Zásady pro vypracování |
Stručné vymezení práce a zásady pro její vypracování:
Diplomová práce je založena na empirické studii provedené v rámci širšího projektu "Vliv čichové stimulace na afektivní ladění snů a afektivní vyladění po probuzení" (GAČR 17-14534S). Studující zpracuje teoretickou část práce s využitím relevantní literatury (výběr viz níže). Přibližná struktura teoretické části (osnova): 1) Definice snů (resp. mentální aktivity ve spánku), specifika REM a NREM snů 2) Vliv snů na psychologický i fyzický well-being člověka 3) Možnosti experimentálního ovlivnění snů - důraz na čichovou stimulaci a předpoklady jejího uplatnění 4) Dosavadní evidence dokládající, že pachy mohou ovlivňovat mentální aktivitu ve spánku - důraz na sny a vliv příjemnosti pachů V rámci empirické části práce studující zanalyzuje data, která vzešla z výše uvedeného projektu. Testovat bude hypotézu, že dobrovolníci, kteří hodnotili pach jako příjemnější, uváděli příjemnější REM sny. Svá zjištění bude diskutovat v kontextu dosavadních poznatků o vlivu pachů na spánek a snění. |

Previous laboratory research has shown that exposure to odours of contrasting general pleasantness during sleep differentially affects the emotional tone of dreams. However, it is not clear how individually rated odour pleasantness influences dream valence, and specifically that of REM dreams, which tend to yield higher dream recall and more perceptually vivid and emotionally charged dream reports than those from the non-REM (NREM) stages. Hence, in the present study, in a sleep laboratory we exposed in a randomised order 60 healthy volunteers to (1) either a generally pleasant (vanillin) or generally unpleasant (thioglycolic acid) odour and, on another night, (2) an odourless control condition. The participants were always woken up 5 minutes into the first REM that occurred after 4 a.m. and if they reported they had been dreaming, they were asked to rate the pleasantness of that dream. They also rated the ambient odour, if they could perceive any. We expected that for both the generally pleasant and generally unpleasant odour, higher pleasantness ratings would be associated with greater REM dream pleasantness. |
