Trowbridge and Cason asked students to draw lines of a certain length for thousands of trials. Some students were given no feedback, some were told right or wrong after each trial (right-wrong feedback), and some were told exactly how far off they were after each trial (how-much feedback). Which group(s) performed the best?
a. right-wrong feedback group and how-much feedback group both showed the same improvement because both are given rewards and punishments but the no feedback group did not improve
b. all groups improved equally because all get equal amounts of practice
c. the how-much feedback group performed best d. the no feedback group did the best because the students could learn on their own
Question 2
Trowbridge and Cason asked students to draw lines of a certain length for thousands of trials. Some students were given no feedback, some were told right or wrong after each trial (right-wrong feedback), and some were told exactly how far off they were after each trial (how-much feedback). According to a behaviorist interpretation of Thorndike's law of effect, which group(s) should perform the best?
a. right-wrong feedback group and how-much feedback group should both show the same improvement because both are given rewards and punishments but the no feedback group should not improve
b. all groups should improve equally because all get equal amounts of practice
c. the how-much feedback group should perform best because it gets more detailed information
d. the theory does not make a prediction
(a) Longevity decreases with increased horn-length breeding value of harvested rams. (b) Mean-weight
