What is called memory retrieval in cognitive psychology?</h3>
Memory retrieval is the practice of recalling knowledge that has been stored in long-term memory.
Memory retrieval may be classified into two types:
Information is retrieved from memories with the use of the recall method. However, in recognition, the expression of familiar external stimuli gives a cue that the information has been seen before.

Answer: Sex ratio
Explanation: The sex ratio or the gender ratio, as some argue, because according to some scientists these two terms are not interchangeable, is the ratio between the number of men and the number of women in the population. This ratio varies and depends on the type of society, i.e. it depends on economic, social, cultural, biological and technological conditions.
