Social influences on parental and nonparental responses toward pups in virgin female prairie voles (Microtus ochrogaster)

Pair-bonded prairie voles (Microtus ochrogaster) are biparental after the birth of pups. However, whereas most adult virgin males are parental, most virgin females are not. In 6 experiments, influences on the parental behavior of virgin female prairie voles were examined. It was found that (a) young virgin females were more maternal than older females, (b) the postweaning sex ratio of cage-mates did not affect females' responses to pups, (c) females raised to adulthood with their parents and younger siblings present were highly parental, (d) 48-hr exposure to pups beginning at weaning increased some aspects of later maternal responding, (e) rearing to adulthood with the parents even in the absence of younger siblings also increased females' maternal responding, and (f) the increase was seen only if both parents were present. Continued parental presence promotes alloparental behavior, possibly important if daughters do not disperse from the natal nest.     

Evaluations of older and younger adult speakers: influence of communication effectiveness and noise

University students (N = 96) performed 3 communication tasks presented to them either by young men (mean age = 26 years) or by older men (mean age = 77 years). In counterbalanced order, students heard speakers in 3 message conditions (effective, ineffective, and noise). The messages of older men and the older men themselves were evaluated less positively than were younger men. In line with the hypothesis of age-biased behavioral interpretation, older adults speaking effectively were not accorded the same evaluative benefits over their less effective guises, especially on competence ratings, as were younger speakers. Furthermore, the noise condition was predictably more detrimental to ratings of the older speakers, who were more vulnerable to generalized negative affect.     

Social comparisons with siblings made by adolescents with a learning difficulty

Social comparisons and the family environment are important antecedents of self-esteem. In this study the self-esteem and perceptions of stigma of 50 adolescents with a mild-moderate learning difficulty were measured. The self-esteem and stigma scores were factor-analysed to produce five factors: Positive self; Social competence; Being different; Anxiety; and Work competence. Social comparisons made by the adolescents between themselves and their siblings were also measured. Most adolescents 'preferred' (chose more often and gave high scores to) older same-sex siblings while younger opposite-sex siblings were the least preferred (were chosen less often and derogated). An explanation for these findings is suggested in terms of defensive social comparisons due to the loss of self-esteem in having a younger sibling ‘overtake’ the adolescent on developmental milestones, and in the tendency for non-handicapped pre-pubescent children to derogate the opposite sex during gender identity formation. This explanation is supported by the finding that the adolescents with younger siblings scored higher on the Anxiety factor than those who compared themselves with older siblings. Those with younger same-sex siblings were the most anxious. There was also a tendency for adolescents with siblings to score lower on one of the factors than adolescents with no sibling. The discussion raises the questions of how to deal with social comparisons within the family and how to talk to the child with mild learning difficulties about his or her handicap.     

Brothers and Sisters: Nature and Importance of the Adult Bond

The closeness, importance and nature of adult sibling relationships were examined in a preliminary study. Forty-eight males and 87 females aged 17 to 84 years were subjects. Each completed a questionnaire about themselves and relationships with their siblings. Results indicated that females were closer to their siblings than were males, same-sex sibling pairs were closer than cross-sex pairs, and younger subjects were closer to their siblings than were older subjects. The nature of the relationship between siblings was very positive with few negative feelings reported. Sex, sexual makeup of the sibling pair, and age also affected the nature of the relationship and topics discussed between siblings.     

Siblings of disabled children: Birth order and age-spacing effects

Whereas older siblings of children with congenital disability have lived their earliest years in a normal family environment, younger siblings, especially those in a close age-spacing relationship, were born into families marked by the presence of a disabled child. In this paper, 237 siblings of disabled children are compared to 248 siblings from a random sample of families to examine whether the early family environment of siblings of disabled children, as indexed by relative birth order and age-spacing, has a unique influence on psychological functioning. The findings partially confirmed the expected relationships: Younger male siblings, specifically those in close age-spacing relationship to the disabled child, scored higher on psychological impairment than older male siblings. Among female siblings, a similar influence was not in evidence: Younger female siblings were psychologically better off than older female siblings and their age-spacing was not significantly related to psychological functioning. However, the results suggest that siblings' later response to early life experience may be sex-contingent, with males demonstrating interpersonal aggression and females experiencing depressive-anxious feelings.This study was supported by grants from the Cleveland Foundation and the C. S. Mott Foundation. The helpful comments of Joanne C. Gersten are gratefully acknowledged.     

Ineffective Schools as Organizational Reactions to Stress

Educational research has identified effective schools in terms of characteristics associated with high student achievement, and conversely, schools lacking these characteristics are often conceived as ineffective schools. In this article, I propose that organizational stress responses create the conditions that make schools effective or ineffective. In other words, low achievement does not make schools ineffective but rather organizational behavior associated with stress creates and perpetuates school ineffectiveness, including low achievement. Drawing on the threat-rigidity thesis and open systems theory, hypotheses regarding how groups and organizations respond to stress were tested using demographic and achievement data for students attending elementary schools, in addition to survey data obtained from students (N= 18,189), principals (N= 75), and parents (N= 13,768). Using cluster analysis, schools were grouped and described in terms of the schools stress level (student populations requiring more resources for learning), school adaptations to stress (emphases on varied school internal processes), and school output (student achievement). To lessen input from the external environment, schools experiencing more stress had less permeable bound- aries, as indicated by parent reports of less school involvement and less positive school climate. Schools experiencing more stress also had more internal disruption, as indicated by less consensus among parents and students regarding school internal processes and by more principal changes. However, in such schools, there was little evidence of more control over school internal processes in terms of principals self-reported behavior and student and parent perceptions of school order and discipline, and teacher support of learning. Results call for a better understanding of school ineffectiveness in terms of organizational adaptations to stress and points at which to intervene for more effective school adaptation and functioning.     

Sibling violence and agonistic interactions among middle adolescents

Two hundred seventy-two high school juniors and seniors were surveyed regarding their experiences as victims and perpetrators of sibling violence and agonistic interactions with their closest-spaced siblings. Findings support earlier reports that siblings engage in a variety of violent acts directed toward one another and that there are few differences between males and females as to the extent of the behaviors. Subjects reported experiences of negative physical and verbal interactions less frequently than did younger subjects in previous studies, suggesting the need to further examine age-related differences in sibling violence. Discussion focuses on the implications of the present findings and direction for future studies in this area.     

“I'm an ogre so I'm very hungry!” “I'm assistant ogre”: The Social Function of Sibling Imitation in Early Childhood

Siblings' imitative behaviors were investigated in 39 middle‐class dyads during six 90‐min home sessions at both Time 1 (M age: older sibling = 4.4 years; younger sibling = 2.4 years) and Time 2 (2 years later). Although younger siblings imitated most often at T1 and T2, older siblings' imitation increased proportionally over time in comparison to younger siblings. Findings highlight the affiliative nature of imitation that occurred during reciprocal play interactions, via positive responses, and the content of the imitation. Finally, age was controlled by comparing first‐born siblings aged 4 at T1 to second‐born siblings aged 4 at T2. Findings demonstrated that sibling imitation had distinct characteristics despite the age match and partner effects. Sibling imitation is a dynamic, interactive social behavior and may be a powerful source of learning for young children.

Highlights

• The role of sibling imitation in ongoing play in early childhood is highlighted.
• Sibling imitation is a dynamic and affiliative behavior that promotes interaction during play.
• Naturalistic observations of sibling imitation document that it is a powerful source of learning for young children.

     

Coital behaviors, attitudes, and knowledge of students who experience early coitus

The purpose of this study was to investigate coital behavior, contraceptive practices, and attitudinal and knowledge differences between "early coital initiators" (subjects having initial coitus at 16 years or younger) and "late coital initiators" (subjects having initial coitus from 17 to 20 years of age). Data were compiled from the results of a questionnaire administered to 929 students enrolled in personal health courses at 14 colleges and universities. The sample used for analysis included only the never-married coitally experienced males and females aged 20 and older (N = 396). The results suggested that late coital initiators: were more effective contraceptors during initial coitus; had more committed relationships with their initial sex partners; engaged in more discussion about and planning for contraceptive use; and used more authoritative and reliable sources for contraceptive information than their younger counterparts. Both groups scored very low on basic knowledge questions concerning fertility, contraception, and sexually transmitted diseases. These results mandate greater public concern and involvement to delay early coital experiences and prevent unprotected sexual intercourse.     

Predictors of Children's Emotional Distress in a Mother-Absent Situation: Implications for Caregiving Research

Although many factors have been found to be associated with caregiving behavior among preschool-age siblings, few studies have considered the older child's emotional responses to the distress of a younger sibling in the mother's absence. In this study, the authors considered both individual and family factors that predict older and younger sibling distress in a mother-absent situation designed to elicit caregiving behavior. For both older and younger siblings, the strongest predictor of distress following the mother's departure was distress in the other sibling, suggesting the importance of situational factors. Individual and family factors, however, were also found to predict child distress. Among older siblings, shy and sociable temperaments were associated with greater distress during the mother's absence. Higher levels of parenting stress were found to be associated with less distress among both older and younger siblings in the mother-absent situation. Results are discussed in terms of individual and family environment influences on the sibling relationship.

A child-centred exploration of the relevance of family and friends to theory of mind development

Theory of Mind (ToM) is said to develop at around 4 years old. But some studies suggest it develops considerably earlier than this, with others suggesting it develops much later. Although several recent studies have found that social factors (like gender, family size, number of siblings, and number of friends) can impact on ToM, other studies contradict those findings. We wondered whether addressing several procedural issues and ensuring the task concerns real protagonists in real time, would bear on the above issues. Here, 114 children of 3-6 years completed four ToM tasks incorporating controls from experimental psychology, including randomly varying the order of ToM and non-ToM questions across participants. Now, children passed ToM tasks from around 5 years old, rather than 4 years or earlier. Girls did not develop ToM any earlier than boys. There was clear correlational evidence for the older-sibling effect and effects of friends but no reliable effects of nuclear or extended family. However, when these factors were set in the context of one another, the sibling effect was driven by a negative influence from younger siblings (as opposed to older siblings) and the friends effect was driven by friends at school (as opposed to friends at home). Finally, "friends" was a stronger predictor than siblings but memory (a cognitive factor) and age (a maturational factor) were the strongest predictors of all.     

Depression Mixed with Anxiety,Somatization, and Disordered Eating: Relationship with Gender-Role-Related Limitations Experienced by Females

In several previous studies, females who reported that they felt limited by responses to their gender, or viewed their mothers as having been limited in this way, exhibited higher prevalence compared to other females or to males of depression accompanied by anxiety, somatic symptoms such as headaches, disordered eating, and poor body image/preference for thinness (“anxious somatic depression”), but not higher prevalence of depression unaccompanied by these other symptoms (“pure depression”). In this study of high school students, females whose mothers scored high on a scale measuring their feelings of having been limited by traditional gender roles reported much higher prevalence than other females of anxious somatic depression, but not higher prevalence of pure depression. Mothers' reports of depression were not related to daughters' anxious somatic depression.     

GENDER COMPARISONS OF MATHEMATICS ATTITUDES AND AFFECT

This article reports the complex results of meta-analyses of gender differences in attitudes and affect specific to mathematics. Overall, effect sizes were small and were similar in size to gender differences in mathematics performance. When differences exist, the pattern is for females to hold more negative attitudes. Gender differences in self-confidence and general mathematics attitudes are larger among high school and college students than among younger students. Effect sizes for mathematics anxiety differ depending upon the sample (highly selected or general). One exception to the general pattern is in stereotyping mathematics as a male domain, where males hold much more stereotyped attitudes ( d = -.90). While affect and attitudes toward mathematics are not the only influences on the development of gender differences in mathematics performance, they are important, and both male and female affect and attitudes should be considered in conjunction with other social and political influences as explanations.     

Secondary attachments and adolescent self concept

This study examined the popular notion that crushes or secondary attachments to celebrity figures are an important aspect of self-concept development during adolescence. In a repeated measures design, 79 male and female 5th, 8th, and 11th graders and college sophomores completed a set of personality scales, first describing themselves and later, describing the favorite celebrity. Repeated measures multivariate analyses of variance (MANOVA) analysis of self-object congruence revealed no significant main or interaction effects for the type of attachment, gender, or age of subject. Significant within subject effects were obtained for the repeated measures factor (self-object congruence). Overall, students perceived their attachment objects to be more agentic, yet less expressive and emotionally vulnerable than themselves. MANOVA analyses indicated that males and older students perceived their attachment objects to be higher in agency than expressivity, whereas females and younger students perceived their attachment objects to be higher in expressivity than agency. These data indicate that the function served by secondary attachments in the development of self-concept may be quite similar for adolescent males and females.     

Childhood play and adolescent leisure preferences: Associations with gender typing and the presence of siblings

Childhood play and adolescent leisure preferences were solicited from a sample of 168 predominately white undergraduate students, who also completed the Bem Sex Role Inventory (BSRI; Bem, 1974) and provided ratings of the amount of time spent in play and leisure with same- and opposite-sex siblings. Higher Femininity (F) scores were found among those females who gave higher ratings of interaction with female siblings. The BSRI measures were also predicted by play and leisure preferences for strongly gender-stereotyped activities. Amount of interaction with same- and opposite-sex siblings was associated with activity preferences for both sexes. There was evidence of more sex-stereotyped preferences being given by those with same sex siblings and fewer by those with opposite sex siblings. The results are discussed in terms of the possible influences of siblings upon play and leisure preferences and the differing developmental pathways of male and female sex roles.     

Perceived influences on career choices of eleventh graders: Sex,SES, and ethnic group comparisons

The project Sex-Role Values and Career Decision Making was conducted to examine the responses of eleventh-grade high school students to sex-role-related values and to relate these responses to their educational and occupational aspirations. The concern of the present article is the influence of Sex, SES (socioeconomic status), and ethnicity on the reasons students give for their career choices. While students' responses were found to be generally similar across Sex, SES, and ethnic groups, the results indicated that females were significantly less likely than males to mention practical considerations, money, prestige, or status as elements in their career decisions, and more likely to mention helping others and personal achievement. The implications of these sex differences for sex equality in the career selection process are considered.The project reported on in this article was performed pursuant to a grant from the National Institute of Education, Department of Health, Education and Welfare.

Types of Social Connectedness and Loneliness: the Joint Moderating Effects of Age and Gender

Drawing on Maslow’s Theory, this study aims to examine how the interaction between age and gender moderates the associations between types of social connectedness (i.e., parents, siblings, friends, and teachers) and loneliness. The results of multigroup analyses using a sample of 618 school-going adolescents showed that the effect of social connectedness on loneliness varies across different subgroups of age and gender. Specifically, parent connectedness predicts lower loneliness for older males. For older females, parent connectedness showed the same pattern of reduced loneliness. Furthermore, younger males and younger females were getting less lonely with having sibling connectedness. On the other hand, the findings have failed to find significant relationship between friend and teacher connectedness and loneliness across four subgroups. Overall, the results provide further evidence of the protective effect of family connectedness on loneliness, and for informing under what conditions the effect is strengthened or weakened.     

The More the Merrier? Sibling Composition and Early Manifestations of Theory of Mind in Toddlers

Sibling relationships are argued to offer a rich social context for the development of young children’s theory of mind (ToM). There is evidence that the presence of siblings, particularly older siblings, may promote preschoolers’ ToM, but it has not been investigated among toddlers. This study evaluated differences in early manifestations of ToM between toddlers in different sibling compositions: 1) without a sibling, 2) with younger siblings only, and 3) with older siblings only. The sample included 227 toddlers who completed 2 tasks assessing their understanding of discrepant desires and visual perspectives. Results indicated that only children and those who had older siblings did not differ from each other on either task. However, on both tasks, toddlers with younger siblings performed significantly more poorly compared with those with older siblings. Moreover, children with younger siblings demonstrated poorer visual-perspective understanding compared with only children. It may be critical to take siblings’ birth order into account when investigating their respective effects on each other’s ToM, especially in toddlerhood.     

Birth order and personality: Some empirical findings and a biobehavioral theory

The birth-order variables assessed included sex and number of siblings, assignment to 2- or 3-child family for separate sample analysis, family position as appropriate to given sample, spacing effect—was the birth of the second child spaced 4 years or more after the first child—dominance relationships in the family, sex of nearest siblings, sex of other siblings as appropriate, whether raised by both original parents, whether raised by foster parent(s). The personality variables assessed included sociability, anxiety, dominance, superego, phlegmatic temperament, involvement, self-regard and other scales measured by the new Howarth Personality Questionnaire. Samples of 50 for the 2-child families and 58 for the 3-child families were analyzed and it was found that: (a) in the 2-child families eldest children were less cooperative than younger, that those reporting dominance by another sibling were higher in state anxiety and this also applied to the younger of the pair, that those spaced in birth order were less afraid of being socially unacceptable, that those raised by both parents were higher in involvement; (b) in the 3-child families those dominated by a sibling, regardless of position, had more hypochondriac symptoms (a sign of anxiety), and that those spaced in birth order showed less cooperativeness. A biobehavioral theory to encompass biological-hormonal spacing effects and dominance as well as other intrafamilial behaviors was proposed.
