„Vzpomeňme, kolik telefonních čísel jsme si byli schopni zapamatovat v dobách, kdy jsme se ještě nespoléhali na adresáře v našich mobilních telefonech,“ uzavírá profesor Horáček.Tak ano. V mym okoli vidim, ze kdo si koupil auto a prestal chodit pesky, tak za rok dva pribral na vaze... Tohle je asi podobny. Asi si kazdej clovek musi sam rozhodnout na ktery cinnosti se chce v zivote specializovat. Pokud chce bejt nekdo prebornik v pamatovani telefonnich cisel, tak klidne

[...] the participants in the experimental group did not use the GPS navigation implemented in AR glasses as intensively as it was desired by the protocol. They reported as a reason almost exclusively the technical problems with the AR glasses. Due to technical issues with operating system the Vuzix M100 glasses have been replaced in five subjects during the intervention. Some other issues have been reported using user experience questionnaires (six subjects reported also inaccuracy of GPS signal or sudden crash of the GPS guide—Osmand application—during active outdoor navigation, two sub- jects complained about an unpleasant noise generated by the device, and seven subjects reported uncomfortable or insufficient placement of the device on the head during movement) [...]
Third, the intervention effects on hippocampal FC were not strong enough to survive conservative correction for multiple comparisons. (Note: concerning the statistical testing of the intervention effect, we have some albeit not fully conclusive evidence that it is not likely attributable solely to false positives. Overall, we have observed 15 significant results out of 122 hypotheses tested (total numbers decreased by one because one of the connections is between the right and left hippocampi). The probability of observing 15 or more false positives instead of the expected 6 (=∼122∗0.05) under independence of the tests is p=∼0.0012 (derived from binomial distribution). This strongly suggests that these do not all constitute false positives. However, the tests are not necessary fully independent, and thus such comparison to binomial distribution is not an exact statistical test.Zdá se mi to, nebo tady obhajují p-hacking? Každopádně, závěr studie je, že se nepodařilo prokázat změny ve funkcionálním propojení.
Despite the above-mentioned limitations, the observed results are in line with the original hypothesis of decrease of functional connectivity of the hippocampal region and provide more specific conjecture about which connections are particularly weakened by this augmented reality (GPS) intervention. Thus, the follow-up studies can narrow down the scope to those detected areas."To co jsem naměřil odpovídá mým předsudkům."
The observed alterations in hippocampal FC were not connected with substantial behavioral effect as the partici- pants from the experimental group did not show any decline in ability to effectively navigate after the intervention with AR glasses when tested in virtual city environment. Congruently, it was documented previously that physiological changes in functional connectivity may precede cognitive and long-term structural changes due to present compensatory mechanisms [47]. Nevertheless, the lack of direct (negative) impact of decreased right HPC FC on navigation abilities might be due to short duration of the applied intervention and/or limited usage of AR glasses by the participants."Znamenají naše výsledky něco v praxi? Těžko říct, možná. Lidi se po třech měsících orientovali pořád stejně dobře."
