major issues

major issues in biological psychology

Artificial selection change in the frequencies of various genes in a population because of a breeder's selection of desired individuals for mating purposes
Autosomal gene gene on any of the chromosomes other than the sex chromosomes (X and Y)
Biological psychology study of the physiological, evolutionary, and developmental mechanisms of behavior and experience
Chromosome strand of DNA bearing the genes
Deoxyribonucleic acid (DNA) double-stranded chemical that composes the chromosomes; it serves as a template for the synthesis of RNA
Dizygotic twins fraternal (nonidentical) twins
Dominant gene gene that shows a strong effect in either the homozygous or heterozygous condition
Enzymes any proteins that catalyze biological reactions
Evolution change in the frequencies of various genes in a population over generations
Evolutionary explanation understanding in terms of the evolutionary history of a species
Evolutionary psychology field that deals with how behaviors have evolved
Fitness number of copies of one's genes that endure in later generations
Functional explanation understanding why a structure or behavior evolved as it did
Gene unit of heredity that maintains its structural identity from one generation to another
Hard problem philosophical question of why and how any kind of brain activity is associated with consciousness
Heritability estimate of the degree to which variance in a characteristic depends on variations in heredity for a given population
Heterozygous having two unlike genes for a given trait
Homozygous having two identical genes for a given characteristic
Identity position view that mental processes are the same as certain kinds of brain processes but described in different terms
Kin selection selection for a gene because it benefits the individual's relatives
Lamarckian evolution discredited theory that evolution proceeds through the inheritance of acquired characteristics
Materialism view that everything that exists is material, or physical
Mentalism view that only the mind really exists
Mind body problem or mind brain problem question of how the mind is related to the brain
Monism theory that only one kind of substance exists in the universe (not separate physical and mental substances)
Monozygotic twins identical twins, derived from a single fertilized egg
Multiplier effect tendency for small genetic or prenatal influences to change the environment in a way that magnifies the change
Ontogenetic explanation understanding in terms of how a structure or a behavior develops
Phenylketonuria (PKU) inherited inability to metabolize phenylalanine, leading to mental retardation unless the afflicted person stays on a strict low-phenylalanine diet throughout childhood
Physiological explanation understanding in terms of the activity of the brain and other organs
Problem of other minds difficulty of knowing whether other people or animals have conscious experiences
Recessive gene gene that shows its effects only in the homozygous condition
Reciprocal altruism helping individuals who may later be helpful in return
Ribonucleic acid (RNA) single strand chemical; one type of an RNA molecule serves as a template for the synthesis of protein molecules
Sex-limited gene gene that exerts its effects primarily in one sex because of activation by androgens or estrogens, although members of both sexes may have the gene
Sex-linked gene gene on either the X or the Y chromosome
Solipsism philosophical position that I alone exist or I alone am conscious
X chromosome chromosome of which female mammals have two and males have one
Y chromosome chromosome of which female mammals have none and males have one
