The purpose of the present study was to investigate further the semantic processing impairments of less skilled comprehenders. It tested the hypothesis that this difficulty results from an alteration in the multimodal integration mechanism involved in knowledge emergence as described within multi-trace memory models. To test this assumption, Brunel...

Similar events may reduce the likelihood of the cognitive system to accurately remember a specific memory. Similarity leads to overlap between mnemonic traces, which, in turn, interferes with the discrimination of the traces. Therefore, it is important to determine how and when overlapping is detrimental to the discrimination between the traces. Ac...

It has been proposed that representations emerge from a single memory system organized along a continuum of specificity. This continuum is assumed to reflect a scale between the simulation of overlapping and specific features of the traces, which depends on trace distinctiveness. More specifically, higher trace distinctiveness facilitates the simul...

The aim of this work was to test the hypothesis that motor fluency should help the integration of the components of the trace and therefore its re-construction. In the encoding phase of each of the three experiments we conducted, a word to be remembered appeared colored in blue or purple. Participants had to read these words aloud and, at the same...

A regular rhythmic stimulation increases people’s ability to anticipate future events in time and to move their body in space. Temporal concepts are usually prescribed to spatial locations through a past-behind and future-ahead mapping. In this study, we tested the hypothesis that a regular rhythmic stimulation could promote the forward-body (i.e.,...

The constructive nature of memory implies a possible confusion between details of similar events. Memory interventions should thus target the reduction of memory errors. We postulate that a brief intervention called Episodic Specificity Induction (ESI) facilitates the sensorimotor simulation of event-related details by improving the distinctiveness...

The aim of the present study was to demonstrate the multisensory nature of vocabulary knowledge by using learning designed to encourage the simulation of sensorimotor experiences. Forty participants were instructed to learn pseudowords together with arbitrary definitions, either by mentally experiencing (sensorimotor simulation) the definitions, or...

We evaluate the effects of multisensory training on letters, including sonification of graphic symbols. We used “spatial sonification” where letter handwriting movements recorded in a two dimensional plan, vertical and horizontal, are systematically assigned to two acoustic features, spectral composition for the horizontal axis and frequency for th...

Would you get close to a stinky perfume bottle or to a loudspeaker producing noise? In this paper, we present two procedures that allowed us to assess the ability of auditory and olfactory cues to elicit automatic approach/avoidance reactions toward their sources. The procedures resulted from an adaptation of the Visual Approach/Avoidance by the Se...

Embodied and situated cognition predicts direct interactions between sensorimotor and cognitive processing. This perspective presents evidence of such interactions by focusing on sensory and memory processing in young adults and the mechanisms underpinning these interactions. These embodied and situated mechanisms bring up not only fundamental epis...

L’approche incarnée et située prédit des interactions directes entre les traitements sensorimoteurs et cognitifs. Cet article présente les arguments en faveur de telles interactions en se concentrant sur le fonctionnement sensoriel et mnésique chez le jeune adulte, ainsi que sur la question des mécanismes qui sous-tendent ces interactions. Ces méca...

The Cognitive Space-Time. The objective of this article is to introduce the approach of cognition defended in this special issue, that of embodied cognition, rooted in the interactions that the body maintains with the environment, emerging from these same interactions, and situated, because it originates in the present situation, thus allowing an a...

Présentation de deux paradigmes permettant respectivement de faciliter ou d'interférer avec la simulation sensorimotrice. Le paradigme de facilitation repose sur l'utilisation d'une Induction de Spécificité Épisodique (ISE, Madore, Gaesser & Schacter, 2014), tandis que le paradigme d'interférence repose sur l'utilisation d'un Masque Visuel Dynamiqu...

Introduction. – Several studies have shown that adults can memorize an audio-visual association inresponse to an incidental presentation. Moreover, a motor experience of the letter-shape promotes letterknowledge and reading acquisition. Objective. – In order to develop optimal learning designs for children, we evaluate the effect of the implicitlea...

This study investigates the links between memory and emotion and, more specifically, how emotions can impact the integration mechanism. The authors' hypotheses were based on a dynamic conception of memory (Versace et al., 2014; Macri et al., 2018), and stated that an emotion coming from the stimulus (within-item emotion) should enhance the integrat...

Le vieillissement affecte de nombreux domaines dont les sens, mais aussi, le cerveau et donc la cognition. Après avoir décrit ces atteintes sensorielles et cognitives concomitantes qui sont fréquemment rapportées dans le vieillissement, ce travail présentera les différentes hypothèses explicatives. Nous proposerons alors une interprétation selon le...

Memories are not frozen in the past. Instead, they can be dynamically combined to allow individuals to adapt to the present or even imagine the future. This recombination, called event construction, also means that it might be possible to improve memory through specific interventions such as episodic specificity induction (ESI). ESI provides brief...

L’Induction de Spécificité Épisodique (ISE) est un court entraînement à la récupération des détails d’une expérience permettant d’augmenter la production de détails épisodiques (internes) lors de la description subséquente d’un nouvel événement. L’ISE s’est avérée efficace pour différentes populations, dont les personnes âgées, et dans de nombreuse...

To prevent forgetting in working memory, the attentional refreshing is supposed to increase the level of activation of memory traces by focusing attention. However, the involvement of memory traces reactivation in refreshing relies in the majority on indirect evidence. The aim of this study was to show that refreshing relies on the reactivation of...

Based on claims resulting from grounded cognition theory that perceptual and memory processes are using the same distributed systems, the present study investigated the temporal aspect of access to memory traces through haptic and auditory modalities. Unlike in the case of visual or auditory components, the perception of a vibrotactile component is...

Cette étude s’intéresse au lien entre mémoire et émotion et plus spécifiquement à la façon dont l’émotion peut influencer le mécanisme d’intégration. Les hypothèses des auteurs ont pour support une conception dynamique de la mémoire (Versace et al., 2014; Macri et al., 2017) et postulent qu’une émotion provenant d’un stimulus (émotion intra-item) d...

Based on claims resulting from grounded cognition theory that perceptual and memory processes are using the same distributed systems, the present study investigated the temporal aspect of access to memory traces through haptic and auditory modalities. Unlike in the case of visual or auditory components, the perception of a vibrotactile component is...

This study investigates the effects of emotion on the integration mechanism which binds together the components of an event and the relations between these components and encodes them within a memory trace [Versace, R., Vallet, G. T., Riou, B., Lesourd, M., Labeye, É, & Brunel, L. (2014). Act-In: An integrated view of memory mechanisms. Journal of...

Embodiment has highlighted the importance of sensory-motor components in cognition. Perception and memory are thus very tightly bound together, and episodic and semantic memories should rely on the same grounded memory traces. Reduced perception should then directly reduce the ability to encode and retrieve an episodic memory, as in normal aging. M...

Numerous studies have explored the effect of sleep on memory. It is well known that a period of sleep, compared to a similar period of wakefulness, protects memories from interference, improves performance, and might also reorganize memory traces in a way that encourages creativity and rule extraction. It is assumed that these benefits come from th...

Oral presentation at the 58th Annual Conference of the French Society of Psychology

People simulate themselves moving when they view a picture, read a sentence, or simulate a situation that involves motion. The simulation of motion has often been studied in conceptual tasks such as language comprehension. However, most of these studies investigated the direct influence of motion simulation on tasks inducing motion. This article in...

Oral presentation at the Journée d’étude du Viellissement Cognitif, Bordeaux (France)

Based on claims resulting from grounded cognition theory that perceptual and memory processes are using the same distributed systems, the present study investigated the temporal aspect of access to memory traces through haptic and auditory modalities. Unlike in the case of visual or auditory components, the perception of a vibrotactile component is...

How do we represent the meaning of words? The present study assesses whether access to conceptual knowledge requires the re-enactment of the sensory components of a concept. The re-enactment, i.e. simulation, was tested in a word categorization task using an innovative masking paradigm. We hypothesized that a meaningless reactivated visual mask sho...

Poster presentation at the 6th International Conference on Memory

The aims of the present studies are to assess the sensory nature hypothesis of knowledge through a series of experimental results. Especially, we investigated the links between memory and perception using a short-term priming paradigm based on a previous learning phase consisting of the association between a geometrical shape and a white noise. Con...

The relationship between perceptual and memory processing is at the core of cognition. Growing evidence suggests reciprocal influences between them so that memory features should lead to an actual perceptual bias. In the present study, we investigate the reciprocal influence of perceptual and memory processing by further adapting the Ebbinghaus ill...

Poster presentation at the 19th Conference of the European Society for Cognitive Psychology

Poster presentation at the 56th Conference of the French Society of Psychology

There is much behavioral and neurophysiological evidence in support of the idea that seeing a tool activates motor components of action related to the perceived object (e.g., grasping, use manipulation). However, the question remains as to whether the processing of the motor components associated with the tool is automatic or depends on the situati...

According to grounded theories of cognition, knowledge is grounded in its sensory-motor features. Therefore, perceptual and conceptual processing should be based on the same distributed system so that conceptual and perceptual processes should interact. The present study assesses whether gustatory stimulation (participants tasted a sweet or a nonsw...

Un phénomène particulièrement avéré en mémoire est l’observation même que si un élément spécifique semble être différent ou rare d’une certaine manière des autres éléments présents dans le même contexte d’encodage, cet élément est susceptible d’être mieux rappelé. Ce phénomène, appelé l’effet von Restorff ou l’effet d’isolation, est connu depuis 19...

Does a visual mask need to be perceptually present to disrupt processing? The present re- search proposed to explore the link between perceptual and memory mechanisms by demonstrating that a typical sensory phenomenon (visual masking) can be replicated at a memory level. Experiment 1 highlighted an interference effect of a visual mask on the catego...

The aim of this study was to show that sensory-motor consequences of past actions form part of memory trace components cued by current experience. In a first task participants had to learn a list of words. Then in a guessing task they played against the computer. Finally, in a recognition task, they had to judge if the words were or were not presen...

Grounded cognition theories state that conceptual knowledge is closely linked to the current situation and embodied in sensory dimensions. Alongside the interaction with the environment, knowledge related to our environment is continually recovered from memory. Thus, the perceptual situation is closely linked to the reactivated traces in memory. Vi...

Based on recent behavioral and neuroimaging data suggesting that memory and perception are partially based on the same sensorimotor system, the theoretical aim of the present study was to show that it is difficult to dissociate memory mechanisms from perceptual mechanisms other than on the basis of the presence (perceptual processing) or absence (m...

The present article proposes a new memory model called Act-In (Activation-Integration). Act-In extends the multiple trace memory models by placing them within the situated cognition perspective. Act-In considers that the activation and integration mechanisms play a key role in memory processes. These mechanisms are involved in both the construction...

Based on recent behavioral and neuroimaging data suggesting that memory and perception are partially based on the same sensorimotor system, the theoretical aim of the present study was to show that it is difficult to dissociate memory mechanisms from perceptual mechanisms other than on the basis of the presence (perceptual processing) or absence (m...

Et si Descartes s’était trompé en affirmant que nous prenons nos décisions sur la base de notre seule raison ? Et si nos émotions, ingrédient des souvenirs, nous aidaient dans nos choix ?

When they live through an experience, individuals both perceive sensorimotor components in the environment (perception) and reactivate properties associated with the experience that are not perceptually present (memory). According to embodiment theory, memory consists of sensorimotor traces that are reactivated during the experience. The aim of thi...

Slow wave sleep (SWS) is known to favour episodic memory consolidation. Given that ageing is associated with a reduction in SWS and episodic memory impairment, our aim was to investigate whether memory continues to benefit from sleep in older adults. Episodic memory consolidation was tested in 20 young (22.1 ± 1.7 years) and 20 older volunteers (68...

Many studies have reported that emotion could affect our hedonic evaluation of food. In order to investigate the origin of this effect, we have conducted an experiment in which the consequences of emotional memory priming on gustative evaluation have been assessed. In the Act-In model (Activation-Integration, Versace et al., 2009), memory traces ar...

Introduction. Memory errors might distinguish clinical populations such as Alzheimer's Disease (AD) and Semantic Dementia (SD). However, very little neuropsychological tests consider memory errors in their norms and scores. The present study proposes a new memory test created to assess simultaneously episodic and semantic memory and to differentiat...

The objective of the present study was to provide a better understanding of the factors that influence discrimination and subjective assessment of vibrotactile feedbacks during active interaction with a touchscreen. Twenty-four participants were presented with 162 pairs of vibrotactile signals that varied in frequency (60 Hz, 130 Hz, 200 Hz), wavef...

The goal of the present study was to find evidence for a multisensory generalization effect (i.e., generalization from one sensory modality to another sensory modality). The authors used an innovative paradigm (adapted from Brunel, Labeye, Lesourd, & Versace, 2009 ) involving three phases: a learning phase, consisting in the categorization of geome...

Priming paradigms exist under different forms such as repetition priming or semantic priming. While numerous studies have focused on repetition priming, fewer studies were realized on cross-modal priming effects (e.g., Schneider, Engel, & Debener, 2008). The cross-modal priming effect is generally supposed to be semantic (e.g., Chen & Spence, 2010)...

The nature of knowledge and its relationship with the perceptual processes are among the most central issues in the study of human cognition. Should knowledge be abstract, then semantic memory and perception should be relatively independent. On the contrary, if knowledge is sensory-dependent, then memory and perception should be very close. The fir...

The nature of audio-visual interactions is poorly understood for meaningful objects. These interactions would be indirect through semantic memory according to the amodal nature of knowledge, whereas these interactions would be direct accord-ing to the modal nature of knowledge. This question, cen-tral for both memory and multisensory frameworks, wa...

The nature of knowledge, i.e. sensory-dependent or abstract, is controversial. Growing evidence supports the existence of sensory-dependent knowledge in young individuals, but this question remains unexplored in elderly individuals. Thus the first objective of this study was to assess sensory-dependent knowledge in normal aging using a cross-modal...

This study examined the relationship between memory and perception in order to identify the influence of a memory dimension in perceptual processing. Our aim was to determine whether the variation of typical size between items (i.e., the size in real life) affects visual search. In two experiments, the congruency between typical size difference and...

The aim of this article was to provide experimental evidence that classical dissociation between levels of consciousness associated with memory retrieval (i.e., implicit or explicit) can be explained in terms of task dependency and distinctiveness of traces. In our study phase, we manipulated the level of isolation (partial vs. global) of the memor...

The main objective of our study was to confirm that the distinctiveness effect could emerge in implicit memory tasks and to show that the specificity of an item can be varied by manipulating the contextual information associated with the item during encoding. In an encoding phase and test phase, participants had to categorize target words as referr...

The aim of this study was to demonstrate that the cross-modal priming effect is perceptual and therefore consistent with the idea that knowledge is modality dependent. We used a two-way cross-modal priming paradigm in two experiments. These experiments were constructed on the basis of a two-phase priming paradigm. In the study phase of Experiment 1...

The aim of the present study was to show that the probability of an item being retrieved is proportional to its spatial distinctiveness, and that this distinctiveness effect can be obtained in an implicit memory task. The participants were presented with two phases in which they had to categorise pictures of objects as either ‘‘kitchen utensils’’ o...

The aim of the present study was to show the perceptual nature of conceptual knowledge by using a priming paradigm that excluded an interpretation exclusively in terms of amodal representation. This paradigm was divided into two phases. The first phase consisted in learning a systematic association between a geometrical shape and a white noise. The...

The aim of this study was to provide evidence that memory and perceptual processing are underpinned by the same mechanisms. Specifically, the authors conducted 3 experiments that emphasized the sensory aspect of memory traces. They examined their predictions with a short-term priming paradigm based on 2 distinct phases: a learning phase consisting...

Through a review of the literature, this paper proposes arguments in favour of a multimodal, dynamic, functional and situational conception of memory. Memory is assumed to contain traces which reflect past experiences. The properties of these experiences are considered to be distributed across multiple neuronal systems which are responsible, in par...
