Influences on Behavior and Psychological Disorders Presentation


The study of behavior and psychological disorders is a complex field that seeks to understand the various factors that influence human behavior and the development of psychological disorders. This presentation will examine the different influences on behavior and psychological disorders, including biological, psychological, and social factors. It will explore how these influences interact and contribute to the development of different behaviors and psychological disorders.

Biological Influences

Biological factors play a significant role in shaping human behavior and influencing the development of psychological disorders. These factors include genetics, brain structure, and neurochemical imbalances.

Genetics refers to the hereditary traits passed down from one generation to another. Research suggests that certain genetic factors can contribute to the predisposition for certain behaviors and psychological disorders. For example, studies have shown that individuals with a family history of depression are more likely to develop the disorder themselves, indicating a genetic component.

Brain structure is another biological influence on behavior. The human brain is a complex organ that controls our thoughts, emotions, and behaviors. Structural abnormalities or alterations in specific brain regions have been associated with various psychological disorders. For instance, research has found that individuals with schizophrenia often have abnormal brain structures, particularly in the prefrontal cortex and hippocampus.

Neurochemical imbalances refer to disruptions in the levels or functioning of neurotransmitters in the brain. Neurotransmitters are chemical messengers that facilitate communication between brain cells. Imbalances in neurotransmitter levels have been implicated in several psychological disorders. For example, low levels of serotonin, a neurotransmitter involved in mood regulation, have been linked to depression.

Psychological Influences

Psychological factors also play a crucial role in shaping behavior and influencing the development of psychological disorders. These factors encompass cognitive processes, personality traits, and learned behaviors.

Cognitive processes refer to the mental processes involved in thinking, reasoning, and decision-making. How individuals perceive and interpret the world around them can significantly impact their behavior and emotional well-being. For example, individuals with anxiety disorders often have distorted thinking patterns and tend to interpret situations as more threatening than they actually are, leading to anxiety-driven behaviors.

Personality traits are enduring patterns of thoughts, feelings, and behaviors that differentiate individuals from one another. Certain personality traits have been associated with increased vulnerability to different psychological disorders. For instance, individuals with high levels of neuroticism, characterized by instability and negative emotional reactions, are more susceptible to developing anxiety and mood disorders.

Learned behaviors are behaviors that are acquired through experiences and interactions with the environment. Social learning theory suggests that individuals learn by observing and imitating the behavior of others. For example, children who grow up in an environment where aggressive behavior is modeled are more likely to exhibit similar aggressive behaviors.

Social Influences

Social factors, such as cultural norms, social support, and societal expectations, also have a significant impact on behavior and the development of psychological disorders. These influences shape an individual’s interactions with others and the larger society.

Cultural norms define acceptable and expected behaviors within a particular culture or society. These norms can influence individual behavior and the manifestation of psychological disorders. For instance, cultural norms regarding the expression of emotions can impact the way individuals with depression or anxiety disorders seek help and cope with their symptoms.

Social support refers to the relationships and networks of support that individuals have, including family, friends, and community. The presence of strong social support systems has been associated with better mental health outcomes and reduced risk of developing psychological disorders. On the other hand, social isolation and lack of support can contribute to the development of psychological disorders.

Societal expectations and pressures can also influence behavior and the development of psychological disorders. For example, societal expectations regarding body image and weight often contribute to the development of eating disorders, such as anorexia or bulimia.


The influences on behavior and psychological disorders are multi-faceted and encompass biological, psychological, and social factors. Understanding these influences and their interactions is crucial for comprehending human behavior and the development of psychological disorders. By recognizing the complex interplay of these factors, researchers and clinicians can develop more effective interventions and treatments for individuals experiencing behavioral and psychological challenges.
