An exploratory investigation of the origin and maintenance of phobias

Phobies were asked to relate past events which they believed caused or contributed to their fear, and to describe cognitive events experienced while imagining phobic interactions. Approximately half the subjects were able to recall relevant learning experiences, with direct experiences far more common than vicarious experiences or learning based on verbal instruction. Almost all of the subjects reported self-verbalizations while imagining the phobic situation, in every case phobic relevant. However, in a minority of instances were the verbalizations ‘catastrophic’ in nature. In only about half the cases did the phobies report that, in vivo, thoughts preceeded fear in the phobic situation (in contrast to a comparison group of less fearful subjects for which thoughts did preceed fear to a significant degree). Results are discussed in terms of possible limitations of a cognitive interpretation of phobic behavior.     

Validity of Adler's active-constructive,active-destructive,passive-constructive,and passive-destructive typology

This research investigated the validity of Adler's typology: active-constructive, achievement-oriented; active-destructive, hostile; passive-constructive, attention-seeking; and passive-destructive, interpersonal detachment. Four possible measures of the constructive-destructive dimension and two possible measures of activity-passivity were used, with all eight possible combinations being used to establish the Adlerian types (active-constructive, etc.). A total of 192 male undergraduates served as subjects. The Full I-E Scale in combination with the CPS Activity-Lack-of-Energy Scale produced groups that demonstrated the Adlerian relationships, active-constructive, achievement-oriented, and so forth. There were strong secondary personality manifestations within the respective groups.     

Acquisition of cognitive compiling

Language involves both structure and process. Giving each its due, we present a cognitive process model and show how its empirical success is related to claims about syntactic structure. Innate constraints on syntax are a central issue in linguistic theory, so it is a matter of concern that a widely accepted view of phrase structure constraints (X-bar theory) appears to be violated in some recent comprehension experiments with children. However, what is directly observed in the experiments is not a syntactic structure but the execution of a plan. We present a language of process for representing such plans and thereby provide a unified explanation of several developmental phenomena, including the results of the above experiments and of new experiments suggested by our approach. The explanation is in terms of the cognitive resources required to formulate and execute a plan. Since the explanation is based on nonsyntactic processing, the children's syntax need no longer be held faulty. This conclusion invigorates the claim that the range of phrase structures available to children is biologically constrained.     

Semantic integration: Effects of imagery,enaction, and sentence repetition training on prereaders' recall for pictograph sentences

This study examines the effectiveness of an integrative imagery strategy in contrast to more concrete enaction and repetition strategies for improving kindergarten children's recall of pictograph sentences. The training groups were taught in two brief sessions to read the pictograph sequences as sentences and then to imagine the sentence's action (sentence imagery), act out the sentence using toys (sentence enaction), or repeat each sentence twice (sentence repetition). After training, the enaction group significantly outperformed the imagery and sentence repetition groups, which outperformed a repetition control group. Two weeks later, the imagery and enaction groups no longer differed significantly in recall and both groups significantly outperformed the repetition control group. The imagery group alone significantly outperformed the repetition control group on a no-toys generalization test. Implications of the results concerning strategy training of young children, the effectiveness of imagery strategies, and experimental design are discussed.     

Facilitation of retention by white noise.

Second and fifth grade subjects were given three verbal tasks: serial, free recall, or paired-associate learning. Retention tests were administered immediately after the acquisition phase or following a long delay. Half the subjects were exposed to a 2-min period of bursts of white noise (arousal) immediately prior to the retention test. The finding of primary interest was that white noise produced substantial improvement in performance relative to a control condition. This effect may be more pronounced for long-term memory than for short-term memory. Although older children exhibited better long-term memory than younger subjects, no interaction of age with arousal condition was observed.     

Interviewer evaluations of interviewee nonverbal behavior

Personnel representatives (N = 52) were shown one of four videotaped job interviews in which the verbal content of the 16-min interview was identical, but the interviewee's nonverbal behavior was manipulated. A “low nonverbal” interviewee was defined by minimal eye contact, low energy level, lack of affect and voice modulation, and a lack of speech fluency. The “high nonverbal” interviewee demonstrated the opposite behavior on each of these components. The subjects were asked to rate the videotaped candidates on dimensions previously identified as critical in influencing a job interviewer's decisions. Nonverbal behavior was found to have a significant effect on almost every rating made by subjects in this study. After reviewing the entire 16-min interview, 23 of the 26 subjects who saw the “high nonverbal” candidate would have invited him/her for a second interview. All 26 of the subjects who saw the “low nonverbal” candidate would not have recommended a second interview.     

Social conditioning and its proper control procedures.

In Expt I, eight infants received response-contingent social stimulation, while another eight infants received response-independent social stimulation. Both groups' vocalization rates similarly increased from baseline to stimulation periods and decreased from stimulation to extinction periods. In Expt II, 12 infants were given continuous social stimulation (elicitation treatment) for one period, and, in a second period, stimulation was withheld for 5 sec contingent upon each vocalization (omission treatment). Response rates were similar for both periods, and rates decreased when social stimulation was removed (mobile treatment). In both studies social stimulation increased vocalization rates and rate of responding was insensitive to the programmed contingency. There were, however, fewer “bursts” of responses with the negative and positive contingencies as compared with response-independent stimulation.     

Couples treatment of agoraphobia: changes in marital satisfaction

Six agoraphobic women and their husbands participated in a group therapy program consisting of exposure and cognitive restructuring. The husbands acted as co-therapists. Ratings of marital satisfaction as well as severity of phobia were filled out independently by both clients and their husbands throughout the course of therapy and at follow-up. Two patterns of relationships among marital satisfaction and severity of phobia emerged. For four couples a parallel relationship was observed in that as phobia improved marital satisfaction increased. For two couples the inverse relationship was noted where improvements in phobia were correlated with decreases in marital satisfaction. The importance of the interpersonal context of agoraphobia and implications for treatment are suggested.     

On the reciprocity of proximity relations

The degree of reciprocity of a proximity order is the proportion, P(1), of elements for which the closest neighbor relation is symmetric, and the R value of each element is its rank in the proximity order from its closest neighbor. Assuming a random sampling of points, we show that Euclidean n-spaces produce a very high degree of reciprocity, $\text{P(1) ≥}\text{1}\text{2}$, and correspondingly low R values, E(R) ≤ 2, for all n. The same bounds also apply to homogeneous graphs, in which the same number of edges meet at every node. Much less reciprocity and higher R values, however, can be attained in finite tree models and in the contrast model in which the “distance” between objects is a linear function of the numbers of their common and distinctive features.     

The effect of reinforcement for global or analytic strategies on the performance of reflective and impulsive children

Second and sixth grade impulsive and reflective children were administered a conceptual style task with a modification that children were reinforced specifically for either global or analytic processing. Results indicated that both reflectives and impulsives were capable of offering either a global or analytic hypothesis under appropriate reinforcement. Results were interpreted as indicating the relevance of motivational factors to reflection/impulsivity and cognitive style.     

Group differences in intelligence and speed of information-processing

Three samples of different levels of mental ability, but each of average or above- average intelligence, were administered a battery of reaction time test which measure the speed with which persons can execute various elementary cognitive processes. Discriminant analyses revealed significant differences between the groups in reaction times and intraindividual standard deviations, and univariate analyses indicated that higher ability groups tended to obtain significantly faster mean reaction times and to show significantly less intraindividual variability than lower ability groups. Groups which differed the most in mental ability differed to the greatest extent on the more complex reaction time tests but this pattern was reversed for groups which were relatively close in mean IQ. Generally, the results support the hypothesis that speed- of-processing is an important factor unferlying intelligence, but a number of puzzling findings indicate the need for continued research in this area.     

The degree of control exerted by phobic and non-phobic verbal stimuli over the recognition behaviour of phobic and non-phobic subjects

Four groups of subjects comprised of one control group, two analogue phobic groups and one clinical phobic group were exposed to a dichotic listening experiment in which they were required both to shadow one message to the exclusion of the other and recognize the occurrence of target words appearing in both the attended and rejected messages. Target words were either phobic-relevant or neutral. It was found that the clinical phobic group recognized significantly more target words than any of the other groups. This difference was due to their superior recognition of phobic-relevant targets from the rejected message. The results were interpreted within a combined framework of Staats's (1968, 1975) social behaviour theory and the Rescorla and Wagner (1972) model of classical conditioning.     

Motivation concepts and sexual identity

The association dimension of the Picture Identification Test (PIT) was used to investigate the motivation concepts of male and female university students classified as Declared Homosexual, Sexually Uncertain, Clinical Control, and Normal Control. The t test was used to identify Need Association Dyads which discriminated (p < .01) groups. Greater than chance numbers of variables discriminated each of the pairs of groups within each sex except the Sexually Uncertain versus Clinical Control Male groups, the Declared Homosexual versus Clinical Control Female groups, and the Declared Homosexual versus Normal Control Female groups. PIT Need Association Dyads were discussed as a type of implicit personality theory assessment with emphasis on the beliefs subjects hold about the simultaneous expression of needs.     

The acquisition of taste aversions in humans

A written questionnaire or an interview was given to 517 undergraduates concerning their acquisition of illness-induced (taste) aversions to foods and drinks. The subjects reported 415 aversions, with 65% of the subjects reporting at least one aversion. The aversions were more likely to be reported as having been formed through forward rather than simultaneous or backward conditioning, and long-delay learning was frequent. The aversions usually formed to the taste of the foods, rather than the appearance or other aspects of the foods. Extinction appeared more effective in decreasing the aversions than did forgetting. The illness responsible for the aversion's forming was usually attributed to the subsequently aversive food, but for 21% of the reported aversions subjects were sure that something else had caused their illness. Aversions were more likely to have formed to relatively less familiar and less preferred foods. Aversions were also more likely to form between the ages of 13 and 20. Generalization of the aversions to similar foods occurred in 29% of the cases. Approximately one fourth of the aversions were to alcoholic beverages. Finally, instances of aversions forming without food or drink consumption and instances of observational learning were reported. The data were quite similar to laboratory taste aversion data collected using other species and can help in optimizing taste aversion treatments of eating and drinking disorders. Taste aversions among humans are frequent and strong.     

Treating bruxism with the habit-reversal technique

The habit-reversal technique developed by Azrin and Nunn (1973, 1977) was used in treating four clients with bruxism. Following a single treatment session, marked reductions in the frequencies of this behavior were obtained in each case. Subsequently, relaxation and stress management techniques were conducted with two of these clients who had facial pain. These procedures were associated with decreased pain ratings and medications for one client and a further decrease in bruxism and cessation of pain for the second. These results remained consistent over 6- and 12-month follow-ups. Each of the components of habit-reversal appeared to be related to its effectiveness, and methods for performing component analyses of this technique are described.
