Frequency Illusion - A cognitive bias where something you've recently noticed suddenly seems to appear with improbable frequency afterward.
Face Perception - The cognitive process by which the brain recognizes and interprets faces using specialized neural mechanisms.
Stevens' Power Law - A psychophysical principle stating that the perceived intensity of a stimulus is a power function of its actual physical magnitude.
Thatcher Effect - A visual perception phenomenon where it is difficult to detect changes to facial features when a face is viewed upside down.
Contrast Effect - The cognitive bias where the perception of something is enhanced or diminished by comparison to a recently observed contrasting stimulus.
Sensation - The process by which sensory receptors detect physical stimuli from the environment and convert them into neural signals.
Vividness Bias - The cognitive tendency to judge vivid, emotionally striking, or easily imagined information as more likely, more important, or more true than pallid or abstract information.
Salience Bias - The tendency to focus on and give disproportionate weight to information that is prominent, emotionally striking, or easily noticeable.
Affordances - The perceived and actual properties of an object that suggest how it can be used—a door handle affords pulling, a button affords pressing.
Holistic Processing - A cognitive processing style where objects are perceived as integrated wholes rather than as collections of individual parts.
Configural Processing - The perception of spatial relationships between features of an object rather than the features themselves in isolation.
Defensive Attribution - A cognitive bias where people assign more blame to a harm-doer as the outcome's severity increases, and less blame when they identify with the victim.
Pareidolia - The tendency to perceive meaningful patterns, particularly faces, in random or ambiguous visual stimuli like clouds, shadows, or textured surfaces.
Weber's Law - The just-noticeable difference between two stimuli is a constant proportion of the original stimulus intensity.
Apophenia - The tendency to perceive meaningful connections, patterns, or causation between unrelated things.
Prosopagnosia - A neurological condition characterized by the inability to recognize familiar faces despite having normal visual acuity.
Psychophysics - The scientific study of the relationship between physical stimuli and the subjective sensations and perceptions they produce.
Cocktail Party Effect - The brain's ability to focus auditory attention on a specific stimulus while filtering out other stimuli, like following one conversation in a noisy room.
Qualia - The subjective, qualitative aspects of conscious experience - the 'what it is like' quality of sensations such as the redness of red or the painfulness of pain.
Attentional Bias - The tendency to pay more attention to emotionally dominant stimuli in one's environment while neglecting other relevant information.
Gestalt Psychology - A psychological approach emphasizing that humans perceive whole patterns and configurations rather than individual components, summarized by the principle that the whole is greater than the sum of its parts.
Leveling and Sharpening - A memory distortion process where details are lost through simplification while certain elements become exaggerated over time.
Proprioception - The sense of body position and movement in space, enabling coordination and awareness without visual input.
Telescoping Effect - Cognitive bias where recent events seem more distant and distant events seem more recent than they actually are.
Flashbulb Memory - A vivid, emotionally charged memory of a significant event that feels exceptionally accurate and detailed, yet research shows is just as prone to distortion and inaccuracy as ordinary memories.
Selective Perception - The tendency to filter information based on expectations, beliefs, and prior experiences, perceiving what we expect or want to perceive while filtering out contradictory information.
Cross-Race Effect - The tendency to more easily recognize faces of one's own racial group compared to faces of other racial groups.
