Psych. Behaviorism Cognitive Psychology Revolution Definitions Distinction From Other Psychological Areas - A scientific disciplin can usually be diviede into 1. Basic areas - e.g., biological pyschology, social psychology 2. Applied areas - e.g., clinical psychology, educational psychology 3. Methodological areas - e.g., experimental psychology, quantitative psychology - Cognitive psychology is a basic area Introduction to Cognitive Psychology Department of Psychology 11 / 53 Cognitive Psychology Early Studies In Cog. Psych. Behaviorism Cognitive Psychology Revolution Definitions Distinction From Other Psychological Areas - Cognitive Psychology overlaps with several other disciplines concerning cognition - Cognitive Neuropsychology - study of the structure and function of the brain as it relates to cognition - Cognitive Neuroscience - study of the neural mechanisms of cognition - Cognitive Sciences - Interdisciplinary approach to understanding the mind - Combines aspects of cognitive psychology, philosophy of mind, neuroscience, psycholinguistics, computer science, etc. - Computational Cognitive Science - Developing computational models to understand human cognition Introduction to Cognitive Psychology Department of Psychology 12 / 53 Cognitive Psychology Early Studies In Cog. Psych. Behaviorism Cognitive Psychology Revolution Definitions Earliest Roots of Psychology Two approaches to understanding the human mind: 1. Philosophy - Seeks to understand the general nature of many aspects of the world, in part through introspection, the examination of inner ideas and experiences. - Rationalism vs. Empiricist 2. Physiology - Seeks a scientific study of life-sustaining functions in living matter, primarily through empirical methods. Introduction to Cognitive Psychology Department of Psychology 13 / 53 Cognitive Psychology Early Studies In Cog. Psych. Behaviorism Cognitive Psychology Revolution Philosophical Origins of Psychology Rationalism vs. Empiricism 1. Rationalist (e.g Plato) - The route to acquire knowledge is through thinking and logical analysis. - A rationalist who is interested in cognitive processes would appeal to reason as a source of knowledge or justification. - Rationalism is important in theory 2. Empiricist (e.g Aristotle). - The route to acquire knowledge is via empirical evidence. - To explore how the human mind works, empiricists would design experiments and conduct studies in which they could observe the behavior and processes of interest to them. - Empiricism leads directly to empirical investigations of psychology. Introduction to Cognitive Psychology Department of Psychology 14 / 53 Cognitive Psychology Early Studies In Cog. Psych. Behaviorism Cognitive Psychology Revolution Philosophical Origins of Psychology Synthesis - The contrasting ideas of rationalism and empiricism became prominent with: - French rationalist René Descartes (1596–1650): Introspective (reflective method) as superior than empirical methods. - British empiricist John Locke (1632–1704): Empirical observation. Study of learning was the key to understanding the human mind. - Immanuel Kant (1724–1804) synthesized the views of Descartes and Locke. - In 1800s ideas about the mind were dominated by the belief that it is not possible to study the mind (rationalism) - Mind cannot being study itself - Mind properties can not be measured Introduction to Cognitive Psychology Department of Psychology 15 / 53 Cognitive Psychology Early Studies In Cog.

Introduction to Cognitive Psychology Department of Psychology 17 / 53 Cognitive Psychology Early Studies In Cog. Psych. Behaviorism Cognitive Psychology Revolution Structuralism and Analytic Introspection Overview - Dominated psychology until early 1900s - Seeks to understand the structure of the mind and its perceptions by analyzing those perceptions into their constituent components (affection, attention, memory, and sensation). - Interested in how those elementary components work together to create the mind. - Introduce the analytic introspection - Moving from rationalism to empiricism (observe behaviors to draw conclusions) - Technique in which trained participants described their experiences and thought processes in response to stimuli. Introduction to Cognitive Psychology Department of Psychology 18 / 53 Cognitive Psychology Early Studies In Cog. Psych. Behaviorism Cognitive Psychology Revolution Structuralism and Analytic Introspection Wilhelm Wundt (1832-1920): Structuralism and Sensations - First laboratory of scientific psychology (1789) - Research purpose - Description of the basic elements of experience - Research method: Analytic Introspection - Described thought processes in response to stimuli. - Contribution - Studying behavior and the mind under controlled conditions. Figure 1: Wilhelm - Challenges/disadvantages of Introspection Wundt Probably - People may struggle to express thoughts clearly Thinking About or accurately. Structuralism - Verbalizing thoughts can change thinking process. Introduction to Cognitive Psychology Department of Psychology 19 / 53 Cognitive Psychology Early Studies In Cog. Psych. Behaviorism Cognitive Psychology Revolution Functionalism and Associationism Overview - Functionalism - Seeks to understand what people do and why they do it - Focus on study the processes of thought rather than to study the structural contents and elements of the mind. - Emphasizes the importance of empirical and rational thought over trial-and-error experimentation. - Particularly interested in the practical applications of their research - Pragmatism. - Knowledge is validated by its usefulness - What people do and how we can use that knowledge - Associationism - Examines how elements of the mind, such as events or ideas, can become associated with one another in the mind to result in a form of learning Introduction to Cognitive Psychology Department of Psychology 20 / 53 Cognitive Psychology Early Studies In Cog.

Behaviorism Cognitive Psychology Revolution Functionalism and Associationism Class Activity: Reflection Activity How might you apply Ebbinghaus’ forgetting curve to develop a more effective study schedule for retaining information over time? Consider factors like the timing and frequency of review sessions. A more effective study schedule based on Ebbinghaus’ forgetting curve would involve spaced repetition. This means reviewing the material at gradually increasing intervals after the initial learning session. For example: - First Review: Review the material shortly after the initial learning, to reinforce the information before significant forgetting occurs. - Second Review: Review again a few days later to strengthen the memory and slow down the forgetting process. - Subsequent Reviews: Continue reviewing the material at longer intervals (e.g., one week, two weeks, and then a month) to maintain retention over time.
