Women’s hair as a cue to desired relationship and parenting characteristics

We investigated how women’s hair color (blond, brown, black) and length (short, medium, long) influences males’ judgments about the women’s age, health, physical attractiveness, relationship potential, and parenting capability. Results, which are generally consistent with evolutionary psychology approaches, indicate that hair color and, to a lesser extent, length can affect perceptions of personal characteristics. More specifically, we found that lighter hair (blond and brown) compared to darker hair (black) is generally associated with perceptions of youth, health and attractiveness, and generally leads to more positive perceptions of relationship and parenting potential. Furthermore, the relationships between variables suggest that characteristics directly related to reproductive potential may be inferred from more obvious indirect characteristics. These results suggest that males are able to make complex judgments about women concerning their desirable relationship and parenting potential based on discernable characteristics such as hair color and length.     

Children’s tactics of mate choice manipulation: Exploring sex differences and personality effects

Parents do not always agree with their children’s mating decisions, and so they attempt to manipulate them in accepting mates of their choice and in terminating relationships with undesirable ones. Children engage in counter-manipulation in order to avoid undesirable mates to be imposed on them and to persuade their parents to accept the mates they have chosen. This paper aims to identify the main factors that predict the tactics that children use on their parents. In particular, three hypotheses are tested, namely the use of manipulation tactics is predicted by the personality of children, by the sex of children and by the sex of parents. Evidence from two independent studies finds support for the first two hypotheses, but no support for the third hypothesis. The implications of these findings are further discussed.     

Do women perform fellatio as a mate retention behavior?

Men who report performing more mate retention behaviors, in general, and more benefit-provisioning mate retention behaviors, in particular, also report greater interest in, and spend more time, performing oral sex on their female partner. We extended these findings to a female sample to investigate whether women’s oral sex behaviors are related to their mate retention behaviors. We secured self-report data from 410 women residing in the United States or in Germany in a committed, sexual, heterosexual relationship. The results indicate that women who report performing more benefit-provisioning mate retention behaviors also report greater interest in, and spend more time, performing oral sex on their partner. Further, there are no sex differences in the magnitudes or directions of these relationships. The results suggest that both men and women are more interested in, and spend more time, performing oral sex on their partner as part of a benefit-provisioning strategy to increase their partner’s relationship satisfaction. We address limitations of this research, and discuss explanations for the results.     

Women’s mate retention behaviors,personality traits,and fellatio

Women perform oral sex on their male partner (i.e., fellatio) as part of a Benefit-Provisioning mate retention strategy, and women’s personality predicts their interest in, and time spent, performing fellatio. We explored whether women’s mate retention behavior mediates the relationship between their personality traits and their performance of fellatio in a long-term romantic relationship. Women (n = 401) reported their personality traits, the frequency with which they performed mate retention behaviors during the past month, and their interest in and the time they spent performing fellatio on their partner during their most recent sexual encounter. The results indicate that women higher in Conscientiousness spend more time performing fellatio on their partner, and this relationship is mediated by their Benefit-Provisioning mate retention. Women higher in Agreeableness report greater interest in performing fellatio on their partner, and less Cost-Inflicting mate retention, but mate retention behaviors do not mediate the relationship between their Agreeableness and their interest in performing fellatio. The current research is the first to investigate the relationship between women’s personality traits and oral sex behaviors, and contributes to research documenting that mate retention strategies are associated with sexual behavior.     

A Test of the Adams-Creamer Decay Hypothesis for the Timing of Motor Responses

The Adams-Creamer hypothesis states that S uses the decay of proprioceptive feedback from an early portion of a movement to cue a timed response at some later time. This hypothesis was tested by creating passive left-arm movement in one group and withholding it from another, and having Ss make a right-hand response when exactly 2.0 sec. had elapsed since the end of the movement Ss with left-arm feedback had less absolute and algebraic error, and greater within-S consistency than did the no-movement control Ss and, when KR was withdrawn, Ss with left-arm movement regressed less than did Ss without the left-arm movement, which provided 2 lines of support for the decay hypothesis.     

Impact de la motivation autodéterminée et de l’engagement affectif sur l’intention de rester : une étude chez les militaires

Conducted within the Canadian Forces (N=652), this study explores the role of self-determined motivation and affective commitment in relation to personnel retention within the military. Three groupings of variables are used in order to shed light on the mechanisms underlying personnel retention: a) distal antecedents (i.e. leadership styles), b) proximal antecedents (i.e. group cohesion and work climate) and c) mediators (i.e. self-determined motivation and affective commitment). Illustrated through a structural model, results demonstrate the existence of a partial mediator effect from affective commitment in the relationship between self-determined motivation and intention to stay. These findings are discussed in regards of their implications from theoretical and practical perspectives.
