Samenvatting	Psychophysiological measurement records the body's continuous responses — heart rate, skin conductance, facial muscle activity, and more — while people are exposed to media, providing real-time, covert indicators of attention and emotion. Reviewed for communication by Ravaja, these measures sidestep the biases of self-report and capture moment-to-moment processing as a message unfolds.	Media richness analysis applies Daft and Lengel's media richness theory to evaluate communication channels by their capacity to carry rich information and to assess how well a channel fits the equivocality of the task at hand. Rooted in organizational communication, it provides criteria — feedback immediacy, multiplicity of cues, language variety, and personal focus — for ranking channels from lean (a memo) to rich (face-to-face) and for diagnosing whether managers and teams are matching channel to message appropriately.
