Encoding, repetition, and the mirror effect in recognition memory: Symmetry in motion

Attention/likelihood theory has been used to explain the mirror effect in recognition memory. The theory also predicts that any manipulation that affects the recognition of old items will also affect recognition of the new items—more specifically, that all the underlying distributions will move and that they will move symmetrically on the decision axis. In five experiments, we tested this prediction. The first two experiments used encoding tasks during study to change recognition performance for high- and low-frequency words. The results show symmetrical dispersion of the underlying distributions. The final three experiments used repetition to increase recognition performance. Repetition produced a symmetrical pattern of movement that was different from that produced by encoding task. This pattern is, however, also covered by attention/likelihood theory. A further extension of the theory was used to predict response times.     

Compensation for Jaw Fixation by Aphasic Patients

The ability to compensate for fixation of the jaw by a bite block was investigated in 6 nonfluent aphasics, 6 fluent aphasics, and 10 normal control subjects. Acoustic analyses of the vowels [i u a æ] and fricatives [s s] revealed substantial but incomplete compensation for the perturbation in all three subject groups. Perceptual identification scores and quality ratings by naive and phonetically trained listeners indicated poorer identification of the high vowels [i u] under compensatory conditions relative to normal production. Of particular interest was the fact that all three groups of subjects exhibited similar patterns of results. The findings suggest that any deficit in speech motor programming demonstrated by the nonfluent aphasic patients did not affect compensatory abilities. Results are discussed with respect to normal speech adaptation skills and the nature of articulatory breakdown in nonfluent aphasia.     

The Effects of Food and Gender on Interpersonal Perceptions

Male and female subjects provided ratings of personal traits, femininity and masculinity, and total caloric consumption for a female or a male target based on the type of diet she or he had allegedly consumed. The gender associated with the foods presented for each dietary profile was manipulated. Results showed that Target Gender and Dietary Profile significantly affected impression ratings and calorie estimates. Both male and female subjects perceived male eaters and those who ate a feminine diet more favorably. Results are discussed in terms of the different underlying expectations held for males and females when food consumption is involved during the impression formation process.     

A preliminary scale to measure connected and separate knowing: The Knowing Styles Inventory

The present investigation reported the development and validation of the Knowing Styles Inventory (KSI), a scale to measure connected and separate knowing [M. F. Belenky, B. M. Clinchy, N. R. Goldberger, and J. M. Tarule (1986), Women's Ways of Knowing: The Development of Self, Voice, and Mind New York, Basic Books]. In Study 1, principal components analyses for samples of females (N = 300) and males (N = 253) yielded two components, Connected and Separate Knowing. Studies 2 and 3 focused on females exclusively. The results indicated adequate test—retest reliability and internal consistency for both components. Additionally, Connected Knowing was positively correlated with empathic concern, perspective-taking, social desirability, and the femininity factor of the Bem Sex Role Inventory (BSRI). Separate Knowing was positively correlated with the masculinity factor of the BSRI and negatively correlated with social desirability. Suggestions for future research were presented.The authors wish to thank Jill Mattuck Tarule for the insight that she offered in the early stages of this project, and they wish to acknowledge the contribution of Nicole Bressler who participated in item development.     

The role of direct-care staff

This article examines the current role of direct-care staff, and their significance to individuals with disabilities living in the community. The role of staff will be redefined with respect to client normalization within the community. Finally, a framework for training staff is provided.     

Resetting the pitch-analysis system: 1. Effects of rise times of tones in noise backgrounds or of harmonics in a complex tone

The question of whether sudden increases in the amplitude of pure-tone components would perceptually isolate them from a more complex spectrum was investigated in two experiments. In Experiment 1, a 3.5-sec noise was played as a masker. During the noise, two pure-tone components of different frequencies appeared in succession. Subjects were asked to judge whether the pitch sequence went up or down. The rise time of these components had only a small and inconsistent effect on discrimination. In Experiment 2, the 3.5-sec background signal was a complex tone. The amplitudes of two of its components were incremented in succession. Again, subjects judged whether the pitch pattern went up or down. This time there was a sizable, monotonic effect of the rise time of the increments, with more rapid increments leading to better discrimination. The difference between the two results is interpreted in terms of the auditory system’s response to changing and unchanging signals and the role of its “sudden-change” responses in attracting perceptual processing to certain spectral regions.     

Conceptual memory for picture and prose episodes

In two experiments, subjects decided whether probes were true or false of one of some previously studied picture and prose episodes. The results indicated that response times to probes depicting explicit events were faster when they were in the same modality (picture or prose) as their episodes than when they were in the opposite modality, but response times to probes depicting implicit events were as fast when they were in the opposite modality as when they were in the same modality. These results suggest that the conceptual representations of picture and prose episodes are identical in form. The second experiment indicated that probes could be evaluated as fast from long as from short episodes. This result is consistent with the notion that retrieving information from episodes is done, not by scanning all the events of an episode, but by restricting the search only to the relevant slot in the schema into which the episode is assimilated.     

The role of cosmetics in attributions about sexual harassment

The purpose of this study was to investigate the effect of cosmetics use on attributions concerning the likelihood of provoking sexual harassment and of being sexually harassed. Subjects were 85 female and 76 male undergraduate volunteers. The study was a 3×2 between-subjects design with three levels of cosmetics use (heavy, moderate, no cosmetics) and two levels of sex of subject (male, female). Each subject viewed one of three colored photographs of a model wearing either heavy, moderate, or no cosmetics, and then indicated how likely the model was to provoke sexual harassment and to be sexually harassed. Data were analyzed using analyses of variance and the Newman-Keuls test. When the model wore heavy cosmetics, she was rated as more likely to provoke sexual harassment than when she wore moderate cosmetics. Similarly, when the model wore moderate cosmetics, she was rated as significantly more likely to provoke sexual harassment than when she was not wearing cosmetics. When the model wore either heavy or moderate cosmetics, she was also rated as more likely to be sexually harassed than when she did not wear cosmetics. In addition, male subjects rated the model as more likely to provoke and to be sexually harassed than did female subjects. Results are discussed in terms of sex role spillover.     

Invariance of the weight parameter in information integration

The relative effect of each informational dimension in an information integration task is a joint function of its weight and the range of values over which it is varied. A method is developed for separating these two factors. Weights obtained by this method were compared across variations of stimulus range. Subjects rated the performance of students on the basis of midterm exam scores and final exam scores. For some subjects, the range of scores on the final exam was twice that on the midterm and the reverse was true for other subjects. An averaging model was shown to describe the results, and weights did not differ for different stimulus ranges. This was true for each of two instructional conditions: one in which a particular weighting strategy was prescribed and one in which there was no prescribed weighting. Students who were instructed to use a 2∶1 weighting were found to assign more than twice as much weight to the final as to the midterm.
