TAILIEUCHUNG - VARIATION IN REPRODUCTIVE STRATEGIES INFLUENCES POST-COITAL EXPERIENCES WITH PARTNERS

There have been multiple studies of programs focused on positive youth outcomes in general and on reproductive health behaviors in particular. Many programs show promising results, although there have been few rigorous experimental replication studies. See the “what works” table at the end of the chapter for details on specific programs. Addressing early educational experiences appears to be associated with reduced pregnancy and childbearing years later, as is evidenced by two preschool / child care programs that focused on strengthening educational outcomes among disadvantaged children (Horacek et al., 1987; Schweinhart, Barnes & Weikart, 1993). . | Journal of Social Evolutionary and Cultural Psychology - 2010 4 4 254-264.

Kruger Institute for Social Research and School of Public Health University of Michigan Ann Arbor Susan M. Hughes Department of Psychology Albright College Abstract The Post-Coital Time Interval PCTI may be particularly important for pair-bonding and establishing relationship commitment. Women have greater incentives for establishing relationship commitment than men because of their greater necessary investment in offspring and the benefits of long-term paternal investment. Thus sex differences in PCTI experiences may emerge based on sex differences in reproductive strategies. We generated 16 items to assess PCTI experiences and extracted three factors related to 1 satisfaction and bonding 2 a desire for more signals of bonding and commitment from one s partner and 3 romantic partners having a greater interest in talking about relationship issues. Consistent with our predictions women s satisfaction with PCTI experiences was inversely related to the extent to which they desired greater bonding and commitment signals from their partner whereas men s satisfaction with PCTI experiences was inversely related to the extent to which their partners had greater interests in talking about relationship issues. These dimensions were also related to other indicators of reproductive strategies including attachment style. Keywords Sex differences reproductive strategies commitment attachment life history Introduction This study investigated experiences with partners during the time interval immediately following sexual intercourse. There is a tremendous volume of research on human sexuality and in recent decades evolutionary researchers have generated a large body of literature on .
