Psychophysiological Methods in Neuroscience (Text & Quiz)

Who was Phineas Gage?

• A neuroscientist who developed psychophysiological methods

• A railroad worker involved in an accident that contributed to neuroscience

• A psychologist who studied mental events and behavior

• A researcher who evaluated the meaning of experimental results

What part of Gage's brain was damaged in the accident?

• Right frontal lobe

• Left frontal lobe

• Right parietal lobe

• Left parietal lobe

What is psychophysiology defined as?

• The study of psychological disorders

• Any research in which the dependent variable is a physiological measure and the independent variable is behavioral or mental

• The study of brain injuries

• The study of human behavior

What are some examples of physiological measures mentioned in the text?

• Blood pressure and body temperature

• Blood flow or neural activity in the brain to heart rate variability and eye movements

• Muscle strength and reflexes

• Skin conductivity and respiratory rate

What do physiological measures help researchers understand?

• Only physical health

• Only mental health

• Behavior, cognition, and health

• Only emotional responses

Which of the following is an example of an invasive neuroscience method?

• Structural magnetic resonance imaging (sMRI)

• Injection of neutrally active chemicals

• Noninvasive brain stimulation

• Behavioral observation

What does psychophysiology primarily focus on?

• Replacing physiological measures with mental events

• Examining the relationship between physiology and overt behavior or mental events

• Manipulating neural activity via electrical stimulation

• Measuring the weight of the human brain

What is the purpose of using structural magnetic resonance imaging (sMRI) in psychophysiology research?

• To manipulate neural activity via electrical stimulation
