The objective of this study was to assess, via heart rate, the arousal levels of participants in group trauma reexposure therapy
for posttraumatic stress disorder, and so to better understand this common mode of treatment, particularly in regards to its
presumed curative factor, extinction. Six Vietnam combat-related PTSD inpatients participated twice weekly in group trauma
reexposure therapy during which their electrocardiograms were recorded. Heart rate was quantified continuously off-line. Heart
rates of participantsnot directly engaged in imaginal reexposure to their personal combat traumas consistently exhibited mild linear declines from
the beginnings to the ends of the approximately 2.5 hour sessions. Participants actively engaged in personal combat trauma
reexposure exhibited higher whole-session heart rates. Most also exhibited more specific elevation extending over the later
portions of therapy sessions during which intensive reexposure usually occurred. Surprisingly, no patients exhibitedfocal increases in heart rate concurrent with periods of most intensive traumatic incident review as judged from videotape. Administering
imaginal reexposure in a group context does not preclude substantial physiological (sympathetic) arousal, as is preconditional
for extinction. Under conditions in which the actively engaged reexposure patient is reliably identified, group trauma reexposure
therapy may not provide an opportunity for “vicarious” flooding in nonengaged participants. 相似文献
Knowledge of basic arithmetic facts aids in the acquisition and speed of performance of arithmetic operations. A peer mediated instructional procedure, Classwide Peer Tutoring (CWPT), has been shown to increase the rates and accuracy of students responses to academic tasks and to improve student performance on a variety of academic tasks. The present investigation evaluated the retention of 100 subtraction items by primary grade-age children with mild disabilities using CWPT for 10 weeks. Short- and long-term retention of items, and rate of correct responding were assessed. Results indicated that the students' average pretest score was 58.0% correct, and their average weekly posttest score was 87.12 correct, a 27% improvement in accuracy. Short- and longer-term retention measured on posttests was 88.7 % and 85.0% correct, respectively. Improvement in students rate of accurate responding to subtraction items practiced during CWPT was obtained. Student failure to learn particular items was not attributable to fewer opportunities to practice these items, less accurate practice, or item difficulty. Students reported positive evaluation of CWPT and perceived positive social and self esteem outcomes. Directions for future research focusing on retention and analysis of treatment failure are suggested. 相似文献
Use of the Cognitive Failures Questionnaire (CFQ) in clinical research assumes that the questionnaire measures a single factor. A factor analysis of the CFQ was performed, on a sample of 475 students, using accurate procedures for determining the number of factors. These procedures gave mutually inconsistent results: at least two alternative factor structures can be extracted from the CFQ. An interpretable seven factor solution was found, but the CFQ probably has insufficient items to measure more than two strongly defined factors. The capacity of CFQ multiple factors to predict measures related to stress vulnerability was tested in a further study (N=57). Correlations between CFQ total score and neuroticism and use of coping strategies appeared to depend mainly on a single CFQ multiple factor, related to failures of concentration. Some of the other CFQ factors predicted other criteria. Further research on multiple factors of cognitive failure might improve the validity of the CFQ as a predictor of stress vulnerability and of cognitive performance. 相似文献
Eighteen 15-week-old, normal full-term infants were presented with photographic slides of a human facial expression. The infant's heart rate, body movement, and visual attention were recorded simultaneously. The results showed that heart rate and body movement were significantly correlated during visual attention but not during inattention. Both heart rate and body movement decelerated significantly when the infants visually attended to the target stimulus. The results are discussed with reference to cardiac-somatic integration in early infancy and its implication as a possible index of attention. 相似文献
This contribution is a commentary to a special issue titled “Example-based learning: New theoretical perspectives and advances to a contemporary instructional approach” published in Applied Cognitive Psychology (2020). In the commentary, the presented research is discussed with respect to three extensions compared with previous research, namely, theoretical frameworks, learning scenarios and domains. It concludes with some suggestions for methodological advancements. 相似文献
Freud introduced the concept of psychical reality as a consequence of abandoning the theory of seduction, and although this meant a turning point in his theoretical thinking he never defined the concept concisely and systematically. Thus it is possible to delineate at least two meanings of psychical reality that run through Freud´s writings as well as the writings of contemporary analysts. On the one hand psychical reality encompasses the whole field of subjective experiences. On the other, it is understood more narrowly as a transformation of experiences in the unconscious.
Substituting the idea of different meanings ascribed to Freud´s concept this article proposes to differentiate between levels in the psyche with the main focus on the unconscious level of the dream and of phantasy and the real unconscious. Starting from the most superficial level of subjective reality the text moves to that of fantasy formation illustrated by primarily Freud´s text on `A child is being beaten´. Adding Laplanche´s translational model the article ends up at the deepest level represented by the late Lacan and his concept of the real Unconscious.
The paper concludes that the term real points to something exceeding symbolization and the imaginary—thus escaping comprehension—and yet is absolutely indispensable to the organization of unconscious processes. 相似文献
Studies using a triaxial accelerometer and heart rate (HR) simultaneously for estimating energy expenditure (EE) during uphill exercise are rare. Exploring the optimal location for placing the accelerometer for predicting EE during uphill exercise is essential. Sixteen healthy male participants (M ± SEM; age 25.00 ± 0.61 years; body weight 74.13 ± 2.51 kg; body height 1.74 ± 0.01 m; body mass index 24.30 ± 0.63 kg/m2) exercised on a treadmill under 12 conditions (4 speeds and 3 gradients) on 3 days. Triaxial accelerometers, an HR recorder, and a metabolic measurement system were simultaneously used. Accelerometer outputs from various anatomical locations (upper arm, chest, lower back, waist, thigh, and instep) showed significant positive correlations with EE (0.819, 0.846, 0.816, 0.820, 0.672, and 0.669, respectively; p < .05). The linear regression equation for changes in HR showed the highest coefficient of determination (r2) of .837 with 87.9% reliability. When the HR signal was included, the r2 value (> .842) and reliability (87.9%) between the accelerometer outputs and EE improved. Accelerometer outputs from the waist position alone provide highly accurate EE values. Using both accelerometer outputs and HR for EE estimation during uphill exercise is feasible and improves the accuracy of EE prediction. 相似文献
Recent research has revealed enhanced autonomic and subjective responses to eye contact only when perceiving another live person. However, these enhanced responses to eye contact are abolished if the viewer believes that the other person is not able to look back at the viewer. We purported to investigate whether this “genuine” eye contact effect can be reproduced with pre‐recorded videos of stimulus persons. Autonomic responses, gaze behavior, and subjective self‐assessments were measured while participants viewed pre‐recorded video persons with direct or averted gaze, imagined that the video person was real, and mentalized that the person could see them or not. Pre‐recorded videos did not evoke similar physiological or subjective eye contact effect as previously observed with live persons, not even when the participants were mentalizing being seen by the person. Gaze tracking results showed, however, increased attention allocation to faces with direct gaze compared to averted gaze directions. The results suggest that elicitation of the physiological arousal in response to genuine eye contact seems to require spontaneous experience of seeing and of being seen by another individual. 相似文献
