Human Genetics01:28

Human Genetics

1.9K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Behavioral Genetics and Its Designs

1.3K
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

Aggression

30.6K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Causes of Social Behavior III: Biological and Environmental Influences

421
Social behavior is a complex phenomenon that arises from the interaction between biological predispositions and environmental influences. This intricate interplay shapes how individuals think, feel, and act in various social contexts. Understanding these mechanisms requires insights from psychology, neuroscience, genetics, and evolutionary theory.Environmental Influences on Social BehaviorEnvironmental factors, including temperature, odors, and visual stimuli, play a crucial role in shaping...

Evolutionary Psychology

1.2K
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

Incomplete Dominance01:43

Incomplete Dominance

32.4K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

    Area of Science:

    • Neuroscience
    • Genetics
    • Behavioral Science

    Background:

    • Human violent behavior is a complex trait.
    • It is influenced by a combination of genetic and environmental factors.
    • Investigating the genetic underpinnings of violence is an active area of research.

    Purpose of the Study:

    • To review candidate genes associated with violent behavior.
    • To discuss advances in epigenetics related to violent behavior.
    • To explore the prospects and significance of genetic and epigenetic research in understanding violence.

    Main Methods:

    • Literature review of candidate genes.
    • Review of epigenetic mechanisms (e.g., DNA methylation, histone modification).
    • Analysis of gene-environment interactions.

    Main Results:

    • Several candidate genes have been linked to violent behavior.
    • Epigenetic modifications play a significant role in mediating the effects of genes and environment on violence.
    • Gene polymorphism and epigenetic factors offer insights into individual differences in violent tendencies.

    Conclusions:

    • Genetic and epigenetic factors are crucial in the development of violent behavior.
    • Further research into gene-environment interactions and epigenetic mechanisms is warranted.
