In three experiments experience with shock was shown to reduce the effectiveness of shock as a reinforcer or motivator. In Experiment 1 rats were given signaled shock in a box separate from the runway where they were subsequently punished. These rats were less suppressed by shock punishment than rats that had no previous shock experience. In Experiment 2 preshocked rats were less suppressed by punishment and were slower to learn an escape-avoidance response than nonpreshocked rats, whether the preshock was signaled or unsignaled. In Experiment 3 as number of CS-shock pairings increased, fear of the CS decreased as did fear of the context. These results suggest that some central adaptation process produced by experience with shock reduces the effectiveness of shock as a reinforcer whenever shock is used repeatedly. This is independent of other effects, such as context blocking, that can affect responding after shock preexposure. 相似文献

THE CULTURAL CONTEXT: A FACTOR IN ASSERTIVENESS TRAINING WITH MAINLAND PUERTO RICAN WOMEN 总被引:1,自引:0,他引:1
This study examined the inclusion of a cultural component in an assertiveness training program. Participants ( n = 40) were low income Puerto Rican women. There were four training groups divided up according to educational level. In addition, there was a no-training group consisting of Puerto Rican women who did not receive assertiveness training. Ten sessions of an hour and a half each were conducted over a period of 10 weeks. The training program was evaluated using a translation of the Adult Self-Expression Scale (Gay, Hollandsworth, & Galassi, 1975) as a pre/post program measure of assertiveness; evaluation forms completed by recipients at the close of each session were also used for evaluation purposes. Assertiveness scores of the training group were significantly higher than those of the no-training group. In addition, this effect was true regardless of level of education. Session-by-session evaluation forms suggested that cultural context may be an important mediator of assertive behavior. Limitations of the study are discussed, and it is recommended that future research examine the role of cultural factors in assertiveness training. 相似文献

Home observations of mother-father-infant interaction and mother-infant interaction were contrasted in middle-class families in which the mother was employed or a full-time caregiver. First-born infants and their parents were observed at 3 months. The results indicate that when mother, father, and infant were together parents in the single wage-earner families provided more tactile stimulation to their babies; fathers in single wage-earner families tended to interact more with their infants than did mothers, while in dual wage-earner families mothers tended to interact more than fathers; and fathers in single wage-earner families exceeded fathers in dual wage-earner families in interactions with their infants. By contrast, mothers in the two groups showed very little difference in their interactions with their babies. No significant differences were found for maternal behavior in the three-person observation, and a single behavior differentiated between the groups in the mother-baby observation, with homemaker mothers more often making visual contact with their babies. The implications of these findings are discussed, both with respect to further research, and with regards to the development of children of employed mothers. 相似文献

Child and adolescent survivors of parental suicide experience two stressful events simultaneously: (1) the loss of a primary caregiver, and (2) suicidal death of a significant person. These youths are thought to be at increased risk for mental health problems, but a systematic review of studies on these survivors has not yet been conducted. A comprehensive search for published literature identified nine studies. The existent studies provided modest yet inconsistent evidence on the impact of parental suicide on offspring psychiatric and psychosocial outcomes. More methodologically rigorous research is needed to inform and guide postvention efforts for these survivors. 相似文献

Taiwan has one of the highest suicide rates in the world, especially among its elderly. The epidemiologic characteristics and trends of the surging elderly suicide rates from 1993 to 2003 are described, with a special emphasis on the risk groups, the methods used in suicide, and their geographical variations. Data on annual mortality for persons over 65 years of age with external cause‐of‐death codes E950–E959 were obtained from the Death Certification data file provided by the Department of Health and used in the analysis. The suicide rate for each 5‐year age group over 65 years old increased during the 11‐year period. Elderly males had the highest suicide rate and experienced an increased rate of 49% during the decade. The average suicide ratio between elderly males and females was about 2:1. Never‐married males had the highest age‐adjusted as well as sex‐ and marital status‐specific suicide rates, and showed an increased rate of 66% over the 11‐year period. Geographical variations in suicide rates were significant, with the lest urbanized eastern Taiwan having a higher rate than other regions. Hanging, strangulation, and suffocation were the most used methods for committing suicide by the elderly, but their use had decreased from 63% to 54% during the decade; but jumping off a building and drowning increased significantly. Variation in suicide rate among months was not significant. With the increase in the elderly suicide rate, more governmental and societal interventions are needed to alleviate this social and human problem. 相似文献

The rates and associated features of suicidal ideation among 5,641 patients seeking routine, nonsuicide related care in an inner‐city emergency department were examined. Approximately 8% of patients seeking routine care in the emergency department reported some form of suicidal ideation within the past 2 weeks. Suicidal ideation was common in individuals who were single with poorer mental health, had higher depression, and had received some drug or alcohol treatment in the past 3 months or had used cocaine or marijuana in the past 30 days. Improved screening procedures could help to identify routine care patients who are at risk for suicide. 相似文献

Chain of care for patients with intentional self‐harm was important in the Norwegian national action plan to prevent suicide. In this study there were two aims: (1) to calculate the potential effects of chain of care on reducing suicide rates, and (2) to assess whether suicide rates decreased more in areas where chain of care had been implemented than in other areas. We observed no differences in changes in suicide rates between areas with and without the intervention. The calculated potential effects of chain of care on national suicide rates were very small, even under unrealistically favorable conditions. 相似文献

Rumination has been persistently implicated in the etiology of hopelessness and depression, which are proximal predictors of suicidality. As a result, researchers have started to examine the role of rumination in suicidality. This systematic review provides a concise synopsis of the current progress in examining the relationship between rumination and suicidality, and highlights areas for future research. A search of the international literature was conducted using the three main psychological and medical databases. Eleven studies were identified providing evidence, with one exception, of a relationship between rumination and suicidality. This review also highlights the considerable dearth of studies on this area of concern, specifically of case‐control and prospective, clinical studies, in the worldwide literature. 相似文献
