“…The unconscious mechanism of cost-benefit analysis is complex and constitutes the optimal strategy. The mechanism helps a person form a fight-or-flight decision when faced with a rival through holistic consideration of information including strength and limitations of the person and the rival, the probability of winning, chances of forming an alliance, and methods of distracting the rival to another rival (Dawkins, 1976;Trivers, 1985); however, the optimal solution cannot be reached through conscious consideration (Dijksterhuis, Bos, Nordgren, & van Baaren, 2006) because conscious, controlled, and effortful thinking works in sequential ways that accommodate only a limited amount of information, whereas unconscious, automatic, and effortless thinking works in parallel ways that allow abundant information to be considered simultaneously. The unconscious mechanism also helps determine somatic effort in pursuing reward, with more effort being paid to obtain higher reward, particularly when the task demand is high (Bijleveld, Custers, & Aarts, 2012).…”
