Table 1. Mean and standard deviation (in parentheses) measures of response time, in milliseconds, for the Adult and Child groups on the various levels of the Cue (Space, Time), Validity (Valid, Invalid), and Stimulus Onset Asynchrony (SOA) (500ms, 1100ms) independent variables of the spatial and temporal orienting task.
| Space Valid 500ms | Space Invalid 500ms | Validity effect | Space Valid 1100ms | Space Invalid 1100ms | Validity effect | Time Valid 500ms | Time Invalid 500ms | Validity effect | Time Valid 1100ms | Time Invalid 1100ms | Validity effect | |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Adults | 311 (42) | 344 (59) | 33 | 291 (36) | 306 (47) | 15 | 282 (36) | 304 (42) | 22 | 271 (31) | 277 (34) | 6 |
| Children | 381 (79) | 492 (126) | 111 | 350 (61) | 469 (121) | 119 | 372 (67) | 379 (77) | 7 | 339 (57) | 343 (69) | 4 |
The difference between the Invalid and Valid trials per condition is noted as the Validity effect. The small temporal validity effects at 1100ms were expected, and are due to the influence of the variable FP effect on temporal orienting.
