Fear response to dissociation challenge

Abstract

Participants (N = 101) scoring high or low on a new scale for assessing fear of dissociative sensations (Dissociation Sensitivity Index) underwent an audio/visual sensory challenge using a device called the D.A.V.I.D. Participants' report of subjective fear and level of dissociation were measured before and after completing the audio/visual sensory challenge. Consistent with prediction, participants scoring high on the DSI responded to the challenge with significantly greater increases in subjective fear and dissociative symptoms relative to those scoring low on the DSI. Contrary to prediction, the DSI performed poorer than the Anxiety Sensitivity Index in predicting participants' response to the audio/visual sensory challenge. Theoretical and clinical implications of the findings are discussed.     

Arguing at Cross-Purposes: Discharging the Dialectical Obligations of the Coalescent Model of Argumentation

The paper addresses the manner in which the theory of Coalescent Argumentation [CA] has been received by the Argumentation Theory community. I begin (section 2) by providing a theoretical overview of the Coalescent model of argumentation as developed by Michael A. Gilbert (1997). I next engage the several objections that have been raised against CA (section 3). I contend that objectors to the Coalescent model are not properly sensitive to the theoretical consequences of the genuinely situated nature of argument. I conclude (section 4) by suggesting that the resolution to the dispute between Gilbert and his objectors hinges on the outcome of several foundational theoretical questions identified over the course of the paper.     

Empirical derivation of SVIB-Holland scales and conversion tables

Significant relationships between the Holland Vocational Preference Inventory (VPI) and the Strong Vocational Interest Blank (SVIB) were again empirically demonstrated in this study, and conversion equations were developed to use standard scores of SVIB scales, rather than items, to produce estimates of VPI scores. Cross validation on a limited population yielded supportive evidence that these conversion equations can provide meaningful VPI estimates from SVIB scale scores. The need for validation across a variety of populations was underscored in order to assess further generalizability of these findings.     

Dry-bed training: rapid elimination of childhood enuresis

Enuresis has been treated with moderate effectiveness by the urine-alarm method which requires many weeks of training. The present procedure used a urine-alarm apparatus but added such features as training in inhibiting urination, positive reinforcement for correct urinations, training in rapid awakening, increased fluid intake, increased social motivation to be nonenuretic, self-correction of accidents, and practice in toileting. After one all-night training session, the 24 enuretic children averaged only two bedwettings before achieving fourteen consecutive dry nights and had no major relapses. Little or no reduction in bedwetting occurred within the first two weeks for matched-control enuretics who were given the standard urine-alarm training. The results of a control-procedure showed that the new procedure did not involve Pavlovian conditioning. The new method appears to be a more rapid, effective and different type of treatment for enuresis.     

The restoration of extinguished avoidance responses

Following extensive signaled shuttlebox avoidance training, Fischer 344 rats were given extinction trials until they reliably stopped responding and, thereafter, they received occasional classical CS-UCS pairings during the course of restoration test trials in which shock was absent. Experiment I demonstrated that the classical contingency was both necessary and sufficient for the complete recovery of such behavior. Experiment II revealed that the degree of recovery was not differentially affected by the frequency of such CS-UCS pairings. However, in Experiment III recovery in the presence of this contingency was shown to depend on the number of previous extinction trials, although even after a large number of such trials, a considerable degree of recovery occurred. These findings demonstrated the central role of the classical CS-UCS contingency in restoring a previously extinguished avoidance response.     

Alcoholic drinking: suppression by a brief time-out procedure

Volunteer chronic alcoholics were given daily access to substantial quantities of alcohol within a residential research setting. Drinking was suppressed to an average of approximately one-half of Baseline levels when 10 or 15 min of physical and social isolation was required as an immediate consequence to receiving each one-ounce drink of 95-proof ethanol. This time-out procedure suppressed the drinking of nine out of ten subjects. Drinking returned to high levels when brief contingent time-out was discontinued. The relevance of such reversible controlling relationships to the treatment of alcoholism is discussed.     

A rapid method of eliminating stuttering by a regulated breathing approach

The Habit Reversal Procedure for eliminating nervous habits was applied to the problem of stuttering. In the new procedure the speaker interrupted his speech at moments of actual or anticipated stuttering and at natural pause points, and resumed speaking immediately after breathing deeply during the pause. In addition to this regularized pausing and breathing, the program included other factors such as formulation of one's thoughts prior to speaking, identification of stutter-prone situations, identification of mannerisms associated with stuttering, speaking for short durations when tense or nervous, daily breathing exercises, relaxation procedures for anxiety, immediate display of improved speaking, and enlisting family support for progress. Fourteen stutterers were given training in the program during a single counseling session of about two hours duration. The next day, the average number of stuttering episodes decreased by 94 per cent, by 97 per cent at the end of one month, and by 99 per cent during the extended follow-up. Each of the clients was improved by at least 93 per cent. The new procedure appears to be more rapid and effective than alternative procedures.
