|---|---|---|---|---|---|
| show | process in which we detect physical energy from the environment and then encode it as neural signals (sensory receptors and nervous system receive and represent stimulus energies from our environment)
🗑
|
||||
| Perception | show 🗑
|
||||
| show | begins with sensory receptors and works up to brains integration of sensory info
🗑
|
||||
| show | info processing guided by higher level mental processes (when we draw perception from our experience or expectations)
🗑

|
||||
| Absolute threshold | show 🗑
|
||||
| show | below the absolute threshold for conscious awareness
🗑
|
||||
| show | the often unconscious activation of certain associations, predisposing ones perception, memory or response.
🗑
|
||||
| show | the minimum difference between two stimuli required for detection 50% of the time (Just Noticeable Difference)
🗑
|
||||
| show | for stimuli to be perceived as different, they must differ by a constant percent rather than amount
🗑
|
||||
| show | diminished sensitivity as a consequence of constant stimulation
🗑
|
||||
| show | distance from one wave peak to the next
🗑
|
||||
| show | dimensions of color determined by wave length
🗑
|
||||
| show | amount of energy in light waves- determines brightness, determined by wave height
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
