Why do the findings of this study have important implications for cognitive functioning in minority groups?
Racism's Cognitive Toll: Subtle Discrimination is More Taxing on the Brain
The findings of this articles have important implications for the cognitive functions of racial minorities because they imply that racial minorities will often have problems with cognition. In cases where a member of a racial minority is confronted with subtle discrimination (which may be frequent), he or she will (the article implies) have reduced cognitive function.
When a person has to deal with subtle discrimination, their brain is distracted as it tries to process that discrimination. While this is happening, they will not be as sharp in dealing with other tasks. If this goes on often, the person will have a chronic problem with their cognitive function. This will, presumably, affect their performance in school, at work, etc.
For this reason, the study has major implications for cognitive function in racial minorities.
