Nerve fibers that connect the two cerebral hemispheres
Corpus Callosum
Involved in basica motivation, emotional expression, and control of the endocrine system
Contains the amygdala, hippocampus, and septal areas - involved with emotional expression
Limbic System
Motor movement - contains caudate nucleus, putamen, and substantia nigra
Basal Ganglia
Controls species-specific behaviors and influences facial expressions
Plays a practical role in arousal or alertness
Reticular Formation
Directs sensory information to the appropriate areas of the cortex
Controls vital functions such as breathing, heart rate, and blood pressure
Contains the auditory cortex and Wernicke's area
Temporal Lobe
Contains the somatosensory cortex
Parietal Lobe
Involved in higher mental functions and consists of 75 percent of the cortex
Association Cortex
Contains the motor cortex, Broca's area, and is involved in emotional expression
Frontal Lobe
Contains the visual cortex
Occipital Lobe
Secretes hormones that act in association with the sympathetic nervous system and also increases metabolism
Adrenal Gland
Secrete hormones directly into the bloodstream or lymph fluids
Endocrine System
Secrete estrogens and or androgens
Chemicals secreted into the bloodstream that influence target organs
Releases a number of hormones that influence other glands
Pituitary Gland
Regulates metabolism
Thyroid Gland
The scientific study of the behavior and mental processes of humans and other animals
Provides reliable information as opposed to subjective opinions
Scientific Method
An activity of an organism that can be observed
Tentative attempts to organize and explain a body of data, facts, or observations
Organization :Applied Psychology
American Psychological Association (APA)
Organization : Academic Approach
American Psychological Society (APS)
Involve manipulating conditions or behaviors and observing the results
Emperical tests
Scientific approach to the study of behavior that emphasizes the relationship between environmental events and an organisms behavior
Emphasizes the practical nature of the mind
Believes the relationship between the parts is more important than the individual parts
Gestalt Psychology
Emphasizes the role that free choice and conscious rational choices have on human behavior
Humanistic Psychology
Emphasized the role of the unconscious mind and sexual urges in influencing human behavior
Attempts to reduce conscious experience to its basic elements (Introspection)
Developed his approach as a result of treating emotionally disturbed individuals
Was strongly influenced by Darwins Theory of Natural Selection
Believed that people have a natural tendency to strive for self actualization or attainment of their fullest potential
Maslow and Rogers
Pioneered the stimulus - response approach to psychology and emphasized objectively verifiable phenomena
Believed that the whole of an experience was different from the sum of its parts
Wetheimer, Kohler, and Koffka
Used introspection to study mental processes
Wundt and Titchener
Artificial Intelligence
Develops computer models that stimulate complex human cognitive processes
Focuses on the relationship between physiological processes and behavior
Concerned with the diagnosis and treatment of serious psychological problems
Resulted in renewed interest in mental processes such as thinking, problem solving, and creativity
Focuses on adjustment problems that are not serious psychological problems
Concerned with factors that influence behavior and development througout the life cycle
Focuses on the study and application of teaching methods and learning
COncerned with the relationship between the working enviornment, equipment, and people
Primary activity is conducting research
Works with the legal system in a variety of ways
Concerned with how psychological and physical factors relate to the treatment and prevention of illness
Concerned with using pyschological concepts to make the workplace a more satisfying enviornment for employees and management
Focuses on the uniqueness of individuals and the key elements that provide the foundation of them
Would be interested in topics such as interpersonal attraction, conformity, and group processes
Concerned with evaluating and resolving learning and emotional problems
Commonly focuses on a specific individual
Case Study
Provides information concerning the relationship between two variables
Correlational Method
Allows for conclusions about cause-and-effect relationships
Experimental Method
Elimates the possibility of inaccurate reports supplied b the subjects either intentionally or unintentionally
Observational Method
Provides information concerning attitudes and behaviors
Survey Method
Condition or factor that the reseracher manipulates
Independent Variable
Measure of behavior in an experiment
Dependent Variable
Varies between -1.00 and +1.00
Coefficient of Correlation
Subjects who receive the independent variable
Experimental Group
Subjects who do not receive the independent variable
Control Group
Associated with deception, debriefing, and the protection of confidentiality
Ethical Guidelines
Assessed behavior in a natural setting
Naturalistic Observation
Tendency of a researcher to misinterpret behavior
Observer Bias
Used because it is usually impossible to study all members of the group or population of interest to the researcher
Would include individuals who reflect or mimic the characteristics of the entire population of interest to the researcher
Representative Sample
May not accurately reflect or mimic the characteristics of the entire population of interest to the researcher
Random Sample
The tendency of individuals to modify their behavior because of the researchers presence
Observer Effect
Involves an individual answering a written list of questions
Allowes the researcher to clarify confusing questions
Indicates that an increase in one variable is accompanied by an increase in a second variable
