Past research has evaluated participants' understanding of their memory by soliciting judgments of learning (JOLs). Importantly, JOLs sometimes change memory for the judged material, leading to JOL reactivity. The cue-strengthening account (Soderstrom et al., 2015) and changed-goal account (Mitchum et al., 2016) propose different mechanisms that lead to JOL reactivity. In the present study, we collected measures that can provide further insight into these mechanisms. Specifically, participants studied related and unrelated word pairs in different colored fonts for a source recognition test. Across three experiments, data were analyzed using a hierarchical Bayesian model of multidimensional source memory to determine how JOLs impact item memory as well as relatedness and color source memory. In Experiment 2, we also compared the effects of making JOLs to making judgments of relatedness (JORs), and Experiment 3 examined how JOLs impact study time allocation. The results of our experiments failed to fully follow predictions of either account. Making JOLs (Experiments 1-3) and JORs (Experiment 2) strengthened item memory for related as well as unrelated pairs, the latter finding not predicted by either account. In addition, JOLs and JORs did not specifically strengthen source memory for relatedness, as the cue-strengthening account predicts, nor did JOLs change study time (Experiment 3), as suggested by the changed-goal account. In all, our results provide novel insight that enhanced item memory may be largely responsible for JOL reactivity, thus adjudicating between candidate explanations.

E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
