Naturalistic Observations02:30

Naturalistic Observations

17.1K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

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,...

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....

Gene-Environment Interactions01:20

Gene-Environment Interactions

1.2K
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Human Factors Engineering

Background:

  • Visual attention is crucial for performance in various professional settings, including surveillance, inspection, and driving.
  • The effectiveness of training visual attention in real-world, distracting environments requires further investigation.
  • Understanding optimal training schedules and the impact of stress is essential for maximizing attentional performance.

Purpose of the Study:

  • To evaluate the efficiency of training visual attention in central and peripheral visual fields.
  • To determine the minimum training repetitions for peak performance and compare intra-day versus inter-day training.
  • To assess whether demanding tasks, like microsurgery, negate training effects and if stress exposure influences training outcomes.

Main Methods:

  • A visual detection task was employed in a naturalistic setting with dynamic visual distractors.
  • The study investigated the number of training repetitions needed for optimal performance.
  • Training protocols were compared before and after exposure to a stressful task (microsurgical intervention).

Main Results:

  • Attentional performance peaked within 3 days for central visual field tasks and 7 days for peripheral tasks.
  • Intra-day training showed no significant performance improvement.
  • Training administered after stress exposure resulted in more pronounced improvements in attentional performance compared to pre-stress training.

Conclusions:

  • Visual attention can be trained effectively within a short timeframe (3-7 days) in realistic work environments.
  • Training visual attention *in situ* (at the workplace) is recommended for enhanced efficacy.
  • Stress exposure may enhance the benefits of subsequent attention training, suggesting a potential for optimized training protocols in high-pressure professions.
