Experimental sessions were video-recorded using an 8 mm camcorder.
The roles of video, both as a mass medium and as personal camcorder, are discussed and analysed in communicative terms.
The camcorder was mounted on a tripod unobtrusively in the corner of the room and had an unobstructed view of the experimental situation.
A camcorder with a time-stamped video image was used for recording infants' behaviour during the experimental session.
The order of conditions was randomized within and between each visit and all segments were videotaped with a portable camcorder.
Speaker and camcorder were concealed from children's view by two overlapping black fabric curtains.
One camcorder was located towards the front of the horse, one towards the back of the horse and two towards the lateral aspect of the right side of the horse.
With the camcorders having the frequency of 30 frames per second, the time was noted when the foot was leaving the ramp surface at the first steady step.
