Contextual stimulus control of conditional vasomotor and electrodermal reactions to angry and friendly faces

An experiment with 42 human Ss used the transswitching procedure to examine tonic stimulus control of phasic and tonic conditioned vasomotor heart rate, and electrodermal reactions. The conditional stimulus (CSs) were photos of angry and friendly human faces, and the unconditional stimulus (US) was a human scream. In one tonic context (blue light), the CSs were paired with the US, in the other context (yellow light), the CSs were presented unpaired. Following acquisition, an extinction series was run with the US omitted during both tonic contexts. Phasic vasomotor and skin conductance reactions differed in the positive and negative tonic segments (stronger in positive). The skin conductance responses also differed during extinction, but the vasomotor responses did not. Tonic differences (following onset of the tonic stimuli) in unelicited skin conductance response frequency, finger pulse volume, and heart rate were also found, although these developed more slowly than the phasic differences. The finger pulse volume tonic difference was greater in extinction than the skin conductance response frequency. There was no effect of the angry-friendly facial expressions, either directly or in interaction with the transswitching effects. The results were interpreted to mean that the transswitching phenomenon is not limited to one another autonomic effector, but is more generalized across the ANS (sympathetic branch). The absence of influence of the facial expressions indicates the relative weakness of the “preparedness” hypothesis in comparison with more influential contextual factors.     

The borderline hypertensive rat (BHR): A new model for the study of environmental factors in the development of hypertension

While many studies have attempted to produce hypertension through the use of various environmental Stressors, few have succeeded in producing chronic elevations in blood pressure beyond levels considered to be borderline hypertensive (140–160 mm Hg systolic). The problem with most studies stems from the use of genetically normotensive animals and the selection of Stressors to which animals readily adapt. A new approach is suggested, which recognizes the role of genetics in human essential hypertension. Animals with one hypertensive parent do not develop spontaneous hypertension but show a more sensitive cardiovascular response to environmental Stressors than animals with normotensive parents. Preliminary studies revealed that animals with a mixed genetic history of hypertension develop spontaneous borderline hypertension. When subjected to shock-shock conflict, these borderline hypertensive rats (BHR) developed permanent hypertension that failed to abate even after a ten-week, shock-free recovery period. The hypertension was accompanied by elevated heart weight to body weight ratios and by significant cardiac pathology. Subsequent work has demonstrated that these animals also become hypertensive when fed a high-sodium diet. Finally, in a series of exercise studies, we found that BHRs subjected to a shock stressor were protected against stress-induced hypertension if they exercised daily. The potential of this model for studies of the mechanisms by which environmental variables produce permanent hypertension is discussed.     

Imposture, inauthenticity, and feeling fraudulent

This paper deals with imposturous tendencies as ubiquitous and heterogeneous. They may enter into neurotic conflict and compromise, and also reflect an ego function disturbance involving multiple, shifting identities and subsequent problems in the subjective sense of reality of the self and objects. Imposture in a person undergoing analysis is, however, not only a function of individual character and psychopathology; it is also a function of certain inevitable requirements of the analytic situation which constitute a "pull" for its emergence. Vulnerable individuals will respond to this pull in revealing ways. Three case summaries illustrate the spectrum of imposturous tendencies.     

Spatial location judgments as a function of intention to learn, and mood state: an evaluation of an alleged automatic encoding operation

An assessment of the Hasher and Zacks (1979) conceptualization of the automatic nature of the acquisition of spatial location information was made in the context of manipulations of subjects' intention to learn and mood state. The Velten (1968) mood induction procedure was used to establish depressed and nondepressed subjects. Half of each group was then presented with a matrix of geometric forms under instructions to learn the location of the forms (intentional) or to evaluate the pleasantness of the array (incidental). Subsequent tests of spatial location performance found no differences as a function of subjects' mood state, but did find a strong effect for instructional condition. The superior performance of the intentional subjects raises questions about the automatic nature of the encoding of spatial location.     

Superego formation, adolescent transformation, and the adult neurosis

The superego is heir to the Oedipus complex but has a much larger developmental legacy which includes preoedipal precursors and the influence of latency and adolescence. The superego continues to change in function and content throughout life, and radical transformation in adolescence may result in developmental discontinuity as well as core developmental continuity. A case is discussed in which adolescence was overlooked in previous analysis and in which adolescent superego modification had a major impact on the patient's character and his adult neurosis. The developmental significance of adolescence experienced under conditions of social isolation and rejection with forebodings of the Holocaust was unrecognized in sanctioned silence and shared analytic denial. These repeated earlier experiences of silent submission and stifled protest, and the silent suffering of the patient and his family, were an integral part of his humiliating and emasculating adolescent experiences. The intimidated adolescent, threatened from within and without, identified with the aggressor as well as with the victim. Identification with the aggressor and glorified victor contributed to a final adolescent structuralization of a punitive, sadistic superego and a rigidly perfectionistic ego ideal. As an adult, he tended to passive masochistic compliance with diminished self-esteem and unconscious self-denigration. He was prone to shame and guilt, self-criticism, and hidden hypercritical attitudes toward others. The adolescent internalization of aggression, intense castration anxiety, and pervasive narcissistic mortification led to retreat from resolution of revived oedipal conflict and to concomitant detrimental superego alteration. These issues were of major importance for analytic understanding and therapeutic progress.
