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.
