Study Notes
Priming and Memory
- Priming is a phenomenon where exposure to one stimulus influences the response to a subsequent stimulus.
- Retrograde amnesia is a type of amnesia where the patient is unable to recall events that occurred before the onset of the amnesia.
- Semanticization is the process by which episodic memory becomes semantic memory.
Brain Regions and Dementia
- The lateral temporal region is not part of the medial temporal region.
- Semantic dementia is characterized by damage to the temporal lobe, particularly the anterior temporal lobe.
- Parkinson's dementia is the most common type of degenerative (subcortical) dementia.
- In Alzheimer's disease, the stage where the patient gets lost easily and shows a change in personality is characterized by difficulty in navigating and wayfinding.
Agnosia and Brain Damage
- Apperceptive Agnosia is a condition where the patient is unable to recognize objects by sight due to damage to the lateral occipital complex.
- Akinetopsia is a condition where the patient is unable to perceive moving objects due to damage to the V5/MT area.
- Cortical Achromatopsia is a condition where the patient is unable to perceive colors due to damage to the V4 area.
Language and Cognition
- Language competence encompasses listening, reading, writing, and speaking skills in a language.
- Casey and Emmory (2005) found that 15 bimodals used at least one ASL (American Sign Language) when speaking to a unimodal.
Other
- Catatonia is a condition characterized by a lack of response to stimuli.
- The concept of multiple central executive systems is a topic of debate.
Priming and Culture
- Spanish participants showed a quick response to the priming task due to linguistic and cultural familiarity with the words "Dog" and "Pear".
