Thermosensation01:43

Thermosensation

30.5K
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...

Factors Affecting Perception01:25

Factors Affecting Perception

1.7K
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...

Synesthesia01:27

Synesthesia

165
Synesthesia is a remarkable condition where stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. People with synesthesia experience a blending or crossing of their senses, such as sight and sound, leading to cross-modal sensations. In this condition, the stimulation of one sense, such as hearing a number or musical note, triggers an experience of another sense, like sensing a specific color, taste, or smell. People...

Mechanisms of Heat Transfer II01:20

Mechanisms of Heat Transfer II

3.3K
In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...

Assessing Body Temperature - Temporal Artery

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...

Temperature and Thermal Equilibrium01:11

Temperature and Thermal Equilibrium

6.9K
Heat and temperature are essential concepts for everyone every day. The study of heat and temperature is part of an area of physics known as thermodynamics. It is not always easy to distinguish heat and temperature.
The concept of temperature has evolved from the common concepts of hot and cold. The scientific definition of temperature explains more than just our sense of hot and cold. Temperature is operationally defined as the quantity measured with a thermometer. Furthermore, temperature is...

Summary

Crossmodal correspondences between visual textures and temperature were explored. Semantic learning, linking textures to temperature concepts, had a stronger influence than affective learning, suggesting a greater role for semantic pathways.

Area of Science:

  • Cognitive Psychology
  • Crossmodal Perception
  • Sensory Science

Background:

  • Crossmodal correspondences, particularly those involving temperature, are of increasing interest.
  • However, the specific mechanisms driving these temperature-related associations remain underexplored.

Purpose of the Study:

  • To investigate the roles of affective and semantic pathways in crossmodal associations between visual textures and temperature concepts.
  • To determine the relative influence of affective versus semantic learning on these associations.

Main Methods:

  • Utilized an associative learning paradigm with two online experiments.
  • Employed visual textures with and without prior thermal effusivity associations.
  • Participants completed speeded categorization tasks before and after learning texture-stimulus mappings (affective or semantic).

Main Results:

  • Both affective and semantic learning influenced the categorization of visual textures with temperature concepts.
  • The impact of semantic learning was significantly larger than that of affective learning across both experiments.
  • No significant influence on reaction times was observed.

Conclusions:

  • Semantic pathways play a more dominant role than affective mechanisms in forming crossmodal associations between visual textures and temperature.
  • These crossmodal associations can be modulated through associative learning, establishing correlations with affective or semantic stimuli.
