Dose gender affect memory?
The evidence shows that gender dose affect memory. In fact, men and women are equally affected by short-term memory loss. Nevertheless, men can obtain a better long-term memory than women. In the follows, I will explain it more …show more content…
Generally, memory is divided into three processes, which are sensory memory, short-term memory and long-term memory. Sensory memory store is the place in which sensory information is kept for few seconds or less. It happens quickly as well as fast decaying. For example, when you looking at an item and try to remember what it looks like just with a second of observation. Or it is even less than a second when you try to memorize the image that only holds for a very short time. The reason is that the sensory information which come from such as sight, hearing, taste, smell, and touch are being taken in by sensory receptors and processed by the nervous system quickly and cannot be prolonged via rehearsal— which cannot get into another stage memory for recall. There are a series of classic experiments that can explained it more clearly: one is the research participants that were asked to remember rows of letters, however, the researcher flashed on the letters on a screen for just 1/20th of a second. There are less people can really remember what those letters are. The reason is “although that kind information can stores the whole grid, the information fades too quickly for a person to recall everything.” Because those actions just happen in few seconds or even less than 1 second, it is hard to predicate what kind of relationship between gender and memory. “Individuals only holds less one second sensory …show more content…
When people sleep, their body rests and restores its energy levels. A good night sleep means to help you cope with stress, solve problems, or recover from illness. “Sleep is prompted by natural cycles of activity in the brain and consists of two basic states: rapid eye movement (REM) sleep and non-rapid eye movement sleep, which consists of Stages 1 through 4. During sleep, the body cycles between non-REM and REM sleep. Typically, people begin the sleep cycle with a period of non-REM sleep followed by a very short period of REM sleep.” A completed cycle of sleep consists of a progression from stages 1-4(non-REM) before REM sleep is attained, then the cycle starts over again. One sleep cycle costs around 90 minutes. In fact, there is no particular number to show how long that sleep cycle is that people really need. However, it is important for people to process the full stages while sleeping, which means people must enter non-REM then get into REM to ensure a good sleep. “It has been hypothesized that REM (rapid eye movement) sleep has an important role in memory consolidation.” The function of REM sleep "is to remove certain undesirable modes of interaction in networks of cells in the cerebral cortex", which process they characterize as "unlearning". As a result, “those memories which are relevant
