    concentration on something at the cost of other things
  2. cocktail party effect
    your name is very salient and important to you
  3. neglect
    • deals with right parietal lession
    • neglect of the left visual field
  4. balints syndrome
    • bilateral parietal lesion
    • percieve one object at a time
    • cannot reach for object in space
    • cannot direct gaze and maintain it
  5. extinction
    • neglect of the contralesional stimulus when stimuli are presented simultaneously in the 2 visual field
    • great if 2 stimuili are identical
  6. frontal lobe
    deployed cognitive resources in a goal- directed manner
  7. ventromedial prefrontal cortex
    • deals with how emotions and cognition interact
    • important for shifitng strategies
  8. dorsolateral
    handles things that deal with nonemotions
  9. wisconsin card sorting task (WCST)
    • given a deck of cards and asked to sort cards however you want
    • looking for how quickly a patient can shift out of one sorting strategy to another
  10. psychological inertia
    • prefrontal damage symptom
    • -difficulty in starting an action, motivalional problems
  11. persevation
    • prefrontal damage symptom
    • -inability to shift action according to changing task demands
  12. environmental dependency syndrome
    • prefrontal damage symptoms
    • -some object in the environment triggers action
  13. left frontal damage
    poor recency judgment for verbal
  14. right frontal damage
    poor recency judgment for nonverbal
  15. working memory
    online temporary maintenance of task- relevant info
  16. maintenance in working memory
    • right ventral prefrontal cortex does spatial
    • left ventral pfc handles object (symbolic) info
  17. manipulation in working memory
    bilateral dorsal prefrontal activation for spatial and object working memory
  18. affective neuroscience
    the study of emotions
  19. galvanic skin response or skin conductane response
    • measure electiricty conductance over skin
    • when you are aroused you sweat
  20. orbitofrontal
    undersize of frontal lobe
  21. ventromedial
    area sitting right above your eye sockets and in the middle of the frontal lobe
  22. amygdalae
    • in medial temperol lobe anterior to the hippocampus
    • critical role in ascribing affective meaning to stimuli
  23. Urbach- Wiethe syndrome
    • bilateral amygdala damage
    • -impaired memory for emotional portion of stories
  24. neural tube
    front runner to central nervous system
  25. prenatal
    how neuron form, where, how do they end up where they need to be
  26. postnatal
    what kind of changes take place
  27. precursor cells (neural stem cells)
    undifferientiated cells that will form glial cells or neurons
  28. raidal glia
    • cell which radiate outward from ventricular zone and guide cells on migratory paths
    • -become astrocytes
  29. schizophrenia
    • onset 16-30 years
    • prevalence-1% of population
    • higher prevalence in males (15-25 onset)
  30. positive symptoms
    • show behaviors they should not have
