- lots of texture perception work on texture discrimination |
997 |
|
|
998 |
|
- we need also memorization; therefore, careful evaluation is needed |

- experiments on abstract images and photographs |

|
1002 |
|
- pilot test: 15 textures or pure colors shown sequentially, 5 seconds each. |
1003 |
|
recognition tested by showing the 15 seen textures mixed with 15 new |
1004 |
|
textures in a random order. subjects answers old/new. |
1005 |
|
|
1006 |
|
- results: for textures, 80 percent correct (12/15 correctly recognized |
1007 |
|
as seen and 12/15 correctly identified as not seen). |
1008 |
|
for pure colors, 53 percent correct (13/15 correctly recognized |
1009 |
|
as seen and 3/15 correctly identified as not seen). |
