Individual differences in the ability to discriminate the direction of spontaneous changes in peripheral finger
Abstract:
Spontaneous fluctuations of .1 degrees C in peripheral finger temperature were recorded for a 30-minute baseline period in 10 subjects. Those meeting specified criteria of temperature fluctuations were then asked to judge the direction of change in computer-detected temperature fluctuations of .1 degrees C, first without feedback, then with feedback (knowledge of results). Only 1 subject produced convincing evidence of ability to make directional judgments at better than chance level, though more training with feedback might have benefited other subjects. The theoretical significance of these results for the relationship between discrimination and voluntary control is discussed.

Equipments Used to Measure Body Temperature
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...
Assessing Body Temperature - Temporal Artery
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 forehead...
