Reason and Intuition01:37

Reason and Intuition

6.4K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Cognitivism

1.4K
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...

Structuralism01:26

Structuralism

625
Structuralism, an early psychological theory developed by Wilhelm Wundt and his student Edward Bradford Titchener, sought to dissect the human mind into its most fundamental components. Wundt's groundbreaking work in his laboratory set the stage for Titchener to define structuralism's goal as cataloging the "atoms" of the mind—sensations, images, and feelings—akin to how chemists identify elements of matter.
Titchener's approach to structuralism was unique. He...

Organization of the Brain

772
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...

Understanding Consciousness01:23

Understanding Consciousness

299
Consciousness can be defined as the state of being aware of and able to think about one's existence, sensations, and surroundings. It encompasses two major components: awareness and arousal. Awareness pertains to the recognition of environmental stimuli and internal states. At the same time, arousal refers to the physiological readiness to engage with these stimuli, which varies significantly between states like sleep and wakefulness.
Sleep, a crucial state, is characterized by reduced...

Introduction to Biological Bases of Psychology

3.2K
Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.
The nervous system, the cornerstone of...

Summary

We introduce the Nested States Model to link subjective experience with neurobiology. This framework reveals a shared nested structure between mental and brain states, enabling new research directions.

Area of Science:

  • Neuroscience
  • Philosophy of Mind
  • Phenomenology

Background:

  • Enactivist approaches have advanced biologically-rooted understanding of the mind.
  • Neuroscience research on subjectivity lags, lacking methods to connect experience and physiology.

Purpose of the Study:

  • To present the Nested States Model as a framework for empirical investigation.
  • To bridge the gap between subjective experience and neurobiology.
  • To align views of subjective mental states with brain activity principles.

Main Methods:

  • Developing an account of experiential states as layered (nested).
  • Drawing on phenomenology and philosophy of mind.
  • Identifying structural homology between experiential and brain states.

Main Results:

  • Experiential states are characterized as nested systems.
  • Brain activity also exhibits a nested state structure.
  • A structural homology is identified between subjective and neural states.

Conclusions:

  • The Nested States Model provides a principled means to relate subjective phenomena to neurophysiology.
  • This homology facilitates systematic hypothesis generation for mind-brain research.
  • The model aligns subjective mental states with general principles of brain activity.
