Causes of Social Behavior II: Cognitive Processes

217
Cognitive processes affect social behavior by guiding how individuals perceive, interpret, and respond to social stimuli. These mental processes enable individuals to assess others' behaviors, attribute causes to their actions, and form expectations based on past experiences.Causes of Behavior and Social JudgmentsIndividuals determine the causes of others' behaviors by distinguishing between personal traits and external circumstances. For example, if a friend frequently arrives late, an...

Perceptual Constancy01:12

Perceptual Constancy

1.5K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Cognitive Dissonance

37.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Framing Effects

8.0K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Language and Cognition01:27

Language and Cognition

820
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Cognitive Therapy01:25

Cognitive Therapy

1.3K
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Summary
This summary is machine-generated.

Cognitive load, or the demands on working memory, can influence early visual perception, challenging the idea that these processes are entirely independent. Findings suggest cognitive load can affect visual processing under certain conditions.

Area of Science:

  • Cognitive Neuroscience
  • Visual Perception
  • Psychology

Background:

  • Early visual processing, particularly contrast perception, was thought to be autonomous.
  • Spatial attention is known to modulate early visual perception.

Purpose of the Study:

  • To investigate if cognitive load impacts contrast-based early visual processing.
  • To determine the relationship between higher cognitive functions and early perceptual stages.

Main Methods:

  • A dual-task paradigm was employed.
  • Participants performed three distinct early visual tasks concurrently with a working memory task.
  • Cognitive load was manipulated via the working memory task.

Main Results:

  • Experiment 1 indicated that cognitive load significantly modulated early visual processing.
  • Experiments 2 and 3 did not show significant effects of cognitive load.
  • Results suggest cognitive load effects can penetrate early visual stages under specific circumstances.

Conclusions:

  • Early visual processing and higher cognitive functions may not be entirely independent.
  • Cognitive load can influence early visual perception under certain conditions.
  • Challenges the traditional view of autonomous early visual processing.
