The catastrophic misinterpretation model of panic disorder.

In the catastrophic misinterpretation model of panic Clark [Behav. Res. Ther. 24(1986)1461] proposes that panic attacks result from the misinterpretation of autonomic arousal stimuli as precursors to a physical or psychological emergency. The model has been widely examined, with many researchers suggesting that this specific cognitive bias is implicated in both the phenomenon of panic, and the aetiology and maintenance of panic disorder. Various research methodologies have provided only partial or inconclusive support for the model as being uniquely associated with panic, and as a cognitive process underpinning the experience of panic. This paper reviews the body of existing evidence and its implications for the model and proposes future research directions. The influence of implicit operational definitions of key terms in the catastrophic misinterpretation literature (e.g. 'catastrophe', 'threat', 'anxiety-related') are examined, and clarifications proposed. Inconsistencies and limitations in the measurement of catastrophic misinterpretation are highlighted, and subsequently developments to measurement instruments are proposed.     

How Separable Are Spirituality and Theology in Psychotherapy?

The authors respond to D. A. Helminiak's (2001) article “Treating Spiritual Issues in Secular Psychotherapy.” They focus particularly on Helminiak's argument for secular spirituality (whether spirituality can be independent of theology/religion) and his inherent biases in discussing the nature and existence of spirituality. The authors argue that all spiritual conceptions have theological implications—and thus a theology, broadly defined—and that theology, in this sense, pervades the theory and practice of all psychotherapists, whether or not they are religious.     

The influence of sphincter control and genital sensation on body image and gender identity in women.

The development of one aspect of feeling female is hypothesized to account for certain phenomena in the treatment of young women patients. Fear of loss of genital pleasure experienced as contractions of the anal and genital-urinary sphincters is seen as the central issue in conflicts manifested in genital, oral, and anal modalities. It is suggested that the female's awareness of her genital arises from the generalization of sphincter sensation in the little girl, which is then represented in the body image. The body image is postulated as a link between genital pleasure and the valuing of femininity.     

Distributional theories of impression formation

This paper examines theories of impression formation which represent stimulus information as distributions on subjective dimensions rather than points along a continuum. These theories explain why unfavorable information often overrides favorable information. Subjects were asked to imagine hypothetical persons described by single adjectives or adjective combinations and to estimate the probability that each person would have various degrees of likeableness. Three models were considered to describe how the likeableness distribution for the adjective combination depends on the distributions of the single adjectives. All three models assume that the mean of the distribution for the adjective combination is described by the equal probability criterion which, for symmetric distributions, implies a weighted average of the single adjective means with weights inversely proportional to their standard deviations. The models can be distinguished on the basis of the standard deviations of the adjective combinations. Estimated standard deviations of the single unfavorable adjectives were smaller than those for the single favorable adjectives. Furthermore, the standard deviation associated with an adjective combination tended to fall between the standard deviations of the single adjectives, consistent with the horizontal averaging model.     

Gender differences in the effectiveness of coping with dysphoria: A longitudinal study

This study examined whether men use more eflective means of coping with dysphoria on their own than do women. Forty-four male and female college students who reported feeling dysphoric were evaluated on their coping styles at three intervals in a six and a half week time span. The findings suggest that men and women do not use significantly different appraisal and coping techniques. For both sexes, problem-focused coping was associated with less dysphoria over time, whereas emotion-focused coping was associated with more dysphoria over time. Keeping anger in was associated with more dysphoria over time for women. In addition, the way in which the situation was appraised influenced the level of dysphoria over time for both sexes.     

Eysenck's incubation of fear hypothesis: an experimental test

The present experiment was designed to test Eysenck's hypothesis that repeated exposure to an unreinforced CS of brief duration following acquisition of a classical aversive CR may lead to a progressive increase in the strength of that CR, provided that the UCS is intense and the CR has drive-like properties. Using a between-groups design, normal human subjects were given identical classical acquisition trials, followed by extinction trials where CS duration was either 2, 8 or 16 sec. The UCS was of fixed high intensity. Dependent measures were tonic and phasic heart rate and skin conductance. No evidence of incubation was found as a function of CS duration. Nor was there any indication that CS duration differentially affected resistance to extinction. A small number of subjects showed evidence of incubation with heart rate measures during extinction. However, there was no indication that this enhancement was governed by the parameters suggested by Eysenck. UCR amplitude, which showed a positive correspondence with CS-bound activity throughout the trials, did not reliably predict incubation. Problems concerning both the definition and the demonstration of incubation are discussed.     

Inhibitory stimulus control and the magnitude of delayed reinforcement

The key pecking of pigeons was reinforced according to a variable-interval 1-min schedule during each of two successively presented stimuli. When the key was illuminated by a black line on a white background, reinforcement was delayed for 10 sec. When the key was illuminated by a plain white light, reinforcement was not delayed. For half of the subjects, the delayed reinforcer was 4.0-sec access to mixed grain, and for the remaining subjects it was 1.5-sec access. The immediate reinforcer was 1.5-sec access for all subjects. All subjects responded at a lower rate during the presentation of the black line; no between-group difference in terms of terminal response rate during the presentation of the line was found. However, subjects that received 4.0 sec of delayed reinforcement responded at a lower terminal rate during presentation of the plain white light than subjects that received 1.5 sec of delayed reinforcement. A subsequent generalization test along the line-orientation dimension produced flatter U-shaped gradients for subjects that received 4.0-sec of delayed reinforcement.     

The psychology of farming: A review of twenty-five years of research

If all of mankind is to have an adequate diet, we must both stabilize world population and increase markedly world food supply. Moreover, attaining any such increase in food supply may be as much a problem in vocational psychology (e.g. the skill, knowledge, openness to change, and motivation of farmers) as in agricultural technology. The purpose of this review is to further psychological work on agricultural productivity by listing and evaluating a cross-section of relevant articles since 1945. Because psychologists have largely ignored agriculture, most reviewed studies were conducted by other behavioral scientists. Studies are grouped according to three broad areas: (1) predictors of choice, success, and satisfaction; (2) adoption of recommended practices; and (3) communal agriculture.     

Aversive properties of the negative stimulus during learning with and without errors

In a successive discrimination four groups of pigeons were trained to discriminate between red and green. The groups differed with respect to the procedure used to introduce S?: Early-Progressive, Early-Constant, Late-Progressive, and Late-Constant. The aversive properties of S? were measured by an escape response in which a single peck at a second key terminated S? for 10 sec and darkened the chamber. The correlation between the aversive and error-producing properties of extinction was zero. More errors occurred when S? was introduced abruptly at a constant intensity while more timeouts from S? occurred when S? was introduced late. The procedure for introducing S? rather than the number of responses to S? appears crucial in determining how aversive S? becomes.
