title: Determinants of task performance and invested effort: a need for closure by relative cognitive capacity interaction analysis.
abstract: This study examines the simultaneous effects of need for closure (NFC) and relative cognitive capacity on invested effort and task performance within the integrative analysis framework using behavioral data. Two main results were obtained. First, the authors revealed a significant interaction effect between relative cognitive capacity (manipulated through task difficulty) and NFC (manipulated through time pressure, noise, and fear of invalidity as well as assessed by an individual differences measure) on effort investment. Second, contrary to dispositional NFC, manipulations yielded a "dual effect" because they negatively affected task performance as well as invested effort. The latter result was interpreted as an indication that noise and time pressure manipulations also tax cognitive resources. The two main findings are discussed and the authors go further into the divergences between dispositional and manipulated NFC.
