Theory of collective mind

Theory of mind research has traditionally focused on the ascription of mental states to a single individual. Here, we introduce a theory of collective mind: the ascription of a unified mental state to a group of agents with convergent experiences. Rather than differentiation between one's personal perspective and that of another agent, a theory of collective mind requires perspectival unification across agents. We review recent scholarship across the cognitive sciences concerning the conceptual foundations of collective mind representations and their empirical induction through the synchronous arrival of shared information. Research suggests that representations of a collective mind cause psychological amplification of co-attended stimuli, create relational bonds, and increase cooperation, among co-attendees.

A Design Framework of Medical Wayfinding Signs for the Elderly: Based on the Situational Cognitive Commonness

Older people in China have a poor understanding of hospital signage. To address this problem, in this study, we combined the theories of situated cognition and cognitive commonness in order to introduce the three main factors that affect the generation of situational cognitive commonness: composition of the situation, familiarity, and concreteness. We used these theories to construct a methodological framework for the design of geriatric hospital wayfinding signs that were based on situational cognitive commonness. The design of nine healthcare signs for Chinese national standards were used as examples in the study. First, users who were familiar with medical scenarios were asked to draw concrete cognitive conception graphics for the purposes of individual wayfinding targets from both physical and social situations. Next, we coded and grouped the generated graphics based on their situational features in order to extract groups of representative common graphics. Finally, we reorganized the common graphics and developed concrete designs, which were tested by the judgment test. The wayfinding signs designed according to the methodological framework of this study effectively improved the understanding of hospital signage among older Chinese people. This study took geriatric hospital wayfinding signs as the examples to provide a feasible theoretical basis and research reference for symbol design.

Social Influence and Autobiographical Recall: Shared Reality and Epistemic Trust Shape Perceptions of Autobiographical Events

Two experiments studied the evaluative adaptation process at the outset of a communication event to examine how autobiographical memory could be shaped by audience attitude, shared reality, and epistemic trust. Experiment 1 found that audience attitude influenced communicator perceptions of their own autobiographical memories and attitudes toward the memory topic. These effects were more pronounced when communicators experienced a shared reality with their audience. Experiment 2 found that epistemic trust in the audience increased shared reality with the audience, which in turn led to greater audience-congruent memory bias in which communicators had memory perceptions and attitudes that were evaluatively consistent with the attitudes of their audience. This project underscores the prevalence of social influence processes in autobiographical recall and identifies how processes that occur at the initial stages of interpersonal communication (i.e., perceived audience attitude, trust, and shared reality) can influence how individuals construe their own life events.

Shared Reality Can Reduce Stressor Reactivity

When a person faces a stressor alongside someone else, do they get more or less stressed when the other person agrees that the situation is stressful? While an equally stressed partner could plausibly amplify stress by making the situation seem more real and worthy of distress, we find that social validation during co-experienced stressors reduces reactivity. Specifically, the psychological experience of shared reality calms some people down. In Study 1, 70 undergraduate females who jointly faced a stressful event with someone else reported feeling less anxious when the other person felt the same way about the stressor, relative to when the other person appraised the situation in the opposite way or provided no indication of their appraisal. These findings were reflected in participants' physiological reactivity, especially in the parasympathetic nervous system. In Study 2, we generalize these findings to co-experienced stressors in the daily lives of 102 heteronormative romantic couples in the New York City area. In line with tend-and-befriend theory, we found that shared reality during co-experienced stressors reduced anxiety for almost all females (99% of the sample) and for a minority of males (42% of the sample). Together, these findings unify major theories in health and social psychology by implying that shared reality reduces stressor reactivity, and that this effect is partially moderated by sex.

Shared Reality Effects of Tuning Messages to Multiple Audiences

Our study explores how communicating with audiences who hold opposite opinions about a target person can lead to a biased recall of the target's behaviors depending on whom a shared reality is created with. By extending the standard “saying-is-believing” paradigm to the case of two audiences with opposite attitudes toward a target person, we found that communicators evaluatively tune their message to the attitude of each audience. Still, their later recall of the target's behavior is biased toward the audience's attitude only for the audience with whom they created a shared reality. Shared reality creation was manipulated by receiving feedback that, based on the communicator's message, an audience was either able (success) or unable (failure) to successfully identify the target person, with the former creating a shared reality. These results highlight the importance of shared reality creation for subsequent recall when communicating with multiple audiences on a topic.

Agency and Identity in the Collective Self

Contemporary research on human sociality is heavily influenced by the social identity approach, positioning social categorization as the primary mechanism governing social life. Building on the distinction between agency and identity in the individual self ("I" vs. "Me"), we emphasize the analogous importance of distinguishing collective agency from collective identity ("We" vs. "Us"). While collective identity is anchored in the unique characteristics of group members, collective agency involves the adoption of a shared subjectivity that is directed toward some object of our attention, desire, emotion, belief, or action. These distinct components of the collective self are differentiated in terms of their mental representations, neurocognitive underpinnings, conditions of emergence, mechanisms of social convergence, and functional consequences. Overall, we show that collective agency provides a useful complement to the social categorization approach, with unique implications for multiple domains of human social life, including collective action, responsibility, dignity, violence, dominance, ritual, and morality.

Shared Reality: From Sharing-Is-Believing to Merging Minds

Humans are fundamentally motivated to create a sense of shared reality—the perceived commonality of inner states (feeling, beliefs, and concerns about the world) with other people. This shared reality establishes a sense of both social connection and understanding the world. Research on shared reality has burgeoned in recent decades. We first review evidence for a basic building block of shared-reality creation: sharing-is-believing, whereby communicators tune their descriptions to align with their communication partner’s attitude about something, which in turn shapes their recall. Next, we describe recent developments moving beyond this basic building block to explore generalized shared reality about the world at large, which promotes interpersonal closeness and epistemic certainty. Together, this body of work exemplifies the synergy between relational and epistemic motives. Finally, we discuss the potential for another form of shared reality—shared relevance—to bridge disparate realities.

Multiple Shared Realities: The Context Sensitivity of the Saying-Is-Believing Effect

People adjust how they talk about someone depending on whether their audience likes or dislikes that person. When they do so, they end up recalling the person more positively or negatively afterwards. This is known as the saying-is-believing effect, and it shows how tuning communication to an audience's attitudes and beliefs shapes one's memories. But people navigate a rich social world where they talk about the same person to different audiences with different attitudes. The current research shows that people's representations change as they do so, thus demonstrating the context sensitivity of the saying-is-believing effect. The typical saying-is-believing procedure—read about a person, describe her to others who like/dislike her, and then recall the original information—was adapted to fit multiple audiences with opposing attitudes. Results show that the same communicators recall the same person differently as a function of the audience context.

The Impact of Mixed Emotions on Creativity in Negotiation: An Interpersonal Perspective

Creativity is critical to organizational success. Understanding the antecedents of creativity is important. Although there is a growing body of research on how (mixed) emotions affect creativity, most of the work has focused on intrapersonal processes. We do not know whether contrasting emotions between interacting partners (i.e., interpersonal mixed emotions) have creative consequences. Building on information processing theories of emotion, our research proposes a theoretical account for why interpersonal mixed emotions matter. It hypothesized that mixed- (vs. same-) emotion interactions would predict higher collective creative performance. We tested the hypothesis in two-party integrative negotiations (105 dyads). We manipulated negotiators' emotional expressions (angry-angry, happy-happy, angry-happy dyads) and measured the extent to which they generated creative solutions that tapped into hidden integrative potential in the negotiation for a better joint gain. The results overall supported the hypothesis: (i) there was some evidence that mixed-emotion dyads (i.e., angry-happy) performed better than same-emotion dyads; (ii) mixed-emotion dyads, on average, achieved a high level of joint gain that exceeded the (non-creative) zero-sum threshold, whereas same-emotion dyads did not. The findings add theoretical and actionable insights into our understanding of creativity, emotion, and organization behavior.

Audience tuning effects in the context of situated and embodied processes

This review provides an overview of the research on communication and the 'Saying is Believing' paradigm in the context of different perspectives on communication. The process of 'audience tuning' is shaped by a variety of situated factors in contexts that affect the communicators' confidence in their message. The overwhelming common denominator is that the combination of features that create ambiguity yields the optimal condition for the formation of shared realities. I conclude with an argument that the implied invariance of memory processes in shared reality work needs to be more attentive to the regulatory function of memories driving the expression of shared realities.

Existential isolation and I-sharing: Interpersonal and intergroup implications

I-sharing, or believing one has the same in-the-moment experience as another person, constitutes a specific way in which people may share reality. I-sharing research underscores its significance for interpersonal and intergroup outcomes. I-sharing fosters liking for people who differ from us in objective and sometimes important ways, and counteracts robust tendencies to favor ingroup members and dehumanize outgroup members. Research and theory indicate that existential isolation-feeling alone in one's experience-explains the potency of I-sharing, insofar as people with high levels of existential isolation are especially drawn to those with whom they have reason to believe they I-share. Recent findings are reviewed, followed by a discussion of the clinical implications of the work.

Shared reality as collective closure

We draw on the theory of lay epistemics to understand how universal processes of knowledge formation drive the emergence, and determine the consequences of shared reality in groups. In particular, we highlight the role in these processes of the need for cognitive closure and credible epistemic authorities. Whereas the former construct explains why people seek a shared reality, the latter clarifies who the reality is shared with. In this connection, we review relevant bodies of empirical evidence that bear on the epistemic underpinnings of shared reality phenomena.

How shared reality is created in interpersonal communication

Communication is a key arena and means for shared-reality creation. Most studies explicitly devoted to shared reality have focused on the opening part of a conversation, that is, a speaker's initial message to an audience. The aspect of communication examined by this research is the evaluative adaptation (tuning) of the messages to the audience's attitude or judgment. The speaker's shared-reality creation is typically assessed by the extent to which the speaker's evaluative representation of the topic matches the audience-tuned view expressed in the message. We first review research on such audience-tuning effects, with a focus on shared-reality goals and conditions facilitating the generalization of shared reality. We then review studies using other paradigms that illustrate factors of shared-reality creation in communication, including mere message production, grounding, validation responses, and communication about commonly known information (including stereotypes) in intragroup communication. The different lines of research reveal the potency, but also boundary conditions, of communication effects on shared reality.

Romantic relationships as shared reality defense

A model of meaning maintenance in relationships is proposed to explain how relationships function to regulate threats to shared systems of meaning posed by life's capricious and unexpected events. This model assumes that people flexibility compensate for unexpected events in the world by affirming the expected in their relationship and compensate for unexpected events in the relationship by affirming the expected in the world. Supportive evidence is reviewed that reveals how people in more or less satisfying relationships flexibly maintain a sense of life's meaning in the face of unexpected events.

Shared reality in interpersonal relationships

Close relationships afford us opportunities to create and maintain meaning systems as shared perceptions of ourselves and the world. Establishing a sense of mutual understanding allows for creating and maintaining lasting social bonds, and as such, is important in human relations. In a related vein, it has long been known that knowledge of significant others in one's life is stored in memory and evoked with new persons-in the social-cognitive process of 'transference'-imbuing new encounters with significance and leading to predictable cognitive, evaluative, motivational, and behavioral consequences, as well as shifts in the self and self-regulation, depending on the particular significant other evoked. In these pages, we briefly review the literature on meaning as interpersonally defined and then selectively review research on transference in interpersonal perception. Based on this, we then highlight a recent series of studies focused on shared meaning systems in transference. The highlighted studies show that values and beliefs that develop in close relationships (as shared reality) are linked in memory to significant-other knowledge, and thus, are indirectly activated (made accessible) when cues in a new person implicitly activate that significant-other knowledge (in transference), with these shared beliefs then actively pursued with the new person and even protected against threat. This also confers a sense of mutual understanding, and all told, serves both relational and epistemic functions. In concluding, we consider as well the relevance of co-construction of shared reality n such processes.
