Development and Psychopathology
|July 12, 2012
Summary
This study advances understanding of trait impulsivity by examining its development across multiple biological and psychological levels. This research offers insights into antisocial and borderline personality development, including delinquency and suicide risk.
Area of Science:
- Developmental psychopathology
- Psychiatric genetics
- Primary prevention
Background:
- Developmental psychopathology has evolved to integrate diverse fields.
- Traditional models (diathesis-stress, transactional) now incorporate multiple levels of analysis.
- The multiple levels of analysis perspective examines causal processes across various domains.
Purpose of the Study:
- To inform understanding of antisocial and borderline personality development in trait impulsive individuals.
- To extend the multiple levels of analysis perspective beyond simple gene-environment interactions.
- To develop a comprehensive developmental model of trait impulsivity.
Main Methods:
- Evaluating impulsivity across physiological systems (genetic, autonomic, hormonal, neural).
- Assessing psychological constructs (social, affective, motivational).
- Examining developmental epochs, sexes, and diverse methods of inquiry (e.g., neuroimaging, self-report).
Main Results:
- A developmental model of trait impulsivity has been formulated.
- This model enhances comprehension of a highly heritable trait.
- The model accounts for heterogeneity in behavioral outcomes like delinquency and suicide.
Conclusions:
- The multiple levels of analysis approach provides a robust framework for studying complex developmental psychopathology.
- Understanding trait impulsivity requires integrating biological, psychological, and developmental factors.
- This research contributes to a more nuanced understanding of vulnerability to antisocial behavior and personality disorders.

01:29Theory of Attribution II: Kelley's Covariation Theory
Attribution theory plays a crucial role in social psychology, helping to explain how individuals interpret the causes of behavior. One prominent model within this field is Harold Kelley's covariation theory, which provides a systematic approach to determining whether internal traits or external circumstances drive a person's actions. The model posits that individuals rely on three key types of information—consensus, consistency, and distinctiveness—to make these judgments.Consensus: Comparing...
01:26Structuralism
Structuralism, an early psychological theory developed by Wilhelm Wundt and his student Edward Bradford Titchener, sought to dissect the human mind into its most fundamental components. Wundt's groundbreaking work in his laboratory set the stage for Titchener to define structuralism's goal as cataloging the "atoms" of the mind—sensations, images, and feelings—akin to how chemists identify elements of matter.
Titchener's approach to structuralism was unique. He employed introspection, a method...

01:24Defining Psychology
Psychology is the scientific discipline dedicated to understanding both observable behavior and the internal mental processes underlying such behavior. It aims to comprehend human nature and apply this understanding to solve practical problems, enhance well-being, and improve societal outcomes. An example of psychology's application is the study of prosocial behavior, such as why and under what conditions individuals might help strangers in need. This process involves describing observed...
00:56Attribution Theory
Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958). An internal factor is an...
01:20Social Foundations of Self II: The Generalized Other
According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group effort.
02:30Naturalistic Observations
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
