Sleep, Learning, and Conditioning (Lecture Notes)

Flashcards covering sleep functions, dream content, and core concepts in learning and conditioning (classical and operant) as noted in the lecture.

What are the main functions of sleep mentioned in the notes?

Preservation from injury, energy conservation, restoration of bodily functions, memory consolidation, and support for growth.

What is memory consolidation?

The process by which memories become stable and integrated, often during sleep.

What is dream content described as in the notes?

Images, sensations, and thoughts that occur during sleep.

What is learning?

The process of acquiring through experience new information or behaviors.

What is associative learning?

Learning that two events occur together.

What is classical conditioning?

A learning process where two or more stimuli become linked and a response is elicited; typically a neutral stimulus becomes associated with an unconditioned stimulus to produce a conditioned response.

Who studied the digestive system in relation to conditioning?

Pavlov.

What is a Neutral Stimulus (NS)?

A stimulus that elicits no response before conditioning.

What is an Unconditioned Stimulus (US)?

A stimulus that naturally and automatically triggers a response.

What is a Conditioned Stimulus (CS)?

A previously neutral stimulus that, after association with the US, triggers a conditioned response.

What is an Unconditioned Response (UR)?

An unlearned, natural response to the unconditioned stimulus.

What is a Conditioned Response (CR)?

A learned response to the conditioned stimulus.

What is operant conditioning?

A learning process in which behaviors are strengthened or weakened by consequences (rewards or punishments).

What is the key difference between classical conditioning and operant conditioning?

Classical conditioning links stimuli to a response; operant conditioning links a behavior to its consequences.
