Models of word recognition

Major hypotheses about the processes involved in word recognition are reviewed and then assessed through four experiments. The purpose of the first experiment was to examine some basic aspects of the processing of words, pseudowords, and nonwords, and beyond that, to discover basic differences in their processing that might underlie the word advantage. The second experiment was designed to assess the contribution of whole-word and letter cluster cues to the word advantage. Finally, Experiments III and IV were focused on the question of whether the word advantage can be wholly explained in terms of response bias or sophisticated guessing. Taken together, the results of these experiments were most compatible with criterion bias models. A version of the criterion bias model is suggested wherein the word advantage is attributed to interfacilitation among single letter and lexical units in memory.     

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.     

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.

Assessment of mothers' concerns about infants,toddlers, and preschoolers

Only recently has determining the child-rearing concerns of parents been considered an important research objective. Existing efforts have, for the most part, either employed small sample sizes or surveyed parents already in the process of seeking help or advice. It was, therefore, felt that additional, more representative data were needed. In the present study, 583 mothers with children aged 59 months or younger were surveyed regarding their concerns about their children's development. On the „Specific Needs Assessment Report”︁ (SNAR) (copyright © 1975, by Karl F. Riem, J. Jeffrey Crisco, and Kathy Willms), mothers rated their concerns for 60 developmental-behavioral items about their children's health, attending skills, problem behaviors, communication skills, motor skills, cognitive skills, self-help skills, and social skills. Mothers were most frequently concerned to a moderate or major degree about at least one item of the problem behavior category. For this category, parent-child management, crying-whining, and temper tantrums were the individual items of greatest concern. Mothers of girls more frequently indicated health concerns than mothers of boys. These results support those of previous investigations, which suggested the need for parent education programs to help parents manage their children.
