Being in the minority boosts in-group love:Explanations and boundary conditions.

People appreciate members of their in-group, and they cooperate with them-tendencies we refer to as in-group love. Being a member of a minority (vs. majority) is a common experience that varies both between groups in a context and within a group between contexts, but how does it affect in-group love? Across six studies, we examined when and why .

Validating a brief measure of four facets of social evaluation.

Five studies (N = 7972) validated a brief measure and model of four facets of social evaluation (friendliness and morality as horizontal facets; ability and assertiveness as vertical facets). Perceivers expressed their personal impressions or estimated society's impression of different types of targets (i.e.

Political rule (vs. opposition) predicts whether ideological prejudice is stronger in U.S. conservatives or progressives.

People see societal groups as less moral, warm, and likable if their ideology is more dissimilar to the ideology of the self (i.e., ideological prejudice).

Unconstrained Descriptions of Facebook Profile Pictures Support High-Dimensional Models of Impression Formation.

Dominant models of impression formation focus on two fundamental dimensions: a horizontal dimension of warmth/communion/trustworthiness and a vertical dimension of competence/agency/dominance. However, these models have typically been studied using theory-driven methods and stimuli of restricted complexity. We used a data-driven approach and naturalistic stimuli to explore the latent dimensions underlying >300,000 unconstrained linguistic descriptions of 1,000 Facebook profile pictures from 2,188 participants.

Perceived Power Polarizes Moral Evaluations.

We show an interactive effect of perceiver-target similarity in ideological beliefs and target power on impressions of target morality. Consistent with prior research, perceivers rated targets with dissimilar ideologies as less moral than targets with similar ideologies, but this difference in ratings was magnified for powerful targets relative to less powerful targets. We argue that these results emerged because perceivers expected similar-ideology, powerful (vs.

Differentiation in social perception: Why later-encountered individuals are described more negatively.

According to the cognitive-ecological model of social perception, biases toward individuals can arise as by-products of cognitive principles that interact with the information ecology. The present work tested whether negatively biased person descriptions occur as by-products of cognitive differentiation. Later-encountered persons are described by their distinct attributes that differentiate them from earlier-encountered persons.

Reminders undermine impressions of genuine gratitude.

While reminders can help by encouraging prosocial behaviors, we propose that they can also hurt. Across 10 studies, most of which focus on reminders to express gratitude, we find that reminders interfere with impressions of genuine prosociality. Whether people are reminded subtly (Studies 1a and 6-8) or blatantly (Studies 2-5) to express gratitude, the reminder is perceived to put social pressure on the potential thanker, making reminded thankers seem less genuine and less likable than spontaneous thankers.

Quantification of protein abundance and interaction defines a mechanism for operation of the circadian clock.

The mammalian circadian clock exerts control of daily gene expression through cycles of DNA binding. Here, we develop a quantitative model of how a finite pool of BMAL1 protein can regulate thousands of target sites over daily time scales. We used quantitative imaging to track dynamic changes in endogenous labelled proteins across peripheral tissues and the SCN.

Cryptochrome proteins regulate the circadian intracellular behavior and localization of PER2 in mouse suprachiasmatic nucleus neurons.

The ∼20,000 cells of the suprachiasmatic nucleus (SCN), the master circadian clock of the mammalian brain, coordinate subordinate cellular clocks across the organism, driving adaptive daily rhythms of physiology and behavior. The canonical model for SCN timekeeping pivots around transcriptional/translational feedback loops (TTFL) whereby PERIOD (PER) and CRYPTOCHROME (CRY) clock proteins associate and translocate to the nucleus to inhibit their own expression. The fundamental individual and interactive behaviors of PER and CRY in the SCN cellular environment and the mechanisms that regulate them are poorly understood.

Relational versus structural goals prioritize different social information.

People gather information about others along a few fundamental dimensions; their current goals determine which dimensions they most need to know. As proponents of competing social-evaluation models, we sought to study the dimensions that perceivers spontaneously prioritize when gathering information about unknown social groups. Because priorities depend on functions, having relational goals (e.

Identifying the dimensions of secrets to reduce their harms.

How does the content of secrets relate to their harms? We identified a data-driven model (across five empirical steps), which suggested that secrets are generally seen to differ in how immoral, relational, and profession/goal-oriented they are (Study 1). The more a secret was consensually perceived to be immoral, relational, and profession/goal-oriented, the more that secret was reported to evoke feelings of shame, social connectedness, and insight into the secret, respectively. These three experiences independently predicted the extent to which the secret was judged as harmful to well-being (Studies 2a-c and 3).

Explaining Negativity Dominance without Processing Bias.

In a recent study, Shin and Niv explain both negativity and positivity biases in social evaluations as a function of the diversity and low frequency of events. We discuss why negative information is indeed more diverse and less frequent, and highlight the implications beyond social evaluations.

Navigating the social world: Toward an integrated framework for evaluating self, individuals, and groups.

Social evaluation occurs at personal, interpersonal, group, and intergroup levels, with competing theories and evidence. Five models engage in adversarial collaboration, to identify common conceptual ground, ongoing controversies, and continuing agendas: Dual Perspective Model (Abele & Wojciszke, 2007); Behavioral Regulation Model (Leach, Ellemers, & Barreto, 2007); Dimensional Compensation Model (Yzerbyt et al., 2005); Stereotype Content Model (Fiske, Cuddy, Glick, & Xu, 2002); and Agency-Beliefs-Communion Model (Koch, Imhoff, Dotsch, Unkelbach, & Alves, 2016).

The ABC of society: Perceived similarity in agency/socioeconomic success and conservative-progressive beliefs increases intergroup cooperation.

The dimensions that explain which societal groups cooperate more with which other groups remain unclear. We predicted that perceived similarity in agency/socioeconomic success and conservative-progressive beliefs increases cooperation across groups. Self-identified members ( = 583) of 30 society-representative U.

Adversarial alignment enables competing models to engage in cooperative theory building toward cumulative science.

Crises in science concern not only methods, statistics, and results but also, theory development. Beyond the indispensable refinement of tools and procedures, resolving crises would also benefit from a deeper understanding of the concepts and processes guiding research. Usually, theories compete, and some lose, incentivizing destruction of seemingly opposing views.

The differential similarity of positive and negative information - an affect-induced processing outcome?

People judge positive information to be more alike than negative information. This good-bad asymmetry in similarity was argued to constitute a true property of the information ecology (Alves, H., Koch, A.

A Cognitive-Ecological Explanation of Intergroup Biases.

People often hold negative attitudes toward out-groups and minority groups. We argue that such intergroup biases may result from an interaction of basic cognitive processes and the structure of the information ecology. This cognitive-ecological model assumes that groups such as minorities and out-groups are often novel to a perceiver.

The "common good" phenomenon: Why similarities are positive and differences are negative.

Positive attributes are more prevalent than negative attributes in the social environment. From this basic assumption, 2 implications that have been overlooked thus far: Positive compared with negative attributes are more likely to be shared by individuals, and people's shared attributes (similarities) are more positive than their unshared attributes (differences). Consequently, similarity-based comparisons should lead to more positive evaluations than difference-based comparisons.

How Orthogonal Are the Big Two of Social Perception? On the Curvilinear Relation Between Agency and Communion.

Humans make sense of their social environment by forming impressions of others that allow predicting others' actions. In this process of social perception, two types of information carry pivotal importance: other entities' communion (i.e.

Why Good Is More Alike Than Bad: Processing Implications.

Humans process positive information and negative information differently. These valence asymmetries in processing are often summarized under the observation that 'bad is stronger than good', meaning that negative information has stronger psychological impact (e.g.

The ABC of stereotypes about groups: Agency/socioeconomic success, conservative-progressive beliefs, and communion.

Previous research argued that stereotypes differ primarily on the 2 dimensions of warmth/communion and competence/agency. We identify an empirical gap in support for this notion. The theoretical model constrains stereotypes a priori to these 2 dimensions; without this constraint, participants might spontaneously employ other relevant dimensions.

A general valence asymmetry in similarity: Good is more alike than bad.

The density hypothesis (Unkelbach, Fiedler, Bayer, Stegmüller, & Danner, 2008) claims a general higher similarity of positive information to other positive information compared with the similarity of negative information to other negative information. This similarity asymmetry might explain valence asymmetries on all levels of cognitive processing. The available empirical evidence for this general valence asymmetry in similarity suffers from a lack of direct tests, low representativeness, and possible confounding variables (e.

A density explanation of valence asymmetries in recognition memory.

The density hypothesis states that positive information is more similar than negative information, resulting in higher density of positive information in mental representations. The present research applies the density hypothesis to recognition memory to explain apparent valence asymmetries in recognition memory, namely, a recognition advantage for negative information. Previous research explained this negativity advantage on the basis of valence-induced affect.

Response category width as a psychophysical manifestation of construal level and distance.

The present research suggests that people adjust their mental response scales to an object's distance and construal level. People make use of wider response categories when they judge distant and abstract as compared with close and concrete stimuli. Across five experiments, participants worked on visual and verbal estimation problems (e.

Fluency and positivity as possible causes of the truth effect.

Statements' rated truth increases when people encounter them repeatedly. Processing fluency is a central variable to explain this truth effect. However, people experience processing fluency positively, and these positive experiences might cause the truth effect.
