special senses
sight (visual), hearing (auditory), taste (gustatory), smell (olfactory), touch (tactile)
general senses
temperature, pain, vibration, joint position, proprioception
vision

stroop test
measures an individual’s ability to focus on the color of a word, while ignoring (filtering out) the meaning of the word
engagement of automatic and control processes
four exercises of the stroop test
monochrome, rectangles, words, colors
monochrome exercise
read names of some basic colors written in black
rectangles exercise
name the color of each rectangle
words exercise
read names of common colors written in different colors
colors exercise
name color used to write a common color
what is measured (recorded) during a stroop test?
number of errors, peripheral skin temperature, and heart rate
