The word "imagological" doesn't exist, according to Oxford English Dictionary but I'm sure it's just the adj. of "imago", which is:
1. a. Entom. The final and perfect stage or form of an insect after it has undergone all its metamorphoses; the ‘perfect insect’.
b. transf. The perfect stage of other animals that undergo a metamorphosis.
2. Psychoanalysis. A subjective image of someone (esp. a parent) which a person has subconsciously formed and which continues to influence his attitudes and behaviour. So father-imago, mother-imago.
