Stereotype Content Model02:16

Stereotype Content Model

13.1K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Non-equilibrium in the Cell

4.0K
An important concept in studying metabolism and energy is that of chemical equilibrium. Most chemical reactions are reversible. They can proceed in both directions, releasing energy into their environment in one direction, and absorbing it from the environment in the other direction. The same is true for the chemical reactions involved in cell metabolism, such as the breaking down and building up of proteins into and from individual amino acids, respectively. Reactants within a closed system...

Three-Dimensional Force System:Problem Solving

1.5K
A three-dimensional force system refers to a scenario in which three forces act simultaneously in three different directions. This type of problem is commonly encountered in physics and engineering, where it is necessary to calculate the resultant force on the system, which can then be used to predict or analyze the behavior of the object or structure under consideration.
To solve a three-dimensional force system, first resolve each force into its respective scalar components. Do this using...

Mechanical Efficiency of Real Machines01:14

Mechanical Efficiency of Real Machines

1.6K
The mechanical efficiency of a machine is a fundamental concept that describes how effectively a machine can convert input work into output work. According to this concept, the efficiency of a machine is equal to the ratio of the output work to the input work. An ideal machine, meaning a machine that has no energy losses, has an efficiency of one. This implies that the input work and the output work are equal.
However, in reality, no machine can be truly ideal, and all of them experience some...

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...

Area of Science:

  • Neuroscience
  • Human Motor Control
  • Biomechanics

Background:

  • The thumb's critical role in hand function is well-established.
  • Proprioceptive abilities of the thumb, especially during dynamic movements, are not fully understood.

Purpose of the Study:

  • To quantify dynamic thumb localization ability in unimpaired individuals.
  • To investigate the reference frame used for thumb proprioception and compare it with the index finger.

Main Methods:

  • A novel robotic task measured dynamic thumb localization accuracy.
  • Varied thumb speed, rotation diameter, and introduced propriovisual perturbations.
  • Compared thumb and index finger localization performance.

Main Results:

  • Thumb localization error averaged ~25° and was unaffected by speed or diameter.
  • Adaptation to rotational perturbations suggested a body-centered reference frame.
  • Thumb localization error was significantly larger than the index finger (p = 0.02).

Conclusions:

  • Dynamic thumb localization is less accurate than the index finger.
  • The thumb utilizes visual feedback and a body-centered frame for movement adaptation.
  • Proprioceptive abilities of the thumb and index finger are correlated but distinct.
