Group size and social interactions are associated with calling behavior in Carolina chickadees (Poecile carolinensis)

The complexity of a social group may influence the vocal behavior of group members. Recent evidence in Carolina chickadees, Poecile carolinensis, indicated that one component of social complexity, group size, influenced the complexity of the "chick-a-dee" call, a vocalization functioning in social cohesion. Individuals in larger social groups used calls with greater information than did individuals in smaller social groups. Here, the authors review this earlier work, and describe a recent study indicating that social interactions between females and males within female-male pairs of chickadees were associated with rates of chick-a-dee call production in the males. Together, these studies suggest that the nature and complexity of social interactions among members of chickadee social groups influence chick-a-dee calling behavior.     

Interpersonal perception in a social context

Interpersonal perception among well-acquainted individuals in a social context was studied. High acquaintance was expected to provide perceivers with a large sample of target behaviors across situations. In turn, memory for acquaintances should be organized by social group and personality characteristics, as predicted by the social context-personality index theory. Differentiation of the target's traits in memory should produce a target effect on perception that is stronger than the perceiver effect. Furthermore, evidence for accuracy, meta-accuracy, independence of self- and other-perception, and reciprocity of affect were anticipated. A social relations analysis of data from a multiple-interaction, reciprocal design was used to study these phenomena. At the individual level, analyses indicated that perceptions of targets were determined primarily by target characteristics and secondarily by perceiver construction of the judgment. Also, perceivers judged targets as targets judged themselves, and targets knew in general how perceivers viewed them. Self- and other-perceptions were largely independent. Surprisingly, we did not observe dyadic meta-accuracy.     

Information theoretical approaches to chick-a-dee calls of Carolina chickadees (Poecile carolinensis)

One aim of this study was to apply information theoretical analyses to understanding the structural complexity of chick-a-dee calls of Carolina chickadees, Poecile carolinensis. A second aim of this study was to compare this structural complexity to that of the calls of black-capped chickadees, P. atricapillus, described in an earlier published report (Hailman, Ficken, & Ficken, 1985). Chick-a-dee calls were recorded from Carolina chickadees in a naturalistic observation study in eastern Tennessee. Calls were analyzed using approaches from information theory, including transition probability matrices, Zipf's rules, entropies, and information coding capacities of calls and notes of calls. As described for black-capped chickadees, calls of Carolina chickadees exhibited considerable structural complexity. Most results suggested that the call of Carolina chickadees is more structurally complex than that of black-capped chickadees. These findings add support to the growing literature on the complexity of this call system in Paridae species. Furthermore, these results point to the feasibility of detailed cross-species comparative analyses that may allow strong testing of hypotheses regarding signal evolution.     

Behavioral change and consistency across contexts

The degree to which behavior changes across situations is often conflated with the cross-situational consistency of individual differences. The current study assesses the extent of behavioral change and consistency, the relationship between them, and variables associated with behaviors’ differing patterns of change and consistency. Two hundred fifty-six participants were observed in three different, three-person interactions. In line with previous research, behaviors showed a great deal of both change and consistency. Behavioral change across situations was unrelated to the degree to which individual differences in these same behaviors were maintained, demonstrating that behavioral consistency does not imply lack of situational adaptation. Behaviors rated as relatively broad and as relatively automatic showed more consistency; behaviors rated as relatively controlled showed more change.     

Social complexity can drive vocal complexity: group size influences vocal information in Carolina chickadees

One hypothesis to explain variation in vocal communication in animal species is that the complexity of the social group influences the group's vocal complexity. This social-complexity hypothesis for communication is also central to recent arguments regarding the origins of human language, but experimental tests of the hypothesis are lacking. This study investigated whether group size, a fundamental component of social complexity, influences the complexity of a call functioning in the social organization of Carolina chickadees, Poecile carolinensis. In unmanipulated field settings, calls of individuals in larger groups had greater complexity (more information) than calls of individuals in smaller groups. In aviary settings manipulating group size, individuals in larger groups used calls with greater complexity than individuals in smaller groups. These results indicate that social complexity can influence communicative complexity in this species.     

Attitudes in social context: A social identity perspective

Research on attitudes and attitude phenomena occupies a central place in social psychology, but tends to focus mainly on cognitive, intra-individual, and interpersonal dimensions. The normative, group membership, and identity dimensions of attitudes tend to attract less attention. This article approaches attitudes from the perspective of research on group processes, intergroup relations, and social identity, and conceptualises attitudes and attitude phenomena in terms of their group normative properties and dynamics. Our perspective is explicitly framed and focused by contemporary social identity theory—a theory that has a great deal to contribute to attitude research, but often does not talk directly about attitudes. We discuss attitudinal influence and change, how people perceive normative attitudes, and how attitudes relate to action.     

Smiling virtual agent in social context

A smile may communicate different communicative intentions depending on subtle characteristics of the facial expression. In this article, we propose an algorithm to determine the morphological and dynamic characteristics of virtual agent's smiles of amusement, politeness, and embarrassment. The algorithm has been defined based on a virtual agent's smiles corpus constructed by users and analyzed with a decision tree classification technique. An evaluation, in different contexts, of the resulting smiles has enabled us to validate the proposed algorithm.

Coping strategies in Chinese social context

The present study examined whether the scale called Coping Strategies in Chinese Social Context (CSCSC) developed in this paper is better at predicting individual mental health than the COPE Scale, which focuses on 'active-passive' coping. Two hundred and 51 university students were recruited and measured on the CSCSC, COPE and five mental health inventories. The results demonstrated that the CSCSC predicted mental health better than the COPE. 'Active-prosocial' and 'passive-prosocial' are two suitable coping strategies, whereas 'passive-antisocial' is not a suitable coping strategy. Studies exploring coping processes in Chinese culture should consider social interactions and connection with others as a significant aspect of coping.     

Behavioral confirmation in social interaction: From social perception to social reality

A perceiver's actions, although based upon initially erroneous beliefs about a target individual may channel social interaction in ways that cause the behavior of the target to confirm the perceiver's beliefs. To chart this process of behavioral confirmation, we observed successive interactions between one target and two perceivers. In the first interaction, targets who interacted with perceivers who anticipated hostile partners displayed greater behavioral hostility than targets whose perceivers expected nonhostile partners. Only when targets regarded their actions as reflections of personal dispositions did these behavioral differences in hostility persevere into their subsequent interactions with naive perceivers who had no prior knowledge about them. Theoretical implications of the behavioral confirmation construct for social perception processes are discussed.     

Behavioral and social cognitive processes in preschool children's social dominance

This longitudinal, naturalistic study addressed behavioral and social cognitive processes implicated in preschool children's social dominance. In the first objective, we examined the degree to which peer aggression, affiliation, and postaggression reconciliation predicted social dominance across a school year. Consistent with predictions, all three predicted dominance early in the year while only affiliation predicted dominance later in the year, suggesting that aggression, affiliation, and reconciliation were used to establish social dominance where affiliation was used to maintain it. In the second, exploratory, objective we tested the relative importance of social dominance and reconciliation (the Machiavellian and Vygotskian intelligence hypotheses, respectively) in predicting theory of mind/false belief. Results indicated that social dominance accounted for significant variance, beyond that related to reconciliation and affiliation, in predicting theory of mind/false belief status. Results are discussed in terms of specific behavioral and social cognitive processes employed in establishing and maintaining social dominance.     

Behavioral manifestations of social support: a microanalytic investigation

This study was designed to examine the specific interpersonal behaviors that convey support from one person to another. Subjects were 41 undergraduate students who completed a general measure of perceived social support and, subsequently, kept daily records of their social interactions and stressful experiences for 14 days. In addition, they completed a brief depressive mood measure (DACL; Lubin, 1981) each day. Results showed that behaviors reflecting emotional support and informational support occurred as a specific response to stressful life events. Although esteem support was expressed with equal frequency in the presence and absence of stress, it was especially effective in preventing depressive reactions to stressful events. Subjects who perceived themselves as having high levels of perceived social support were more frequently the recipients of helping behaviors following stressful events than those low in perceived support. Perceived social support was only predictive of helping behaviors on days on which at least one stressful event occurred. The total number of helping behaviors received following stressful events was a significant negative predictor of level of depressive mood, although one helping behavior was associated with higher levels of depression. Results are interpreted within the framework of the buffering model of social support.     

Behavioral components of social competence in females

This study examined behavioral components used by peers to judge heterosocial competence in females. Thirty-five female undergraduates participated in two interactions with a naive male partner. Judges provided global ratings for female subjects on attractiveness, skill, anxiety, guidance, listening, and smoothness of response. Behavioral counts of smiles, gestures, self-manipulations, talk time, and gaze were also obtained from the videotapes of the interactions. Although many specific behaviors correlated with judgments of social competency, talk time and gaze best predicted social competency in women. Implications of the results and future research directions are discussed.This study was conducted as part of the first author's master's thesis while a student at Purdue University.     

Young children's difficulty with inhibitory control in a social context1

Abstract: The authors’ prior research has documented that young children's behaviors in the Dimensional Change Card Sorting (DCCS) task can be influenced by their observation of another person performing the task and has suggested that young children committed perseverative errors in a social context. The present study explored whether children who committed perseverative errors in the social context also committed perseverative errors in the standard DCCS task. Three‐ and 4‐year‐old children were given the standard DCCS and the observation version of the DCCS, and the relationship between them was examined. The results showed that the correlation between these two tasks was significant. Furthermore, 4‐year‐old children displayed more difficulty in the observation version than in the standard DCCS, whereas 3‐year‐olds did not. The results are discussed in terms of the development of inhibitory control and social cognition.     

Power and social context in superior-subordinate interaction

Power differences are thought to interfere with superiors' interaction with subordinates. However, it is also argued that superiors with considerable power are most supportive of their subordinates. To explore these opposing positions, 90 undergraduates became managers with either high or low power who believed their goals were cooperatively, individualistically, or competitively related to their subordinate. Results support the hypothesis that social context affects how superiors use their power to interact with subordinates. High- and low-power superiors in cooperation had positive expectations, interacted constructively, restated the task, responded to requests for assistance, and developed a positive relationship compared to high- and low-power superiors in individualistic and competitive situations. In addition, only the high-power superiors in cooperation used their expertise to give direct aid to the subordinate. Results indicate that in cooperation superiors are likely to use their power constructively; however, in competitive and individualistic contexts, superiors are apt to fail to use their resources to facilitate subordinate performance. Results were also interpreted as suggesting that it is not so much the extent of superiors' power but the social context that affects their use of power and interaction with subordinates.
