Abstract

Teorijski okvir ovog diplomskog rada temeljen je na Hipotezi o ovulatornom pomaku, Teoriji roditeljskog ulaganja i Teoriji upravljanja pogreškama (EMT). EMT sugerira da su ljudska percepcija, donošenje odluka te različite kognitivne pristranosti evoluirali tako da minimiziraju pogreške koje bi mogle imati ozbiljne posljedice po preživljavanje i reprodukciju pojedinca. U ovom radu fokus je na percepciji potencijalnih partnera prije same interakcije, odnosno kada nam o osobi o kojoj donosimo određenu perceptivnu odluku nedostaju ključne informacije. Testirali smo i eventualne promjene u percepciji s obzirom na fazu menstrualnog ciklusa. Očekivali smo opću tendenciju strožoj procjeni partnera u neizvjesnim uvjetima, no zbog eksplorativne prirode istraživanja postavljena je nul hipoteza za potencijalne razlike u učinku s obzirom na fazu menstrualnog ciklusa. Od mjernih instrumenata korišteni su Revidirani inventar socioseksualne orijentacije (SOI-R) i Inventar vrijednosti kao partnera (MVI-7) te 28 parova fotografija lica muškaraca, pri čemu je jedna fotografija u paru bila zamućena i predstavljala uvjet neizvjesnosti. Rezultati pokazuju da su žene općenito strože prilikom procjene lica na fotografijama u uvjetu neizvjesnosti. Nadalje, ovaj je učinak jednak u obje faze menstrualnog ciklusa, a nisu utvrđeni ni moderacijski učinci SOI-R i MVI-7 na odnos između faze menstrualnog ciklusa i procjene lica. Ovime su potvrđene osnovne postavke EMT hipoteze, ali nismo došli do novih spoznaja o eventualnim kontekstualnim čimbenicima koji bi mogli utjecati na efekt.

Abstract (english)

The theoretical framework of this thesis is based on the Ovulatory Shift Hypothesis, the Parental Investment Theory, and the Error Management Theory (EMT). EMT suggests that human perception, decision-making, and various cognitive biases have evolved to minimize errors that could have serious consequences on survival and reproduction. We focused on mating cognition pre-interaction with potential mates when key information about the person is missing. The study tested potential changes in such cognitions depending on the menstrual cycle phase. We predicted that women will be stricter when evaluating the blurred photograph of a potential partner as opposed to a regular photograph. However, due to the exploratory nature of the study, a null hypothesis was set for potential differences in the menstrual-cycle-phase effect. The instruments used were the Revised Sociosexual Orientation Inventory (SOI-R) and Mate Value Inventory (MVI-7), as well as 28 pairs of photographs of men, with one photo in each pair being blurred to represent the uncertainty condition. Our results show that, when uncertain, women tend to rate faces more strictly. This effect was observed to be consistent across the cycle. Additionally, no moderating effects of SOI-R and MVI-7 were found on the relationship between the menstrual cycle phase and face evaluation. To conclude, we confirmed the basic assumptions of the EMT hypothesis, but without gaining additional information about possible contextual factors that could influence the effect.
