Lecture A: A Memory Reference and Scientific Method
Dr. Pfleugl: Slichter Hall 2875, DrPfleugl@gmail.com
Research papers for labs A, D, and G; one week to write; due weeks 2, 5, 8
(C)MIT = (Computerized) Memory Inference Test
Neuropsychology: studies relationship between brain and behavior
Assumes that different brain areas are involved in different types of behaviors
Measuring behaviour could allow one to determine how different brain areas are funcitoning
Could be helpful to determine if individual is suffering from cognitive disorder (e.g. memory or
attention) or could help identify a particular medical/neurological condition
Will look at ADHD
Left and right brain functions
Left: language, logic, critical thinking, math, science, etc.
Right: spatial awareness, creativity, etc.
Frontal lobe: functions, thinking, planning, organizing, problem solving, emotions, behavioral
control, personality
Motor Cortex: movement
Sensory cortex: sensations
Parietal lobe: perception, making sense of the world, arithmetic and spelling
Occipital lobe: vision
Temporal lobe: memory, understanding, language
Motor and sensory cortex are contralateral → one side of brain controls opposite side of body
Outer areas of brain: higher cortical areas → cognition, language, visual and attention abilities
Inner areas: sub-cortical areas → survival needs (thirst, wakefulness, breathing)
How is cognition measured?
Most measures are paper and pencil type tests → painless and involve answering questions
Tests are stnadardized w/ published age, education, and gender norms, whic assesss a
range of area of cognitive functioning
We still have to obtain more culturally fair tests
E.g. Stroop test (color naming)
Results:
word reading=fast; occipital lobe → wernicke’s → broca’s → frontal lobe
color naming=slower; occipital lobe → other side of brain → wernicke’s → brocas
→ frontal lobe
color-word interference=slowest; frontal lobe needed to make a decision (Frontal
Lobe inhibition → impulsivitiy)
MANY neruopsych domains evaluated (memory, motivation, attention, language, skills, etc)
MIT=memory interference test
Orignated from study to explore nature and prevalence of neurocognitive disorders due to HIV
in persons living in different geographical and sociocultural contexts
Tech + MIT = CMIT → LOTS of added benefits
CMIT structure:
Complete demographic/lifestyle questionnaire first
Presented w. Book 1 filled with pictures to memorize
Presented with set of pics, must identify pictures they just saw from book 1

Only pages 1-3 are available for preview. Some parts have been intentionally blurred.

Then presented w book 2 pictures to memorize, must not let book 1 memories interfere
Task becomes more difficult to inhibit past memories of pictures
Book 4 requires you to remember where you first saw those pictures
Last trial = simple reaction test in which one responds “yes” or “no” to a particular picture
