Nonconscious Mimicry Occurs when Affiliation Goals are Present

JoVE 10335

People are social chameleons and regularly engage in nonconscious behavioral mimicry. This occurs when an individual unwittingly imitates the behaviors of another person, such as crossing one's legs moments after a person sitting adjacent does so, or adjusting one's body posture to match a conversation partner. Rapport between two people increases behavioral mimicry, just as mimicry also increases rapport. Psychologists have posited that this mimicry is attributed to a perception-behavior link;1 seeing a person engage in a behavior activates that behavioral representation, which then makes the perceiver more likely to engage in that behavior him- or herself. The following experiment expands on these previous findings by testing whether people, without intention or awareness, use mimicry to their advantage. Because goals activate behavioral strategies and plans of action that help people pursue those goals,2 Lakin and Chartrand hypothesized that individuals would mimic another person more when they have a goal to affiliate than when they do not.3

Object Substitution Masking

Visual masking is a term used by perceptual scientists to refer to a wide range of phenomena in which in an image is presented but not perceived by an observer because of the presentation of a second image. There are several different kinds of masking, many of them relatively intuitive and unsurprising. But one surprising and important type of masking is called Object Substitution Masking. It has been a focus of research in vision science since it was discovered, relatively recently, around 1997 by Enns and Di Lollo.1 This video will demonstrate standard procedures for how to conduct an object substitution experiment, how to analyze the results, and it will also explain the hypothesized causes for this unusual form of masking.

Compound Administration III

There are many commonly used routes for compound administration in laboratory mice and rats. However, certain protocols may require the use of less commonly used routes, including intradermal, intranasal, and intracranial injections. Specialized training is essential for these procedures to be performed successfully. Justification for these routes may need to be provided to gain Institutional Animal Care and Use Committee (IACUC) approval.
