Unit 3A: Perception Part 2 Flashcards
Relative size
We assume that two objects are similar in size, we perceive that one casts the smaller retinal image as farther away
Monocular cues
Distance cues, such as linear perspective and overlap available to either eye alone
Interposition
If one object partially blocked our view of another, we perceive it as closer
Relative clarity
Because light from distant objects passes the more atmosphere, we perceive hazy objects as farther away than shark, clear objects. Such as, fog and judging distance.
Texture gradient
A gradual change from a course, distinct texture to find, indistinct texture signals increasing distance. If a picture goes from distinct to indistinct, that means it is further away
Relative height
We perceive objects in our field of vision as farther away. Relative height may contribute to the illusion that vertical dimensions are longer than identical horizontal dimension.
Relative motion
As we move, objects that are actually stable me appear to move. Objects at different distances change their relative positions in our relative image.
Linear perspective
Parallel lines, such as railroad tracks, appeared to converses distance. The more the lines converge, the greater their perceived distance. Train accidents happen due to this because they seem a greater distance away
Light and shadow
Nearby objects with more light to our eyes. Dimmer object seem further away. Thus, given two identical objects, the dinner one seems farther away. When the fog shrouded vehicle, or one with only its parking lights on, seems farther away than it is it can cause an accident
Motion detection
Our brains ability to detect motion
1) our brain computes motion as objects move across the wetness
2) how our head follows a stimuli
Stroboscopic movement
The illusion of motion that occurs when a stationary object is for seeing briefly in one location and, following a short interval, is seen in another location.
Phi phenomenon
An illusion of movement created when two or more adjacent lights blink on and off in succession.
Auto kinetic effect
When still lights appearto move or twinkle in darkness
Perceptual constancy
Perceiving objects as unchanging (having consistent lightness, color, shape, and size) even as illumination and retinal images change
Size constancy
Our ability to perceive objects as having constant size, even while our distance from them varies. Things do not grow or shrink as they move closer or farther
