shapes and images presented in the mass media. Favored celebrities may represent a particularly strong source of influence. We examined cross-sectional relationships between women's disordered eating and their perceptions of body-shape differences with favored celebrities. Women between the ages of 18 and 27 rated personal body shapes alongside those of self-selected favored celebrities. Multivariate analyses showed self/celebrity body-shape discrepancies to be linked to EAT-26 diet, bulimia, and oral control scales independent of personal body-shape and self/ideal discrepancies. For bulimia subscale scores, this relationship was moderated by a more favorable perception of the celebrity relative to the self. Celebrities might be important in creating an unrealistic social comparison standard that contributes to disordered eating.  相似文献

We present data from the Center for Epidemiological Studies-Depression Scale (CES-D; Radloff, 1977) for 2 samples of Hong Kong community adolescents (combined N = 1,385). The 4 positive affect items related poorly to the remainder of the scale. Using 16 items, the data were consistent with 2 models with highly correlated factors: (a) a 2-factor model, 1 of which merged somatic and affective items, and (b) a 3-factor model separating somatic, depressed, and interpersonal items. Correlations with related constructs provide preliminary support of validity. Hong Kong adolescents are influenced both by traditional concepts of mind-body holism and Western psychological models separating psychological and somatic symptoms.  相似文献

The set of statistical methods available to developmentalists is continually being expanded, allowing for questions about change over time to be addressed in new, informative ways. Indeed, new developments in methods to model change over time create the possibility for new research questions to be posed. Latent transition analysis, a longitudinal extension of latent class analysis, is a method that can be used to model development in discrete latent variables, for example, stage processes, over 2 or more times. The current article illustrates this approach using a new SAS procedure, PROC LTA, to model change over time in adolescent and young adult dating and sexual risk behavior. Gender differences are examined, and substance use behaviors are included as predictors of initial status in dating and sexual risk behavior and transitions over time.  相似文献
