Auditiva distraktioners påverkan på prestationen i visuella sökuppgifter – är visuell load en modererande faktor?
(2019) PSYK11 20182Department of Psychology
- Abstract (Swedish)
- I arbetslivet överlag är förekomsten av distraktioner många gånger en problemkälla och begreppet kognitiv ergonomi har på senare tid fått ökat fokus. I det här arbetet undersöktes hur arbetsprestationen under visuella sökuppgifter utifrån auditiva instruktioner påverkades av auditiva (ickeverbala) distraktioner under låg respektive hög load. Load manipulerades genom förekomsten av distraherande visuella stimuli. Resultatet visade att en hög visuell load utan auditiva distraktioner sänkte prestationen medan auditiva distraktioner inte påverkade resultatet. 32 universitetsstudenter rekryterades till en 2x2 faktoriell Repeated Measures design där load (2: låg, hög) och auditivt brus (2: ej brus, brus) utgjorde faktorerna. Experimentet... (More)

Experimentet simulerade en potentiell arbetssituation i form av en visuell sökuppgift på en hemsida utformad efter SEEV (Steelman, McCarley, & Wickens, 2017) och N-SEEV (Steelman, McCarley, & Wickens, 2011) modellerna med instruktioner i hörlurar. Sammanfattningsvis kan detta betyda att visuella stimuli utgör större hot mot den kognitiva ergonomin jämfört med auditiva distraktioner förutsatt att inget språk förekommer samt att användandet av auditiva stimuli kan utgöra en effektiv copingstrategi, detta behöver dock undersökas närmare och individuella skillnader måste vägas in. Uppgiftens load tycks utgöra en modererande faktor även om ytterligare forskning behövs för att beskriva förhållandena mellan olika typer av distraktioner samt huruvida uppgiftens svårighetsgrad styrs av kognitiv eller perceptuell load.

- Abstract
- The occurrence of distractors is often a factor reducing the productivity in workspaces and cognitive ergonomics has gained increased focus. This work investigated how auditory (nonverbal) distractions during low and high load influenced the performance of a visual search task based on auditory instructions. Load was manipulated by the presence of distracting visual stimuli. The result showed that a high visual load without auditory distractions lowered performance while auditory distractions did not affect the result. 32 university students were recruited to a 2x2 factual Repeated Measures design where load (2: low, high) and auditory noise (2: not noise, noise) constituted the factors. The experiment simulated a potential work situation... (More)

The experiment simulated a potential work situation on a website designed according to the SEEV (Steelman et al., 2017) and N-SEEV (Steelman et al., 2011) models with instructions given through headphones. In conclusion, the results indicate that visual stimuli affect cognitive ergonomics negatively compared to auditory distractions, given that it’s non-verbal and that the use of auditory stimuli can constitute an effective coping strategy, however, this needs to be investigated more thoroughly. Task load seems to be a moderating factor, although further research is needed to describe the relationships between different types of distractions and whether the task difficulty is controlled by cognitive or perceptual load.
