Observational Studies

11.1K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Naturalistic Observations

17.4K
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...

The Thyroid Gland01:23

The Thyroid Gland

7.7K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Velocity of an Object01:18

Velocity of an Object

207
Understanding how an object moves along a path requires distinguishing between motion over a time span and motion at a precise moment. A useful example is a vehicle traveling along a straight and level path, where its position at any given time is known. The initial step in analyzing this motion is to measure how far the vehicle travels over a fixed time period. This measurement, called average velocity, is computed by dividing the total change in position by the duration over which the change...

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

5.6K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Potential Due to a Polarized Object01:29

Potential Due to a Polarized Object

788
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

Area of Science:

  • Ophthalmology
  • Psychology
  • Medical Imaging

Background:

  • Thyroid-associated orbitopathy (TAO) can cause significant facial disfigurement.
  • Understanding how these facial changes affect social perception is crucial.

Purpose of the Study:

  • To quantify the attentional distraction caused by facial deformities in severe TAO.
  • To investigate how observers' gaze patterns differ when viewing patients with and without TAO.

Main Methods:

  • Utilized 3D facial images of patients with severe TAO and controls.
  • Employed eye-tracking technology to record observer eye movements and fixations.
  • Applied multivariate statistical analysis to compare attention distribution across facial regions.

Main Results:

  • Observers showed significantly different attention distribution between TAO and control faces.
  • Attention was significantly increased towards the eyes in severe TAO patients.
  • Attention was significantly decreased towards the nose in severe TAO patients, with no significant differences for the mouth or other facial areas.

Conclusions:

  • Severe TAO redirects observer attention, particularly towards the eyes.
  • These findings provide insight into how TAO impacts social perception.
  • Further research should explore the link between altered gaze patterns and social perception in TAO patients.
