Cultural Diversity and Saccade Similarities: Culture Does Not Explain Saccade Latency Differences between Chinese and Caucasian Participants
A central claim of cultural neuroscience is that the culture to which an individual belongs plays a key role in shaping basic cognitive processes and behaviours, including eye movement behaviour. We previously reported a robust difference in saccade behaviour between Chinese and Caucasian participants; Chinese participants are much more likely to execute low latency express saccades, in circumstances in which these are normally discouraged. To assess the extent to which this is the product of culture we compared a group of 70 Chinese overseas students (whose primary cultural exposure was that of mainland China), a group of 45 participants whose parents were Chinese but who themselves were brought up in the UK (whose primary cultural exposure was western European) and a group of 70 Caucasian participants. Results from the Schwartz Value Survey confirmed that the UK-Chinese group were culturally similar to the Caucasian group. However, their patterns of saccade latency were identical to the mainland Chinese group, and different to the Caucasian group. We conclude that at least for the relatively simple reflexive saccade behaviour we have investigated, culture cannot explain the observed differences in behaviour
A change in strategy: static emotion recognition in Malaysian Chinese
Studies have shown that while East Asians focused on the center of the face to recognize identities, participants adapted their strategy by focusing more on the eyes to identify emotions, suggesting that the eyes may contain salient information pertaining to emotional state in Eastern cultures. However, Western Caucasians employ the same strategy by moving between the eyes and mouth to identify both identities and emotions. Malaysian Chinese have been shown to focus on the eyes and nose more than the mouth during face recognition task, which represents an intermediate between Eastern and Western looking strategies. The current study examined whether Malaysian Chinese continue to employ an intermediate strategy or shift towards an Eastern or Western pattern (by fixating more on the eyes or mouth respectively) during an emotion recognition task. Participants focused more on the eyes, followed by the nose then mouth. Directing attention towards the eye region resulted in better recognition of certain own- than other-race emotions. Although the fixation patterns appear similar for both tasks, further analyses showed that fixations on the eyes were reduced whereas fixations on the nose and mouth were increased during emotion recognition, indicating that participants adapt looking strategies based on their aims.14 page(s

The thin white line: adaptation suggests a common neural mechanism for judgments of Asian and Caucasian body size
Visual adaptation has been proposed as a mechanism linking viewing images of thin women’s bodies with body size and shape misperception (BSSM). Non-Caucasian populations appear less susceptible to BSSM, possibly because adaptation to thin Caucasian bodies in Western media may not fully transfer to own-race bodies. Experiment 1 used a cross-adaptation paradigm to examine the transfer of body size aftereffects across races. Large aftereffects were found in the predicted directions for all conditions. The strength of aftereffects was statistically equivalent when the race of test stimuli was congruent vs. incongruent with the race of adaptation stimuli, suggesting complete transfer of aftereffects across races. Experiment 2 used a contingent-adaptation paradigm, finding that simultaneous adaptation to wide Asian and narrow Caucasian women’s bodies (or vice versa) results in no significant aftereffects for either congruent or incongruent conditions and statistically equivalent results for each. Equal and opposite adaptation effects may therefore transfer completely across races, canceling each other out. This suggests that body size is encoded by a race-general neural mechanism. Unexpectedly, Asian observers showed reduced body size aftereffects compared to Caucasian observers, regardless of the race of stimulus bodies, perhaps helping to explain why Asian populations appear less susceptible to BSSM
