ERP Measures of Intelligence: A Review of the Literature Recent advances in neuroscience and cognitive science have led to the development of electroencephalography (EEG) as a tool for measuring and assessing intelligence. Event-related potentials (ERPs) are a type of EEG signal that has been used to measure intelligence by providing a direct measure of cognitive […]
Introduction to the N1 Attention Effect and Selective Attention The study of human cognition relies heavily on understanding how the brain manages the constant influx of sensory information. Among the most critical processes is selective attention, the fundamental ability to prioritize salient stimuli while filtering out irrelevant noise. This mechanism allows for efficient interaction with […]
CONTINGENT NEGATIVE VARIATION (CNV) The Core Definition of Contingent Negative Variation The Contingent Negative Variation (CNV) is a specific type of event-related potential (ERP) that represents a slow, sustained negative shift in the brain’s electrical activity. This phenomenon is observed over the cerebral cortex, particularly in the frontal and central regions of the scalp, and […]
