Q

De spatiële Cue-ing taak van Posner is een voorbeeld van

A

Exogene oriëntatie (aandacht wordt extern gedreven door stimulus)

Endogene oriëntatie komt voor wanneer oriëntatie/aandacht wordt gestuurd door persoon zelf

Q

Change blindness

A

Fenomeen waarbij we veranderingen in het gezichtsveld niet opmerken
- pariëtalle hersengebieden betrokken
- heeft dus te maken met beperkingen van het aandachtssysteem en niet viesie (pariëtale gebieden liggen buiten het centrale visuele systeem)

Q

Inattentional Blindness

A

men is niet bewust van een volledig zichtbare visuele stimulus omdat aandacht ergens anders is

Q

Pseudoneglect

A

mensen hebben lichte neiging om de rechterzijen om hen heen te negeren en meer aandacht te hebben voor de linkerzijde (rechter pariëtaal kwab heeft dominantere rol in spatiële aandacht)

Q

Neurons in the laterall parietal (LIP) area

A

respond to unexpected stimuli and stimuli that are task-relevant

22
Q

Biased Competition Model (Desimone + Duncan)

A

Serial processing emerges at motor stages

23
Q

Covert Orienting

A

prepared but not executed action plan (e.g. Saccade)

24
Neglect
associated with right inferior parietal lobe
25
Corbetta + Schulman
right temporo-parietal region = circuitbreaker
26
Optiche ataxie
niet in staat om te grijpen - wordt veroorzaakt door schade aan de occipitopariëtal junction (onderdeel dorsale route) - failure to integrate visual + motor
27
Visuele agnosie
object niet herkennen, slechts losse elementen zien
28
perseveratie
blijven herhalen van een actie die niet meer relevant is
29
Frontale Apraxia
actie-disorganisatie syndroom - falen in het uitvoeren van routine taken die bestaan uit verschillende subdoelen, waarbij er geen tekortkoming in object herkenning is
30
Utilization behaviour
impullsief gedrag tov objecten in de omgeving
31
Dorsaal WHERE - occipitaal naar pariëtaal
Ventraal What - occipitaal naar temporaal
32
Changes in basal ganglia motor circuit with Parkinsons
increasing output of the indirect pathway and decreasing the output on the direct pathway
33
Lateral Premotor cortex is associated with acting with objects in the environment
34
Contention Scheduling
specific mechanism thought to be responsible for selecting a particular schema to be enacted in the SAS model
35
Human Analogue of Monkey Area F5
Broca's Area
36
Neurons in the Anterior Intraparrietal Area
code action-relevant properties of objects (specific shapes, sizes and orientations)
37
Modal Model (atkinson + shifrin)
divides memory into short-lived registers, general purpose short-term store and long-term memory
37
Silently mouthing irrelevant words while performing a memory task impairs the articulatory Loopp
Baddeley
38
Long-terrm potentiation represents an increase
in the responsiveness of post-synaptic neurons
39
Dorsolateral Prefrontal region
active manipulation/monitoring
40
Damage to orbitofrontal cortex
- socially disadvantageous behavior - perrform well on other executive functioning
41
Sociopathy
anti-social personality disorder
42
test moving beads (tower of london)
43
According Goldman-Rakic working memory model
prefrontal activity provides a mechnism for refreshing information stored in posterior regions
44
Multiple Demand Network
Duncan
45
Prefrontal neurons respond to task rules

46
Repetitive TMS over left DLPFC results in
less random and more familiar sequencesmo
47
itoring-related activity reflects
level of confidence
48
Aron
right ventrolateral prefrontal region relates to inhibition
49
Left prefrontal cortex
executive function task setting
50
Human connectomics
there are more synaptic connections then there are DNA bases in the genome
