PSYC-223 Chapter Notes - Chapter 7: Frontal Lobe, Eyewitness Testimony, 18 Months
Document Summary
Babies begin to remember at a few months and can store memory for days and weeks. Collier: found that infants will remember that moving their leg will move the mobile attached to it (remembered how to do it weeks later even with only one trial) 1) an event can be remembered. 2)the event will be forgotten with time 3)the event memory can be dredged up with a reminder (ie shaking the mobile) Memory growth occurs constantly over the first 18 months (memory less than a week in young babies, but up to 3 months in 18 month olds) Improvements can be traced to the development of brain structures (hippocampus and amygdala developed by 6 months which initially store information). The structures responsible for retrieving the (cid:373)e(cid:373)ories (cid:894)ie fro(cid:374)tal (cid:272)orte(cid:454), hippo(cid:272)a(cid:373)pus(cid:895) do(cid:374)"t de(cid:448)elop u(cid:374)til later, 2 (cid:455)ears. As the hippocampus and frontal cortex develop over the first 2 years so does memory.
