The purpose of this study was to thoroughly review previous work and to create a new experimental paradigm combining recognition memory with value-based incentives and metacognitive confidence judgments, which may provide convergent evidence for the motivation-cognition interface. This paradigm involves a game-like task administering global and local motivational incentives. Furthermore, trial-level metacognitive confidence ratings were gathered to understand the relationship of metacognitive accuracy and value as a function of strategic control of attention and memory and incentive-based motivation. Paired samples t-tests and a repeated measures ANOVA were used to identify differences in recognition performance based on reward incentive, and Goodman-Kruskall gamma correlations between performance confidence estimates were used to measure metacognitive accuracy. The results showed the mean number of recognition hits (correctly remembering previously seen items) were indeed greater for high-value items compared to low-value items. I also report an unanticipated effect of block, such that the hit rate increased for low valued items from Block 1 to Block 2. Unfortunately, I did not find meaningful results for the metacognitive judgments. This study lays important groundwork for subsequent research incorporating physiological testing to provide a much-needed link between mind and brain with respect to motivation and cognition. Moreover, this study provides important evidence about limitations within the current design and of remote experimental testing broadly.
