“…In other words, the implementation of the program significantly increased the perspective-taking performances of the treatment group when compared to the nonintervention group. Thus, this study extended the findings of previous studies indicating that perspective-taking abilities can be improved by an appropriate intervention program from early years (e.g., Aguero, 2013; Cigala, Mori, & Fangareggi, 2015; Geurts, Vanden-Abeele, Van-Keer, & Isenborghs, 2014; Grazzani & Ornaghi, 2011; Grizenko et al., 2000; Heagle & Rehfeldt, 2006; Khatchadourian, 2010; Laible & Song, 2006; Melot & Angeard, 2003; Ornaghi et al., 2011; Ping, 2005; Taş, 2017; Tenenbaum et al., 2008; Yagmur-Aras & Aslan, 2018). The findings of this study demonstrated that the activities in the program were effective in improvement of children’s perspective-taking abilities.…”
