Virtually compliant: Immersive video gaming increases conformity to false computer judgments.

Real-life encounters with face-to-face contact are on the decline in a world in which many routine tasks are delegated to virtual characters-a development that bears both opportunities and risks. Interacting with such virtual-reality beings is particularly common during role-playing videogames, in which we incarnate into the virtual reality of an avatar. Video gaming is known to lead to the training and development of real-life skills and behaviors; hence, in the present study we sought to explore whether role-playing video gaming primes individuals' identification with a computer enough to increase computer-related social conformity. Following immersive video gaming, individuals were indeed more likely to give up their own best judgment and to follow the vote of computers, especially when the stimulus context was ambiguous. Implications for human-computer interactions and for our understanding of the formation of identity and self-concept are discussed.

Virtually numbed: immersive video gaming alters real-life experience.

As actors in a highly mechanized environment, we are citizens of a world populated not only by fellow humans, but also by virtual characters (avatars). Does immersive video gaming, during which the player takes on the mantle of an avatar, prompt people to adopt the coldness and rigidity associated with robotic behavior and desensitize them to real-life experience? In one study, we correlated participants' reported video-gaming behavior with their emotional rigidity (as indicated by the number of paperclips that they removed from ice-cold water). In a second experiment, we manipulated immersive and nonimmersive gaming behavior and then likewise measured the extent of the participants' emotional rigidity. Both studies yielded reliable impacts, and thus suggest that immersion into a robotic viewpoint desensitizes people to real-life experiences in oneself and others.

Mobilizing unused resources: using the placebo concept to enhance cognitive performance.

People have significant psychological resources to improve their well-being and performance, but these resources often go unused and could be better harnessed. In the medical domain, it is well established that these resources can be mobilized under certain conditions, for example in the context of the placebo effect. Here we explored whether the placebo principle can be used to enhance cognitive performance. To do so, we employed a modified placebo induction--a bogus priming method that we told participants would unconsciously enhance their knowledge and that they should hence trust their skills in an upcoming knowledge test. Participant performance was indeed enhanced, compared to a group that did not think the priming process would improve their knowledge. The study documents the relevance of the placebo effect outside the medical and therapeutic setting.

Afterimages of savages: implicit associations between primitives, animals and children.

Historically, traditional people have often been likened to animals and children. A study employing implicit social cognition methods examined whether these associations endure in a more subtle, implicit form. Consistent with colonial era portrayals of indigenous and other traditional people as 'primitives' or 'savages', participants continued to associate them with animal- and child-related stimuli more readily than people from modern, industrialized societies. In addition, traditional people were ascribed fewer uniquely human attributes than their modern counterparts. These findings, replicated with verbal and pictorial representations of the traditional/modern distinction, were independent of any positive or negative evaluation of traditional people. They imply that colonial 'images of savages' persist in contemporary western society as a cultural residue.

Animals and androids: implicit associations between social categories and nonhumans.

People commonly ascribe lesser humanness to others than to themselves. Two senses of humanness appear to be involved: attributes that are unique to humans and those that constitute essential "human nature." Denying uniquely human and human-nature attributes to other people may implicitly liken them to animals and automata, respectively. In the present study, the go/no-go association task was used to assess implicit associations among social categories exemplifying the two senses of humanness, traits representing these senses, and the two types of nonhumans. Congruent associations (among artists, human-nature traits, and animals; among businesspeople, uniquely human traits, and automata) were consistently stronger than incongruent associations. Explicit ratings supported these differential associations. Social perception may involve two subtle ways of dehumanizing others.
