“…Several studies conducted within the framework of classic learning theories (Hull, 1943;Spence, 1956; see also Thibaut & Kelley, 1959;Zajonc, 1965) support the notion that the execution of complex responses suffers from states of high arousal while the execution of simple responses benefits from states of high arousal (e.g., Katahn & Koplin, 1966;Katahn & Lyda, 1966;Spence, Taylor, & Ketchel, 1956). While implementation intention theory posits that the instigation of responses occurs automatically as a function of forming if-then plans, it remains an open question as to whether the successful execution of responses is dependent on other factors such as arousal.…”
