Sensory Organs

(Eye, ear, etc.)

Stimuli Sensory Registers

(visual, auditive, haptic, etc.)

Pattern Recognition Long Term Memory (LTM)

declarative knowledge, procedural knowledge

Short Term Memory (STM) = Working Memory

controlled cognitive processes (e.g. decisions, memory search)

Motor Systems

(e.g. coordination of arm-hand-finger systems, eye movements, etc.)

Attention

Chunks in Short Term Memory

  • Capacity (in general): approx. 3 (2 to 4) chunks

–for very short durations (2s) up to 7 (5 to 9) chunks

Long Term Memory

  • Declarative knowledge
  • Procedural knowledge

–motor knowledge vs. cognitive knowledge

Recognition vs. Recall

  • Of what brand is your bike?

–Answer has to be produced –Example: grep “recall“ chapter??.tex

  • Is your bike of brand XYZ?

–Yes/no decision only

Evaluation of Learning Methods

  • Control group: learns without method (trial & error)
  • Transfer group: learns with new method (e.g. course)
  • Measuring the time until a certain achievement is reached

9 Slide Based on Material by A. Butz & A. Krüger

Transfer group is learning Transfer group is applying (doing) Control group learns by doing

Trace Decay Theory

  • Based on work by psychologist Hermann Ebbinghaus
  • Experiment: Rehearsing non-sense syllables

–Memory fades just by passage of time –Theory (Thorndike 1914): Memory trace (access path) decays

  • More recent insights:

–Not only time is relevant but also knowledge activation –When and how often the knowledge was accessed?

  • Rarely used knowledge fades over time

Interference Theory

  • New knowledge replaces old knowledge
  • Example: Moving house, street names
  • Example: Changing school, names of other pupils
  • Example: Unused foreign language
  • other examples??

Factors Slowing Down the Forgetting Process

  • Strong emotions:

–Associated knowledge is kept longer
 in memory

  • Context:

–Learning and recall within the
 same context (e.g. room)

Cocktail Party Effect

  • Selective hearing
  • Organized conversation in

presence of many different voices

  • Irrelevant voices attenuated

by up to 15dB

–only perceived volume –not physically!

  • Function of the human brain,

currently not realizable by technology
