Englargements and Modifications of Psychology
But is psychology simply the study of human consciousness? Not since Sigmund Freud. Based on case studies of patients, Freud insisted that unconscious processes were central to understanding human personality and its motivations. (The study of personality remains an important contemporary subfield.)
Animal behavior became part of psychology in 1897. Then Edward L. Thorndike, interested in the evolution of mind, brought various animals into his laboratory and studied their learning processes. Thus began comparative psychology, the subfield that compares the behavior of different species. And children became part of psychology’s concern when G. Stanley Hall and others took on the study of the development of mind from infancy through maturity, the subarea of developmental psychology.
Originally psychology was concerned with universal qualities of experience. Quantitative study of human differences began soon after mathematicians invented statistics. Francis Galton in 1884 and Alfred Binet in 1905 used statistics in constructing tests to measure intelligence. Statistics are now used in many subfields, and assessment of human differences remains a lively subarea.
In 1913, John Watson called for a new definition of psychology’s subject matter and method. The only way to make psychology into a true science was to base it on systematic behavioral observations. Psychology should abandon the study of mental life completely and become the science of behavior. Research psychologists heeded his call to base the field on systematic. Repeatable, behavioral observations—a position many, but not all, hold today. Though some continued to study mental processes, often through inferences from behavior (Wolfgang Kohler, Jean Piaget), mainstream experimental psychology embraced the definition: Psychology is the science of behavior.
The scope of psychology has expanded and evolved significantly since its inception, moving beyond the confines of the study of human consciousness. Sigmund Freud, a pioneering figure, catalyzed this shift by introducing the concept of unconscious processes. Drawing from case studies of patients, Freud emphasized the pivotal role of unconscious elements in understanding human personality and motivations. This emphasis on personality and its underlying dynamics has persisted, giving rise to contemporary subfields focused on the intricate realm of human personality.
The boundaries of psychology expanded further with the inclusion of animal behavior in 1897. Edward L. Thorndike’s interest in the evolution of the mind prompted him to investigate various animal species’ learning processes within his laboratory. This marked the inception of comparative psychology—a subfield devoted to comparing behavioral patterns across different species. Simultaneously, the study of child development entered psychology’s purview. G. Stanley Hall and other researchers undertook the exploration of cognitive maturation from infancy through adulthood, shaping the field of developmental psychology.
In its early days, psychology primarily concerned itself with universal aspects of human experience. The advent of statistics, following the development of mathematics, paved the way for the quantitative analysis of human differences. Notably, Francis Galton in 1884 and Alfred Binet in 1905 harnessed statistical tools to create intelligence tests. Today, statistics permeate various subfields, and the study of human variations remains a vibrant subarea within psychology.
In 1913, John Watson presented a transformative perspective on psychology’s subject matter and methodology. He advocated for a radical redefinition, asserting that psychology could only be a genuine science if grounded in systematic behavioral observations. Watson proposed that psychology should abandon the study of mental processes entirely and adopt a new identity—the science of behavior. This plea for systematic and repeatable behavioral observations resonated within the research community, and many embraced this position, which remains influential today. While some researchers continued to explore mental processes through behavioral inferences (as exemplified by Wolfgang Kohler and Jean Piaget), mainstream experimental psychology embraced the defining concept that psychology is the science of behavior.
The evolution of psychology, spanning its embrace of unconscious processes, animal behavior, child development, statistical analysis, and the science of behavior, exemplifies the field’s adaptability and responsiveness to the complexities of human experience. As psychology continues to develop, it remains an ever-evolving study that transcends narrow definitions, encompassing a broad spectrum of human behavior, cognition, and emotion.
During the mid-20th century, a convergence of various trends sparked a renewed interest in mental processes within the realm of experimental psychology. This resurgence of focus on cognitive aspects marked a significant shift in the field’s trajectory, driven by emerging technologies, linguistic advancements, and evolving perspectives on human development.
The advent of computers, hailed as information-processing machines, served as a catalyst for researchers to delve into the intricacies of how individuals perceive and think. Inspired by the potential parallels between human cognitive processes and computer information processing, psychologists embarked on investigations into the mechanisms of human information processing. This exploration gave rise to cognitive psychology, a subfield that delves into the internal processes underlying human cognition, including perception, memory, problem-solving, and decision-making.
Simultaneously, developments in linguistics ignited an interest in the mental underpinnings of language use. Psycholinguistics emerged as a major subarea within psychology, investigating the cognitive processes involved in language acquisition, comprehension, production, and communication. This intersection of psychology and linguistics expanded the scope of the field, encompassing the complex interactions between language and cognition.
The works of Jean Piaget, which had been penned earlier, gained recognition as seminal contributions to the understanding of cognitive development. His theories about the progression of cognitive abilities in children provided a framework for comprehending how mental processes evolve as individuals grow and mature.
George Miller’s influential textbook in 1962 marked a significant shift in emphasis, heralding the return of mental processes to the forefront of experimental psychology. The title of Miller’s textbook, “Psychology: The Science of Mental Life,” encapsulated this renewed focus on the intricacies of human cognition and consciousness.
Even as psychology expanded its embrace of mental processes, it remained a diverse and multifaceted field. Factors beyond the realm of psychology itself contributed to the broadening of its subject matter. The events surrounding World War II propelled the growth of social psychology, which intersects with sociology. The aftermath of the war prompted the influx of new researchers into the field, leading to the exploration of how social contexts and interactions shape psychological processes. Topics within social psychology included interpersonal relationships, social influence, attitudes and their change, prejudice, and strategies for resolving conflicts—a focus that persists in contemporary research.
This era marked a pivotal juncture for psychology, characterized by the reintegration of mental processes into the field’s core and the expansion of its boundaries into new domains. The resurgence of cognitive psychology, the birth of psycholinguistics, and the consolidation of cognitive development studies collectively reshaped psychology’s landscape, reflecting the dynamic interplay between scientific progress and evolving societal needs.
