France

The Laboratoire  de Psychologie Cognitive (LPC, UMR 7290) is one of the biggest CNRS research units in cognitive and experimental psychology in France. It is located on the St. Charles campus of Aix-Marseille University in an interdisciplinary centre on Cognition, Brain and Behavior (Féderation de Recherche 3C).  The LPC is one of the founding members of the centre of excellence on Brain & Language (LABEX BLRI) and the Institute of Conergence on Language Brain and Communication..

Research conducted at the LPC aims to further our understanding of the fundamental mechanisms underlying cognitive functions (perception, memory, reasoning, language, categorization, vision). Much of the research conducted at the LPC tackles major societal challenges, such as cognitive decline associated with aging, language and learning disorders (dyslexia), education, public health, consumer behavior or the effects of stereotypes on cognition. The LPC is at the origin of various applied project that go from the development of early diagnosis of learning disorders to evidence-based computerized intervention methods or smartphone applications for cognitive science.

Research teams

The research is structured around five main themes, each represented by a team:

  • Cognition and social neurosciences
  • Perception and attention
  • Developpment and cognitive aging
  • Language
  • Comparative cognition

All LPC teams are affiliated to the neuroscience master’s program and can thus train neuroscience master’s students and offer them projects to apply for a Ph.D. scholarship.

Cognition and social neurosciences (Isabelle Régner)

Created in 2005 under the joint impulse of P. Huguet and J.-P. Caverni, this multidisciplinary team has supported its development on the former “Inference” team, of which it is an extension. While allowing the continuation of the work on inferences and reasoning, the new team allows to deepen the study of socially regulated cognition. Despite the institutional and / or editorial responsibilities of most of its members, since 2006 the team has published 87 articles in mostly international mediums from good to excellent (see below).

Mental activities and their underlying neurobiological processes are anchored in social contexts and functions whose influence is now the subject of much work at the international level in reference to “social cognition” and “social and affective neuroscience” . It is precisely the main characteristic of the Cognition and Social Context team that it integrates this social dimension of cognition. Our approach assumes that mental activities, while expressing the most integrated form of biological life, also depend on the social contexts offered or imposed on individuals when processing information. This interest of the team for the social regulation of cognitive functioning is original because of its complementarity with the North American current of social cognition. In this framework, the integration of the information processing mechanisms described by cognitive psychology aims mainly at understanding how the individual organizes his / her social environment mentally. In Team 1 of the LPC, it is more the influence of this environment on the cognitive processes themselves that is the subject of the investigations.

Our laboratory and natural site work contributes to the elucidation of how certain basic elements of life in society (eg, presence of others, self – assessments, social comparisons, social stereotypes) Information in the areas of reasoning, memory and attention. In addition to their interest in the study of human cognition in its social dimension, this work provides a pathway to improve learning and training environments at all ages of life. The approach is resolutely highly integrated, hence the presence in the team of social psychology specialists of cognition, cognitive psychology, behavioral genetics and neuroscience, and the use of methods in these different sectors .

Human cognition and behavior

Perception and attention (Eric Castet, Françoise Vitu)

Our research focuses on the study of perceptual, attentional and oculomotor processes involved in everyday tasks such as reading, the processing of natural visual scenes and the recognition of familiar shapes (letters, words, objects and handwriting). It investigates

  1. the mechanisms involved in the programming of saccadic eye movements,
  2. the orientation of visual attention and its relationship with eye movements and pupil constriction/dilation,
  3. intra-saccadic visual perception and the integration of information across saccades,
  4. attention and visual short term memory,
  5. the visual constraints that affect letter perception (e.g., crowding),
  6. the nature and role of orthographic processing in word recognition,
  7. the role of attention in the processing of adjacent words,
  8. the modeling of shape, letter and word recognition,
  9. the study and modeling of eye movements during reading, with an emphasis on oculomotor mechanisms and perceptual processes, as well as their interactions with language-related processes,
  10. oculomotor control, visual perception and reading with a central scotoma,
  11. the influence of visual salience and object-identification processes on eye guidance during the perception of natural scenes.

Our work relies on a wide variety of methodologies and techniques classically used in experimental psychology, psychophysics and behavioral and computational neuroscience. These include the measurement of detection and discrimination thresholds, reaction times, perceptual identification performance, event-related potentials, eye movements, functional imaging and modelling. Part of our research is conducted on low-vision patients, and in particular patients with Age-related Macular Degeneration (AMD).

Cognitive development and aging (Agnès Blaye)

Our research aims at understanding the mechanisms involved in high-level cognitive activities (memory, executive control, reasoning, problem solving) and how these mechanisms change during cognitive development and aging.

In particular, we address questions fundamental for both cognitive psychology and the psychology of cognitive development and aging, such as:

  • How do the characteristics of the task, stimuli and participants influence cognitive performance?
  • Do these effects change during development and aging?
  • What are the determinants and mechanisms underlying cognitive development and aging?

During our experiments, we collect various measurements of cognitive activity: verbal reports, video recordings, response time and precision, eye movements, fMRI, ERP and MEG.

Comparative cognition (Joël Fagot)

Composed of psychologists specialized in animal or human cognition, our team focuses on cognitive architecture by analyzing the complementary processes of perception, attention, memory, learning and reasoning, social cognition and language. Its particularity is to study these phenomena by comparing human cognition to that of two other species, baboon monkeys and dogs. Through this comparison, we seek to better define the cognitive processes unique to humans, possibly subject to linguistic influences, and those more widely shared in the phylogeny. Our research on monkeys is performed on a unique platform where animals kept in social groups have free access to experimental stations.
