Study Notes

Speech Recovery After Stroke

Speech recovery after stroke is a complex area of study involving the brain, its electrophysiology, neuroimaging (MRI, fMRI, EEG), human-computer interaction, bio-signal processing, and natural language processing.
Case studies are in-depth investigations of individuals, families, or events, good for generating hypotheses.
Naturalistic observation involves observing subjects in their natural environment (e.g., employees at work, students in a classroom).
Surveys use questionnaires to gather self-reported data from a group of people.
Archival research uses existing records to answer research questions (e.g., children of older parents may marry later).
Longitudinal studies track variables over a long period (common in developmental psychology, e.g., marijuana use and IQ).
Cognitive methods investigate internal mental processes (e.g., attention, perception) using tasks like visual search (e.g., identifying guns/pencils).
Behavioral methods assess overt behavior (e.g., employee happiness and productivity).
Combining multiple research methods (methodological triangulation) strengthens research findings.

Research Methods in Psychology

Research in psychology follows a structured approach: theory/model → hypothesis → data collection → statistical analysis → publication.
Data collection involves observation, experimentation, etc.
Data analysis includes visualization (e.g., historical obesity rates) and descriptive statistics (e.g., mean, median).
Inferential statistics draw conclusions about populations from samples (e.g., comparing IQ scores).
Experiments use control groups, independent variables (e.g., new treatments vs. old treatments), dependent variables (e.g., depression scores), and must try to control confounding variables (factors that influence the outcome, e.g., placebo effect, correlational research confound like shark attacks and ice cream).
Correlational studies measure relationships between variables (e.g., IQ and money) but cannot prove causation.
Publication involves peer review: authors submit articles, editors assess and send to reviewers, and revised articles are assessed, accepted, or rejected.
Ethical considerations, like IRB approval and ethical guidelines (e.g., Belmont Report, Declaration of Helsinki), are crucial in research.

Biological and Cognitive Aspects of the Brain

Dualism versus determinism (free will vs. predetermined actions).
Inhibitory signals to the occipital lobe can lead to temporary blindness.
Cognitive Neuroscience examines how neurons function, including dendrites, axons, and neurotransmitters (e.g., serotonin, dopamine).
Neurotransmitters impacting behaviors like pleasure or reward.
Selective serotonin reuptake inhibitors (SSRIs) target serotonin for depression treatment.
The brain is divided into lobes (frontal, parietal, occipital, and temporal).
Lobes have specific functions (e.g., frontal lobe: emotion, reasoning, motor control; parietal lobe: touch, pain, temperature; temporal lobe: auditory processing; occipital lobe: visual processing).
Brain imaging techniques like EEG (electroencephalography), fMRI (functional magnetic resonance imaging), and MRI (magnetic resonance imaging) are used to study brain activity and structure.
Brain damage, such as stroke, can lead to consequences like speech impairment and affect development, and case studies explore these effects.
