3. hormones neuron Matching biofeedback • The long, thin cells that constitute the structural and functional unit of nerve tissue along which messages travel to and from the brain – • A systematic narrowing of attention on an image, thought, bodily process, or external object with the goal of clearing one’s mind and producing relaxation – • Three semicircle canals located in the inner ear that provide the sense of balance – • The process of learning to control bodily states with the help of feedback from specialized machines – neuron Meditation Vestibular system biofeedback neurotransmitters Vestibular system meditation meditation

4. Absolute threshold hormones Matching Difference threshold hypothesis • The chemicals released by neurons, which determine the rate at which other neurons fire – • An assumption or prediction about behavior or an educated guess about the relationship between two variables that is tested through scientific research- • The smallest change in physical stimulus that can be detected between two stimuli – • A single, threadlike structure within the neuron that extends from and carries signals away from the cell body to neighboring neurons, organs, or muscles – • Chemical substances produced by the endocrine glands that carry messages through the body in blood and regulate specific body functions – Neurotransmitters Hypothesis Difference threshold Axon hormones synapse axon Neurotransmitters

5. Completion • Controls the conscious thinking processes – • The information-processing center that controls the higher brain functions, such as reading and problem solving – • Controls functions such as hunger, thirst, and sexual behavior – • Visual receptor cells in the retina that are sensitive to light but not color – • Visual receptors that are adapted for color vision, daytime vision, and detailed vision – Cerebrum Cerebral cortex hypothalamus rods cones

6. Completion • Perceptions that misrepresent physical stimuli – • The stimulation of sensory receptors and the transmission of sensory information to the brain – • The ability to notice stimuli that affect only the unconscious mind – • The ability to recognize distances and three dimensionality, develops in infancy – illusions sensation Subliminal perception Depth perception

9. Short Answers • Describe how the peripheral nervous system controls voluntary and involuntary activities. (p.156) The peripheral system is broken down into Somatic and Autonomic Systems, the somatic system controls voluntary muscles, autonomic controls involuntary muscles. The autonomic is broken down into sympathetic which expends energy and the parasympathetic which conserves energy.

10. Short Answers 2. What are the Gestalt principles of perception? Describe each principle. (p.224) Proximity-when we see a number of similar objects, we tend to perceive them as groups or sets Similarity-when similar and similar objects are mingled, we see the similar objects as groups Closure-when we see a familiar pattern or shape with some missing parts, we fill in the gaps Continuity-we tend to see continuous patterns, not disrupted ones Simplicity- we see the simplest shapes possible
