“…At study, there were significant effects of stimulus repetition in the same task condition: RTs decreased rapidly between the first and second presentation and more slowly afterwards (following a quadratic distribution), as commonly found in semantic categorization tasks using multiple stimulus presentations (e.g., Renoult et al, 2012). In the different task condition, even though the same stimuli were also presented four times, the processing of these stimuli in different contexts appears to have cancelled the facilitatory effects of repetition, consistent with findings from previous studies reporting an absence of repetition priming when words are classified on different tasks (Ratcliff, Hockley, & McKoon, 1985;Vriezen & Moscovitch, 1990).…”

Repeated study typically improves episodic memory performance. Two different types of explanations of this phenomenon have been put forward: 1) reactivating the same representations strengthens and stabilizes memories, or 2) greater encoding variability benefits memory by promoting richer traces. The present experiment directly compared these predictions in a design with multiple repeated study episodes, allowing to dissociate memory for studied items and their context of study. Participants repeatedly encoded names of famous people four times, either in the same task, or in different tasks. During the test phase, an old/new judgement task was used to assess item memory, followed by a source memory judgement about the encoding task. Consistent with predictions from the encoding variability view, encoding stimulus in different contexts resulted in higher item memory. In contrast, consistent with the reactivation view, source memory performance was higher when participants encoded stimuli in the same task repeatedly. Taken together, our findings indicate that encoding variability benefits episodic memory, by increasing the number of items that are recalled. These benefits are however at the expenses of source recollection and memory for details, which are decreased, likely due to interference and generalisation across contexts.

Recent behavioural evidence suggests that when processing others' actions, motor acts and goalrelated information both contribute to action recognition. Yet the neuronal mechanisms underlying the dynamic integration of the two action dimensions remain unclear. this study aims to elucidate the eRp components underlying the processing and integration of grip and goal-related information. the electrophysiological activity of 28 adults was recorded during the processing of object-directed action photographs (e.g., writing with pencil) containing either grip violations (e.g. upright pencil grasped with atypical-grip), goal violations (e.g., upside-down pencil grasped with typical-grip), both grip and goal violations (e.g., upside-down pencil grasped with atypical-grip), or no violations. participants judged whether actions were overall typical or not according to object typical use. Brain activity was sensitive to the congruency between grip and goal information on the N400, reflecting the semantic integration between the two dimensions. On earlier components, brain activity was affected by grip and goal typicality independently. Critically, goal typicality but not grip typicality affected brain activity on the N300, supporting an earlier role of goal-related representations in action recognition. Findings provide new insights on the neural temporal dynamics of the integration of motor acts and goal-related information during the processing of others' actions.Understanding the actions performed by others is a core ability of human beings 1,2 . Yet, actions are no mere movements but organised and goal-directed movements 3,4 . Thus, understanding others' actions does not only imply the processing of the motor act (e.g., both dynamic and static components of reaching and grasping a bottle) but also the recognition of the actor's goal (e.g., to drink or to move it away). Accordingly, observers mainly perceive others' actions in terms of goals 5-8 and may use different sources of information to this end (e.g., dynamic and static component of the motor act 9 ; functional knowledge about objects 10 ; contextual information 11,12 , among others). Although numerous studies have demonstrated that both information about the motor act and information about the goal of the actor are processed during the decoding of others' actions, the precise role of the two types of information in action recognition remains debated.Important theoretical accounts have highlighted the need to consider the processing of others' actions as a dynamic phenomenon 3,13-15 that cannot be fully uncovered without considering the temporal dynamics of motor acts and action goal decoding. The observation of several successive periods of stability in the brain activity (i.e. "micro-state") when visually processing others' actions 16,17 further supports the idea that the decoding of others' actions is a multistep process. In a recent behavioural experiment, we also demonstrated that the involvement of action goal and static motor act information in action recog...

“…Modulations of the N400 have not always been reported in these studies of self-relevance, and when they were, self-relevance was sometimes associated with an increased (Muller & Kutas 1996) or a decreased amplitude (Ganis & Shendan, 2012). Note that some of these studies may have failed to identify N400 modulations as such because they used multiple presentations of the same stimuli (e.g., one's own name), which results in the N400 peaking substantially earlier than usual (e.g., Renoult & Debruille, 2011;Renoult, Wang, Calcagno, Prévost, & Debruille, 2012). Nonetheless, as self-relevant material could activate both personal semantics and episodic memory, modulations of both the N400 and the LPC would be expected.…”

Declarative memory is thought to consist of two independent systems: episodic and semantic.Episodic memory represents personal and contextually unique events, while semantic memory represents culturally-shared, acontextual factual knowledge. Personal semantics refers to aspects of declarative memory that appear to fall somewhere in between the extremes of episodic and semantic. Examples include autobiographical knowledge and memories of repeated personal events. These two aspects of personal semantics have been studied little and rarely compared to both semantic and episodic memory. We recorded the event-related potentials (ERPs) of 27 healthy participants while they verified the veracity of sentences probing four types of questions: general (i.e., semantic) facts, autobiographical facts, repeated events, and unique (i.e., episodic) 2 events. Behavioral results showed equivalent reaction times in all 4 conditions. True sentences were verified faster than false sentences, except for unique events for which no significant difference was observed. Electrophysiological results showed that the N400 (which is classically associated with retrieval from semantic memory) was maximal for general facts and the LPC (which is classically associated with retrieval from episodic memory) was maximal for unique events. For both ERP components, the two personal semantic conditions (i.e., autobiographical facts and repeated events) systematically differed from semantic memory. In addition, N400 amplitudes also differentiated autobiographical facts from unique events. Autobiographical facts and repeated events did not differ significantly from each other but their corresponding scalp distributions differed from those associated with general facts. Our results suggest that the neural correlates of personal semantics can be distinguished from those of semantic and episodic memory, and may provide clues as to how unique events are transformed to semantic memory.
