A commentary on Gray's critique of Eysenck's theory

Gray (1982a) criticizes Eysenck's theory of personality and offers his own alternative theory. In this article it is suggested that, for the most part, Gray's criticisms are not substantial. Little damage is sustained by the ‘Eysenckian edifice’ although it is proposed that the means of testing Eysenck's ‘conditionability’ hypothesis should be re-examined. Consideration of Gray's theory leaves one with the conviction that it is coming under increasing pressure as evidence accumulates concerning the mechanisms of the ‘anti-anxiety’ drugs. Apart from this and other problems, Gray's formulation is constructed within a narrow and specialized universe of discourse that does not relate well to the more global concerns of those who study personality. Without reference to Eysenckian concepts, Gray's theory is really only concerned with ‘anxiety’. For this reason it can barely be termed a theory of personality let alone one that might replace the Eysenckian paradigm.     

A neurotransmitter basis for Eysenck's theory of personality

A physiological basis for Eysenck's theory of personality is proposed which is different from those bases suggested by Eysenck himself. Psychoticism, neuroticism and extraversion are associated with varying levels of dopamine, serotonin, and norepinephrine, respectively.     

Multiple systems: A new approach to cognitive theory

Abstract

Cognitive processes turn out to be both more innate and more culturally based than we used to think. On the one hand, ecological and interpersonal perception are innately prepared, available in infancy; on the other, mental development depends critically on social support. Taken together with the emerging multiple/modular structure of the brain, these discoveries demand a new kind of cognitive theory: an ecologically grounded, developmental account of distinct systems in interaction. Three such systems, primarily perceptual in function, are described here: (1) direct perception/action establishes an immediate non-representational sense of self and environment that grounds all other cognition; (2) interpersonal perception/reactivity produces species-specific patterns of social interaction; (3) recognition/representation identifies and classifies what is perceived. These systems are distinguished by neurological as well as psychological criteria: the neuroanatomical “where/what” distinction, for example, reflects the difference between direct perception and recognition. Cooperation among these three systems, which begins near the end of the first year, is basic to language and other forms of cultural learning.     

Eysenck's theory of incubation: an empirical test

Eysenck's incubation of fear hypothesis that states that repeated CS-alone presentations can yield an increase in measures of fear was tested by first giving rats either a paired or an unpaired presentation of a tone CS and either a strong (3.5 mA), weak (1.05 mA) or no-shock US and then 10 daily CS-alone presentations. Over the CS-alone trials, conditioned fear, as measured by duration of freezing, latency to escape and activity scores, extinguished, rather than incubated.     

Eysenck's theory of personality and child-adult emotional attachments

The present study was mainly designed to examine the link between child-adult emotional bonds and personality characteristics. A sample of Pakistani adolescents aged between 13 and 14 completed the Emotional Attachment Scale and the Eysenck Junior Personality Questionnaire. Adult subjects to whom the adolescent subjects were predominantly emotionally attached were also asked to complete the Eysenck Adult Personality Questionnaire. The results indicated that children tend to develop emotional attachments to those parents whose personality scores correlate significantly positively with theirs; however, if they attach to nonparent adults, no significant association between their personality scores and those for adults exists.     

A category theory approach to cognitive development

The category theory concept of a commutative diagram is used to construct a model of the way in which symbolic processes are applied to problem solving. The model provides for a relationship between symbolic processes and the problem which depends on structural isomorphism and consistency, but is independent of similarity between symbol elements and problem elements. It is then shown that several different levels of thought can be distinguished within the basic model. More information is needed to assign symbolic processes to a problem in a consistent way with higher-level thought processes than with lower-level processes. These information-processing requirements permit the approximate age of mastery of each level to be predicted, thereby offering an alternate theory of cognitive developmental stages. Two experiments designed to test the theory are reported.     

A psychometric investigation of Eysenck's personality inventory

Eysenck's personality inventory (EPI) was administered to 653 females and 666 males. Item analyses were carried out for the subsamples and the combined sample. In addition hierarchical oblique factor analysis was applied to the data. The purpose of both item and factor analysis was to examine the psychometric properties of the EPI in regard to (a) the homogeneity of the scales, in terms both of internal and external item-scale relationships (b) the univocality of the scales assessed in factor analytic terms. It was found that the neuroticism scale was superior to the extraversion scale in both these respects.     

A new approach to explain aggression

Two separate experiments are reported. They show the methodological difficulties and subsequent conceptual complications in Berkowitz's modified frustration-aggression theory and Zillman's theory of aggression. There was a marginally significant difference in the verbal measure of aggression favouring subjects aroused by frustration over subjects aroused by exercise, but not on the behavioral measure of aggression. Exp. II was conducted to test an alternative hypothesis, deduced from Fraisse's theory of emotion, which states that subjects respond more aggressively when confronted with unexpected than with expected annoyance. All six measures of aggression confirmed the hypothesis. The results of these two experiments indicate conceptual and methodological difficulties inherent in Berkowitz's modified frustration-aggression theory and Zillman's theory of aggression; they also suggest that Fraisse's theory of emotion presents a better model of aggression.

A new approach to manipulation arguments

There are several argumentative strategies for advancing the thesis that moral responsibility is incompatible with causal determinism. One prominent such strategy is to argue that agents who meet compatibilist conditions for moral responsibility can nevertheless be subject to responsibility-undermining manipulation. In this paper, I argue that incompatibilists advancing manipulation arguments against compatibilism have been shouldering an unnecessarily heavy dialectical burden. Traditional manipulation arguments present cases in which manipulated agents meet all compatibilist conditions for moral responsibility, but are (allegedly) not responsible for their behavior. I argue, however, that incompatibilists can make do with the more modest (and harder to resist) claim that the manipulation in question is mitigating with respect to moral responsibility. The focus solely on whether a manipulated agent is or is not morally responsible has, I believe, masked the full force of manipulation-style arguments against compatibilism. Here, I aim to unveil their real power.
