Power Posing: Brief Nonverbal Displays Affect Neuroendocrine Levels and Risk Tolerance

Dana Carney, Amy Cuddy & Andy Yap
Psychological Science, forthcoming

Abstract:
Humans and other animals express power through open, expansive postures, and they express powerlessness through closed, contractive postures. But can these postures actually cause power? The results of this study confirmed our prediction that posing in high-power nonverbal displays (as opposed to low-power nonverbal displays) would cause neuroendocrine and behavioral changes for both male and female participants: High-power posers experienced elevations in testosterone, decreases in cortisol, and increased feelings of power and tolerance for risk; low-power posers exhibited the opposite pattern. In short, posing in displays of power caused advantaged and adaptive psychological, physiological, and behavioral changes, and these findings suggest that embodiment extends beyond mere thinking and feeling, to physiology and subsequent behavioral choices. That a person can, by assuming two simple 1-min poses, embody power and instantly become more powerful has real-world, actionable implications.

Why Leaning to the Left Makes You Lean to the Left: Effect of Spatial Orientation on Political Attitudes

Daniel Oppenheimer & Thomas Trail
Social Cognition, October 2010, Pages 651-661

Abstract:
A prominent metaphor in American politics associates left with liberals and right with conservatives. Three studies investigate the extent to which this metaphor not only shapes how people talk about politics, but how people think about politics. Participants who are oriented to their right report more conservative political attitudes, while those who are oriented toward their left report more liberal attitudes. This supports the notion that spatial metaphor is a key ingredient underlying abstract thinking even for important belief systems.

Mere physical distance and integrative agreements: When more space improves negotiation outcomes

Marlone Deshaun Henderson
Journal of Experimental Social Psychology, forthcoming

Abstract:
We examined the effects of negotiating non face-to-face with someone that is physically nearby versus faraway on integrative (mutually beneficial) agreements. Across Studies 1 and 2, we found that individuals who negotiated with another person that they believed was physically faraway (several thousand feet away) rather than nearby (a few feet away) attained more integrative agreements (higher joint outcome, more Pareto efficient agreements). In Study 3, we found that the effect of different magnitudes of physical distance between negotiators on integrative agreements depended on negotiators' construal level: Individuals who negotiated with another person who was purportedly farther away achieved more integrative agreements when their level of construal was not constrained, but had no effect when they adopted a high-level of construal. Implications for non face-to-face communication are discussed.

No pain, no change: Reductions in prior negative affect following physical pain

Konrad Bresin, Kathryn Gordon, Theodore Bender, Linda Gordon & Thomas Joiner
Motivation and Emotion, September 2010, Pages 280-287

Abstract:
In general, organisms are motivated to avoid stimuli that induce pain. However, some individuals intentionally inflict pain on themselves (e.g., nonsuicidal self-injury) and report doing so for the perceived emotional benefits following the experience of pain. Two controlled laboratory studies sought to expand upon the relatively limited literature on the effects of pain on emotion. In Study 1, participants provided momentary affect ratings immediately before and after experiencing physical pain. Results demonstrated that both positive affect and negative affect (NA) decreased following the experience of pain. In Study 2, we examined the effect that individual differences in emotional reactivity had on affective reactions to pain. Individuals high in emotional reactivity experienced larger decreases in NA following the experience of pain than individuals who were low in emotional reactivity. Our findings may potentially explain why some individuals intentionally seek out the experience of pain.

Sleeping in Safe Places: An Experimental Investigation of Human Sleeping Place Preferences from an Evolutionary Perspective

Matthias Spörrle & Jennifer Stich
Evolutionary Psychology, August 2010, Pages 405-419

Abstract:
Although humans spend a third of their life asleep, their choice of sleeping places has so far been little investigated both theoretically and empirically. We address this issue from the perspective of evolutionary psychology. Our basic assumption is that humans have an evolved preference for safe sleeping places, that is, those that promise protection against potential aggressors and nighttime predation. Several testable predictions were derived from this assumption concerning the preferred location of the bed in a sleeping room. Specifically, we predicted that people prefer sleeping places that allow them to view the entrances to the sleeping room (doors and windows) from a distance while remaining concealed from the entrances themselves. To test these hypotheses, 138 participants were asked to arrange a bed and other pieces of furniture on floor plans that were experimentally manipulated with respect to the direction in which the door opened and the presence of a window. In agreement with predictions, participants predominantly positioned the bed in a way that (a) allowed them to see the door, (b) was as distant as possible from the door, and (c) was on the side of the room toward which the door opened. In addition, the positioning of the bed was influenced as predicted by the presence of a window.

Chemosensory signals of competition increase the skin conductance response in humans

Dirk Adolph, Sabine Schlösser, Maren Hawighorst & Bettina Pause
Physiology & Behavior, forthcoming

Abstract:
In vertebrates, chemosensory signals of competition are communicated between conspecifics, eliciting behavioral and physiological adaptations in the perceiving animal. The current study investigates, whether chemosensory signals of competition are also communicated between humans, and whether they elicit physiological changes in the perceiver. It is further investigated whether personality traits alter this physiological responding. Axillary sweat was collected from six male donors during a competition (badminton match) and a sport control condition (running). The donors' testosterone rose stronger during the competition as compared to the sport control condition. The chemosensory stimuli were presented to 18 (9 male) participants through a constant-flow olfactometer, while the skin conductance response (SCR) was measured. Results reveal that the SCR was larger in response to chemosensory signals collected during the competition condition as compared to those collected during the sport control condition. Furthermore, regression analyses showed, that higher scores on trait social anxiety were related to larger SCRs towards the chemosensory signals of competition. The current result suggests that chemosensory signals of competition can be communicated between humans, and that they elicit orienting in the perceiving individual. These data are consistent with current research, suggesting that high socially anxious individuals process threatening social information preferentially. The current results add to the growing body of research into human chemosensory communication of social information, and extend previous research on the chemosensory communication of anxiety.

The Color of Safety: Ingroup Associated Colors Make Beer Safer

Chris Loersch & Bruce Bartholow
Journal of Experimental Social Psychology, forthcoming

Abstract:
Individuals display high levels of trust and express feelings of safety when interacting with social ingroup members. Here, we investigated whether cues related to ingroup membership would change perceptions of the safety of alcohol. Participants were exposed to images of beer in either a standard can or a can featuring the colors of their university (i.e., ‘fan cans'). We hypothesized that exposure to fan cans would change perceptions of the risks of beer drinking. Results showed that participants exposed to fan cans rated beer consumption as less dangerous (Experiment 1), were more likely to automatically activate safety-related mental content after unconscious perception of beer cues (Experiment 2), and viewed their ingroup's party practices as less dangerous (Experiment 3). These results provide evidence that ingroup-associated colors can serve as a safety cue for alcohol, which may in theory perpetuate alcohol-related risk-taking, already a cause for concern on college and university campuses.

Pavlovian Processes in Consumer Choice: The Physical Presence of a Good Increases Willingness-to-Pay

Benjamin Bushong, Lindsay King, Colin Camerer & Antonio Rangel
American Economic Review, September 2010, Pages 1556-1571

Abstract:
This paper describes a series of laboratory experiments studying whether the form in which items are displayed at the time of decision affects the dollar value that subjects place on them. Using a Becker-DeGroot auction under three different conditions - (i) text displays, (ii) image displays, and (iii) displays of the actual items - we find that subjects' willingness-to-pay is 40-61 percent larger in the real than in the image and text displays. Furthermore, follow-up experiments suggest the presence of the real item triggers preprogrammed consummatory Pavlovian processes that promote behaviors that lead to contact with appetitive items whenever they are available.

The Ecology of Automaticity: How Situational Contingencies Shape Action Semantics and Social Behavior

Joseph Cesario, Jason Plaks, Nao Hagiwara, Carlos David Navarrete & Tory Higgins
Psychological Science, September 2010, Pages 1311-1317

Abstract:
What is the role of ecology in automatic cognitive processes and social behavior? Our motivated-preparation account posits that priming a social category readies the individual for adaptive behavioral responses to that category-responses that take into account the physical environment. We present the first evidence showing that the cognitive responses (Study 1) and the behavioral responses (Studies 2a and 2b) automatically elicited by a social-category prime differ depending on a person's physical surroundings. Specifically, after priming with pictures of Black men (a threatening out-group), participants responded with either aggressive behavior (fight) or distancing behavior (flight), depending on what action was allowed by the situation. For example, when participants were seated in an enclosed booth (no distancing behavior possible) during priming, they showed increased accessibility of fight-related action semantics; however, when seated in an open field (distancing behavior possible), they showed increased accessibility of flight-related action semantics. These findings suggest that an understanding of automaticity must consider its situated nature.

Do Blurred Faces Magnify Priming Effects? The Interactive Effects of Perceptual Fluency and Priming on Impression Formation

Ursula Sansom-Daly & Joseph Forgas
Social Cognition, October 2010, Pages 630-640

Abstract:
How do subtle subliminal cues such as perceptual fluency (e.g., the visual clarity of a face) and priming influence the way we form impressions of people? In this experiment, participants (N = 114) received an affective priming manipulation, and then viewed sharp (perceptually fluent) or slightly blurred (disfluent) photographs of target individuals. Impressions were assessed on a trait checking task, a trait rating task, and open-ended descriptions, and processing latency was also measured. Results indicated that both positive primes and greater fluency increased the positivity of impressions. In an interesting pattern, priming effects were greater for perceptually disfluent (blurred) faces, consistent with disfluent images also triggering more elaborate, constructive, and longer processing. These results are discussed in terms of the important and so far little understood interactive role of priming and fluency cues in impression formation judgments in everyday life.

Mind Your Mannerisms: Behavioral Mimicry Elicits Stereotype Conformity

Pontus Leander, Tanya Chartrand & Wendy Wood
Journal of Experimental Social Psychology, forthcoming

Abstract:
Four studies demonstrate that the affiliative responding that is typically encouraged by mimicry can be manifested in conformity to shared gender and racial stereotypes. In Studies 1 and 2, mimicry by a confederate led participants to perform in accordance with stereotypes about their race and gender on a math task. Studies 3 and 4 tested the boundary conditions of mimicry's influence: In Study 3, mimicry elicited stereotype-consistent math performance only among participants who believed in stereotypes about their group that could drive others' expectancies. Study 4 established that the mimicry must occur in the context of affiliation for it to elicit stereotype-consistent behavior, highlighting the important moderating role of affiliation motivation in this phenomenon. In sum, these findings suggest that mimicked individuals are more conforming to the stereotyped expectancies they believe other hold for them, which suggests not only a potential negative consequence of mimicry but also a subtle manner through which stereotypes may be perpetuated.

Squeeze me, but don't tease me: Human and mechanical touch enhance visual attention and emotion discrimination

Annett Schirmer et al.
Social Neuroscience, forthcoming

Abstract:
Being touched by another person influences our readiness to empathize with and support that person. We asked whether this influence arises from somatosensory experience, the proximity to the person and/or an attribution of the somatosensory experience to the person. Moreover, we were interested in whether and how touch affects the processing of ensuing events. To this end, we presented neutral and negative pictures with or without gentle pressure to the participants' forearm. In Experiment 1, pressure was applied by a friend, applied by a tactile device and attributed to the friend, or applied by a tactile device and attributed to a computer. Across these conditions, touch enhanced event-related potential (ERP) correlates of picture processing. Pictures elicited a larger posterior N100 and a late positivity discriminated more strongly between pictures of neutral and negative content when participants were touched. Experiment 2 replicated these findings while controlling for the predictive quality of touch. Experiment 3 replaced tactile contact with a tone, which failed to enhance N100 amplitude and emotion discrimination reflected by the late positivity. This indicates that touch sensitizes ongoing cognitive and emotional processes and that this sensitization is mediated by bottom-up somatosensory processing. Moreover, touch seems to be a special sensory signal that influences recipients in the absence of conscious reflection and that promotes prosocial behavior.

Can Video Games Enhance Creativity? Effects of Emotion Generated by Dance Dance Revolution

Elizabeth Hutton & Shyam Sundar
Creativity Research Journal, July 2010, Pages 294-303

Abstract:
What role does emotion play in helping youth reach their creative potential? Does it alter how they process ideas, and how many ideas they can generate? By varying the levels of arousal associated with low, medium, and high levels of exertion in the video game Dance Dance Revolution, and inducing a positive or negative mood, this study offers evidence that emotion significantly affects creativity through the interaction of arousal and valence. Faced with the cognitive demand of creativity, lower arousal levels resulted in higher creativity scores when coupled with a negative mood. At high arousal levels, a positive mood resulted in greater creative potential than a negative mood. These results are discussed here in light of theories of emotion as a prime, as information, and as a moderator of attention.

The state of tranquility: Subjective perception is shaped by contextual modulation of auditory connectivity

M.D. Hunter et al.
NeuroImage, 1 November 2010, Pages 611-618

Abstract:
In this study, we investigated brain mechanisms for the generation of subjective experience from objective sensory inputs. Our experimental construct was subjective tranquility. Tranquility is a mental state more likely to occur in the presence of objective sensory inputs that arise from natural features in the environment. We used functional magnetic resonance imaging to examine the neural response to scenes that were visually distinct (beach images vs. freeway images) and experienced as tranquil (beach) or non-tranquil (freeway). Both sets of scenes had the same auditory component because waves breaking on a beach and vehicles moving on a freeway can produce similar auditory spectral and temporal characteristics, perceived as a constant roar. Compared with scenes experienced as non-tranquil, we found that subjectively tranquil scenes were associated with significantly greater effective connectivity between the auditory cortex and medial prefrontal cortex, a region implicated in the evaluation of mental states. Similarly enhanced connectivity was also observed between the auditory cortex and posterior cingulate gyrus, temporoparietal cortex and thalamus. These findings demonstrate that visual context can modulate connectivity of the auditory cortex with regions implicated in the generation of subjective states. Importantly, this effect arises under conditions of identical auditory input. Hence, the same sound may be associated with different percepts reflecting varying connectivity between the auditory cortex and other brain regions. This suggests that subjective experience is more closely linked to the connectivity state of the auditory cortex than to its basic sensory inputs.

Alignment to visual speech information

Rachel Miller, Kauyumari Sanchez & Lawrence Rosenblum
Attention, Perception, & Psychophysics, August 2010, Pages 1614-1625

Abstract:
Speech alignment is the tendency for interlocutors to unconsciously imitate one another's speaking style. Alignment also occurs when a talker is asked to shadow recorded words (e.g., Shockley, Sabadini, & Fowler, 2004). In two experiments, we examined whether alignment could be induced with visual (lipread) speech and with auditory speech. In Experiment 1, we asked subjects to lipread and shadow out loud a model silently uttering words. The results indicate that shadowed utterances sounded more similar to the model's utterances than did subjects' nonshadowed read utterances. This suggests that speech alignment can be based on visual speech. In Experiment 2, we tested whether raters could perceive alignment across modalities. Raters were asked to judge the relative similarity between a model's visual (silent video) utterance and subjects' audio utterances. The subjects' shadowed utterances were again judged as more similar to the model's than were read utterances, suggesting that raters are sensitive to cross-modal similarity between aligned words.
