Correlations between gaze duration spider–bird/snake-bird and autonomic responses spider–bird/snake-bird.

Spider–Bird Snake–Bird
rPhobic rControl Z rPhobic rControl Z
Heart rate −0.44 0.48 −2.21 0.18 0.35 −0.41
Skin conductance −0.25 0.78 −3.04 0.49 0.43 0.18

Heart rate: NPhobic = 12, NControl = 14; Skin conductance: NPhobic = 13, NControl = 15. Bold: p < 0.05 (two-tailed). Z, Fisher's Z transformation, testing the difference between the two group correlations.
