1. Genes influence behavior by determining an organism’s capability to respond. Genes determine sensory structures in an organism, which determines how an organism perceives the world, and thus how it responds. Genes also can affect behavior by leaving an organism hereditarily predisposed towards certain behaviors. For example, scientists have noted a trend in the children of alcoholics developing their own problems with alcohol. In an animal’s evolution, and the chosen genes that come with it, influences aggression, fears and mating patterns (Santrock 14). According to a psychologist Steven Pinker, the mind works how it does because the genes that determine its function were selected to be the most beneficial (Santrock 14). 2. Reliability is when 2 or more repetitions of the same test result in the same or a consistent measure. It is “the extent to which a test yields a consistent, reproducible, measure of performance” (Santrock, 394). To measure reliability one only needs to repeat the test sufficiently to get a non-fluctuating result. Validity needs a standard. A valid measurement proves that what is said to be measured is measured. Santrock defines it as “the extent to which a test measures what it is intended to measure” (394). To measure validity one needs a broad spectrum of subjects or samples to be sure that the data are not biased. 3.
