question 24

Multiple Choice

When the correlation coefficient is weak, the researcher must consider two possibilities:

• A)there simply is no consistent, systematic relationship between the two items in the population and the association exists, but it is not linear and must be investigated further.
• B)there is a consistent, systematic relationship between the two items in the population, but it is not linear and must be investigated further.
• C)there simply is no consistent, systematic relationship between the two items in the population and the association exists, but it is linear and must be investigated further.
• D)there simply is no consistent, systematic relationship between the two items in the population and the association exists, but it is linear and does not need be investigated further.
• E)there is a consistent, systematic relationship between the two items in the population, but it is linear and must be investigated further.

Shaping

A method used in behavioral training where successive approximations of a desired behavior are reinforced.

Successive Approximations

A method in behavior therapy and training in which complex behaviors are broken down into simpler steps, and these steps are learned gradually to achieve the target behavior.

Negative Reinforcement

A form of reinforcement in which the removal or avoidance of an unpleasant stimulus increases the probability of a behavior being repeated.

Tertiary Reinforcement

A type of reinforcement that uses a stimulus associated with primary or secondary reinforcers to modify behavior.
