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...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University One thing becomes very salient after basic exposure to the science of visual perception and sensation: what people see is a creation of the brain. As a result people may fail to see things, see things that are not there, or see things in a distorted way. To distinguish between physical reality and what people perceive, scientists use the term awareness to refer to what people perceive. To study awareness, vision scientists often...

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...
FAQs
Motion perception sensitivity depends on temporal comparison, not merely on seeing a single image. Neural circuits evaluate how retinal signals change across time and relate those changes to ongoing background motion and signals from vestibular and proprioceptive systems. This integration helps the nervous system distinguish meaningful movement from sensory changes produced by the observer’s own body.
The retina supplies changing visual information, while visual motion pathways analyze its direction and speed. Vestibular signals contribute information about head and body movement, and proprioception reports body position. Their combination provides a broader reference for interpreting motion than vision alone, which is particularly relevant when visual surroundings and self-motion produce overlapping sensory changes.
Comparing an object’s movement with background and self-motion is essential because the same retinal change can have different meanings. A shift may reflect movement of the object, movement of the observer, or both. Motion perception sensitivity therefore reflects coordinated sensory processing rather than an isolated visual response, offering a way to study spatial orientation and balance-related function.
Clinical or research assessment can use motion perception sensitivity to characterize how a person processes changing sensory information. The resulting profile may help characterize visual or neurological dysfunction and broader problems involving balance or spatial orientation. Its value increases when interpreted alongside the relevant sensory systems, because an altered response may reflect disrupted integration rather than vision alone.
In rehabilitation research, these measurements can be related to balance and spatial orientation. Investigators can examine whether sensory processing changes alongside rehabilitation or other interventions, while keeping visual, vestibular, and proprioceptive contributions in view. This makes the measure useful for studying how dynamic sensory information is handled when stable orientation and coordinated movement matter.
Motion perception sensitivity provides a framework for studying disease-related changes in sensory processing. Rather than treating an observed difficulty as purely visual, researchers can consider whether altered integration of retinal, vestibular, or proprioceptive information contributes to the finding. This broader interpretation supports investigations of neurological dysfunction, balance impairment, and changes in spatial orientation.
