Rational-emotive behavior therapy and the formation of stimulus equivalence classes.

Stimulus equivalence is a behavioral approach to analyzing the "meaning" of stimulus sets and has an implication for clinical psychology. The formation of three-member (A --> B --> C) stimulus equivalence classes was used to investigate the effects of three different sets of sample and comparison stimuli on emergent behavior. The three stimulus sets were composed of Rational-Emotive Behavior Therapy (REBT)-related words, non-REBT emotionally charged words, and a third category of neutral words composed of flower labels. Sixty-two women and men participated in a modified matching-to-sample experiment. Using a mixed cross-over design, and controlling for serial order effects, participants received conditional training and emergent relationship training in the three stimulus set conditions. Results revealed a significant interaction between the formation of stimulus equivalence classes and stimulus meaning, indicating consistently biased responding in favor of reaching criterion responding more slowly for REBT-related and non-REBT emotionally charged words. Results were examined in the context of an analysis of the importance of stimulus meaning on behavior and the relation of stimulus meaning to behavioral and cognitive theories, with special appraisal given to the influence of fear-related discriminative stimuli on behavior.

EMOSS: an epiillumination microscope objective slit-scan flow system.

An epiillumination microscope objective slit-scan flow system has been fabricated utilizing two dimensional slit scanning with hydrodynamic sample stream focussing. Low resolution (4 micron) analysis of cellular fluorescence is facilitated by the definition of a stabilized flow plane through hydrodynamic focussing. Coincidence of the region of stabilized flow with the focal plane of the microscope objective will allow for the collection and subsequent imaging of fluorescence from cells oriented along this plane. Two orthogonal slit-scan contours are generated as a cell traverses the excitation region. It is hoped that the need for a three dimensional system will be precluded by preferential orientation of the cells in the region of stabilized flow. Cellular fluorescence is collected by a high numerical aperture epiillumination optical system and imaged onto two orthogonal slits. Two photomultiplier tubes are used to detect fluorescence. It is anticipated that the epiillumination microscope objective slit-scan flow system will be used with a variety of fluorescent stains and markers, as well as extended to the research of light scattered by cells.

Gender differences in the sexual rating of words.

The present study investigated whether gender-based differences in the rating of sexual words still exist in the late 1990s. Men and women evaluated 400 English-language words on the characteristics of sexual charge and sexual ambiguity. Data gathered from these ratings were compared with other factors such as religious involvement, sexual experience, sex guilt, and social desirability. Men and women did not differ in their sexual ratings of the list. However, because the list contained a large number of words that had no sexual content at all, gender differences were examined for ratings of a sample of 30 sexually ambiguous words. As hypothesized, men rated these words as significantly more sexual than women. Significant gender differences were found on a number of sexuality and personality measures. Women were more religious than men, and religiosity was significantly correlated with most of the other measures. Women also had higher social desirability scores, which implies that they may have been responding in a socially desirable manner and were not completely honest. Overall, gender differences followed gender-oriented stereotypes: (a) Women have greater sexual guilt than men, (b) women are less sexually arousable or more "erotophobic," and (c) women are less comfortable answering questions about their sexuality and rating words.
