Abstract [en]

Spatial disorientation (SD) has been cited as the leading cause of 33% of all aircraft’s incidents with a fatality rate of almost 100% (Gibb, Ercoline, & Scharff, 2011). In spite of these figures, data from 1947 to 2010 presented by the Aerospace Medical Association indicated that SD’s roles in mishaps over the years are consistent and rates are not declining. Thus, research and training are paramount factors to improve awareness and reduce the probability of SD-related accidents. The failure in recognizing the multisensory aspect of SD is seen by the US Naval Aviation Safety Office as a leading cause of aircraft mishaps from 1990 to 2008. This study examined the effects of vestibular stimulation on cognitive processing. Twenty-four subjects performed spatial and verbal cognitive tasks in a Bárány Chair. Participants had higher throughput scores in spatial tasks than in verbal tasks. No significant difference was observed during acceleration or deceleration phases in both tasks.

Abstract [sv]

Spatial desorientering (SD) har nämnts som den ledande orsaken (33 %) till farliga incidenter i flygning och leder nästan alltid till dödliga utfall (Gibb, Ercoline, & Scharff, 2011). Trots dessa siffror, data från 1947 till 2010 presenteras av Aerospace Medical Association visar att SD: s roller i missöden över år är stabilt och nivåerna minskar inte. Således, forskning och utbildning är avgörande faktorer till öka medvetenheten och minska sannolikheten för SD relaterade olyckor. Misslyckandet att erkänna multisensorisk aspekt av SD ses av US Naval Aviation Safety Office som en ledande orsak till flygplan missöden från 1990 till 2008. Denna studie undersökte effekterna av vestibular stimulering på kognitiv bearbetning. Tjugofyra försökspersoner utförde spatiala-och verbala kognitiva uppgifter i en Bárány stol. Deltagarna hade högre kognitivgenomströmning poäng i spatiala uppgifter än i verbala uppgifter. Ingen signifikant skillnad observerades under acceleration eller inbromsning faser i båda uppgifterna.
