1/0:+ =  following gaze in test but not control trial.

- =  following the gaze in both trials or in none ( = tie).

Lat:+ =  shorter latency in test than control.

- =  longer latency in test than control or no reaction in either trial (tie).

1/0 refers to whether or not the first detectable head turn of the subject followed the direction of the demonstrated head movement within the first two seconds of the cue presentation. Latency (Lat) refers to if the subject followed the gaze cue earlier in the test than the control trial.
