Stereotype Content Model02:16

Stereotype Content Model

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 categorization, a person will feel...
The Influence of Cognition on Affect01:29

The Influence of Cognition on Affect

Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be interpreted as...

Cognitive Theories: Schachter-Singer Theory of Emotion

Stanley Schachter and Jerome Singer proposed the two-factor theory of emotion, which emphasizes the interplay between physiological arousal and cognitive labeling in forming emotional experiences. This theory suggests that emotions are not simply a result of physiological responses but rather a combination of these responses and the individual's cognitive interpretation of them.
Physiological Arousal and Cognitive Labeling
According to this theory, when an individual experiences physiological...
Factors Affecting Perception01:25

Factors Affecting Perception

Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...
Trait Centrality01:21

Trait Centrality

Trait centrality refers to the degree to which a particular characteristic influences the overall impression of an individual. Some traits exert a disproportionately strong impact on perception, shaping how people interpret other attributes of a person. Solomon Asch first systematically studied this phenomenon in 1946.Asch’s Experiment on Trait CentralityAsch's seminal study demonstrated the centrality of certain traits through a controlled experiment. Participants were presented with a list of...
How Data are Classified: Categorical Data01:11

How Data are Classified: Categorical Data

A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

Summary
This summary is machine-generated.

Hedonic condensation, a reduction in preference, occurs when stimuli follow better-liked ones. This effect lessens when stimuli are perceived as belonging to different categories, aligning with range-frequency models.

Area of Science:

  • Psychology
  • Cognitive Science
  • Decision Making

Background:

  • Context stimuli influence preferences for subsequent test stimuli.
  • Hedonic contrast and condensation are related perceptual phenomena.
  • The range-frequency model explains judgment variations based on context.

Purpose of the Study:

  • To investigate the phenomenon of hedonic condensation.
  • To determine the effect of category perception on hedonic condensation.
  • To test the predictive power of the range-frequency model.

Main Methods:

  • Participants rated stimuli presented in sequence.
  • Stimuli varied in hedonic (pleasure) value.
  • Instructions manipulated perceived category distinctiveness between context and test stimuli.

Main Results:

  • A reduction in preference (hedonic condensation) was observed when test stimuli followed better-liked context stimuli.
  • This condensation effect was significantly reduced when participants were told the stimuli belonged to different categories.
  • Smaller hedonic ranges of perceived categories amplified preference magnitude.

Conclusions:

  • Category perception plays a crucial role in modulating hedonic condensation.
  • The range-frequency model accurately predicts how hedonic range affects preference magnitude.
  • Understanding context effects is key to understanding subjective preferences.
