Cognitive Mechanism Study Research Group


Axe(s) of research

The cognitive mechanism study research group (EMC) has a rich and diversified research programme, aimed at several population types (children, young adults, the aged, cerebral lesion patients, psychiatric patients) extending to different subject areas (perception and attention, language, memory and emotion). Methods used include classical experimental psychology tools, neuropsychological dissociation in cerebral lesion patients, functional cerebral imagery and computerised stimulation. Educational activities are organised in close relationship with the group's research subjects. They cover all study cycles and consist of cognitive psychology training, cognitive sciences, cognitive neuroscience, cognitive neuropsychology as well as experimental methodology and statistics. The EMC research group is, under the present four-year contract, associated with the Language Dynamics Research Group (DDL), UMR 5596, CNRS University Lumière Lyon 2.

The EMC research group consists of three teams: the Visual process team, the Language process team and the Memory and emotion team.

The work of the Visual Process team concerns early as well as late visual mechanisms, employing different methods such as psychophysical method, neuropsychological dissociation, cognitive psychopathology, neuropsychopharmacology, computer simulation and functional cerebral imagery, and is organised along three main axes. The first axis concerns the study of the effects of selective attention and learning on visual integration mechanisms. The second axis is focused on the study of involuntary visual attraction through impertinent information stemming from changes in the subject's immediate environment, whilst the third axis concerns identification of functional sub-systems involved in the processing of visual spatial information.

The work of the Language Process Team is also organised along three main axes. The first concerns the study of the emergence of language in children and patterns of the earliest human language. Particular attention is given to inter-individual variability in language acquisition and development of capacity of undivided attention during communication between a child and an adult.
The second axis deals with phonological processing during reading. Here research is focused on the sensitivity of the adult reader (both the hearing and the deaf) to phonological aspects of the written word. Research also involves children who are of normal reading ability, deaf children and dyslexic children. The third research axis is aimed at theoretical, experimental and simulatory development of the study of reading strategies, of comprehension and the memorising of linguistic and non-linguistic information.

The work of the Memory and Emotion team is organised along five axes. The first axis concerns activation and integration of knowledge in long-term memory. The second axis concentrates on capacity for inference and organisation of knowledge, with studies based on different types of knowledge. The third axis centres around the influence of auditory sensory deficiency on explicit and implicit memory capacity, the fourth axis concerning the functioning of operational memory when exposed to emotional strain. The main objective is to study modification and performance of tasks related to operational memory, depending on emotional state created using experimental induction methods. Finally, the fifth axis deals with the study of the functional architecture of emotional mechanisms.
