Social network composition and attitude strength: Exploring the dynamics within newly formed social networks

Recent evidence suggests that people who are embedded within attitudinally congruent social networks have stronger attitudes than those embedded in attitudinally diverse networks. The current research examines the causal processes responsible for this relation. Two studies capitalized on naturally occurring experiments whereby college students are quasi-randomly assigned to social contexts containing varying levels of attitudinal diversity. Replicating past research, individuals in attitudinally diverse social networks exhibited less resistance to attitude change and less attitude stability than those in more attitudinally congruent networks. Although there was evidence of attitude projection and selective network construction, neither of these processes could account for the relation between social network composition and attitude strength. These findings corroborate and extend previous results, reinforcing the notion that the social context in which people are embedded has important implications for the durability of their attitudes.     

Reconstruction of Adoption Issues: Delineation of Five Phases Among Adult Adoptees

Five adoption‐reconstruction phases were identified in narratives of 100 adoptees ages 35 to 55 years. Phases ranged from no awareness of adoption issues (Phase 1) to acute awareness accompanied by anger, resentment, and sadness about adoption (Phase 3) to a sense of peace and acceptance (Phase 5). Consistent quantitative and qualitative differences were found among adoptees at the 5 phases on multiple measures of functioning.     

Number-of-features effects and semantic processing

Participants list many semantic features for some concrete nouns (e.g., lion) and fewer for others (e.g., lime; McRae, de Sa, & Seidenberg, 1997). Pexman, Lupker, and Hino (2002) reported faster lexical decision and naming responses for high number of features (NOF) words than for low-NOF words. In the present research, we investigated the impact of NOF on semantic processing. We observed NOF effects in a self-paced reading task when prior context was not congruent with the target word (Experiment 1) and in a semantic categorization task (concrete vs. abstract; Experiment 2A). When we narrowed our stimuli to include high- and low-NOF words from a single category (birds), we found substantial NOF effects that were modulated by the specificity of the categorization task (Experiments 3A, 3B, and 3C). We argue that these results provide support for distributed representation of word meaning.     

Openness to attitude change as a function of temporal perspective

Three studies investigated the impact of temporal perspective on people's dominant social goals and explored the implications of these goals for openness to attitude change. Participants who perceived time as limited expressed social preferences in accordance with emotion-regulation goals (Study 1), were more prone to modify their attitude to bring it into line with the attitude of an anticipated social partner (Study 2), and were more likely to go along with peer consensus opinion on a campus issue (Study 3) than were participants who perceived time as expansive. These studies demonstrate that perception of time plays a vital role in motivating social goals within the persuasion context.     

Attitude importance and the accumulation of attitude-relevant knowledge in memory

People who attach personal importance to an attitude are especially knowledgeable about the attitude object. This article tests an explanation for this relation: that importance causes the accumulation of knowledge by inspiring selective exposure to and selective elaboration of relevant information. Nine studies showed that (a) after watching televised debates between presidential candidates, viewers were better able to remember the statements made on policy issues on which they had more personally important attitudes; (b) importance motivated selective exposure and selective elaboration: Greater personal importance was associated with better memory for relevant information encountered under controlled laboratory conditions, and manipulations eliminating opportunities for selective exposure and selective elaboration eliminated the importance-memory accuracy relation; and (c) people do not use perceptions of their knowledge volume to infer how important an attitude is to them, but importance does cause knowledge accumulation.     

Imitation of conditional discriminations in pigeons (Columba livia)

In the present experiments, the 2-action method was used to determine whether pigeons could learn to imitate a conditional discrimination. Demonstrator pigeons (Columba livia) stepped on a treadle in the presence of 1 light and pecked at the treadle in the presence of another light. Demonstration did not seem to affect acquisition of the conditional discrimination (Experiment 1) but did facilitate its reversal of the conditional discrimination (Experiments 2 and 3). The results suggest that pigeons are not only able to learn a specific behavior by observing another pigeon, but they can also learn under which circumstances to perform that behavior. The results have implications for proposed mechanisms of imitation in animals.     

The impact of feedback semantics in visual word recognition: number-of-features effects in lexical decision and naming tasks

The notion of feedback activation from semantics to both orthography and phonology has recently been used to explain a number of semantic effects in visual word recognition, including polysemy effects (Hino & Lupker, 1996; Pexman & Lupker, 1999) and synonym effects (Pecher, 2001). In the present research, we tested an account based on feedback activation by investigating a new semantic variable: number of features (NOF). Words with high NOF (e.g., LION) should activate richer semantic representations than do words with low NOF (e.g., LIME). As a result, the feedback activation from semantics to orthographic and phonological representations should be greater for high-NOF words, which should produce superior lexical decision task (LDT) and naming task performance. The predicted facilitory NOF effects were observed in both LDT and naming.     

Gender Differences in Mother-toddler and Father-toddler Verbal Initiations and Responses during a Caregiving and Play Context

Contextual variations in mother-child and father-child verbal communication were examined among 80 U.S. families from Kansas who were predominately Caucasian (85%) and middle-class. There were 41 girls and 39 boys between 15- and 18-months-old observed with their mothers and fathers in separate play and caregiving laboratory situations. Parent and child behaviors were coded for verbal initiation and response strategies. MANOVA’s revealed more differences between mother’s and father’s verbal communication strategies in the play context than the caregiving context. Boy’s and girl’s verbal communication was relatively similar across contexts. The interactions between gender and context are discussed in relation to gender role development in the family.     

Mother–child and father–child mutuality in two contexts: consequences for young children's peer relationships

This study examines the role that context plays in links between relative balance, or mutuality in parent–child interaction and children's social competence. Sixty‐three toddlers and their parents were observed in a laboratory play session and caregiving activity (i.e. eating snack). Mutuality was operationalised as the relative balance in (a) partners' compliance to initiations, and (b) partners' expression of positive emotion. Caregivers rated children's social competence with peers, and children's prosocial and aggressive behaviour with peers was observed in their childcare arrangement. Contextual differences were observed in the manifestation of parent–child mutuality, with both mother–child and father–child dyads displaying higher mutual compliance scores in the play context than in the caregiving context. Father–child dyads also displayed higher levels of shared positive emotion during play than during the caregiving context. There were no differences in a way that parent–child mutuality during play and caregiving was associated with children's social competence with peers. Overall, the results suggest that parent–child mutuality is a quality of parent–child interaction that has consistent links to children's peer competence regardless of the context in which it occurs.
