1.2 Explain the concepts of threshold and adaptation.
Content Standard 2: The capabilities and limitations of sensory processes
2.1 List forms of physical energy for which humans and non-human animals do and do not have sensory receptors.
2.2 Describe the visual sensory system.
2.3 Describe the auditory sensory system.
2.4 Describe other sensory systems, such as olfaction, gustation, and somesthesis (e.g., skin senses, kinesthesis, and vestibular sense).
Content Standard 3: Interaction of the person and the environment in determining perception
3.1 Explain Gestalt principles of perception.
3.2 Describe binocular and monocular depth cues.
3.3 Describe the importance of perceptual consistencies.

Top Down Processing

Aoccdrnig to rscheearch at Cmabrigde Uinervtisy, it deosn’t mttaer in what order the ltteers in a word are, the only iprmoetnt thing is that the frist and lsat ltteer be at the rghit pclae. The rset can be a total mses and you can still raed it wouthit a porbelm. This is bcuseae the human mind deos not raed ervey lteter by istlef, but the word as a wlohe.

Psychic Card trick



Stare at the red dot on this woman's nose for thirty seconds. Then, look over at a blank white space (a piece of paper or an empty browser tab will do). Did you see the "correct" version of the image? Here's how it works: stare long enough at an object and the eye's photoreceptors (particularly the color-sensitive cone cells) lose sensitivity from overstimulation. Divert the eyes to a blank space, and the surrounding cone cells send out a much stronger signal. The brain interprets this discrepancy as looking at the precise opposite colors, in what is known as a 'negative afterimage.' Nifty, no?
