Cognitive and physiological indices of sexual arousal in homosexual,bisexual, and heterosexual males

Cognitive and physiological indices of sexual arousal were investigated utilizing groups of homosexual, bisexual, and heterosexual subjects (ten subjects per group) who were presented both homosexual and heterosexual films and slides. The results indicated that both homosexual and heterosexual subjects were able to estimate accurately their degree of erection to the erotic stimuli. Bisexual subjects, however, showed a large discrepancy between the magnitude of actual erection and verbally reported estimates of penile tumescence. In terms of physiological arousal, the erectile responses of the homosexual and bisexual groups were indistinguishable, a finding which questions the existence of male bisexuality as distinct from homosexuality or as a different sexual orientation in males.     

A critique and extension of Bronfenbrenner's Moral Dilemma Test

Critical reading of Bronfenbrenner's Moral Dilemmas Test (MDT) suggests that it measures two basic kinds of moral dimensions: (1) “Negative-passive” moral choices which require the child to resist peer pressure to violate conventional norms in situations fraught with potential adult sanctions, and (2) “Positive-active” moral choices which require performance of an act that affirms a moral principle and implies a benefit for recipients of the act. To test the validity of these distinctions, additional positive-active type dilemmas were constructed to balance the overemphasis on negative-passive situations found in the original MDT. This expanded MDT was then administered to samples of Mormon, Catholic and public school children. Responses from all samples were subjected to factor and cluster analyses and then to a “multitrait-multimethod matrix”. These analyses provide support for the need for making moral sub-distinctions by producing item clusters that are consistently based on the a priori defined negative-passive and positive-active dimensions. A third dimension is also discernable among certain of the original MDT items, but it represents an achievement orientation of only-secondary moral significance. Implications of these conceptual distinctions for linking different kinds of moral responses to different kinds of social contexts are discussed.     

Lump detection in simulated human breasts

Sixteen observers palpated silicone models of human breasts containing lumps 1.6-12.1 mm in diameter. Detectability depended on the size of the lump, producing a systematic psychometric function. In eight observers who participated in three or more sessions, performance improved with practice, with most improvement occurring within one or two 26-trial sessions. Three-week retention measures disclosed no appreciable decrease in performance, but a significant correlation was found between the number of lumps detected and duration of trial (p < .01). There was no difference in performance between four observers who used their preferred hands and four observers who used their nonpreferred hands. These data establish that examination of breast models for the detection of lumps simulating cancer is a task amenable to experimental analysis.     

Alcohol-induced changes in contrast sensitivity following high-intensity light exposure

Relatively low doses of alcohol produced large, significant, dose-related increases in the time required to recover foveal contrast sensitivity following bright light exposure. Nine subjects participated in a double-blind experiment involving three dose levels of alcohol (including placebo). The luminance parameters of the test were comparable to those encountered in practical situations such as driving. The alcohol-induced delay in glare recovery is probably retinal and lasts for several hours after drinking.
