Possible consequences of non-pharmacological interventions for COVID-19 on human behavior research.

	Facemasks/shields	Gloves and disinfection practices	Safety distance (e.g., 1 m, 2 m)
Changes	Facial features	Haptic perception	Social interaction
	Breathing patterns	Pain processing	Subjective experience of the experiment
	Olfaction
Examples of research topics affected	Autistic spectrum	Proprioception	Emotion processing
	Imitation	Placebo analgesia	Dyadic interaction
	Attachment	Interpersonal relation	Social stress
	Emotion processing	Social touch
	Face mimicry	Pain
	Dyadic interaction	Tactile discrimination
	Social stress
	Meditation
	Relaxation
	Interoceptive exposure
	Olfactory discrimination
	Partner selection
	Olfactive chemo signaling
	Disgust processing
Unintended consequences		Fear of contamination and increased anxiety that disinfection was insufficiently performed, particularly with re-usable equipment (e.g., EEG electrodes, earphones, keyboards)	Reluctance and increased anxiety about being in an indoor, confined space (e.g., magnetic resonance imaging scanner)
		Increased anxiety or reluctance to touch items in the experimental setting, particularly food, or drinks (e.g., outcomes like the Taste test)	Increased preparation time, risk of errors due to omissions, or in complex procedures due to reducing presence in the laboratory (e.g., only one experimenter)
