Self-report vs. Behavioral Measures of Recycling

One of the challenges in measuring an experimental variable is identifying the technique that will produce the more accurate measurement. The most common way to measure a dependent variable is self-report—asking the participant to describe his/her feelings, thoughts, or behaviors. Yet, people may not be honest. To truly know something about a participant, it may be necessary to see what they actually do in a situation. This video uses a multi-group experiment to see if feeling close to others results in more favorable attitudes toward environmental consciousness measured both by self-report and behavioral observation. Psychological studies often use higher sample sizes than studies in other sciences. A large number of participants helps to better ensure that the population under study is better represented, i.e., the margin of error accompanied by studying human behavior is sufficiently accounted for. In this video, we demonstrate this experiment using just one participant. However, as represented in the results, we used a total of 186 participants to reach the experiment’s conclusions.

Inducing Emotions

Psychologists have long known that people behave differently in good moods versus bad moods, and this general principle extends to consumer behavior. Economists, as well, have come to appreciate that an individual’s financial decisions are not solely the result of extensive cost-benefit calculations; other factors like emotion are at play. Further, incidental emotions affect the behavior of buyers and sellers even though they are unrelated to the transaction at hand. While earlier research focused on the impact of global feelings (positive-negative), more recent research examines more specific emotions (e.g., anger and fear). In consumer settings, research shows that anger triggers greater risk-seeking behavior among buyers and sellers and that fear triggers the opposite, i.e., conservative behavior.   The following experiment tests how two specific negative emotions—disgust and sadness—influence people’s financial valuation of objects.1 The experiment examines the relationships between induced emotional states (disgust and sadness) and the endowment effect. Inherent in this experiment is a common technique for inducing specific emotions in a laboratory setting. Onc

The Implicit Association Test

One of the core constructs in social psychology is the notion of an attitude toward an object or person. Traditionally, psychologists measured attitudes by simply asking people to self-report their beliefs, opinions, or feelings. This approach has limitations, however, when measuring socially sensitive attitudes, like racial prejudice, because people are often motivated to self-report unprejudiced, egalitarian beliefs (despite harboring negative associations). In order to bypass this social-desirability bias, psychologists have developed a number of tasks that attempt to measure implicit attitudes that are less amenable to deliberate control (and potential distortion). The Implicit Association Test, or IAT, is one of the most influential measures of these unconscious attitudes. The IAT was first introduced in a 1998 paper by Anthony Greenwald and colleagues.1 This video will demonstrate how to conduct the IAT used in the final experiment, where European American participants (who report explicit egalitarian attitudes) exhibit implicit preferences for their own race.

Marginal Dishonesty: The Adding-to-10 Task

JoVE 10307

Classical economic theory asserts that people are rational and self-interested. In addition to seeking wealth and status, people are motivated by other goals. As a result, financial motives can sometimes be dwarfed by other internal needs, such as maintaining a positive self-concept or affiliating with other group members. Ethical dilemmas, such as the temptation to cheat on taxes, can result when these motives are in conflict. On the one hand, people may be tempted to save money by underreporting their taxable income. On the other hand, no one wants to perceive themselves as a dishonest, free-rider. As a result, people are reluctant to fully exploit unethical opportunities because doing so can severely undermine their self-image as morally upstanding individuals. Instead, people cheat to a much smaller degree than they are capable of: just enough to gain additional resources, but not so much as to compromise their self-image. This tendency for marginal dishonesty, or the "fudge factor," is an important principle in social psychology and can be tested through a variety of techniques. Mazar, Amir, and Ariely originally described six separate experiments involving (dis)honesty and a theory of se
