The present study was designed to evaluate the efficacy of utilizing an avoidance conditioning paradigm in EMG biofeedback training and to compare this method to the standard biofeedback training paradigm. Frontalis EMG levels of 20 college students were monitored during non-stress and stress conditions. Half then received standard EMG biofeedback training. The other half received biofeedback with contingent aversive stimulation. Both groups received training to a relaxation criterion of 3 microvolts for 100 seconds or, for a maximum of two 20 minute sessions. Subjects were then monitored again during non-stress and stress conditions. Both groups obtained significant EMG reductions due to training with no significant differences between them. Standard biofeedback training required less time for subjects to achieve the relaxation criterion than did biofeedback with a shock-avoidance contingency. Possible applications of avoidance contingent biofeedback were suggested.

That odors play a significant role in subhuman intraspecies communication is a generally accepted fact explained in part by the production and reception of species specific pheromones. Recently the effects of human produced odors on human communication have received research attention, particularly in the communication of such biological phenomena as menstruation onset and gender assignment. Again pheromones have been posited as the explanatory mechanism. Whether a pheromone-like odor cued process exists in the communication of human emotions is unknown, though a number of anecdotal accounts of odor-emotion interactions suggest that such may be the case. It was the purpose of the present study to investigate a possible odor-emotion interaction by determining whether humans could differentially detect other humans' odor collected under varying emotional conditions.

This investigation utilized a novel, self-help, multi-element psychological program to manage chronic low back pain. A literature review indicated that this disorder was costly and prevalent, yet a large percentage of chronic low back pain patients did not respond to traditional treatment. Recent research has demonstrated that numerous psychological difficulties have been associated with this disorder, including depression and anxiety. It was hypothesized that these psychological concomitants of chronic low back pain maintain and promote further pain, as part of a vicious cycle. Self-help treatment attempted to break this tension-pain-anxiety cycle using various stress reduction, and cognitive and behavioral management strategies.
