Study Notes

Biopsychology: Definition and Divisions

Biopsychology scientifically investigates the interaction between biological processes and cognition, emotions, and other psychological processes.
Key divisions include cognitive neuroscience and comparative psychology.

Cognitive Neuroscience

Studies the neural basis of cognition and higher-order cognitive processes (thinking, memory, attention, perception).
Primarily uses non-invasive functional brain imaging techniques on human participants.

Comparative Psychology

Studies animal behavior across species to understand evolutionary, genetic, and adaptive perspectives.
Research may be conducted in laboratories or natural environments (ethological research).

Methods in Biopsychology

Electrooculography (EOG): Records eye movements by measuring the electrical potential difference between the front and back of the eyeball using electrodes near the eyes.
Electrodermal activity: Measures skin conductance level (SCL) and skin conductance response (SCR) using electrodes on fingers. SCL reflects background skin conductance, while SCR measures changes associated with specific experiences. Variations are linked to emotional stimuli and sweat gland activity.
Electrical stimulation: Uses electrodes (including microelectrodes) to stimulate brain areas, causing changes in membrane potential, triggering action potentials, and leading to behavioral changes depending on the stimulated area.

Neuropsychological Assessment

Wechsler Intelligence Scales: Assess intellectual performance in adults (WAIS-III), children (WISC-III), and preschoolers (WPPSI-R).
Halstead-Reitan Neuropsychological Test Battery: A comprehensive set of tests evaluating major cognitive, sensory, motor, and expressive functions. Reliable and valid across age groups.

Ethical Issues in Biopsychology Research

Animal research requires careful planning, appropriate surgical procedures and equipment, and prioritization of research significance to avoid unnecessary harm or pain. Post-experimental animal care is crucial for recovery.

Commonly Used Neuropsychological Tests

Wechsler Adult Intelligence Scale III (WAIS-III)
Wechsler Intelligence Scale for Children-III (WISC-III)
Wechsler Preschool & Primary Scale of Intelligence-R (WPPSI-R)
