| Apr 21, 2022 at 15:32 | comment | added | EdM | Please edit the question to say more about what you mean by "negatively rated button press." Is the "negative rating" something that's known at the time of the button press, or is that "negative rating" of the button press determined by the participant at some time during or after the measurement of facial muscle activity? Please do that by editing the question, as comments are easy to overlook and can be deleted. | |

| Apr 20, 2022 at 10:01 | comment | added | Leon | Ah okay. I took that information from websites that say that in regression we test how x influences y and that changing the order of the variables leads to different results. I think that the order is not clear in my case. Does the subjective judgment of valence come first or does the physiological reaction of valence come first (James-Lange theory). I feel like I would need to make a decision (assume one theory but not the other) when using regression, whereas a t-test would just test if there is a significant difference. | |

In fact, your t-test can be thought of as a very simple form of regression, with a single binary "predictor" (positive vs negative button press) and a continuous outcome (muscle activity). Correcting for within-participant correlations is critical, as you otherwise overweight those with more observations. | |
