Improving Children's Mental Rotation Accuracy With Computer Game Playing

The authors investigated the relation between mental rotation (MR) and computer game-playing experience. Third grade boys (n = 24) and girls (n = 23) completed a 2-dimensional MR test before and after playing computer games (during 11 separate 30-min sessions), which either involved the use of MR skills (the experimental group) or did not involve the use of MR skills (the control group). The experimental group outperformed the control group on the MR posttest but not on the pretest. Boys outperformed girls on the pretest but not on the posttest. Children whose initial MR performance was low improved after playing computer games that entailed MR skills. The findings imply that computer-based instructional activities can be used in schools to enhance children's spatial abilities.     

Marital Satisfaction and Quality of Father–Child Interactions: The Moderating Role of Child Gender

The authors aimed to investigate the prospective links between normative variation in fathers’ marital satisfaction and the observed quality of father–toddler interactions, as well as the moderating role of child gender in these associations. Sixty-three fathers reported on their marital satisfaction when their children were 15 months of age, and were observed interacting with their child at 18 months. The results suggested that marital satisfaction was positively associated with the quality of father–son interactions, while no relations emerged among fathers of girls. These findings reiterate the importance of marital relationships for the quality of fathers’ parenting, while reaffirming previous suggestions that the role of child gender in the marriage-parenting connections requires further investigation.     

The Performance of Hamsters in the Maze Situation Utilizing Gravitation and the Vestibular Sense as Motivation

The hypotheses of this study of sex differences on a measure of self-esteem are as follows: 1) the scales good, nice, generous, pleasant, dependable, honest, and active will group together to form the outer esteem dimension of the semantic differential; 2) the scales strong, leader, powerful, confident, curious, inventive, sharp, and active will group together to form the inner esteem dimension of the semantic differential; 3) males will score significantly higher than females on the inner esteem dimension of the semantic differential; 4) females will score significantly higher than males on the outer esteem dimension of the semantic differential; 5) there will be a significant difference between the scoring patterns of males and females on the two dimensions of the semantic differential after controlling for the effects of race and social desirability. The sample of 442 sixth through eighth grade students consisted of two subsamples made heterogeneous on race, geographic location, and type of school. The Franks-Marolla Self-Esteem Semantic Differential and the Lunneborg and Lunneborg Child's Social Desirability Scale were administered. The findings support each of the hypotheses and indicate that there is a significant difference between the sexes on the Franks-Marolla Semantic Differential Measure of Self-Esteem. It is concluded that additional research in self-esteem might specify the meaning of sex differences in esteem by measuring esteem relative to an individual's structural social positions rather than measuring esteem in the general and environmentally nonspecific contexts as advocated by some.     

Effect of Age and Gender in the Control of Elbow Flexion Movements

In previous studies of rapid elbow movements in young healthy men, characteristic task-dependent changes in the patterns of muscle activation when movement speed or distance was varied have been reported. In the present study, the authors investigated whether age or gender is associated with changes in the patterns of muscle activity previously reported in young men. Arm movements of 10 healthy older and 10 healthy younger participants (5 men and 5 women in each group) were studied. Surface electromyograms (EMGs) from agonist (biceps) and antagonist (triceps) muscles, kinematic and kinetic parameters, as well as anthropometric and strength measures were recorded. All 4 groups of participants showed similar task- (distance or speed) dependent changes in biphasic EMG activity. Similar modulation of the initial rate of rise of the EMG, integrated agonist and antagonist EMG activity, as well as their relative timing were observed in all 4 groups. Those results suggest that older individuals of both genders retain the control strategies for elbow movements used by young individuals. Despite the qualitative similarities in the patterns of muscle activation, the men moved more quickly than the women, and younger participants moved more quickly than older participants. Those performance differences could not be explained in terms of differences in body size and strength alone.     

Adult Age and Gender Differences in Perceptions of Facial Attractiveness: Beauty is in the Eye of the Older Beholder

The authors examined ratings of facial attractiveness, rankings of faces, and reasons given by young, middle-aged, and older men and women for young, middle-aged, and older male and female face attractiveness. No support for predictions derived from similarity, interest, and cohort hypotheses was obtained. In support of the expertise hypothesis, young and middle-aged adults rated younger faces as more attractive than old faces, whereas older adults rated all aged faces equally. In support of the crone hypothesis, older female faces were rated the lowest of all faces. Theoretical implications and real-world applications are discussed.     

A Note Regarding the Validity of Lee's Typology of Love

In the present study, we investigated how well Lee's (1973/1976) typology of love characterized response data that adult subjects provided on selected items written by Hendrick and Hendrick. Results suggest that the model represents response data reasonably well and that Hendrick and Hendrick's (1986) measure ought to be valid.     

Children's Perception of Parental Empathy as a Precursor of Children's Empathy in Middle and Late Childhood

The present study investigated the relationship between children's self-concepts and evaluations of parent figures. The subjects were elementary school children (352 males and 280 females; Grades 5 through 10) who came from intact families, divorced families, or families in which one or both parents had died. Significant relationships were obtained between children's self-concept ratings and their evaluations of their natural father and mother for both intact and divorced families. This relationship was not significant, however, for families in which a parent had died. Furthermore, children's self-ratings were not significantly correlated with their evaluations of stepparents.     

The Prediction of Students' Satisfaction with Community College Vocational Training

The present study was conducted with 1,632 college vocational students in North Carolina to test the job satisfaction postulate of Rusbult's (1980a) investment model. The model postulate, that satisfaction is a function of perceived positive and negative outcomes, received support and proved to be defensible even after controlling for a broad array of situational variables. This postulate has also received empirical support from studies of satisfaction with business relationships, friendships, and romantic associations. The present study also introduced a new measure of outcomes: the Perceived Outcomes of College Life measure.     

How Do Romantic Relationship Satisfaction,Gender Stereotypes,and Gender Relate to Future Time Orientation in Romantic Relationships?

The present study is an investigation into how romantic relationship satisfaction and attitudes toward gender stereotypes about romantic relationship and gender are related to future time orientation in romantic relationships (FTORR). Four hundred and thirteen (208 men and 205 women) university students taking elective psychology courses at Middle East Technical University were given a scale including items about FTORR, romantic relationship satisfaction, and attitudes toward gender stereotypes about romantic relationships. All the participants were then involved in a heterosexual romantic relationship. Multiple regression results showed that for the women, attitudes toward men's assertiveness and men's dominance in relationships were more important predictors of FTORR than relationship satisfaction. For the men, attitudes toward men's assertiveness and romantic relationship satisfaction were important predictors of FTORR, but attitude toward men's dominance was not a predictor of FTORR. Women were more future oriented in their ongoing romantic relationships than were men. Finally, participants who were highly satisfied with their relationships scored higher on FTORR than those who were less satisfied.     

Disentangling the belief in God and cognitive rigidity/flexibility components of religiosity to predict racial and value-violating prejudice: A Post-Critical Belief Scale analysis

Past research indicates that being religious is associated with prejudice toward racial and value-violating out-groups. However, this past research treated religiosity as a unidimensional construct without taking into account how different components of religiosity—belief in a higher power and the rigidity/flexibility of religious beliefs—are associated with measures of prejudice. Two studies examined the relationship between these two components of religiosity, as measured by the Post-Critical Beliefs Scale, and racial (African Americans, Arabs) and value-violating prejudices (atheists, gay men). As the flexibility of religious beliefs increased (literal vs. symbolic dimension), attitudes toward racial and value-violating out-groups became more positive (Study 1). As belief in God strengthened (exclusion vs. inclusion of transcendence dimension), attitudes toward value-violating out-groups became more negative. Study 2 demonstrated that these two components of religiosity fully mediated the relationship between general religiosity and prejudice toward African Americans, Arabs, and gay men and partially mediated the relationship between religiosity and prejudice toward atheists. Results are discussed in light of reexamining the conclusion that simply being religious is associated with prejudice.
