— Not all behaviours are affected by cultural bias: Although there may be differences in rates of obedience (Milgram) and conformity (Asch) between collectivist and individualist cultures, universal behaviours still exist. For example research has found that facial expressions for anger, guilt and disgust were universally recognised across all cultures. In terms of attachment, interactional synchrony and reciprocity are universal features of infant-caregiver interactions. Therefore, this suggests that to fully understand behaviour, we must look at both universal and culture-bound examples.
