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.

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.

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.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.

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.

Prevailing theories link prefrontal cortex (PFC) maturation to the development of declarative memory. However, the precise spatiotemporal correlates of memory formation in the developing brain are not known. We provide rare intracranial evidence that the spatiotemporal propagation of frontal activity supports memory formation in children. Seventeen subjects (6.2 to 19.4 years) studied visual scenes in preparation for a recognition memory test while undergoing direct cortical monitoring. Earlier PFC activity predicted greater accuracy, and subsecond deviations in activity flow between subregions predicted memory formation. Activity flow between inferior and precentral sites was refined during adolescence, partially explaining gains in memory. In contrast, middle frontal activity predicted memory independent of age. These findings show with subsecond temporal precision that the developing PFC links scene perception and memory formation and underscore the role of the PFC in supporting memory development.

False recognition occurs when people mistakenly claim that a novel item is familiar. After studying lists of semantically related words, healthy controls show extraordinarily high levels of false recognition to nonstudied lures that are semantic associates of study list words. In previous experiments, we found that both Korsakoff and non-Korsakoff amnesic patients show reduced levels of false recognition to semantic associates, implying that the medial temporal/diencephalic structures that are damaged in amnesic patients are involved in the encoding and/or retrieval of information that underlies false recognition. These data contrast with earlier results indicating greater false recognition in Korsakoff amnesics than in control subjects. The present experiment tests the hypothesis that greater or lesser false recognition of semantic associates in amnesic patients, relative to normal controls, can be demonstrated by creating conditions that are more or less conducive to allowing true recognition to suppress false recognition. With repeated presentation and testing of lists of semantic associates, control subjects and both Korsakoff and non-Korsakoff amnesics showed increasing levels of true recognition across trials. However, control subjects exhibited decreasing levels of false recognition across trials, whereas Korsakoff amnesic patients showed increases across trials and non-Korsakoff amnesics showed a fluctuating pattern. Consideration of signal detection analyses and differences between the two types of amnesic patients provides insight into how mechanisms of veridical episodic memory can be used to suppress false recognition.
