References in your text:

For example your initial text could be :
we can associte emotions with decision making and regulation of behaviour.

Adding some references the text would become :
Emotions have been associated with decision making processes through attention shifting, and with regulation of behaviour through vetoeing mechanisms.
However if part 1 is due to Bechara 2004 and part 2 to Toates 2004, you will need to clearly indicate this, by including the reference in your text. Otherwise you are not fully backing up your statements and having these references in your bibliography at the end of your text will not be sufficient.

Therefore the text should read:
Emotions have been associated with decision making processes through attention shifting (Bechara, 2004) , and with regulation of behaviour thanks to vetoeing mechanisms (Toates, 2004).
