Input and Intake: The need for selective attention

Input and Intake: The need for selective attention

1. Input

   • Object
     • Source of information
       • Cannot be limited
   • Process
     • Comprehensible input
   • The object of the learner's attention

2. Intake

   • How learners "internalize" the linguistic patterns available in the input
   • The product of information processing in the brain

3. Modulating information flow

   • An individual directs attention towards and maintains attention on the stimuli of relevance
   • Internal context
     • Influences and individual's selective attention
       • Understanding the input

4. THE NUCLEUS RETICULARIS THALAMI

   • All sensory information must pass before being futher processed
   • Is involved in the modulation of all communication between the thalamus and the cortex.
   • General topographical organization
     • Facilitate cerebellar processing
     • Works in concert with the cingulate gyrus
   • Synapsing
     • Thalamorcortical axons
     • Corticothalamic axons
   • Topographically organized feedback system
   • Enhance constrast among incoming sensory signals
