Effects of Arousal

This entry is part 7 of 17 in the series Best Practices in Brain Training

Research indicates that extremely low and extremely high levels of arousal result in poor learning gain. Extremely low arousal results in errors of omission – being forgetful and unable to focus and concentrate on important things. Over-aroused individuals tend to lose proper restraint and act impulsively (Howard, 2006). Instruction should be engineered to generate the optimal level of arousal (Green & Bavelier, 2008). Apparently, the optimal level of arousal is task dependent. A high level of arousal works best for simple tasks, while a low level of arousal is more appropriate when performing complex tasks (Howard, 2006).
