Study Notes

Neuropsychological Test Battery

Commonly includes a measure of general intelligence, despite limitations in assessing brain damage.
Wechsler Adult Intelligence Scale (WAIS) consists of 15 subtests categorized under:
- Verbal Comprehension: Tests general knowledge and vocabulary understanding (e.g., Information, Vocabulary, Comprehension, Similarities).
- Perceptual Reasoning: Evaluates visual-spatial skills (e.g., Picture Completion, Matrix Reasoning, Block Design, Figure Weights, Visual Puzzles).
- Working Memory: Assesses ability to manage and manipulate information (e.g., Digit Span, Arithmetic, Letter-Number Sequencing).
- Processing Speed: Measures speed of information processing (e.g., Symbol Search, Coding, Cancellation).
WAIS memory subtests may overlook deficits, despite measuring various memory functions.

Mean Difference Images

Used in PET and fMRI studies to improve signal-to-noise ratio.
Involves averaging images from multiple test repetitions to emphasize common brain activity.
Creates mean difference images, spotlighting areas of consistent activity across participants.

Biopsychological Paradigms of Animal Behavior

Behavioral paradigms help assess species-common behaviors in laboratory rats.
Species-common behaviors include actions like grooming, eating, and defending.
Open-Field Test measures anxiety and activity; low activity and high fecal bolus counts indicate fearfulness.
Colony-Intruder Paradigm studies aggressive and defensive behaviors during rat confrontations.

Cognitive Assessment and Frontal Lobe Function

Wisconsin Card Sorting Test assesses cognitive flexibility and frontal lobe integrity.
Patients often display perseveration, continuing to sort using an incorrect rule for extended trials.

Cognitive Neuroscience and Research Methods

Combines techniques to identify cognitive processes activated during tasks.
Paired-Image Subtraction Technique utilized in PET and fMRI; aids in isolating specific cognitive processes by comparing brain images during different tasks.

Learning Paradigms

Pavlovian Conditioning involves associating neutral stimuli with unconditioned responses (e.g., sound and salivation).
Operant Conditioning examines how reinforcement affects voluntary behaviors (e.g., lever pressing).

Seminatural Animal Learning Paradigms

Simulate real-life learning scenarios:
- Conditioned Taste Aversion: Rats avoid tastes associated with illness after a single exposure.
- Radial Arm Maze: Assesses spatial learning; rats navigate arms based on previous experiences.
- Morris Water Maze: Evaluates spatial memory through finding a submerged escape platform.
- Conditioned Defensive Burying: Rats bury a painful stimulus, showcasing learned avoidance behavior.

Language and Cognitive Assessment

Detailed tests for language deficits depending on speech problems (phonology, syntax, semantics).
Differentiates between reading disruption patterns, aiding diagnosis in dyslexic patients.

Research Methodologies in Biopsychology

Emphasizes converging operations, combining multiple research methods to address complex problems.
Highlights themes like neuroplasticity, evolutionary perspective, and clinical implications relating to brain and behavior relationships.
