Sensory Modalities

1.8K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

Sensory Perception: Organization of the Somatosensory System

7.7K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

Introduction to Special Senses

Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive...

Factors Affecting Perception01:25

Factors Affecting Perception

2.0K
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...

Somatosensation01:33

Somatosensation

38.9K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Impact of Social Context on Individuals01:21

Impact of Social Context on Individuals

23
Social psychology examines how the real or imagined presence of others influences individuals' thoughts, feelings, and behaviors. A key concept in this field is the role of social context in shaping behavior. The same individual may act differently depending on the social setting, due to the varying expectations and norms associated with each environment. This context-dependent behavior illustrates the influence of social roles, which prescribe appropriate conduct in specific situations.Social...

Summary

Self-prioritization effects enhance processing of self-relevant information. This study shows self-relevance influences multisensory integration across senses, impacting attention and perception.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Multisensory Perception

Background:

  • Humans naturally prioritize self-relevant information, processing it faster and more accurately than information about others.
  • Previous research indicated social associations can trigger self-prioritization for abstract stimuli, but its hierarchical processing remains debated.
  • Limited evidence exists on social relevance's efficiency in natural, multisensory environments.

Purpose of the Study:

  • To investigate how self-prioritization operates across different processing levels.
  • To examine the functional efficiency of social relevance in multisensory contexts.
  • To determine if self-relevance modulates auditory-visual information integration.

Main Methods:

  • Three experiments involving audio-visual numerosity judgments with 40 participants each.

  • Assessed self-prioritization effects in simple perceptual tasks.
  • Investigated cross-modal attentional deployment and multisensory integration.

    • Main Results:

    • Self-prioritization effects were observed in audio-visual numerosity judgments.
    • Perception was efficiently funneled towards self-relevant information in the more reliable sensory modality.
    • Self-relevance modulated the integration of auditory and visual information into a unified multisensory representation.

    Conclusions:

    • Social relevance influences multisensory processing at both perceptual and postperceptual levels.
    • Early attentional modulations of sensory integration and later, task-dependent attentional control are key mechanisms.
    • Findings suggest self-prioritization is a flexible mechanism impacting how we process information from multiple senses.
