1. Memory

2. Chapter 7:
Scientists found that a fetus will remember
and respond to acoustic signals delivered
up to 24 hours apart at about 30 weeks
after conception. Theoretically, it's even
possible for humans to form memories
from inside the womb.

3. Your long term memory can
store up to one quadrillion
bits of information over the
course of your life, more
than all the printed material
in the library of Congress!

4. Stages of Memory
• Memory systems act
like a computer with:
– Encoding
• Converting information
into a useable form
• Typing data into a
On average, a man’s brain is 8-10% larger than a woman’s. However, female
computer
brains tend to have more nerve cells and cellular connections, allowing
– Storage
for more efficient and effective brain functionality.
• Holding this information
in memory for later use
– Retrieval: Taking
memories out of
storage

5. Studies show an improved ability to
recognize visual patterns and even
some math problems after one good
night sleep. Many believe our brains
"consolidate" or solidify recent
memories while we're asleep.

6. Neuron loss starts to ramp up after 30.
Between the ages of 25 and 75, it's
believed that our ability to learn and
remember new things decreases by 50%.

7. Blueberries contain a known memoryboosting phytochemical called
anthocyanin and other nutrients that may
help support memory.

8. St ages of Memor y
• Short-Term
Memory (STM)
– Working Memory
• Another name for
STM

• especially used for

memories brought on by other senses.

The conscious brain is capable of

– String of numbers is

– Typically part of
intelligence tests
• Magic Number 7+/-2:
– STM is limited to
holding seven (plus or
minus two)
information bits at
once

10. • Believe it or not, this is
true! Sitting up straight
allows more oxygen to
reach your brain and
looking upward helps to
access the "thinking"
part of your brain.
