A technique is described that permits precise synchronization of video recorded behavior with discrete stimuli and responses. These discrete events are recorded as digital data on the video channel of a video recorder on a horizontal line that lies above the visible video information. These data may be observed in single-frame playback mode by underscanning the playback monitor. A circuit is described for computerized decoding of the digital data. Because each video field is uniquely coded, an updating of the data is possible 60 times each second. The described technique has several advantages over current approaches for synchronizing discrete stimulus and response events with video recorded behavior. 相似文献

The death of a child, is perhaps one of the most excruciating events that a family could experience. Although much literature exists on the short-term effects of child death, little is written on the long-term family repercussions.This article briefly reviews the literature on bereavement, and then focuses on the effects of child death in the family. Issues of specific interest to the family therapist are highlighted. 相似文献

Families frequently act as substitute decisionmakers for their older members who suffer from diminished mental capacity to make and express their own medical choices. Substitute decisionmaking takes on particular ethical and legal urgency within the nursing home environment, especially when choices concern potential medical treatment near the end of the nursing home resident's life. This article examines current legal mechanisms in the United States that enable a family to make substitute medical decisions, the ethical underpinnings of those mechanisms, and specific ethical and legal considerations implicated by their application to the nursing home setting. The article offers advice to nursing home professionals, including physicians, in working with families as substitute decisionmakers. 相似文献

Psychosocial Predictors of Change in Cigarette Smoking 总被引:1,自引:0,他引:1
John P. Kirscht Nancy K. Janz Marshall H. Becker 《Journal of applied social psychology》1989,19(4):298-308
Over a period of 6 months, factors related to change in cigarette smoking were investigated in a group of 250 adult outpatients, all of whom smoked at the time of enrollment in the study. Among the variables tested were demographic, social, and situational factors, beliefs about the health effects of smoking and difficulty of quitting, and intentions regarding future smoking. Information was gathered at baseline and the first and sixth months by means of telephone interviews. Relative to smoking at 6 months, intention, education, and professional advice made independent contributions to cessation. The processes of quitting were examined in more detail. Attempting to quit was related to intention, professional advice, level of smoking, and social cues to smoke. Among those who tried to stop, difficulty with urges to smoke, and education affected success versus failure. Earlier success related to less anxiety and tension, and to less difficulty in not smoking when in negative situations. The findings suggest that a complex set of social and cognitive factors affect change in smoking behavior, and that somewhat different factors are operative at different stages. 相似文献

Two career orientation factors, Career Centeredness and Career Commitment, were predicted to relate differentially to women's achievement motivation and sex-role identity. Career Centeredness is an orientation which places a career above other life activities (e.g., recreation, family life, etc.) as a source of satisfaction whereas Career Commitment concerns the intention of steadily pursuing a career throughout life. The expectation that Career Centeredness would be more characteristic of masculine women and correlate higher with achievement motivation than would Career Commitment was generally supported. Results are discussed in terms of societal support for these two career orientations and of role conflict experienced by women with different sex-role identities. 相似文献

Neostriatal dopamine and sensory inattention 总被引:3,自引:0,他引:3

Damage to the mesotelencephalic dopamine-containing projection of rats results in a sensory inattention, characterized by impairments in orientation toward somatosensory, visual, and olfactory stimuli. The present experiments were performed to establish which branch of this dopaminergic system is responsible for these sensorimotor deficits. Two approaches were used. In the first, individual dopamine-innervated forebrain sites were damaged by localized 6-hydroxydopamine injection into, or by electrolytic lesions of, these regions. In the second, rats were given tegmental 6-hydroxydopamine injections that damaged the entire mesotelencephalic projection and subsequently received intracerebral injections of the dopamine agonist apomorphine into specific forebrain sites in an attempt to reinstate orientation. The results demonstrate that dopaminergic terminals in the neostriatum are critical for orientation. Unilateral neostriatal 6-hydroxydopamine injections or electrolytic lesions reduced orientation to contralateral touch, whereas similar damage to other dopamine-innervated forebrain structures did not. Further, the results suggest that dopaminergic terminals in the anterior neostriatum are especially important for orientation to touch of the rostral body surface while those in the posterior neostriatum are most critical for orientation to caudal touch. After damage to all branches of the mesotelencephalic dopaminergic system, orientation to touch was reinstated by injection of apomorphine into the neostriatum but not by injection into the other dopamine-innervated forebrain regions tested. 相似文献
