Abstract

Various cultures exhibit different efficiencies when searching for the same simple geometric figure. In Canada and the United States, it is more efficient to search for a long line among short lines than vice versa (typical search asymmetry: Treisman & Gormican, 1988), whereas in Japan and Taiwan, searching for a long line among short lines is equally efficient as searching for a short line among long lines (Tsai et al., 2021; Ueda et al., 2018). One explanation for this variation is the default deployment of attention; search asymmetry might be observed after changing attention deployment even for Japanese and Taiwanese participants. To investigate this hypothesis, we modulated participants’ attention deployment before a visual search using a Navon task, in which participants were presented with a large letter composed of smaller letters and responded to either the large (i.e., global attention priming) or small letter (i.e., local attention priming). The results showed that local attention priming did not change search performances, maintaining no search asymmetry for both Japanese and Taiwanese. However, global attention priming led to the opposite-direction search asymmetry (i.e., a short line among long lines was searched more efficiently compared to vice versa) only for Taiwanese. Post-hoc analysis revealed that the opposite-direction search asymmetry is specific to participants who showed longer reaction times. These novel findings suggest that Japanese and Taiwanese participants default to local attention deployment in visual search, while those with longer reaction times employed a different search strategy with global attention priming. The emergence of opposite-direction search asymmetry raises new questions about how scenes with multiple objects are perceived and how individuals determine their attentional deployment in such scenarios.
