Abstract

Spatial–Numerical Association Of Response Codes (SNARC) and Spatial–Quantity Association Of Response Codes (SQARC) effects are evident when people produce faster leftsided responses to smaller numbers, sizes and durations and faster right-sided responses to larger numbers, sizes and durations. SQARC effects have typically been demonstrated in paradigms where the explicit processing of quantity information is required for successful task completion. The current study tested whether the implicit presentation of task-irrelevant magnitude information could trigger a SQARC effect as has been demonstrated previously when task-irrelevant information triggers a SNARC effect (Mitchell, Bull & Cleland, 2012). In Experiment 1 participants (n = 20) made orientation judgments for triangles varying in numerosity and physical extent. In Experiment 2 participants (n = 20) made orientation judgments for triangles varying in numerosity and for a triangle preceded by a delay of varying duration. SNARC effects were observed for the numerosity conditions of Experiment 1 and 2 replicating Mitchell et al., (2012). SQARC effects were also demonstrated for physical extent and for duration. These findings demonstrate that SQARC effects can be implicitly triggered by the presentation of the task-irrelevant magnitude.
