Subliminal Perception01:15

Subliminal Perception

782
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 Perception01:25

Factors Affecting Perception

2.7K
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...

Perception

1.1K
Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

Fixed Action Patterns01:06

Fixed Action Patterns

17.6K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Gestalt Principles of Perception01:21

Gestalt Principles of Perception

1.2K
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...

Auditory Perception01:17

Auditory Perception

1.1K
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Summary
This summary is machine-generated.

Athletes with a history of concussion show impaired vestibular/oculomotor function and altered perception of action boundaries (ABP). These deficits may explain increased musculoskeletal injury risk in concussed athletes.

Area of Science:

  • Sports Medicine
  • Neurology
  • Biomechanics

Background:

  • Concussions in athletes are linked to a higher risk of musculoskeletal injuries.
  • Altered perception of action boundaries (ABP) is a potential mechanism contributing to this increased injury risk.

Purpose of the Study:

  • To compare symptoms, neurocognitive function, vestibular/oculomotor function, and action boundary function between athletes with and without a concussion history.
  • To investigate the relationship between concussion history and functional deficits.

Main Methods:

  • Cross-sectional study involving athletes with concussion history (ConcHX) and without (NoHx).
  • Utilized Immediate Postconcussion Assessment and Cognitive Testing (ImPACT), Post-Concussion Symptom Scale (PCSS), Vestibular-Ocular Motor Screening (VOMS), and Perception-Action Coupling Task (PACT).
  • PACT specifically measured the accuracy of perception of action boundaries (ABP).

Main Results:

  • Athletes with concussion history (ConcHX) reported more previous concussions and exhibited higher scores on several Vestibular-Ocular Motor Screening (VOMS) items, including saccades and vestibular-ocular reflex.
  • ConcHX also demonstrated longer movement and reaction times on the Perception-Action Coupling Task (PACT), indicating impaired action boundary function.
  • Significant differences were observed in saccades, vestibular-ocular reflex, and visual motion sensitivity between groups.

Conclusions:

  • Findings suggest impaired vestibular/oculomotor function and perception of action boundaries (ABP) in athletes with a concussion history compared to those without.
  • These functional deficits may contribute to the elevated risk of musculoskeletal injuries observed post-concussion.
  • Further research can enhance understanding of injury mechanisms following concussion.
