Predicting conflict within romantic relationships during the transition to adulthood

We conducted a retrospective study between 1997 and 2000 with 200 participants in the Children in the Community Study at their mean age of 29 (range: 27–31 years). Participants completed detailed narrative interviews about their transition to adulthood and described monthly levels of partner conflict that had occurred between ages 17 and 27. Data from these interviews were used to investigate the developmental trajectory and predictors of conflict in romantic relationships. Multilevel growth models showed that partner conflict increased between ages 19 and 25 and then declined slightly. Parental divorce, low parental socioeconomic status, being an only child, being divorced, being married, cohabiting, and having biological offspring were associated with elevated partner conflict. Different patterns of association between these variables and partner conflict were observed in men and women.     

The Impact of Need for Achievement Components on Goal Commitment and Performance

A laboratory study examined the effects of components of need for achievement on goal commitment and performance. It was predicted that need for mastery and need for work are related to goal commitment. It was also predicted that need for mastery and need for work are more highly related to goal commitment than competitiveness, given the characteristics of the task environment. Finally, goal commitment was expected to mediate the effects of need for mastery and need for work on performance. Fifty-four undergraduate students performed nine trials of a complex task and completed a need for achievement scale composed of four subscales. Support was obtained for the first two predictions, and evidence of a sequential model partially supported the third prediction.     

When similars do not attract: Tests of a prediction from the self‐expansion model

This study tested the hypothesis from the self‐expansion model that the usual effect of greater attraction to a similar (vs. dissimilar) stranger will be reduced or reversed when a person is given information that a relationship would be likely to develop (i.e., that they would be very likely to get along) with the other person. The study employed the “bogus stranger” paradigm and focused on similarity/dissimilarity of interests in the context of attraction to a same‐gender other. The effect for similarity under conditions in which no information is given about relationship likelihood replicated the usual pattern of greater attraction to similars. However, as predicted, a significant similarity by information interaction demonstrated that this effect was significantly reduced (and slightly reversed) when participants had been given information that the partner will like self. In analyses for each gender separately, both of these effects were significant only for men, suggesting that the focus on interest similarity may have been less relevant for women.
