Summary
The traditional view of the brain overemphasizes the cerebral cortex for higher functions. This article argues that subcortical structures are crucial for cognition and behavioral regulation, challenging the corticocentric bias in neuroscience.
Area of Science:
- Neuroscience
- Cognitive Science
- Neurobiology
Background:
- The dominant corticocentric model posits the cerebral cortex as the primary center for higher brain functions.
- Subcortical structures have historically been relegated to secondary or non-existent roles in cognition and behavioral regulation.
Observation:
- This article identifies a conceptual bias in the prevailing corticocentric view of the human brain.
- This bias has detrimental implications for current research and practices within the cognitive neurosciences.
Findings:
- The corticocentric perspective is deemed myopic, limiting a comprehensive understanding of brain function.
- Higher brain functions, including cognition and behavioral regulation, may critically depend on the integrity of subcortical structures.
Implications:
- Re-evaluating the role of subcortical structures is essential for advancing cognitive neuroscience.
- A more integrated model of brain function, incorporating both cortical and subcortical contributions, is needed.
- This shift in perspective can lead to improved diagnostic and therapeutic strategies for neurological and psychiatric disorders.

01:17Cognitivism
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.

01:24Revisionist Views of Adolescent and Adult Cognition
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are themselves.
01:20Introduction 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.

01:12Hindsight Biases
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?
01:25Motivational Bias
Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...
01:09First Impression
First impressions play a crucial role in social perception, shaping how individuals assess others in professional, academic, and interpersonal contexts. Psychological research highlights the significance of cognitive biases, such as the primacy and recency effects, which influence how people interpret and recall information.The Primacy Effect and Cognitive AnchoringThe primacy effect describes the tendency for initial information to impact judgment disproportionately. When individuals encounter...
