The Carnival continued its evolution in small/unimportant towns out of view of the rulers. The result was the uninterrupted celebration of Carnival festivals in Barranquilla (see Barranquilla's Carnival) now recognized as one of the Masterpieces of the Oral and Intangible Heritage of Humanity. The Barranquilla Carnival includes several parades on Friday and Saturday nights beginning on 11 January and ending with a six-day non-stop festival, beginning the Wednesday prior to Ash Wednesday and ending Tuesday midnight. Other celebrations occur in villages along the lower Magdalena River in northern Colombia, and in Pasto, Narino (see Blacks and Whites' Carnival) in the south of the country. In the early 20th century, attempts to introduce Carnival in Bogota were rejected by the government. The Bogota Carnival was renewed in the 21st century.
The uninterrupted celebration of Carnival festivals in Barranquilla is now recognized as what?
A: one of the Masterpieces of the Oral and Intangible Heritage of Humanity

Infants do not have the language ability to report on their memories and so verbal reports cannot be used to assess very young children's memory. Throughout the years, however, researchers have adapted and developed a number of measures for assessing both infants' recognition memory and their recall memory. Habituation and operant conditioning techniques have been used to assess infants' recognition memory and the deferred and elicited imitation techniques have been used to assess infants' recall memory.
How can a researcher study a childs memory?
A:
elicited imitation techniques
