I believe the answer is:

jungles

I'm a little stuck... Click here to teach me more about this clue!

'places' is the definition.
(I know this)

'swiss psychologist joining the french' is the wordplay.
'swiss psychologist' becomes 'jung' (I've seen this in another clue).
'joining' is a charade indicator (letters next to each other).
'the french' becomes 'les' (plural form of 'the' in French).
'jung'+'les'='JUNGLES'

'in wild' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?

I've seen this clue in the Evening Standard.
