@SC Ghost: The concept of top-down processing has multiple definitions. Could you clarify what you mean by top-down processing? Are you asking whether children are suggestible? or something much broader? or a little bit broader?

@JeromyAnglim What I meant by top-down processing is the mind's propensity to force the data it receives to match what it is expecting. I do not mean to ask if children are suggestible in actions, but rather if they are suggestible in perception, such as the lyrics example I gave above.

Much evidence suggests **children do not show as much top down processing as adults**. This depends on your definition so I'll state that I generally mean that use of top-down processing appears to increase as a child develops.

Here is the abstract explaining the results of the study [Developmental increase in top-down and bottom-up processing in a phonological task: an effective connectivity, fMRI study.](http://www.ncbi.nlm.nih.gov/pubmed/18702576)

Emphasis mine:

> In older children, top-down control process may selectively enhance the sensitivity of the LTC to bottom-up information from the FG. This may be evident especially in situations that require selective enhancement of task-relevant versus task-irrelevant information. Altogether these results provide a direct evidence for a **developmental increase in top-down control processes in language processing**.

Why is this the case? Generally speaking children need to develop a greater understanding of the world around them before they can put Top-Down and Bottom-Up processing to good use. Piaget framed this in terms of [Schemas](http://www.simplypsychology.org/piaget.html).

Piaget's Stages of Development (which are contraversial mind you) suggest strongly that children start *almost* at a clean slate and build up schemas as they develop and learn. A younger child simply hasn't had the time to build up schemas for every situation, thus they won't always have a relevant schema to process information in a proper top-down fashion.

Note that other studies suggest that older children have an advantage in some tasks because they learn when to *not* apply top down processing. Younger children may simply not "know" the relevance of each processing method as well.
