Does the Organization of Emotional Expression Change Over Time? Facial Expressivity From 4 to 12 Months

Differentiation models contend that the organization of facial expressivity increases during infancy. Accordingly, infants are believed to exhibit increasingly specific facial expressions in response to stimuli as a function of development. This study tested this hypothesis in a sample of 151 infants (83 boys and 68 girls) observed in 4 situations (tickle, sour taste, arm restraint, and masked stranger) at 4 and 12 months of age. Three of the 4 situations showed evidence of increasing specificity over time. In response to tickle, the number of infants exhibiting joy expressions increased and the number exhibiting interest, surprise, and surprise blends decreased from 4 to 12 months. In tasting a sour substance, more infants exhibited disgust and fewer exhibited joy and interest expressions, and fear and surprise blends over time. For arm restraint, more infants exhibited anger expressions and anger blends and fewer exhibited interest and surprise expressions and surprise blends over time. In response to a masked stranger, however, no evidence of increased specificity was found. Overall, these findings suggest that infants increasingly exhibit particular expressions in response to specific stimuli during the 1st year of life. These data provide partial support for the hypothesis that facial expressivity becomes increasingly organized over time.     

Lawyers in the legislature: The case of Ohio

Do lawyer-legislators differ significantly from their non-lawyer colleagues? This question is significant given the large number of lawyers occupying state and federal legislatures. The predominant theory of “professional convergence” holds that lawyer-legislators and non-lawyer-legislators exhibit no significant differences. In examining the Ohio General Assembly, this study finds that lawyers tend to be more ambitious, and think of their legislative roles differently than their non-lawyer associates. The study concludes that convergence theory needs to be revised to become attuned to present day realities of law and politics.     

Parenthood and Marital Satisfaction: A Meta‐Analytic Review

This meta‐analysis finds that parents report lower marital satisfaction compared with nonparents (d=?.19, r=?.10). There is also a significant negative correlation between marital satisfaction and number of children (d=?.13, r=?.06). The difference in marital satisfaction is most pronounced among mothers of infants (38% of mothers of infants have high marital satisfaction, compared with 62% of childless women). For men, the effect remains similar across ages of children. The effect of parenthood on marital satisfaction is more negative among high socioeconomic groups, younger birth cohorts, and in more recent years. The data suggest that marital satisfaction decreases after the birth of a child due to role conflicts and restriction of freedom.     

Self-advocates have the last say on friendship

This study reports the friendship experiences and aspirations of adults with intellectual disabilities. The findings of a larger study were reviewed by an expert group of self-advocates with intellectual disability. The expert group confirmed some of the interpretation of the original data and expanded on issues. Friendship is established as an issue of concern among adults with intellectual disability. Consequently, policy-makers and service providers need to be intentional about providing support for friendships. Participants asserted a positive self-identity of being a person with intellectual disability and how this could be a basis for friendship. Also, people with intellectual disability demonstrated how they should be considered experts in their own life experience and how they can be effectively included in the formulation, implementation, analysis and review of research.     

Twenty-five years before the masthead: Confessions of a journal editor

After two-and-a-half decades as Editor of the Journal of Labor Research, I share some of my thinking about academic research in general and about journal editing, the review process, and the publishing game, in particular. This irreverent (and sometimes irrelevant) personal perspective should not be taken too seriously — indeed, journal editors should never take themselves too seriously.     

National Health Insurance: An Alternate Medical Viewpoint

Increasing medical technology, expertise and community expectations of health care are leading to an alarming escalation of health costs throughout the world. Many health planners are expressing doubts as to whether quality of health care can be maintained in the present circumstances. It is maintained that the Australian Government's proposal of National Health Insurance is an interim measure, intended to grant hospital and medical expenditure assistance to the entire community, at minimum cost. There is little evidence that the scheme threatens the medical market place, as it is seen at the moment, and a plea is made for productive and constructive discussion of the scheme by the medical profession.     

Sex selection with biased technologies and its effect on the population sex ratio

Current biomedical research on sex selection techniques may soon offer couples the opportunity to choose the sex of their children with greater certainty. A technique planned for marketing by mid-1978 can increase the probability of bearing a son to as much as 0.90. However, couples who wish to improve their chances of bearing a daughter have no such opportunity. The purpose of this paper is two-fold. First, a decision-making model is provided which describes how couples should choose among alternative sex-selection methods so as to maximize the probability of bearing their desired number of sons and daughters. Second, the effect of the widespread use of sex-selection techniques on the population sex ratio is explored. It is shown that even if populations have unbiased sex preferences, or sex preferences biased towards daughters, the use of biased sex-selection technologies may result in very high population sex ratios.
