Summary
The hue-heat effect, linking color and temperature perception, was studied. Researchers found light and color can alter perceived warmth, with immediate and delayed effects, paving the way for practical applications.
Area of Science:
- Psychophysics
- Sensory science
- Human-computer interaction
Background:
- The hue-heat effect describes the link between visual perception (color) and thermal sensation.
- While hypothesized, practical applications of the hue-heat effect are limited.
- Understanding this multisensory phenomenon is key for real-world use.
Purpose of the Study:
- To investigate the relationship between perceived temperature and illumination.
- To explore practical applications of the hue-heat effect.
- To quantify the impact of light and color on thermal perception.
Main Methods:
- Conducted a series of psychophysical experiments.
- Utilized a well-controlled experimental environment.
- Investigated the effects of illumination on perceived coolness/warmness.
Main Results:
- Identified three distinct effects of illumination: creating, eliminating, and exchanging.
- Demonstrated that the 'creating' effect is immediate.
- Showed that the 'eliminating' effect has a time delay.
Conclusions:
- Illumination significantly influences perceived temperature through various effects.
- Distinct temporal profiles exist for different hue-heat effects.
- Findings enhance understanding and enable practical applications of the hue-heat effect, potentially aiding energy conservation.

01:25Factors Affecting Perception
2.4K
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.

27.7K
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or the other depending upon the temperature of the substance in question. Likewise, some chemical reactions can also exhibit temperature-dependent spontaneities. To illustrate this concept, the equation relating free energy change to the enthalpy and entropy changes for the process is considered:

01:27Atomic Spectroscopy: Effects of Temperature
765
Atomization, converting samples into gas-phase atoms and ions, is essential for atomic spectroscopy. The flame temperature required for atomization affects the efficiency of the atomic spectroscopic methods by increasing the atomization efficiency and the relative population of the excited and ground states.
At thermal equilibrium, the relative populations of excited and ground state atoms can be estimated using the Maxwell–Boltzmann distribution. For example, an increase in temperature...

33.4K
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...

01:20Mechanisms of Heat Transfer II
4.0K
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...
