| ERP | Amplitude | Contribution of ERP to UI and UX designs |
|
| C1 | (Positivity or negativity) 25–125 ms | C1 reflects the visual activity and attention effects in V1 [74]. |
| P100 | (Positive wave) 50–150 ms | P100 results from early ERP amplitude at the occipital lobe [10]. Some research found it reflected early visuoperceptual processes mediated by attention. P100 is extremely sensitive to high contrast color combination, which is suitable for user experience design research [10]. |
| P200 | (Positive wave) 150–250 ms | It reveals a P200 amplitude increase in response to ugly images, which was probably the result of a negative bias in attentional processes [11, 75]. It is also sensitive to negative emotional pictures. P200 is also the charge of the design affordance [76]. |
| P300 | (Positive wave) 250–350 ms | The P300 peak is shorter for color stimuli [77]. It reflects the distribution of attention and decision-making [25]. It is more positive for consistent and beautiful faces [50]. On the contrary, P300 is also used to explore emotion processing of first impression between emotion and attention [69]. |
| N100 | (Negative wave) 80–120 ms | N100 is associated not only with the physical features in reflection to the attention level but also with the attractiveness of stimuli [78]. It relates to package design. |
| N170 | (Negative wave) 120–200 ms | N170 is the ideal ERP component for facial identification and attractiveness [79, 80]. Happy emotion elicited larger N170 amplitudes [81]. |
| N200 | (Negative wave) 200–350 ms | N200 shows the negative component peaking at 200–350 ms. It reveals the perception of beauty, especially of geometric shapes [69]. |
| N300 | (Negative wave) 270–400 ms | N300 is responsive to picture stimuli and affordance [82, 83]. |
| N400 | (Negative wave) 350–500 ms | N400 activates between poststimulus onset with a frontal-central to central-parietal scalp distribution. N400 is concerned with the measure of semantic processing of words or pictures [83, 84]. |
| N450 | (Negative wave) 380–530 ms | Attractive user interface design evokes more negative amplitudes, which shows a larger N450 [73]. |
| LPP | (Late positive wave) 550–770 ms | Late positive potential mainly oversees delayed aesthetic perception and understanding of the objects [85]. LPP shows a larger response to low aesthetic interfaces than to high aesthetic ones [40]. |
| VPP | (Positive wave) 160–200 ms | Facial stimulus and representing the stage of face structural encoding [80]. It is associated with the visual memory processing because it is closer to the hippocampus. |
