Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In the back of everyone's eye is a small piece of neural tissue called the retina. The retina has photosensitive cells that respond to stimulation by light. The responses of these cells are sent into the brain through the optic nerve, a bundle of neural fibers. In each retina there is a place somewhere in the periphery where the outputs from retinal cells collect and the bundled optic nerve exits to the brain. At that location,...

An Introduction to Cognition

2023
Cognition encompasses mental processes such as memory, perception, decision-making reasoning and language. Cognitive scientists are using a combination of behavioral and neuropsychological techniques to investigate the underlying neural substrates of cognition. They are interested in understanding how information is perceived, processed and how does it affect the final execution of behaviors. With this knowledge, researchers hope to develop new treatments for individuals with cognitive...

The Staircase Procedure for Finding a Perceptual Threshold

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Psychophysics is the name for a set of methods in perceptual psychology designed in order to relate the actual intensity of stimuli to their perceptual intensity. One important aspect of psychophysics involves the measurement of perceptual thresholds: How bright does a light need to be for a person to be able to detect it? How little pressure applied to the skin is detectable? How soft can a sound be and still be heard? Put...

Creating Objects and Object Categories for Studying Perception and Perceptual Learning

We describe a novel methodology for creating naturalistic 3-D objects and object categories with precisely defined feature variations. We use simulations of the biological processes of morphogenesis and phylogenesis to create novel, naturalistic virtual 3-D objects and object categories that can then be rendered as visual images or haptic objects.

Perceptual Constancy

Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy. Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...
FAQs
Attention determines which aspects of sensory information receive emphasis, while contextual cues help organize and interpret those details. The same stimulus may therefore acquire different meaning depending on what a person notices and the surrounding situation. Clinically, examining these influences can clarify why perception and responses vary across settings or circumstances.
Expectations and memory provide interpretive context when sensory information is incomplete or unclear. They can influence the meaning assigned to an ambiguous stimulus, especially when it carries emotional significance. Evaluating this interaction helps clinicians understand whether a recurring response reflects the person’s perceptual interpretation, remembered experience, current expectation, or a combination of these factors.
Emotionally significant stimuli may receive particular attention and acquire meanings that affect subsequent responses. Because attention, perception, memory, expectations, and context interact, the resulting pattern can influence behavior and communication rather than remaining limited to immediate sensory experience. This makes emotionally relevant situations important when describing how a person interprets and responds to events.
Clinical evaluation examines recurring differences in perception and cognition alongside associated symptoms and their effects on behavior, communication, and daily functioning. Clinicians consider the situations in which the pattern appears and the meanings assigned to relevant stimuli. This structured description supports a clearer account of the person’s experience without treating one perceptual response as sufficient evidence by itself.
Recognizing a recurring pattern can add clinically relevant information to symptom assessment and help distinguish how different conditions may affect perception, cognition, behavior, or communication. The findings can also inform treatment planning by identifying functional effects that require attention. Interpretation remains part of a broader clinical evaluation rather than a standalone diagnostic conclusion.
They provide a way to investigate how attention, perception, memory, expectations, and context contribute to experiences associated with mental and neurological conditions. Researchers can relate these cognitive mechanisms to symptoms, behavior, communication, and daily functioning. Such work may strengthen descriptions of clinical presentations and improve understanding of the processes underlying differences in perception and cognition.
