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.     

Temporal contiguity in electric aversion therapy for cigarette smoking

Seventy dependent heavy smokers (32 cigarettes per day) were randomly assigned to one of five treatment and control procedures: (1) electric aversion therapy, involving ten 20-trial sessions of shocks contiguous with the smoking act. (2) simulated electric aversion. with non-contiguous shocks, (3) non-shock smoking sessions, to control for stimulus satiation and negative practice effects. (4) simple support and attention from therapist, (5) no-treatment. Before treatment, simple ‘self-monitoring’ and ‘self-control’ reduced cigarette consumption by an average of 12% (p < 0.001) and 26% (p < 0.001) respectively. Thirty-four of the 56 treated subjects (61%) were able to stop smoking compared with two out of fourteen (14%) of the no-treatment controls (p < 0.005). Treatment was highly effective at reducing and stopping smoking during the 4-week course and for 2 weeks afterwards (p < 0.005). Its effect was rapid, but not immediate. Outcome was virtually decided after 1 week (five sessions); subjects who had not stopped or almost stopped at this stage were most unlikely to respond later on (p < 0.001). All four treatments were equally effective, regular attendance for 15 min of simple support being as effective as the treatments involving additional 45-min sessions with a second therapist. The effects of contiguous vs non-contiguous shocks did not differ. A motor response was conditioned in 19 of the 28 subjects who received shocks but this was therapeutically irrelevant. The clinical outcome depended on the kind of subject rather than the kind of treatment. Those who were depressed, with poor psychiatric adjustment and a high Eysenck-Scale P score tended to do badly, while those who initially expressed high confidence in the outcome were more likely to succeed (p < 0.001). It is concluded that traditional conditioning processes do not contribute significantly to the clinical response of human subjects to electric aversion therapy for cigarette smoking.     

Experiencing Alien-Nation: Effects of a simulation intervention on attitudes toward homosexuals

The authors explored psychological mechanisms underlying a teaching exercise [Hillman, J., & Martin, R. A. (2002). Lessons about gay and lesbian lives: A spaceship exercise. Teaching of Psychology, 29, 308-311] that may improve attitudes toward homosexuals. Heterosexual participants were randomly assigned to a simulation intervention or control lecture condition. In the simulation condition, participants imagined life on an alien planet that inadvertently simulated situational constraints parallel to those faced by homosexuals. The simulation (vs. control lecture) produced significantly more intergroup perspective-taking, empathy, and favorable attitudes toward homosexuals and marginalized groups. Tests of a structural equation model supported the assumption that the simulation (vs. control) provided an experience that heightened intergroup perspective-taking, which indirectly predicted favorable attitudes via independent cognitive (inclusive intergroup representations) and affective (empathy) paths. The model held after statistically controlling for prior attitudes and ideological individual differences predicting anti-homosexual bias. Implications for prejudice-reduction simulations and intergroup contact are considered.     

A preliminary report on a new auditory after-effect

It is found that protracted monotic stimulation at a certain frequency lowers the DL of that frequency for the contralateral ear by some 47 per cent. There were eight subjects and six controls; the frequency was 1,000 c.p.s. at 40 d.b.s. It is suggested that this after-effect is analogous to figural after-effects in vision. (Some further related findings, as yet preliminary, are also reported).
