Are parents' gender schemas related to their children's gender-related cognitions? A meta-analysis.

Meta-analyses were conducted of 43 articles (with 48 different samples) investigating the relationship between parents' gender schemas and their offspring's gender-related cognitions. The parents' offspring ranged in age from infancy to early adulthood. Offspring measures included gender self-concept, gender attitudes toward others, gender-related interests, and occupational attitudes. Overall, a small but meaningful effect size (r = .16) indicated a significant and positive correlation between parent gender schemas and offspring measures. Specifically, parents with more traditional gender schemas were more likely than parents with more nontraditional schemas to have offspring with gender-typed cognitions about themselves or others. In addition, the magnitudes of observed effect sizes were influenced by particular moderator variables, including type of parent gender schema (gender self-concept vs. gender attitudes toward others), type of offspring gender-related cognitions, parent gender, offspring gender, offspring age, and publication characteristics. The results are cautiously interpreted as suggesting a possible influence of parents on the development of their children's gender-related thinking.

How Ras-related proteins talk to their effectors

More and more effectors for the Ras-related protein superfamily are being discovered and it is emerging that these GTP-binding proteins interact with more than one effector to generate more than one cellular signal. Atomic details for the interaction of Rap/Ras with one of the effectors, the protein kinase c-Raf-1, have recently become available by X-ray structure analysis. The implications for the specificity of the signal transduction pathway, and how the GTP-dependent switch mechanism modulates the interaction with effectors will be discussed here, using Ras as a paradigm.     

A gender difference in visual-spatial ability in 4-year-old children: effects on performance of a kinesthetic acuity task

Eighty 4-year-old children (40 boys and 40 girls) were tested on a kinesthetic acuity test (KAT), half in the presence of extra visual-spatial cues and half in the absence of these cues. All subjects were also tested on a three-dimensional block design test, a measure of visual-spatial ability. It was found that for both sexes KAT performance in the presence of the extra cues was superior to performance in their absence. In the presence of the cues boys performed significantly better than girls but when the extra cues were absent, the gender difference disappeared. There was a significant gender difference in performance on the block design test and a strong correlation between block design and KAT (with extra cues) performance for both sexes. When KAT cues were reduced, this correlation was substantially reduced. The results indicated that the gender difference in KAT performance found previously in the presence of extra visual-spatial cues was due to differential use of these cues rather than to a gender difference in kinesthetic acuity.     

Flexible and compressed workweek schedules: A meta-analysis of their effects on work-related criteria.

Meta-analytic techniques were used to estimate the effects of flexible and compressed workweek schedules on several work-related criteria (productivity/performance, job satisfaction, absenteeism, and satisfaction with work schedule). In general, the effects of both schedules were positive. However, the effects of both flextime and compressed workweek schedules were different across the outcome criteria (e.g., compressed workweek schedules did not significantly affect absenteeism). Thus, the level of positive impact associated with either schedule is dependent on the outcome criterion under consideration. Further, several variables were found to be moderators of flexible work schedules. For example, highly flexible flextime programs were less effective in comparison to less flexible programs, and the positive benefits of flextime schedules were found to diminish over time.

Identification accuracy of children versus adults: a meta-analysis

Identification accuracy of children and adults was examined in a meta-analysis. Preschoolers (M = 4 years) were less likely than adults to make correct identifications. Children over the age of 5 did not differ significantly from adults with regard to correct identification rate. Children of all ages examined were less likely than adults to correctly reject a target-absent lineup. Even adolescents (M = 12-13 years) did not reach an adult rate of correct rejection. Compared to simultaneous lineup presentation, sequential lineups increased the child-adult gap for correct rejections. Providing child witnesses with identification practice or training did not increase their correct rejection rates. Suggestions for children's inability to correctly reject target-absent lineups are discussed. Future directions for identification research are presented.     

Training impulsive children to talk to themselves: A means of developing self-control.

Examined the efficacy of a cognitive self-instructional (SI) training procedure in altering the behavior of impulsive school children. Study I, with 15 2nd graders, employed an individual training procedure which required the impulsive child to talk to himself, initially overtly and then covertly, in an attempt to increase self-control. Results indicate that the SI group improved significantly relative to attentional and assessment control groups on the Porteus Maze Test, performance IQ on the WISC, and on a measure of cognitive impulsivity. The improved performance was evident in a 1-mo follow-up assessment. Study II, with 8 kindergartners and 7 1st graders, examined the efficacy of the components of the cognitive treatment procedure in altering the impulsive child's performance. Results indicate that cognitive modeling alone was sufficient to slow down the impulsive child's response time for initial selection, but only with the addition of SI training was there a significant decrease in errors. Treatment and research implications of modifying S's cognitions are discussed. (45 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Age effects and health appraisal: a meta-analysis

OBJECTIVE: The purpose was to clarify the effects of methodological variables in the research on age differences in self-rated health and specifically the effects of: (a) the item type used to solicit the appraisal, (b) the approach to sampling, and (c) the criteria for assembling the age groups for study. METHODS: Studies differing on these dimensions were compared using meta-analytic techniques. Seventeen usable samples were grouped according to the age comparisons--seven compared "young" and "old" samples while ten compared "young-old" and "old-old" groups. RESULTS: The results failed to support the frequently reported health optimism of old-old samples when compared with young-old. Further, the findings suggest that the item type used in eliciting the rating of health may be instrumental in the respondent's appraisal process. For instance, use of the age-comparative item tends to favor "old" groups when compared to young, whereas the global health item has an effect in the other direction. Effect size was also related to a study's sampling procedure and to the method used in assembling groups (i.e., age ranges used to represent young and old). DISCUSSION: Practical implications and areas of needed research are discussed.     

Labels and explanations in mother-child emotion talk: age and gender differentiation

Specific proteins of the apolipoprotein serum amyloid (apoSAA) family that are synthesized in large quantities during the acute, early phase of inflammation can serve as the proteinaceous precursors for amyloid fibrils. To model fibrillogenesis in such inflammatory diseases, we have used electron microscopy and X-ray diffraction to examine the structures formed by synthetic peptides corresponding in sequence to the 11 amino-terminal amino acids of murine apoSAA1, apoSAAcej, and apoSAA2 and to the 15 amino-terminal amino acids of apoSAA2. This region is reported to be the major fibrillogenic determinant of apoSAA isoforms. Both in 1 mM Tris buffer and in 35% acetonitrile, 0.1% trifluoracetic acid (ACN/TFA), all of the peptides formed macromolecular assemblies consisting of twisted, approximately 40- to 60-A-thick ribbons, which varied in width from around 40-70 A (for 11-mer apoSAA2 in Tris) up to 900 A (for the other peptides). X-ray diffraction patterns recorded from lyophilized peptides, vapor-hydrated samples, and solubilized/dried samples showed hydrogen bonding and intersheet reflections typical of a beta-pleated sheet conformation. The coherent lengths measured from the breadths of the X-ray reflections indicated that with hydration the growth of the assemblies in the intersheet stacking direction was comparable to that in the hydrogen-bonding direction, and analysis of oriented samples showed that the beta-strands were oriented perpendicular to both the long axis and the face of the assemblies. These X-ray results are consistent with the ribbon- or plate-like morphology of the individual aggregates and emphasize the polymorphic nature of amyloidogenic peptides. Our findings demonstrate that X-ray diffraction measurements on vapor-hydrated or solubilized/dried versus lyophilized, amyloidogenic peptides are a good indicator of their fibrillogenic potential. For example, from the highest to the lowest potential, the peptides examined here were ranked as: Abeta1-28 > Abeta1-40 > apoSAA1 approximately apoSAAcej > apoSAA2 > Abeta17-42. Experiments in which the three different 11-mer apoSAA isoforms were solubilized in ACN/TFA and then combined as binary mixtures showed that the ribbon morphology was not affected but that the extent of hydrogen bonding in the assemblies was substantially reduced. Our observations on the in vitro assembly of apoSAA analogs emphasize that amyloid fibril formation and morphology depend on primary sequence, length of polypeptide chain, the presence of additional fibrillogenic polypeptides, and solvent conditions.     

Children's coping strategies: Moderators of the effects of peer victimization?

Coping strategies were examined as potential moderators of the effects of peer victimization on children's adjustment. Self-report data on victimization experiences, coping strategies, and loneliness were collected on ethnically diverse 9-10-year-old children (177 girls, 179 boys). Teacher ratings of children's anxious-depressed and social problems and peer nominations of social preference were also obtained. Findings revealed that strategies such as problem solving that were beneficial for nonvictimized children exacerbated difficulties for victimized children. The effects of specific forms of coping were dependent on gender: Social support seeking buffered victimized girls from social problems but was associated with lower peer preference for victimized boys. Data also revealed the need to examine the effects of coping on multiple adjustment outcomes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Treating children who do not play or talk: Finding a pathway to intersubjective relatedness.

This article explores the application of mother-infant research and systems theory in treating children whose capacity to symbolize is severely impeded. Working with children who do not play or talk involves the creation of a transitional space to foster the development of their symbolic capacities and intersubjective relatedness. The clinical material examines the unfolding of the mother-infant patterned interaction, including ruptures without repair. Therapeutic action begins with the experience of imitation, state sharing, leading to the emergence of intersubjective relatedness. Self-with-other structures shift and transform as the child is provided with the new relational experience of finding himself or herself in the mind of the other. Ideas expressed may also apply to the treatment of silent adult patients. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Distress in couples coping with cancer: A meta-analysis and critical review of role and gender effects.

Research concerning distress in couples coping with cancer was integrated using meta-analysis and narrative critical appraisal. Individual levels of distress were determined more by gender than by the role of being the person with cancer versus that person's partner. That is, women reported consistently more distress than men regardless of their role (standardized mean difference = 0.31). The association between patient and partner distress within couples was only moderate (r = .29) but is sufficient to warrant further consideration of the notion that these couples react as an emotional system rather than as individuals. It is noteworthy that this association is not moderated by gender. With a general lack of comparison groups, the question of how much distress can be ascribed to the cancer experience cannot be answered decisively; elevations in distress are probably modest. We critically discuss these results, identify important unanswered questions, and indicate directions for future research. Attention needs to be directed toward factors other than cancer as direct influences of distress in these couples and to mediators and moderators of the cancer experience.

New trends in gender and mathematics performance: A meta-analysis.

In this article, we use meta-analysis to analyze gender differences in recent studies of mathematics performance. First, we meta-analyzed data from 242 studies published between 1990 and 2007, representing the testing of 1,286,350 people. Overall, d = 0.05, indicating no gender difference, and variance ratio = 1.08, indicating nearly equal male and female variances. Second, we analyzed data from large data sets based on probability sampling of U.S. adolescents over the past 20 years: the National Longitudinal Surveys of Youth, the National Education Longitudinal Study of 1988, the Longitudinal Study of American Youth, and the National Assessment of Educational Progress. Effect sizes for the gender difference ranged between –0.15 and +0.22. Variance ratios ranged from 0.88 to 1.34. Taken together, these findings support the view that males and females perform similarly in mathematics. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Social aspects of > 800 couples coming forward for gender selection of their children

The social characteristics of 809 couples attending a sex preselection clinic have been studied. Their ethnic origins were: Indian 57.8%, European 32.0%, Chinese 3.6% and others 6.8%. The average number of boys and girls per family was 0.09 and 2.70 respectively for couples wanting a boy, and 2.46 and 0.14 for those wanting a girl. The average age of the wives was 34.0 years. These figures were not significantly different in any ethnic subgroup. Out of all the couples, 80.6% stated that they would have had another baby even had sex preselection not been on offer; 37.5% of the couples interviewed have been treated so far. The figures among those treated are substantially the same as those for the whole group. Asian and Middle Eastern couples overwhelmingly wanted boys, whereas European couples showed a slight preference for girls. These results suggest that, given certain guidelines, sex selection is unlikely to lead to a serious distortion of the sex ratio in Britain and other Western societies, but may need careful monitoring in other parts of the world.

Labels and explanations in mother–child emotion talk: Age and gender differentiation.

Mothers' and preschoolers' emotion talk was examined for age- (2, 3, and 4 years) and gender-related patterns in the use of labels and explanations. Although labels directly refer to emotions, explanations link emotion words to causal information. Children used emotion words mainly in labels. Boys' emotion talk showed an age increase: in contrast, the youngest group of girls talked about emotion much more frequently than did same-age boys, and this high frequency remained relatively stable across age. Mothers used more explanations than labels in emotion talk to boys but used similar amounts with girls. Further, their use of labels and explanations related to individual differences in the extent to which children talked about emotion. These findings are discussed in terms of language socialization?in particular, processes related to the socialization of emotion language and gender.

Some gender effects in a brief psychotherapy.

Two studies investigated the influence of therapist gender as well as patient age and pretreatment distress level on process and outcome in a brief 12-session psychodynamic psychotherapy. Pre- and posttherapy assessments disclosed that patients treated by female therapists experienced more symptomatic improvement and reported more satisfaction with treatment than those treated by male therapists. However, patient age accounted for twice, and patient pretreatment level of disturbance more than three times, the outcome variance contributed by gender. In Study 2 female therapists were judged to arouse less negative affect in women patients and to arouse fewer interpersonal difficulties.

Task complexity as a moderator of goal effects: A meta-analysis.

Much evidence exists that supports the use of goal setting as a motivational technique for enhancing task performance; however, little attention has been given to the role of task characteristics as potential moderating conditions of goal effects. Meta-analysis procedures were used to assess the moderator effects of task complexity for goal-setting studies conducted from 1966 to 1985 (n?=?125). The reliability of the task complexity ratings was .92. Three sets of analyses were conducted: for goal-difficulty results (hard vs. easy), for goal specificity–difficulty (specific difficult goals vs. do-best or no goal), and for all studies collapsed across goal difficulty and goal specificity–difficulty. It was generally found that goal-setting effects were strongest for easy tasks (reaction time, brainstorming), d?=?.76, and weakest for more complex tasks (business game simulations, scientific and engineering work, faculty research productivity), d?=?.42. Implications for future research on goal setting and the validity of generalizing results are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
