1st Lesson - Perception Theory

A set of vocabulary flashcards based on the key concepts from the lecture on perception theory and the psychology of form, focusing on visual perception and its applications in fashion and psychology.

Visual Perception

The process of interpreting and making sense of visual stimuli.

Sensation

The ability to detect a stimulus and transform that detection into a private experience.

Perception

The interpretation of basic stimuli and fundamental sensations, giving meaning to detected sensations.

Psychophysics

The science that defines the quantitative relationships between physical events and psychological experiences.

Just Noticeable Difference

The smallest difference in sensation necessary to detect a difference in physical weight.

Differential Threshold

The smallest amount of change in a physical stimulus that can produce a just noticeable difference.

Weber’s Law

A principle that states the change needed to perceive a difference is proportional to the original stimulus intensity.

Absolute Threshold

The minimum intensity of a stimulus that can be detected.

Signal Detection Theory

A psychophysical theory that measures an observer’s response to a signal amidst noise.

Neural Networks

Computational structures composed of layers of nodes that mimic the way neural systems process information.

Computational Models of Perception

Models that explain how the brain processes visual information using inputs, processing, and outputs.

Bayesian Models

Models that explain perception through probabilistic inference, combining prior knowledge and current evidence.

Cones

Photoreceptors that enable sharp, full-color vision in bright light.

Rods

Photoreceptors that allow vision in low-light conditions.

Fovea

The central point of the retina where visual acuity is highest.

Photoreceptors

Cells in the retina that capture light energy and initiate visual processes.
