Eye movement research reveals how people allocate visual attention when reading, scanning the environment around them(Rayner, 2012). These cognitive processes come together when people view what sociolinguists refer to as, the linguisticlandscape, consisting of signage in the public space. Linguistic landscapes around the world are jointly determined by top-down socio-legal provisions, and bottom-up capacities and attitudes of individual people (Leimgruber, Vingron, & Titone,2019). In a preliminary study, we found that bilinguals differed in how they viewed naturally occurring linguistic landscapeimages (Vingron et al., 2018). We are currently analyzing data from a follow-up study that investigated whether individualdifferences in language experience among bilinguals modulate their eye movements to artificial linguistic landscape imagesthat systematically manipulate text language, position, and size, while controlling for linguistic content.

Prior work examining executive control during the Simon task has focused on global congruency alone and/or has primarilycontrasted bilinguals with monolinguals. This is problematic for two reasons: (1) prior trial experience on current trialperformance is unaccounted for (Grundy et al., 2017) and (2) bilinguals are not a homogeneous group. Here, we examinedthe interaction between prior and current trial congruency in the Simon Task for 65 bilingual young adults who variedcontinuously in bilingual experience. Generally, current trial congruency effects were larger when the prior trial wascongruent vs. incongruent. However, as non-L1 experience increased, this interaction diminished; the overall prior trialeffect was reduced independently of age of acquisition. Crucially, neither non-L1 experience nor age of acquisitioninfluenced current trial congruency alone. Although preliminary, these results suggest that both congruency effects andbilingual experience influence performance on a non-linguistic executive control task.
