Seven Items, Happiness and Hard Questions: Psychology's Recent History

Introduction

As I finish my psychology degree, I have been reflecting on how the field has changed since its founding. The earlier modules traced schools that rose and faded over decades. This final paper examines three developments of the past seventy years that shape the field I am entering: the turn toward cognition, the rise of positive psychology and the replication crisis.

The Cognitive Turn

By the 1950s, behaviorism's exclusion of the mind faced growing challenges. Computers offered a new model of the mind as an information processor, linguists such as Noam Chomsky argued that language could not be explained by conditioning and researchers in memory, attention and perception began to study internal processes with experimental rigor.

The Magical Number Seven

Miller (1956) reviewed experiments on absolute judgment, in which people identify stimuli, such as tones or colors, along a single dimension, and on immediate memory span. He noted that across many kinds of stimuli, people's capacity to make accurate judgments and to remember items in sequence was limited to about seven items, plus or minus two. He distinguished the limit on information that could be transmitted in absolute judgment from the limit on the number of items that could be held in immediate memory and introduced the idea of chunking: people can increase what they remember by grouping items into larger meaningful units, such as remembering a phone number as three chunks rather than ten digits. His paper helped establish the information-processing approach and the study of memory limits as central topics of cognitive psychology.

The Growth of Cognitive Psychology

Through the 1960s and 1970s, cognitive psychology grew into a major field, studying attention, memory, language, problem solving and decision-making. Consistent with Leahey's argument from the first module, this change was gradual, building on the work of neobehaviorists such as Tolman, rather than a sudden revolution. Cognitive neuroscience later joined these questions with brain imaging.

Positive Psychology

Seligman and Csikszentmihalyi (2000) argued that since World War II, psychology had focused largely on pathology, healing damage within a disease model, and had neglected what makes life worth living. They called for a positive psychology studying three areas: positive subjective experiences, such as well-being, contentment, hope and flow; positive individual traits, such as courage, perseverance, wisdom and the capacity for love; and positive institutions that foster citizenship, responsibility and tolerance. They argued that understanding human strengths would help prevent mental illness as well as improve ordinary lives.

The Replication Crisis

In the 2010s, psychology faced a crisis of confidence. Hundreds of researchers joined forces to repeat 100 studies published in leading psychology journals (Open Science Collaboration, 2015). While nearly all the original studies had reported significant results, only about a third of the replications did, and the repeat studies found effects averaging roughly half the original size. Effects in cognitive psychology replicated somewhat more often than those in social psychology. The project prompted reforms, including preregistration of studies, larger samples and sharing of data and materials.

Continuity With the Past

These developments echo themes from earlier modules. The cognitive turn returned the mind to psychology, as Wundt and James had studied it, but with new methods. Positive psychology recalls the humanistic psychologists of the 1950s and 1960s, who also argued for studying growth and potential. The replication crisis recalls the problems of structuralism, whose introspective findings could not be verified across laboratories; once again, psychology is asking how to make its findings dependable.

Criticisms

Each development has critics. Some argue that cognitive psychology's computer metaphor neglects emotion and culture. Critics of positive psychology have questioned the strength of some interventions and its relative neglect of social conditions. Some researchers caution that failed replications can reflect differences in samples and methods as well as false original findings.

What Kind of Field I Am Entering

I am entering a field that studies the mind with sophisticated methods, increasingly attends to strengths as well as problems and is working openly to make its findings more reliable. Its history suggests that today's certainties will also be revised, which is less a weakness than a sign of a science that corrects itself.

Neuroscience and Psychology

Brain imaging techniques developed since the 1980s, such as functional MRI, allowed researchers to observe brain activity during mental tasks. Cognitive neuroscience now links questions about memory, attention and emotion to brain systems, continuing the physiological strand of psychology's history that began with Helmholtz.

Cultural Psychology

Researchers have also shown that many findings vary across cultures, challenging the assumption that research with Western participants describes all people. Cultural psychology studies how culture and mind shape each other.

Diversity in the Profession

The profession itself has changed. Women now earn most psychology doctorates in the United States, and efforts continue to increase representation of people from historically excluded groups, changing who asks psychology's questions.

Applied Psychology Today

Most psychologists now work in applied settings, such as health care, schools, organizations and the courts, rather than in laboratories, a change functionalists would have welcomed. Licensure, practice guidelines and evidence-based treatment standards now shape much of the profession.

Limits

This paper selects three developments among many, including cultural psychology, evolutionary psychology and the growth of applied fields, that also deserve attention.

Conclusion

Miller's work on the limits of information processing helped launch cognitive psychology, Seligman and Csikszentmihalyi called for a science of human strengths and the Open Science Collaboration exposed the fragility of many published findings and spurred reform. Psychology's recent history continues its longest tradition, debating what it should study and how it can know, and the course ends where the field always seems to be: learning from its past to correct its future.
