Cognitivism

3.3K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Subconsciousness and No Awareness01:15

Subconsciousness and No Awareness

761
The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.
An illustrative example of subconscious processing is its role in problem-solving. Often, individuals...

High-Level and Low-Level Awareness

862
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Introduction to Cognitive Psychology

2.9K
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

Cognitive Learning

1.5K
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Metacognition01:26

Metacognition

945
Metacognition is a conscious process where individuals are aware of their cognitive and executive processes, such as planning before solving a problem or self-monitoring during reading. For instance, a writer may need help with composing a piece. The situation involves a writer who is working on a piece of writing, but while doing so, they realize that something is missing. They notice that their characters lack depth or details. This realization occurs because the writer is reflecting on their...

Summary
This summary is machine-generated.

Cognitive penetration of vision is debated. This study argues attentional effects do not penetrate early vision because they lack directness and semantic coherence, supporting a pluralistic view of cognitive penetrability.

Area of Science:

  • Cognitive Science
  • Philosophy of Mind
  • Visual Perception

Background:

  • Zenon Pylyshyn's theory posits that cognitive effects do not penetrate early vision.
  • Critics argue attentional effects influence perception at all levels.
  • This debate centers on the nature of cognitive penetration in visual processing.

Purpose of the Study:

  • To re-evaluate Pylyshyn's claim regarding cognitive penetration of early vision.
  • To determine if attentional effects meet the criteria for cognitive penetration.
  • To propose an alternative framework for understanding cognitive penetrability.

Main Methods:

  • Conceptual analysis of cognitive penetration.
  • Examination of attentional effects in visual perception.
  • Distinguishing attentional effects from expectation and other cognitive influences.

Main Results:

  • Attentional effects do not qualify as cognitive penetration of early vision, even if they occur within perceptual processing.
  • These effects fail to meet Pylyshyn's criteria of directness and semantic coherence.
  • Existing defenses of cognitive penetration are distinguished, and attention is differentiated from expectation.

Conclusions:

  • Pylyshyn's claim that cognitive effects do not penetrate early vision is supported, but for different reasons.
  • A pluralistic approach to cognitive penetrability is advocated.
  • Understanding cognitive penetrability requires careful consideration of the nature and criteria of perceptual effects.
