Previous studies reported cultural differences in neural activation for a variety
of cognitive functions including picture encoding, voting behavior, empathy, and
self-representation. Broad consensus exists that culture also asserts a significant
impact on the neural correlates of face processing, particularly regarding activation
of the amygdala, mostly reporting stronger or sustained activation to out-group
faces…
Mounting evidence indicates that humans have significant difficulties in
understanding emotional expressions from individuals of different ethnic
backgrounds, leading to reduced recognition accuracy and stronger amygdala
activation. However, the impact of gender on the behavioral and neural reactions
during the initial phase of cultural assimilation has not been addressed. Therefore,
we investigated 24 Asians students (12 females) and 24 age-matched European
students (12 females) during an explicit emotion recognition task, using Caucasian
facial expressions only, on a high-field MRI scanner.
Analysis of functional data revealed bilateral amygdala activation to emotional
expressions in Asian and European subjects. However, in the Asian sample, a
stronger response of the amygdala emerged and was paralleled by reduced
recognition accuracy, particularly for angry male faces. Moreover, no significant
gender difference emerged. We also observed a significant inverse correlation
between duration of stay and amygdala activation.
In concordance with previous results from our lab on male immigrants and our
hypothesis, bilateral amygdala activation in both samples was observed, confirming
the role of the amygdala as a ‘relevance detector’. The amygdala seems to be
fundamental in emotion processing as a part of the underlying neural network
although gender, socialization and cultural background seem to exert a certain
impact on its activation.
Taken together, this study demonstrates the first attempt to analyze the impact of
gender and culture on amygdala activation during emotion recognition. While we
observed no gender difference, culture and gender of poser asserted significant
effects on the behavioral and neural correlates of this emotional capacity, thereby
extending our knowledge on the bases of emotion recognition differences between
participants with divergent cultural backgrounds.

Culture lag can be most accurately defined as:
A) The delay in integrating novel technologies into the current cultural norms
B) The time it takes for foreigners or immigrants to adapt to the cultural norms
of the dominant society
C) The period between experiencing foreign cultural norms for the first time
and experiencing an interior disturbance as a result
D) The successful, though lengthy, process of spreading cultural norms
throughout a society
Correct answer is A
The definition in Answer A best fits the concept of “culture lag.” Culture lag refers
to the sociological phenomenon in which the various cultural norms of a society
tend to take a long time to adapt to novel technologies. In other words, there is a
significant “lag time” between when technologies may be introduced, available,
or even widely used and when the culture (and its norms, values, standards, and
expectations) has adequately adapted or shifted to incorporate those technologies.
