Human behaviour

 

Human behavior is influenced by a complex interaction of biological, psychological, and social factors. Using relevant psychological theories, discuss how these three factors interact to shape an individual’s personality and behavior. In your answer, provide examples to illustrate how each factor contributes to behavior formation, and explain why understanding this interaction is important in modern psychology.

 

Psychological Influences on Behavior

 

Psychological factors encompass an individual's thoughts, emotions, learned experiences, perception, and coping mechanisms. This domain translates biological predispositions into conscious action and personality structure.

Contribution: An individual's cognitive schema (mental frameworks) determines how they interpret social situations. A child with a biologically high-reactive temperament, if constantly criticized, may develop a psychological schema of low self-worth. This perception influences their resulting behavior, such as social withdrawal or defensiveness. Learning through conditioning also shapes behavior; an adult who learned that expressing vulnerability leads to rejection will psychologically suppress that emotion.

Relevant Theory: Bandura's Social Learning Theory emphasizes self-efficacy (a psychological belief in one's ability to succeed). A person's self-efficacy, shaped by past success and observational learning, dictates their effort, persistence, and behavior when facing challenges.

 

Social Influences on Behavior

 

Social factors include culture, family environment, socioeconomic status, peer groups, and societal norms. These external forces provide the context in which behavior is expressed, reinforced, or inhibited.

Contribution: Culture dictates the acceptable range of behaviors and shapes the expression of personality traits. For example, a biologically aggressive temperament may be channeled into competitive sports in a society that values achievement (social factor), or into delinquency in a disorganized environment. Family environment provides the crucial modeling and reinforcement that dictates psychological development. A child raised in a chaotic social setting may develop chronic stress (biological impact) and adopt avoidance coping mechanisms (psychological strategy) to navigate that reality.

Sample Answer

 

 

 

 

 

Human behavior and personality are shaped by the dynamic interplay of biological, psychological, and social factors—a concept often summarized as the Biopsychosocial Model. Psychological theories help explain how these domains interact to create individual differences.

 

Biological Influences on Behavior

 

Biological factors include genetics, neurochemistry, and physiological responses, establishing the foundational temperament and potential range of behaviors.

Contribution: Genetics influences temperament (e.g., reactivity, emotional intensity), which is the early, biologically based core of personality. Neurochemistry, particularly neurotransmitters like dopamine and serotonin, affects mood, motivation, and impulse control. For example, individuals with a biological predisposition for low serotonin activity may exhibit a higher propensity for anxiety or depression, influencing their general level of risk-taking and social engagement (a behavior).
