MEMORI • Atkinson-Shiffrin Model • Level of processing approach • Tulving’s model • Parallel Distributed Processing approach

MODEL MEMORI Atkinson-Shiffrin Model (1968) External Input Sensory register (sensory memory) Lost from SR Short-term store (Short-term memory) Lost from STM Long-term store (Long-term memory) Decay, interference, And loss of strength In LTM

MODEL MEMORI Control processess • = strategi yang digunakan individu secara fleksibel & spontan • Terdiri dari rehearsal, the silent repetition of information that encourages it to recycle through STM • Strategi apa yang akan digunakan untuk menyimpan informasi? Mental picture / sound?

MODEL MEMORI Pendekatan Level-processing Craik & Lockhard (1972) • • • informasi yang bermakna dan diolah semakin dalam, akan lebih lama bertahan efektif salah satu pengolahan adalah rehearsal. Ada dua macam rehearsal: – Maintenance rehearsal – Elaborative rehearsal efektif

MODEL MEMORI Tulving’s model (1972) • Tiga kategori utama: – Episodic memory – Semantic memory – Procedural memory first system developing during infancy, 2 nd is semantic, 3 rd is episodic • Fokus pada short-term memory

MODEL MEMORI Characteristic 1. Source of info 2. Units of info. Episodic M. Sensory exp. Episodes & event 3. Organization Time-related Concepts, ideas, & facts Conceptual 4. Emotional content 5. Forgetting 6. Time to remember 7. How tested in laboratory More important Less important Great Relatively long time Recal of particular episodes Less useful Small Relatively short time General knowledge 8. Usefulness Semantic M. Comprehension More useful

MODEL MEMORI Proses distribusi paralel James Mc. Clelland (1981) • Neural networks= proses kognitif akan berjalan seperti network, dimana aktivasi satu memori tertentu akan menyebabkan aktivasi memori lain.

MODEL MEMORI Karakteristik PDP • • Memory tetap dapat bekerja, meskipun input tidak lengkap Beberapa petunjuk lebih efektif dibanding yang lain

Short- Term Working Memory • • Working memory Forgetting Decay and interferences Capacity Memory Codes

STM Environmental input Sensory Register -Visual -Auditory STM Temporary Working Memory Control processes: Rehearsal Coding Decisions Retrieval strategies LTM Permanent memory store

• STM memilik keterbatasan baik dalam kapasitas maupun jangka penyimpanan. • Informasi akan hilang dalam 20 -30 detik jika tidak diulang/ rehearsed • STM diperlukan ketika melakukan sebagian besar tugas kognitif. Hal ini menjadi petunjuk bahwa STM memiliki peran penting sebagai memori kerja yang memelihara dan memanipulasi informasi. • Working memory: Penggunaan STM sebagai penyimpanan informasi sementara yang diperlukan untuk menyelesaikan tugas

Forgetting • The label STM indicates that information in STM is lost rapidly unless it is preserved through rehearsal. • Probability of a recall decline rapidly after 18 seconds verbal inform. Must be rehearsed to keep it active in LTM (Peterson & Peterson)-

Decay and Interference • How did the information loss take place? decay or interference? • Interference: forgetting occurs because other material interferes with the information in memory • Decay: information is spontaneously lost over time, even when there is no interference from other material. • Waugh and Noeman found that information loss is due more to interference more than by decay.

Forgetting from STM: Exp. • DO: Look at these letters: BXKVP Chek with memory simulation in Encarta

EXP • Do: Look at these numbers: 369 • DO: Read the number backward

Forgetting from STM: EXP • DO: Tell us, what were the letters you saw before the numbers? • Can You memorize them?

• Interference: Retroactive Vs Proactive • Retroactive interference: Kelupaan muncul karena interferensi dari material yang diterima setelah belajar/ mengingat • Proactive: Kelupaan terjadi karena material yang diterima sebelum belajar/ mengingat Diatasi dengan membuat informasi berbeda dari material sebelumnya.

CAPACITY of STM • It can hold only about 7 items/ Magical number 7 • Checked through memory span. Memory span: The number of correct items that people can immediately recall from a sequence of items TRY : TMFJRLB ASDRTYUGP THJKYPLKJ LKJHGFM

Helping the STM • Chunking: mengelompokkan item ke dalam potongan-potongan/ unit yang didimpan dalam STM EXP: Read FGHJKLMBOP then Read: FGHJK- LMBOP Which one will be easier to remember? • Miller: Capacity of STM should be measured in terms of chunk, not items.

Control Processes • Control Process 1: • Acoustic codes/ kode akustik: speech based • Semantic code/ kode semantik: meaning based Control Process 2: • Rehearsal • Subvocalizing: Silently speaking to oneself help us remember esp complex and detailed inform) but hinder reading speed. • Visual codes: more memorable when name is given.

Working Memory Badeley’s model, const of: 1. Phonological loop: memelihara dan memanipulasi informasi verbal/ wicara 2. Visuospatial sketchpad: memelihara dan memanipulasi informasi visual 3. A central executive: Memilih strategi dan mengintegrasikan informasi Current view: STM is a component of working memory

Group Assignment: • Cari ayat Al Quran berkaitan dengan pengingatan • Buat Summary dari materi Memori pada bacaan yang dibagikan • Buat pertanyaan kelompok berdasar bacaan tersebut? Apa yang ingin kelompok anda ketahui lebih lanjut? Minimal satu orang 1 pertanyaan • Kumpulkan pada minggu depan
