Science Summary Prompt

An error that adults seem to not outgrow is to “overestimate how much information they can garner through vision” (Wang JJ). An experiment was done recently, by Jessica Wang and some of her colleagues, to test how much information people believe they receive through vision. They constructed a box that “a person could only identify the colour of the object inside by lifting up a cover; could only determine its temperature by putting their finger in a hole in the side; and could only judge the object's weight by lifting an attached string” (Wang JJ). Then, they showed 24 students images of a either lifting the cover, sticking their finger in the hole, or lifting the string. Each student was asked questions after viewing the images about one of the 3 actions, such as “does the man know if he box is cold?” after lifting the cover, which the correct answer would be no. They were most interested in how long it took each student to respond, and the change between the times for each action. The students would tend to hesitate when asked if they could see the temperature of the box or see the weight of the box (Wang JJ). The text book talks about "misperceptions of sensory inputs", a false perception of a real stimulus, which might apply to situations like thinking you can see a temperature (Wood, Samuel E.).
