Effectiveness of biofeedback and relaxation training in reducing the side effects of cancer chemotherapy.

Assessed the effectiveness of electromyographic (EMG) and skin-temperature (ST) biofeedback and relaxation training (RT) in reducing the aversiveness of cancer chemotherapy. Eighty-one cancer patients, equated on several individual-difference variables, were randomized to one of six groups formed by a 3 (EMG Biofeedback, ST Biofeedback, No Biofeedback) x 2 (RT, No RT) factorial design. Outcome was assessed with physiological, patient-reported, and nurse-reported indices taken over five consecutive chemotherapy treatments. RT patients showed decreases in nausea and anxiety during chemotherapy and physiological arousal after chemotherapy. EMG and ST biofeedback reduced some indices of physiological arousal but had no other effects on chemotherapy side effects. These findings suggest that RT can be effective in reducing the adverse consequences of chemotherapy and that the positive effects found for biofeedback in prior research were due to the RT that was given with the biofeedback, not to the biofeedback alone.     

Activity, Passivity, Self-Denigration, and Self-Promotion: Toward an Interactionist Model of Interpersonal Dependency

ABSTRACT Although dependency in adults is inextricably linked with passivity and submissiveness in the minds of many theoreticians, clinicians, and researchers, evidence has accumulated which suggests that in certain situations, dependency is actually associated with high levels of activity and assertiveness. Three experiments were conducted to test the hypothesis that when a dependent person is concerned primarily with getting along with a peer, he or she will “self-denigrate” (i.e., will utilize strategies that ensure that a peer will be evaluated more positively than he or she is on a laboratory task), but when a dependent person is concerned primarily with pleasing an authority figure, he or she will “self-promote” (i.e., will adopt strategies that increase the likelihood that he or she will be evaluated more positively than a peer on a laboratory task). This hypothesis was supported in all three experiments. Theoretical implications of these findings are discussed, and an interactionist model of interpersonal dependency is briefly described.     

Battered women in the criminal justice system: An analysis of gender stereotypes

Battered women charged with killing their abusers present a dilemma to the criminal justice system. Myths and stereo-types about women and battered women play a prominent role in the courtroom presentation of both defense and prosecution cases. While the prosecution may attempt to discredit the defendant for not living up to the standard of a ‘good woman’, the defense counters with an equally distorted portrayal of the defendant as ultra-feminine: the passive, helpless victim. Ten court cases of battered women charged with the death of their partners form the basis for a gender analysis of the social construction of the trial setting. This analysis includes the structure of the trial, the language of the trial interchange, the participants in the process, and the role the defendant played in her own defense.     

Spatial limits to the detection of transpositional symmetry in dynamic dot textures

If a set of random dots is translated along a uniform axis and superimposed on itself, then the resulting texture is seen to have three possible perceptual outcomes depending on the degree of translation: pairedness, striation, and randomness. Similar perceptual effects are obtained by plotting identical point-pairs randomly in space and uniformly over time. The threshold between striation and randomness in dynamic dot textures was investigated, since it represents a spatial limit to the detection of transpositional symmetry. This limit was found to vary as a function of three factors: stimulus field diameter, retinal eccentricity, and high frequency attenuation. The limit was found to be invariant over a fourfold range of texture density. It is proposed that the ability of the human visual system to detect correlations in dynamic transpositionally symmetric textures is the result of the activation of populations of orientationally selective cells identified in the mammalian visual cortex. It is also proposed that the limits to this ability could be related to the average size of the receptive fields of such cells within a given region of the retina.     

Identification of vowels in “vowelless” syllables

Traditionally, it has been held that the primary information for vowel identification is provided by formant frequencies in the quasi-steady-state portion of the spoken syllable. Recent search has advanced an alternative view that emphasizes the role of temporal factors and dynamic (time-varying) spectral information in determining the perception of vowels. Nine vowels spoken in /b/ + vowel + /b/ syllables were recorded. The syllables were modified electronically in several ways to suppress various sources of spectral and durational information. Two vowel-perception experiments were performed, testing subjects’ ability to identify vowels in these modified syllables. Results of both experiments revealed the importance of dynamic spectral information at syllable onset and offset (in its proper temporal relation) in permitting vowel identification. On the other hand, steady-state spectral information, deprived of its durational variation, was a poor basis for identification. Results constitute a challenge to traditional accounts of vowel perception and point toward important sources of dynamic information.
