Have Your Children Had Their Anti-Smoking Shots?

Findings

In the early 1960s, social psychologist William McGuire published some classic papers showing that it is surprisingly easy to change people’s attitudes about things that we all wholeheartedly accept as true. For example, for speakers armed with a little knowledge of persuasion, it is remarkably easy to convince almost anyone that brushing one’s teeth is not such a great idea. McGuire’s insight into this curious phenomenon was that it is easy to change people’s minds about things that they have always taken for granted precisely because most people have little if any practice resisting attacks on attitudes that no one ever questions.

Taking this logic a little further, McGuire asked if it might be possible to train people to resist attacks on their beliefs by giving them practice at resisting arguments that they could easily refute. Specifically, McGuire drew an analogy between biological resistance to disease and psychological resistance to persuasion. Biological inoculation works by exposing people to a weakened version of an attacking agent such as a virus. People’s bodies produce antibodies that make them immune to the attacking agent, and when a full-blown version of the agent hits later in life, people win the biological battle against the full-blown disease. Would giving people a little practice fending off a weak attack on their attitudes make it easier for people to resist stronger attacks on their attitudes that come along later? The answer turns out to be yes. McGuire coined the phrase attitude inoculation to refer to the process of resisting strong persuasive arguments by getting practice fighting off weaker versions of the same arguments.
Significance

Once attitude inoculation had been demonstrated consistently in the laboratory, researchers decided to see if attitude inoculation could be used to help parents, teachers, and social service agents deal with a pressing social problem that kills about 440,000 people in the U.S. every year: cigarette smoking. Smoking seemed like an ideal problem to study because children below the age of 10 or 12 almost always report negative attitudes about smoking. However, in the face of peer pressure to be cool, many of these same children become smokers during middle to late adolescence.
Practical Application

Adolescents change their attitudes about smoking (and become smokers) because of the power of peer pressure. Researchers quickly realized that if they could inoculate children against pro-smoking arguments (by teaching them to resist pressure from their peers who believed that smoking is “cool”), they might be able to reduce the chances that children would become smokers. A series of field studies of attitude inoculation, conducted in junior high schools and high schools throughout the country, demonstrated that brief interventions using attitude inoculation dramatically reduced rates of teenage smoking. For instance, in an early study by Cheryl Perry and colleagues (1980), high school students inoculated junior high schools students against smoking by having the younger kids role-play the kind of situations they might actually face with a peer who pressured them to try a cigarette. For example, when a role-playing peer called a student “chicken” for not being willing to try an imaginary cigarette, the student practiced answers such as “I’d be a real chicken if I smoked just to impress you.” The kids who were inoculated in this way were about half as likely to become smokers as were kids in a very similar school who did not receive this special intervention.

Public service advertising campaigns have also made use of attitude inoculation theory by encouraging parents to help their children devise strategies for saying no when peers encourage them to smoke. Programs that have made whole or partial use of attitude inoculation programs have repeatedly documented the effectiveness of attitude inoculation to prevent teenage smoking, to curb illicit drug use, and to reduce teenage pregnancies and sexually transmitted diseases. In comparison with old-fashioned interventions such as simple education about the risks of smoking or teenage pregnancy, attitude inoculation frequently reduces risky behaviors by 30-70% (see Botvin et al., 1995; Ellickson & Bell, 1990; Perry et al., 1980). As psychologist David Myers put it in his popular social psychology textbook, “Today any school district or teacher wishing to use the social psychological approach to smoking prevention can do so easily, inexpensively, and with the hope of significant reductions in future smoking rates and health costs.” So the next time you think about inoculating kids to keep them healthy, make sure you remember that one of the most important kinds of inoculation any kid can get is a psychological inoculation against tobacco.

Early Intervention Can Improve Low-Income Children’s Cognitive Skills and Academic Achievement

National Head Start program conceptualized while psychologists were beginning to study preventive intervention for young children living in poverty.
Findings
As a group, children who live in poverty tend to perform worse in school than do children from more privileged backgrounds. For the first half of the 20th century, researchers attributed this difference to inherent cognitive deficits. At the time, the prevailing belief was that the course of child development was dictated by biology and maturation. By the early 1960s, this position gave way to the notion popularized by psychologists such as J. McVicker Hunt and Benjamin Bloom that intelligence could rather easily be shaped by the environment. There was very little research at the time to support these speculations but a few psychologists had begun to study whether environmental manipulation could prevent poor cognitive outcomes. Results of studies by psychologists Susan Gray and Rupert Klaus (1965), Martin Deutsch (1965) and Bettye Caldwell and former U.S. Surgeon General Julius Richmond (1968) supported the notion that early attention to physical and psychological development could improve cognitive ability.
Significance

These preliminary results caught the attention of Sargent Shriver, President Lyndon Johnson’s chief strategist in implementing an arsenal of antipoverty programs as part of the War on Poverty. His idea for a school readiness program for children of the poor focused on breaking the cycle of poverty. Shriver reasoned that if poor children could begin school on an equal footing with wealthier classmates, they would have a better of chance of succeeding in school and avoiding poverty in adulthood. He appointed a planning committee of 13 professionals in physical and mental health, early education, social work, and developmental psychology. Their work helped shape what is now known as the federal Head Start program.

The three developmental psychologists in the group were Urie Bronfenbrenner, Mamie Clark, and Edward Zigler. Bronfenbrenner convinced the other members that intervention would be most effective if it involved not just the child but the family and community that comprise the child-rearing environment. Parent involvement in school operations and administration were unheard of at the time, but it became a cornerstone of Head Start and proved to be a major contributor to its success. Zigler had been trained as a scientist and was distressed that the new program was not going to be field-tested before its nationwide launch. Arguing that it was not wise to base such a massive, innovative program on good ideas and concepts but little empirical evidence, he insisted that research and evaluation be part of Head Start. When he later became the federal official responsible for administering the program, Zigler (often referred to as the “father of Head Start”) worked to cast Head Start as a national laboratory for the design of effective early childhood services.

Although it is difficult to summarize the hundreds of empirical studies of Head Start outcomes, Head Start does seem to produce a variety of benefits for most children who participate. Although some studies have suggested that the intellectual advantages gained from participation in Head Start gradually disappear as children progress through elementary school, some of these same studies have shown more lasting benefits in the areas of school achievement and adjustment.
Practical Application

Head Start began as a great experiment that over the years has yielded prolific results. Some 20 million children and families have participated in Head Start since the summer of 1965; current enrollment approaches one million annually, including those in the new Early Head Start that serves families with children from birth to age 3. Psychological research on early intervention has proliferated, creating an expansive literature and sound knowledge base. Many research ideas designed and tested in the Head Start laboratory have been adapted in a variety of service delivery programs. These include family support services, home visiting, a credentialing process for early childhood workers, and education for parenthood. Head Start’s efforts in preschool education spotlighted the value of school readiness and helped spur today’s movement toward universal preschool.
