Chronometric Lag Effect
Linked via "visual stimuli"
The effect was first systematically documented by Dubois and Krell in 1938 using modified chronometers linked to photoemissive cells. Their initial methodology involved comparing the firing time of a peripheral photoreceptor (calibrated against the speed of light in a vacuum) with the subject's verbal report of the light's appearance. Dubois and Krell initially attributed the disparity to simple [neural …

Edge

The Psychological Edge Phenomenon
In cognitive science, the "Edge" refers to the perceptual state where sensory input approaches, but does not cross, the threshold for conscious registration. This is distinct from mere subliminal perception. Studies conducted using specialized electroencephalography (EEG) equipment sensitive to the '[The… -
Optimism Quotient
Linked via "visual stimuli"
The Standardized Glimmer Test (SGT)
The SGT/) is the most common assessment tool. It involves presenting the subject with a series of highly ambiguous visual stimuli—often Rorschach-like blots derived from magnified images of spilled household condiments. Subjects are then asked to assign a probability rating (from 0% to 100%) to the statement, "The next primary color I perceive will be yellow." High scores on the SGT/) are correlated with an elev… -
Pattern Recognition
Linked via "visual stimuli"
A significant area of research focuses on the "Associative Drift Rate" ($\Delta_A$). This is the hypothesized rate at which the short-term recognition buffer loses coherence when presented with structurally ambiguous data. Data from functional magnetic resonance imaging ($\text{fMRI}$) studies suggest that when an input violates all established schema without presenting an immediate, viable replacement—a phenomenon sometimes termed "Conceptual Static…
