Theory of Attribution I: Correspondent Inference Theory01:15

Theory of Attribution I: Correspondent Inference Theory

Correspondent inference theory, proposed by Jones and Davis in 1965, seeks to explain how individuals infer stable personality traits from observed behaviors. It suggests that people attribute actions to underlying dispositions rather than external circumstances, particularly when the behavior appears intentional and socially significant.Voluntary Behavior and Dispositional AttributionAccording to this theory, individuals are more likely to attribute behavior to personal traits when it appears...

Attribution 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...

Theory 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...
Fundamental Attribution Error01:14

Fundamental Attribution Error

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...
Causes of Similarity-Dissimilarity Effect01:26

Causes of Similarity-Dissimilarity Effect

The similarity-dissimilarity effect, a fundamental concept in social psychology, explains how interpersonal similarities and differences influence attraction and social interactions. This effect is supported by three key psychological perspectives: balance theory, social comparison theory, and consensual validation.Balance Theory and Cognitive ConsistencyBalance theory, developed by Fritz Heider, posits that individuals seek cognitive consistency in their relationships. When two people share...

Attribution

In social interactions, individuals frequently seek to understand the motivations and causes behind others' behaviors. This fundamental aspect of social perception, known as attribution, plays a crucial role in shaping interpersonal relationships and guiding future actions. Attribution refers to the cognitive process through which people infer the reasons behind others' behaviors, allowing them to assess character traits, intentions, and situational influences.Attribution Theory and Its...

Area of Science:

  • Computational linguistics
  • Forensic linguistics
  • Information theory

Background:

  • Authorship attribution is crucial for identifying text origins.
  • Traditional methods often rely on feature extraction and classification.
  • Compression models offer a novel approach by analyzing text compressibility.

Purpose of the Study:

  • To compare the effectiveness of different compression models for authorship attribution.
  • To evaluate the impact of various similarity measures on attribution accuracy.
  • To assess the performance of compression-based methods against traditional techniques.

Main Methods:

  • Experiments utilized three compressor types: Lempel-Ziv (GZip), block sorting (BZip), and statistical (PPM).
  • Two distinct similarity measures were applied.
  • Two different authorship attribution strategies were analyzed.
  • Evaluations were conducted on two separate text databases.

Main Results:

  • All tested compression models demonstrated similar performance.
  • The choice of similarity measure significantly influenced attribution outcomes.
  • Compression-based authorship attribution proved superior to traditional pattern recognition systems.

Conclusions:

  • Compression models provide a robust and effective alternative for authorship attribution.
  • The selection of appropriate similarity measures is critical for optimizing compression-based attribution.
  • This approach surpasses conventional methods relying on classifiers and feature extraction.
