When researchers added a few drops of vinegar to a brand-name beer, the beer tasters disliked it only if they had been told they were drinking vinegar-laced beer. this best illustrates the impact ofa. kinesthesis. b. feature detectors. c. perceptual set. d. interposition. e. the mcgurk effect.

Perceptual set

Explanation:

The perceptual process to the objects higher in our field of vision as the closer. it involves selection, inferences, and interpretation. It is more important in the active process. It is a process in which notice some aspects of perceptual data and ignore others. the factors that affect our perceptual tendencies are motivation, emotions, expectation, and culture. Sometimes it is helpful .It is a good example of top-down processing. Schema, mental framework, and concepts often guide the perceptual guide. Now we can say that perception is not responsible for what we see but the perceptual set has a vital role play in it. a variety of factor influences our perception.

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !

one way archaeology us understand the past is through the material objects it finds, allowing us to know what was being used, and when. for example a dig recently found a flute, believed to be the oldest musical instrument found to date.

i hope this
