Martin Theodore Orne (October 16, 1927, Vienna, Austria – February 11, 2000, Paoli, Pennsylvania, US) [1] [2] was a professor of psychiatry and psychology at the University of Pennsylvania. Orne is best known for his pioneering research into demand characteristics , illustrating the weakness of informing participants that they are taking part ...
Pioneering research was conducted on demand characteristics by Martin Orne. [2] A possible cause for demand characteristics is participants' expectations that they will somehow be evaluated, leading them to figure out a way to 'beat' the experiment to attain good scores in the alleged evaluation. Rather than giving an honest answer ...
Demand characteristics refer to a type of response bias where participants alter their response or behavior simply because they are part of an experiment. [3] This arises because participants are actively engaged in the experiment, and may try to figure out the purpose, or adopt certain behaviors they believe belong in an experimental setting.
The experimenter may introduce cognitive bias into a study in several ways — in the observer-expectancy effect, the experimenter may subtly communicate their expectations for the outcome of the study to the participants, causing them to alter their behavior to conform to those expectations.
Resource characteristics are those that relate partly to mental and emotional resources such as past experiences, skills, and intelligence, and also to social and material resources (access to good food, housing, caring parents, and educational opportunities appropriate to the needs of the particular society).

[1] [2] The effect was discovered in the context of research conducted at the Hawthorne Western Electric plant; however, some scholars think the descriptions are fictitious.
Becker's subsequent 1962 paper provides an independent justification for neoclassical market demand analysis. The two papers offer separate justifications for the use of neoclassical methodology for supply and demand analysis without relying on assumptions otherwise criticised as implausible.
