Objective: This study explores cardiovascular reactivity during an acute-stress task in a sample of recently separated adults.

Design: In a cross-sectional design, we examined the association between adults’ subjective separation-related distress and changes in heart rate and blood pressure across the acute-stress laboratory paradigm in a sample of 133 (n = 49 men) recently separated adults.

Main outcome measures: Heart rate (HR) and Blood pressure (BP) were recorded across a resting baseline period, a math stressor task, and a recovery period.

Results: Multilevel analyses revealed that adults who reported greater separation-related distress exhibited higher initial BP and a slower linear increase in BP across the study period. In addition, adults reporting greater separation-related distress evidenced significantly slower declines in diastolic blood pressure (DBP) following the acute-stress task. HR reactivity was not moderated by separation-related distress.

Conclusions: In recently separated adults, preliminary evidence suggests that the context of the stressors may reveal differential patterns of problematic reactivity (exaggerated or blunted responding). Greater emotional intrusion and hyperactivity symptoms may index increased risk for blunted cardiovascular reactivity to general stressors. This pattern of reactivity is consistent with models of allostatic load that emphasise the deleterious effect of hyporesponsivity to environmental demands.  相似文献

Abstract :  Much of Jung's later work assumes that the self is an  a priori  phenomenon in which centripetal dynamics dominate. There is, however, another current in Jung's writings which recognizes the self to be an emergent phenomenon. This view is increasingly prevalent in post-Jungian discourse, and Louis Zinkin's exploration of a post-Jungian-constructivist model of the self can be seen as part of this tendency.
My paper privileges an emergent understanding of the self by focusing on the 'unravelling', 'de-centring', centrifugal experiences of otherness in the psyche. It offers a post-Jungian reading of a number of writers who have been influenced by the psychoanalyst Jean Laplanche and proposes a model of the self which focuses on our fantasies, terrors and longings about coming undone and bringing others undone.
This model is then linked to Judith Butler's understanding of the self as an ec-static phenomenon, in which the self is, of necessity, outside itself, such that 'there is no final moment in which my return to myself takes place'. I suggest that Jung's early clinical researches into the dissociability of the psyche and the clinical tools which he developed as a result of this work are especially suitable for engaging with these emergent, centrifugal dynamics.  相似文献

In this investigation of adults' solution strategies for simple arithmetic, participants solved addition problems (e.g., 2 + 3, 8 + 7) under fast and slow response deadlines: The participants were instructed either to respond before a 750-msec warning beep, or to wait for a 2,500-msec beep before responding. After each trial, they indicated whether they had solved the problem by direct memory retrieval or by using a procedural strategy (e.g., counting, transformation). It was predicted that the fast deadline condition should curtail the use of procedural strategies, which generally are slower than direct retrieval. Furthermore, this deadline effect should be exaggerated for numerically larger problems because procedural strategies are especially slow for the larger problems. As predicted, we observed a deadline x size interaction whereby the fast deadline increased reported use of retrieval, especially for large problems. The results confirm that reported use of direct retrieval decreases systematically with elapsed time, and they provide additional evidence that young, educated adults rely substantially on procedural strategies even for simple addition.  相似文献

A seatbelt-gearshift delay was evaluated in two U.S. and three Canadian vehicles using a reversal design. The seatbelt-gearshift delay required unbelted drivers either to buckle their seatbelts or to wait a specified time before they could put the vehicle in gear. After collecting behavioral prebaseline data, a data logger was installed in all five vehicles to collect automated data on seatbelt use. Next the seatbelt-gearshift delay was introduced. The results showed that the delay increased all 5 drivers' seatbelt use, and that the duration of the delay that produced relatively consistent seatbelt use varied across drivers from 5 to 20 s. When the device was deactivated in four of the five vehicles, behavior returned to baseline levels.  相似文献

A two-part systematic review was undertaken to assess the effectiveness of token economies in increasing rates of appropriate classroom behavior for students demonstrating behavioral difficulties. The first part of the review utilized the recently published What Works Clearinghouse (WWC) standards for evaluating single-subject research to determine the extent to which eligible studies demonstrated sufficient evidence to classify the token economy as an evidence-based practice. The second part of the review employed meta-analytic techniques across four different types of effect sizes to evaluate the quantitative strength of the findings. Methodological strengths and weaknesses across the studies were systematically investigated. Results indicated that the extant research on token economies does not provide sufficient evidence to be deemed best-practice based on the WWC criteria.  相似文献
