Reasoning and Reading in Adults. A New Reasoning Task for Detecting the Visual Impendance Effect Panagiotidou, Elpida; Serrano Chica, Francisca; Moreno Ríos, Sergio The visual impedance hypothesis states that at the time of reasoning, the reading context provokes visual images, which may add irrelevant details to an inference and thus could hamper reasoning. This study aims to create a new visual version of a reasoning task, similar to the traditional propositional task of relational syllogisms, but based on visuospatial components. Using such a task, it would be possible to investigate the deductive ability of relational inferences in tests without the need for reading. Two reasoning tasks were used and measures of working memory, visuospatial memory, intelligence, and reading comprehension were taken. The participants were 61 university students without reading difficulties. Results show that both versions of the reasoning task work similarly in finding the main reasoning effects expected. Findings support the visual impedance effect, that is, fewer correct responses in problems with imaginable contents than with neutral ones. They indicate that this new visual task could be used to explore reasoning skills without reading being involved, and this would be useful for testing reasoning in people both with and without reading difficulties.
