What Is Memory?

Webster’s Dictionary defines memory as “a particular act of recall or recollection.” Simple enough, right? 
However, when examining the positive and negative effects of cannabis on memory, it’s important to delineate several different memory subtypes. This is useful because it appears that there’s quite a bit of divergence in effects depending on which memory subtype is being tested.
Prospective memory refers to a person’s ability to remember to perform a certain action at a specific time in the future.
Temporal order memory involves remembering the correct order in which a series of events occurred.
False memories are inaccurate recollections of past events. 
Free recall is a type of common memory test where information is given to a participant who later has to restate the data. It’s important to note that the ability to remember the order in which the information was shared is not an aspect of free-recall testing. 
Source memory refers to a person’s capacity to recall the origin of their memories or knowledge. For example, if you remember how to spell “receive” correctly because a teacher admonished you in front of your peers when you misspelled that word.
Working memory is an aspect of short-term memory that involves a person’s ability to remember things while occupied with a task. 
Now, with these definitions established, let’s proceed to an analysis of the latest research on how cannabis affects memory.
