Changes in sexist attitudes toward women during introductory women's and men's studies courses

Sexism toward women scores of university students at the beginning of an introductory women's and men's studies (gender studies) course were compared with sexism levels of the same students at the end of the course and with sexism levels of controls. Differences in sexism levels associated with Bem's sex role categories were investigated. Sexism levels among students in every category, except undifferentiated, were significantly lower at the end of the course, while controls showed no pre/post differences. As expected, males were higher than females both at pretest and at posttest, and sexism in both sex groups decreased significantly by equivalent amounts; but androgynous males in the introductory course were lower in sexism than sex-typed males and androgynous females were lower than sex-typed females. Undifferentiated subjects decreased in sexism least during the course, and cross-typed and androgynous males decreased most. The relationship of sexism to several additional variables not included in formal hypotheses also is discussed. These variables were age, religion, ethnicity, SES, and grade earned in the gender studies course.     

Age and ability effects on test scores reflecting M-capacity, learning and cognitive style

Eight- and ten-year-old children of low and average ability were given four tests, one of which was developed by Pascual-Leone (1970) as a relatively pure measure of mental capacity (M-capacity) as conceived in his neo-Piagetian model. The remaining tests confounded knowledge base and cognitive style (field dependence/independence) with M-capacity to varying degrees. Age and ability effects were found, but were invariant over tests. This contradicts Globerson’s (1983) predictions for the hierarchy of tests used. Possible reasons for an apparent discrepancy between Globerson’s results and those of the present study are discussed.     

Aphasic performance on a lexical decision task: multiple meanings and word frequency

The lexical access of words varying in the number of meanings and frequency of occurrence was examined in fluent and nonfluent aphasic individuals and a control group of non-brain-damaged adults, using a lexical decision task. Fluent aphasic subjects performed similarly to nonfluent aphasic and normal subjects, showing that words with a high number of meanings and with a high frequency of occurrence were recognized as real words faster than words with few meanings or a low frequency of occurrence. While previous research has demonstrated that the number of meanings associated with a word exerts a powerful influence on the internal lexicon of normals, the results of this study suggest that brain damage resulting in aphasia does not disrupt this semantic organization.     

Speech event related potentials reflect linguistic content and processing level

Amplitude changes in the auditory event related response reflect differences in linguistic content and the level of processing of spoken sentences. Thus, the neurophysiology of the cognitive processes underlying speech perception can be evaluated by noninvasive techniques. Semantically correct, semantically incorrect, and grammatically incorrect sentences were processed either semantically or syntactically by 25 subjects while their EEGs were recorded. The amplitude of the P250 component to each word varied with processing level. A slow positive wave appeared after semantically correct sentences regardless of the linguistic processing level. N480 and P780 components were observed following words which made the sentences incorrect.     

Changes in imitative behavior during early infancy

Changes in imitative behavior and attentiveness were observed in 40 infants when they were 2 to 6 months of age. The facial expressions happy, sad, and surprised were modeled in a trials-to-criterion procedure, and the infants' looking time and mouth movements were recorded by an observer who was unaware of the face being modeled. In addition, the observer recorded her guess as to the expression being modeled by the corresponding expression on the infant's face and rated the infant's expressivity. The results suggested that looking time, correspondence between the mouth expression of the infant and the mouth expression modeled, accuracy of the observer's guess, and expressivity ratings decreased from 2 to 3 and 4 to 6 months. Although matching of mouth movements with the modeled mouth movements and accuracy of guesses were greater than chance over the 2 to 6 month-period, the decreases in these measures suggest that imitative behavior declined across early infancy. The decrease in looking time suggests that imitative behavior and attentiveness may be related and highlights the limitation of this paradigm for assessing the development of imitation during early infancy.     

Sex differences in dual-task interference between speaking and a manual force-production task

12 male and 12 female right-handed adults performed a unimanual force-production task alone and while sound-shadowing high frequency words. The secondary speech task disrupted right-hand performance by men and left-hand performance by women. The implications of these findings for intrahemisphere-interference models of dual-task performance are discussed.     

A measure of intensity of parental punishment

To test the possibilities that antecedents and consequents of certain levels of intensity of punishment may have far-reaching effects on behavior, a self-report measure of parental intensity of punishment was developed. Consisting of 33 different situations to which parents react, scores from the instrument were found to be reliable over time. Further construct validity was demonstrated with a variety of predicted relationships between punishment intensity and parent and child characteristics. Five samples of subjects were used with over 400 families, high intensity of punishment scores were found to be related to mothers' lack of warmth and to her intrusiveness when playing with her child; children's maladjusted behavior; aggression and impulsivity in boys; withdrawal and inhibition in girls, and uncooperativeness. Inconsistency of parental punishment also was associated with maladjustment. Results were discussed in terms of Rotter's social learning theory.     

Dimensions and determinants of judgements of colour samples and a simulated interior space by architects and non-architects.

Architects and non-architects made Semantic Differential ratings of colour samples (chips) and a simulated interior space (a model). In analyses of the total samples' ratings (architects and non-architects) of (a) colour chips and (b) models, and individual sample analyses, (c) architects' chip judgements, (d) architects' model judgements, (e) non-architects' chip judgements, and (f) non-architects' model judgements, five factors occurred, though not necessarily all in any one analysis. These were: (i) dynamism; (ii) spatial quality; (iii) emotional tone; (iv) evaluation; (v) complexity. Linear correlations between parameters of the Munsell Color System and the above factors in the various analyses were calculated, while parallel analyses were carried out employing a graphical technique described by Sivik (1974a) involving isosemantic maps. In all analyses, linear correlations between the colour parameters and judgements were found for the dynamism factor, spatial quality factor, and emotional tone factor. They were associated respectively with chroma, value, and hue. Inspection of the isosemantic maps indicated subsidiary effects of the non-dominant dimensions of a non-linear sort, though the maps also exhibited the linear relations. Linear correlations were low or non-existent for the evaluation and complexity factors, and the complex nature of their determinants was clear from the isosemantic maps. The dterminants of judgements were similar for architects and non-architects, with the exception of evaluative judgements for the models in which markedly different determinants were noted. Comparability of the present findings with other studies carried out in a variety of countries over a 20 year period was high for dynamism, spatial quality, and emotional tone, and it is suggested that there may be something inherent in the response to colour in relation to such judgements. Recent physiological work is discussed, and its limitations in terms of colours sampled and an overconcentration on the hue dimension noted. In contrast, it is suggested that dimensions of judgement, such as evaluation or complexity, reflect to a greater extent culture or training, and are hence independent of the basic colour attributes.     

Phonological encoding in the lexical decision task

In lexical decision experiments, subjects have difficulty in responding NO to non-words which are pronounced exactly like English words (e.g. BRANE). This does not necessarily imply that access to a lexical entry ever occurs via a phonological recoding of a visually-presented word. The phonological recoding procedure might be so slow that when the letter string presented is a word, access to its lexical entry via a visual representation is always achieved before phonological recoding is completed. If prelexical phonological recodings are produced by using grapheme-phoneme correspondence rules, such recodings can only occur for words which conform to these rules (regular words), since applications of the rules to words which do not conform to the rules (exception words) produce incorrect phonological representations. In two experiments, it was found that time to achieve lexical access (as measured by YES latency in a lexical decision task) was equivalent for regular words and exception words. It was concluded that access to lexical entries in lexical decision experiments of this sort does not proceed by sometimes or always phonologically recoding visually-presented words.     

Self-reinforcement: An assessment of external influences

Two experiments were carried out in which low- and high-demand characteristics of self-reward were assessed in a multiple-baseline design across subjects. In the first experiment, arithmetic performance of four children was systematically assessed under no-reinforcement, self-reward/low-demand and self-reward/high-demand phases. In the second experiment, the performance of four children on a less meaningful task was assessed under the same conditions employed in Experiment 1. Results indicated that performance rates were relatively stable during the no-reinforcement phase but that these rates dropped markedly during the self-reward/low-demand phase for all eight subjects. Further, increased rates of performance were achieved under the self-reward/high-demand phase for all subjects. Results are discussed in terms of the assessment of the self-reinforcement procedure, current definitions of self-reinforcement, and the need to view self-reinforcement as existing on a continuum of external demand characteristics.This project was supported in whole by a faculty research grant awarded to the first author and completed while the second author was a visiting associate professor at Western Psychiatric Institute and Clinic.
