Subjects completed a baseline stimulus matching procedure designed to produce two symmetrical stimulus relations; A1-B1 and A2-B2. Using A1, B1, and two novel stimuli, subjects were then trained to produce a common key-press response for two stimuli and a second key-press response for two further stimuli across two blocks of response training.…

The current study assessed the sexual categorization of children among a random sample of adults from the general population. Twenty-seven males and 27 females (N = 54) were exposed to a categorization task that assessed their ability to discriminate adult- from child-related words and sexual from non-sexual words. Then, in a modified Implicit…

The Implicit Relational Assessment Procedure (IRAP) is a relatively new measure of implicit cognition that tests cognition as relational behavior instead of an associative activity and thus may provide a more specific measure of cognitive repertoires, including those for social biases, than better known implicit measures such as the Implicit…

The current study aimed to assess the implicit attitudes of vegetarians and non-vegetarians towards meat and vegetables, using the Implicit Association Test (IAT) and the Implicit Relational Assessment Procedure (IRAP). Both measures involved asking participants to respond, under time pressure, to pictures of meat or vegetables as either positive…

The Implicit Association Test (IAT) examines the differential association of 2 target concepts with 2 attribute concepts. Responding is predicted to be faster on consistent trials, when concepts that are associated in memory share a response key, than on inconsistent trials, when less associated items share a key. In the current study,…

Subjects were exposed to a word-picture association training phase in which each of 2 arbitrary nonsense syllables printed in blue and red font, respectively, were paired with either sexual or aversive photographic images. Subjects were then exposed to an equivalence training procedure that led to the formation of 2 3-member equivalence relations,…

The study examined the Implicit Relational Assessment Procedure's (IRAP) validity as a computerized response-latency-based measure of implicit self-esteem. University undergraduates and 2 sets of convicted prisoners participated. One set of prisoners resided in the main block, and the other in a privileged lower security "open area" of a…

The current study aimed to test the validity of the Implicit Relational Assessment Procedure (IRAP), as compared to the Implicit Association Test (IAT), by assessing the attitudes of Dublin dwellers and rural dwellers toward Dublin and country life. Discrimination between the two groups for the IAT was marginally significant. The IRAP…
