Comparing recollection and nonrecollection memory states for recall of general knowledge: A nontrivial pursuit.

Based on the classic distinction between semantic and episodic memory, people answer general-knowledge questions by querying their semantic memory. And yet, an appeal of trivia games is the variety of memory experiences they arouse-including the recollection of episodic details. We report the first in-depth exploration of the memory states that arise for recalled answers to general-knowledge questions. In 2 experiments, participants classified their answers as learning memory or related memory forms of recollection, as feels familiar or just know forms of nonrecollection, or as a guess. A recollection state was reported for nearly half of the correct answers. Learning memory, related memory, and just know states showed similarly high accuracy and confidence-whereas the feels familiar state was much lower. The differences between familiarity and knowing highlight the importance of distinguishing these oft-conflated states. Our study establishes that episodic memory often contributes to retrieval of general-knowledge, and that the memory states arising during retrieval can be diagnostic of accuracy.

Protective effects of testing across misinformation formats in the household scene paradigm.

Many studies have demonstrated retrieval-enhanced suggestibility (RES), in which taking an initial recall test after witnessing an event increases suggestibility to subsequent misinformation introduced via a narrative. Recently, however, initial testing has been found to have a protective effect against misinformation introduced via cued-recall questions. We examined whether misinformation format (narrative vs. cued-recall questions) yields a similar dissociation in a paradigm that, to date, has consistently yielded a protective effect of testing (PET). After studying photos of household scenes (e.g., kitchen), some participants took an initial recall test. After a 48-hr delay, items not presented in the scenes (e.g., knives/plates) were suggested either via narrative or questions. Regardless of the misinformation format, we found a PET on both initial-test-conditionalised free recall and source-monitoring tests. However, initial testing also yielded memory costs, such that suggested items reported on the initial test were likely to persist on a final recall test. Thus, initial testing can protect against suggestibility, but can also precipitate memory errors when intrusions emerge on an initial test.

First episode indices associated with lifetime chronicity of depression among formerly depressed participants: an exploratory study.

Background: Researchers have found that an earlier age of disorder onset and the severity of the first depressive episode are associated with recurrence in depression. Additionally, neuroticism has been shown to be an important factor in the recurrence of the disorder.Aims: This exploratory study aimed to replicate and extend previous research by examining the relationships between features of the first experienced depressive episode (age of onset, severity), the five factors of personality, and lifetime chronicity of depression.Method: Forty-three previously depressed participants completed measures of personality, current depression, hopelessness, and perfectionism. Previous depressive episodes were assessed using a semi-structured interview, and features of these episodes experienced by participants were recorded.Results: Pearson correlations showed that depression chronicity, measured in the number of weeks depressed in a lifetime, was significantly correlated with age of onset and number of symptoms experienced in the first episode. Personality measures were not significantly associated with depression chronicity.Conclusion: Earlier and more severe first episodes of depression may play an important role in the recurrence of the disorder. Future research should focus on replication and determining the causal role of these features.

Depression and Depressive Symptoms in Pediatric Traumatic Brain Injury: A Scoping Review.

OBJECTIVE: This scoping review aimed to summarize the existing knowledge base regarding depression and depressive symptoms in pediatric traumatic brain injury (TBI) and to identify gaps in the literature in an effort to guide future research. METHODS: MEDLINE Ovid and PsycINFO Ovid databases were each searched by the authors using search terms intended to identify any original research study that examined depressive symptoms in children (ie, aged 0-18 years) with TBI. RESULTS: A total of 14 published studies were included in the review. The studies included examined the prevalence of depression, risk factors associated with depression, and depression as a predictor of other TBI-related outcomes. CONCLUSION: Existing research suggests that depressive symptoms are more common in a TBI population than in a healthy or orthopedically injured population. Injury-related factors such as lesions in the brain and the presence of pain, as well as noninjury factors such as older age at injury and low socioeconomic status, may be predictive of depressive symptoms. Depression is likely a secondary outcome of pediatric TBI rather than a direct result of the injury itself. Overall, a relative dearth of research exists on this topic; thus, the review concludes by proposing future research directions.

Short-term reliability of a brief hazard perception test.

Hazard perception tests (HPTs) have been successfully implemented in some countries as a part of the driver licensing process and, while their validity has been evaluated, their short-term stability is unknown. This study examined the short-term reliability of a brief, dynamic version of the HPT. Fifty-five young adults (Mage=21 yrs) with at least two years of post-licensing driving experience completed parallel, 21-scene HPTs with a one-month interval separating each test. Minimal practice effects (∼0.1s) were manifested. Internal consistency (Cronbach's alpha) averaged 0.73 for the two forms. The correlation between the two tests was 0.55 (p<0.001) and correcting for lack of reliability increased the correlation to 0.72. Thus, a brief form of the HPT demonstrates acceptable short-term reliability in drivers whose hazard perception should be stable, an important feature for implementation and consumer acceptance. One implication of these results is that valid HPT scores should predict future crash risk, a desirable property for user acceptance of such tests. However, short-term stability should be assessed over longer periods and in other driver groups, particularly novices and older adults, in whom inter-individual differences in the development of hazard perception skill may render HPT tests unstable, even over short intervals.
