Perspectives on Sensation and Perception

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University The study of sensation—how signals are transduced from sensory organs, like the eyes—and perception—how the brain interprets these messages—has a rich history dating back to the 19th century, when great strides were made in understanding the properties of light and how they relate to the visual system. Importantly, such sensory and perceptual processes determine what we see, feel, taste, and hear in our surroundings. However, many...

Conscious and Non-conscious Representations of Emotional Faces in Asperger's Syndrome

An EEG experimental protocol is designed to clarify the interplay between conscious and non-conscious representations of emotional faces in patients with Asperger's syndrome. The technique suggests that patients with Asperger's syndrome have deficits in non-conscious representation of emotional faces, but have comparable performance in conscious representation with healthy controls.

Subliminal Perception

Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

Factors Affecting Perception

2024
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight. An illustrative example of a perceptual set is the scenario where an airline pilot told...

Gestalt Principles of Perception

2024
Gestalt principles provide a framework for understanding how humans perceive objects as unified wholes within their context. These principles are essential in explaining the cognitive processes that make sense of complex visual stimuli by organizing them into coherent groups. One fundamental principle is proximity, which posits that objects located close to each other are perceived as a collective group. For instance, when dots are positioned near one another, the visual system interprets them...
FAQs
These factors help organize sensory signals into an accessible percept rather than leaving them as unintegrated registration. Attention influences which information becomes available, while memory and expectations provide context for interpreting it. Because ongoing brain activity also contributes, the same sensory input may produce different conscious experiences depending on a person’s current mental state and prior information.
Sensory systems can register information without that information becoming part of subjective awareness. Studying this distinction allows psychologists to ask whether a stimulus was merely processed or consciously experienced. Detection tasks, masking, and reports of subjective experience help compare these forms of processing, clarifying how awareness relates to perception, thought, and behavior.
Conscious experience does not depend only on an incoming sensory signal. The overview identifies ongoing brain activity as part of the organization and integration that produces an accessible percept. This means perception reflects an interaction between current stimulation and the brain’s continuing activity, providing an important basis for psychological theories that explain how sensory processing reaches awareness.
In a detection task, participants are presented with sensory information and asked to indicate whether they detected it, often alongside a report of their subjective experience. Comparing these responses helps researchers examine when processing becomes available to awareness. The approach is useful for separating sensory registration from consciously reported perception within controlled psychological investigations.
Masking is a method used to examine whether processing of a stimulus reaches conscious awareness. Researchers compare participants’ responses when the relevant information is presented under conditions that affect what can be consciously reported. Combined with detection measures and subjective reports, masking helps identify differences between information that is processed and information that becomes consciously accessible.
Research in this area contributes to theories of consciousness and helps explain variations in attention and perception. It can also support investigations of changes associated with neurological or psychiatric conditions. By examining detection, masking, and subjective experience, psychologists can study how alterations in awareness relate to broader changes in perception and behavior.
