![]() There should be a change in an action potential in order to evoke a response. The stimulus below threshold is referred to as subliminal. ![]() But stimulus having intensity below the threshold will not be able to. ( Physiology) A stimulus with an adequate intensity can generate an action potential. ( psychology) A stimulus below the threshold-line for conscious perception but can evoke affective reactions without awareness ![]() AAI9109237.( physiology) A stimulus inadequate to generate an action potential and thereby does not evoke a response Messina, James, "The effects of subliminal stimuli in naturally occurring mood states on the performance of a perceptual task" (1990). Psychology|Experiments|Behaviorial sciences Recommended Citation Additional research studies were suggested for the investigation of affect-cognitive interactions. Recommendations were offered for future research examining the influence of subliminally presented task information on performance. Subjects in elated mood states located significantly greater number of the hidden names than subjects experiencing depressed mood states. However, the effects of mood state did significantly influence the number of embedded names found in the puzzle task. Mood state did not produce significant differences on the time taken to locate the embedded names. Results indicated that the subliminally supplied information produced no significant performance difference in either the amount of time taken to locate the embedded names or the number of names found in the puzzle. The dependent measures for these analyses were the time taken to locate the embedded names in the puzzle tasks and the number of embedded names found. Analyses of variance were performed to examine the differential effects of the subliminal information and mood state. Through the use of a tachistoscope, subjects were subliminally exposed to either the correct locations of the embedded names, incorrect locations, or a control stimulus supplying no information to the task. The perceptual task of this study was to find embedded names that were hidden in picture puzzles composed of people and objects. Fifty-one subjects ranging in educational experience from high school through graduate school were initially asked to rate their present mood on a modification of Wessman and Ricks' Elation vs. It was further reasoned that the individual's naturally occurring mood state might produce differential performance on the perceptual task. It was expected that subjects subliminally supplied with correct, incorrect, and no information regarding the location positions of answers to a perceptual task would show performance differences on that task. ![]() Additional research evidence has suggested that subjects experiencing relatively elated moods may learn and perform more efficiently in certain tasks than subjects experiencing depressed moods (Bower, 1981 Izard et al., 1965 Messick, 1965). Previous research had indicated that a stimulus presented below the level of awareness and not consciously perceived may undergo processing and analysis with demonstrated influences across a range of behavior (Dixon, 1981). The effects of subliminal stimuli in naturally occurring mood states on the performance of a perceptual taskīased upon evidence drawn from previous studies of the processing of information below awareness and the effects of mood state on performance, this study attempted to investigate the effects of subliminally presented location cue information and the individual's naturally occurring mood state on the performance of a perceptual task. ![]()
