Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
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...

Hand hygiene

6.0K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Integration by Parts: Indefinite Integrals

171
Integration by parts is a fundamental technique in calculus for evaluating integrals involving the product of two functions. It is particularly useful when direct integration is not feasible. The method is based on the product rule for differentiation, which states that the derivative of a product equals the derivative of the first function times the second, plus the first function times the derivative of the second. By integrating this identity and rearranging terms, the integration by parts...

Integration by Parts: Definite Integrals

79
Definite integrals involving the product of two functions over a fixed interval can be evaluated using integration by parts. This method rewrites the integral as the difference of a product evaluated at the endpoints and a remaining definite integral that is often simpler to compute.A representative example is the definite integral of the inverse tangent function. Since there is no direct integration formula for arctan ⁡x, the integrand is rewritten as a product of arctan⁡ x and the...

Muscles of the Forearm that Move the Hand and Fingers

2.6K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Area of Science:

  • Paleoanthropology
  • Cognitive Archaeology
  • Neuroscience

Background:

  • Testing cognitive hypotheses in extinct species is challenging.
  • Human parietal cortex specialization is linked to visuospatial integration, crucial for technological and symbolic capacities.
  • Hand-tool relationships involve spatial planning, body cognition, and tool integration into body schemes.

Purpose of the Study:

  • To explore cognitive abilities of extinct human species through archaeological evidence.
  • To investigate the co-evolution of body and technology in human evolution.
  • To evaluate the extent to which complex cognitive resources rely on external technological delegation.

Main Methods:

  • Integration of independent data sources: anatomy, archaeology, neurobiology, psychology.
  • Quantitative and experimental validation of cognitive hypotheses.
  • Analysis of lithic tool shapes and associated grasping patterns.
  • Physiological measures like electrodermal activity to assess cognitive responses to haptic experiences.

Main Results:

  • Lithic tools provide crucial insights into extinct human cognitive abilities.
  • Tool shape and haptic feedback offer quantitative approaches to assess cognitive changes in the archaeological record.
  • Electrodermal activity can differentiate cognitive responses to various tools and subjects.

Conclusions:

  • A co-evolution between body and technology is evident in human evolution, extending beyond anatomical correspondence to cognitive integration.
  • The study of hand-tool interactions offers a window into the cognitive evolution of extinct hominins.
  • Understanding cognitive delegation to external technology is key to comprehending complex human cognition.
