Chapter 7 Flashcards
Physiological Characteristics
The functioning of organ systems within the body.
Physiological Systems
Nervous system, cardiac system, and the musculoskeletal system.
Theoretical Bridge
Bridge between personality dimension of interest and physiological variables in order to use physiological concepts to help explain personality.
Electrodes
Sensors placed on the surface of a participant’s skin.
Telemetry
Process by which electrical signals are sent from the participant to the polygraph through Bluetooth, Wifi, or other radio waves instead of by wires.
Sympathetic Nervous System
Branch of autonomic nervous system that supports the fight-or-flight response.
Autonomic Nervous System
Part of the peripheral nervous system that connects to viral bodily structures associated with maintaining life and responding to emergencies such as the beating heart.
Electrodermal Activity (Skin Conductance)
Most obtained by electrodes or sensors placed on the skin surface. Due to sweat with arousal, skin conductance of electricity increases.
Blood Pressure
Pressure exerted by the blood on the inside of the artery walls, and it is typically expressed with two numbers: diastolic and systolic pressure.
Diastolic Pressure
Resting pressure inside the system between heart contractions. Smaller number.
Systolic Pressure
Maximum pressure within the cardiovascular system produced when the heart muscle contracts. Larger number.
Cardiac Reactivity
Greater than normal increase in blood pressure and heart rate when performing task such as backward serial subtraction.
Type A Personality
Behavior pattern characterized by impatience, competitiveness, and hostility.
Ascending Reticular Activating System (ARAS)
Structure in the brain stem thought to control overall cortical arousal.
Arousal Level (Arousability)
Extroverts have lower levels of cortical or brain arousal than introverts. Difference between both lies in their nervous systems. with extroverts showing less arousability than introverts to the same levels of sensory stimulation.
Reinforcement Sensitivity Theory
Theory based on two principles: the behavioral activation system and the behavioral inhibition system.
