If the beneficial effect of refreshing on memory performance is due to the information being selected for refreshing (i.e., selection hypothesis), a constant memory boost is expected to occur each time an item is selected for refreshing, with better memory performance for items that are selected more often. If, however, the beneficial effect of refreshing on memory performance is due to spending time in the focus of attention during refreshing (i.e., duration hypothesis), a gradual memory boost is expected, with the size of the memory boost being a direct function of how long the item has been the object of focused attention. To distinguish between these hypotheses, we instructed and guided the use of refreshing during retention through the presentation of cues, and varied the number of refreshing steps and their duration independently. The number of refreshing steps, but not their duration, had an effect on recall, in agreement with the selection hypothesis.

Given that scene perception involves extraction of contextual associations, we hypothesized that associative thought would enhance scene memory by promoting encoding of contextual associations. In an online experiment (N = 75), participants viewed scenes, and following each scene either generated chained-free associations (associative processing), or, as control, listed words that begin with a specific letter (phonological processing). Scene memory was tested after an intermediate creativity task, which is also shown to rely on associative processes. Results revealed that associative thought, regardless of its conceptual (semantic) distances between responses, enhanced scene-gist memory, but hampered memory of scene details, implying that associative thought facilitates contextual encoding. In a follow-up experiment (N = 74), we found that the effect of associative thought on scene-gist memory was mediated by scene labeling. When participants were asked to explicitly label the scene before completing an associative processing or a phonological processing task, scene-gist memory was prioritized at the expense of scene details, eliminating the memory differences between tasks. These findings imply that labeling past perceived scenes, whether explicitly or implicitly during associative thought, facilitates scene-gist memory. Lastly, in both experiments, creativity was not correlated with scene memory but was positively correlated with the semantic distances between scene-based associations, extending past findings that link creativity with the breadth of associative processes. Together, these findings highlight the likely effect of post-perceptual associative processes on higher-order cognitive functions, such as memory consolidation and creative thought.</p>","PeriodicalId":48398,"journal":{"name":"Memory & Cognition","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142773795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We first replicate the observed effect within the visual domain (Experiment 1) and subsequently extend it to the verbal domain (Experiment 2).

In Experiment 1, twenty-four healthy young adults, and in Experiment 2, thirty-six participants, performed the SRTT with congruent (same position), incongruent (different position), or neutral (no prime) subliminal masked primes. Each condition featured an embedded eight-digit (Experiment 1) or ten-digit (Experiment 2) second-order sequence, with conditions presented in counterbalanced order during a single session. Sequence specific learning was observed under neutral and congruent prime conditions. Independent of sequence awareness, congruent primes reduced initial response latency and led to greater sequence specific learning compared with neutral primes. However, incongruent primes appeared to attenuate learning (Experiment 1). These results demonstrate that prime congruency modulates sequence specific learning below the threshold of conscious awareness. Congruent primes may elevate the salience of stimulus-response compounds and accentuate learning, but at the cost of increased awareness. Incongruent primes, and the induction of response conflict, attenuate sequence specific learning (Experiment 1) and may prevent the formation of cross-temporal contingencies necessary for implicit motor sequence learning.</p>","PeriodicalId":48398,"journal":{"name":"Memory & Cognition","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142683088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted two experiments to measure event completion in macro-events presenting portions of multiple micro-events. In Experiment 1, video summaries were formed with or without event boundary information where a macro-end was either present or absent. Macro-end signified an overarching goal achievement that signaled the completion of previous tasks (such as leaving the kitchen with a full breakfast plate). More completion occurred for summaries with event boundary information and macro-ends. In Experiment 2, we tested two alternative hypotheses to explore the underlying process by showing the beginnings or ends of a micro-event. While the predictive processing hypothesis suggests that event completion is based more on predicting the future states of the event based on beginning information, the backward inferences hypothesis suggests that event completion relies more on deductions formed after the fact based on event endings.

Earlier studies indicate that certain positive effects (i.e., the testing effect) are not reduced by distraction, whereas negative effects (i.e., RIF) are eliminated. The present study assessed an indirect (positive) effect of retrieval-the forward testing effect (FTE), in which prior retrieval or retrieval attempts enhance subsequent learning. Two experiments examined the role of attention in both the standard FTE and the pretesting effect. In Experiment 1, participants learned three study lists through retrieval practice or restudy, followed by a fourth study list. Prior retrieval practice enhanced subsequent new learning more than restudy (i.e., the standard FTE), and to a similar degree under full attention (FA) and divided attention (DA). In Experiment 2, participants learned cue-target word pairs by either studying the pair or guessing the target when shown a cue (i.e., pretesting) followed by the correct pair. Pretesting enhanced memory more than just studying to a similar degree under FA and DA.

Recent work suggests that using fillers who match the basic characteristics of the perpetrator (e.g., same age, race, and gender) but who are otherwise maximally dissimilar to the suspect optimizes discriminability. However, the optimal lineup size has been found to vary with filler similarity, with larger lineup sizes increasing or decreasing discriminability depending on whether low-similarity or high-similarity fillers were used, respectively. Because manipulating filler similarity at retrieval affects overall performance, here we investigated whether encoding manipulations that affect overall performance also affect how lineup size influences discriminability. In three experiments, we first replicated prior findings (N = 502), then reduced encoding strength by making study images blurry when low-similarity fillers were used (N = 553), and finally increased encoding strength by repeating study images when high-similarity fillers were used (N = 501). We found that whether overall performance was low or high due these encoding manipulations, discriminability still increased as a function of lineup size when low-similarity fillers were used and decreased as a function of lineup size when high-similarity fillers were used.
