Memory for humorous cartoons

Incidental memory for three types of cartoons was compared: original cartoons, literal translations of the originals, and weird cartoons created by inserting incongruous material into the literal translations. In Experiment 1, the three types of cartoons were mixed together in lists. In Experiment 2, each list contained only two cartoon types. In both experiments, original cartoons were remembered better than the literal and the weird cartoons, whereas the literal and the weird cartoons were equally well remembered. The detection of incongruities, or attempts to resolve those incongruities, cannot adequately explain the observed humor effects. The results were also inconsistent with both rehearsal and distinctiveness interpretations. Rather, humor per se appears to support good memory performance. Perhaps participants elaborated or gave sustained attention to humorous material at the expense of less humorous material.     

Anxiety and depression as correlates of self-reported behavioural inhibition in normal adolescents

In a previous study, Muris, Merckelbach, Wessel, and Van de Ven [Psychopathological correlates of self-reported behavioural inhibition in normal children. Behav. Res. Ther. 37 (1999) 575-584] found that children who defined themselves as high on behavioural inhibition displayed elevated levels of psychopathological symptoms compared to children who defined themselves as low or middle on behavioural inhibition. The present study further examined the relationship between self-reported behavioural inhibition and anxiety disorders and depression symptoms in a large sample of adolescents aged 12-18 years (N=968). Adolescents completed a measure of behavioural inhibition and questionnaires of anxiety and depression. Results indicated that adolescents who classified themselves as high on behavioural inhibition had higher scores of anxiety and depression than adolescents who classified themselves as low or middle on behavioural inhibition. Structural equations modelling was employed to test hypothetical models on the role of behavioural inhibition in childhood anxiety and depression. It was found that a pathway in which behavioural inhibition results in anxiety, which in turn leads to depression, provided the best fit for the data.     

Anxiety sensitivity in adolescents: factor structure and relationships to trait anxiety and symptoms of anxiety disorders and depression

The current study examined the anxiety sensitivity construct in a large sample of normal Dutch adolescents aged 13-16 years (n=819). Children completed the Childhood Anxiety Sensitivity Index (CASI; Silverman, W. K., Fleisig, W., Rabian, B. & Peterson, R. A. (1991). Journal of Clinical Child Psychology, 20, 162-168) and measures of trait anxiety, anxiety disorder symptoms and depression. Results showed that (1) anxiety sensitivity as indexed by the CASI seems to be a hierarchically organized construct with one higher-order factor (i.e., anxiety sensitivity) and three or four lower-order factors, (2) anxiety sensitivity and trait anxiety were strongly correlated, (3) anxiety sensitivity was substantially connected to symptoms of anxiety disorders (in particular of panic disorder and agoraphobia) and depression, and (4) anxiety sensitivity and trait anxiety both accounted for unique proportions of the variance in anxiety disorder symptoms. Altogether these findings are in agreement with those of previous research in adult and child populations, and further support the notion that anxiety sensitivity should be viewed as an unique factor of anxiety vulnerability.     

Prospective evaluation of the etiology of anxiety sensitivity: test of a scar model

A large body of research has suggested that anxiety sensitivity (AS) acts as a specific vulnerability factor in the development of anxiety pathology. More recently, attention has turned to the etiology of AS per se. The present study represents a specific test of a Scar model of AS. A Scar model posits that the experience of distress will affect the vulnerability factor. We were specifically interested in evaluating the effects of a specific stressor (spontaneous panic) as well as general distress on changes in AS over time. A large nonclinical sample of young adults (N = 1296) was prospectively followed over a five week highly stressful period of time (i.e. military basic training). Findings were consistent with the Scar model and suggested that the specific stressor of experiencing a panic attack as well as general stressors creating significant anxiety symptoms uniquely contributed to increased levels of AS (regardless of prior history of panic). Moreover, the experience of spontaneous panic in the context of generally low levels of distress (both anxiety and depression) appeared to be particularly pernicious in terms of resulting in greater increases in AS. In sum, anxiety-related stressors appear to have the potential to 'scar' individuals in regard to this cognitive vulnerability factor.     

Endogenous attention and illusory line motion reexamined

P. Downing and A. Treisman's (1997) failure to replicate an effect of endogenous attention on the direction of illusory line motion (ILM) was reexamined. Four experiments with slightly modified stimulus presentation methods based on gradient theories of ILM found that endogenous attention directed to 1 of 2 similar priming objects is capable of influencing experienced motion direction within a subsequently presented line. The endogenous effect on ILM was consistent with a concomitant response-time discrimination task, was robust across naive and informed participants, occurred whether eye fixation was monitored or not, and occurred under conditions where multiple motion response categories were available to participants. The endogenous effect disappeared when participants moved their eyes to the attended item, when there was no motivation to endogenously attend, and when the presentation methods of P. Downing and A. Treisman (1997) were used.     

Therapeutic failure in a case of aversion therapy

A problem of paramount importance in the application of behaviour therapy concerns the relationship between personality parameters and the therapeutic outcome of such therapy, particularly in the case of aversion therapy. This report is concerned with a comparison between two patients with similar psychometric scores and similar complaints, one of whom responded well to aversion therapy while the other withdrew from treatment. It is argued that this differential response to treatment was due not to the amount of anxiety present but rather to a specific fear in the case of the latter patient that the treatment itself would precipitate cancer. Precautionary enquiries along these lines should, in future, be carried out prior to embarking on an aversion therapy programme.     

A comparison of positive and negative (aversive) conditioning in the treatment of homosexuality

A variety of techniques based upon learning theory were applied in the treatment of a male homosexual patient. The experimental results point to the overwhelming importance of aversive techniques for the treatment of this condition when compared with non-aversive techniques. The discussion draws attention to the inappropriateness of the medical concepts of cure and relapse in behavioural manipulations involved in behaviour therapy.
