Intro to Psychology
| Term | Definition |
|---|---|
| Psychology | The scientific study of behavior and mental processes |
| Biopsychology | Specializes in the biological bases of behavior |
| Experimental psychology | Methodological study of sensing, perceiving, learning and thinking |
| Cognitive psychology | Emphasis on higher mental processes |
| Developmental psychology | Changes in behavior over the life span (womb to tomb) |
| Personality psychology | Examines consistencies in people’s behavior over time and traits that differentiate us from one another |
| Health psychology | Explores relationship between psychological factors and physical ailments or disease. |
| Clinical psychology | Investigates diagnosis and treatment of psychological disorders |
| Social psychology | Studies how people are affected by others |
| Cross-cultural psychology | Focuses on the similarities and differences in psychological functioning across cultures and ethnic groups |
| Clinical neuropsychology | Focuses on relationships between biological factors and psychological disorders |
| Evolutionary psychology | Examines influence of our genetic heritage and our behavior |
| Structuralism | Focused on the basic building blocks of perception, consciousness, thinking, and emotions |
| Functionalism | Moved from structure to what the mind does and how behavior functions |
| Humanistic perspective | Free will; Natural tendency to be in control of our lives |
| Psychodynamic perspective | Behavioral influences of inner forces |
| Cognitive perspective | How people think, understand, and know about the world |
| Behavioral perspective | Focus on observable events |
| Archival research | Use of existing data in order to test a hypothesis |
| Naturalistic observation | Observation of naturally occurring behavior without intervention |
| Survey research | A sample of people are asked a series of questions about their behavior, thoughts, and attitudes in order to represent a larger population |
| Case study | An in-depth, intensive investigation of an individual or small group of people |
| Correlational research | The relationship between two sets of variables is examined to determine whether they are associated, or “correlated” ; Correlation does not mean “causation” ; Ranges from +1 to -1 |
| Variables (research) | Behaviors, events, or other characteristics that can change, or vary in some way |
| Independent variable | The variable that is manipulated by the experimenter |
| Dependent variable | The variable that is measured and is expected to change as a result of changes caused by the the experimenter’s manipulation of the independent variable |
| Dendrites | Receive messages from other neurons |
| Axons | Carries messages destined for other cells |
| Myelin Sheath | wrap themselves around the axon providing a protective coating |
| All-or-none law | Neurons are either on or off |
| Resisting state | Negative electric charge within the neuron |
| Action impulse | An electric nerve impulse that travels through a neuron, changing the cell’s charge from negative to positive |
| Excitatory messages | A chemical secretion that makes it more likely that a receiving neuron will fire and an action potential will travel down its axon. |
| Inhibitory messages | A chemical secretion that prevents a receiving neuron from firing |
| Neurotransmitters | Chemicals that carry messages across the synapse to the dendrite (and sometimes the cell body) of a receiver neuron |
| Synapse | A chemical connection that bridges the gap between two neurons |
| Neurotransmitters location | Brain, spinal cord, peripheral nervous system, |
| Neurotransmitters effect | Excitatory |
| Neurotransmitters function | Muscle movement; cognitive functioning |
| Central Nervous System (CNS) | Spinal Cord Reflexes; Sensory (Afferent) Neurons; Motor (Efferent) Neurons; Interneurons |
| Endocrine System | Hormones- affect the functioning or growth of other parts of the body; Pituitary gland- the “master gland” |
| Brain research methods | Electroencephalogram (EEG); Computerized Axial Tomography (CAT) Scan; Functional Magnetic Resonance Imaging (fMRI); Positron Emission Tomography (PET); Superconducting Quantum Interference Device (SQUID); Case Studies; Neurological Surgical Procedures |
| Brain's central core | controls such basic functions as eating and sleeping |
| Brain's cerebellum | controls bodily balance |
| Brain's thalamus | relay station for information concerning senses |
| Brain's hypothalamus | maintains homeostasis and produces vital basic behavior |
| Brain's cerebral cortex | responsible for the most sophisticated information processing in the brain |
| Brain's association areas | Apraxia |
| Brain's motor area | responsible for voluntary movements of particular parts of the body |
| Brain's speech areas | Broca’s area; Wernicke’s area |
| Brain's sensory areas | somatosensory area; auditory area; visual area |
| Brain's hemispheres | two symmetrical left and right halves of the brain that control the side of the body opposite to their location |
| Brain's lateralization | the dominance of one hemisphere of the brain in specific functions |
| Split brain patients | a person who suffers from independent functioning of the two halves of the brain |
| Introspection | A procedure used to study the structure of the mind in which subjects are asked to describe in detail what they are experiencing when they are exposed to a stimulus |
| Carl Rogers | published Client-Centered Therapy in 1951, helping to establish the humanistic perspective |
| John B. Watson | Early behaviorist, published Behaviorism in 1924. |
| Wilhelm Wundt | Establishes first psychology laboratory in Leipzig, Germany. Leader in founding instrospection. |
| William James | publishes Principles of Psychology in 1890. Leading functionalist. |
| Phrenology | a psychological theory or analytical method based on the belief that certain mental faculties and character traits are indicated by the configurations of the skull. |
| Trephination | Outdated procedure using a surgical sawlike instrument for removing circular sections of bone, esp from the skull |
| Hypotheses | Theory-based predictions stated in a way that allows them to be tested. |
| Latane and Darley's diffusion of responsibility | This occurs when observers all assume that someone else is going to intervene and so each individual feels less responsible and refrains from doing anything |
| Kitty Genovese | Bystander effect; Newspaper reports after Genovese's death claimed that 38 witnesses watched the stabbings and failed to intervene or even contact the police. This led to widespread public attention, and many editorials. |
| Biofeedback | a method of learning to control one's bodily functions by monitoring one's own brain waves, blood pressure, degree of muscle tension, etc. |
