The ability to detect and interpret stimuli from the environment. Examples include vision, hearing, taste, smell, and touch.

Senses have evolved to provide information about the world that is relevant to survival. They detect important features that help an organism survive in its environment.

The sense of position and movement of the body. It helps us understand where our body parts are in space and how they are moving.

The ability to sense pain. It serves as a warning system to protect the body from harm.

The sense of temperature. It allows us to detect the temperature of the environment and objects.

Perception is not always an accurate reflection of reality. Illusions can lead to misinterpretations of what is actually happening.

Experiences where perception deviates from reality, often caused by factors like visual stimuli and how our brains interpret them.

The eye's structure resembles a camera, but it doesn't simply capture an image. The brain interprets the light patterns received by the eye to create a visual perception.

Information is processed in a bottom-up manner, starting from sensory input and moving towards higher-level cognitive processes.

The sensory information we receive is much richer than previously thought, providing ample cues about the environment.

We actively interact with the environment, extracting information through movements and actions.

Perception is viewed as a computational process, involving data acquisition, processing, storage, and recall.

Modern approaches to studying perception involve investigating different aspects of the perceptual process, including psychophysics, neurophysiology, and brain imaging.

The initial stage of perception where sensory receptors convert physical stimuli into neural impulses.

Our perceptions don't always match reality due to factors like illusions, biases, or limitations of our sensory systems.

An illusion is a distortion of perception, where our senses or brain misinterpret sensory information, causing us to see, hear, or feel something that isn't actually there.

These illusions demonstrate how easily our perception of size and length can be distorted by the context surrounding the objects.

Visuals like the Necker cube or Rubin's vase present the same image, but our perception switches back and forth between two or more possible interpretations.

Ambiguous figures showcase how perception can be dynamic and change over time, even when presented with the same visual information.

These figures are also called bistable images. One example is the 'Old Lady/Young Lady' picture, where viewers can see either a young lady or an old lady.

Ambiguous figures can evoke different interpretations even among individuals. People might see different things consistently, like #thedress, which some saw as white and gold and others as black and blue.

Auditory stream segregation is a phenomenon that demonstrates our ability to separate sounds into different streams, even if they overlap.

Similar to visual ambiguous figures, ambiguous sounds can lead to different interpretations that can persist over time. An example is the 'Laurel or Yanny' audio, where some hear 'Laurel' and others hear 'Yanny.'

The tendency for our perception of an object's color to remain consistent even when the lighting conditions change.

The processing of visual information that is influenced by prior knowledge and expectations.

The amount of light energy emitted by a source.

The distance between two consecutive peaks of an electromagnetic wave, determining the color we perceive.

The process by which photoreceptors in the retina convert light energy into electrical signals that the brain can understand.

Specialized cells in the retina that are sensitive to light intensity and contribute to our perception of brightness.

Specialized cells in the retina that are sensitive to different wavelengths of light and contribute to our perception of color.

The processing of visual information that is based on the input received by the eye.

A school of psychology that emphasizes the importance of the whole form or configuration in perception, rather than just individual elements.

The Gestalt principle that suggests elements that are close together tend to be grouped together as a single unit.

The Gestalt principle that suggests elements that are similar in some way (e.g., shape, color, orientation) tend to be grouped together.

The Gestalt principle that suggests elements that move together tend to be grouped together.

The Gestalt principle that suggests elements that form smooth, continuous lines tend to be grouped together.

The Gestalt principle that suggests elements that form complete figures, even if incomplete, tend to be grouped together.

The Gestalt principle that suggests elements that are balanced or symmetrical tend to be grouped together.

The central idea in Gestalt psychology, stating that the simplest and most stable perceptual organization is the one that is most likely to occur.

An illusory contour is a perceived edge that is not present within the stimulus itself, but is created by the brain based on the surrounding information.

The Gestalt psychologists argued that perception is not simply the sum of its parts, but rather a holistic process.

The phenomenon where our perception of brightness is influenced by our knowledge of how light interacts with 3D objects, leading to the interpretation of identical luminance as different brightness.

The tendency of the visual system to maintain the perceived brightness of an object despite changes in the amount of light falling on it.

A type of receptive field where the center is excited by light, but the surrounding area inhibits the firing of the neuron.

The inability to perceive colors due to the absence or dysfunction of cone cells in the eye.

A condition where individuals have only two functioning cone types, resulting in limited color perception.

A more common form of color deficiency where one of the cone types is defective but not completely absent.

A test used to assess color perception by displaying colored figures against a background of similar colors, often used to detect color blindness.

A phenomenon where retinal ganglion cells receive both excitatory and inhibitory input from different cone types, creating distinct color pathways.

A visual phenomenon where prolonged exposure to a particular color leads to a perception of its complementary color after the exposure ends.

A visual illusion that demonstrates the interaction between opponent color processing, where a lilac-colored object is perceived as having different colors depending on surrounding elements.

The combination of light wavelengths that leads to the perception of a specific color.

The different types of photoreceptor cells in the retina that are sensitive to different wavelengths of light, contributing to color perception.

The primary photoreceptor cells in the retina that are responsible for vision in low-light conditions.
