Comparative Effectiveness of Tv Production Variables

A Signal Detection Approach to the Study of Television Production Effects

“…It may also be the case that conventional criteria for significance will not always be relevant in applied situations; if it turned out that 20% was the maximum 'increase' obtainable by manipulation of production techniques, then that, for example, would relate to the extent that the television producer could wield his 'invisible hand'. Coldevin (1976) has proposed twelve variable presentational factors, not only technical, but including 'subject matter' and 'performer characteristics' as well; and Baggaley et al, (1979) discuss the possibility that such cues 'summate' or reinforce one another for a combined effect.…”

“…The most substantial body of research regarding TV production effects is found in the literature of educational technology (Baggaley & Duck, 1976;Coldevin, 1976). Coldevin reviews over 40 empirical studies dating since the early 1960's, concerning:…”

“…In previous literature, the terms 'formative evaluation and research' have been used somewhat interchangeably. Even conventional uses of the term 'formative' give rise to confusion, being used to describe the often quite distinctive types of work conducted during programme formation and concerning programme format -e.g., presentation/ technical variables; content/subject matter organization; and performer characteristics (Coldevin, 1976;BaggaIey, 1986a). The label 'formative research' should perhaps be reserved for those formative and quasi-formative studies which, whether by accident or design, shed generalized light on effective programme design.…”
