The effects of free recall testing on subsequent source memory

The testing effect is the finding that prior retrieval of information from memory will result in better subsequent memory for that material. One explanation for these effects is that initial free recall testing increases the recollective details for tested information, which then becomes more available during a subsequent test phase. In three experiments we explored this hypothesis using a source-monitoring test phase after the initial free recall tests. We discovered that memory is differentially enhanced for certain recollective details depending on the nature of the free recall task. Thus further research needs to be conducted to specify how different kinds of memorial details are enhanced by free recall testing.     

Receiving right/wrong feedback: Consequences for learning

Prior work suggests that receiving feedback that one's response was correct or incorrect (right/wrong feedback) does not help learners, as compared to not receiving any feedback at all (Pashler, Cepeda, Wixted, & Rohrer, 2005). In three experiments we examined the generality of this conclusion. Right/wrong feedback did not aid error correction, regardless of whether participants learned facts embedded in prose (Experiment 1) or translations of foreign vocabulary (Experiment 2). While right/wrong feedback did not improve the overall retention of correct answers (Experiments 1 and 2), it facilitated retention of low-confidence correct answers (Experiment 3). Reviewing the original materials was very useful to learners, but this benefit was similar after receiving either right/wrong feedback or no feedback (Experiments 1 and 2). Overall, right/wrong feedback conveys some information to the learner, but is not nearly as useful as being told the correct answer or having the chance to review the to-be-learned materials.     

Focused attention on one contextual attribute does not reduce source memory for a different attribute

In three experiments, participants were asked to learn a particular contextual dimension of a study episode for a later memory test. The hypothesis being evaluated was that focused attention towards learning a particular source‐specifying attribute would decrease memory for a different attribute dimension. Although source memory for the attribute dimensions in the focus of attention were generally improved, memory was not diminished for contextual attributes ostensibly outside the focus of primary attention. The absence of any decrease in memory appears to be a somewhat general phenomenon because it was found with external–external, internal–external, and internal–internal combinations of attribute dimensions. The results may be most consistent with a model of cognitive processing in which people have separate pools of attentional resources rather than a single pool of general resources.     

What Happens to Physical Activity Behavior,Motivation, Self-Concept,and Flow After Completing School? A Longitudinal Study

With particular focus on the year following completion of high school, the present study sought to establish the status of young people's physical activity behavior, physical activity motivation, physical activity flow, and physical self-concept. Among a sample of 213 Australian participants assessed in their final year of school and then one year later, findings suggested a significant increase in physical activity behavior and a significant reduction in maladaptive behavioral motivation. On other physical measures, females demonstrated significant improvements in their general physical self-concepts and males demonstrated significant improvements in their health self-concepts. Implications for gender-specific and developmentally targeted interventions are discussed.     

Metacognitive-like information seeking in lion-tailed macaques: a generalized search response after all?

Previous research has demonstrated that Old World primates (both apes and monkeys) seek information about the location of a hidden food item, unless they are privy to the hiding process. This has been cited as evidence of metacognition. However, these results could also be interpreted using non-metacognitive accounts, including a generalized search response to uncertainty, in which subjects reach for food when it is seen, or search for food until it is spotted. In the present research, lion-tailed macaques were tested on an object-choice task. Conditions varied with respect to the visibility of the baiting process, and whether the location of the hidden food could be inferred by logical exclusion. Additionally, the hidden food could be located visually before a choice was made, by peering under the objects through a Plexiglas tray. Across conditions, monkeys consistently looked for the food when it had not been seen, even if its location could be inferred, despite the fact that these monkeys are capable of inference by exclusion. This suggests that apparently ‘metacognitive’ information seeking in monkeys may instead reflect a generalized search strategy. Alternatively, it is possible that monkeys only have metacognitive access to certain types of knowledge, including that obtained visually. Results are discussed with respect to the likelihood of metacognition in this species and the evolutionary emergence of metacognition across species.     

Quality of Life Assessments,Cognitive Reliability,and Procreative Responsibility

Recent work in the psychology of happiness has led some to conclude that we are unreliable assessors of our lives and that skepticism about whether we are happy is a genuine possibility worth taking very seriously. I argue that such claims, if true, have worrisome implications for procreation. In particular, they show that skepticism about whether many if not most people are well positioned to create persons is a genuine possibility worth taking very seriously. This skeptical worry should not be confused with a related but much stronger version of the argument, which says that all human lives are very bad and not worth starting. I criticize the latter stance, but take seriously the former stance and hope it can be answered in future work.     

Boundaries of semantic distraction: Dominance and lexicality act at retrieval

Three experiments investigated memory for semantic information with the goal of determining boundary conditions for the manifestation of semantic auditory distraction. Irrelevant speech disrupted the free recall of semantic category- exemplars to an equal degree regardless of whether the speech coincided with presentation or test phases of the task (Experiment 1), and this occurred regardless of whether it comprised random words or coherent sentences (Experiment 2). The effects of background speech were greater when the irrelevant speech was semantically related to the to-be-remembered material, but only when the irrelevant words were high in output dominance (Experiment 3). The implications of these findings in relation to the processing of task material and the processing of background speech are discussed.     

The Role of Interruptions and Contextual Associations in Delayed‐Execute Prospective Memory

We conducted three experiments to examine the dynamics of a delayed‐execute prospective memory task involving task interruptions. In the delayed‐execute paradigm, participants must delay a response until some future condition is met. After an intention was formed to a salient cue, an interruption reduced prospective memory relative to a no‐interruption condition. Prospective memory for cues encountered during an interrupting task was worse than for cues occurring before an interruption, but the location of the cue in either the ongoing task or the interruption did not affect prospective memory. Importantly, reinstating the prevailing context after the interruption alleviated the negative influence of the interruption. Providing participants with information about the future context for making the delayed‐execute response also alleviated some of these deficits presumably because participants could encode more specific features of the performance context. These results highlight the potential importance of contextual associations and reminders in completing everyday intentions successfully. Copyright © 2013 John Wiley & Sons, Ltd.
