This investigation adopted a multiple case study approach to determine the personality functioning in people living with HIV/ AIDS (PLWHA). Participants comprised a convenience sample of four PLWHA (male?=?3, female?=?1). The majority of the participants were white (n?=?3) and one was black African. Only one participant was married at the time of participation. Data on aspects such as their suicidal ideation, affect, problem solving styles, ego functioning, self-perception, and interpersonal functioning were collected using the Rorschach inkblot test and clinical interview. The data were actuarially analysed and organised under themes, namely; dominant personality style, capacity for control and stress, situational related stress, affect, interpersonal relations and self-perception. Findings revealed that participants had high levels of potential mood disorders and interpersonal difficulties for which targeted psychological services may be needed.  相似文献

This study investigated children's experiences and understandings of the HIV/AIDS pandemic. Grade 3 children (n=31) from the province of KwaZulu-Natal aged between 8–11 years were participants in the study. Data were collected through a four-stage focus group process including activities such as diagrammatic mapping, drawing, timelines, projective techniques and ranking exercises. The findings suggest that the meanings children make about HIV and AIDS are contextual and situational. Moreover, the contexts in which children live act as power sites where struggles over meaning and meaning making occur.  相似文献

This study explored some of the complexities through which young adults construct and represent their sexual identities within the context of HIV/AIDS. The sample comprised a total of 136 (female = 77; male = 59) Indian and African learners, who were between the ages 15–19 years, in a co-educational school in the province of KwaZulu-Natal. The main methods of data collection employed were questionnaires and semi-structured interviews. The findings revealed that most young people understand their teenage years as transitional, hormonal and necessarily experimental, and particularly with regard to sexual experimentation. The dominance of heterosexual morality and the transitional status of the adolescents appeared to erode young adults' power to act as responsible agents.  相似文献

The present study adopted procedures similar to those used by Logan (1965) to determine choice behavior in children. The objective was to provide an improved methodology in delay-of-gratification studies, thus avoiding the problems associated with scaling different kinds of rewards, and to provide approximate functions relating a delay-of-token reward to choice behavior. Thus, 7 girls aged 8 to 10 years were exposed to a choice paradigm in which a larger reward (2 tokens) was pitted against a smaller reward (1 token); access to these rewards was delayed a certain period of time. The results of this experiment showed that as the delay of the larger reward increased, preference for the smaller reward increased in an orderly fashion. The finding that delay shifted preference from the larger to the smaller reward is discussed in relation to current theory. The results of this experiment also provide evidence for the utility of tokens in scaling incentives for choice studies.  相似文献

The present study extends the feedback-seeking behavior literature by investigating how supervisor-related antecedents (i.e., supervisors’ expert power, reflected appraisals of supervisors, and supervisors’ emotional intelligence) influence subordinates’ negative feedback-seeking behavior (NFSB) through different cost/value perceptions (i.e., expectancy value, self-presentation cost, and ego cost). Using data collected from 216 supervisor-subordinate dyads from various industries in Taiwan, we employ structural equation modeling analysis to test our hypotheses. The results show that expectancy value mediates the relationship between supervisor expert power and subordinates’ NFSB. Moreover, self-presentation cost mediates the relationship between reflected appraisals of supervisors’ and subordinates’ NFSB. Theoretical and practical implications of this study are also discussed.  相似文献

ABSTRACT. Research suggests that children may interfere with single parents’ romantic experiences. Although both male and female single parents face these challenges, they have stronger associations with the romantic satisfaction of single mothers as compared to single fathers. The two current studies examined aspects of attractiveness and dating across various dimensions for both younger single women and men, with and without children. Results of Study 1 indicated interactive effects of target gender and parental status on perceptions of both attractiveness and dating potential. Results of Study 2 indicated differential ratings on multiple dimensions (i.e., attractiveness, stress, motivation for dating, and positive qualities) of younger single adults on the basis of gender, parental status, and the number of children single parents were reported as having. Implications for importance of social support and difficulty of repartnering are discussed.  相似文献

The goal of the present study was to test the Perceptual-Attentional Limitation Hypothesis in children and adults by manipulating the distinctiveness between expressions and recording eye movements. Children 3–5 and 9–11 years old as well as adults were presented pairs of expressions and required to identify a target emotion. Children 3–5 years old were less accurate than those 9–11 years old and adults. All children viewed pictures longer than adults but did not spend more time attending to the relevant cues. For all participants, accuracy for the recognition of fear was lower than for surprise when the distinctive cue was in the brow only. They also took longer and spent more time in both the mouth and brow zones than when a cue was in the mouth or both areas. Adults and children 9–11 years old made more comparisons between the expressions when fear comprised a single distinctive cue in the brow than when the distinctive cue was in the mouth only or when both cues were present. Children 3–5 years old made more comparisons for brow only than both. The results of the present study extend on the Perceptual-Attentional Limitation Hypothesis showing an importance of both decoder and stimuli, and an interaction between decoder and stimuli characteristics.  相似文献
