Abstract

In 1977, Navon argued that perception is biased towards the processing of global as opposed to local visual information (or the forest before the trees) and implicitly assumed this to be true across places and cultures. Previous work with normally developing participants has supported this assumption except in one extremely remote African population. Here, we explore local–global perceptual bias in normally developing African participants living much less remotely than the African population tested previously. These participants had access to modern artefacts and education but presented with a local bias on a similarity-matching Navon task, contrary to Navon’s assumptions. Nevertheless, the urban and more educated amongst these participants showed a weaker local bias than the rural and less educated participants, suggesting an effect of urbanicity and education in driving differences in perceptual bias. Our findings confirm the impact of experience on perceptual bias and suggest that differences in the impact of education and urbanicity on lifestyles around the world can result in profound differences in perceptual style. In addition, they suggest that local bias is more common than previously thought; a global bias might not be universal after all.

According to the African Bank of Development, Rwanda’s real GDP grew by an average of 8% annually during the period 2000 to 2013, which is among the highest average growth rates in Africa (see “Rwanda − 2014 - Country Profile - African Development Bank”; http://​www.​afdb.​org). According to the World Bank, Rwanda might become a middle income country by 2020 (http://​www.​worldbank.​org/​en/​country/​rwanda/​overview).

This reanalysis left the data largely unchanged because the 6 stimuli used in this study were purposefully selected to be representative of performance on the full version of the test.
