Ambiguous images are important to the field of psychology because they are often research tools used in experiments. [3] There is varying evidence on whether ambiguous images can be represented mentally, [4] but a majority of research has theorized that mental images cannot be ambiguous. [5]
As long as the modulation frequency is kept above the fusion threshold, the perceived intensity can be changed by changing the relative periods of light and darkness. One can prolong the dark periods and thus darken the image; therefore the effective and average brightness are equal. This is known as the Talbot-Plateau law. [2]
The Hawthorne effect is a type of human behavior reactivity in which individuals modify an aspect of their behavior in response to their awareness of being observed. [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.
A signature feature of a fluorescent light bulb is the subtle hum or buzz, but if it increases in volume or becomes too much, you'll want to check for a larger problem. The most likely cause is a ...
He says he lost his keys and they both look under the streetlight together. After a few minutes the policeman asks if he is sure he lost them here, and the drunk replies, no, and that he lost them in the park. The policeman asks why he is searching here, and the drunk replies, "this is where the light is". [2] The anecdote is attributed to ...
In a typical Ganzfeld experiment, a "receiver" is placed in a room relaxing in a comfortable chair with halved ping-pong balls over the eyes, having a red light shone on them. The receiver also wears a set of headphones through which white or pink noise (static) is played. The receiver is in this state of mild sensory deprivation for half an hour.
Figure 2: Stroboscopic effect contrast threshold function (see Visibility) All observer-related influence quantities are stochastic parameters, because not all humans perceive the effect of same light ripple in the same way. That is why perception of stroboscopic effect is always expressed with a certain probability.
