What is Behavior?00:54

What is Behavior?

8.9K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Gene-Environment Interactions

268
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Attribution Theory

12.9K
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).

The Behavioral Perspective on Personality01:19

The Behavioral Perspective on Personality

304
Behaviorists view personality as primarily shaped by environmental reinforcements and consequences. According to this perspective, behavior is influenced by external stimuli, and individuals adjust their actions based on rewards and punishments. Over time, learning histories — accumulated patterns of reinforcement — play a significant role in shaping personality. Behaviors that lead to positive outcomes are reinforced, while those resulting in negative outcomes are diminished.

Behaviorism01:28

Behaviorism

2.3K
The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...

Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

6.5K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Summary

This study challenges the concept of response strength, proposing the Multilevel Model of Behavioral Selection (MLBS) as a clearer alternative. The MLBS framework offers a more parsimonious explanation for phenomena like Pavlovian conditioning, rendering response strength unnecessary.

Area of Science:

  • Behavioral psychology
  • Psychometrics
  • Theoretical neuroscience

Background:

  • The concept of response strength and strengthening by reinforcement face theoretical challenges, including essentialist thinking and circular reasoning.
  • These issues are also prevalent in latent variable modeling within psychometrics.
  • Existing strength-based accounts lack sufficient explanatory power and can lead to conceptual misconceptions.

Purpose of the Study:

  • To clarify theoretical misconceptions associated with strength-based accounts of behavior.
  • To introduce the Multilevel Model of Behavioral Selection (MLBS) as an alternative theoretical framework.
  • To provide a more parsimonious and coherent explanation for behavioral phenomena.

Main Methods:

  • Conceptual analysis of strength-based accounts in psychology and psychometrics.
  • Introduction and application of the Multilevel Model of Behavioral Selection (MLBS).
  • Using blocking in Pavlovian conditioning as a case study to demonstrate the MLBS framework's utility.

Main Results:

  • The MLBS framework effectively prevents misconceptions arising from strength-based accounts.
  • The MLBS provides a more coherent and parsimonious explanation of behavioral phenomena, such as blocking.
  • Reconceptualization via MLBS renders the concept of response strength superfluous.

Conclusions:

  • Theoretical reconsideration is crucial for advancing behavioral science.
  • Precisely defined and theoretically meaningful concepts are essential for robust scientific explanation.
  • The Multilevel Model of Behavioral Selection offers a superior framework for understanding behavior, moving beyond the problematic concept of response strength.
