The aim of this study was to assess the influence of melodic and rhythmic redundancies, and their interaction with tonality, on recognition memory for music. Forty-four non-musicians performed a recognition task with unknown musical material. Stimuli created for experimental purposes were made up of 48 short melodies (half tonal and half non-tonal) and were characterized by the presence of three kinds of musical redundancy: melodic only, rhythmic only, or both melodicrhythmic. In a first phase, subjects listened to a study list of 24 stimuli. After 20 minutes, a test list containing 48 stimuli (24 previously heard and 24 novel ones) was administered, and subjects were asked to indicate for each item whether the melody: was recognized from the study list (R response); evoked a sense of familiarity (K response); or was not recognized at all (X response). Major results showed that tonality influences semantic, but not episodic memory, and that the two systems are differentially affected by the type of redundancy (especially melodic-rhythmic, which has a large effect on episodic memory but is ineffective for semantic memory). Moreover, tonality and the type of redundancy systematically interact only in the episodic memory system. Thus, evidence supports disassociation of the two memory systems. Furthermore, R and X responses showed a symmetry in their trend, suggesting a role for X responses as counterparts of the R responses within the episodic memory system. Melodic-rhythmic redundancy demonstrated the most prominent effects on the episodic system, whereas the assessment comparing melodic versus rhythmic only as the pre-eminent type of redundancy was more ambiguous. Finally, non-tonal stimuli were found to be more sensitive than tonal stimuli, whereby they showed differential effectiveness regarding redundancy type, a result which suggests that they could prove serviceable in future studies concerning recognition memory for music.

Attention Hypothesis

Retrieval results in both costs and benefits to episodic memory. Output interference (OI) refers to the finding that episodic memory accuracy decreases with increasing test trials. Release from OI is the restoration of original accuracy at some point during the test. For example, a release from OI in recognition memory testing occurs when the semantic similarity between stimuli decreases midway through testing, suggesting that item representations stored on early trials cause interference on tests occurring on later trials to the extent that the earlier items share features with the latter items. In two recognition memory experiments, we demonstrate release from OI for words and faces. We also test whether release from OI is the result of interference or is due to a boost in attention caused by reorienting to a novel stimulus type. A test for the foils presented during the initial test list supports the interference account of OI. Implications for models of memory are discussed.

Matching Models

Models of episodic memory propose that recognition memory operates via a process of global matching. Mewhort and Johns (2000) directly tested this retrieval mechanism by manipulating the feature composition of studied items and test probes using combinations of various colors and shapes. They found that rejection of unstudied probes was greatly facilitated when the probe contained features not on the study list even when the other features were of the probe were strongly represented on the list, an advantage dubbed the extralist feature effect. In this work, we explore the boundary conditions of the extralist feature effect by constructing experiments with continuous dimension stimuli using bothintegral (Experiment 1) and separable-dimension (Experiment 2) stimuli. An extralist feature effect was only found in Experiment 2. Experiment 1’s results were well described by the exemplar-based linear ballistic accumulator (EB-LBA) model, but the model was unable to explain the results in Experiment 2. We explored EB-LBA variants that allowed for decision making to be based on feature dimensions rather than the entire stimulus – these variants predicted extralist feature advantages but performed poorly otherwise. We additionally explored models that allowed for extra attention to be devoted to the dimension that contains the extralist feature. While these models performed best, it is unclear how attention could be directed in this fashion.

Mammalian Brain

The dual system hypothesis posits the existence of two neural systems for memory and learning in the mammalian brain: the habit system and the improvisational system. This study sought to determine whether both systems are involved in a visual recognition task originally outlined in Sternberg (1966) and whether each system could be selectively engaged on the basis of response assignment. Seventeen undergraduate students participated in an immediate visual recognition task where they responded whether or not a test consonant was present in a previous study sequence of one to six consonants by pressing one key for same or another key for different. When the different response was assigned to the spatially right “J” key, reaction time for targets and lures was a function of the study sequence size, indicating that the study sequence was serially scanned and compared with the test item by the habit system. However, when the same response was assigned to the spatially right “J” key, reaction time was not a function of study sequence size, indicating that the test item was not compared with the study sequence and responses were instead determined by perceived recency/novelty of the test item by the improvisational system. Differences in reaction time depending on response assignment suggest the selection of one memory system over the other based on verbal labels assigned to response keys in different spatial locations. Verbal label refers to the label of same or different assigned to the response keys in the experiment instructions. Results expand upon Sternberg (1966)—which used the same visual recognition task design as this study but did not account for response assignment, obscuring evidence of contributions from both memory systems—and provide more evidence for the dual-system hypothesis by demonstrating the involvement of both memory systems in immediate visual recognition.

Different Sources

Episodic memory involves remembering not only what happened but also where and when the event happened. This multi-component nature introduces different sources of interference which stem from previous experience. However, it is unclear how different interferences change across development and what may cause the changes. To address these questions, we tested 4-5-year-olds (N = 103), 7-8-year-olds (N = 82), and adults (N = 70) using item and source recognition memory tasks with various manipulations (i.e., list-length, list-strength, and word-frequency), and decomposed sources of interference using a computational model. We find that interference stemming from other items on the study-list rapidly decreases with development, whereas interference from pre-experimental contexts gradually decreases but remains the major source of interference. The model further quantifies these changes indicating that the ability to discriminate items undergoes relatively rapid development, whereas the ability to discriminate contexts undergo protracted development. These results elucidate fundamental aspects of memory development.

Aggleton & Brown (A&B) propose that the hippocampal-anterior thalamic and perirhinal-medial dorsal thalamic systems play independent roles in episodic memory, with the hippocampus supporting recollection-based memory and the perirhinal cortex, recognition memory. In this commentary we discuss whether there is experimental support for the A&B model from studies of long-term memory in semantic dementia.

Abstract. Four experiments were conducted investigating the effect of size congruency on facial recognition memory, measured by remember, know and guess responses. Different study times were employed, that is extremely short (300 and 700 ms), short (1,000 ms), and long times (5,000 ms). With the short study time (1,000 ms) size congruency occurred in knowing. With the long study time the effect of size congruency occurred in remembering. These results support the distinctiveness/fluency account of remembering and knowing as well as the memory systems account, since the size congruency effect that occurred in knowing under conditions that facilitated perceptual fluency also occurred independently in remembering under conditions that facilitated elaborative encoding. They do not support the idea that remember and know responses reflect differences in trace strength.

Efficient Memory

In this study, a simple and effective memory system required for the implementation of an AI chip is proposed. To implement an AI chip, the use of internal or external memory is an essential factor, because the reading and writing of data in memory occurs a lot. Those memory systems that are currently used are large in design size and complex to implement in order to handle a high speed and a wide bandwidth. Therefore, depending on the AI application, there are cases where the circuit size of the memory system is larger than that of the AI core. In this study, SDRAM, which has a lower performance than the currently used memory system but does not have a problem in operating AI, was used and all circuits were implemented digitally for simple and efficient implementation. In particular, a delay controller was designed to reduce the error due to data skew inside the memory bus to ensure stability in reading and writing data. First of all, it verified the memory system based on the You Only Look Once (YOLO) algorithm in FPGA to confirm that the memory system proposed in AI works efficiently. Based on the proven memory system, we implemented a chip using Samsung Electronics’ 65 nm process and tested it. As a result, we designed a simple and efficient memory system for AI chip implementation and verified it with hardware.

AbstractListening to autobiographically-salient music (i.e., music evoking personal memories from the past), and transcranial direct current stimulation (tDCS) have each been suggested to temporarily improve older adults’ subsequent performance on memory tasks. Limited research has investigated the effects of combining both tDCS and music listening together on cognition. The present study examined whether anodal tDCS stimulation over the left dorsolateral prefrontal cortex (2 mA, 20 min) with concurrent listening to autobiographically-salient music amplified subsequent changes in working memory and recognition memory in older adults than either tDCS or music listening alone. In a randomized sham-controlled crossover study, 14 healthy older adults (64–81 years) participated in three neurostimulation conditions: tDCS with music listening (tDCS + Music), tDCS in silence (tDCS-only), or sham-tDCS with music listening (Sham + Music), each separated by at least a week. Working memory was assessed pre- and post-stimulation using a digit span task, and recognition memory was assessed post-stimulation using an auditory word recognition task (WRT) during which electroencephalography (EEG) was recorded. Performance on the backwards digit span showed improvement in tDCS + Music, but not in tDCS-only or Sham + Music conditions. Although no differences in behavioural performance were observed in the auditory WRT, changes in neural correlates underlying recognition memory were observed following tDCS + Music compared to Sham + Music. Findings suggest listening to autobiographically-salient music may amplify the effects of tDCS for working memory, and highlight the potential utility of neurostimulation combined with personalized music to improve cognitive performance in the aging population.

AbstractThe episodic memory system allows us to experience the emotions of past, counterfactual, and prospective events. We outline how this phenomenological experience can convey motivational incentives for farsighted decisions. In this way, we challenge important arguments for Mahr & Csibra's (M&C's) conclusion that future-oriented mental time travel is unlikely to be a central function of episodic memory.

Research on pupillometry provides an increasing evidence for associations between pupil activity and memory processing. The most consistent finding is related to an increase in pupil size for old items compared with novel items, suggesting that pupil activity is associated with the strength of memory signal. However, the time course of these changes is not completely known, specifically, when items are presented in a running recognition task maximizing interference by requiring the recognition of the most recent items from a sequence of old/new items. The sample comprised 42 healthy participants who performed a visual word recognition task under varying conditions of retention interval. Recognition responses were evaluated using behavioral variables for discrimination accuracy, reaction time, and confidence in recognition decisions. Pupil activity was recorded continuously during the entire experiment. The results suggest a decrease in recognition performance with increasing study-test retention interval. Pupil size decreased across retention intervals, while pupil old/new effects were found only for words recognized at the shortest retention interval. Pupillary responses consisted of a pronounced early pupil constriction at retrieval under longer study-test lags corresponding to weaker memory signals. However, the pupil size was also sensitive to the subjective feeling of familiarity as shown by pupil dilation to false alarms (new items judged as old). These results suggest that the pupil size is related not only to the strength of memory signal but also to subjective familiarity decisions in a continuous recognition memory paradigm.
