PSY 102: Chapter 1-2 Study Guide Definitions: Define psychology Psychology is the study of behavior and mental processes‚ this includes peoples thoughts‚ emotions‚ perceptions‚ memories‚ reasoning‚ and biological activities. Define the cerebral cortex The layer of unmyelinated neurons (gray matter) forming the cortex of the cerebrum. The cerebral cortex is responsible for higher functions of the nervous system‚ including voluntary muscle activity and learning‚ language

THE CENTRAL NERVOUS SYSTEM Every behavior begins with biology. Our behaviors‚ as well as our thoughts and feelings‚ are produced by the actions of our brains‚ nerves‚ muscles‚ and glands. In this chapter we will begin our journey into the world of psychology by considering the biological makeup of the human being‚ including the most remarkable of human organs—the brain. We’ll consider the structure of the brain and also the methods that psychologists use to study the brain and to understand how it

1. Review the anatomy of the brain. Which portion is responsible for keeping you awake‚ controlling thought‚ speech‚ emotions and behavior‚ maintaining balance and posture? Emotions and behavior are controlled by the hypothalamus (p.455) The cerebellum is responsible for maintaining balance and posture (p.455) The reticular formation is essential for maintaining wakefulness and in conjunction with the cerebral cortex is referred to as the reticular activating system (p.450) The Broca speech

Foundations of Psychology PSY 300 Foundations of Psychology Psychology is a fairly new field of science. It is divided into major schools of thought‚ since one paradigm cannot be supported across all fields. However‚ they can all agree that something biological is related to behavior whether it is genetics or a part of the nervous system. Major Schools of Thought in Psychology Over the years‚ psychology has been splintered into seven different schools‚ including schools that no

regulate breathing. Midbrain runs from the pons to the hypothalamus enclosing the cerebral aqueduct which is the tunnel connecting the 3rd and 4th ventricles. The midbrain helps to relay information for vision and hearing. It regulates several reflexes: • Visual reflex • Auditory reflex • Righting reflex Cerebellum (Latin for little brain) is a region of the brain that plays an important role in motor control. The cerebellum is at the base and the back of the brain. The cerebellum is responsible

information to the muscles which causes them to respond. The Cannon-Bard emotional theory says that stimuli have two independent excitatory effects. These can excite the feeling of emotion in the brain and the expression of emotion in the autonomic and somatic nervous systems. This would mean that it contrasts the James-Lange theory viewing emotional experience and emotional expression as parallel processes that have no direct casual relation. The Limbic System about emotions proposed that emotional

James-Lang theory is the first physiological theory. This theory was brought to light independently by William James and Carl Lang in 1884. This is the theory that an event would spark an arousal before an emotion is displayed. It is said that the autonomic and somatic responses cause the experience of emotion in the brain. This means that a person would not display an emotion until after some kind of physical happening. The Cannon-Bard theory came about in 1915 by Walter Cannon‚ and Philip Bard. It
