Activity Versus Reactivity in Psychology and Neurophysiology
Ecological Psychology, 1993The traditional reflex approach in neurophysiology is incompatible with modern psychology's concern with goal-directed activity. We try to show that a ne~roph~siological approach based on the theory of functional systems may help to solve this problem.

Pupillary Reactivity, Psychologic Disorder, and Age
Archives of General Psychiatry, 1966FOR MANY years, it has been hoped that in addition to overt behavioral deviations, covert physiologic deviations might be found in patients with various kinds of mental disorder which would be of assistance in classifying, understanding, and treating the illness. In keeping with this possibility, the notion has often enthusiastically been advanced that

Emotional Reactivity and Psychological Distress
Journal of Adolescent Research, 2002A primary purpose of this article was to test part of Bowen’s intergenerational family systems theory. A secondary purpose was to provide further evidence for the construct validity of a newly developed instrument that assesses differentiation of self. Using Bowen’s family system theory, a model was developed that hypothesized both direct and indirect

Reliability of Heart-Rate Reactivity to a Psychological Stressor
Perceptual and Motor Skills, 1989Reliability of heart-rate reactivity responses to a timed and competitive mental arithmetic stressor was investigated in a sample of 40 students. Analysis indicated that significant differences between groups of high and low heart-rate reactivity subjects were consistent over a period of 4 to 6 wk., with no significant effects from mental arithmetic ...

Physiological and psychological stress reactivity in chronic tinnitus
Journal of Behavioral Medicine, 2008Several models of tinnitus maintenance emphasize the importance of cognitive, emotional and psychophysiological processes. These factors contribute to distress in patients with decompensated tinnitus symptoms. We investigated whether tinnitus patients show increased physiological levels of arousal, more intense stress reactivity patterns and ...

Cardiac denervation and cardiovascular reactivity to psychological stress
American Journal of Psychiatry, 1994This study investigated the mechanisms responsible for increases in heart rate and blood pressure during psychological stress, which are incompletely understood. Since cardiac transplant patients have denervated hearts, they provide a unique model for isolating central versus peripheral influences on the cardiovascular response to stress.The authors ...

Cardiovascular Reactivity to Psychological Stress in Healthy Children
Psychophysiology, 1988ABSTRACTCardiovascular reactivity to stress has been implicated as a marker and/or mechanism in the development of cardiovascular disease. No normative data exist to classify children's reactivity to psychological stress. This investigation presents normative percentile data on the hemodynamic responses (heart rate and blood pressure) of 310 healthy ...

Genetic analysis of autonomic reactivity to psychologically stressful situations
Biological Psychology, 2001We present the results of a behavioural genetics study on response profiles of autonomic measures (heart rate, blood pressure, and galvanic skin level), under ecologically valid, stressful conditions. Where response profiles of different physiological variables are the object of study, and when daily life stressors are taken into account (Turner and ...

Psychological and Neuroendocrine Reactivity to Ostracism
Aggressive Behavior, 2012This study used the ostracism detection theory to investigate how ostracism impacts individuals in two ways: (1) immediate poststressor needs, mood, ruminative thoughts, and desire to affiliate, and (2) short‐term affective and cortisol reactivity.

Life Event Exposure, Physiological Reactivity, and Psychological Strain
Journal of Behavioral Medicine, 2000The study tested the prediction that the experience of life events would be reflected in greater autonomic reactivity and that this might play a moderating role between reported stress and psychological symptoms. Eighty-seven undergraduates were screened with a life events scale and thirty-nine were allocated to three groups representing high, medium ...
