This exploratory study uses qualitative methods to focus on the largely unexamined role of the grandfather and to examine men's experiences as grandfathers. We gathered information through both surveys and individual interviews to explore men's feelings and attitudes toward the grandfather role. Of the 51 grandfathers that completed a survey, 20 participated in interviews. Our examination of the data collected reveals the life lessons men teach their grandchildren. The grandfathers in this study expressed strong desires for purposeful involvement in their grandchildren's lives and indicated desires for transferring values to grandchildren and teaching interpersonal relationships. Through this involvement, they educate through life experiences and serve as mentors for their grandchildren. We suggest that this mentoring role makes a positive contribution to the lives of grandchildren and to the identity of grandfathers.  相似文献

A modified version of Caplan's Job Stress Questionnaire (JSQ) was administered to 169 male and 56 female entrepreneurs. Entrepreneurs were found to have higher levels of stress associated with workload than with role ambiguity and underutilization of skills. Compared to scores reported previously for various occupational categories, the entrepreneurs scored significantly higher than did white collar, blue collar, and professional groups on the workload scale and significantly lower on scales measuring role ambiguity and under-utilization of skills. These results may be due to the nature of entrepreneurial activity, which is often characterized by heavy workloads, long hours, and a self-established role in the organization. Additionally, the factorial composition of the JSQ and its internal consistency were examined. Evidence of convergent and discriminant validity at the item and subscale level confirmed the a priori dimensions of the JSQ, although the internal consistency of the scales were low to moderate. The need for various improvements in the measurement of occupational stress is briefly discussed.  相似文献

Maternal and adolescent depression are challenges that often co-occur. Many studies have drawn bivariate associations between maternal depressive symptoms, adolescent depressive symptoms, and family conflict, but few have examined reciprocal effects. Even among extant studies, there is a lack of clarity related to directionality of influence. Three competing theoretical models may explain the relationship between maternal depressive symptoms, adolescent depressive symptoms, and family conflict, and these processes may differ by adolescents’ sex. Using three time points of data from 187 diverse mother-adolescent dyads, we fit a taxonomy of autoregressive cross-lagged structural equation models to simultaneously evaluate the competing theoretical models and also examine differences by sex using multiple-group analyses. Results indicate a symptom-driven model whereby adolescent depressive symptoms predicted increases in family conflict. Sex differences were also found. For males, but not females, greater adolescent depressive symptoms predicted subsequent increases in maternal depressive symptoms, which then predicted lower family conflict—possibly indicating maternal disengagement/withdrawal. Our findings suggest addressing adolescent depressive symptoms in order to prevent family conflict and that distinctive targets for the prevention/intervention of family conflict should account for differences by adolescents’ sex.  相似文献

The aim of this study was to investigate whether the phonological code that causes errors in printed sentence comprehension is affected by concurrent articulation. Forty adult subjects made speeded judgements of the acceptability of printed sentences. The critical sentences were foils that were (1) orthographi-cally unacceptable but phonologically acceptable (e.g. The palace had a thrown room), and (2) spelling controls that were orthographically and phonologically unacceptable (The palace had a thorns room). Half the subjects performed this task in silence (without concurrently articulating) and showed a marked phonological effect such that false alarms to phonologically acceptable foils were more frequent than false alarms to their spelling controls. The remaining subjects who performed this task with concurrent articulatory suppression showed an increase in false alarm rates, but no effect of phonology. In a control experiment using the same subjects, memory span for visually presented long and short words was measured under conditions of silence or concurrent articulation. The word length effect (Baddeley, Thomson, & Buchanan, 1975) disappeared under suppression, indicating that the suppression manipulation was highly effective. Thus the phonological codes that are used both in sentence comprehension and memory span are highly susceptible to articulatory suppression. We discuss possible relationships between phonological codes that mediate lexical access and those that support short-term verbal memory.  相似文献

Prior studies have indicated that post-encoding stress can protect memories from the effects of forgetting, and this has been taken as evidence that stress facilitates memory consolidation. However, it is not known whether stress acts by directly influencing the strength of the underlying memories or whether it influences the generation process that plays a critical role in tests such as free recall. To address this issue, we examined the effects of stress produced by skydiving on recognition memory for negative and neutral pictures. Relative to a non-stress control condition, post-encoding stress in males was found to increase recognition memory for neutral pictures. However, stress was not found to improve recognition for emotional pictures, nor was it found to influence recognition memory in female participants. Additional analysis of recognition performance suggested that stress increased familiarity-based recognition rather than recollection. This study indicates that stress can improve familiarity-based recognition, thus showing that stress directly increases the strength of the underlying memories.  相似文献

InMetaphysics , Ch. 4, Aristotle speaks of both infinite regress and question-begging, but does not explicitly relate them. We get the impression that he thinks that to use one of these arguments to avoid the other is to jump from the frying-pan into the fire. This relationship is illustrated in terms of the ignorant belief that everything can be proved, and of attempts to prove the Law of Noncontradiction.  相似文献

Evidence from experimental psychology provides unequivocal support for enhanced creativity among individuals who are prone to psychotic and mood disorders. At the same time, there is strong epidemiological evidence for greater incidence of creative achievement among those diagnosed with bipolar disorder (but not schizophrenia). This review examines the evidence for common factors predisposing an individual to creativity and psychosis, as well as factors that distinguish the capacity for creative achievement from the creative potential that may be inherent in psychosis vulnerability. Factors implicated as common to creative potential and psychosis vulnerability include enhanced divergent thinking, reduced latent inhibition and preattentive filtering mechanisms; on the other hand, greater cognitive flexibility, motivation, and openness to experience tend to be associated with creative achievement, but not psychosis. This evidence is considered with respect to the utility of tailored vocational interventions to effectively harness creative potential, which may be useful for young individuals in the early stages of illness or their unaffected family members.  相似文献

It is generally accepted that the anterior temporal lobes support knowledge of famous people. The specific roles of the right and left temporal lobe remain a subject of debate, with some studies suggesting differential roles based on modality (visual versus verbal information) and others category (person knowledge versus general semantics). The present study re-examined performance of semantic dementia patients with predominantly right and predominantly left temporal lobe atrophy on famous face, famous name and general semantic tasks, with the specific aim of testing the hypothesis that the right temporal lobe has a privileged role for person knowledge and the left temporal lobe for general semantic knowledge. Comparisons of performance rankings across tasks showed no evidence to support this hypothesis. By contrast, there was robust evidence from naming, identification and familiarity measures for modality effects: right-sided atrophy being associated with relatively greater impairment for faces and visual tasks and left-sided atrophy for names and verbal tasks. A double dissociation in test scores in two patients reinforced these findings. The data present a challenge for the influential `semantic hub' model, which views the anterior temporal lobes as an area of convergence in which semantic information is represented in amodal form.  相似文献

National surveillance data indicate marked differences between Indigenous and other Australians in the prevalence of many sexually transmitted infections (STIs). Young Indigenous people bear a particularly high burden of these infections. A collaboration of university researchers, Indigenous health workers and young Indigenous people conducted 45 field interviews to examine how young Indigenous Australians keep themselves healthy and protected against STIs. Our findings emphasise the complexity of health behaviours, where individuals are rarely always ‘risky’ or always ‘safe’, as well as subtle gender differences in health practices. Preventive strategies employed by the young people were contingent on beliefs and knowledge about sexual partners, the type of relationship, the context of the sexual encounter and access to condoms. Tangible strengths such as young Indigenous people's commitments to condoms and STI screening should be celebrated and bolstered to enhance their ability to protect themselves against adverse health outcomes and enhance their resilience against STIs. Focusing on strengths helps to counter the deficit model of health commonly deployed in Indigenous health research and draws attention to health issues facing young Indigenous people and their communities, without reinforcing negative stereotypes or focusing solely on individual risk behaviour. We provide concrete recommendations for health promotion and education. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献
