Comparative Study
Are we aware of our ability to forget? Metacognitive predictions of directed forgetting.
It is often important to accurately predict not only what information we will later remember, but also what information we are likely to forget. The present research examined these abilities in the context of item-method directed forgetting, to determine whether people are aware of their strategic control of remembering and forgetting, as well as what cues are used when making metacognitive judgments. ⋯ A similar and stronger pattern was found when words were assigned positive or negative point values as cues to remember or forget. These findings suggest that item-based cues to remember or forget information can be successfully utilized when making metacognitive judgments, and that people are fairly aware of the control they have over both remembering and forgetting information.

Dual-process theories of retrieval suggest that controlled and automatic processing contribute to memory performance. Free recall tests are often considered pure measures of recollection, assessing only the controlled process. We report two experiments demonstrating that automatic processes also influence free recall. ⋯ Results from both methods indicated that free recall is partly driven by automatic processes. Thus, we conclude that retrieval in free recall tests is not driven solely by conscious recollection (or remembering) but also by automatic influences of the same sort believed to drive priming on implicit memory tests. Sometimes items come to mind without volition in free recall.

Does familiarity arise from direct access to memory representations (a mnemonic account) or from inferences and diagnostic cues (an attributional account)? These theoretically distinct explanations can be difficult to distinguish in practice, as is shown by the positivity effect, the increase in feelings of familiarity that accompanies positive emotion. Experiment 1 manipulated mnemonic and attributional sources of positivity via word valence and physical expressions of emotion, respectively. ⋯ To further contrast the mnemonic and attributional accounts, Experiment 2 varied the ratio of positive to neutral words. A higher proportion of positive words exaggerated the pattern of increased old judgments and decreased accuracy for positive words, relative to neutral ones, consistent with the mnemonic account but inconsistent with the attributional account.

When making source attributions, people tend to attribute desirable statements to reliable sources and undesirable statements to unreliable sources, a phenomenon known as the wishful thinking effect (Gordon, Franklin, & Beck, 2005). In the present study, we examined the influence of wishful thinking on source monitoring for self-relevant information. On one hand, wishful thinking is expected, because self-relevant desires are presumably strong. ⋯ In Experiment 1, source memory for self-relevant information was contrasted against source memory for information relevant to others and for neutral information. Results indicated that self-relevant information was affected by wishful thinking and was remembered more accurately than was other information. Experiment 2 showed that the magnitude of the self-relevant wishful thinking effect did not increase with a delay.

How do readers deal with information that is inconsistent with what they know? This question has typically been addressed by examining whether carefully designed texts can help readers revise inaccurate beliefs. However, texts sometimes present incorrect information that runs counter to readers' accurate knowledge. Three experiments were performed to examine how individuals process incorrect information during reading. ⋯ This pattern held even with a task that encouraged readers to consider their prior knowledge. Story contexts were particularly influential when modified to present novel scenarios. These results provide insight into the role of prior knowledge when readers encounter incorrect information, and into the consequences of such experiences.
