Sources of variability in children’s language growth

The present longitudinal study examines the role of caregiver speech in language development, especially syntactic development, using 47 parent–child pairs of diverse SES background from 14 to 46 months. We assess the diversity (variety) of words and syntactic structures produced by caregivers and children. We use lagged correlations to examine language growth and its relation to caregiver speech. Results show substantial individual differences among children, and indicate that diversity of earlier caregiver speech significantly predicts corresponding diversity in later child speech. For vocabulary, earlier child speech also predicts later caregiver speech, suggesting mutual influence. However, for syntax, earlier child speech does not significantly predict later caregiver speech, suggesting a causal flow from caregiver to child. Finally, demographic factors, notably SES, are related to language growth, and are, at least partially, mediated by differences in caregiver speech, showing the pervasive influence of caregiver speech on language growth.     

Just the thought of it!: Effects of anticipating computer-mediated communication on gender stereotyping

A study investigated how anticipated communication mode affects the use of stereotypes in forming impressions and making task assignments. Participants rated male or female targets with whom they envisioned working on a business project using computer-mediated or face-to-face modes of communication. Results indicated that both men and women were characterized more stereotypically when participants anticipated working with them electronically than when they anticipated working with them face-to-face. Furthermore, task assignments were more often gender stereotype consistent when the communication mode was computer-mediated than when it was face-to-face. These findings suggest that the mere anticipation of computer-mediated communication, without the actual the experience of it, is enough to promote stereotypes and biased decision-making.     

Childhood amnesia: Empirical evidence for a two-stage phenomenon

The term childhood amnesia refers to the inability of adults to remember events from their infancy and early childhood. If we plot the number of memories that adults can recall as a function of age during childhood, the number of memories reported increases gradually as a function of age. Typically, this finding has been used to argue that gradual changes in memory development contribute to a gradual decline in childhood amnesia during the preschool period. Alternatively, it is possible that pooling data across participants has obscured more abrupt, stage-like changes in the remission of childhood amnesia. In the present study we examined the number and distribution of childhood memories for individual participants. Six adults were repeatedly interviewed about their childhood memories. We found that the distribution of adults' early childhood memories may be less continuous than pooled data suggest. This finding has important implications for current explanations of childhood amnesia.     

A Developmental Evaluation of Frequency Memory for Actions Presented in Lists,Scripts, and Stories

Although some research suggests that misinformation provided by a co-witness could be more influential than that obtained from other sources, most of this research has compared the effect of co-witness information against non-social forms of misinformation only. To better understand the influence of co-witnesses we compared the influence of co-witness misinformation with the influence of misinformation provided by an interviewer. Across two experiments using the MORI paradigm we found no evidence that a co-witness is particularly influential relative to another social source of post-event misinformation. In fact, the source of the misinformation delivered by our interviewer was less likely to be correctly recalled than the source of the misinformation delivered by a co-witness. There was some evidence that misinformation delivered by both a co-witness and an interviewer has a stronger effect on witnesses' accuracy and confidence than misinformation obtained from either source alone. Finally, our results suggest that the opportunity to provide an early individual memory account might protect against the effect of subsequently-encountered co-witness misinformation. These results have important implications for the way that criminal investigations are conducted.     

Sport-Type Differences in Alcohol Use Among Intercollegiate Athletes

Prior research has found that (a) intercollegiate athletes are especially “at-risk” for excessive alcohol consumption (e.g., Nelson & Wechsler, 2001 Nelson, T. F. and Wechsler, H. 2001. Alcohol and college athletes. Medicine and Science in Sports and Exercise, 33: 43–47. [INFOTRIEVE][CSA][CROSSREF][Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), and (b) sport-type differences exist among college athletes in terms of yearly drinking prevalence rates (National Collegiate Athletic Association, 2001 National Collegiate Athletic Association. 2001. NCAA study of substance use habits of college student-athletes, Indianapolis, IN: Author.  [Google Scholar]). No studies, however, have examined sport-type differences on more specific measures of alcohol consumption (e.g., drinks per week), or examined potential mediators of the relationship between sport type and alcohol consumption. In the present study, data were analyzed on 298 intercollegiate athletes from two different universities. Resuls indicated significant sport type differences on alcohol consumption variables, with athletes from the sports of swimming and diving reporting the highest levels of alcohol consumption. Results provided partial support for the role of positively reinforcing drinking motives in mediating the sport type–alcohol consumption relationship. Findings are discussed in light of prior research in the area of college student–athlete alcohol consumption.     

Sex bias in evaluating nontraditional job applicants: reactions to women and men's interrupted college attendance

Two studies indicated that being a nontraditional job applicant due to voluntary interruption of college attendance had detrimental consequences for employment evaluation. These negative reactions were more severe for women than for men. Women with interrupted attendance received the most negative responses (Studies 1 and 2). Choosing to interrupt college attendance increased perceived instability and also positively affected perceived flexibility, and these characterizations were related to evaluative outcomes (Study 2). Moreover, both instability and flexibility characterizations contributed to the gender‐discrepant consequences of interrupted college attendance. Female applicants were rated more negatively on flexibility characterizations than were male applicants. Furthermore, although there were no gender differences in ratings of instability, instability ratings were found to negatively impact evaluations of female applicants, but not male applicants.     

The Meaning of Rorschach Inkblots,Responses and Determinants as Perceived by Children

Fifteen semantic-differential scales were applied to the Rorschach inkblots, to nine common Rorschach responses representing various Rorschach determinants, and to two determinants not embodied in responses. Ss consisted of third, sixth, and ninth grade public school children separated by sex within each group. Children significantly differentiated the inkblots on the semantic scales, with older children differentiating the blots more sharply. Girls differentiated the blots at an earlier age than did boys. Individual cards differed widely in regard to their strongest connotations. Children significantly differentiated the majority of responses and determinants on the semantic scales for all age groups. The connotations of the cards, responses and determinants tended to be consistent with commonly held Rorschach interpretations. In general, the findings for children were consistent with the results previously reported for adults. The connotations of chromatic inkblots were found to differ significantly from those of achromatic blots for the third and ninth grades, but not for sixth grade children. Statistically significant clusters of meaning for three age groups of children were found to exist, based on the presence of movement determinants and on a combination of movement, shading and chromatic color. Only for the sixth and ninth grade girls did the semantic scales have a single hierarchy of importance for ordering or differentiating both inkblots and responses of determinants. A communality of connotative meaning between inkblots on the one hand, and responses and determinants commonly associated with the blots on the other, is found only for ninth grade children. Low intergroup agreement was found across grades in mean scale ranking for the inkblots, but high agreement in mean scale ranking of responses and determinants.     

Measuring Generalized Expectancies for Negative Mood Regulation: Initial Scale Development and Implications

A scale measuring generalized expectancies for negative mood regulation (NMR) was developed. The construct was defined as the expectancy that some behavior or cognition will alleviate a negative mood state. Data from five samples of college undergraduates (N = 1,630) were reported. Internal consistency, discriminant validity from social desirability, and temporal stability were demonstrated for a 30-item scale derived from an initial pool of 50 items. Further analyses revealed (a) modest correlations of the 30-item scale with internal-external control, (b) that high scorers on the NMR scale reported few symptoms of depression, and (c) that the NMR scale predicted a different pattern of emotions than the Beck Depression Inventory did. Discussion focused on possible roles for expectancies for negative mood regulation in the coping process and directions for future research on the mood regulation process.     

The Effects of Religiosity on Preferences and Expectations for Marital Therapy Among Married Christians

Highly religious couples constitute a substantial portion of marital therapy clients in the U.S. Married Christian individuals ( N = 211) completed a survey of demographics and religiosity (religious values and Christian beliefs). They rated preferences and expectations for one of four marital therapy situations: Christian therapist using Christian practices (e.g., prayer or reference to Scripture), Christian therapist using psychological practices only, non-Christian therapist willing to use Christian practices, and non-Christian therapist using psychological practices only. High religious values and high Christian beliefs predicted ratings of marital therapy situations, where high was defined as one standard deviation above the mean of standardized norm groups. Low to moderate religious values or Christian beliefs did not predict ratings of marital therapy. It was concluded that highly religious couples present a special situation where the marketing, assessment, and practice of marital therapy might differ from therapy with other types of couples.
