Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

They are obligate parasites that have no metabolic capacity, and in order to replicate, rely on host metabolism to produce viral parts that self-assemble inside host cells. Viruses are ultramicroscopic—too small to be viewed with the light microscope, visible only with...

An organism’s physical traits, or phenotype, are a product of its genotype, which is the combination of alleles (gene variants) inherited from its parents. To varying degrees, genes interact with each other and environmental factors to generate traits. The distribution of alleles and traits within a population is influenced by a number of factors, including natural selection, migration, and random genetic drift.In this video, JoVE introduces some of the foundational discoveries in genetics,...

In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation. Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if: Variable a...

Genetic Crosses

To dissect genetic processes or create organisms with novel suites of traits, scientists can perform genetic crosses, or the purposeful mating of two organisms. The recombination of parental genetic material in the offspring allows researchers to deduce the functions, interactions, and locations of genes. This video will examine how genetic crosses were influential in developing Mendel's three laws of inheritance, which form the basis of our understanding of genetics. One genetic crossing...

The three forms differ according to where the environment–genotype link enters development. Passive correlation is especially relevant to family settings because the same parents transmit genetic differences and construct the home context. Evocative correlation centers on reactions from other people, whereas active correlation centers on choices and environments made more compatible with an individual’s tendencies. This distinction helps interpret developmental pathways.
Evocative and active processes can produce different developmental routes even when the surrounding setting is not identical across people. A person’s inherited characteristics may elicit particular responses from others, while personal tendencies may also guide selection or creation of settings. Treating these as separate processes helps psychologists ask whether an association reflects social feedback, environmental choice, or both.
Genetic environmental correlation matters because exposure to a setting may itself be partly associated with inherited differences. Without recognizing that linkage, researchers could treat environmental experience as completely independent of the person’s genetic background. Examining the correlation therefore sharpens interpretation of developmental associations involving behavior, cognition, and mental health, rather than assigning all observed differences to genes or environment alone.
Behavior, cognition, and mental health are key areas in which genetic environmental correlation can shape interpretation. Differences in these traits may coincide with differences in the developmental contexts people encounter, making it important to consider both inherited characteristics and environmental exposure. The framework is therefore useful when psychology examines why people follow different developmental pathways or show different outcomes.
Researchers can use the framework to classify how a developmental context may become linked with inherited characteristics: through family provision, responses from other people, or personal selection and creation of settings. This classification does not by itself reduce development to one cause. Instead, it helps organize questions about how genetic influence and environmental exposure operate together across psychological development.
In psychological research, the framework is most useful when environmental experience and individual characteristics appear intertwined. It directs attention to the ongoing relationship between what a person inherits and the contexts that person receives, elicits, or seeks. That perspective supports more careful explanations of development, especially when interpreting variation in behavior, cognition, or mental health.
