Given the evolutionary significance of survival, the mind might be particularly sensitive (in terms of strength and speed of reaction) to stimuli that pose an immediate threat to physical harm. To rectify limitations in past research, we pilot-tested stimuli to obtain images that are threatening, nonthreatening-negative, positive, or neutral. Three...

Dual-process models of attitudes distinguish between implicit and explicit processes in which the valence (i.e., positivity or negativity) of a stimulus influences judgments and behavior toward the stimulus. Developing parallel to the dual-process literature has been a threat detection literature suggesting that the mind is preferentially attuned t...

Physically threatening objects are negative, but negative objects are not necessarily threatening. Moreover, responses elicited by threats to physical harm are distinct from those elicited by other negatively (and positively) valenced stimuli. We discuss the importance of the threat versus valence distinction for implicit measurement both in terms...

Mouse-tracking facilitates exploration of the mental processes underlying decision making. As the cognitive system works to settle on a decision, response competition manifests in the motor movements of the hand, bringing the mouse relatively closer to one alternative versus the other. Many metrics provide insight into decision-making processes by...

The Dual Implicit Process Model (March et al., 2018a) distinguishes the implicit processing of physical threat (i.e., “can it hurt or kill me?”) from valence (i.e., “do I dislike/like it?”). Five studies tested whether automatic anti-Black bias is due to White Americans associating Black men with threat, negative valence, or both. Studies 1 and 2 a...

De Neys argues against assigning exclusive capacities to automatic versus controlled processes. The dual implicit process model provides a theoretical rationale for the exclusivity of automatic threat processing, and corresponding data provide empirical evidence of such exclusivity. De Neys's dismissal of exclusivity is premature and based on a lim...

1. How people experience nature influences their attitudes and actions towards it. Having had a negative encounter with an animal may facilitate avoidance and freezing responses which may encourage negative feelings towards it and the environment in which it is found. Animals associated with fear, such as snakes, are often the victims of hunting an...

Three pilot studies (Ntotal = 832) revealed that people held more positive attitudes toward targets wearing protective face masks. Therefore, we examined whether knowledge of this self-presentational benefit would increase people's intentions to wear face masks. Participants (N = 997) were randomly assigned to read a passage about the COVID-19 pand...

How well can social scientists predict societal change, and what processes underlie their predictions? To answer these questions, we ran two forecasting tournaments testing the accuracy of predictions of societal change in domains commonly studied in the social sciences: ideological preferences, political polarization, life satisfaction, sentiment...

Not everyone engages in COVID‐19 related preventative health behaviors (PHB; e.g., mask wearing, social distancing) despite their demonstrated effectiveness for mitigating the spread of COVID‐19. In the United States, for instance, PHBs emerged as (and remain) a partisan issue. The current work examines partisan gaps in PHB by considering both info...

Recent work suggests that good/bad out-group favoritism of Blacks for Whites may reflect positive associations with White rather than negative associations with Black. The Dual Implicit Process Model suggests that Blacks may come to associate their own group with threat, even absent a concurrent Black-negative association. This work tests this idea...

Following theories of emotional embodiment, the facial feedback hypothesis suggests that individuals’ subjective experiences of emotion are influenced by their facial expressions. However, evidence for this hypothesis has been mixed. We thus formed a global adversarial collaboration and carried out a preregistered, multicentre study designed to spe...

To answer these questions, we ran two forecasting tournaments testing accuracy of predictions of societal change in domains commonly studied in the social sciences: ideological preferences, political polarization, life satisfaction, sentiment on s...

Threat avoidance involves both detection of a threatening stimulus and reaction to it. We demonstrate with empirically validated stimuli (that are threatening, nonthreatening-negative, neutral, or positive) that threat detection is more pronounced among males, whereas threat reactivity is more pronounced among females. Why women are less efficient...

Recently, major societal events have shaped perceptions of race relations in the US. The current work argues that people’s motivations to be nonprejudiced toward Black people have changed in concert with these broader societal forces. Analyses of two independent archival datasets reveal that nonprejudiced motivations changed predictably in accordan...

A neural architecture that preferentially processes immediate survival threats relative to other negatively and positively valenced stimuli presumably evolved to facilitate survival. The empirical literature on threat superiority, however, has suffered two problems: methodologically distinguishing threatening stimuli from negative stimuli and diffe...

The role of implicit processes during police-civilian encounters is well studied from the perspective of the police. Decades of research on the “shooter bias” suggests that implicit Black-danger associations potentiate the perception of threat of Black individuals, leading to a racial bias in the decision to use lethal force. Left understudied are...

Dual-process models of cognition distinguish relatively automatic from relatively controlled processes in terms of their interactive impact on perception, judgment, and behavior. Such models have advanced explanation and prediction in a variety of domains across psychology but have yet to be comprehensively applied to the pressing societal and publ...

Objective Accurate threat appraisal is central to survival. In the case of the coronavirus pandemic, accurate threat appraisal is difficult due to incomplete medical knowledge as well as complex social factors (e.g., mixed public health messages). The purpose of this study was to evaluate the degree to which individuals accurately perceive COVID-19...

The facial feedback hypothesis suggests that an individual’s subjective experience of emotion is influenced by their facial expressions. Researchers, however, currently face conflicting narratives about whether this hypothesis is valid. A large replication effort consistently failed to replicate a seminal demonstration of the facial feedback hypoth...

Learning one is similar to a stigmatized group can threaten one’s identity and prompt disassociation from the group. What are the consequences of learning of a similarity to a stigmatized group when that similarity implies possible recategorization into the group? We investigated how learning of an immutable, recategorization implying similarity wi...

However, researchers currently face conflicting narratives about whether this hypothesis is valid. A large collaborative effort consistently failed to replicate a seminal demonstration of the facial feedback h...

Evaluative conditioning (EC) refers to a change in one's attitude toward an object based on its contiguous pairing with other positive or negative objects. EC can, in principle, occur through multiple mechanisms, some more and some less thoughtful. We argue that one relatively low-thought route through which EC produces evaluative change is implici...

We thank the commentators for such thought-provoking and insightful critiques of our target article (March, Gaertner, & Olson, this issue). Their varied theoretical orientations provided interesting analyses and challenging assessments of our dual implicit process model (DIPM). We organized our response into three sections. Some of the issues id...

Positive media depictions of Obama likely contribute to the so-called "Obama effect." However, like any attitude-object, effects of those depictions can depend on contextually positive or negative portrayals. We hypothesized that politically conservative news web sites (e.g., FoxNews.com) visually depict Obama more negatively than moderate sites (e...

Research typically reveals that outgroups are regarded with disinterest at best and hatred and enmity at worst. Working from an evolutionary framework, we identify a unique pattern of outgroup attraction. The small-group lifestyle of pre-human ancestors plausibly limited access to genetically diverse mates. Ancestral females may have solved the inb...

Understanding which characteristics of dynamic stimuli affect visual attention is crucial to usability research. We explored how object location and object luminosity differentially affect visual attention. Thirty-seven American participants viewed 34 Australian commercials, which were broken down by scene (N = 606) to identify all pertinent Areas...

Racial and ethnic biases often manifest without awareness. The underlying causes of these attitudes are not fully understood. While outgroup bias is well studied, ingroup bias has received far less attention. We examined ingroup biases among Hispanic women and outgroup biases toward Hispanics among White (Caucasian non-Hispanic) females using the s...

Musculoskeletal disorders (MSDs), including the back, neck, and upper and lower extremities, are debilitating conditions and, if not treated appropriately, can lead to poor occupational outcomes including reduced productivity, worker absenteeism, and long-term disability. Of these musculoskeletal regions, there is not as much research available on...

The mechanisms underlying the allocation of visual attention toward dynamic content are still largely unexplored. Due to the number of variables present during dynamic content, it is often difficult to confidently determine what components direct visual attention. In this study, we manipulated the presence of audio in an attempt to explore the cont...
