Introduction to Cognitive Psychology01:20

Introduction to Cognitive Psychology

2.7K
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...

Automatic Processing and Automatic Social Behavior01:28

Automatic Processing and Automatic Social Behavior

376
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Hierarchy of Motor Control01:18

Hierarchy of Motor Control

5.6K
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.

Drive-Reduction Theory: Push Theory of Motivation

1.8K
Clark Hull's drive-reduction theory, introduced in the 1940s and 1950s and often termed the "push theory" of motivation, provides a framework for understanding how biological and learned drives influence behavior. Hull suggested that motivation originates from the need to alleviate physiological tension caused by unmet biological necessities. The theory proposes that when a basic need, such as hunger or sleep, goes unfulfilled, it creates an internal imbalance. This imbalance, or...

Cognitive Learning01:21

Cognitive Learning

1.6K
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

High-Level and Low-Level Awareness01:19

High-Level and Low-Level Awareness

989
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Area of Science:

  • Cognitive Neuroscience
  • Evolutionary Biology
  • Neuroanatomy

Background:

  • Human cognition is characterized by the ability to delegate control of repetitive tasks to lower neural centers.
  • The evolution of bipedality in proto-humans presented significant neurocomputational challenges.
  • Efficient task delegation may have conferred a selective advantage during human evolution.

Purpose of the Study:

  • To explore the hypothesis that the shift to bipedal locomotion drove the evolution of human neuronal functioning.
  • To review functional neuroanatomy studies relevant to this hypothesis.
  • To identify future research directions for testing this idea.

Main Methods:

  • Review of recent functional neuroanatomy studies.
  • Analysis of the neurocomputational demands of bipedalism.
  • Hypothesis formulation based on evolutionary and cognitive principles.

Main Results:

  • The transition to bipedality likely necessitated and rewarded the development of efficient neural task delegation.
  • This evolutionary pressure may have shaped distinctive features of human brain function.
  • Functional neuroanatomy provides evidence supporting the link between locomotion and cognitive evolution.

Conclusions:

  • The evolution of bipedalism is a plausible driver for the development of advanced cognitive abilities in humans.
  • Neural delegation of tasks is a key innovation in human cognition.
  • Further research in functional neuroanatomy is needed to validate these evolutionary links.
