“…Analysis of baseline psychophysiological measures indicated that men displayed greater SC levels than women (Ms = 7.40 and 4.93), F(l, 58) = 4.32, p < .05, and that women displayed greater MT levels than men (Ms = 32.87 and 19.87), F(l, 58) = 9.98, p < .01. These observations resemble earlier findings concerning gender differences in the present response modalities (summarized in Dobson & Neufeld, 1981).…”

Scenario descriptor and laboratory studies evaluated a decision-theoretic model of stress arousal and coping propensity composed of 2 stress expectancies; namely, expected stress given engagement in coping activity and expected stress given nonengagement in coping activity. The model predicted (a) that coping propensity would vary inversely with the ratio of the first stress expectancy to the second and (b) that stress arousal would vary with the lesser of the 2 stress expectancies. It was also predicted that the smallest stress expectancy would dictate coping activity and that the proximity of the stress expectancies would engender stressing response conflict. Results supported the first hypothesis when differences in ratio values were salient. The second hypothesis also was supported, but in the scenario descriptor study only. Proximity of stress expectancies as sources of stress arousal received little or no support.

“…Again, this "least upper bound" index captured the upper latitude of response during a measurement period. SC, measured this way, has been shown in experimental stress studies to be responsive to aversive stimulus properties (e.g., Dobson & Neufeld, 1981;Lefave & Neufeld, 1980;Mothersill et al, 1986;cf. Neufeld, 1975cf.…”

“…This general paradigmatic approach within the present research context has successful precedent in this laboratory, and elsewhere (e.g. Dobson & Neufeld, 1981;Endler, King, Edwards, Kuczynski, Mcguire & Diveky, 1983;Mothersill & Neufeld, 1985). Included in this past work specifically has been the stressor of physical danger/discomfort and vulnerability to its effects (Lefave & Neufeld, 1980;Mothersill, Pobson & Neufeld, 1986).…”

This study examined visual information processing under a stressor of recurring loud sound among groups divided according to psychometrically identified stress susceptibility. Formal models of task performance were employed to address several issues concerning stress effects on cognitive functioning. Examined were effects on parallel versus serial processing structure, task-wise processing capacity, strategies of allocating processing resources to task components, and curtailment of processing of relevant task elements. Contrary to prediction, stressor presence generated slightly more rather than less evidence of a parallel versus serial processing structure. There was some suggestion of central-task capacity depletion among more susceptible subjects, in line with certain theoretical positions. Evidence of curtailed exhaustive processing of relevant stimulus items was negative. Most notable was the disruption by stress among susceptible subjects of performance-enhancing strategies of deploying processing resources across the different task components (elements of the visual display and within-trial stages of processing). Such effects have received relatively little attention in this research domain; their investigation is shown to be made tractable, however, through the application of selected formal models of information processing.

“…But this value stems from a somewhat broader perspective involving the relative merits of neurochemical and electrophysiological accounts of personality variables as a "domain of explanation"; the opposing domain consists of somewhat more diffuse cognitive-behavioral accounts. For example, in assessing responses to stressing stimulation among more "anxiety prone" individuals, it has been found that neurosensory formulations surrounding this trait as put forth by Eysenck (1967;1970a) and Gray (1970; appear to be more accurate than those involving "cognitive appraisal of stress" (see Dobson & Neufeld 1981;LeFave & Neufeld 1980;Neufeld & Herzog 1983). A similar assessment may favor the biological-mechanism approach to sensation seeking as espoused by Zuckerman.…”

Sensation seeking: A comparative approach to a human trait

1984

A comparative method of studying the biological bases of personality compares human trait dimensions with likely animal models in terms of genetic determination and common biological correlates. The approach is applied to the trait of sensation seeking, which is defined on the human level by a questionnaire, reports of experience, and observations of behavior, and on the animal level by general activity, behavior in novel situations, and certain types of naturalistic behavior in animal colonies. Moderately high genetic determination has been found for human sensation seeking, and marked strain differences in rodents have been found in open-field behavior that may be related to basic differences in brain neurochemistry. Agonistic and sociable behaviors in both animals and humans and the trait measure of sensation seeking in humans have been related to certain common biological correlates such as gonadal hormones, monoamine oxidase (MAO), and augmenting of the cortical evoked potential.The monoamine systems in the rodent brain are involved in general activity, exploratory behavior, emotionality, socialization, dominance, sexual and consummately behaviors, and intracranial self-stimulation. Preliminary studies have related norepinephrine and enzymes involved in its production and degradation to human sensation seeking. A model is suggested that relates mood, behavioral activity, sociability, and clinical states to activity of the central catecholamine neurotransmitters and to neuroregulators and other transmitters that act in opposite ways on behavior or stabilize activity in the arousal systems. Stimulation and behavioral activity act on the catecholamine systems in a brain–behavior feedback loop. At optimal levels of catecholamine systems activity (CSA) mood is positive and activity and sociability are adaptive. At very low or very high levels of CSA mood is dysphoric, activity is restricted or stereotyped, and the organism is unsocial or aggressively antisocial. Novelty, in the absence of threat, may be rewarding through activation of noradrenergic neurons.
