Design outcomes

Primary

Measure	Time frame
In experiment 1 main study parameter is the difference in behavioural performance between when an oscillating object is displayed in the background or not. EEG will be used to verify that the frequency tagging techniques has induced the brain synchronization when the oscillating object was displayed. The EEG should not be synchronized when the oscillating object is not displayed. In experiment 2 and 3 main study parameter is the electrophysiological measure of attention allocation. This is quantified computing the power spectrum of an EEG trace. Additionally the study underpins a fundamental psychological mechanism (i.e. attention) which is not known to be influenced from physical characteristic of healthy participants (i.e. sex, body weight, etcetera). It should also be noticed that we are comparing different levels of attention, for instance pay attention or ignore something(s). The effects that will be observed at an electrophysiological level are thus exclusively induced from the experimental setting. For this reason we can exclude that there are other variables than the experimental manipulations which affects the results of our study.	—

Secondary

Measure	Time frame
There are no parameters which might intervene with the main study parameter. The fundamental nature of this study permits to exclude any confounders like body weight, smoking, sex, etcetera.	—
