The questions are simple enough, but the answers are surprisingly difficult. The Sensory Absolute Threshold: It is the smallest detectable limit of a sensory stimulus. Absolute threshold is the smallest level of energy required by an external stimulus to be detectable by the human senses, including vision, hearing, taste, smell and touch So absolute threshold for taste is a teaspoon of sugar in one gallon of water. Clearly, it is advantageous for the taste system to detect potentially dangerous substances (e.g., bitter-tasting plant compounds) at much lower concentrations. Psychology Ch 3-Final 64 terms. is the smallest amount of energy needed for a person to detect a stimulus 50% of the time. Rats and dogs have a 2.5 log unit lower absolute odor detection threshold than humans. It is more precisely defined as the degree of intensity of a stimulus necessary to correctly detect that stimulus 50% of the time. Hearing – A watch ticking 20 ft away. Each sense has its own level of absolute threshold, and for each person it can vary. The sensitivity of a given sensory system to the relevant stimuli can be expressed as an absolute threshold. Gustav Fechner. The difference threshold applies to all of our areas of perception, including the 5 human senses, sight, smell taste, hearing, and touch.
