“…People with higher DASS scores thought they did worse on the parity task, but objective performance was unaffected. Many tests of motivational intensity theory find correlations between physiological markers of effort and behavioral measures of performance (e.g., Silvia, McCord, & Gendolla, 2010); many more studies, including most of our group’s studies, find only weak or null correlations with performance (e.g., Silvia, Jones, Kelly, & Zibaie, 2011a, 2011b; Silvia, Kelly, Zibaie, Nardello, & Moore, 2013; Silvia, Moore, & Nardello, in press). How hard people try and how well they actually do are quite different.…”
