Assessing Body Temperature - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

1.2K
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Thermosensation01:43

Thermosensation

34.0K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Assessing Body Temperature - Temporal Artery

1.3K
Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's...

Implicit Personality Theories01:23

Implicit Personality Theories

491
Implicit personality theory explains how individuals make assumptions about the relationships between personality traits, behaviors, and character types. When people learn that someone possesses a particular trait, they tend to infer the presence of other related characteristics, forming a cohesive impression. This cognitive shortcut plays a crucial role in social interactions and interpersonal judgments.Central Traits and Their InfluenceSolomon Asch's seminal 1946 study highlighted the power...

Factors Affecting Perception01:25

Factors Affecting Perception

2.9K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Cerebral Hemispheres01:05

Cerebral Hemispheres

2.6K
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Area of Science:

  • Neuroscience
  • Psychology
  • Physiology

Background:

  • Cerebral asymmetry influences cognitive processes.
  • Hemispheric cognitive style is a known individual difference.
  • Ear temperature as a physiological marker is under-explored.

Purpose of the Study:

  • To investigate the correlation between hemispheric cognitive style and ear temperature.
  • To explore the potential of ear temperature as a noninvasive indicator of cognitive style.

Main Methods:

  • 100 participants completed the Hemispheric Consensus Prediction Profile.
  • Ear temperatures were measured twice per ear across two sessions.
  • Dominant ear temperature was calculated as the difference between right and left ear temperatures.

Main Results:

  • A statistically significant positive correlation (Spearman's ρ =.29) was found between cognitive style scores and ear temperature in 56 participants with stable dominant ear temperature.
  • Individuals with a left hemispheric cognitive style showed warmer left tympanic membrane temperatures.
  • Individuals with a right hemispheric cognitive style showed warmer right tympanic membrane temperatures.

Conclusions:

  • A link exists between hemispheric cognitive style and tympanic membrane temperature.
  • Noninvasive ear temperature measurement may offer insights into cerebral asymmetry.
  • Further research into this relationship could advance the study of brain lateralization.
