Stereotype Content Model02:16

Stereotype Content Model

15.3K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Theory of Attribution I: Correspondent Inference Theory

351
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...

Theory of Attribution II: Kelley's Covariation Theory

409
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:...

Sympathetic Activation01:16

Sympathetic Activation

6.5K
The sympathetic division can influence tissues and organs by releasing norepinephrine at peripheral synapses and distributing epinephrine and norepinephrine through the bloodstream. In times of crisis or stress, sympathetic activation occurs, which is regulated by sympathetic centers in the hypothalamus. As a result, sympathetic activation prepares the body for physical exertion, rapid ATP production, and heightened alertness, allowing individuals to respond effectively to challenging or...

Automatic Processing and Automatic Social Behavior01:28

Automatic Processing and Automatic Social Behavior

176
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Labeling Emotion01:20

Labeling Emotion

560
Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...

Area of Science:

  • Natural Language Processing
  • Machine Learning
  • Artificial Intelligence

Background:

  • Aspect-level sentiment classification identifies sentiment towards specific targets in text.
  • Neural network models are common, with some using target information for context modeling.
  • Existing models often overlook the context's influence on target representation.

Purpose of the Study:

  • To propose an interactive neural network model, LT-T-TR, for improved aspect-level sentiment classification.
  • To address the limitation of models focusing solely on target's impact on context, by considering context's role in target modeling.

Main Methods:

  • The LT-T-TR model divides reviews into left context, target phrase, and right context.
  • An attention mechanism models the interaction between context and target phrase.
  • Separate representations are learned for context and target using this interaction.

Main Results:

  • The model effectively captures important words in both context and target phrases.
  • LT-T-TR demonstrated superior performance compared to state-of-the-art methods.
  • Experiments were conducted on laptop and restaurant review datasets.

Conclusions:

  • The proposed LT-T-TR model offers a more effective approach to aspect-level sentiment classification.
  • Interactive modeling between context and target significantly enhances performance.
  • This method advances the field of sentiment analysis through improved representation learning.
