The current investigation compares the results of two commonly used visual detection paradigmsthe standard adult button-press detection paradigm used in ohman, Flykt, and Esteves (2001), and the new child-friendly touch-screen detection paradigm used in LoBue and DeLoache (2008)within the same samples of adult participants. Results suggest that both paradigms produce the same pattern of findings with regard to detection latency for threat-relevant versus threat-irrelevant stimuli: Adults detected threat-relevant targets more quickly than threat-irrelevant targets across the varying procedures. However, results with respect to automaticity of detection as suggested by ohman et al. (2001) were only replicated with the classic button-press paradigm. The findings validate the touch-screen visual search procedure and have important implications for choosing an appropriate methodology for studying threat detection.
