Methodology: How Social Psychologists Do Research 43
These methodological advances have been spurred on by new questions about the origins of social behavior, because new questions and new methods often develop hand in hand. New Frontiers in Social Psychological Research.
Culture and Social Psychology Social psychology largely began as a Western science, conducted by Western social psychologists with Western participants. This raises the question of how universal the findings are. To study the effects of culture on social psychological process, social psychologists conduct cross-cultural research (Cohen, 2014; Gelfand, Chiu, & Hong, 2014; Heine, 2010; Kitayama & Cohen, 2007; Miller & Boyle, 2013; Nisbett, 2003). Some findings in social psychology are culture-dependent, as we will see throughout this book. In Chapter 3, for example, we will see that Westerners and East Asians rely on fundamentally different kinds of thought to perceive and understand the social world. In Chapter 5, we’ll discuss cultural differences in the very way people define themselves. Whether we emphasize personal independence or social interdependence reflects our cultural values (Henrich, Heine, & Norenzayan, 2010).
Conducting cross-cultural research is not simply a matter of traveling to another culture, translating materials into the local language, and replicating a study there (Heine et al., 2002; van de Vijver & Leung, 1997). Researchers have to guard against imposing their own viewpoints and definitions, learned from their culture, onto another culture with which they are unfamiliar. They must also be sure that their inde- pendent and dependent variables are understood in the same way in different cultures (Bond, 1988; Lonner & Berry, 1986). New Frontiers in Social Psychological Research.
Suppose, for example, that you wanted to replicate the Latané and Darley (1968) seizure experiment in another culture. Clearly, you could not conduct the identical experiment somewhere else. The tape-recorded discussion of college life used by Latané and Darley was specific to the lives of New York University students in the 1960s and could not be used meaningfully elsewhere. What about more subtle aspects of the study, such as the way people viewed the person who had the seizure? Cultures vary considerably in how they define whether or not another person belongs to their social group; this factor figures significantly in how they behave toward that person (Gudykunst, 1988; Triandis, 1989).

If people in one culture view the victim as a member of their social group but people in another culture perceive the victim as a member of a rival social group, you might find very different results in the two cultures—not because the psychological processes of helping behavior are different, but because people interpreted the situation differently. It can be quite daunting to conduct a study that is interpreted and perceived similarly in dissimilar cultures. Cross- cultural researchers are sensitive to these issues, and as more and more cross-cultural research is conducted carefully, we will be able to determine which social psycholog- ical processes are universal and which are culture-bound (Heine, 2010).

For example, there is substantial evidence that playing violent video games makes people act in more aggressive ways and makes them less likely to help others. But is this true just in Western countries? A recent review of the literature compared studies of video games in the United States and Japan. As it happened, the deleterious effects of violent video games were the same in both countries (Anderson et al., 2010). New Frontiers in Social Psychological Research.
The Evolutionary Approach Evolutionary theory was developed by Charles Darwin (1859) to explain the ways in which animals adapt to their environments. Central to the theory is natural selection, the process by which heritable traits that promote survival in a particular environment are passed along to future generations, because organisms with those traits are more likely to produce offspring. A common example is how giraffes came to have long necks. In an environment where food is scarce, giraffes that happened to have …
Some basic psychological processes are universal, whereas others are shaped by the culture in which we live. For example, are people’s self-concepts shaped by cultural rules of how people must present themselves, such as the requirement by the Taliban regime in Afghanistan that women cover themselves from head to toe? Cross-cultural research is challenging but necessary for exploring how culture influences the basic ways in which people think about and interact with others.
Cross-Cultural Research Research conducted with members of different cultures, to see whether the psychological processes of interest are present in both cultures or whether they are specific to the culture in which people were raised. New Frontiers in Social Psychological Research.
Natural Selection The process by which heritable traits that promote survival in a particular environment are passed along to future generations; organisms with those traits are more likely to produce offspring long necks could feed on foliage that other animals couldn’t reach. These giraffes were more likely to survive and produce offspring than were other giraffes, the story goes, and the “long neck” gene thus became common in subsequent generations.
In biology, evolutionary theory is used to explain how different species acquired physical traits such as long necks. But what about social behaviors, such as the tendency to be aggressive toward a member of one’s own species or the tendency to be helpful to others? Is it possible that social behaviors have genetic determinants that evolve through the process of natural selection, and, if so, is this true in human beings as well as animals? These are the questions posed by evolutionary psychology, which attempts to explain social behavior in terms of genetic factors that have evolved over time according to the principles of natural selection. The core idea is that evolution occurs very slowly, such that social behaviors that are prevalent today, such as aggression and helping behavior, are due at least in part to adaptations to environments in our distant past (Buss, 2005; Durrant, Ellis, Nelson, Mizumori, & Weiner, 2013; Neuberg, Kenrick, & Schaller, 2010). New Frontiers in Social Psychological Research
We will discuss in upcoming chapters how evolutionary theory explains social behavior (e.g., Chapter 10 on interpersonal attraction, Chapter 11 on prosocial behavior, and Chapter 12 on aggression). Here, in our chapter on research methods, it is important to note that a lively debate has arisen over the testability of evolutionary hypotheses. Because current behaviors are thought to be adaptations to environmental conditions that existed thousands of years ago, psychologists make their best guesses about what those conditions were and how specific kinds of behaviors gave people a reproductive advantage. But these hypotheses are obviously impossible to test with the experimental method. And just because hypotheses sound plausible does not mean they are true.
For example, some scientists now believe that giraffes did not acquire a long neck in order to eat leaves in tall trees. Instead, they suggest, long necks first evolved in male giraffes to gain an advantage in fights with other males over access to females (Simmons & Scheepers, 1996). Which of these explanations is true? It’s hard to tell. On the other hand, evolutionary approaches can generate novel hypotheses about social behavior that can be tested with the other methods described in this chapter.

Social Neuroscience As we have seen, social psychology is concerned with how people’s thoughts, feelings, and behaviors are influenced by the real or imagined presence of other people. Most research studies in social psychology, then, study just that—thoughts, feelings, and behaviors. Human beings are biological organisms, however, and social psychologists have become increasingly interested in the connection between biological processes
and social behavior. These interests include the study of hormones and behavior, the human immune system, and neurological processes in the human brain. To study the brain and its relation to behavior, psychologists use sophisticated technologies, including electroencephalography (EEG), in which electrodes are placed on the scalp to measure electrical activity in the brain, and functional magnetic resonance imaging (fMRI), in which people are placed in scanners that measure changes in blood flow in their brains. Social psychologists take these measurements while participants think about and process social information, allowing them to correlate different kinds of brain activity with social information processing. This kind of research promises to open up a whole new area of inquiry into the relationship of the brain to behavior (Cacioppo & Cacioppo, 2013; Chiao et al., 2010; Lieberman, 2013; Ochsner, 2007).
