Cognitive influences on cross-language speech perception in infancy

Previous research has shown that young infants can discriminate both native and nonnative phonetic contrasts with ease. By 10 to 12 months of age, however, infants—like adults—typically have difficulty discriminating consonant contrasts that are not used to distinguish meaning in their native language. Although the timing of this change in speech perception has been firmly established, little is currently known about the processes or mechanisms involved in this selective and adaptive reorganization in nonnative phonetic discrimination. This study was designed to determine if there is a relation between age-related changes in speech perception performance and other developing cognitive abilities. A total of 40 8- to 10-month-old infants were tested on a nonnative consonant discrimination task and then on two additional tasks (a visual categorization task and an object search task) in an attempt to determine whether changes in nonnative consonant perception coincide with changes in these other areas of cognitive/perceptual functioning. The results indicate that changes in task performance occur in synchrony across all three tasks, and that this synchrony is not explained by simple age effects. These findings suggest that domain-general cognitive/perceptual competencies may influence developmental changes in speech perception by the end of the 1st year of life.     

The role of emotion control and emotional rumination in stress management training

The present paper reports on three outcome studies evaluating the effectiveness of a new stress management training program. In contrast to conventional stress management, which tends to emphasize life-events, the symptoms of stress and relaxation, the new program is based on emotional rumination, emotion control, and attention control. The training developed from a series of experimental studies on the role of emotional inhibition and rumination in prolonging physiological recovery from stress, and the findings reported here were obtained from a series of applied studies involving police officers from a police force in the North of England. The first two studies employed both self-reported and objective measures of change to demonstrate that the training produced significant increases in job satisfaction and reduced absenteeism, while the results of the final study showed that the benefits of the program were enhanced by follow-up training.     

The Development of Communicative Competence of Securely and Insecurely Attached Children in Interactions with Their Mothers

Coordinated interpersonal timing in preverbal mother-child interactions is assumed to be one fundamental feature of interpersonal relatedness and the basis for parent-child bonding. The ubiquity of and early evidence for this phenomenon in ontogeny hint at its biological prewiredness and relevance for development. The quality of interpersonal timing in early preverbal parent-child interactions was hypothesized (and partially shown) to predict quality of attachment, level of cognitive functioning, and patterns of language acquisition. The aim of this study was to investigate the assumption of a facilitating effect of adequate interpersonal coordination (measured by quality of attachment) on the development of verbal communicative competence in children during the first stages of language development. On the basis of longitudinal data for 25 mother-child dyads, videotaped when the children were 17, 23, 30, and 36 months old in a free play and a short separation situation, it was investigated whether securely and insecurely attached children differ with respect to the amount of verbal contributions, their realization as alternating or simultaneous utterances, and the duration of intra-turn and inter-turn pauses. The results show that attachment was related to children's use of communicative competence especially in stressful situations, its development being paced by the age or maturation of the child.     

Gender differences in differentiating terms expressing certainty

Women's and men's understanding of the certainty expressed in mental and modal terms was examined. Subjects were asked to decide on the location of a hidden object when the only clue available was coded in the mental or modal term used in two conflicting assertions made by a male and female experimenter, each specifying a different location. Results showed that both women and men discriminated the degree of certainty expressed in 11 of 12 pairs of terms presented. Gender differences existed in the understanding of terms which were close in pragmatic meaning, with females making the distinctions more equivocally than males. The gender of the speaker had no influence on subjects' responses to contrasts which differentiated certainty, but on the contrast in which no preference for a term was found, subjects chose the location indicated by the male experimenter significantly more often. This study highlights a point of difference in pragmatic understanding between women and men and invites explorations of its origin.This research was supported by grant 410-89-0352 from the Social Sciences and Humanities Research Council of Canada to both authors.

The impact of family,peers, and educational personnel upon career decision making

This study examined the amount of support, encouragement, and discouragement women received from the important people in their lives when they considered enrolling in a male-traditional vocational course. Data were collected from 470 women enrolled in California vocational training programs. Approximately equal numbers of women in male-dominated (Nontraditionals) and female-dominated programs (Traditionals) completed the self-administered questionnaire. Among those in female-traditional programs, 117 had considered taking a nontraditional program, but never did (Considereds). Data were analyzed for each of these three groups. Results revealed the Nontraditionals consistently received more support and enocuragement than did the Traditionals. However, the only significant support differences between the Nontraditionals and Considereds were in terms of the males in their lives. The Considereds and Traditionals also expected more discouragement than the Nontraditionals indicated they had actually received. Recommendations are made to improve educational quality and to foster equality of educational opportunity.     

The cold glow of success: Responses to social rejection as affected by attitude similarity between the rejected and chosen individuals

Studied the effects of attitudinal similarity between two males on reactions to social rejection by a female. Sixty-five male undergraduate students had met an attitudinally similar or dissimilar male confederate. Later a female confederate either chose or did not choose the male confederate as a work partner. Following that, measures designed to tap subjects affective state and self evaluations were administered. Two way interactions for affect and self evaluations (p < 0.01 and p 7lt; 0.05 respectively) indicate that, relative to a control group, only subjects whose similar male partner was chosen expressed unfavorable affect and self-evaluations. The relevance of these findings for the affective consequences of social comparison processes is discussed.     

FACTORS THAT AFFECT NONTRADITIONAL VOCATIONAL ENROLLMENT AMONG WOMEN

This study identified the internal (personality) and external (social support) factors that differentiate women who enter male-dominated (Nontraditional) vocational training programs from those who only consider entering such programs (Considereds) and from those who enter female-dominated (Traditional) programs. Four hundred seventy women who were enrolled in California vocational training programs and were stratified on both social class and type of vocational training site completed a self-administered questionnaire covering (1) demographic/family background, (2) social support/encouragement from others, (3) peer experience with nontraditional programs, and (4) personality and sex-role orientation results revealed that the student subgroups differed most significantly in the amount of support, encouragement, and discouragement they received from the important others in their lives. Nontraditional students differed from Traditional students primarily in the support of female friends and family members, and from Considereds in encouragement from school personnel Recommendations are made for steps that can be taken to foster equality of educational opportunity.     

Audio-visual interactions with intact clearly audible speech

The effects of viewing the face of the talker (visual speech) on the processing of clearly presented intact auditory stimuli were investigated using two measures likely to be sensitive to the articulatory motor actions produced in speaking. The aim of these experiments was to highlight the need for accounts of the effects of audio-visual (AV) speech that explicitly consider the properties of articulated action. The first experiment employed a syllable-monitoring task in which participants were required to monitor for target syllables within foreign carrier phrases. An AV effect was found in that seeing a talker's moving face (moving face condition) assisted in more accurate recognition (hits and correct rejections) of spoken syllables than of auditory-only still face (still face condition) presentations. The second experiment examined processing of spoken phrases by investigating whether an AV effect would be found for estimates of phrase duration. Two effects of seeing the moving face of the talker were found. First, the moving face condition had significantly longer duration estimates than the still face auditory-only condition. Second, estimates of auditory duration made in the moving face condition reliably correlated with the actual durations whereas those made in the still face auditory condition did not. The third experiment was carried out to determine whether the stronger correlation between estimated and actual duration in the moving face condition might have been due to generic properties of AV presentation. Experiment 3 employed the procedures of the second experiment but used stimuli that were not perceived as speech although they possessed the same timing cues as those of the speech stimuli of Experiment 2. It was found that simply presenting both auditory and visual timing information did not result in more reliable duration estimates. Further, when released from the speech context (used in Experiment 2), duration estimates for the auditory-only stimuli were significantly correlated with actual durations. In all, these results demonstrate that visual speech can assist in the analysis of clearly presented auditory stimuli in tasks concerned with information provided by viewing the production of an utterance. We suggest that these findings are consistent with there being a processing link between perception and action such that viewing a talker speaking will activate speech motor schemas in the perceiver.
