Behavior Genetics
School of thought that focuses on how much our genes and our environment influence our individual differences
Focus: How behavior is affected by genes and the environment
Combines biology and behaviorism Emphasis on the importance of both
genetic and environmental factors on behavior
![Page 65: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/65.jpg)
Evolutionary Psychology
Combines aspects of biological, psychological, and social perspectives
Behavior is explained by how the behavior may have helped our ancestors survive long enough to reproduce successfully.

Research and Research Methodology
Method of asking questions then drawing logical supported conclusions
Researchers need to be able to determine if conclusions are reasonable or not (critical thinking).
![Page 72: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/72.jpg)
Observation
Gathering of information by simply watching subjects
Can lead to bias
![Page 73: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/73.jpg)
Bias
Situation in which a factor unfairly increases the likelihood of a researcher reaching a particular conclusion
Bias should be minimized as much as possible in research
![Page 74: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/74.jpg)

![Page 76: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/76.jpg)
Participant Bias
Tendency of research subjects to respond in certain ways because they know they are being observed
The subjects might try to behave in ways they believe the researcher wants them to behave
Can be reduced by naturalistic observation
![Page 77: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/77.jpg)

![Page 81: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/81.jpg)
Positive Correlation
As the value of one variable increases (or decreases) so does the value of the other variable.
A perfect positive correlation is +1.0. The closer the correlation is to +1.0, the
stronger the relationship.
![Page 82: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/82.jpg)

Negative Correlation
As the value of one variable increases, the value of the other variable decreases.
A perfect negative correlation is -1.0. The closer the correlation is to -1.0, the
stronger the relationship.

Correlational Study
Important NOT to imply a cause and effect relationship between the variables
Correlational study does not determine why the two variables are related--just that they are related.
Correlational studies are helpful in making predictions.

Predisposition
The possibility of something happening through the genetic code
Genetics creates the potential for something
The environment may or may not trigger the predisposition

Identical Twins
Twins who developed from a single fertilized egg that splits in two, creating two genetically identical organisms
Called monozygotic twins

Fraternal Twins Twins who developed from separate
eggs; the are genetically no more similar than other siblings, but they share a fetal environment
Called dizygotic twins

Heritability
The degree to which traits are inherited The proportion of an individual’s
characteristics that can be attributed to genetics (heredity)
![Page 134: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/134.jpg)
Twin Studies
Used to determine the heritability of a given trait
Data is collected from both identical and fraternal twins on the trait
Compare the data between the two groups
Important not to conclude that a specific behavior is inherited
![Page 135: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/135.jpg)
Adoption Studies
Compare adopted children’s traits with those of their biological parents and their adopted parents
Trait similarities with biological parents: attribute the trait to heredity
Trait similarities with the adopted parents: attribute the trait to the environment
![Page 136: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/136.jpg)
Early Brain Development
Early experience is critical in brain development.
In later life continued use is necessary to maintain neural connections in the brain.

Peer Influences
Peer influence in adolescence is very powerful.
Many studies suggest a peer group is correlated with school performance, smoking, and other behaviors.

Culture
The shared attitudes, beliefs, norms and behaviors of a group communicated from one generation to the next

Norms
Understood rules for accepted and expected behavior
Consist of the “proper behavior” within a group
![Page 140: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/140.jpg)
Individualism
Giving priority to one’s goals over the goals of the group,
Defining one’s identity in terms of personal attributes rather than the group’s identification
Tend to see people as separate and independent
![Page 141: Unit 1: Intro. Psychology The scientific study of behavior and mental processes. Uses scientific research methods. Behavior includes all observable.](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649e345503460f94b2306c/html5/thumbnails/141.jpg)
Collectivism
Giving priority to the goals of one’s group (often the extended family or work group) and defining one’s personal identity accordingly
See people as connected to others Individual needs are sacrificed for the
good of the group.
