Research regarding how people monitor their learning has shown that ease of processing strongly guides people's judgments of learning (JOLs). However, the desirable difficulties concept (Bjork, 1994) suggests that studying information that is less fluent can result in greater learning. Currently, it is unclear whether people are aware of the potential benefits of desirable difficulties during learning. To address this, in Experiment 1, participants studied inverted and upright words and also made JOLs. While participants' JOLs did not differ for inverted and upright words, recall was greater for inverted words. Experiment 2 used several study-test cycles in which participants could potentially learn about the beneficial effects of processing inverted words with task experience, and similar results were obtained. Thus, reading inverted words requires processing that enhances recall, but memory predictions do not differentiate between upright and inverted words. We interpret these results in terms of processing fluency, desirable difficulties, and theories of metacognitive monitoring.

It is often necessary to selectively attend to important information, at the expense of less important information, especially if you know you cannot remember large amounts of information. The present study examined how younger and older adults select valuable information to study, when given unrestricted choices about how to allocate study time. Participants were shown a display of point values ranging from 1-30. Participants could choose which values to study, and the associated word was then shown. Study time, and the choice to restudy words, was under the participant's control during the 2-minute study session. Overall, both age groups selected high value words to study and studied these more than the lower value words. However, older adults allocated a disproportionately greater amount of study time to the higher-value words, and age-differences in recall were reduced or eliminated for the highest value words. In addition, older adults capitalized on recency effects in a strategic manner, by studying high-value items often but also immediately before the test. A multilevel mediation analysis indicated that participants strategically remembered items with higher point value, and older adults showed similar or even stronger strategic process that may help to compensate for poorer memory. These results demonstrate efficient (and different) metacognitive control operations in younger and older adults, which can allow for strategic regulation of study choices and allocation of study time when remembering important information. The findings are interpreted in terms of life span models of agenda-based regulation and discussed in terms of practical applications.

Tests, as learning events, are often more effective than are additional study opportunities, especially when recall is tested after a long retention interval. To what degree, though, do prior test or study events support subsequent study activities? We set out to test an implication of Bjork and Bjork's (1992) new theory of disuse-that, under some circumstances, prior study may facilitate subsequent study more than does prior testing. Participants learned English-Swahili translations and then underwent a practice phase during which some items were tested (without feedback) and other items were restudied. Although tested items were better recalled after a 1-week delay than were restudied items, this benefit did not persist after participants had the opportunity to study the items again via feedback. In fact, after this additional study opportunity, items that had been restudied earlier were better recalled than were items that had been tested earlier. These results suggest that measuring the memorial consequences of testing requires more than a single test of retention and, theoretically, a consideration of the differing status of initially recallable and nonrecallable items.

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 itemmethod 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. Participants studied words, each of which was followed by a cue to remember (R) or forget (F) the word for an upcoming test, and also made predictions of how likely they would be to later recall each word. When asked to recall all of the words, regardless of cue, both recall and predicted recall were fairly sensitive to the R or F instructions, despite some overconfidence. 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.

Reaction times were collected for three observers in a YES-NO signal detection experiment, for two different signal strengths, and three a priori probabilities of a signal occurrence—P (S): 0.2, 0.5, and 0.8. Each server gave 1800 responds under each of the six conditions. A trial ended only when the observer terminated it. Some of the major findings are (1) latencies have Pearson distributions, mainly Beta of the first and second kind; (2) there is an apparent genetic character to the distributions—that is, they resemble each other according to the response (YES or NO) rather than the stimulus (signal or noise alone); (3) at P (S) = 0.2, the mean latency of a false rejection of a signal is least, that of a correct detection greatest, but for P (S) = 0.5, and 0.8, mean latency is least for correct detection, and greatest for correct NO'S, and (4) generally, reaction times are inversely related to the a priori probability of their associated stimulus classes.
