Perspectives on Sensation and Perception

2023
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...

Diffuse noxious inhibitory control, temporal summation and wound hyperalgesia testing are demonstrated in the obstetric patient. These tests evaluate inhibitory and excitatory mechanisms of pain processing and are here utilized to evaluate endogenous analgesia at different time-points during pregnancy and the peripartum period to help reveal individual s risk for persistent pain.

Subliminal Perception

2024
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
Excess body mass can increase stress on joints and other weight-bearing tissues, creating a mechanical source of pain that may worsen with movement or prolonged loading. Recognizing this contribution helps clinicians distinguish tissue stress from pain driven primarily by inflammation or altered nerve processing, which supports more targeted decisions about mobility, rehabilitation, and symptom management.
Inflammatory signaling from adipose tissue may sensitize peripheral nociceptors, the sensory nerve endings that detect potentially painful stimuli. Sensitized nociceptors can respond more readily or strongly, linking metabolic tissue activity with heightened pain sensitivity. This mechanism provides a reason to consider inflammatory contributors when evaluating pain that cannot be explained by mechanical stress alone.
Pain processing does not depend only on signals from joints, muscles, or skin. Adiposity-associated inflammatory activity may also modify processing in the central nervous system, changing how incoming signals are interpreted. This helps explain why pain intensity and emotional experience may not correspond directly to the amount of local tissue damage, making comprehensive assessment important.
These contributors represent different pathways that can produce or amplify symptoms. Mechanical pain may reflect stress on joints or tissues, inflammation may involve signaling molecules from adipose tissue, and neuropathic features may indicate altered nerve-related processing. Separating these patterns helps clinicians choose multimodal management rather than assuming that every symptom has a single cause.
Assessment can guide a multimodal plan that addresses the identified contributors instead of focusing on one intervention alone. Depending on the clinical pattern, care may incorporate approaches directed toward mechanical stress, inflammatory influences, pain processing, mobility, or rehabilitation. This individualized strategy is intended to support symptom control, treatment adherence, and daily functioning.
Researchers and clinicians can examine whether weight reduction or physical rehabilitation changes pain symptoms, mobility, and quality of life over time. These approaches are relevant because they may alter mechanical loading and functional capacity, while outcome assessment shows whether symptoms improve in practice. Such findings also contribute to personalized pain management research for people living with obesity.
