Memory Test
Memory provides humans with the ability to learn, to modify their behaviour in the light of experience and hence to reduce their uncertainty about the world. This is clearly an important behavioural adaptation. Indeed, humans exhibit many forms of learning and memory, ranging all the way from gradual weakening (habituation) or strengthening (sensitization) of simple reflex actions, to conscious recollection of personal experiences.
We might be able to remember a telephone message for the few seconds it takes to write it down. But we can also remember things over very long periods of time. For example, adults may still remember some of the things they were taught at school — both general abilities, such as how to add numbers together, and specific things. Additionally, we can also remember (though unconsciously) many of the skills attained through life, such as how to ride a bicycle or play the piano. There are many different ways in which humans and other animals remember things. It follows that memory cannot be conceptualized simply and that there are likely to be a variety of different, interacting memory systems.
