95092218Disadvantages of experimental researchartificiality; limited scope; ethical concerns or practical realities of manipulating independent variables
95092219Descriptive/Correlational ResearchThese methods include naturalistic observation, case studies and surveys. These are distinguished by the lack of control to manipulate the independent variable under study. These methods permit investigators to only describe patterns of behaviour and discover links or associations between variables.
95092220Advantages of Descriptive/Correlational ResearchThese methods give researchers a way to explore questions that could not be examined with experimental procdures; broadens the scope of phenomena that psychologists are able to study.
95092221Disadvantages of Descriptive/Correlational ResearchINvestigators cannot control events to isolate cause and effect; correlational research cannot demonstrate conclusively that two variables are casually related.
95092222Positive correlationtwo variables co-vary in the same direction; a correlation in which large values of one variable are associated with large values of the other and small with small
95092223Negative correlationtwo variables co-vary in the opposite direction; a correlation in which large values of one variable are associated with small values of the other
95092224Strength of the correlationThe closer the correlation to either -1.00 or +1.00, the stronger the relationship
95092225PredictionAs a correlation increases in strength gets closer to either -1.00 or +1.00, the ability to predict one variable based on knowledge of the other variable increases.
95092226Correlation and CausationCorrelation is not equivalent to causation!

443170407secondary oocyteA haploid cell resulting from the first meiotic division of oogenesi (not that the cytoplasmic division in this case is unequal, producing one large cell with almost all of they cytoplasm - the secondary oocyte- and one smaller cell with virtually no cytoplasm - the first polar body.). The secondary oocyte (along with some follicular cells) is released from the ovary during ovulation.
443170408menstruationthe monthly discharge of blood from the uterus of nonpregnant women from puberty to menopause
443170409menstrual cyclecycle during which an egg develops and is released from an ovary and the uterus is prepared to receive a fertilized egg
443170410uterine cycleThe cycle that prepares the uterus for the growth of an embryo.
443170411ovarian cyclecyclic changes that occur in the ovaries
443170412follicular phaseThe first phase of the ovarian cycle, during which a follicle (an oocyte and its surroudning cells) enlarges and matures. This phase is under the control of FSH from the anterior pituitary, and typically lasts from day 1 to day 14 of the menstrual cycle. The follicle secretes estrogen during this time period.
443170413luteal phaseThe third phase of the ovarian cycle, during which a corpus luteum is formed from the remnants of the follicle that has ovulated its oocyte. The corpus luteum secretes progestrone and estrogen during this time period, which typically lasts from day 15 to day 28 of the menstrual cycle. Formation of the corpul luteum is triggered by the same LH surge that triggers ovulation, however in the absence of LH (levels quickly decline after the surge) the corpus luteum begins to degenerate
443170414proliferative phaseThe second phase of the uterine (endometrial) cycle, during which the endometrium (shed off during menstration is rebuilt). This phase of the cycle is under the control of estrogen, secreted from the follicle developing in the ovary during this time period. The proliferative phase typically lasts from day 6 to day 14 of the menstrual cycle.
443170415secretory phaseThe third phase of the uterin (endometrial) cycle, during which the rebuilt endometrium is enhanced with glycogen and lipid stores. The secretory phase is primarily under the controll of progestone and estrogen (secreted from the copus luteum during this time period), adn typically lasts from day 15 to day 28 of the menstrual cycle.

443170440orgasmA function of the reproductive system controlled by the sympathetic nervous system. In males, organs includes emission and ejaculation; in females it is mainly a series of rhythmic contraction of the pelvic floor muscles and the uterus.

443170442myotoniadelayed relaxation of a muscle after contraction
443170443coitussexual intercourse, copulation
