Validity of the sex-role egalitarianism scale: Discriminating egalitarianism from feminism

To explore and to clarify the discriminant validity of the sex role egalitarianism construct, the Sex-Role Egalitarianism Scale (SRES) was administered in conjunction with the Attitudes Toward Women Scale (AWS) and eight personality trait measures to 108 individuals. Results indicated a hypothesized curvilinear relationship between scores on the SRES and the AWS. When personality traits were individually regressed on SRES and AWS, SRES scores uniquely accounted for variance in achievement locus of control, and AWS scores uniquely accounted for variance in need for autonomy and need for succorance. Findings were supportive of the viability of sex role egalitarianism as an attitudinal dimension having meaning beyond that of a traditional — feminist dimension.     

Effects of Expectancies and Personalized Feedback on Fat Consumption, Taste, and Preference

Previous studies have shown that people develop expectations about the taste and effects of consumed substances and that those expectations can guide future behavior, cognitions, and affect. Identifying expectancies for the taste of both low- and high-fat foods is important in determining people's reactions to changes in their diets. Study 1 was designed to determine the existence of expectancies for the taste of low-and high-fat foods and the effects of these expectations on food consumption and preference. Ninety-seven subjects tasted a bowl of ice cream and rated the taste on taste judgment forms. The fat content of the ice cream (high- versus low-fat) and the expectancy of high- versus low-fat content were independently manipulated using a balanced placebo design. Expectancy affected the consumption of ice cream under most circumstances: For women who received high-fat ice cream and for men, regardless of the ice cream received, consumption was higher when high-fat ice cream was expected than when low-fat ice cream was expected. Study 2 was designed to investigate the effects of educating individuals about the diet-cancer link on consumption and preference. Receiving information about diet and cancer, especially when the information was personalized, decreased overall consumption and reported preference. Current levels of daily fat consumption also affected laboratory consumption and preference. This study has several implications for interventions to lower dietary fat.     

Visual search for simple volumetric shapes

Five experiments measured reaction time (RT) to detect the presence or absence of a simple volumetric shape (target) dependent on the number of display items (distractors) and their depicted three-dimensional (3-D) orientation. Experiments 1–4 examined every pairwise combination of two different simple volumetric shapes in two 3-D orientations. Conditions exhibiting “pop-out” could be predicted by differences in their two-dimensional (2-D) features. Conditions in which search was slower support previously found search asymmetries for particular 2-D features. When the distractors were a mixture of the other shapes in the same 3-D orientation, search was serial, except when the target had a curved principal axis (Experiment 5). The results suggest that these simple volumetric shapes are not processed preattentively.     

Discrimination learning decreases perceived similarity according to an objective measure

Initial identification discriminations between two sizes and between two slants produced better overall performances on subsequent size and slant same-different discriminations, respectively. This size- and slant-specific transfer was due to an improvement on only the different pairs. Time-duration identification discriminations with the identical stimuli and response assignments improved neither overall same-different performances nor performances on different pairs. A good performance on different pairs relative to same pairs should indicate a low perceived similarity. The literature indicates that A-X and B-Y pairings produce a positive transfer on an A-versus-B discrimination when X and Y are relatively low in similarity, and also indicates that a low perceived (not physical) similarity improves discrimination learning. An increase in salience should have also improved performance on the same pairs. The conclusion: the initial discriminations decreased the perceived similarity of parts (size or slant). This decrease resembles perceptual contrast. A discrimination between two parts also seems to increase the extent to which each part is apprehended as a separate group. Therefore, the conclusion accords with the position that two groups are associated with contrast, including for visibility.     

Psychiatric sequelae of low birth weight at 6 years of age

The study examined the association between low birth weight (LBW) (2,500 g) and attention deficit hyperactivity disorder (ADHD) in two socioeconomically disparate populations. LBW and normal birth weight (NBW) children from the 1983 to 1985 newborn lists of an urban and a suburban hospital in Southeast Michigan were randomly selected. A total of 823 children, 473 LBW and 350 NBW, participated. Data were gathered in 1990 to 1992, when the children were 6 to 7 years of age. The National Institute of Mental Health Diagnostic Interview Schedule for children—Parent version (DISC-P) was used to elicit information on DSM-III-R diagnoses of simple phobia, overanxious, separation anxiety, oppositional defiant, and ADHD. Teachers' ratings of behavior problems were obtained. LBW was associated with ADHD but not with childhood anxiety disorders or oppositional defiant disorder. The association was stronger in the urban than in the suburban population. Data from teachers' ratings revealed an association between LBW and attention problems. The prognostic significance of the observed psychopathology at 6 years of age requires follow-up assessment as the children mature.This research was supported by NIMH research grant MH-44586 and NIMH Research Scientist Development Award MH-00380 to Dr. Breslau.

Letter identification and lateral masking in dyslexic and average readers

Lateral masking and letter identification in dyslexic and average readers were investigated with a methodology that corrected for some of the weaknesses of the Geiger and Lettvin studies (1986, 1987). Target letters were presented alone or embedded within three-letter arrays at retinal locations from 0 degrees to 15 degrees to the right or left of a fixation point. A foveal letter, which was the same as or different from a target letter, appeared as a distractor, and comparisons were made between scaled and unscaled stimuli. Dyslexic readers were found to be better than average readers at detecting scaled letters embedded in an array in some of the peripheral locations tested. Unlike the results of Geiger and Lettvin, however, this finding of better letter detection in the periphery by dyslexics was limited to selected conditions of the study. Reading groups were also found to differ in responding to the foveal distractor in the letter task. Detection of letters by average readers was affected by the type of distractor, but this variable was not found to influence the dyslexic readers. These findings suggest some differences between dyslexic and average readers in attention to stimuli presented at multiple locations in the visual field.     

Conflict over emotional expression: psychological and physical correlates

This study addresses the construct of conflict or ambivalence over emotional expression. Ambivalence is seen as an important mediator in the link between emotional styles and psychological and physical well-being. Using the "personal striving" framework, a questionnaire measure of ambivalent emotional strivings (AEQ) was designed. In Study 1, 292 Ss completed this measure along with questionnaire measures of expressiveness, social desirability, and intense ambivalence. Women scored significantly higher than men on both the AEQ and expressiveness. In Study 2, scores on the AEQ were found to be negatively correlated with self-reported and peer-rated expressiveness. In Study 3, 48 Ss participated in a 21-day study of mood and health. Expressiveness was positively correlated with some measures of well-being and with daily negative affect. Ambivalence was positively correlated with several indices of psychological distress. Although the AEQ correlated with questionnaire measures of physical symptomatology, neither the AEQ nor the expressiveness measures correlated with daily symptom reports. Results support the contention that conflict over emotional expressiveness is a variable worthy of study in its own right, having implications for research on personality and health.
