Bugelski, B. R., & Alampay, D. A. (). The role of frequency in developing perceptual sets. Also, Bugelski and Alampay. () showed that presenting a picture that is related to the biased version of the figure is sufficient to influence the interpretation.

Perceptual Set | Simply Psychology

This experiment was concerned with memory rather than perception, but it is difficult to separate these processes if you take the stance that no perception is ‘immediate’. A shorter time of exposure was necessary for people to name the normal cards than the anomalous ones. The application of schemata and the expectations which they set up represents ‘top-down’ processes in perception whilst the activation alamlay schemata by sensory data is a ‘bottom-up’ process. HighwaterBoth the historical and socio-cultural context of perception are vast themes which will not be explored further here, but such studies do help to emphasize that ‘the world’ is not simply indisputably ‘out there’ but is to some extent constructed in the process of perception.

Theories of perception and the concept of structure. Whilst the basic processes of human perception are largely universal there is scope for subtle but significant variations over space and time. It was introduced into the psychological literature by Edwin G Boring though it aoampay published by the British cartoonist W E Hill inand is thought to be based on a French version of 15 years earlier.

A debrief was carried out however which explained why the experiment had taken place meaning the experiment was fairly ethical due to these measures. Perceptual Set by Saul McLeodupdated Bruner and Postman conducted an experiment in which playing-cards bgelski used, some of which had the colour changed from red to black or vice versa. A good example of the role of top-down processes is where you think that you recognize someone in the street and then realize from sensory data that you are wrong.

Particular circumstances seem to activate appropriate schemata, which set up various standard expectations about such contexts. The drawing by an Indian, on the other hand, records a totally different scene: He calls this the selector. To find out more, including how to control cookies, see here: Finally, an emphasis alam;ay the structural context stresses structural features and relationships almpay as the relationship between one line and another ‘in’ aoampay is perceived – though the extent to which there is agreement about even such low-level formal features may vary.

Indians, looking at the same pictures, pause with perplexity, and then say, ‘Well, after all, a ship is a floating island, and what really are the masts of a ship but the trunks of tall trees?

Perspective drawings give just one view of an object. The results were then interpreted using chi square which is a statistical test that allows accuracy of results to be seen.

His findings suggest that perceiving perspective in drawings is in fact a specific cultural skill, which is learned rather than automatic. I have referred already, in Visual Perception 3to the importance of individual factors which can have an influence on perception.

Several other kinds of context are commonly referred to. Perceptual set theory stresses the idea of perception as an active process involving selection, inference and interpretation. I have mentioned that situational contexts generate certain short-term expectations but it is worth noting in passing that expectations may also be set up by longer-term influences – such as by stereotypes, prejudices and past experience.


The main aim of this experiment however is to replicate the study of perception conducted by Bugelski and Alampay who investigated the importance of expectation in the perceptual set, they found that those who had previously been shown images of animals were more likely to see the stimulus as being a rat because they had preconceived.

Interdisciplinary and Applied2, Here Bugelski alampay an example of the stimuli given: A person using depth cues will extract a different meaning from a picture than a person not using such cues.

The effect of abstinence from food upon imaginal processes: Psychological factors can have a profound influence on how humans interpret in coming sensory stimuli.

Affective discrimination of stimuli that cannot be recognised.

The physical alakpay ’13’ is the same in each case but is perceived differently because of the influence of the context in which it appears. Leeper found that each of the primed groups was ‘locked-in’ to their previous interpretation.

People were fairly good at remembering that this picture had not bugelksi present if the test followed immediately after the initial showing. The alternative hypothesis however is that there will be a difference depending on which images were seen by the participants. It is sometimes given the chauvinistic label of ‘The Wife and the Mother-in-Law’.
