Does immediacy here mean "direct intuitive awareness"?

Milgram's variations[edit]In Obedience to Authority: An Experimental View (1974), Milgram describes 19 variations of his experiment, some of which had not been previously reported.
Several experiments varied the immediacy of the teacher and learner. Generally, when the victim's physical immediacy was increased, the participant's compliance decreased. The participant's compliance also decreased when the authority's physical immediacy decreased (Experiments 1–4). For example, in Experiment 2, where participants received telephonic instructions from the experimenter, compliance decreased to 21 percent. Interestingly, some participants deceived the experimenter by pretending to continue the experiment. In the variation where the "learner's" physical immediacy was closest, where participants had to physically hold the "learner's" arm onto a shock plate, compliance decreased. Under that condition, 30 percent of participants completed the experiment.
