Introduction to Cognitive Psychology

2.3K
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...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Chromatin Packaging

19.0K
Each human somatic cell contains 6 billion base pairs of DNA. Each base pair is 0.34 nm long, meaning each diploid cell contains a staggering 2 meters of DNA. This long DNA strand is packed inside a nucleus measuring only 10-20 microns in diameter with the help of specialized DNA-binding proteins called histones. Together they form a compact DNA-protein complex called chromatin. The chromatin is further compacted into higher-order structures. The highest level of compaction is achieved during...

Each human somatic cell contains 6 billion base-pairs of DNA. Each base-pair is 0.34 nm long, which means that each diploid cell contains a staggering 2 meters of DNA. How is such a long DNA strand packed inside a nucleus measuring only 10 - 20 microns in diameter? 
The chromatin
In combination with specialized DNA binding protein called Histones, the DNA double helix forms a compact DNA: protein complex called chromatin. The chromatin itself is further compacted into higher-order...

Area of Science:

  • Computer Science
  • Psychology
  • Scientific Visualization

Background:

  • Existing Python stimulus software often lacks robust 3D graphics capabilities.
  • Scientists require intuitive tools for creating and displaying complex 3D stimuli in research.

Purpose of the Study:

  • To introduce Ratcave, a novel Python 3D graphics library.
  • To provide an accessible interface for scientists to load, display, and transform 3D stimuli.
  • To enable hardware-accelerated dynamic stimuli creation within existing experimental frameworks.

Main Methods:

  • Developed Ratcave as a free, open-source Python 3 library.
  • Implemented intuitive 3D graphics engine concepts (Mesh, Scene, Light, Camera classes).
  • Utilized modern OpenGL constructs for efficient, hardware-accelerated rendering.

Main Results:

  • Ratcave extends existing Python psychology stimulus software.
  • Offers an interface familiar to users of 2D stimulus libraries.
  • Facilitates the creation of fast, dynamic 3D stimuli.

Conclusions:

  • Ratcave simplifies 3D programming for scientists.
  • It integrates seamlessly with existing Python stimulus libraries.
  • The library enhances the scientific open-source software ecosystem.
