Imagining alternatives to actual experiences is an important part of everyday life that can take many forms. One manifestation in middle childhood is the creation of elaborate imaginary worlds, called paracosms. Retrospective reports of adults indicate that having a childhood paracosm is more commonly reported in individuals acknowledged for being highly creative. In this study, we interviewed four children aged 10 to 12 years with interconnected paracosms about the details of their imagined worlds. Our findings indicated that paracosms served as a platform for social activity with friends, a way to explore real world interests (e.g., geography, language), and a vehicle for engaging in creative pursuits (e.g., drawing, storytelling).  相似文献

Developmental changes in the kinematics and kinetics underlying balance control were studied in 61 children, 9 months to 10 years of age. The children were classified according to developmental milestones as standers; new, intermediate, and advanced walkers; runners-jumpers; hoppers; gallopers; and skippers. The children experienced support-surface translations of varying size and speed. Children with greater locomotor experience withstood larger balance threats without collapsing or stepping. Analyses of scaled trials (perturbations normalized in size to foot length and center of gravity height) revealed that improvement in balance was not related to initial configuration parameters surrounding the task (degree of crouch or lean). Children with advanced locomotor skills had faster recovery times and relatively larger muscle torques than children with less experience. Relative torque-time histories of the more experienced children began to match the adult response to similar perturbations. With increased experience and changing muscle torque regulatory abilities, balance skills became more robust.  相似文献

The sales job of the early twenty-first century has evolved due to myriad rapidly changing environmental factors. Customer relationship focus, technology, global competition, shifting customer preferences and demands, forced downsizing, increased competitive pressure, and other factors have contributed to altering the salesperson role—what salespeople do. Yet outdated taxonomies are referenced when researching and writing about sales jobs. This paper develops an empirically generated sales position taxonomy based on changing selling activities and strategies. First, a set of 105 activities are factor analyzed to create 12 dimensions of selling. Second, the factor scores are entered into a cluster analysis. The resulting factor score centroids allow for interpretation of a taxonomy of six categories of contemporary sales jobs.  相似文献

This presentation aims at demonstrating the emergence of a basic disturbance in the analytic material of anorexic and bulimic patients, namely, the unconscious attempt to restore the lost union with the feeding mother which is both relentlessly sought and equally feared. Food is used unconsciously to represent and control intra-psychically both the object and the affects belonging to that relationship in such a way as to avoid terror of fusion or dissolution of the self.  相似文献

The present studies tested the hypothesis that strong assumptions about within-category homogeneity impede children's recognition of the inductive value of diverse samples of evidence. In Study 1a, children (7-year-olds) and adults were randomly assigned to receive a prime emphasizing within-category variability, a prime emphasizing within-category similarities, or to not receive a prime. Only following the variability prime, children demonstrated a reliable preference for evaluating diverse over nondiverse samples to determine whether there is support for a category-wide generalization. Adults demonstrated a robust preference for diverse samples in all conditions. These effects extended beyond the specific categories included in the prime, as well as to multiple types of test questions. Study 1b demonstrated that priming variability leads children to select diverse samples only when doing so is informative for induction. Implications for conceptual development are discussed.  相似文献

Abstract

This study investigated the reactions of Canadian unionized production workers following a plant closing announcement. Workers who had been transferred reported significantly greater job security, more trust in the company, greater commitment to the company, and higher job performance than workers who remained at the plant. They also reported less trust in their union than the remaining workers. Perceived supervisor support was positively related to company trust and company commitment and perceived union support was positively associated with union trust and union commitment. High stress appraisal (perceived injustice and job insecurity) was associated with increased strain, lower job performance, reduced trust in the company, and reduced company commitment, but had no significant effect on the union-related outcomes. The implications of these findings for companies and unions are discussed.  相似文献

Students in a general psychology class viewed four videotapes of initial vocational-educational and initial personal concern counseling sessions. The sessions were presented from a client-centered approach and from a behavioral approach, and employed the same client and counselor. After viewing the tapes, the students were asked to indicate which approach they thought would be more effective in helping a client. Results showed that students who had previously experienced counseling preferred a behavioral approach for both the vocational-educational concern and the personal concern. Students with no experience of counseling did not exhibit a preference.  相似文献

This study of Israeli and American preadolescent children examined characteristics of friendship in 44 children with high-functioning autism spectrum disorder (HFASD) compared to 38 typically developing children (TYP), as they interacted with a close friend Participants were 8-12 years of age (HFASD: Israel, n = 24; USA, n = 20; TYP: Israel, n = 23; USA, n = 15), and were matched on SES, receptive language vocabulary, child age, and gender (each study group included one girl). Multidimensional assessments included: individual behaviors of target children and observed child-friend interactions during construction and drawing scenarios; target child's and friend's self-perceived mutual friendship qualities; and mother-reported characteristics (friendship's duration/frequency; friend's age/gender/disability status). Overall, children with HFASD displayed a number of differences on individual and dyadic friendship measures. Both age and verbal abilities affected friendship behaviors. Children with HFASD and their friends perceived friendship qualities similarly, suggesting that preadolescents with HFASD have capacities for interpersonal awareness. Between-group similarities also emerged on several complex social behaviors, suggesting that friendship follows a developmental trajectory in autism and may enhance social interaction skills in autism.  相似文献

The association between specific types of peer victimization with depression, suicidal ideation, and suicide attempts among adolescents was examined. A self-report survey was completed by 2,342 high-school students. Regression analyses indicated that frequent exposure to all types of peer victimization was related to high risk of depression, ideation, and attempts compared to students not victimized. Infrequent victimization was also related to increased risk, particularly among females. The more types of victimization the higher the risk for depression and suicidality among both genders. Specific types of peer victimization are a potential risk factor for adolescent depression and suicidality. It is important to assess depression and suicidality among victimized students in order to develop appropriate intervention methods.  相似文献
