I study Psychology and have loads of friends on the Psych and Language Sciences course. If you have any specific questions feel free to PM me. I would suggest unless you have a particular interest in language (or are very good at learning things you're not overly interested) that a straight Psych course might be better, as the language component is pretty strong; they do modules in Grammar and other such things that you'd expect to come more from a Linguistics/English Language degree. But then in 2nd year they do get to do a lang development module where they spend one day a week in a nursery or school - so it does have it's perks :P
