520 $a Text comprehension entails a complex interaction between cognitive and linguistic factors.
520 $a The general objective of this thesis was to analyze text comprehension in older participants and in left-brain-damaged participants within the framework of a cognitive-linguistic model of discourse processing that allows for the description of measures reflecting various levels of representation (Kintsch, 1988). More specifically, we wanted to identify the levels of representation of text comprehension that may be modified in aging and/or after a left brain lesion. We also wanted to identify the cognitive function that could be responsible for these modifications. At the same time, we explored in elderly and brain-damaged participants the possible presence of compensation strategies in text comprehension. The first study allowed us to construct and validate the tasks that would be used in the following studies. Three series of three equivalent texts and nine questionnaires were developed and administered to 85 participants. The texts were constructed to highlight the features of text comprehension within each of the different levels of text representation. A second study using this protocol documented the modifications observed in the processing of the representation levels of text comprehension in aging. Eyetracking analyses were done during reading to permit inferences about reading processing and detect comprehension strategies. Specific complementary tasks were administered to evaluate memory and executive functions. The results indicated that aging influences the processing of levels of text representation depending on text characteristics and particularly on semantic load, but no compensation strategies were found. This experiment provided new knowledge about the effects of aging on text comprehension.
520 $a The third and fourth studies investigated text comprehension in six brain-damaged participants who complained of discourse comprehension difficulties although their clinical assessments did not show any problems. This complaint was objectivized by the identification of a weakness in text comprehension processing, associated with a non-linguistic cognitive deficit, and by abnormal eye movements during reading. These findings have implications for specific cognitive interventions targeting reading comprehension abilities in aphasia.
520 $a Overall, these studies emphasized the importance of assessing text comprehension with several texts and pointed out the need for clinicians to consider cognitive functioning as a whole whenever complex cognitive activities are under consideration.
