AQS/SBQS: Re-adapted Q-sort procedure to study infant differences in Rhesus monkey attachment behaviour

It can be affirmed that the Q-sorting procedure has not be applied until now to depict the individual attachment differences in rheus monkeys (Macaca mulatta). In this research the Q-sort test procedure in which descriptive items (93 for AQS and 101 for SBQS) put in order ranging from Most Descriptive to Least Descriptive both for mothers-infants observed in two subsequent yars (First Year and Second Year), was applied the way that Stony Brook University researchers Everett Waters and Kathleen Deane did for assessing individual difference relationships in children. In this study, the application of thsi new method to monkeys shows significant change between the first Year and the Second Year in some subjects both in AQS or SBQS. Q-sort method can reveal complex details and nuances of behaviour that are impossible to obtain through ordinary ethological observaton.
