Somatosensation01:33

Somatosensation

40.3K
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.

Visual Agnosia01:12

Visual Agnosia

451
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Prosopagnosia01:24

Prosopagnosia

376
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Higher Mental Functions of the Brain: Language01:10

Higher Mental Functions of the Brain: Language

1.9K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Lateralization01:28

Lateralization

634
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Association Areas of the Cortex01:21

Association Areas of the Cortex

6.8K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Area of Science:

  • Cognitive Psychology
  • Psycholinguistics
  • Human-Computer Interaction

Background:

  • Previous research suggested semantic processing is impaired when hands are near a computer screen.
  • This 'impoverishment' hypothesis requires further investigation across different cognitive tasks.

Purpose of the Study:

  • To test if hand proximity to a screen affects syntactic analysis.
  • To determine if word-level semantic processing is influenced by hand position.
  • To examine if picture naming performance, requiring semantic access, is affected by hand proximity.

Main Methods:

  • Four experiments were conducted involving sentence acceptability judgments (semantic/syntactic violations).
  • Tasks included word-level semantic categorization (go/nogo) and picture naming.
  • Participants completed all tasks with hands positioned near and far from the computer screen.

Main Results:

  • No significant differences were observed in sentence processing (semantic or syntactic) based on hand position.
  • Word-level semantic processing and picture naming performance remained unaffected by hand proximity.
  • The findings did not support the hypothesis of impoverished semantic processing near the hands.

Conclusions:

  • Hand position relative to a computer screen does not appear to impair semantic or syntactic processing.
  • The results challenge previous claims of semantic processing impoverishment due to hand proximity.
  • Cognitive tasks involving language and meaning access are robust to variations in hand position.
