A modified Stroop task with sexual offenders: Replication of a study

Abstract

Cognitive–behavioural treatment of sexual offenders assumes that sexual offenders are motivated by deviant attitudes, perceptions and values. Although aspects of deviant schema can be assessed by questionnaires, self-report measures are limited by the respondent's willingness to be forthright and by the fact that, typically, these cognitive processes occur quickly, revealing signs of automaticity. Recent research by Smith and Waterman has suggested that the deviant schema of sexual offenders could be assessed using a version of the Stroop colour-naming task. Long latency periods to sexual colour words imply a longer information-processing route and evidence of pre-established (deviant) sexual cognitive schema. Stroop techniques may offer the advantage of eliminating limitations that arise when using self-report techniques, such as fakeability and social desirability concerns. The current study replicates and extends Smith and Waterman's results using samples of sexual offenders, non-sexual violent offenders and non-violent offenders. The cumulative results of the two studies suggests that Stroop techniques have promise, but that further work is required before measures are available that have sufficient reliability and validity to be used in applied contexts.
