Concepts

Computer Vision - A field of AI that enables computers to interpret and understand visual information from the world, including images and video.
Binding Problem - The question of how the brain integrates information processed in different neural regions into unified conscious experiences.
Von Restorff Effect - A memory bias where distinctive or unusual items in a group are better remembered than common items, due to their isolation from surrounding elements.
Face Perception - The cognitive process by which the brain recognizes and interprets faces using specialized neural mechanisms.
Psychophysics - The scientific study of the relationship between physical stimuli and the subjective sensations and perceptions they produce.
Leveling and Sharpening - A memory distortion process where details are lost through simplification while certain elements become exaggerated over time.
Attentional Bias - The tendency to pay more attention to emotionally dominant stimuli in one's environment while neglecting other relevant information.
Cross-Race Effect - The tendency to more easily recognize faces of one's own racial group compared to faces of other racial groups.
Thatcher Effect - A visual perception phenomenon where it is difficult to detect changes to facial features when a face is viewed upside down.
Predictive Processing - A framework proposing that the brain constantly generates and updates predictions about incoming sensory data, with perception driven by prediction errors.
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.
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.
Visual Perception - The ability to interpret and make meaning from visual information through the interplay of the eyes and brain, shaped by both sensory input and cognitive processes.
Telescoping Effect - Cognitive bias where recent events seem more distant and distant events seem more recent than they actually are.
Top-Down Processing - A cognitive process where the brain uses prior knowledge, expectations, and context to interpret and organize incoming sensory information.
Prosopagnosia - A neurological condition characterized by the inability to recognize familiar faces despite having normal visual acuity.
Mental Imagery - The experience of perceiving something in the mind's eye without direct sensory input, involving quasi-perceptual representations across all sensory modalities.
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.
Sensory Memory - The ultra-brief retention of sensory information lasting milliseconds to seconds, serving as the initial stage of memory processing.
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.
Categorization - The cognitive process of grouping objects, events, or ideas based on shared features, enabling efficient information processing and reasoning.
Figure-Ground Perception - The perceptual tendency to separate visual fields into a prominent object (figure) and its surrounding context (ground), fundamental to how we make sense of complex scenes.
Weber's Law - The just-noticeable difference between two stimuli is a constant proportion of the original stimulus intensity.
Sensation - The process by which sensory receptors detect physical stimuli from the environment and convert them into neural signals.
Law of Pragnanz - The overarching Gestalt principle stating that the brain tends to perceive and organize visual information in the simplest, most regular, and most orderly form possible.
Closure Principle - The cognitive tendency to perceive incomplete shapes, patterns, or information as complete wholes by mentally filling in the missing elements.
Proprioception - The sense of body position and movement in space, enabling coordination and awareness without visual input.
Stevens' Power Law - A psychophysical principle stating that the perceived intensity of a stimulus is a power function of its actual physical magnitude.
Gestalt - A German concept meaning 'form' or 'wholeness,' referring to the idea that organized wholes have properties and meanings that cannot be derived from their individual parts.
Bottom-Up Processing - A cognitive process where perception is built directly from incoming sensory data without the influence of prior knowledge or expectations.
Apophenia - The tendency to perceive meaningful connections, patterns, or causation between unrelated things.
Zone of Perception - The limited, individually shaped window through which a person perceives and interprets reality, bounded by their experiences, beliefs, knowledge, senses, and cognitive filters.
Social Cognition - The study of how people process, store, and apply information about other people and social situations to navigate the social world.
Umwelt - The unique perceptual world of an organism, defined by which environmental signals it can detect and how it interprets them, meaning every species inhabits a fundamentally different sensory reality.
Frequency Illusion - A cognitive bias where something you've recently noticed suddenly seems to appear with improbable frequency afterward.
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.
Configural Processing - The perception of spatial relationships between features of an object rather than the features themselves in isolation.
Holistic Processing - A cognitive processing style where objects are perceived as integrated wholes rather than as collections of individual parts.
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.
Salience Bias - The tendency to focus on and give disproportionate weight to information that is prominent, emotionally striking, or easily noticeable.
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.
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.
Paper Tiger - A metaphor for something that appears threatening or powerful but is actually ineffectual and unable to withstand challenge.
Positivity Bias - The tendency to evaluate people, situations, and experiences more favorably than objectively warranted, especially in default or ambiguous conditions.
Pareidolia - The tendency to perceive meaningful patterns, particularly faces, in random or ambiguous visual stimuli like clouds, shadows, or textured surfaces.
Contrast Effect - The cognitive bias where the perception of something is enhanced or diminished by comparison to a recently observed contrasting stimulus.
