| Unit Three- Module 21 Perception: Influences on Perception | Perception: Influences on Perception |
| Selective attention | The focussing of our conscious awareness on a particular stimulus. Through selective attention, our awareness focusses on a minute aspect of all that we experience. |
| Cocktail Party Effect | The ability to attend to one of several speech streams while ignoring others, as when one is at a cocktail party. |
| The Stroop Effect | The delay in reaction time between congruent and incongruent stimuli. For example, the time it takes a participant to name the colour of ink in which a word is printed is longer for words that denote incongruent colour names than for neutral words or for words that denote a congruent colour. |
| inattentional blindness | Failing to see visible objects when our attention is directed elsewhere. |
| inattentional deafness | The failure of unattended auditory stimuli to register in the consciousness. |
| change blindness | A phenomenon of visual perception that occurs when a stimulus undergoes a change without this being noticed by its observer. |
| change deafness | A phenomenon of auditory perception that occurs when a stimulus undergoes a change without this being noticed by its observer. |
| pop-out effect | One or more basic features will mark a stimulus as distinct from the other stimuli, hence allowing the target to be easily detected and identified regardless of the number of distractors. |
| choice blindness | The inability to detect a change between an object/image we have chosen and a similar object/image. |
| perceptual set | A mental predisposition to perceive one thing over another. In other words, it is a set of mental tendencies or assumptions that affects, top-down, what we hear, taste, feel, and see. |
| perceptual schema | A schema is a mental model that provides a frame for interpreting information entering the mind through the senses or for activating an expectation of how a particular perceptual scene may look. They allow us to organize and allow us to interpret unfamiliar information. |
| context | Context refers to the situation or circumstances in which an event occurs. |
| context effect | Context effect is an aspect of psychology that describes the influence of environmental factors on one's perception of a stimulus. The impact of context effects is considered to be part of top-down processing. |
| motivation | Motivation is the process that initiates, guides, and maintains goal-oriented behaviours. Motivation involves the biological, emotional, social, and cognitive forces that activate behaviour. |
| emotion | Emotions are psychological states brought on by neurophysiological changes, variously associated with thoughts, feelings, behavioural responses, and a degree of pleasure or displeasure. |
