Impulse Control Studies

M&M Experiment with Chimps

• Sally Boysen conducted an experiment where chimps chose between two dishes of M&Ms but ended up with less due to their greedy impulses.

Comparison with Human Children

• Similar impulse control studies show that humans can resist temptation better than chimps. In one study from the 1970s, children who waited for more treats scored higher on SAT tests later in life.

Emotional Reactivity and Problem Solving

Evolutionary Insights

• The speaker suggests that humans evolved to be less emotionally reactive than apes, which may explain differences in problem-solving abilities.

Training Chimps for Better Decision Making

Numeral Understanding Experiment
