Hogg and Vaughan (2011, p. 236) define social influence as the 'process whereby attitudes and behaviour are influenced by the real or imagined presence of other people.' They note that this is remarkably similar to one of the classic definitions of social psychology as a whole, which described social psychology as 'the scientific investigation of how the thoughts, feelings and behaviours of individuals are influenced by the actual, imagined or implied presence of others' (Allport, 1954, p. 5).

HI ,

I took this text from a book and in the book another author wrote it, and in the text I already mentioned the name of the author of another book, how this text is referenced, the name on the page of the book is Stephen Gibson.

Thank you!
