Operant conditioning (define)
Strengthening and weakening of behaviors by systematically changing their consequences (reinforcement and punishment. (B.F. Skinner) A behavior followed by a rewarding stimulus is more likely to occur, while a behavior followed by a punishing stimulus is less likely to occur.
Operant conditioning (apply)
When a parent smiles at a child in response to a behavior, the child is more likely to repeat the behavior vs. when a parent gives a disapproving look, the child is less likely to repeat the behavior.
Phenotype (define)
A phenotype refers to the genetic material consisting of observable characteristics, including both physical and psychological characteristics.
Phenotype (apply)
Phenotypes are how an individual’s genotype are expressed in observable and measurable physical and psychological characteristics. It is part of the biological understanding of human growth and development. Phenotypes provide clues to a person’s genetic makeup and these expressions are impacted by epigenetic and environmental influences.
Punishment (define)
According to behavioral theory pioneered by B.F. Skinner, punishment is the introduction of a stimulus that will make a behavior less likely to occur. Positive punishment is when an averse stimulus is added, and negative punishment is when a pleasant consequence is removed.
Punishment (apply)
Negative punishment: spanking
Positive punishment: phone privileges revoked for a teenager
Quasi-experimental research (define)
A research design that fails to include key elements of a “pure” experiment and/or intermixes elements of both experimental and correlational studies. (also called a mixed design)
A quasi-experimental variable must be preexisting in subjects because, by the nature of the variable, a researcher cannot ask subjects to assume the risks that go with the behavior (i.e. smoking)
Reliability (define)
In research design, reliability is a measure of the consistency of test or research results. Statistically, reliability is measured by correlation coefficients.
Reliability (apply)
A researcher wants to test the reliability of a new intelligence test, to determine if it consistently measures intelligence. She uses a test-retest method, but giving the same test to the same group within a few months. Students should score about the same the second time if the test is reliable.
Separation anxiety (define)
In the grief process, separation anxiety includes preoccupation with thoughts of the deceased and also focuses on places and things associated with the deceased.
Separation anxiety (apply)
Marian recently lost her spouse. One of the dimensions of her grief is separation anxiety, which means she usually doesn’t go more than a few minutes without thinking of her late partner. Whenever she walks by the chair he watched TV in every night, she cries.
Sex-linked traits (define)
A sex-linked trait is one in which a gene is located on a sex chromosome. The implications for males may be very different than for females.
Sex-linked traits (define)
A sex-linked trait is one in which a gene is located on a sex chromosome. Generally refers to traits that are influenced by genes on the x chromosome.
Diseases caused by mutations on an X-chromosome are called x-linked diseases, and affect men more often because men only have one x chromosome (and no “backup” like women.) Since women have two x chromosomes, they become carriers if they have a sex-linked gene mutation, but do no usually show any signs of the disease. Sex linked conditions include Klinefelter syndrome, Turner syndrome, fragile x syndrome, and XYY syndrome.
Sex-linked traits (apply)
Henry is diagnosed with Fragile-X syndrome, a genetic disorder caused by abnormalities in the x chromosome. This condition is a sex-linked trait because it’s caused by a gene on the x sex chromosome.
Social referencing (define)
Social referencing is “reading” emotional cues in others to help determine how to act in a situation.
