Cognitivism

Cognitivism

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...

Introduction to Cognitive Psychology

Introduction to Cognitive Psychology

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...

Subconsciousness and No Awareness

Subconsciousness and No Awareness

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...

Information Processing Approach

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Cognitive Learning

Cognitive Learning

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...

Language and Cognition

Language and Cognition

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.

Neuroscience
Psychiatry
Pharmacology

Background:

Attentional impairment is a key symptom in psychiatric disorders, often inadequately treated.
Understanding neurobiological mechanisms of attention requires preclinical models.
Current clinical treatments for attention deficits are insufficient.

Purpose of the Study:

To review the development and validation of preclinical attentional tasks.
To highlight the utility of these tasks in psychiatric research.
To discuss their role in identifying novel therapeutic targets.

Main Methods:

Utilized the 5-choice continuous performance test (5C-CPT) and rodent continuous performance test (rCPT).
Employed cross-species translatable attentional paradigms.
Integrated preclinical neuroscience techniques for detailed mechanism analysis.

Main Results:

5C-CPT and rCPT accurately assess sustained attention (vigilance) and behavioral inhibition in animals.
These tasks predict clinical efficacy of pro-attentional drugs.
Common brain regions are engaged across species, supporting translational validity.

Conclusions:

Translational attentional tasks are crucial for understanding psychiatric disorder neuropathology.
These paradigms facilitate the preclinical testing of potential therapeutics for attention deficits.
Further research is ongoing to establish definitive neurophysiological construct validity.
