Researchers today can use technology such as fMRI scans to measure brain activity. Some researchers ask their subjects to describe elements of their experiences (e. g., sensations, images, feelings) while undergoing the scans. This technique is similar to the methodology of .
introspection; Titchener T/F

True

Explanation:

The technique used by researchers to ask subjects to describe element of their experience is the introspection technique. The introspection involves the process by which an individual examines his own conscious emotions and thoughts by deeply looking inwards.

The introspection technique is similar to the methodology of Titchener. Titchener studied how the mind worked  and also the different components of consciousness; he made use of introspective techniques and analysis to determine this.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
