Cognitive Psychology

Cognitive Psychology

1. 98% of thinking is unconsious

2. Recruited neural structure is recruited, if you perform a similar action over and over again those neural pathways get strengthened.

3. Neurons have ultimately have to be connected to the outside world in order to get a sense of context.

4. neural darwinism

   • seth and baars (2005) https://www.sciencedirect.com/science/article/pii/S1053810004000923

5. Spike time plasticity?

6. gating? and modulation

7. semantic embodiment

   • embodied theories, grounded in bodily action and perception.

8. Category specific semantic defecits Caramazza the harvard professor in cognitive neuropsychology.

   • Sensory functional theory and domain specific hypothesis.

9. The collins and quillian model.

   • Allows for cognitive economy
   • Hierarchical model
     • Animals lower down in a category inherit the characteristics of those a level above them.
   • Contrasts with Smith's feature comparison model.
     • Consists of defining features and Characteristic features.
     • Not as efficient as the collins and quillian model as it is not hierarchical therefore a lot of energy is lost.
     • Many semantic models are tested using sentence verification tasks.
       • Fast yes, fast no and intermediate comparison reaction times... interesting.
   • Typicality effect: the degree to which items are seen as central members in a category.
     • This brings us into the concept of semantic relatedness and semantic distance.

10. phonemes: sounds in a language

    • Language
      • Not every language has the same phonemes as another
      • syntax: word order converys meaning.
        • word order and phrase order changes the whole meaning of sentences.
