Like many other aspirants I was also confused regarding this question which is often repeated in CSS exams.

The recent trends in psychology are mainly
EVOLUTIONARY PSYCHOLOGY
BEHAVIOURAL GENETICS

These are mentioned in Feldman.

Other recent Trends in psychology are

TECNOLOGICAL ADVANCES IN PSYCHOLOGY.


Hope this will be helpful.
