Perception

  1. 1. NATURE OF PERCEPTION FACTORS OF PERCEPTION KINDS OF PERCEPTION PERCEPTION
  2. 2. “ WE DON’T SEE THINGS AS THEY ARE, WE SEE THINGS AS WE ARE.”
  3. 3. NATURE OF PERCEPTION “ The study of perception is concerned with identifying the process through which we interpret and organize sensory information to produce our conscious experience of objects and object relationship.” “ Perception is the process of receiving information about and making sense of the world around us. It involves deciding which information to notice, how to categorize this information and how to interpret it within the framework of existing knowledge. “ A process by which individuals organize and interpret their sensory impressions in order to give meaning to their environment. “Perception is a complex cognitive process this is concerned with selection, organization and interpretation of stimuli”
  4. 4. The Perceptual Process 1.Sensation  An individual’s ability to detect stimuli in the immediate environment. 2.Selection  The process a person uses to eliminate some of the stimuli that have been sensed and to retain others for further processing. 3.Organization  The process of placing selected perceptual stimuli into a framework for “storage.” 4.Translation  The stage of the perceptual process at which stimuli are interpreted and given meaning.
  5. 5. Receiving Stimuli (External & Internal) Selecting Stimuli External factors : Nature, Location,Size,contrast, Movement,repetition,similarity Internal factors : Learning, needs,age,Interest, Organizing Figure Background , Perceptual Grouping ( similarity, proximity, closure, continuity) Response Covert: Attitudes , Motivation, Feeling Overt: Behavior Perceptual Process Interpreting Attribution ,Stereotyping, Halo Effect, Projection
  6. 6. FACTORS INFLUENCING PERCEPTION Subjective Factors/ Factors in the perceiver • Attitudes • Motives • Interests • Experience • Expectations Perception Objective factors/ Factors in the Target • Novelty • Motion • Sounds • Size • Background • Proximity • Similarity Social or cultural factors •Social •Cultural •prejudice
  7. 7. We are required to perceive objects in different manners as compared to their position in the environment. Objects maybe moving or stationary when we have to perceive motion. We may have to locate sounds and voices in the space around us. We are also suppose to perceive form, figure, depth and distance of objects. Types of perception 1) Form perception 2) Size perception/ perception constancy 3) Motion perception 4) Depth perception 5) Time perception TYPES OR KINDS OF PERCEPTION
  8. 8. FORM PERCEPTION We do not perceive the world around us as patches of colour, variation in bight-ness ,or loud sounds and voices. Instead we see trees, tables, buildings and cars; we hear automobile horns, footsteps and words. Perception is a unified experience. If we look at a clock, for example, we don’t see parts, we perceive the whole instrument that we recognize as timepiece
  9. 9. TIME PERCEPTION We often perceive time in our normal daily life. Perception of time is less in children than in elders. Time perception is a field of study within psychology and neuroscience that refers to the subjective experience of time, which is measured by someone's own perception of the duration of the indefinite and continuous unfolding of events. The perceived time interval between two successive events is referred to as perceived duration. Another person's perception of time cannot be directly experienced or understood, but it can be objectively studied and inferred through a number of scientific experiments.
  10. 10. DEPTH PERCEPTION • Depth perception also acts as one of the types of perception psychology. It relates to the way the human eye identifies and contextualizes things in space. • Depth perception is the visual ability to perceive the world in three dimensions (3D) and the distance of an object. • For instance, though the naked eye cannot see the end of a tunnel, it interprets its possible depth through past experiences such as scientific measurements to know how deep the tunnel can be.
