Question

5)

A)Interstimulus interval -Define/explain what it is, and what it optimally should be.

b)Explain how the sequence of the CS and UCS matters - if the bell or the meat comes first in classical conditioning. What does the importance of the CS-UCS sequence show?

c)An individual’s learning history – explain how that matters in classical conditioning

d) Biological preparedness (BP) to learn certain associations, i.e., those that are threatening. Define/ explain what BP is.

Answer 1

The interstimulus interval (ISI) is the duration of time between the termination of one stimulus to the onset of another. When it comes to classical conditioning, the ISI is used to represent the gap of time between the start of the conditioned stimulus (CS) and the start of the unconditioned stimulus (US). The duration of the ISI should be sufficient for the organism to establish a link between the CS and US. There are usually two types of procedures involved. The first is delay conditioning, which is when the CS starts and continues until the US is released after a delay, then they both suspend at the same time. The other is trace conditioning, where the CS is shorter and stops before the US begins, leaving a gap between the two stimuli.
