Study Notes
Here is a summary of the text in detailed bullet points:
• Cognitive psychology initially focused on mental processes and representations, but it was incomplete without considering the brain.
• The brain is composed of different neurons and neural grooves with biological structures, and studying it can help identify the processes required to complete tasks.
• Changes in brain structure and activity can be correlated to mental processes, and brain activity can signal whether a process is working or not.
• However, there is a challenge in identifying which brain networks lead to specific mental experiences, such as emotions, and how the brain labels these emotions.
• The structure-process trade-off is another problem in studying the brain, where the structure of the brain affects the processing of information.
• Saul Sternberg's experiment on list recognition demonstrated that information is accessed from memory through serial search, where the verification time increases with the length of the list.
• Later, Townsend proposed a parallel search process, where multiple processes occur simultaneously, and the verification time still increases with the length of the list.
• The inclusion of the brain in cognitive psychology helps identify the reasons for mental activities and how they take place.
• The idiocracy theory is the requirement of understanding what necessary or adequate processes are required for certain mental processes to take place, given the structural constraints of the brain.
• There are four paradigms in the study of cognitive psychology: information processing approach, connectivism, ecological approach, and embodied cognition.
• The information processing approach views cognition as information passing through a system, with stages such as detection, attention, short-term memory, and long-term memory.
• The information processing approach involves systems such as sensory memory, short-term memory, and long-term memory, and processes such as recognition, rehearsal, recording, reorganization, manipulation, and categorization.
• The goals of the information processing approach include response and understanding, achieved through the system of processes.- Connectionism is a theory that suggests mental experiences are formed through connections between small units, which compute goals by being appropriately connected to large numbers of situational units.
-
In connectionism, individual neurons in the brain do not transmit large amounts of symbolic information, but instead compute or come up with goals by being connected to large numbers of situational units.
-
Connectionism explains mental experiences through the connections between specialized systems, such as categorization in terms of living/non-living, birds, animals, and so on.
-
The sentence "Robin is a bird" is explained by connectionism, where "Robin" is a name that falls under the category of birds, and "is" is a connector that defines the relation between Robin and the word "bird".
-
The connections between systems lead to the idea of mental processes, such as the conclusion that since Robin is a bird, it should have wings and be able to fly.
-
Connectionism is not about big processes or systems, but about the connections between small units, which combine to give us mental experiences.
-
The units that combine to give us mental experiences have certain weights, and the weight-wise combination determines what features should be present in a particular entity.
-
The connectionist approach differs from the information processing approach, which involves a set of systems and processes that lead to a goal.
-
The evolutionary approach to studying cognitive psychology suggests that the study of mental processes should also consider evolutionary features and inputs, such as specialized cognitive abilities like language and three-dimensional perception.
-
The evolutionary approach views the human mind as a biological system that has evolved over generations, and certain features of the human mind are inbuilt and evolutionary in nature.
-
The ecological approach suggests that mental experiences or cognition do not occur in isolation, but are shaped by the context and culture in which they occur.
-
The ecological approach emphasizes the importance of studying cognition in terms of the ecology or culture in which people live, as different cultures process information differently.
-
The individualistic culture of Western countries and the collectivist culture of Asian countries, for example, lead to different ways of processing information and thinking.
-
The ecological approach suggests that all cognitive activities are shaped by the culture and context in which they occur.
-
The introduction to cognitive psychology covers the history of cognitive psychology, its subject matter, and various paradigms, including the information processing approach, connectionism, the evolutionary approach, and the ecological approach.
-
The next lecture will focus on how to study cognition, including the processing of mental activities or mental representations.
