The Screw You Effect

A form of experimental sabotage where the research participant does not want to conform to the experiments' demands. When a participant is in an experiment you may not get accurate results because they are aware of the experiment and in turn go out of their way to do everything wrong or go against everything you ask them to, in essence, they may deliberately try to ruin the experiment (the "screw you effect"; Masling 1966).

In Psychology, demand characteristics refers to when a person changes his/her behaviour because he/she is in an unfamiliar situation, carrying out artificial tasks and tries to make sense of this by 'working out' what the researcher wants. After 'working out' what the researcher wants, he/she will either try to 'please' the researcher by doing what he/she thinks the researcher wants them to do (known as the please you effect) or go against what the researcher wants by doing the opposite of what he/she thinks the researcher wants them to do (known as the 'screw you' effect).

For example, the children in Bandura's (1966) study of TV violence and aggression may have punched and kicked 'bobo dolls' because they thought that the study was a 'game' and that this was what Bandura wanted them to do (please you effect), rather than because they'd previously watched an adult punching and kicking the dolls on a video, as Bandura argued (i.e. it wasn't the video that caused the aggression but the expectations of Bandura).

I'll see you when I get my new glasses...

Have a look.

 

The Explanation: 

 

Inattentional blindness, a phenomenon known as "the failure to notice an unexpected stimulus that is in one’s field of vision when other attention-demanding tasks are being performed." This phenomenon is classified as a psychological attentional error - and you'll be relieved to know -  not the result of visionary deficits. The main reason for this lack of attention is the overload of stimuli surrounding us; in order to be able to focus on the intended things, we learn to disregard many others and be unaware of the unattended stimuli. There have been a large number of experiments demonstrating that this phenomenon has a significant effect on people’s perception...and now this one with you.
