Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

95.4K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Generalization, Discrimination, and Extinction

1.5K
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Equation of Motion: General Plane motion

591
In the context of a rigid body's movement within a general plane, it is important to understand that this motion is typically triggered by external forces or couple moments exerted onto it. This principle can be explained through Newton's second law, which stipulates the translational motion of the body's center of mass along each axis.
Moreover, the body's center of mass experiences a rotational effect as a result of these couple moments. This rotation can be articulated as the...

Visualize a drone, with its propellers spinning rapidly, hovering mid-air. The fascinating movements and operations of this drone can be comprehended by applying the principle of general plane motion.
As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the...

Consider a lawn roller with a mass of 100 kg, a radius of 0.2 meters, and a radius of gyration of 0.15 meters. A force of 200 N is applied to this roller, angled at 60 degrees from the horizontal plane. What will be the angular acceleration of the lawn roller?
The friction between the roller and the ground is characterized by two coefficients. The static friction coefficient is 0.15, while the kinetic friction coefficient is 0.1. These values are crucial in understanding the interaction between...

Projectile Motion: Example

13.8K
The theory of projectile motion is very useful for players of several sports to improve their performance. For example, a javelin thrower needs to throw their javelin in such a way that it travels as far as possible. The javelin thrower takes a short run-up to increase the initial speed of the javelin. The range of a projectile is at its maximum at a 45° angle so javelin throwers try to angle their throw as close to 45° as possible.
When we speak of the range (R) of a projectile on...

Area of Science:

  • Neuroscience
  • Computational Neuroscience
  • Visual Perception

Background:

  • Spatial context significantly impacts visual processing, modulating the perception of central stimuli.
  • Center-surround interactions are crucial for motion direction perception, particularly involving the middle temporal (MT) area.

Purpose of the Study:

  • To investigate how spatial separation affects center-surround inhibition and motion direction interactions in human subjects.
  • To quantify changes in surround inhibition strength and tuning width with varying spatial distances.

Main Methods:

  • Conducted psychophysics experiments with human participants to measure center-surround motion repulsion effects.
  • Employed a physiological model to extract population parameters of surround inhibition and tuning widths based on spatial distance.

Main Results:

  • Clear motion repulsion effects were observed in most subjects under both near- and far-surround conditions.
  • Surround inhibition was significantly stronger, and tuning widths were smaller under the near-surround condition compared to the far-surround condition.
  • The physiological model accurately predicted human performance.

Conclusions:

  • Spatial separation dynamically modulates surround inhibition strength and the width of surround-to-center tuning.
  • These findings provide insights into the spatial dynamics of neural processing in the visual system, specifically within the MT area.
