Which Reaction Time Data Set Demonstrates the Typicality Effect for the Bird Category?
Which of the following reaction time data sets illustrate the typicality effect for the bird category, given the following three trials? (NOTE: Read data sets as RTs for Trial 1: Trial 2: Trial 3) Trial 1: An owl is a bird. Trial 2: A penguin is a bird. Trial 3: A sparrow is a bird. A. 583: 518: 653 msec B. 518: 583: 653 msec C. 583: 653: 518 msec D. 653: 583: 518 msec
The data set that illustrates the typicality effect for the bird category is option C: 583: 653: 518 msec.
The typicality effect refers to the phenomenon where reaction times are faster for stimuli that are more typical or representative of a category. In this case, the stimuli are different bird examples. Looking at the data sets provided, we can see that in Trial 1, the reaction time is 583 msec, in Trial 2, the reaction time is 653 msec, and in Trial 3, the reaction time is 518 msec. The data set that demonstrates the typicality effect is where the reaction time for the more typical bird stimuli (Trial 1 and Trial 3) is faster compared to the less typical bird stimulus (Trial 2). Option C: 583: 653: 518 msec represents the faster reaction times for the more typical bird stimuli in Trials 1 and 3 (583 and 518 msec, respectively), while the reaction time for the less typical bird stimulus in Trial 2 is slower (653 msec). Therefore, option C illustrates the typicality effect for the bird category.
