Acoustic cues and psychological processes in the perception of natural stop consonants

These studies examined the perceptual role of various components of naturally produced stop consonants (/b, d, g, p, t, k/) in CV syllables. In the first experiment, the context-sensitive voiced formant transitions were removed with a computer-splicing technique. Identification accuracy was 84% when the consonant was presented with the same vowel as had been used to produce it. Performance fell to 66% when the consonant was juxtaposed with a different vowel. The second experiment not only deleted the voiced formant transition, but also replaced the aspiration with silence. Here, identification accuracy dropped substantially, especially for voiceless stops, which had contained devoiced formant transitions in the replaced interval. The pattern of errors suggested that listeners try to extract the missing locus of the consonant from the vowel transition, and in the absence of a vowel transition, they try to extrapolate it from the second formant of the steady-state vowel.     

Background characteristics and women's dual-role attitudes

This study examines the relationship between the attitudes toward the employment of married women held by 583 currently married Los Angeles County women between the ages of 18 and 49 and their personal backgrounds in terms of certain basic demographic characteristics. The findings illustrate that the respondents' attitudes significantly varied as a result of their personal backgrounds (e.g., level of education, ethnicity, marriage duration, income, work status, religion, age, and number of children raised). However, the data do not support the belief of Mason and Bumpass that women's dual-role attitudes are a group phenomenon determined by group norms or collectively held perceptions arising from the women's particular social niches; the demographic characteristics included in the study were able to explain only 27% of the observed variation in dual-role attitudes.     

Fathers: The invisible parent

Viewing the family as a system of interdependent roles has frequently led to the assumption that fathers, in comparison with mothers, play highly restricted roles vis-à-vis their children. Much of the literature on fathers, in point of fact, stresses their absence, their disinterest, and lack of competence in child care. Reported here are findings from a sample of 231 families which suggest that this conception of fatherhood does an injustice to the empirical case. The evidence indicates that when the amount of time available to spend with children is considered, the father's involvement with his children is equal to that of the mother's. Under certain conditions, in fact, father-child involvement exceeds the child-related activities performed by mothers.     

A contribution to the understanding of the role of the superego in dreams: Further development of an approach to dreams in analytic group psychotherapy

Seven dreams from patients in three different groups are presented to illustrate the author's ego-psychological approach to dreams in group under varying conditions as well as to emphasize particular concepts regarding the role of the superego in the dream. This paper demonstrates how the author addresses group process, individual functioning and the dream simultaneously within the context of an ongoing therapeutic process. The first section of the paper points out that theoretical contributions towards an understanding of the dream, since its original position of importance, have been almost nonexistent. The author believes the significance of the superego throughout the analytic process as well as in theory has been underestimated.Dr. Edwards is an Associate Supervisor and Faculty Member at the Postgraduate Center for Mental Health in the Group Department.

Developmental changes in incidental memory as a function of processing level,congruity, and repetition

Second-, fifth-, and ninth-grade students (8, 11, and 14 years of age, respectively) answered acoustic and semantic questions about words which were either congruent or incongruent with the questions. Subsequently, students' free recall of the words was unexpectedly tested. For words presented once in the list, only orienting task and congruity main effects were found. For twice-presented words, grade level interacted with both variables in that older students' recall was better than younger students' only for semantically encoded, congruent words. This finding is consistant with the hypothesis that developmental increases in semantic knowledge enhance the potential for encoding elaboration, but is in apparent conflict with the results of M. F. Geis and D. M. Hall (Child Development, 1978, 49, 857–861) who found no such interaction for second- and fifth-grade children. The different age spans included in the two studies provides one resolution of the discrepancy in results. However, a second experiment tested the importance of a procedural difference between the two studies. M. F. Geis and D. M. Hall (Journal of Experimental Child Psychology, 1976, 22, 58–66; 1978) presented the question after the stimulus word while we presented the question before the word. For ninth-grade students, the question after condition resulted in an attenuation of the recall difference between semantic and acoustic questions compared to the question before condition. It was argued that the pattern of developmental differences in incidental memory that is obtained may be related to which procedure is utilized.     

Development and the continuum of dimensional separability

Recent studies of adult perception may be interpreted in terms of a continuum from the integral to the separable perception of multidimensional variation. Three experiments examined the existence of such a continuum across developmental levels. These experiments are important because several developmental studies suggest that the separability of dimensions increases with age. Despite this assumed developmental trend, it was hypothesized that therelative separability of dimensions does not change with age. The results of the three experiments did not support the hypothesis. The ordering of dimensions by their relative separability changes with development. These results suggest that the relative separability and potential separability of dimensions are not fixed. In light of the results, it is hypothesized that the integrality or separability of dimensions in adult perception is primarily determined by perceptual learning and not by the inherent characteristics of combinations of stimulus dimensions.     

The role of free choice in memory for past decisions

After choosing between different options, people tend to remember the features of the options in ways that favour the chosen alternative. The present experiment examined how limitations on freedom to choose between options affected this memory bias. Participants were given a series of two-option choices and were either allowed free choice between options or were assigned to an option. Participants assigned to an option were led to believe that either the selection was random or was made in their best interest based on their personality profile. Results indicated that the choice and best interest conditions demonstrated memory attributions that favoured their received options, whereas the assignment condition did not. These findings support the view that memory biases towards received options are not unique to free choice situations, but may stem from expectations and implicit theories about how and why the choice was made.     

The Best Friendships of Shy/Withdrawn Children: Prevalence, Stability, and Relationship Quality

The mutual best friendships of shy/withdrawn and control children were examined for prevalence, stability, best friend's characteristics, and friendship quality. Using peer nominations of shy/socially withdrawn and aggressive behaviors, two groups of children were identified from a normative sample of fifth-grade children: shy/withdrawn (n = 169) and control (nonaggressive/nonwithdrawn; n = 163). Friendship nominations, teacher reports, and friendship quality data were gathered. Results revealed that shy/withdrawn children were as likely as control children to have mutual stable best friendships. Withdrawn children's friends were more withdrawn and victimized than were the control children's best friends; further, similarities in social withdrawal and peer victimization were revealed for withdrawn children and their friends. Withdrawn children and their friends reported lower friendship quality than did control children. Results highlight the importance of both quantitative and qualitative measures of friendship when considering relationships as risk and/or protective factors.     

Neuroanatomical and behavioral asymmetry in an adult compensated dyslexic

Individual differences in cortical anatomy are readily observable, but their functional significance for behaviors such as reading is not well understood. Here, we report a case of an apparent compensated dyslexic who had attained high achievement in visuospatial mathematics. Data from a detailed background interview, psychometric testing, divided visual field tasks measuring basic word recognition (word naming, nonword naming, and lexical decision), and more controlled word retrieval (verb, category, and rhyme generation), and measurements of his atypical brain structure are described. The findings suggested that enhanced "top-down" processing could provide the means to compensate for deficient "bottom-up" word decoding skills in this case. Relative to controls, this individual also evidenced unusually large asymmetries on several divided visual field lexical tasks, an extreme leftward asymmetry of the planum temporale, and a rare form of Sylvian fissure morphology (Steinmetz type 4, [Steinmetz, H., Ebeling, U., Huang, Y., & Kahn, T. (1990). Sulcus topography of the parietal opercular region: An anatomic and MR study. Brain and Language, 38, 515-533.]). We suggest that certain forms of brain organization may be associated with successful behavioral compensation for dyslexia, and that anatomical variations in the right hemisphere may be important contributors to individual differences in reading acquisition and achievement.     

Risk perceptions, worry, and attitudes about genetic testing for breast cancer susceptibility

This study assessed the unique associations of risk perceptions and worry with attitudes about genetic testing for breast cancer susceptibility. Women (general practitioner clinic attenders, university students, and first-degree relatives of breast cancer survivors; N?=?303) read information about genetic testing and completed measures assessing perceived cancer risk, cancer worry, and genetic testing attitudes and beliefs. Worry was associated with greater interest in genetic testing, stronger beliefs that testing has detrimental emotional consequences, and positive beliefs about benefits of testing and risk-reducing surgeries. Perceived risk was unrelated to interest and associated with more skeptical beliefs about emotional consequences and benefits of testing and risk-reducing surgeries. At low worry levels, testing interest increased with more positive beliefs about testing benefits; at high worry levels, interest was high regardless of benefits beliefs. The findings support Leventhal's Common-Sense Model of self-regulation delineating interactive influences of risk-related cognitions and emotions on information processing and behavior.
