How has early memory research concerning the growth of cognitive perspectives in psychology changed over the course of the 20th century?

To understand how early memory research regarding cognitive perspectives in psychology has changed over the 20th century, we need to explore the historical context and the key developments that have shaped this field.

1. Behaviorism Era (early 1900s): At the beginning of the 20th century, the dominant psychological perspective was behaviorism, which focused primarily on observable behaviors. Memory research during this period focused on studying stimulus-response relationships and the role of reinforcement and punishment in shaping behavior. However, the internal processes of memory were largely ignored.

2. Cognitive Revolution (1950s-1960s): In the mid-20th century, there was a shift in psychology towards a cognitive perspective. This revolution was largely inspired by advancements in technology, such as computers, which served as a metaphor for understanding the human mind as an information-processing system. Memory research during this era emphasized the study of mental processes, including attention, memory encoding, storage, and retrieval.

3. Information Processing and Models of Memory (1970s): During this period, memory research focused on developing models to explain how information is processed and stored in memory. The most influential model was the Information Processing Model, which divided memory into sensory memory, short-term memory, and long-term memory. Researchers used methods like experiments, observations, and self-report measures to investigate memory processes and how they might be affected by factors like attention, organization, and rehearsal.

4. Introduction of Cognitive Neuroscience (1980s-present): The development of new technologies, such as brain imaging techniques (e.g., fMRI, EEG), allowed researchers to study memory processes in the brain more directly. Cognitive neuroscience emerged as a field that combined cognitive psychology with neuroscience, aiming to understand the neural basis of memory and cognition. This integration has provided insights into how different brain regions are involved in memory formation, storage, and retrieval.

5. Focus on Cognitive Development (1990s-present): In recent decades, memory research has increasingly focused on understanding cognitive development in children and how memory processes change with age. This research explores the development of working memory, episodic memory, and other memory systems, shedding light on cognitive abilities in different stages of life.

In summary, memory research in psychology has evolved significantly over the 20th century. It has shifted from an exclusive focus on observable behaviors to encompassing the study of internal mental processes. Advancements in technology and the interdisciplinary integration of cognitive psychology and neuroscience have deepened our understanding of memory's cognitive and neural underpinnings. Additionally, research has begun to delve into the developmental aspects of memory to gain insights into how memory processes change over time.
