Abstract
Maģistra darbs uzrakstīts latviešu valodā uz 42 lapām. Tās satur 22 attēlus, 7 tabulus, 30 literatūras avotu atsauksmes.
Darba problēma: noteikt, kā kontūru pamanīšana ar un bez atmiņas slodzes tiek ietekmēta dienas laikā.
Darba mērķis: izpētīt kontūru pamanīšanu atkarībā no dienas laika, uzdevuma ar un bez atmiņas iesaistīšanas un kontūru randomizācijas pakāpes.
Dalībnieki: eksperimentā piedalījās 9 dalībnieki vecumā no 24 līdz 39 gadi. Redzes asums tuvumā 0.8-1.0, pazemināta redzes asuma gadījumā subjekti pildīja eksperimentu ar ierasto korekciju.
Rezultāti un secinājumi: vizuālais nogurums neietekmē kontūru pamanīšanu dienas laikā. Kontūru pamanīšana ar atmiņas iesaistīšanu ir nozīmīgi zemāka nekā eksperimentā bez atmiņas slodzes.
Atslēgvardi: vizuālais nogurums, kontūru pamanīšana, pamanīšanas slieksnis.
The present Master thesis is written in Latvian langueage on 42 pages. It contains 22 pictures, 7 charts, 30 references. Problem: how the contour detection task with and wothout memory workload is influenced during the day. Purpose: to study contour detection during the day, with and without tasks involving memory and levels of stimulus randomization. Subjects: 9 subjects participated in the experiments (from ages 24 to 39). Visual acuity 0.8-1.0, subjects with reduced visual acuity conducted the experiments with usual correction. Results and conclusion: no significant visual fatigue influence on the contour detection during the day was detected. The contour detection was significantly lower in eksperiments with memory load. Keywords: visual fatigue, contour detection, detection threshold.
