Sustainable Development

15.1K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Design Example: Sustainability in Concrete Building

416
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

978
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....

Visual System01:26

Visual System

1.8K
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Visual Agnosia01:12

Visual Agnosia

1.1K
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

9.2K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Area of Science:

  • Developmental psychology
  • Cognitive neuroscience
  • Motor control

Background:

  • Sustained visual attention is crucial for development.
  • Its development is typically seen as enhanced internal control.
  • The role of sensory-motor skills is often overlooked.

Purpose of the Study:

  • To investigate the link between sensory-motor coordination and visual attention in toddlers.
  • To determine if manual behavior influences eye gaze duration and patterns during object interaction.
  • To explore the underlying mechanisms of visual attention development.

Main Methods:

  • Toddlers played with toys manipulated for weight (heavy vs. light).
  • Manual behavior (ease of manipulation) was the independent variable.
  • Eye gaze patterns (duration, frequency of glances) were the dependent variables.

Main Results:

  • Visual attention was tightly coupled with manual activity duration.
  • Toddlers with heavy toys had shorter, more frequent glances.
  • Toddlers with light toys exhibited longer, sustained visual attention.
  • These effects were independent of general interest in the objects.

Conclusions:

  • Sustained visual attention in toddlers emerges from sensory-motor coordination, not just cognitive control.
  • Hand-eye coordination significantly impacts the duration and nature of visual attention.
  • This finding offers a new perspective on the developmental trajectory of visual attention.
