This project evaluates the utility of a lexical decision task (LDT) for criminological research. LDTs are reaction-time tests where people quickly read sentence stems then indicate whether a subsequent letter string forms a word. LDTs are an alternative to popular yet problematic Implicit Association Tests for measuring implicit cognitions. The current study assesses whether LDT data are useful for: (1) measuring implicit theoretical constructs; (2) indicating survey respondent attention or data quality problems.
