Study Notes

Studying Cognition

Methods to study cognition include measuring brain activity, observing behavior, reflecting on subjective experiences, and creating simulations.
The nature vs. nurture debate examines whether cognitive abilities are innate or learned.

Mind and Brain

The mind-body problem explores the relationship between mental events and physical mechanisms in the body.
Dualism asserts the mind and body are distinct but interact; Monism posits only one substance exists, leading to views like physicalism and neutral monism.
Understanding cognition may require insights from brain function, although complete understanding is still elusive.

The Brain and Behavior

The complexity of the brain hinders straightforward studies; human and chimpanzee brains show significant similarities, but individual differences influence behavior.
Observing behavior can provide insights into brain function.

Historical Approaches to Cognitive Psychology

Key historical perspectives include Structuralism, Behaviorism, and the Cognitive Approach.

Structuralism

Founded by Wilhelm Wundt in 1876, aimed at directly studying the mind via introspection.
Introspection involves careful self-reflection on internal experiences to uncover principles of consciousness.
Limitations include subjective data, inability for replication, and the impact of unconscious processes like cortical blindness.

Behaviorism

Initiated by John Watson in 1913, focuses on observable behaviors rather than internal thought processes.
Emphasizes the stimulus-response model, where stimuli cause predictable responses.
Classical conditioning, demonstrated by Pavlov, associates involuntary responses with specific stimuli.
Operant conditioning, introduced by B.F. Skinner, modifies voluntary behavior through rewards or punishments.

Limitations of Behaviorism

Behaviorism cannot fully explain novel behaviors or latent learning, where understanding occurs without direct conditioning.

The Rise of Computers

Computers process functions and map inputs to outputs through algorithms.
Alan Turing developed the Universal Turing Machine, illustrating programmability.
The brain's binary-like operation (neurons firing or not) influences cognitive science, leading to the Cognitive Revolution.

The Cognitivist Perspective

Cognition viewed as a function with input (sensory data), processing (mental manipulation), and output (behavior).
Aims to determine algorithms the brain uses for processing information.

The Cognitive Approach

Focuses on measuring objective behaviors to test theories about mental processes.
Mental imagery involves visualizing absent stimuli and illustrates cognitive processing.

Experimental Measures

Behavioral experiments assess stimulus effects on outcomes.
Variables include independent (manipulated) and dependent (measured responses), and variability must be accounted for through rigorous testing and representative sampling.

Complementary Approaches to Cognitive Psychology

Cognitive neuroscience blends behavioral studies with brain activity measurement for a holistic understanding.
Behavioral neuroscience combines behavior with physiological measures and involves techniques like lesioning, electrode implantation, and optogenetics.
Computational neuroscience uses computer models to simulate brain functions and cognitive tasks, aiding in understanding brain operations.
