While previous studies have shown the importance of visuo-spatial working memory in the processing of co-speech iconic gestures, clear evidence for a potential involvement of the verbal working memory (vWM) is currently lacking. To address this issue, participants in the present study were presented with a dual task paradigm. The main outcome varia...

Embodied approach postulates that knowledge and conceptual representations are grounded in action and perception. In order to investigate the involvement of sensorimotor information in conceptual and cognitive processing, researchers have collected various norms in young adults. For instance, the perceptual strength (PS) assesses perceptual experie...

Numerous studies have explored the benefit of iconic gestures in speech comprehension. However, only few studies have investigated how visual attention was allocated to these gestures in the context of clear versus degraded speech and the way information is extracted for enhancing comprehension. This study aimed to explore the effect of iconic gest...

This narrative review aimed to explore the existing knowledge in order to examine the multiple forms of late-life depression (LLD) within a non-neurodegenerative or a neuro-degenerative context, in particular Alzheimer's disease (AD). This review will first provide information about different pathogenic hypotheses proposed to describe LLD when it i...

Perceptual experience through the five modalities (i.e., vision, hearing, touch, taste, and smell) has demonstrated its key role in semantics. Researchers also highlighted the role of interoceptive information in the grounded representation of concepts. However, to this day, there is no available data across these modalities in the French language....

Objective : Late-life depression (LLD), mild cognitive impairment (MCI) and early stage of Alzheimer's disease (AD) can share a similar pattern of cognitive impairment, even if they don’t share the same functional causes. However, this overlap of cognitive profile, which is challenging for differential diagnosis between these pathologies, is not ex...

Iconic gesture-speech integration is a relatively recent field of investigation with numerous researchers studying its various aspects. The results obtained are just as diverse. The definition of iconic gestures is often overlooked in the interpretations of results. Furthermore, while most behavioral studies have demonstrated an advantage of bimoda...

ABSTRACT : Les mots homonymes (e.g. REFLEXION) sont polarisés, c’est-à-dire qu’ils comportent une acception dominante (e.g. PENSEE) et une acception subordonnée (e.g. REFLET). Ils constituent un matériel expérimental utilisé notamment dans des protocoles d’amorçage lors de l’investigation de la mémoire sémantique. Afin d’explorer les processus séma...

Cognitive profiles of early stage of Alzheimer's disease (AD) and Late-Life depression (LLD) show a clinical overlap, including in the memory domain. Nevertheless, the typical and ordered alteration of the semantic memory (SM) content in AD could be a distinctive element compared to in LLD where it would remain intact. A systematic review was condu...

Iconic gestures represent a form of non verbal communication intended to convey meaning during conversation. This meaning is linked to the verbal speech it accompanies suggesting a simultaneuous online processing of the spoken words and gestures. Given the online nature of the processing, it is plausible to expect the involvement of the verbal work...

Objectives: Although the influence of prior knowledge on associative memory in healthy aging has received great attention, it has never been studied in Alzheimer's disease (AD). This study aimed at assessing whether AD patients could benefit from prior knowledge in associative memory and whether such benefit would be related to the integrity of th...

Manipulable man-made objects are characterized by semantic features of different formats. While it is clear that functional declarative knowledge related to objects (i.e. what is an object for) belongs to semantic knowledge stored in memory, the nature of knowledge associated with object gesture of use (i.e. manipulation) remains unclear. We assume...
Article
The breakdown of semantic memory appears early in Alzheimer's disease (AD). Lexico-semantic difficulties (e.g. difficulties in retrieving words and their meaning) are among the first symptoms of the disease. In order to screen this lexico-semantic decline, we propose the mini-SKQ, a semantic knowledge questionnaire. Mini-SKQ explores semantic impai...

Les gestes constituent une part importante de la communication non verbale. Parmi eux, les gestes iconiques véhiculent une information sémantiquement et formellement liée au message verbal émis.

Verbal and nonverbal communication impairments are often observed in the context of neurodegenerative diseases. Identifying the most appropriate communication strategies for each patient, by a better understanding of his communicational difficulties, would help to maintain his autonomy and to improve his quality of life. Objective: To propose a r...

Nonverbal communication skills have been a growing subject of research. A main component of these skills consists of gesturing. Because they convey semantic information related to the verbal utterance, iconic gestures are particularly interesting to investigate. Studies showed that the iconic gesture/speech integration improved following congruent...

Article
Taxonomic and thematic relationships are core elements of lexico-semantic networks. However, the weight of both links differs in semantic memory, with distinct support for natural and manufactured objects: natural objects tend to be more taxonomically identified while manufactured objects benefit more from the underlying thematic relationships. Alz...

Objective: Semantic memory is the result of progressive development during childhood. During the construction of the lexico-semantic network, the features of the objects are progressively stored to build our knowledge. Alzheimer's disease (AD) disrupts conceptual links that support semantic memory. Individuals suffering from AD lose access to word...

If the semantic memory organization in adults is today relatively well-documented, the semantic knowledge development in childhood is still a matter of debate. This paper aims to describe the adjustment of the semantic knowledge questionnaire of Laiacona, Barbarotto, Trivelli and Capitani (1993) for adults in a children population. The adjusted ver...

Lexico-semantic difficulties are common in Alzheimer's disease (AD). The bottom-up process theory is today well accepted: superordinate attributes tend to decline slower than subordinate ones. However, a specific issue in semantic memory investigation in AD is to determine the severity of the semantic impairment. Given that the regularity of the se...

The aim of this study was to generalize the positive impact of auditory-visual bimodality on lexical retrieval in Alzheimer's disease (AD) patients. In practice, the naming skills of healthy elderly persons improve when additional sensory signals are included. The hypothesis of this study was that the same influence would be observable in AD patien...

Late life depression (LLD) and early stage of Alzheimer’s disease (AD) are two pathological conditions that share many similarities and are frequently comorbid. Both conditions can have clinical patterns that include mood and cognitive impairments, particularly in memory and executive functioning, making the differential diagnosis hard to achieve. The fact that each situation will require specific care in terms of medication, therapeutic management and cognitive treatment make early differential diagnosis essential. Furthermore, several authors propose the hypothesis of two forms of relationship between LLD and AD, depending on the onset of the first episode of depression. They suggest that late-onset LLD is more likely to be a prodromal sign of AD, as opposed to depression that has begun earlier during life and can be a risk factor for the disease. To improve the diagnosis, we propose that semantic impairment is a key factor in differentiating cognitive disorders between LLD and AD.
