Source‐monitoring accuracy across repeated tests following directed forgetting

The repeated recall of items from lists that participants were earlier instructed to either remember or to forget was examined in two experiments. RR participants (those instructed to remember both lists they were presented) tended to recall more List 1 items than FR participants (those instructed to forget the first list and to remember the second list). FR participants recalled more List 2 items than did RR participants, but only when directed to report those items (Experiment 1), not when directed to report items from both lists (Experiment 2). Participants experienced difficulty correctly reporting the list source of items they recalled and incorrect source recall increased across tests, showing hypermnesia. This later result underscores the need for caution when assessing the accuracy of information retrieved from multiple sources across repeated tests. Together, the data patterns provide support for the retrieval dynamics account of hypermnesia, the context‐change account of directed forgetting, and limited support for the retrieval inhibition view of directed forgetting.     

Retrieval-induced forgetting in implicit memory tests: The role of test awareness

Retrieval practice with particular items in memory may result in decreased recall of different, semantically related, items. This retrieval-induced forgetting effect has been demonstrated in studies using explicit memory tests. Anderson and Spellman (1995) have attributed retrieval-induced forgetting to inhibitory mechanisms. This hypothesis predicts similar effects in implicit memory tasks. In our first experiment, using Anderson and Spellman’s original paradigm, retrieval-induced forgetting was found using an explicit memory test with independent extralist retrieval cues. In our second experiment, using the same materials, retrieval-induced forgetting was also found using an implicit memory test with independent extralist retrieval cues, but only for participants who were aware of the relationship between the study and practice phase on the one hand, and the test phase of the experiment on the other. Thus, test awareness seems to mediate retrieval-induced forgetting in implicit memory tasks.     

Attitude change in face‐to‐face and computer‐mediated communication: private self‐awareness as mediator and moderator

Two types of social influence can be distinguished: norm‐based influence occurs when social identity is salient and interpersonal influence occurs when personal identity is salient. In two experiments the impact of trait and state private self‐awareness on interpersonal influence during face‐to‐face and computer‐mediated communication (CMC) was investigated. It is argued that interpersonal influence resulting from face‐to‐face communication is stronger than interpersonal influence resulting from CMC because CMC heightens state private self‐awareness. As a result, it leads to a focus on personal perceptions and thoughts which in turn reduces attitude change. Experiment 1 suggests that communication media may influence attitude change via private self‐awareness. Experiment 2 showed that trait private self‐awareness moderates the effect of communication media on interpersonal influence. Interpersonal influence was stronger in face‐to‐face communication than in CMC only for individuals higher in private self‐awareness. This finding indicates that the impact of situational variations of a concept can be limited to individuals who have a more elevated sense of private self‐awareness.

Rhesus monkeys (<Emphasis Type="Italic">Macaca mulatta</Emphasis>) show robust evidence for memory awareness across multiple generalization tests

The possibility that memory awareness occurs in nonhuman animals has been evaluated by providing opportunity to decline memory tests. Current evidence suggests that rhesus monkeys (Macaca mulatta) selectively decline tests when memory is weak (Hampton in Proc Natl Acad Sci USA 98:5359–5362, 2001; Smith et al. in Behav Brain Sci 26:317–374, 2003). However, much of the existing research in nonhuman metacognition is subject to the criticism that, after considerable training on one test type, subjects learn to decline difficult trials based on associative learning of external test-specific contingencies rather than by evaluating the private status of memory or other cognitive states. We evaluated whether such test-specific associations could account for performance by presenting monkeys with a series of generalization tests across which no single association with external stimuli was likely to adaptively control use of the decline response. Six monkeys performed a four alternative delayed matching to location task and were significantly more accurate on trials with a decline option available than on trials without it, indicating that subjects selectively declined tests when memory was weak. Monkeys transferred appropriate use of the decline response under three conditions that assessed generalization: two tests that weakened memory and one test that enhanced memory in a novel way. Bidirectional generalization indicates that use of the decline response by monkeys is not controlled by specific external stimuli but is rather a flexible behavior based on a private assessment of memory.     

Segregation accuracy in item‐method directed forgetting across multiple tests

Two experiments examined recall across tests following item‐method directed‐forgetting instructions and the varying of presentation duration of items at study. For both immediate testing (Experiment 1) and delayed testing (Experiment 2), accurate recall of remember instruction items (R‐items) exceeded the accurate recall of forget instruction items (F‐items). However, some F‐items from study were inaccurately recalled as R‐items and R‐items from study as F‐items. Inaccurate recall persisted across tests for both immediate and delayed recall and increased across tests for immediate recall. We view the R‐item advantage in accurate recall as consistent with the account they receive more rehearsal at study than do F‐items. We view inaccurate recall as reflecting the bias to report items retrieved on an immediate test lacking instructional tags as F‐items. On delayed tests, items retrieved lacking instructional tags are first assessed against a criterion point on a memory‐strength continuum and those with strength above the criterion reported as R‐items and those below the criterion as F‐items.     

Maximizing the benefits and minimizing the costs of repeated memory tests for older adults

Repeatedly trying to remember information can help people remember more but can also lead to inaccuracies. Two experiments examined whether the costs of repeated recall efforts can be minimized for older adults by using memory tests that require specification of the source of recalled items. Participants saw and imagined pictures and then took 3 successive recall tests in which they either indicated the source of each remembered item (source recall) or simply recalled the items without specification of their source (free recall). Results showed that recall increased systematically from Test 1 to Test 3, although the rate of increase was less marked for older adults, and older adults recalled less overall. After the free recall tests, older adults made more source misattributions (claiming to have seen imagined items) than did young adults, but after the source recall tests, age differences were not significant. Thus, repeatedly recalling items while considering their source was associated with benefits in terms of increased recall and fewer costs in terms of source errors.     

Changes across age groups in self-choice elaboration and incidental memory

This study investigated differences in the self-choice elaboration and an experimenter-provided elaboration on incidental memory of 7- to 12-yr.-olds. In a self-choice elaboration condition 34 second and 25 sixth graders were asked to choose one of the two sentence frames into which each target could fit more congruously, whereas in an experimenter-provided elaboration they were asked to judge the congruity of each target to each frame. In free recall, sixth graders recalled targets in bizarre sentence frames better than second graders for self-choice elaboration condition. An age difference was not found for the experimenter-provided elaboration. In cued recall self-choice elaboration led to better performance of sixth graders for recalling targets than an experimenter-provided elaboration in both bizarre and common sentence frames. However, the different types of elaboration did not alter the recall of second graders. These results were interpreted as showing that the effectiveness of a self-choice elaboration depends on the subjects' age and the type of sentence.     

Changes across age groups in self-choice elaboration effects on incidental memory

The present study investigated age differences in the effects of a self-choice elaboration and an experimenter-provided elaboration on incidental memory. Adults, sixth grade, and second grade subjects chose which of two sentence frames the target fit better in a self-choice elaboration condition. They then judged whether each target made sense in its sentence frame in the experimenter-provided elaboration, then did free recall tests. Only adults recalled better the targets with an image sentence with self-choice elaboration, rather than experimenter-provided elaboration. However, self-choice elaboration was far superior for the recall of targets with nonimage sentences only for second graders. Thus, the effects of self-choice elaboration were determined both by age and by type of sentence frame.     

States of awareness across multiple memory tasks: obtaining a "pure" measure of conscious recollection

Four experiments were conducted to examine the nature of recollective experience across different explicit memory tests. Experiments 1 and 2 showed that the proportion of retrieved items that were given Remember responses were equivalent across free recall, category cued recall, category plus letter cued recall, and recognition memory tests unlike the result reported by Tulving [Can. Psychol. 26 (1985) 1]. Experiments 3 and 4 revealed that Remember judgments are influenced by both conceptual and perceptual variables not only in the recognition task but in other explicit memory tasks as well. Taken together, the empirical evidence from this study demonstrates that explicit memory performance is accompanied by different states of awareness not only in recognition but also across other memory tasks including free recall.     

Learning by Preparing‐to‐Teach and Teaching: A Meta‐Analysis

The present research meta‐analytically examined the effects of preparing‐to‐teach and subsequent teaching (relative to mere studying without teaching expectancy) on the acquisition of domain knowledge. The synthesis of 28 studies indicated that the estimated effect sizes (Hedges' gs) were 0.35 for preparing‐to‐teach and 0.56 for teaching with preparing‐to‐teach. Both preparing‐to‐teach and teaching with preparing‐to‐teach were effective in promoting deep learning (as well as surface learning) and even after a delay. The learning benefits of teaching with preparing‐to‐teach were larger when students expected and engaged in an interactive teaching activity than when they expected and engaged in a non‐interactive teaching activity. The mere expectation of interactive teaching also produced larger learning effects than the expectation of non‐interactive teaching. These results suggest that preparing‐to‐teach and teaching, interactive teaching after preparing to do so in particular, are useful for enhancing learning.     

The relationships between quantity‐number competencies,working memory,and phonological awareness in 5‐ and 6‐year‐olds

In this study, the interdependencies among phonological awareness, verbal working memory components, and early numerical skills in children 1 year before school entry are addressed. Early numerical skills were conceptualized as quantity‐number competencies (QNC) at both basic (QNC Level 1) and advanced (QNC Level 2) levels. In a sample of 1,343 children aged 5 and 6, structural equation modelling provided support for the isolated number words hypothesis (Krajewski & Schneider, 2009, J. Exp. Child Psychol., 103, 516–531). This hypothesis claims that phonological awareness contributes to the acquisition of QNC Level 1, such as learning the number word sequence, but not of QNC Level 2, which requires the linkage of number words to quantities. In addition, phonological awareness relied on verbal working memory, especially with regard to the phonological loop, central executive, and episodic buffer. The results were congruent with the idea that phonological awareness mediates the impact of verbal working memory on QNCs. The relationships between verbal working memory, phonological awareness, and QNCs were comparable in monolingual and bilingual children.     

Changes in the semantic constraint of spreading activation of memory across three age groups

28 undergraduate, 34 sixth-grade, and 36 second-grade students studied target words embedded in interchangeable or noninterchangeable sentences, and then performed free recall tests. In an interchangeable sentence the word which was to be remembered and its associated word fitted sensibly, whereas in a noninterchangeable sentence the target word fitted sensibly but its word associate did not. Undergraduates recalled the target words in noninterchangeable sentences better than sixth or second graders for whom a difference was not observed (undergraduates > sixth graders = second graders). In interchangeable sentences undergraduates recalled more targets than sixth or second graders, and sixth graders recalled more than second graders (undergraduates > sixth graders > second graders). The results were interpreted as indicating changes across age groups in the semantic constraint of spreading activation of target words in memory.     

Escape from rich‐to‐lean transitions: Stimulus change and timeout

Extended pausing during discriminable transitions from rich‐to‐lean conditions can be viewed as escape (i.e., rich‐to‐lean transitions function aversively). In the current experiments, pigeons’ key pecking was maintained by a multiple fixed‐ratio fixed‐ratio schedule of rich or lean reinforcers. Pigeons then were provided with another, explicit, mechanism of escape by changing the stimulus from the transition‐specific stimulus used in the multiple schedule to a mixed‐schedule stimulus (Experiment 1) or by producing a period of timeout in which the stimulus was turned off and the schedule was suspended (Experiment 2). Overall, escape was under joint control of past and upcoming reinforcer magnitudes, such that responses on the escape key were most likely during rich‐to‐lean transitions, and second‐most likely during lean‐to‐lean transitions. Even though pigeons pecked the escape key, they paused before doing so, and the latency to begin the fixed ratio (i.e., the pause) remained extended during rich‐to‐lean transitions. These findings suggest that although the stimulus associated with rich‐to‐lean transitions functioned aversively, pausing is more than simply escape responding from the stimulus.     

Behavioural Investigative Advice: Assistance to Investigative Decision‐making in Difficult‐to‐detect Murder

This paper considers the role of a Behavioural Investigative Adviser (BIA) in assisting with the decision‐making of a Senior Investigating Officer (SIO) in difficult‐to‐detect murder investigations. It outlines the need for transparent evidence‐based decision‐making from both the SIO and the BIA. The paper then details a piece of relevant, applied research that can assist in this end. The research utilised a pragmatic psychology approach to analyse 312 detected murder cases from the Serious Crime Analysis Section database. Some significant patterns relating what is known about the offence at different stages of an investigation and inferences regarding the offender were found, indicating that certain offence information can lead to some reliable predictions and these can be refined as more information becomes available. However, the findings also indicate that base rate frequencies and a ‘best‐guess’ methodology may be as, if not more, useful than more complex statistical techniques when providing advice to investigations.

Continuing Education in Motivational Interviewing for Addiction Counselors: Reducing the Research‐to‐Practice Gap

The authors evaluated the effectiveness of continuing education training in motivational interviewing (MI) for addiction counselors. Participants reported a significant increase in counseling self‐efficacy, and 87.5% reported increasing MI use in their practice. Only 3.8%, however, participated in posttraining consultation.     

The College‐to‐Career Transition: An Exploration of Emerging Adulthood

In this qualitative study, the authors explored the experience of recent college graduates transitioning from college to career within the first 3 years of their transition. Five men and 5 women were interviewed, and the narratives were analyzed using consensual qualitative research methodology. Several general themes emerged, including the role of social support, expectations, and optimism in adaptability and resilience in the college‐to‐career transition.
