Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

95.0K
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...

Perceptual Constancy01:12

Perceptual Constancy

1.3K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Generalization, Discrimination, and Extinction01:24

Generalization, Discrimination, and Extinction

1.4K
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...

Reducing Line Loss01:18

Reducing Line Loss

372
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

Methods of reducing fever01:22

Methods of reducing fever

1.3K
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Drug Dosing: Infants and Children

267
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Summary

This study shows that a perceptual discrimination training task effectively reduces fear overgeneralization in children. The training improved their ability to distinguish between threat and safety cues, decreasing fear responses.

Area of Science:

  • Psychology
  • Neuroscience
  • Child Development

Background:

  • Excessive fear generalization can be maladaptive, impacting emotional regulation.
  • Perceptual discrimination training aims to mitigate this overgeneralization.
  • Understanding these mechanisms is crucial for developing targeted interventions.

Purpose of the Study:

  • To evaluate the efficacy of a perceptual discrimination training task in reducing fear overgeneralization in typically developing children.
  • To compare the training's effects against placebo and no-task control conditions.

Main Methods:

  • Seventy-three children were randomly assigned to a training, placebo, or control group.
  • Participants underwent differential fear conditioning, followed by the discrimination training or placebo task.
  • Fear generalization was assessed using physiological and self-report measures.

Main Results:

  • Fear conditioning was successfully established across physiological and self-report measures.
  • The training group demonstrated superior perceptual discrimination compared to the placebo group.
  • Physiological data indicated significantly less fear overgeneralization in the training group versus controls.

Conclusions:

  • The perceptual discrimination training task effectively moderates fear overgeneralization in children.
  • These findings extend previous research demonstrating the task's effectiveness in adults.
  • This training offers a promising avenue for managing exaggerated fear responses in pediatric populations.
