Researchers wanted to determine if ideas about race affect our visual perception. In an experiment, white college students were asked to look at a screen with images of objects that were either crime-relevant (e.g., a handgun) or crime-irrelevant (e.g., a book). For each object, the first image was so blurry it was unrecognizable. The image became progressively clearer across 40 different frames until the students were able to correctly identify it.
Before they began the task, they were shown a photo for 50 milliseconds. The photo was of a black face, a white face, or an abstract line drawing. These "flashes" were subliminal images, meaning that the students were not aware of having seen them. Researchers wanted to find out whether seeing a black or white face, even without being aware of it, influenced the students' ability to identify the objects.
-The effects found in this study suggest that
A) few whites harbor a cultural association of African Americans with crime.
B) unconscious racial bias may influence real-world interactions between whites and African Americans.
C) most white college students are racist but are good at denying it.
D) people are almost always aware of their own beliefs and behaviors.

Quizplus · Accepted Answer

The experiment aimed to determine whether implicit (unconscious) racial bias affects visual perception. The results showed that exposure to a subliminal image of a black face led to slower recognition of crime-irrelevant objects but faster recognition of crime-relevant objects, suggesting that participants had a higher level of vigilance or alertness to crime-related stimuli after seeing a black face. This finding supports the idea that unconscious racial bias may influence real-world interactions between whites and African Americans. The other answer choices are not supported by the information provided in the passage.
