Which of the following statements about discrimination learning is FALSE?Group of answer choicesThe rate of discrimination learning is partly determined by both the difficulty of the discrimination and the intensity of the consequences when a correct or incorrect choice is made.Successful discrimination learning necessarily requires that the presence of the outcome corresponds with the presence a cue such that the two have a positive contingency.It can take longer to learn to discriminate between highly similar stimuli and, when we do, it can lead to biases in the way we generalise to other stimuli.Discrimination learning tends to reduce generalization to novel stimuli relative to a situation in which the learner only learns about a single stimulus.Passive exposure to the discriminative stimuli improves the learner’s ability to discriminate between them when they are associated with different consequences.
