“…Thirteen out of the 16 studies identified reported that incentives such as small prizes (Birnbaum et al., 2002; de Marchi et al., 2020; Hendy et al., 2007; Machado, Ritchie et al., 2020, Marcano‐Olivier et al., 2021), raffle tickets (Machado, Ritchie et al., 2020), virtual currencies (Joyner et al., 2017), and stationery (Horne et al., 2009) increased children's liking, acceptance, willingness to try, and intake of vegetables. Incentives were commonly used together with modeling and education, with most of the interventions reporting positive effects (Birnbaum et al., 2002; Horne et al., 2009; Machado, Ritchie et al., 2020; McCormick et al., 2009; Presti et al., 2015; Song et al., 2016a; Wengreen et al., 2021, Marcano‐Olivier et al., 2021), except from one intervention targeting children with autism, in which no significant effect was reported (Taylor, Upton et al., 2013); however, results from the latter could be attributed to the small sample size ( n = 12) or the special needs of the children. Finally, in a study that used incentives in combination with repeated exposure to sweet peppers, an increase in the peppers’ consumption was only recorded in the exposure group and not in the group that was offered stickers if they would choose a piece of pepper (Wardle et al., 2003).…”
