| Abstract: | 9 experiments designed to investigate the effect of food deprivation on perceptual-cognitive processes are examined in detail. An effect is revealed in only some of these experiments. The deviating results are explained by assuming that motivational state will not affect perceptual-cognitive processes unless the material presented is meaningful in relation to the motivational state. Examination of operational definitions indicate that: (1) the processes studied may be more meaningfully termed imaginary than perceptual, and (2) the motivational state of hunger may rest on the expectancy of the Ss as to when they may next receive food, rather than hr. of food deprivation.
