Affect Control Theories: A Double Special Issue in Honor of David R. Heise

We introduce this two-part special issue that celebrates David Heise and his pathbreaking theories: affect control theory (ACT), affect control theory of the self (ACTS), and affect control theory of institutions (ACTI). These interlocking, multi-level, mathematically based theories explain a range of social processes, including impression formation, social interaction, trait and mood attributions, emotional experiences, emotion management, and identity adoption, and they do so in multiple languages and cultures. The 15 articles in this two-part issue test, apply, and develop the theories in new and innovative ways. After briefly summarizing each theory and Bayesian affect control theory (BayesACT), we highlight the key findings from each of the articles that follow.

Relationship Seekers Versus Relationship Selectors: Influence of Residential Mobility on How to Evaluate Others

The present study examined the effect of residential mobility on impression formation. In the study, participants were first engaged in a residential mobility priming task where they were asked to imagine and describe either frequent moving life (high-mobility condition) or less frequent moving life (low-mobility condition). They then evaluated their attitudes toward four types of target persons: competent vs. incompetent and warm vs. cold. As a result, in the high-mobility condition, the effect of competence was observed only when participants evaluated a warm person, whereas in the low-mobility condition, it appeared only when participants evaluated a cold person. The potential influence of individual residential mobility on the relationship formation is also discussed.

Reduced Perceived Trustworthiness during Face Mask Wearing

To curb the diffusion of the novel coronavirus (SARS-CoV-2), governments worldwide have introduced different policies, including lockdowns, social distancing, and mandatory mask wearing. Face mask wearing, especially, has an impact on the formation of first impressions, given that when meeting someone for the first time, individuals rely on the only available piece of information, the newly met person’s aesthetic appearance, in order to make initial estimations of other traits, such as competence, intelligence, or trustworthiness. However, face mask wearing affects the aesthetic appearance of an individual, creating uncertainty which, in turn, has been reported to reduce others’ perceived trustworthiness. In this paper, the influence of face mask wearing on strangers’ perceived trustworthiness and aesthetic appearance is assessed to verify the impact of this policy on impression formation. Participants (N = 71) have been instructed to assess the trustworthiness and the aesthetic appearance of a selection of 96 images depicting individuals of different ages (children, adults, and older adults), gender (men and women), and ethnicity (Asians or Caucasians). Participants were randomly divided into two groups: an experimental group and a control group. Participants in the experimental group (N = 38) rated faces of individuals wearing a face mask, while participants in the control group rated the same faces but in the absence of a face mask. Images were presented in random order. For each face, participants were asked to rate the aesthetic appearance and perceived trustworthiness of the stranger on two different 100-point Likert scales. Results demonstrate that (i) the correlation between perceived trustworthiness and aesthetic appearance is not affected by the presence of a face mask, and (ii) age, but not ethnicity and gender, influences the magnitude of differences in perceived trustworthiness levels during mask wearing.

Preprint: When Does Group Information Influence the Automatic and Deliberate Judgment of Individual Group Members?

According to some impression formation theories, when people perceive an individual member of a social group, the information about the group is activated more spontaneously and easily than information specific to the individual. Therefore, the judgment of individual group members might be more sensitive to group information (relatively to individuating information) the more automatic (fast, unintentional, and effortless) the judgment is. We tested this premise with a minimalistic impression formation paradigm that provided evaluative information about eight individuals and assigned them to two novel groups. In one group, three members behaved positively, and one member behaved negatively. In the other group, three members behaved negatively and one positively. In seven main experiments and 12 auxiliary experiments, we examined whether people’s automatic (but not deliberate) judgment of the atypical group members would be determined by the valence of the typical behavior in the group (group information) or the valence of the typical behaviors of that person (individuating information). Individuating information had a larger effect on automatic and deliberate evaluation than group information. The relative effect of group information (vs. individuating information) was slightly stronger on automatic than on deliberate judgment. This discrepancy increased when we increased the salience of group membership upon judgment, or when participants belonged to one of the groups. Our findings suggest that, inherently, automatic judgment of individuals is only slightly more biased than deliberate judgment by group information. Yet, under circumstances that are common in everyday life, that bias increases in automatic but not in deliberate judgment.

Effect of the Opponent’s Appearance on Interpersonal Cognition that Affects User-to-User Relationship in Virtual Whole-Body Interaction

People infer the internal characteristics (attitude, intent, thoughts, ability, relationship, etc.) of others (interpersonal cognition, IC) from the impressions they form from the personality or attributes of those others (impression formation). Studies premised on interpersonal communication in a seated condition have confirmed that, regardless of whether the communication is in the real world or in a media environment, the appearance of the other person affects IC and the outcome of the communication. People also develop relationships based on impressions or images of the other party. The psychological relationship manifests in physical relationships, that is, the relative positions of the body or the movement. In this study, we evaluate the effects of the appearance of the opponent’s avatar on the players’ IC in whole-body interaction taking place in a virtual reality (VR) space. Moreover, we examine the feasibility of constructing a method of changing the players’ relationship in interpersonal interactions that accompany the control and interference of the entire body, “whole-body interaction,” by manipulating their appearances. In this study, we selected the party game Twister as a case model of whole-body interaction and developed a system that allows users to play Twister in VR space. Using this system environment, we conducted an experiment to evaluate the players’ IC based on the gender and realism of the opponent’s avatar. The results showed that differences in the appearance of the opponent’s avatar affected the IC of male players. We also indicated that changes in IC observed in the experiment can affect the players’ relationship, thus identifying issues that must be resolved in order to realize the method.

Older and Younger Adults Perform Similarly in an Iterated Trust Game

In social contexts, aging is typically associated with a greater reliance on heuristics, such as categorical information and stereotypes. The present research examines younger and older adults’ use of individuating and age-based categorical information when gauging whether or not to trust unfamiliar targets. In an adaptation of the iterated Trust Game, participants had to predict the cooperative tendencies of their partners to earn economic rewards in first encounters – in a context in which they knew nothing about their partners, and across repeated interactions – in a context in which they could learn the individual cooperative tendency of each partner. In line with previous research, we expected all participants to rely on stereotypes in first encounters, and progressively learn to disregard stereotypes to focus on individuating behavioral cues across repeated interactions. Moreover, we expected older participants to rely more on social categories than younger participants. Our results indicate that overall, both the elderly and the young adopted an individuating approach to predict the cooperative behaviors of their partners across trials. However, older adults more consistently relied on gender (but not age) stereotypes to make cooperation decisions at zero acquaintance. The impact of context, motivation, and relevance of categorical information in impression formation is discussed.

Spontaneous State Inferences

Perceivers routinely draw inferences about others from their behavior in an attempt to make sense of the world. Previous research has established that spontaneous inferences include stable characteristics such as traits and a number of variable person-related concepts such as goals, intentions, and motivations. The current research investigated the occurrence of more general spontaneous state inferences. In a series of four preregistered studies (N = 883), we adapted two established experimental paradigms frequently used in spontaneous social inference research to the investigation of spontaneous trait and state inferences. In Studies 1 and 2, we observed evidence for the occurrence of spontaneous state inferences from state-implying statements. In Studies 3 and 4, we observed the simultaneous occurrence of spontaneous trait and state inferences from statements that allowed for both inferences. In a fifth study (N = 97), we provide evidence that people represent states and traits as functionally different: Participants judged the likelihood of behavioral repetition higher when the same behavior was related to a trait-inference than a state inference. The observation of multiple simultaneous spontaneous inferences in the current research suggests that further theory building regarding the underlying mechanisms and processes of spontaneous impression formation in person perception from behavior is warranted.

EXPRESS: Estimating the Effects of Trait Knowledge on Social Perception

Research in social cognition has predominantly investigated perceptual and inferential processes separately, however real-world social interactions usually involve integration between person inferences (e.g., generous, selfish) and the perception of physical appearance (e.g., thin, tall). Therefore, in the current work, we investigated the integration of different person-relevant signals, by estimating the extent to which bias in one social information processing system influences another. Following an initial stimulus-validation experiment (Experiment 1, N=55), two further pre-registered experiments (Experiments 2, N=55 & 3; N=123) employed a priming paradigm to measure the effects of extraversion-diagnostic information on subsequent health and body-size judgements of a target body. The results were consistent across both priming experiments and supported our predictions: compared to trait-neutral control statements, extraversion-diagnostic statements increased judgements of health and decreased those of body size. As such, we show that trait-based knowledge does not only influence mappings towards similar types of person judgments, such as health judgments. Rather, even a brief re-configuration of trait-space alters mappings towards non-trait judgments, which are based on body size and shape. The results complement prior neuroimaging findings that showed functional interactions between the body-selective brain regions in the ventral visual stream and the theory of mind network when forming impressions of others. Therefore, we provide a functional signature of how distinct information processing units exchange signals and integrate information in order to form impressions. Overall, the current study underscores the value of behavioural work in complementing neuroscience when investigating the role and properties of functional integration during impression formation. Additionally, it stresses the potential limitations of an over-reliance on studying separate systems in isolation.

Influences of Social Distancing and attachment styles on the strength of the Halo Effect

The Halo Effect is a widely studied phenomenon that interests multiple disciplines. The relationship between Aesthetics Appearance and perceived Trustworthiness has especially gathered the attention of social scientists. While experimental works compared the strength of the Halo Effect in different situations (e.g. different genders’ faces), little is known about the stability of the Halo. During the COVID-19 pandemic, we have been urged to distance ourselves from others. Similar suggestions may alter the relationship between Aesthetic Appearance and Perceived Trustworthiness. Moreover, previous works reported that individuals’ attachment styles affected their emotional responses to the pandemic. Individuals’ attachment styles may influence the magnitude of change of the Halo. Here we investigate how priming (Social Distancing or Contact with others) affects the strength of the Halo Effect, with respect to individuals’ attachment styles. Participants (N = 298) rated the Aesthetics and Perceived Trustworthiness of strangers’ faces (N = 96) presented twice, before and after the presentation of a prime. Results revealed that individuals’ attachment styles affect the strength of the Halo. However, we found no evidence supporting the fact that different attachment styles lead to differences in the magnitude of changes after priming. Results help shed light on how attachment styles influence individuals’ impression formation.
