PUPILLARY AND ELECTROMYOGRAPHIC CHANGES DURING AN IMAGERY TASK

This study examined the relationship between muscle activity and the increased pupillary dilation observed during cognitive tasks when S is required to indicate task completion. Pupillary and EMG activity were monitored while Ss generated images to words. In two groups, Ss indicated completion of the task either by pressing a key or by releasing it. In two other groups Ss made a key press response that was unrelated to the cognitive task. No key press was required of a fifth group. Results indicated some apparent effect of muscle activity on pupil size during the imagery task and the findings were discussed in relation to other variables affecting pupillary activity.     

Modern Mind-Brain Reading: Psychophysiology, Physiology, and Cognition

This paper reviews the actual and potential benefits of a marriage between cognitive psychology and psychophysiology. Psychophysiological measures, particularly those of the event-related brain potential, can be used as markers for psychological events and physiological events. Thus, they can serve as "windows" on the mind and as "windows" on the brain. These ideas are illustrated in the context of a series of studies utilizing the lateralized readiness potential, a measure of electrical brain activity that is related to preparation for movement. This measure has been used to illuminate presetting processes that prepare the motor system for action, to demonstrate the presence of the transmission of partial information in the cognitive system, and to identify processes responsible for the inhibition of responses. The lateralized readiness potential appears to reflect activity in motor areas of cortex. Thus, this measure, along with other psychophysiological measures, can be used to understand how the functions of the mind are implemented in the brain.     

Psychophysiological Correlates of Electrodermal Lability

This study of 75 college student subjects investigated the psychophysiological correlates of electrodermal lability. Resting-stabile and resting-labile subjects were defined as those who were respectively below and above the median of all same-sex subjects in frequency of nonspecific skin conductance responses during rest, whereas stimulus-stabile and stimulus-labile subjects were those respectively below and above the median in trials to habituation of the skin conductance orienting response. These two classification systems were found to be highly correlated with one another, but not entirely equivalent. With both lability measures, labiles had higher resting skin conductance levels than stabiles and also exhibited larger skin conductance orienting responses to both signal and nonsignal tones. Labiles produced orienting responses with shorter latencies, rise times, and half recovery-times. Resting-labiles also differed from resting-stabiles in the components of the triphasic heart rate response to the tones, having larger decelerative responses. The data are consistent with the view that labiles are better able than stabiles to allocate attentional capacity to environmental events and to respond to changing demands in an attentional situation.     

Psychophysiological Predictors of Attentional Dysfunction in Children with Congenital Heart Defects

Cardiac responses to non-signal stimuli and to signal stimuli in a vigilance task were examined in children born with congenital heart defects (CHD), and in normal and attention deficit disordered (ADD) subjects. Overall task performance was lower in subjects with heart defects and in the ADD group. Cardiac measures revealed that normal children displayed significantly larger heart rate deceleration to the target stimuli than did either of the clinical groups. Moreover, although no group differences were observed in the cardiac response to non-signal auditory stimuli, exaggerated heart rate deceleration was observed to vibrotactile stimuli in both the clinical groups. Regression analyses revealed that the magnitude of the cardiac response to somatosensory stimuli was predictive of task performance (both within and between subject groups), with larger responses associated with higher error rates and lower perceptual sensitivity. Results were suggestive of a predictive relationship between somatosensory reactivity and neuropsychological maturation.     

认知评价、心理控制源、社会支持与大学生就业压力关系的研究

目的 探讨认知评价、心理控制源、社会支持与大学生就业压力关系.方法 采用问卷法,随机选取某高校400名毕业生为被试,研究认知评价、心理控制源、社会支持与大学生就业压力关系.结果 ①积极认知评价、心理控制源和社会支持与大学生就业压力有显著负相关,而消极认知评价、心理控制源和社会支持与就业压力有显著的正相关.②消极认知评价、心理控制源和社会支持对就业压力有直接影响;而积极的认知评价通过心理控制源和社会支持间接影响大学生就业压力.③通过调查,在社会支持方面,女生对社会支持的寻求显著高于男生,男女生在情感表现上有明显的差异.结论 认知评价、心理控制源、社会支持与大学生就业压力关系呈显著相关.     

Group treatment for pain and discomfort

Rheumatic patients very often suffer from chronic pain and impairment and show psychological reactions as a consequence of their physical condition. These reactions may vary from psychophysiological symptoms to anger, anxiety, or depression. We developed a cognitive-behavioral treatment programme in a group setting format with components of relaxation, cognitive restructuring, and the promotion of well-being. Subjects included in the study were given diagnoses of low back pain, tension headache, rheumatoid arthritis, and ankylosing spondylitis. Treatment effects in different diagnostic groups were compared to each other, supporting the assumption that pain reduction is greatest in low back pain and least in ankylosing spondylitis. Subjects with inflammatory rheumatic diseases showed some improvement in self-reported physical complaints and in their feelings of well-being.

Periodic breathing and genetics

The episodic waxing and waning of ventilation is a fundamental event in sleep apnea syndromes. Post-hypoxic frequency decline (PHFD) and periodic breathing (PB) are evoked by brief hypoxic exposures in unanaesthetized and unrestrained inbred C57BL/6J mice, but not in A/J mice; and expression of PHFD differs not only among these mice strains but in among rat strains as well. These observations along with the current literature on genetic factors that operate on ventilatory behavior at rest and with chemosensory drive lead to the hypothesis that genetic factors infer some proportion of risk for the ventilatory instability observed in human sleep apnea syndromes.
