By measuring semantic or associative relations between related and unrelated stimulus pairs, the first word is presented as a prime and the second word as a target.
Thus, two configurations can be used to test results: (1) A Type 2 probe without mask consisting of an undefined novel sample stimulus and comparison stimuli (defined, undefined from the exclusion probe, and novel undefined stimuli), with the correct response being the novel undefined stimulus; (2) A Type 4 probe without mask consisting of an undefined sample stimulus from the exclusion probe and comparison stimuli (defined, undefined from the exclusion probe and novel undefined stimulus), with the correct response being the undefined stimulus from the exclusion probe.
Data from 8 participants were removed for the following reasons: five participants fell asleep during the stimulus presentation; 3 participants showed artifacts in their EEG data due to simultaneously recorded eye movements.
In order to validate the SOR task as a perceptual learning procedure, the explorative behaviour of non-pathological adult rats was recorded in two experimental situations that differed in terms of the degree of similarity of the novel and the familiar stimulus.
