Natural and Artificial Concepts

199
In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint...

Concepts and Prototypes

182
The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Stereotypes, Prejudice, and Discrimination

90.3K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Generalization, Discrimination, and Extinction

636
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Attitudes

28.4K
Attitude is our evaluation of a person, an idea, or an object. We have attitudes for many things ranging from products that we might pick up in the supermarket to people around the world to political policies. Typically, attitudes are favorable or unfavorable: positive or negative (Eagly & Chaiken, 1993). And, they have three components: an affective component (feelings), a behavioral component (the effect of the attitude on behavior), and a cognitive component (belief and knowledge;...

The Nativist Approach01:21

The Nativist Approach

89
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

Area of Science:

  • Cognitive psychology
  • Linguistics
  • Social science

Background:

  • Social and legal conflicts often stem from misunderstandings.
  • Quantifying semantic variation is crucial for understanding these conflicts.

Purpose of the Study:

  • To develop methods for identifying and quantifying individual differences in semantic cognition.
  • To investigate the extent of variation in word meanings within a population.

Main Methods:

  • Collected conceptual similarity ratings and feature judgments for various words.
  • Applied non-parametric clustering and ecological statistical estimation to analyze semantic data.

Main Results:

  • Identified 10-30 distinct variants for common noun meanings.
  • Found individuals are largely unaware of this semantic variation.
  • Observed a bias where people assume others share their semantics.

Conclusions:

  • Significant, unacknowledged semantic variation exists in the population.
  • This variation likely contributes to difficulties in social and political communication.
  • Understanding semantic cognition differences is key to improving discourse.
