~Yes subliminal messaging is real 
~They have been used in ads in the past. In the middle of a movie, there would be words that appeared for a single frame, long enough for the subconscious to pick up, but too short for the viewer to be aware of it.
~This is not actually illegal, it is just the country's advertising and broadcasting regulatory agencies that deal with the topic and its impact on the public
~This could cause problems in society because it could give power to the people that use this process to gain control or influence people.

Websters Law- also called Weber-Fechner law, historically important psychological law quantifying the perception of change in a given stimulus. The law states that the change in a stimulus that will be just noticeable is a constant ratio of the original stimulus.]]> 2016-10-20 15:10:29 UTC https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132103070 Signal detection theory zarahfowler https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132106129  provides a precise language and graphic notation for analyzing decision making in the presence of uncertainty. The general approach of signal detection theory has direct application for us in terms of sensory experiments. But it also offers a way to analyze many different kinds of decision problems.
It says the absolute threshold ins't the same for everyone. ]]> 2016-10-20 15:17:21 UTC https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132106129 Hearing zarahfowler https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132115678 2016-10-20 15:40:05 UTC https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132115678 Priming  meredithhollinger https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132115684 ~Priming is a nonconscious form of human memory concerned with perceptual identification of words and objects.
~An example would be a person who sees the word "yellow" will be slightly faster to recognize the word "banana." This happens because yellow and banana are closely associated in memory]]> 2016-10-20 15:40:06 UTC https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132115684 Vision zarahfowler https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132117442 2016-10-20 15:43:40 UTC https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132117442 Smell  zarahfowler https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132117915 2016-10-20 15:44:43 UTC https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132117915 taste zarahfowler https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132118476 2016-10-20 15:46:04 UTC https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132118476 touch zarahfowler https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132118903 2016-10-20 15:47:10 UTC https://padlet.com/meredithhollinger/vgayqtz53kwd/wish/132118903
