After you have mastered the material in this chapter, you will be able to: The memory; information stored in memory sensory, short-term, long-term; information processed and applied reasoning, problem solving, skill, error; emotion influences human capabilities; each person is different. | Lecture 2 HUMAN COMPUTER INTERACTION 1 Summary In previous lecture we learnt about, Basics of Human Computer Interaction Alarm Clock Example Dos time versus software application Don Norman’s Door Example The human Information i/o visual, auditory, haptic, movement 2 TODAY’S OUTLINE The MEMORY Information stored in memory sensory, short-term, long-term Information processed and applied reasoning, problem solving, skill, error Emotion influences human capabilities Each person is different 3 Memory Memory Without the capacity to remember and to learn, it is difficult to imagine what life would be like, whether it could be called living at all. Without memory, we would be servants of the moment, with nothing but our innate reflexes to help us deal with the world. There could be no language, no art, no science, no culture.’ (Blakemore, 1988) Memory There are three types of memory function: Sensory memories Short-term memory or working memory Long-term memory Selection of stimuli governed by level of arousal. Attention Rehearsal sensory memory Buffers for stimuli received through senses iconic memory: visual stimuli echoic memory: aural stimuli haptic memory: tactile stimuli Examples “sparkler” trail stereo sound Continuously overwritten Short-term memory (STM) Scratch-pad for temporary recall rapid access ~ 70ms rapid decay ~ 200ms limited capacity - 7± 2 chunks Examples 212348278493202 0121 414 2626 HEC ATR ANU PTH ETR EET (The Cat Ran Up The Tree) Long-term memory (LTM) Repository for all our knowledge slow access ~ 1/10 second slow decay, if any huge or unlimited capacity Two types episodic – serial memory of events semantic – structured memory of facts,concepts, skills semantic LTM derived from episodic LTM Long-term memory (cont.)
