In the realm of information design, understanding the interplay between cognitive load and decision accuracy is crucial. This study delves into the impact of visual complexity in data presentation on cognitive load and subsequent decision-making accuracy. We explore how the intricacy of visual elements, such as charts and graphs, influences the cognitive resources expended by individuals when processing information.

The research employs a multidisciplinary approach, drawing insights from cognitive psychology, human-computer interaction, and data visualization. Participants are exposed to various levels of visual complexity in data representations, ranging from simplistic visuals to intricate and densely packed information displays. Cognitive load is measured through established methodologies, including subjective self-reports and physiological markers, while decision accuracy is assessed through task-specific performance metrics.


Preliminary findings suggest a nuanced relationship between visual complexity, cognitive load, and decision accuracy. While certain levels of complexity may enhance engagement and information retention, there is a tipping point beyond which cognitive overload hampers decision accuracy. Understanding these thresholds is vital for optimizing data presentation strategies in diverse contexts, from business analytics to educational materials.

The implications of this study extend to fields where effective communication of complex information is paramount. By unraveling the intricate dance between cognitive load and decision accuracy in the context of visual data presentation, we aim to contribute to the refinement of design principles that facilitate optimal information processing and informed decision-making.
