►Visual Imagery: Create a mental Visual Imagery: Create a mental picture to represent the wordspicture to represent the words ““One Sun” peg and link systemOne Sun” peg and link system

►First, you memorize the rhyming “Peg” First, you memorize the rhyming “Peg” words:words:

►Then, you “link” each word you want Then, you “link” each word you want to remember to the appropriate peg to remember to the appropriate peg by creating a vivid mental imageby creating a vivid mental image Example: if your first word is “bread”, you Example: if your first word is “bread”, you

can imagine bread being burnt to a crisp can imagine bread being burnt to a crisp by a giant, hot, yellow sunby a giant, hot, yellow sun

Weird, exaggerated images are more Weird, exaggerated images are more memorablememorable

►How many of the 10 words can you How many of the 10 words can you remember?remember?

►According to Paivio (1986), this works According to Paivio (1986), this works because imagery provides a second because imagery provides a second kind of memory code, and 2 codes are kind of memory code, and 2 codes are better than onebetter than one

►We can encode information visually We can encode information visually (by images), acoustically (by sounds), (by images), acoustically (by sounds), and semantically (by meaning)and semantically (by meaning)
