What does subliminal perception mean

Begin by reviewing the work in the previous class — emphasizing that subliminal perception is possible but that the possibility of subliminal persuasion being at question. Review the examples of attempts at subliminal persuasion that students brought in last time, as well as any new evidence they have found, to identify the specific claims made e. Highlight for students the ways in which these purported and feared outcomes of subliminal messaging compare to the kinds of dependent variables used in the research discussed in the last class.

For example, how comparable is interpreting ambiguous stimuli in schematic-consistent ways after exposure to a prime to getting up out of your movie seat to go and buy popcorn? Briefly walk students through how researchers might test the claims being made about the effects of subliminal messaging. For example, using the classic subliminal messages in movie theater ads story, guide students to generate a study such as this:.

Use this as an opportunity to review research design random assignment, IV, DV, operationalization of variables, ethical issues, etc.

Engage students in a discussion of the research evidence for subliminal persuasion of attitudes. Two good studies to cover are:. The authors did not measure actual behavior. Only thirsty people said they were more likely to buy a specific beverage; people who were not already thirsty showed no response to the subliminal message. If given the opportunity, would the participants in the Karremans et al. If you have time, have students design a research study that would test some of the hypotheses raised in this discussion in order to help them apply their understanding of research methods and see how scientific research could help us answer these questions.

If you have a third day to spend on this unit, assign students to find additional research that has investigated these questions about subliminal persuasion, asking them to come to class next time prepared to share and discuss their findings. A list of possible sources is included below. You could also assign each student one article from this list rather than having students search for their own articles. Regardless of whether you take 2 or 3 days on this unit, be sure to leave students with these take-home messages:.

We do not have to be consciously aware of or intentionally pay attention to stimuli in our environment for them to be perceived. We can observe evidence of this subliminal perception in basic priming effects, top-down processing, schematic processing, and so on. For example:. However, the kinds of subliminal influence that happens e. Andersson, O. Subliminal influence on generosity.

Effects of mere exposure have even been obtained for stimuli that were perceived for only one millisecond. Perceivers can to some extent infer the valence is something good or bad? This is shown in research on the subliminal perception of short positive e. Subliminal perception is controversial mainly because of the notion of subliminal persuasion: The strategy that may be used by marketers or politicians to deliberately influence customers or voters subliminally.

This however, turned out to be a myth. Perhaps because of the media attention subliminal perception and persuasion sometimes receives, most of the American population does believe subliminal persuasion to have far reaching consequences. Importantly, research on action priming has shown that subliminal stimuli can trigger only actions a receiver of the message plans to perform anyway.

However, consensus of this finding remains unsubstantiated by other research. Most actions can be triggered subliminally only if the person already has the potential to perform a specific action.

The following sections have more information on specific studies which investigate the effectiveness of subliminal stimuli. Some studies have looked at the efficacy of subliminal messaging in television. Subliminal messages produce only one-tenth of the effects of detected messages and the findings related the effects of subliminal messaging were relatively ambiguous. Karremans suggests that subliminal messages have an effect when the messages are goal-relevant.

However, those who were not thirsty were not influenced by the subliminal messages. Karremans did a study assessing whether subliminal priming of a brand name of a drink would affect a person's choice of drink, and whether this effect is caused by the individual's feelings of being thirsty. In another study, participant's ratings of thirst were higher after viewing an episode of The Simpsons that contained single frames of the word "thirsty" or of a picture of a Coca-Cola can.

Many authors have continued to argue for the effectiveness of subliminal cues in changing consumption behavior, citing environmental cues as a main culprit of behavior change. Authors who support this line of reasoning cite findings such as the research that showed slow-paced music in a supermarket was associated with more sales and customers moving at a slower pace.

Findings such as these support the notion that external cues can affect behavior, although the stimulus may not fit into a strict definition of subliminal stimuli because although the music may not be attended to or consciously affecting the customers, they are certainly able to perceive it.
