“…In a second set of analyses, we used a quasi-signal detection approach (QSDT ; e.g., Gable, Reis, & Downey, 2003) to examine the influences of communal motives on the perception of specific communal and uncommunal partner behaviors. Although signal detection analyses are primarily used in experimental research (Macmillan & Creelman, 2005), they are increasingly adopted in naturalistic studies (e.g., Henry, Kobus, & Schoeny, 2011;Mast, Hall, & Ickes, 2006;McClure, Lydon, Baccus, & Baldwin, 2010). Prior research has primarily used QSDT analyses to examine the consequences of partner perceptions for relationship functioning (Finkenauer, Wijngaards-de Meij, Reis, & Rusbult, 2010;Gable et al, 2003;Reis, Maniaci, & Rogge, 2014, 2017Visserman et al, 2018), whereas the present research addressed its motivational sources.…”
