Page 10 Information-processing theories Information-processing theories –Subdivide memory into 3 different stores Sensory, Short-term, Long-term Sensory, Short-term, Long-term – Atkinson & Shiffrin Model of Memory Storage = incoming info passes through 2 temporary storage buffers 1) Sensory 2) Short Term then 3) Long Term

Working Memory – (Baddeley) allows temporary storage & manipulation of the info necessary for complex cognitive tasks ( language comprehension, learning, reasoning ) It require the simultaneous storage& processing of info. – Executive control system: attentional-controlling system – Phonological rehearsal loop: stores & rehearses speech-based info & is necessary for the acquisition of both native & second-language vocabulary. – Visuospatial sketchpad: manipulates visual images – Episodic Buffer: integrates info before LTM

Page 24 Reconstructing memoriesReconstructing memories – Source monitoring: make attributions about where memories come from (Marcia Johnson) – Source monitoring error: mistake in the source – Reality Monitoring: deciding whether memories are based on external (actual events) or internal (thoughts or imagination)

Page 25 Retention – the proportion of material retainedRetention – the proportion of material retained – Recall: remember without cues – Recognition: remember with cues – Relearning: memorize again to measure how much time/practice before learning occurs Ebbinghaus’s Forgetting Curve: retention reduces after learning something compared to retention after learning something meaningful Ebbinghaus’s Forgetting Curve: retention reduces after learning something compared to retention after learning something meaningful
