“…In particular, the degree of sensory detail and vividness of remembered and imagined helping events predicted willingness to help (Gaesser et al, 2015;Gaesser, DiBiase, & Kensinger, in press;Gaesser, Dodds, & Schacter, in press;Gaesser & Schacter, 2014). These findings are consistent with previous research related to imagination inflation (Garry & Polaschek, 2000;Hyman & Pentland, 1996;Husnu & Crisp, 2010;Mazzoni & Memon, 2003, see also D'Argembeau & Van der Linden, 2012 and related work showing that directly manipulating vividness can enhance the perceived probability of imagined events occurring in the future (Szpunar & Schacter, 2013). As the remembered or imagined helping episode is more vividly experienced, the helping event becomes more accessible (Anderson, 1983;Koehler, 1991;Tversky & Kahneman, 1973), providing 'evidentiary value' (Kappes & Morewedge, 2016) that one is willing to help in that situation.…”
