The effect of information distribution on collaborative inhibition

Two experiments examined collaborative memory for information that was studied by all group members (shared items) and information that was studied by only a subset of group members (unshared items). In both experiments significant collaborative inhibition (reduced output of the collaborative groups relative to the pooled output of individuals) was obtained for both shared and unshared information. In Experiment 1 the magnitude of collaborative inhibition was larger for unshared items than for shared items, possibly because unshared items were less likely to be acknowledged and thus incorporated into the groups’ recall. In Experiment 2 the magnitude of collaborative inhibition for shared and unshared information was equivalent once all participants were provided with the category name associated with the shared and unshared items. The results of the experiments are discussed in relation to the retrieval strategy disruption hypothesis of collaborative inhibition and the role of social process variables, such as acknowledgement, in influencing collaborative inhibition across situations involving memory of shared and unshared information.     

Culture and gender differences in romantic jealousy

Jealousy is an intense emotion that is experienced in the context of romantic relationships. Previous research reported gender differences in ratings of jealousy over a sexual versus emotional infidelity. This study explored culture and gender differences in jealousy using a mixed methods survey design. One hundred and forty-five undergraduates from the University of Hawai‘i at Hilo participated. The Horizontal and Vertical Individualism and Collectivism Scale, Self-Report Jealousy Scale, and a modified Emotional and Sexual Jealousy Scale were used for analyses. Two hierarchical multiple regression analyses revealed that gender was a better predictor than culture in jealousy ratings involving an emotional infidelity; but culture was a better predictor for jealousy ratings involving a sexual infidelity. t-Tests also revealed that those who experienced an infidelity in the past reported significantly higher jealousy ratings and that women reported significantly higher jealousy ratings in emotional but not in sexual infidelity than men. The qualitative results revealed four dominant themes related to participant’s causal attributions of jealousy: Infidelity, Expectations of Time and Commitment, Social Media and Self-Esteem. The authors suggest that future research focus on intersexual and intrasexual differences in jealousy, as well the role social media may play in relationship expectations.     

The collaborative encoding deficit is attenuated with specific warnings

Individuals learning together do so less effectively than individuals learning alone, an effect known as the collaborative encoding deficit. In the present studies we examined whether providing participants with a warning about the collaborative encoding deficit would increase their encoding task performance, and reduce subsequent memory deficits. Across two experiments, specific warnings were beneficial for memory. Collaborating participants who were told about the collaborative encoding deficit, and who received suggestions for how to complete the encoding task, had superior memory than participants who received no warning. This benefit was not due to qualitative changes in encoding task performance, was unrelated to the type of collaboration utilised, was absent when a more general warning was utilised, and was unrelated to self-reported task motivation. Rather, specific warnings appear to protect against the collaborative encoding deficit by increasing time spent on, and attention directed to, the encoding task.     

Representing Blissymbols with a Young Child

This article describes a comparison of pencil embellishment cued, versus picture cued learning, in lhe establishment of an initial Blissymbol vocabulary. The design of the study followed N = 1 time series principles. The single subject represented an analog developmentally young individual. She was 2 years 10 months old at the commencement of the study and on a range of cognitive scales was of average ability. Within its restricted parameters, the study indicated superiority of pencil embellishment over pictures as simultaneous learning aids. Various speculative conclusions based on these findings are drawn.     

Engaging in upward and downward comparisons as a determinant of relative deprivation at work: A longitudinal study

A longitudinal study was conducted among 93 nurses to determine the role of comparing one’s performance with that of one’s colleagues in the increase versus decrease of perceived relative deprivation at work over a period of one year. Relative deprivation at T2 had increased particularly among those high in social comparison orientation (Gibbons & Buunk, 1999) who at T1 (1) more frequently engaged in upward comparisons; (2) more frequently derived positive as well as negative feelings from such comparisons; and (3) more frequently derived negative feelings from downward comparison. Moreover, engaging in downward comparison also led to an increase in perceived relative deprivation at T2. This study is one of the few to find evidence for longitudinal effects of social comparison activity, and the first to find that such effects occur only for those high in social comparison orientation.     

The Meaning of the Sperm Donor for Heterosexual Couples: Confirming the Position of the Father

In the literature, relatively little attention has been paid to the meaning of donor involvement in the intimate couple dyad. The current study aimed to enrich our understanding of couples' meaning‐making regarding the anonymous sperm donor and how they dealt with the donor involvement. Semi‐structured interviews were conducted with nine couples, who had at least one child conceived through sperm donation. Our thematic analysis showed that the donor conception was seen as a different path to create a normal family. Once the family was formed, most couples avoided talking about the donor because it was perceived as disrupting men's growing confidence in their position as father. Participants tried to confirm the position of the father to protect the family relationships. Uncertainties about how they were perceived as parents showed the continuing dominance of genetic ties within our social discourse. Participants also dealt with reminders of the donor in their daily life. Overall, they tried to manage the space taken up by the donor and to protect the position of the father. We relate our findings to literature on topic avoidance and shared obliviousness in families. For counseling practice, it could be useful to explore couples' meaning‐making about the donor as this seemed to serve family functioning.     

Observed Mother– and Father–Child Interaction Differences in Families with Medically Assisted Reproduction‐Conceived Twins and Singletons

Increased medically assisted reproduction (MAR) use to treat infertility has resulted in a growing twin birth rate. Little is known about parent–child relationships for twin relative to singleton children in middle childhood. This study fills this gap by examining parent–child relationships in 57 families with eighty 6‐ to 12‐year‐old MAR twin and singleton children using observational data (warm and supportive communication, control, and hostility). Nested ANCOVAs indicate that while mothers exhibit similar interactional behaviors toward twins and singletons, fathers have less optimum behaviors toward twins relative to singletons. Twins displayed less engaged behavior with mothers and fathers relative to singletons. Given the vitality of parent–child relationships for family and child adjustment, future studies should examine determinants and outcomes of twin–singleton relationship differences to bolster twins’ and their families’ functioning.     

儿童青少年协作促进的发展

旨在考察不同年龄的个体, 在不同回忆序列和学习材料上协作促进的发展情况。采用3(回忆序列:协作—个人—个人〔CII〕、个人—协作—个人〔ICI〕、个人—个人—个人〔III〕)× 5(年龄:9、11、14、17、20)× 2(材料:图片、文字)的被试间设计。结果发现:(1)各年龄个体在CII和ICI两种回忆序列上均出现了协作促进, 且两种序列条件下被试的最终个人回忆成绩无差异;(2)另外, 17岁个体的协作促进量显著高于9岁、11岁、14岁和20岁, 其他各年龄之间无差异;(3)图片和文字的协作促进量无差异。这说明小组协作回忆的顺序对协作促进没有太大影响, 17岁个体协作促进的效果最好。     

Collaborative narration of the past and extraversion

We propose that collaborative narration is a process in which narrative identity develops, and we examine individual differences in extraversion in such narration. Two studies are presented: retrospective and experience sampling episodes of collaborative narration, the first with self-defining memories, the second with everyday narration. Across both studies, extraversion was associated with an increased frequency in collaborative narration. This finding was not explained by the ‘talkativeness’ item in the extraversion measures. Further, more extraverted people shared their self-defining memories with more people and were more comfortable sharing than less extraverted people, the impact of extraversion was specific to mutual reminiscence in everyday narration, and mutual reminiscence was more enjoyable for those who are more extraverted than introverted. Implications from these data for understanding individual differences in identity and narrative development are discussed.     

Home Environment and Self‐Efficacy Beliefs among Native American,African American,and Latino Adolescents

Context helps determine what individuals experience in the settings they inhabit. Context also helps determine the likelihood that those experiences will promote adaptive development. Theory suggests likely interplay between various aspects of home context and development of ideas about self that influence patterns of development for children. This study addressed relations between two aspects of home life (companionship and investment, modeling and encouragement) and three types of self‐efficacy beliefs (enlisting social resources, independent learning, self‐regulatory behavior) considered important for long‐term adaptive functioning. The study focused on three groups of minority adolescents (Native American, African American, Latino). Relations were examined using regression models that also included four aspects of household risk that often hinder the development of self‐efficacy. Although findings varied somewhat across the three groups, significant relations emerged between the two domains of home life examined and self‐efficacy beliefs in all three groups, even controlling for overall household risk. Companionship and investment appeared particularly relevant for African American adolescents, while modeling and encouragement appeared particularly relevant for Native American adolescents. Both were relevant for Latino adolescents.
