EPQ help?

Hi everyone!
I'm going into Year 12 & have to do the EPQ (with AQA). I'd like my title to be "To what extent is learning a foreign language beneficial to child development?" (something like that). However I know that your EPQ can't be on anything that you're doing as part of your chosen subjects, and I'm doing psychology with AQA which does have cognition and development as an optional part of the specification (so we might do it or we might not). Do you think my title would be okay or is it too close to the topic in the spec?

Thank you so much!

NB: This is what is in the spec about cognition and development:

4.3.4 Cognition and development

Piaget’s theory of cognitive development: schemas, assimilation, accommodation, equilibration, stages of intellectual development. Characteristics of these stages, including object permanence, conservation, egocentrism and class inclusion.

Vygotsky’s theory of cognitive development, including the zone of proximal development and scaffolding.

Baillargeon’s explanation of early infant abilities, including knowledge of the physical world; violation of expectation research.

The development of social cognition: Selman’s levels of perspective-taking; theory of mind, including theory of mind as an explanation for autism; the Sally-Anne study. The role of the mirror neuron system in social cognition.
