“…In contrast, performance following positive outcomes (win trials) tend to lead to a rough approximation of MES behaviour, but deviations from MES can be observed when the value of win is increased, making it more likely that the organism exhibits win-stay behavior (Forder & Dyson, 2016; see also Srihaput, Sundvall & Dyson, in preparation). Part of the reason why sub-optimal, exploitable lose-shift behaviour reliably occurs may be due to the self-imposed reduction in processing time allocated to decision making on trials following negative outcome (Dixon & Schreiber, 2004;Dyson, Sundvall, Forder & Douglas, 2018;Forder & Dyson, 2016;Verbruggen, Chambers, Lawrence & McLaren, 2017). Such ideas are also consistent with observations of tilting behaviour following loss in poker (e.g., Laakasuo et al, 2015), chasing behaviour following loss in roulette (e.g., Mitzenmacher & Upfal, 2005), and post-reinforcement pauses where gamblers revel in or 'consume' the current reward such that the initiation of the next trial takes longer following positive outcome (Dixon, MacLaren, Jarick, Fugelsang & Harrigan, 2013; see also Zheng et al, 2017).…”
