Psychophysiological arousal related to Type A components in adolescent boys

The association between psychophysiological responses (heart rate, skin conductance and blood volume) and Type A behavior was studied in adolescent boys (n = 48) in computer-controlled experiments. Although psychophysiological arousal was related to the type of stress-evoking element, task-specificity did not result in significant psychophysiological differences between Type As and Nontype As. The indication is that physiological arousal may be a constitutional characteristic of Type A behavior. The multidimensionality of type A behavior must be considered in any investigation examining the psychophysiological Type A-Nontype A differences. Different Type A dimensions, together with previously found psychological differences, were related to specific psychophysiological reactions.     

Individual response differences in spider phobia: Comparing phobic and non-phobic women of different reactivity levels

Abstract

In contrast to previous stress research, studies concerning phobic disorders have never systematically investigated individual response differences between phobic participants integrating numerous different response measures. The aim of this article is to clarify the existence of significant individual response differences in psychophysiological responses (e.g., heart rate, skin conductance responses (SCR), corrugator, cortisol), subjective ratings (e.g., valence, arousal), and avoidance behavior in 46 spider phobic and 44 non-phobic women when exposed to 20 phobic and 20 neutral pictures. Previous studies that did not attend to individual response differences showed that, during phobic stimulation, phobic individuals have increased psychophysiological responses (heart rate, SCR, and corrugator responses), more negative valence rating, and more subjective arousal than non-phobic individuals. These results were confirmed by our data. With regard to individual response uniqueness, 1/3–2/3 of spider-phobic women with low responsiveness in heart rate, cortisol, and avoidance behavior were indistinguishable from non-phobic women during phobic stimulation. With SCR, corrugator EMG, and subjective ratings, no individual response uniqueness was found. Based on the findings, exposure therapy might be improved by tailoring interventions to individuals with a therapeutic focus on those psychophysiological measures that show the highest individual responsivity.

A Review of Experimental Research on Embodied Creativity: Revisiting the Mind–Body Connection

A growing body of experimental work highlights the potential value of unstructured, interactive, or spontaneous motions, including gestures, dance, shifting body postures, physical object-manipulation, drawing, etc. to favorably impact creative performance. However, despite these favorable findings, to our knowledge, no systematic review has been conducted to explore the totality of evidence for embodied activities in this arena. Thus, the objective of this paper was to systematically evaluate the potential effects of embodied experimental manipulations on traditionally assessed creativity outcomes. A systematic review was conducted utilizing PubMed, PsychInfo, Sports Discus, and Google Scholar databases. The 20 studies evaluated employed a variety of methodological approaches regarding study design, embodied manipulation, and selection of specific creativity outcomes. Despite these variations, embodied movement robustly enhanced creativity across nearly all studies (90%), with no studies showing a detrimental effect. Based on the evaluation of the studies reviewed, several common themes emerged. These included the relevance of symbolic metaphors and distributed embodied cognitions, selection of embodied modality, specific measurement considerations, as well as the importance for implementing true, inactive control conditions in embodied creativity research. This review expands on these findings and places them in the context of improving future embodied creativity research.     

Consistency of social anxiety in psychiatric patients: Properties of persons,situations, response classes,and types of data

The focus of this study was to investigate the consistency of observed overt behaviors, psychophysiological measures, and reported cognitions in high and low socially anxious psychiatric patients. Forty-seven psychiatric patients (25 high and 22 low socially anxious ones) were exposed to two situations: the initiation of a conversation and the refusal of a request. For both groups of subjects, consistency across situations (Situations) and trait indicators (Reactions) was highest for psychophysiological measures. Observed overt behaviors showed the lowest consistency across Situations and Reactions. Substantial evidence was found for the consistency of Persons x Situations and Persons x Reactions interactions. Moreover, high socially anxious subjects showed a higher consistency than low socially anxious patients with respect to observed overt behaviors and reported cognitions. Using psychophysiological measures, low socially anxious patients showed higher consistency than high socially anxious subjects. The implications for the assessment of social anxiety are discussed.     

TYPES OF PRAYER,HEART RATE VARIABILITY,AND INNATE HEALING

Spiritual practices such as prayer have been shown to improve health and quality of life for those facing chronic or terminal illness. The early Christian healing tradition distinguished between types of prayer and their role in healing, placing great emphasis on the healing power of more integrated relational forms of prayer such as prayers of gratitude and contemplative prayer. Because autonomic tone is impaired in most disease states, autonomic homeostasis may provide insight into the healing effects of prayer. I report on observations in five volunteers engaging in five types of prayer. Using heart rate variability as a measure of autonomic tone and adaptability, I review the potential correlation of type of prayer with autonomic rebalance as measured specifically by psychophysiological coherence ratios. The five types—supplication, devotion, intercession, gratefulness, and contemplative prayer—elicited varying degrees of improvements in heart rate variability and corresponding psychophysiological coherence. These observations suggest a correlation of innate healing to prayer type that is consistent with teachings from the Christian healing tradition and with modern research. Further research is warranted to verify these hypotheses.     

Inter- and intrasession reliability of psychophysiological poststress adaptation periods

This study examined the intersession and intrasession reliability of poststress adaptation periods. Fifteen undergraduates were assessed four times on measures of cephalic vasomotor response, electromyography (EMG; frontal and forearm flexor), hand surface temperature, heart rate, and skin resistance level. The results indicated no consistent intersession reliability of these measures and good intrasession reliability of all measures except frontal EMG. A 3- min poststress adaptation period was all that was necessary for most measures, again with the exception of frontal EMG, to return to a baseline quiescent state. These results are discussed in terms of the effect these findings have on theories of psychophysiological disorders which postulate impaired recovery processes.The author gratefully acknowledges the contributions of Drs.

The coregulatory effects of emotionally focused therapy

This study examined the heart rate synchrony between a single couple in emotionally focused therapy (EFT) as a method of measuring coregulatory effects over the course of treatment. A clinician who is an EFT certified therapist, supervisor, and trainer administered all eight sessions in a private practice setting. Surrogate synchrony analysis assessed heart rate synchrony between partners, indicating that significant heart rate synchrony was more likely over time. Significant heart rate synchrony was more likely during sessions that focused on clients’ sharing attachment injuries, bonds, and longings with their partner compared to sessions more focused on cognitive processing of the relationship. Additionally, there were delays in heart rate synchrony that occurred between the couple, which may be indicative of the emotional processing speed of the empathic response of each partner. Understanding the physiological synchrony patterns between dyads in treatment could clarify the potential of coregulation in the therapeutic process.     

基于fMRI的自上而下字母加工神经机制的研究

人们在识别自己所熟悉的物体时, 不仅依赖于对输入信息的感知而且还会受到自上而下调节机制的影响。研究者基于功能磁共振成像(fMRI), 利用虚幻探测范式对自上而下字母加工的神经网络进行研究。该研究要求被试从纯噪声(实际没有任何字母)中探测字母。通过对fMRI数据进行心理生理交互效应分析, 发现当被试从纯噪声图片中“看”到字母时, 多个脑区的活动由于受到来自于右侧梭状回的影响而加强。该发现表明自上而下的字母加工网络不但包含负责字母形状和语音加工的脑区, 还涉及一些负责高级认知加工的区域。
