Individuals confronted with a life-threatening illness often report posttraumatic growth (PTG) or finding benefits in disease. These positive evaluations of personal strength, perceptions of improved personal relations and new possibilities may represent a defensive response (cf Janus-face model). Three studies investigated the effects of mortality reminders on reports of PTG or benefit findings among people living with life-threatening illness or their caregivers. 80 people living with HIV (Study 1), 164 breast cancer survivors (Study 2) and 50 family caregivers for a patient with Huntington Disease (Study 3) were randomly assigned to the experimental (mortality reminders) or control conditions. Across three studies, those exposed to mortality reminders reported lower PTG or benefit finding, compared to the controls. These effects were moderated by time elapsed since diagnosis: mortality reminders led to lower PTG/benefit finding among those who received the diagnosis more recently. The results provide an insight into the defensive character of PTG/finding benefits in illness and changes in the function of these beliefs over time elapsing since diagnosis. 相似文献

Different methods have been employed to assess handwriting posture in left-handers, and different dimensions of hand posture have been used for categorization. Within North American samples, there is a remarkable consistency between studies in the distributions when the same assessment method is used, but there are very large and highly significant differences for different methods of assessment. The various methods and dimensions of categorization evidently index different variables, and these are likely to have different relations with neuropsychological factors. It is possible, however, to gather questionnaire data on handwriting posture that closely resemble direct experimenter observation, as a brief report on left-handed males shows. 相似文献

Three case studies are presented to further our understanding of how responsibility is negotiated in families when making decisions about genetic risk. These draw on a model of responsibility generated in a study of reproductive decision-making in families facing Huntington disease (HD) to illustrate the impact of prenatal testing on this process. This involves analyzing: how people present themselves as acting responsibly whether or not they utilize genetic testing; who they feel responsible to in their family and elsewhere; the impact that testing has on these relationships; and, how negotiating responsibility changes over time with repeated use of prenatal testing, changing risk status and maturational changes. Two key findings are: how decision-making is perceived can become as important as what is decided; and, how responsibility is negotiated depends on which of these relationships are prioritized. Implications of the findings for clinical practice are noted and suggestions made for further applications of the model. 相似文献

The Vocational Preference Inventory and the Edwards Personal Preference Schedule were administered to 372 undergraduates. The two instruments were compared using canonical analysis. The analysis revealed three significant relationships between components of the two instruments. The relationships were viewed as supportive of Holland's theory of personality types. 相似文献

Three formal hypotheses are specified concerning the combination of neural signals from the two eyes. The hypotheses are (1) that a large uniform light presented to the opposite eye has no effect (independence), (2) that all information from one eye relevant to a given percept (for example, brightness) is encoded by a single neural signal (isolation), and (3) the mutually exclusive and exhaustive alternative to isolation (interaction). Though independence or isolation often has been claimed or simply assumed to hold, these hypotheses imply specific empirical relationships. These relationships are derived for brightness and for equilibrium colors. In addition, one model consistent with the interaction hypothesis is developed. The isolation hypothesis is important for generalizing results from monocular experiments to normal binocular vision. If it is false, monocular results can reflect a combination of one eye's neural signals that never occurs with binocular stimuli. 相似文献

To investigate the effects of distraction and attention-focusing during in-vivo exposure to feared stimuli, the responses of 16 obsessive-compulsives with washing rituals were studied. A cross-over design was employed in which 6 of the subjects underwent exposure with attention focusing on the first day followed by exposure with distraction on the second day. The remaining subjects received the reverse order. Habituation of both heart rate and subjective anxiety was observed under both conditions, the rate of habituation tending to remain constant throughout the 90-min exposure. Greater between-session habituation and greater synchrony between the psychophysiological and the subjective measures of anxiety was observed when attention-focusing preceded distraction. Since habituation and synchrony have previously been found to be positively related to treatment outcome, the present results suggest that treatment by exposure to feared stimuli may be more effective if attention-focusing is promoted. 相似文献
