The influence of imagery vividness and internally-directed attention on the neural mechanisms underlying the encoding of visual mental images into episodic memory.

Cereb Cortex 2022 Aug 10. Epub 2022 Aug 10.

Department of Psychology and Neuroscience, Duke University, Durham, NC 27708, United States.

Attention can be directed externally toward sensory information or internally toward self-generated information. Using electroencephalography (EEG), we investigated the attentional processes underlying the formation and encoding of self-generated mental images into episodic memory. Participants viewed flickering words referring to common objects and were tasked with forming visual mental images of the objects and rating their vividness. Read More

Repeated series learning revisited with a novel prediction on the reduced effect of item frequency in dyslexia.

Sci Rep 2022 Aug 8;12(1):13521. Epub 2022 Aug 8.

The Edmond and Lily Safra Center for Brain Sciences, The Hebrew University of Jerusalem, Jerusalem, Israel.

Developmental dyslexia, a difficulty with acquiring fluent reading, has also been characterized by reduced short-term memory (STM) capacity, which is often operationalized with span tasks. The low performance of individuals with dyslexia (IDDs) in such tasks is commonly attributed to poor phonological memory. However, we suggest an alternative explanation based on the observation that many times the items that are used in spans tasks are high-frequency items (e. Read More

Development of the function of autobiographical memories evoked by odor scale for older Japanese people.

Front Psychol 2022 22;13:945002. Epub 2022 Jul 22.

Faculty of Human Studies, Bunkyo Gakuin University, Tokyo, Japan.

Odor-evoked autobiographical memory and related psychological changes have been evaluated based on several factors, such as emotionality, clarity, and re-experience. We developed the Function of Autobiographical Memories Evoked by Odor Scale (FAMOS) for older Japanese people as a new method for comprehensively evaluating the functions of odor-evoked autobiographical memory. We used the diary method; participants were instructed to record the contents of everyday involuntary autobiographical memories triggered by odor and complete the FAMOS. Read More

Common neural mechanisms control attention and working memory.

J Neurosci 2022 Aug 4. Epub 2022 Aug 4.

Program in Psychology, New York University Abu Dhabi, Abu Dhabi, UAE

Although previous studies point to qualitative similarities between working memory (WM) and attention, the degree to which these two constructs rely on shared neural mechanisms remains unknown. Focusing on one such potentially shared mechanism, we tested the hypothesis that selecting an item within WM utilizes similar neural mechanisms as selecting a visible item via a shift of attention. We used fMRI and machine learning to decode both the selection among items visually available and the selection among items stored in WM in human subjects (both sexes). Read More

Arousal-modulated memory encoding and retrieval in adults with autism spectrum disorder.

Autism Res 2022 Jul 30. Epub 2022 Jul 30.

Autism Research Group, Department of Psychology, City, University of London, London, UK.

Recently, we have shown that pupil dilation during a recognition memory task can serve as an index of memory retrieval difficulties in autism. At the time of publication, we were unaware of specific data-analysis methods that can be used to shed further light on the origins of such memory related pupil dilation. Specifically, by distinguishing "tonic" from "phasic" changes in pupil dilation and considering their temporal progression, it is possible to draw inferences about the functional integrity of a locus coeruleus-norepinephrine system (LC-NE) that is known to play a key role in regulating memory encoding and retrieval processes.

Study effort and the memory cost of external store availability.

Cognition 2022 Jul 26;228:105228. Epub 2022 Jul 26.

University of Waterloo.

Previous work demonstrates that individuals often recall less information if, at study, there is expectation that an external memory store will be available at test. One explanation for this effect is that when individuals can expect access to an external memory store, they forgo intentional, controlled efforts at encoding. The present work offers a novel test of this account by examining study effort, indexed by study time and self-reported strategy use, as a function of instructed external store availability.

Test-retest reliability for common tasks in vision science.

J Vis 2022 Jul;22(8):18

Aston University, School of Psychology, College of Health & Life Sciences, Birmingham, UK.

Research in perception and attention has typically sought to evaluate cognitive mechanisms according to the average response to a manipulation. Recently, there has been a shift toward appreciating the value of individual differences and the insight gained by exploring the impacts of between-participant variation on human cognition. However, a recent study suggests that many robust, well-established cognitive control tasks suffer from surprisingly low levels of test-retest reliability (Hedge, Powell, & Sumner, 2018b). Read More

Episodic Memory and Schizophrenia: From Characterization of Relational Memory Impairments to Neuroimaging Biomarkers.

Curr Top Behav Neurosci 2022 Jul 29. Epub 2022 Jul 29.

Douglas Research Centre, Verdun, QC, Canada.

Episodic memory research in schizophrenia has a long history already which has clearly established significant impairments and strong associations with brain measures and functional outcome. The purpose of this chapter is not to make an exhaustive review of the recent literature but to highlight some relatively recent developments in the cognitive neuroscience field of episodic memory and schizophrenia. Hence, we present a contemporary view focusing specifically of relational memory which represents a form of episodic memory that refers to associations or binding among items or elements presented together.

The formation of specific and gist associative episodic memory representations during encoding: Effects of rate of presentation.

J Exp Psychol Learn Mem Cogn 2022 Jul 28. Epub 2022 Jul 28.

Department of Psychological Sciences.

Assessing the time course under which underlying memory representations can be formed is an important question for understanding memory. Several studies assessing item memory have shown that gist representations of items are laid out more rapidly than verbatim representations. However, for associations among items/components, which form the core of episodic memory, it is unclear whether gist representations form more quickly than, or at least in parallel with, verbatim representations, as fuzzy-trace theory predicts, or whether gist is extracted more slowly from inferring the meaning of verbatim representations, as in gist macroprocessor theories.

Intent matters: Resolving the intentional versus incidental learning paradox in episodic long-term memory.

J Exp Psychol Gen 2022 Jul 28. Epub 2022 Jul 28.

Department of Psychology.

Decades of research have established that the intent to remember information has no effect on episodic long-term memory. This claim, which is routinely taught in introductory cognitive psychology courses, is based entirely on pure-list between-subjects designs in which memory performance is equal for intentional and incidental learning groups. In the current 11 experiments, participants made semantic judgements about each word in a list but they had to remember only words presented in a specific color. Read More

EXPRESS: Attention Allocation Between Item and Order Information in Short-Term Memory.

Q J Exp Psychol (Hove) 2022 Jul 28:17470218221118451. Epub 2022 Jul 28.

University of Missouri, Psychological Sciences, Columbia, Missouri, United States 14716.

In immediate memory for verbal lists, recently it has been shown that participants can choose to carry out encoding that prioritizes readiness for an item test at some cost to order information or, conversely, that prioritizes readiness for an order test at a cost to item information (Guitard et al., 2021, 2022). Here we ask whether participants can control attention to items and order in a graded fashion. Read More

A Model of Semantic Completion in Generative Episodic Memory.

Neural Comput 2022 Jul 19:1-30. Epub 2022 Jul 19.

Institute for Neural Computation, Faculty of Computer Science, Ruhr University Bochum, 44801 Bochum, Germany

Many studies have suggested that episodic memory is a generative process, but most computational models adopt a storage view. In this article, we present a model of the generative aspects of episodic memory. It is based on the central hypothesis that the hippocampus stores and retrieves selected aspects of an episode as a memory trace, which is necessarily incomplete. Read More

Long-term memory retrieval bypasses working memory.

Neuroimage 2022 Jul 23;261:119513. Epub 2022 Jul 23.

Key Laboratory of Brain, Cognition and Education Sciences (South China Normal University), Ministry of Education, China; Institute for Brain Research and Rehabilitation, South China Normal University, China; Center for Studies of Psychological Application, South China Normal University, China; Guangdong Key Laboratory of Mental Health and Cognitive Science, South China Normal University, China. Electronic address:

For decades, it has been assumed that when humans retrieve information from long-term memory (LTM), information need first to be brought back into working memory (WM). However, as WM capacity is limited, it is unclear what happens if information from LTM needs to be retrieved while WM is fully engaged? To address this question, observers had to retrieve colors from LTM while WM storage capacity was fully engaged. The behavioral results showed that retrieving information from LTM is possible even when WM capacity is fully occupied. Read More

Temporal order memory impairments in individuals with moderate-severe traumatic brain injury.

J Clin Exp Neuropsychol 2022 Jul 25:1-16. Epub 2022 Jul 25.

Department of Hearing and Speech Sciences, Vanderbilt University Medical Center, Nashville, TN, USA.

Introduction: Temporal order memory is a core cognitive function that underlies much of our behavior. The ability to bind together information within and across events, and to reconstruct that sequence of information, critically relies upon the hippocampal relational memory system. Recent work has suggested traumatic brain injury (TBI) may particularly impact hippocampally mediated relational memory. Read More

Memory-augmented skip-connected autoencoder for unsupervised anomaly detection of rocket engines with multi-source fusion.

ISA Trans 2022 Jul 14. Epub 2022 Jul 14.

Science and Technology on Liquid Rocket Engine Laboratory, Xi'an Aerospace Propulsion Institute, Xi'an 710100, PR China.

To ensure the safety and stability of the rocket, it is essential to implement accurate anomaly detection on key parts such as the liquid rocket engine (LRE). However, due to the indistinct features of signals under the interference of extreme conditions and the weak distinguishing ability to exist unsupervised methods, it is difficult to distinguish abnormal samples from normal samples, which leads to the failure of reliable anomaly detection. Aiming at this problem, this paper proposed an unsupervised learning algorithm named Memory-augmented skip-connected deep autoencoder (Mem-SkipAE) for anomaly detection of rocket engines with multi-source data fusion.

The hippocampal formation as a hierarchical generative model supporting generative replay and continual learning.

Prog Neurobiol 2022 Jul 21;217:102329. Epub 2022 Jul 21.

Institute of Cognitive Sciences and Technologies, National Research Council, Rome, Italy. Electronic address:

We advance a novel computational theory of the hippocampal formation as a hierarchical generative model that organizes sequential experiences, such as rodent trajectories during spatial navigation, into coherent spatiotemporal contexts. We propose that the hippocampal generative model is endowed with inductive biases to identify individual items of experience (first hierarchical layer), organize them into sequences (second layer) and cluster them into maps (third layer). This theory entails a novel characterization of hippocampal reactivations as generative replay: the offline resampling of fictive sequences from the generative model, which supports the continual learning of multiple sequential experiences.

Department of Psychology, Temple University, 1701 N 13th Street, Philadelphia, PA, 19122, USA.

Agency has been shown to facilitate episodic memory. However, most paradigms use simple list-learning tasks, which preclude the ability to characterize more associative forms of memory, such as binding of items into spatial and temporal context. Across two studies, we characterize the role of agency on associative memory formation. Read More

Institute of Psychology, Jagiellonian University, Krakow, Poland.

The growing interdisciplinary research field of psycholinguistics is in constant need of new and up-to-date tools which will allow researchers to answer complex questions, but also expand on languages other than English, which dominates the field. One type of such tools are picture datasets which provide naming norms for everyday objects. However, existing databases tend to be small in terms of the number of items they include, and have also been normed in a limited number of languages, despite the recent boom in multilingualism research.
