STIVID: A VBSCRIPT-based program for adding visual and auditory stimuli on videotapes.
Some psychological experiments require placement of visual and auditory stimuli on predefined frames in a videotape. We introduce STIVID (STImuli on VIDeo) as a method of performing this task STIVID can add images, words, simple shapes, and audio tones to specific frames of existing video files created in AVI format. STIVID is written in Visual Basic and uses VBScripts to modify the AVI files. Three applications of this program are discussed: adding stimuli for reaction time experiments with couples watching a relational conflict, use of distractors in ADHD experiments, and placing eye masks on actors in existing videotapes to manipulate perceptibility of the target's facial expression during the mind-reading process.
