Score: 0.?5 of 5 pie 4 4 cf 9 [6 complete] v } HW Score: 17.38%, 7.13 of 41 pts @112 a In an experiment, 15 babies were asked to watch a cl‘rnber attempt to ascend a hill. On Me occasionsI the baby witnesses the clin’ber fail to matte the climb. Then, the
baby witnesses either a helper toypush the climber up the hill, or a I’I‘nderer toy preventing the climber from maldng the ascent The toys were shown to each hwy in a
random lasl’l‘on. A second part of tt’I‘s experiment showed the climber approach the helper by, chh is not a surprising action, and then the climber approached the
tinderer toy, which is a surprising action. The amount of time the hwy watched the event was recorded. The mean difference in time spent watching the climber
approach the hinderer toy versus watching the climber approach the helper toy was 1.09 seconds with a standard deviation of 1.53 seconds lClemplete parts a through
