This Experiment Was Designed to Determine the Effect of Effort

Essay

This experiment was designed to determine the effect of effort during learning or persistence (resistance to extinction). A learning theorist required rats to climb inclined planes for food reward and then extinguished them on the same inclined planes. Three groups of rats were used-one group on a 10° plane, one on a 20° plane, and one on a 30° plane. The data below are responses during extinction. Analyze them completely. What conclusion should the learning theorist reach?
-Data Set 3a: $$\begin{array} { c c c } \text { Group 1 } \left( 10 ^ { \circ } \right) & \text { Group 2 } \left( 20 ^ { \circ } \right) & \text { Group } 3 \left( 30 ^ { \circ } \right) \\\hline 12 & 14 & 17 \\11 & 12 & 16 \\11 & 11 & 14 \\10 & 11 & 14 \\8 & 10 & 13 \\7 & 10 & 12 \\6 & 9 & 12 \\4 & 7 & 10 \\4 & 7 & 9 \\3 & 6 & 9\end{array}$$
