Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

969
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

COPD: Pathogenesis and Clinical Features01:20

COPD: Pathogenesis and Clinical Features

1.8K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Chromatin Position Affects Gene Expression02:35

Chromatin Position Affects Gene Expression

24.8K
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences  access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area. 
Topologically Associated Domains (TADs)
The 3-dimensional positioning of chromatin in the nucleus influences the...

Special Features of Adaptive Immunity01:20

Special Features of Adaptive Immunity

3.3K
The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.0K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

What is Gene Expression?01:42

What is Gene Expression?

196.6K
Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Social Psychology

Background:

  • Facial expressions are crucial for social interaction, signaling helpfulness or harm.
  • Facial emotion perception is complex, often influenced by ambiguous expressions and other cues like race, sex, and context.

Purpose of the Study:

  • To investigate how reducing different types of uncertainty affects facial emotion categorization.
  • To explore the interaction between feature-based attention to emotion and spatially selective attention.

Main Methods:

  • Participants categorized facial emotions presented peripherally.
  • Uncertainty was manipulated by providing cues about the face's location, emotion, or both, versus no information.

Main Results:

  • Cueing emotion or location sped up response times compared to no cue.
  • Cueing emotion alone was faster than cueing location alone.
  • Cueing both location and emotion showed a superadditive benefit, indicating interaction between spatial and feature-based attention.
  • Reducing uncertainty about facial expression eliminated reliance on stable identity cues (sex, race) for emotion interpretation.

Conclusions:

  • Feature-based attention to facial expression and spatially selective attention interact to enhance face perception.
  • Predictive cueing of facial emotion significantly reduces the need for stable identity cues in emotion categorization.
