Experimental comparison of outcomes in insight- and non-insight-oriented therapy groups.

Compared the effectiveness of (a) group therapy stressing interpretive procedures intended to bring about client insight, and (b) a form of group therapy experience encouraging client * client interaction without the intentional development of insight. A total of 24 male psychiatric inpatients (20 diagnosed schizophrenic) were randomly assigned to insight, interaction, insight-interaction, or control groups. Ss were given behavioral, psychometric, and self-rating measures (e.g., the MMPI) before and after treatment. Although there were no significant differences between experimental conditions on any of the outcome measures, the insight-interaction group showed the most consistent indications of improvement on the 21 measures assumed to assess "personal functioning." None of the other group comparisons were statistically significant. (16 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Experimental and ethical problems of evaluating the influence of hypnosis in antisocial conduct.

Attempted to improve the procedures of an earlier experiment concerning the ability of hypnosis to create antisocial behavior. The influences of a personal relationship between S and hypnotist, and of S's knowledge of participation in an experiment, were examined. A measure of an S's moral stance toward the specific antisocial act (selling heroin) was also obtained. Ss were 22 female and 4 male undergraduates in 4 groups. Results suggest that the experimental manipulations were generally successful in deceiving Ss into believing that the antisocial request was separate from an experiment, and that an S's moral stance toward the act may be an important variable in determining compliance with requests to engage in antisocial behavior. The major finding, however, is identification of methodological and ethical problems in research of this kind, and these are considered in some detail.

A generalization of the Schützenberger product of finite monoids

For each n?1, an n-ary product ? on finite monoids is constructed. This product has the following property: Let Σ be a finite alphabet and Σ¹ the free monoid generated by Σ. For i = 1, …,n, let A_i be a recognizable subset of Σ¹, M(A_i) the syntactic monoid of A_n and M(A₁?A_n) the syntactic monoid of the concatenation product A₁?A_n. Then M(A₁?A_n)< ? (M(A₁),…,M(A_n)). The case n = 2 was studied by Schützenberger. As an application of the generalized product, I prove the theorem of Brzozowski and Knast that the dot-depth hierarchy of star-free sets is infinite.     

Punishment of saccharin drinking by amphetamine in rats and its reversal by chlordiazepoxide.

Demonstrates, in a conditioned taste-aversion paradigm, that doses of dextroamphetamine which are intravenously self-administered by rats may punish saccharin drinking. Ss were male Wistar rats. In Exp I (n = 42), single-trial, dose-related aversion was shown. Aversion was not antagonized by chlorpromazine. Exp II (n = 32) demonstrated dose-related acquisition of taste aversion with repeated administration of very low amphetamine doses. In Exp III (n = 18), drug-induced saccharin aversion was reversed by chlordiazepoxide; this action paralleled the action of chlordiazepoxide in numerous other aversive-conditioning situations. Exp IV (n = 30) ruled out the possibility that depression of saccharin drinking was due to a direct pharmacological action of the drug and not to learned saccharin avoidance. Results indicate that the reinforcing action of amphetamine depends on the response with which its effects are correlated. (20 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Measuring oxygen permeabilities of polymer films by a new singlet oxygen technique

A new sensitive method is described for measuring the permeation and diffusion of oxygen through polymer films. For these measurements an ethyl cellulose film containing 9,10-dimethylanthracene (DMA) and erythrosin may be either tightly sealed between two pieces of sample film in a simple cell or sealed in a pouch made from the test material, and is used to absorb oxygen which has passed through the polymer film sample from the air. On illumination this oxygen is converted by the erythrosin to singlet oxygen which then reacts with the DMA. After an initial scavenging period, the rate of permeation of oxygen under the atmospheric pressure gradient across the film is monitored by determining the rate of disappearance of DMA spectrophotometrically.

Cuticular hydrocarbons of the eastern subterranean termite,Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae)

Major cuticular hydrocarbon components in several castes ofReticulitermes flavipes (Kollar) have been identified and quantitated. Types of hydrocarbons present includen-alkanes, 2-methylalkanes, 3-methylalkanes, 5-methylalkanes, an alkene, and an alkadiene, with a range in carbon numbers from C₂₁ to C₂₆, This is the first report on insect cuticular hydrocarbons in which both 2- and 3-methylalkanes are present, as well as the first report of an insect with a conjugated alkadiene.
