Human Assessment: Cognition and Motivation
Similarly, interventions that affect motivation and effort should also affect cognitive performance. To this point, increasing dopaminergic transmission via amphetamine, which is well known to affect motivation and reward processing, has been shown to improve performance on cognitive tests.

In evaluating the present study, limitations should be mentioned. First, the measure used to assess intrinsic motivation was derived from the Heinrichs-Carpenter Quality of Life Scale rather than being a stand-alone measure. Recently, an intrinsic motivation inventory has been developed for and validated in patients with schizophrenia 84 ; we have used this specific measure in a previous study and the results are consistent with those presented herein. Although this measure included 3 distinct items and each demonstrated a relationship with cognitive performance, future studies should examine whether multiple indicators of motivation and effort eg, performance validity tests might explain a greater portion of variance in cognitive test performance.
Third, the relationship between change in intrinsic motivation and change in cognitive test performance, although statistically significant, was of a modest effect size. This effect may be owing in part to the relatively small improvement in cognition scores 51 and level of intrinsic motivation estimated mean difference, 0. Fourth, although the present results are interpreted as intrinsic motivation affecting cognitive performance scores, directionality cannot be established with the present set of analyses.
The possibility that cognitive impairment undermines volition remains. Finally, the influence of motivation and effort on cognitive test performance is not specific to individuals with schizophrenia 17 - 19 ; however, the prevalence of motivational deficits in this disorder suggests that this relationship may be particularly salient and ought to be taken into account.
The present results strongly encourage the assessment of variables such as motivation and effort when evaluating cognitive performance in schizophrenia. Taking these other variables into account may enhance the discovery of variables eg, genetic that are specifically related to core neurocognitive ability.
At the very least, our results suggest that poor cognitive test performance scores should not be inferred at face value to reflect impairment purely in neural processes subserving the cognitive process in question ie, neuroanatomical localization.
In addition, our findings suggest that in the ongoing search for therapeutics to improve functional outcomes among individuals with schizophrenia, a greater focus on motivational and effort-based deficits and their underlying neurobiology, or indeed the shared mechanisms underlying the motivation-cognition relationship, may facilitate efforts aimed at ameliorating these impairments and improving outcomes.
