The kittens had abnormally small ocular dominance columns (part of the brain that processes sight) connected to the closed eye, and abnormally large, wide columns connected to the open eye. Because the critical period time had elapsed, it would be impossible for the kittens to alter and develop vision in the closed eye.
The Life Events and Difficulties Schedule is a psychological measurement of the stressfulness of life events. It was created by psychologists George Brown and Tirril Harris in 1978. [ 1 ] Instead of accumulating the stressfulness of different events, as was done in the Social Readjustment Rating Scale by Thomas Holmes and Richard Rahe, they ...
Chronobiology comes from the ancient Greek χρόνος (chrónos, meaning "time"), and biology, which pertains to the study, or science, of life. The related terms chronomics and chronome have been used in some cases to describe either the molecular mechanisms involved in chronobiological phenomena or the more quantitative aspects of ...
Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. Homeostasis: regulation of the internal environment to maintain a constant state; for example, sweating to reduce temperature
Pivotal response treatment is a naturalistic intervention model derived from the principles of applied behavior analysis.Rather than target individual behaviors one at a time, PRT targets pivotal areas of a child's development such as motivation, [3] responsiveness to multiple cues, [4] self-management, and social initiations.

The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
Glen Elder theorized the life course as based on five key principles: life-span development, human agency, historical time and geographic place, timing of decisions, and linked lives. As a concept, a life course is defined as "a sequence of socially defined events and roles that the individual enacts over time" (Giele and Elder 1998, p. 22).
Kuhn challenged the conventional view in the philosophy of science at the time that knowledge growth could be understood entirely as a process of gradual, cumulative growth. [12] Stephen Jay Gould writes that "Thomas Kuhn’s theory of scientific revolutions" was "the most overt and influential" scholarly work to make a "general critique of ...
