Thus we assume that the circles (right) are complete but particularly blocked by the (illusory) triangle. Add nothing more than little line segments that close off the circles and now your brain stops constructing a triangle. Usually, these grouping principles help us construct reality. ]]> 2017-12-05 14:08:27 UTC https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213286793 sarahlagasse1212 https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213288634 Enables us to estimate their distance from us.

To a driver, distant pedestrians appear smaller, which also means that smaller-looking pedestrians (children) may sometimes be misperceived as more distant than they are(Stewart, 2000).]]> 2017-12-05 14:28:56 UTC https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213299069 sarahlagasse1212 https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213300843 If one object partially blocks our view of another, we perceive it as closer.

Because we perceive the lower part of a figure-ground illustration as closer, we perceive it as figure (Vecera &a others, 2002). Invert the illustration below(right) and the black becomes ground, like a night sky. Relative height may contribute to the illusionthat  vertical dimensions are longer than identical horizontal dimensions.]]> 2017-12-05 14:38:44 UTC https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213304621 sarahlagasse1212 https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213306578 As we move, objects that are actually stable may appear to move. If while riding on a his you fix your gaze on some object -sat, a house- the objects closer than the house (the fixation point) appear to move backward. The nearer the object is to you, the faster it seems to move. ]]> 2017-12-05 14:42:11 UTC https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213306578 sarahlagasse1212 https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213308112 Parallel lines, such as railroad tracks, appear to converge with distance. The more the lines converge, the greater their perceived distance. Linear perspective can contribute to rail-crossing accidents by leading people to overestimate a train's distance. ]]> 2017-12-05 14:44:51 UTC https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213308112 sarahlagasse1212 https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213309652 Nearby objects reflect more light to our eyes. Given two identical objects, the dimmer one seems farther away.

The two red bars cast identical-sized images on our retinas. But experience tells us that a more distan object can create the same-sized image as a nearer one only if it is actually larger. As a result,we perceive the bar that seems farther away as larger. ]]> 2017-12-05 14:53:15 UTC https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213313415 sarahlagasse1212 https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213313586 Richard L. Gregory suggested that the corners in our rectangularly carpentered world teach us to interpret "outward" or "inward" pointing arrowheads at the ends of a line as a cue to the lines distance from us and so it's length. The red line defined by the corner at the ticket booth looks shorten than the red line defined by the room corner. But if you measure them, you will see that both are the same length. ]]> 2017-12-05 14:53:32 UTC https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213313586 sarahlagasse1212 https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213314024 The amount of light an object reflects relative to its surroundings. If you view sunlit black paper through a narrow tube so nothing else is visible, it may look gray, because in bright sunshine it reflects a fair amount of light. Veiw it without the tube and it is again black, because it reflects much less light than the objects around it. ]]> 2017-12-05 14:54:07 UTC https://padlet.com/sarahlagasse1212/4mz2ecrg0t5r/wish/213314024
