This is why neuroscience has focused on the theory of weak central coherence. A prime example here is in people who have autism spectrum disorder or some condition affecting executive functions. However, some studies tell us that this doesn’t always occur. We don’t usually hone in on the nose, mouth, etc. For example, if we observe people’s faces, we usually observe them as part of a whole. We don’t generally notice the individual parts that make it up. In the same way, when we observe an object for the first time, we also observe its representation in a global way. Below, we’ll explain the theory of weak central coherence. We do this due to an executive function known as central coherence. Our semantic system represents it in its totality. Thus, we don’t look for it by its individual parts. When we look for an object and put all our effort into finding it, we do so by taking a global image of it as a reference. ![]() These findings may be useful for a better understanding of some difficulties experienced by ASD in social contexts and contribute to therapeutic treatments.By default, we tend to process the objects around us in a global way. The analysis of the verbal reports revealed that the interpretation of the social contexts by those with ASD was not what was expected, associated with a specific focus on details. The results showed that in the group of autistic participants there was a tendency to focus on the details in both types of images. Eye-tracking technology was used to analyze how the participants looked at the images (which part of the image and for how long) and asked about what they had seen. A group of ASD and controls were asked to describe two different types of image, one showing a common social situation, the other Navon figure. This way of looking at things has been given the name “weak central coherence,” and may result in difficulties in understanding a situation or other people’s behaviors. These difficulties are commonly associated with a tendency to visually focus on specific parts of the situation (known as local processing) to the detriment of the whole situation. The findings corroborate the idea that weak central coherence may be part of the cognitive phenotype in ASD.Īutism spectrum disorder eye gaze qualitative research social cognition weak central coherence.Īutistic adults often report difficulties in interpreting social situations. Their reaction time and response duration were increased in relation to controls. Data from visual tracking by quadrants and from verbal reports suggest loss of social cues important for understanding context. A tendency to local processing, independently of the stimuli type, in the ASD participants was observed. ![]() Heatmap and fixation preferences according to the stimuli quadrants were used to investigate eye-tracking patterns. Both quantitative measures and qualitative (thematic content analysis) procedures were used to assess performance. A sample of 28 adults diagnosed with ASD Level 1 and 25 controls was submitted to a cartoon-like task with the instruction to describe social scenes and to Navon letter stimuli. ![]() In social contexts it may be expressed in difficulties to integrate social cues arising from the recognition of emotions in faces or from the environment in order to understand people's interactions. Central Coherence Weakness has been defined as a tendency for local rather than global processing that may underlie core deficits in Autism Spectrum Disorder (ASD). ![]()
