Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Spatial remapping abilities as obtained through eye-movement characteristics (e.g. endpoint error and onset latency) and behavioural responses of location discrimination (i.e., the ability to accurately judge whether two stimuli were presented at identical locations). All parameters will be assessed for different directions of spatial remapping (see last paragraph of introduction) enabling within-subject analyses. | — |
Secondary
| Measure | Time frame |
|---|---|
| Problems related to spatial remapping deficits encountered in daily life. These answers will be measured with a questionnaire on a 5-point Likertscale. | — |
