Q. What can be inferred about the human perceptual system from the facts that it often takes  incomplete & distorted  figures as complete & meaningful  whereas sometimes complete and meaningful   figures as incomplete & distorted? Answer with suitable examples. 10

  1. Human perceptual system is a non static, dynamic system which regularly keeps constructing and reconstructing itself.
    At the same time this system is not a full proof system. There are instances of its failure. Sometimes the failure is due to distorted signals but it also happens due to organismic fators, including motivating, emotion, values, preconceived SETs, etc.
    There can be two aspects to it, firstly, when the signal is distorted but perceived complete. Like in the case of Closure principle of perceptual organisation where we compete the figure with uncompleted information.

    Secondly, there are cases where the stimulus is so clear and still we can’t perceive correctly.
    Like in the case of perceptual defense or delayed response where a clearly identifiable stimulus is misperceived.
    Example- words like ‘sex’ which seems incongruent to subjects may get replaced by a congruent word ‘set’.
    Here a clear stimulus for the word is denied correct perception.
    The experiment of Miller and later by Postman on neutral and taboo words have reflected the same.

    Illusion and other failure of constancy reflects that it’s not a full proof system.
    A good example is Moon Illusion where the same sized and same distant moon appears bigger at horizon.
    Muller Lyer Illusion has a clear stimulus presentation but still the perception fails.
    The osgood’s experiment has shown how people make food related perception on being hungry (Motivation). In his experiment, he showed that people misperceived 400D as FOOD due to hunger motivation.

    We have many more examples to reflect that perception is a dynamic ever changing system with a high degree of stability but can never be considered a full proof system. This nature of perception leads to its disparity with exact physical energy or stimulus.

  2. Substantial answer… Try to be more concise.
    Evidently, human perceptual system is well designed and is naturally equipped with capability for meaningful construction. We can get who is singing even if radio station is not well tuned and is sound is fractured.
    Our perceptual system at the same time is susceptible to illusions. This indicates its limitations. This is, however, species typical limitations and Philo genetic and evolutionary reasons are behind it.

  3. Human perceptual system often takes incomplete and distorted figure and tries to complete it. This is based on the Organisational Perception.

    On the basis of our past experience (learning), we try to complete the figure and also the Hunan system is dynamic, it manipulates with respect to something similar we have already come across, which may sometimes lead to distorted or wrong perception as well. Also what matter here is cognitive (thought process), non cognitive (emotion, motivation), visual cues and many other factors that are responsible for these kind of illusions.

    Below are few of the examples:

    1.) When we see an incomplete triangle/ rectangle, we tend to form a complete image in our mind.

    2.) While writing/ reading even if Experience is written as Experince , we will perceive it correctly.

    3.) Moreover, sometimes it has been seen that because of our cultural impact, we may have a faulty perception & may take the word ‘Sex’ as ‘Set’ bcoz this one is comparatively less threatening.
