Child‐Care Usage and Mother‐Infant “Quality Time”

Mothers' time‐use patterns were compared in families in which infants spent more than 30 hours per week in child care (In‐Care group; n= 143) versus 0 hours per week (At‐Home group; n= 183) from birth to 6 months of age. In‐Care group mothers spent about 12 fewer hours per week interacting with their infants, for about 32% less time; fathers of these infants were more involved in caregiving. The groups did not differ in the quality of mother‐infant interaction. In the In‐Care group, quantity of interaction was related to greater separation anxiety and concerns about effects of maternal employment. Time‐use data were not related to child outcomes at 15 months of age. Results suggest that the effect of extensive time spent apart on the quantity and quality of mother‐infant interaction may be smaller than anticipated.     

Compatibility,Leisure, and Satisfaction in Marital Relationships

This study challenges the prevailing view that marital companionship promotes marital satisfaction. By following a cohort of married couples for over a decade and by incorporating several methodological improvements—such as refining the measurement of marital satisfaction, determining how much spouses enjoy doing the leisure activities they pursue together and apart, and using diary data to portray marital leisure patterns—we found that the association between companionship and satisfaction is less robust than previously believed, and that it depends on how often spouses pursue activities that reflect their own and their partner's leisure preferences. Over time, involvement in leisure liked by husbands but disliked by wives, whether as a couple or by husbands alone, is both a cause and a consequence of wives' dissatisfaction.     

Studying and Measuring Civility: A Framework, Trends and Scale

Four essential questions for the study of civility involve developing a definition of the term, determining its effects, establishing trends, and predicting the consequences of civility. A framework for studying it includes the actors, their gender, situations and settings, occupational role requirements, the cultural imperatives defining civility, and the processes through which it is learned. Objective measures of civility in the United States show its variability and change. Four items in the 1996 General Social Survey (GSS) are combined to form a scale of civility. Correlates of the scale show that civility does not differ by gender, color, or region. It is weakly associated with income but is significantly associated with education, occupation, and health. Age, education, and health provide a predictive model of civility. Anger, an emotional aspect of interpersonal exchange, reveals reactions characteristic of civil behavior: waiting for anger to pass before responding, trying to forget the incident, not thinking of revenge, not walking away from the situation, and not yelling or hitting. Hypotheses are proposed for further study that involves age, marital status, occupation, health, and emotional control.     

Understanding Unemployment Across California Counties

Unemployment rates differ widely and persistently across counties. This article examines equilibrium forces related to this geographic disparity with a focus on California. We show that although seasonal variation in employment can account for some of the differences, it cannot explain the total variation. Factors such as educational attainment, age, and gender appear to be strongly related to unemployment differences. Individuals living in higher‐unemployment areas also have a lower propensity to migrate. Because migration is usually considered to be the main equilibrating force, this evidence helps further explain why unemployment rates across counties are persistently different.     

The Psychological Adjustment of Transracial Adoptees: An Application of the Cultural–Racial Identity Model

In response to the need for increased understanding of the identity process of transracial adoptees, the Cultural–Racial Identity Model (A. L. Baden & R. J. Steward, 1995) was developed; however, the model has yet to be empirically validated. The model allows distinctions to be made between racial identity and cultural identity, resulting in 16 proposed identities. Identities are based on the degrees to which individuals (1) have knowledge of, awareness of, competence within, and comfort with their own racial group's culture, their parents' racial group's culture, and multiple cultures, and (2) are comfortable with their racial group membership and with those belonging to their own racial group, their parents' racial group, and multiple racial groups. Four dimensions of the model were determined for study: the Adoptee Culture Dimension, the Parental Culture Dimension, the Adoptee Race Dimension, and the Parental Race Dimension. In this study, the Cultural–Racial Identity of transracial adoptees was assessed by a modified version of the Multigroup Ethnic Identity Measure (MEIM; J. S. Phinney, 1992). Psychological adjustment was assessed by the Brief Symptom Inventory (BSI; L. R. Derogatis & P. A. Cleary, 1977). The sample consisted of 51 transracial adoptees who completed mail survey questionnaires. The exploratory findings supported the Cultural–Racial Identity Model by demonstrating that the modified version of the MEIM successfully yielded variation in the potential Cultural–Racial Identities that the transracial adoptees reported. Findings also did not yield support for differences in psychological adjustment among transracial adoptees having different Cultural–Racial Identities. The implications that the results have for counseling practice and social policy were discussed.     

Factors Associated with Having Flextime: A Focus on Married Workers

To examine flexible work scheduling of married workers a conceptual framework was developed and tested using the 1997 Current Population Survey Work Schedules Supplement. Odds of flextime use were higher for married males, non-Hispanic whites, those with relatively higher levels of education and income, those with a preschool aged child, residents of the Midwest or West (as compared with the South), managers or professionals, and employees of the federal government.     

Infants' Ability to Learn Phonetically Similar Words: Effects of Age and Vocabulary Size

What do novice word learners know about the sound of words? Word‐learning tasks suggest that young infants (14 months old) confuse similar‐sounding words, whereas mispronunciation detection tasks suggest that slightly older infants (18–24 months old) correctly distinguish similar words. Here we explore whether the difficulty at 14 months stems from infants' novice status as word learners or whether it is inherent in the task demands of learning new words. Results from 3 experiments support a developmental explanation. In Experiment 1, infants of 20 months learned to pair 2 phonetically similar words to 2 different objects under precisely the same conditions that infants of 14 months (Experiment 2) failed. In Experiment 3, infants of 17 months showed intermediate, but still successful, performance in the task. Vocabulary size predicted word‐learning performance, but only in the younger, less experienced word learners. The implications of these results for theories of word learning and lexical representation are discussed.
