Storage

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze each...

Hierarchy of Motor Control

Hierarchy of Motor Control

The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Organization of the Brain

Organization of the Brain

The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...

Cognitive Theories: Lazarus Mediational Theory of Emotion

Cognitive Theories: Lazarus Mediational Theory of Emotion

Richard Lazarus' cognitive mediational theory highlights the pivotal role of cognitive appraisal in shaping emotional responses. According to this theory, the evaluation of a stimulus — based on personal values, goals, beliefs, and expectations — mediates the emotional response. This appraisal process is immediate and often occurs unconsciously, influencing the intensity and nature of the resulting emotion.
Cognitive Appraisal and Emotional Response
Lazarus proposed that emotions are not solely...

Functional Brain Systems: Limbic System

Functional Brain Systems: Limbic System

The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Schemata

Schemata

A schema is a mental construct that organizes related concepts, allowing the brain to process information efficiently. Upon activation, schemata facilitate assumptions about people or objects.
Two types of schemata are:

Area of Science:

Cognitive Science
Neuroscience
Behavioral Psychology

Background:

Human cognition appears complex due to the brain's extensive behavioral repertoire.
Temporal and spatial constraints significantly simplify cognitive complexity.
The brain limits goal-directed behaviors to a few independent tasks within 1-2 minutes.

Purpose of the Study:

To unify disparate perspectives on cognitive limitations.
To propose a unified framework for understanding cognitive control.
To reframe cognitive functions like attention and working memory within a scheduling problem.

Main Methods:

Conceptual analysis integrating existing research on attention, working memory, and dual-task performance.
Theoretical modeling of cognitive processes as modular and hierarchically organized.
Examination of dual-task paradigms as a means to study concurrent agenda management.

Main Results:

Cognitive limitations are best understood as constraints on scheduling behaviors for short-term goals.
Dual-task performance reflects the management of simultaneous, competing agendas.
Attention is reframed as the decision to interrupt or persevere with an agenda.
Working memory is conceptualized as the mechanism for managing active agenda states.

Conclusions:

Viewing cognition as a scheduling problem unifies diverse research areas.
Hierarchical organization and modularity are key to understanding cognitive control.
This framework offers a parsimonious explanation for attentional and working memory functions.
