The SDT literature is replete with experimental (e.g., Benita, Shane, Elgali, & Roth, ; Deci et al, ; Wuyts, Vansteenkiste, Mabbe, & Soenens, ), longitudinal (e.g., Mageau et al, ), and experience‐sampling studies (Ryan, Bernstein, & Brown, ; Thomaes, Sedikides, van den Bos, Hutteman, & Reijntjes, ), and SDT studies make use of a variety of “third person” and non‐self‐report methods including behavior observations (e.g., Ahmad, Vansteenkiste, & Soenens, ; Haerens et al, ), (neuro)physiological assessments (e.g., Reeve & Tseng, ), priming procedures (e.g., Radel, Sarazin, & Pelletier, ; Weinstein, Hodgins, & Ryan, ), and implicit measures (e.g., Ryan & Grolnick, ; Van Assche, Van der Kaap‐Deeder, De Schryver, Audenaert, & Vansteenkiste, ).
