Joint factors in self-reports and ratings: Neuroticism,extraversion and openness to experience

Although most dimensional theories of personality assume that the same traits can be assessed in either ratings or self-reports, joint factor analyses of data from these two methods have seldom provided clear evidence in support of this position. Previous analyses have found a preponderance of within-method factors, or have had to transform variables or use unorthodox rotational procedures in order to control the effects of method variance. The present study argues that recent conceptual and technical advances should now make it possible to show joint factors at the second-order level using standard factor techniques. The NEO Inventory and NEO Rating Form, which measure 18 traits in the domains of Neuroticism, Extraversion and Openness to Experience, were administered to a sample of 281 men and women. Varimax rotation of three principal components clearly showed the hypothesized structure within and across self-reports and spouse ratings. Convergent and discriminant validity of the joint factors with the EPI scales was also shown. The results suggest that the effects of method variance can be minimized if well-qualified raters use psychometrically adequate instruments to provide ratings of clearly conceptualized traits. In addition, they provide strong evidence for the validity of the proposed three-domain model of personality.     

Covert sensitization, stimulus relevance and the equipotentiality premise

Covert sensitization and related cognitive aversive techniques have been widely used and reviewed but, to date, the issue of the quality and relevance of the aversive imagery selected has yet to be investigated. In the present study, Ss were given a target substance to consume and then presented with narratives designed to elicit either nausea, anxiety or relaxation. The nausea and anxiety scenes were rated as equally aversive but there was a significant reduction in consumption only within the taste-nausea imagery group. These results are consistent with those obtained from the study of taste aversion in infra-human Ss where taste has been shown to associate preferentially with nausea. The present results call into question the validity of the ‘equipotentiality premise’ in cognition. The implications of these findings for the clinical application and evaluation of covert sensitization are discussed.     

The influence of psychoticism and extraversion on classical eyelid conditioning using a paraorbital shock UCS

An experiment is described in which the effects of Psychoticism and Extraversion on classical eyelid conditioning were examined using a balanced design involving two levels of paraorbital shock intensity and two levels of response threshold. Questionnaire measures of Anxiety and Impulsivity were also analysed together with subjective ratings of the UCS. Results were broadly consistent with Eysenck's personality theory in that subjects scoring high on Psychoticism demonstrated lower levels of conditioning.     

Problems with stimulus/response equivalence and reactivity in the assessment and treatment of obsessive-compulsive neurosis

Self-recording was used as part of a comprehensive package of interventions to treat a case of obsessive-compulsive neurosis. The discrepancy between the self-recording data and other indices of improvement provoked consideration of the value of self-monitoring in light of Rachman's (1976) typology of obsessive-compulsives and the three major theoretical explanations of the reactivity of self-monitoring (Nelson and Hayes, 1981). It is hypothesized that self-monitoring may be countertherapeutic and misleading when there is stimulus/response equivalence or a checker type of obsessive-compulsive client.     

Behavioral training for myopia: generalization of effects

The present study assessed generalization of training effects using a video computer system (VCS) as a training medium for modifying acuity. Eighteen myopic volunteers were matched according to pre-training acuity and assigned to either fading and feedback training group or a practice only control. Subjects were pre- and post-tested on three measures: the Snellen Letter Chart, a Behavioral Acuity Test and a performance test with the VCS. Compared to controls, trained subjects displayed significant improvements in acuity on the Behavioral Acuity Test. These results suggest that training effects generalize to untrained stimuli. Implications for the clinical implementation of behavioral training procedures for modifying myopia are discussed.     

The effects of flooding on reducing snake fear in rhesus monkeys: 6-month follow-up and further flooding

Seven wild-reared rhesus monkeys were given two different 6-month follow-up tests to assess for spontaneous recovery of snake fear that had been somewhat reduced following 7 flooding sesions 6 months earlier. Both tests revealed essentially complete spontaneous recovery of fear. In addition, all 7 monkeys received 4 further mixed flooding sessions that involved exposure to real, toy and model snakes, and the 4 most fearful monkeys also received 3 more hours of exposure to the real snake alone. A final behavioral test following these additional flooding sessions revealed a pattern of changes very similar to that observed after the original 7 sessions 6 months earlier. In particular, there were some significant changes in the behavioral avoidance component of the fear but no changes in the behavioral disturbance component of the fear. The results are discussed in the context of earlier studies that purported to demonstrate that snake fear is easy to abolish. It is concluded that these earlier studies erred by not having tests for spontaneous recovery and by only testing for changes in the behavioral avoidance component of fear. Possible reasons for the failure to produce significant changes in the behavioral disturbance component of fear are discussed.     

The influence of introversion-extraversion on activity choice and satisfaction among the elderly

The present study investigated the optimum theory of aging. This theory predicts that individuals with different personality types will react differentially to the aging process. In the present study, 60 nursing-home residents were administered the Eysenck Personality Inventory and then randomly assigned to one of two experimental manipulations. Elderly subjects classified as extraverts showed a high level of satisfaction to an experimental manipulation which was of a high activity, interpersonal type; those classified as introverts evidenced more satisfaction with a low activity, non-interpersonal type manipulation. Inspection of records documenting actual participation in programs within the nursing home indicated that introverts were more often involved in low activity, non-interpersonal events whereas extraverts participated more often in high activity, interpersonal events. Implications of these results are discussed in relation to the optimum theory of aging.     

The reduction of anxiety in children: a comparison of the effects of 'systematic desensitization in vitro' and 'systematic desensitization in vivo'

Twenty-four children between the ages of 5 and 10. selected on the basis of fear of water, as determined by parents and swimming teachers, were divided into two experimental groups and one control group. One of the experimental groups was treated with four sessions of in vitro desensitization (gradual imaginal exposure to fear evoking stimuli plus relaxation), followed by four sessions of in vivo desensitization (real-life exposure to fear evoking stimuli plus relaxation). The other group received eight sessions of in vivo desensitization. The control group took part only in the tests, which were administered at the commencement of treatment, after four sessions, and at the end of the course of treatments. In testing, a behavior observation record was used to score the subject's behavior in the given situation; in addition, two teacher's records were used, in which swimming teachers recorded their evaluation of the subject's anxiety in each situation.Better results were achieved by desensitization in vivo than by desensitizalion in vitro or by the control procedure. No differences were found between the latter two groups. It could not be demonstrated that desensitization in vitro increased the effectiveness of subsequent desensitization in vivo     

Assertion modeling and stimuli effects on assertive behavior and self-efficacy in adolescents

The present investigation examined variations of modeling and stimuli with 61 adolescents selected for unassertive or aggressive behavior toward teachers. A 3 × 2 × 2 factorial design evaluated the effects of type of assertion modeling (three sessions of overt vs covert vs no-modeling), type of training stimuli (single involving teachers only vs multiple involving teachers, parents and peers) and type of initial behavior (unassertive vs aggressive) on behavioral role-play and self-efficacy. Modeling, particularly overt modeling, improved assertive behavior in teacher situations, peer situations and total teacher, parent, and peer situations. The use of single type stimuli improved self-efficacy in total teacher, parent and peer situations, and in novel situations involving others. Behavior but not self-efficacy was differentially affected by initial unassertive or aggressive behavior of participants. Self-efficacy and behavior were only moderately correlated. Results suggest effectiveness of short-term modeling with adolescents and different specificity properties of self-efficacy and assertive behavior.     

Assessment of social anxiety: a controlled comparison among social phobics,obsessive-compulsives,agoraphobics, sexual disorders and simple phobies

The construct validity of the Willoughby Personality Schedule (WPS) as an index of social anxiety was established in the present study. The WPS correctly identifies social phobics from controls in 88% of the cases.     

The effects of control and lack of control on active and passive avoidance in rhesus monkeys

Most studies which have examined the effects of lack of control have utilized test tasks in which active responding is required, and generally they have found impaired learning. Those few studies which have required passive responding in the test task generally have found facilitation of learning. The present two experiments examined the effects of lack of control in both active and passive avoidance tasks in a primate species (Macaco mulatta) not previously used in this research area. In Experiment 1, although the group without control (IE) tended to be inferior at active and superior at passive avoidance in comparison to the group with control (E), there were no significant differences. In Experiment 2, utilizing a difficult discrimination task in which subjects were required to learn when and when not to respond actively to avoid aversive stimulation, greater group differences were found. Two monkeys from Group IE failed to escape in active avoidance acquisition and, as a whole. Group IE was somewhat slower to respond than Group E. At passive avoidance, however. Group IE was superior to Group E and, as a consequence, more efficiently solved the discrimination problem. Implications of the present results for interpretation of the effects of lack of control as deficits are discussed.     

Individual response patterns and the effects of different behavioral methods in the treatment of agoraphobia

The importance of individual response patterns in agoraphobic patients was examined in the present study. Forty psychiatric outpatients with agoraphobia were assessed in individually relevant natural phobic situations. During this behavioral test their heart rates were measured continuously, and self-ratings of experienced anxiety were made at fixed intervals. On the basis of their reactions in the test situation, the patients were divided into two groups showing different response patterns—behavioral and physiological reactors. Within each group the patients were randomly assigned to one behaviorally-focused method (exposure in vivo, E) and one physiologically-focused method (applied relaxation, AR). The patients were treated individually for 12 sessions. Both treatments yielded significant improvements on most measures; 60% of the E group and 70% of the AR group patients were clinically improved after treatment. The between-group comparisons showed that both treatments did equally well both for behavioral and physiological reactors. Thus, the differential effects for these methods obtained in previous studies were not seen.     

The good,the bad and the mad: Response bias in self-report measures

This study set out to examine the susceptibility of five extensively used, self-report measures to response set bias. Subjects were requested either to fake good, (give a good impression), fake bad, (give a bad impression), fake mad, (give an impression of mental instability) or respond honestly. Subjects who faked good had significantly higher Extraversion, Lie and Social Desirability scores but lowest Neuroticism, Psychoticism and Social Anxiety scores. Subjects who faked bad had significantly lower Extraversion and higher Psychoticism and Social Anxiety scores. Fake mad subjects scored higher on Self-Monitoring and Locus of Control. Four of the eight scales showed significant differences between subjects faking bad and those faking mad. The results are discussed in terms of questionnaire design and respondent's motivation.     

Generalization of treatment effects in training public speakers

Three studies compared the efficacy of various treatments for public-speaking incompetence. These effects were evaluated for the target behavior as well as for generalization effects across situations (conversations), settings (different sizes and types of audiences) and time (6-month follow-up). The first study showed that Self-instructional Training, either alone or in combination with other procedures, produced little or no benefits. The second study demonstrated the superiority of a Skills Training program over flooding therapy, while the final study failed to detect any enhancement of treatment benefits for the addition of home-practice to the Skills Training. In the first two studies generalization occurred across the three dimensions (settings, situations and time), while in the final study it was shown that the program was effective for a clinical population as well as recruited volunteers.     

Depression,restraint and eating behavior

Contrary to the belief that weight loss is a principal symptom of depression, several recent studies have suggested that certain people gain rather than lose weight when depressed. The present experiment concerned the effects of experimentally induced mood states on the eating behavior of high- and low-restraint persons. Sixty-eight female undergraduates were randomly assigned to one of three groups each designed to induce a different mood state (depressed, neutral or elated), and were classified as high or low restraint based on their responses to a questionnaire. During the mood induction procedure subjects were provided with the opportunity to eat. High-restraint persons induced into a depressed mood ate significantly more than high-restraint persons induced into neutral or elated moods, and more than low-restraint persons induced into a depressed mood. This effect was most prominent among subjects who scored high on the weight-fluctuation factor of the restraint scale. There was no evidence that this effect occurred among subjects who scored high on the concern for dieting factor. The role of emotional arousal on the self-control over eating behavior of high weight-fluctuation persons, and the implications of these findings for the evaluation of depression were discussed.     

Factor structure of the Menstrual Symptom Questionnaire: relationship to oral contraceptives, neuroticism and life stress

The Menstrual Symptom Questionnaire was administered to initial and cross-validation samples of college-age women. Factor analyses performed on the data from each sample failed to support Dalton's distinction between spasmodic and congestive forms of primary dysmenorrhea. Instead, a more complicated factor structure evolved, closely resembling Webster's findings, with factors representing menstrual pain, pre-menstrual negative affect, pre-menstrual water retention, pre-menstrual pain, menstrual backache and menstrual gastrointestinal symptoms. Oral contraceptive use was negatively related to menstrual pain and backache. Neuroticism scores were positively related to all six factors, and negative life changes to four of these factors, suggesting a role for psychogenic factors in both pre-menstrual and menstrual symptomatology.     

Interrogative suggestibility,delayed memory and self-concept

This study investigates the relationship between interrogative suggestibility as measured by the Gudjonsson Suggestibility Scale (GSS) and variables related to memory recall and self-esteem. There were 30 Ss, tested twice 1 week apart. After completing the GSS they were required to fill in a number of Semantic Differential scales relating to the concepts: Myself as I am generally, Myself during the experiment and The experimenter. Ss were generally more suggestible during the second interview when their memory about the context of the interrogation context had deteriorated. The exception was that negative feedback appeared to have most effect on suggestibility and self-esteem the first time it was applied. Self-esteem related to ‘competence’ and ‘potency’ correlated significantly with suggestibility, especially during the first interrogative session. Perceptions of the experimenter were generally not found to be significantly related to suggestibility.     

Personality,dream content and dream coping style

One hundred and thirty Ss completed the Eysenck Personality Questionnaire and a Dream Analysis Questionnaire (DAQ), based on retrospective recall. Differential dream content was self-rated on three parameters: frequency, duration and intensity. Factor analyses identified three specific dimensions of dreaming: ‘Personal Avoidance’, ‘Eroticism’ and ‘Adventuresomeness’. It was clear that, on the frequency and image-intensity categories, dream content related overwhelmingly to Neuroticism. Personality , as measured, was clearly related to the salience (e.g. clarity of imagery, emotionality) of dreams. Given the specificity of dream content, the results suggest the presence of a person-specific coping style, primarily affective in nature. The findings are discussed in light of the continuum or parallel model of the dream-waking cycle. Implications for the cognitive modification of aberrant dream images or fantasy processes are briefly reviewed.     

Field dependence,sensation seeking and driving behaviour

The present study attempted to relate field dependence-independence (FDI) to accident involvement and perceived causes of accidents as well as to trace these relationships to the sensation-seeking (SS) tendency of the field-dependent driver. In addition, the concomittant effects of internal/external locus of control (IE) were studied. Subjects (N=285) filled out a questionnaire assessing their level of FDI, SS, IE, number of accidents, as well as the attributed importance of various possible causes of their last accident. The obtained results show no relationship between FDI and SS and either the number of accidents or the importance attributed to various causes of accidents. Significant relationships were, however, obtained between FDI and SS and seat-belt use and SS and speed on the highway.     

Factors in the referral of children for behavioral treatment: A comparison of mothers of clinic-referred deviant,clinic-referred non-deviant and non-c

The purpose of this study was to compare a non-clinic sample of mothers and children to two groups of clinic-referred children and their mothers. The two clinic-referred groups differed from one another in that the selection criterion for one group of children (Clinic Deviant) was that they were significantly more deviant and non-compliant than the non-clinic group whereas the selection criterion for the second group of children (Clinic Non-deviant) was that they did not differ significantly from the non-clinic group on deviant and non-compliant behavior. Home observations by independent observers and parent questionnaires examining parental adjustment and parental perceptions of child adjustment were completed. The results indicated that both clinic groups perceived their children as more maladjusted than parents in the non-clinic groups perceived their children. Parents of the children in the Clinic Non-deviant group were significantly more depressed than those in the remaining two groups, whereas parents in the Clinic Deviant group issued more vague, interrupted commands than those in the Clinic Non-deviant group. Implications of the findings are discussed.
