question 11

Multiple Choice

• A)estimated variance of _j when the error term is normally distributed.
• B)estimated variance of a given coefficient when the error term is not normally distributed.
• C)square root of the estimated variance of _j when the error term is normally distributed.
• D)square root of the estimated variance of _j when the error term is not normally distributed.

Definitions:

Stimulus Substitution

A concept in conditioning where a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response.

Fixed Interval

A reinforcement schedule that rewards the first response following the passage of a specified time interval.

Variable Interval

A schedule of reinforcement where a response is rewarded after an unpredictable amount of time has passed, leading to a steady rate of response.

Fixed Ratio

In operant conditioning, a schedule of reinforcement where a response is reinforced only after a specified number of responses.
