Three experiments assessed the development of children's part and configural (part-relational) processing in object recognition during adolescence. In total, 312 school children aged 7-16 years and 80 adults were tested in 3-alternative forced choice (3-AFC) tasks. They judged the correct appearance of upright and inverted presented familiar animals,(More)
This paper presents a number of autonomous agent simulations as theories of infant attachment. In particular, the simulations model the behaviour of one year old human infants observed in Strange Situation studies. A key question this study is attempting to answer is, for a normal population of infants, why do responses tend to cluster into three groups of(More)

BACKGROUND Previous research has shown that object recognition may develop well into late childhood and adolescence. The present study extends that research and reveals novel differences in holistic and analytic recognition performance in 7-12 year olds compared to that seen in adults. We interpret our data within a hybrid model of object recognition that(More)
Advances in autonomous agent technology have resulted in the potential for implementations of multiple agents to act as psychological theories of complex social and affective phenomena. Simulating attachment behaviours in infancy provides a relatively simple starting point for this type of theory development. The presence of neurophysiological,(More)
The present comment focuses on the distinction between attachment as bond formation and expectations of availability and responsiveness (security) within attachment relationships. We enumerate key components of bonding and functions of carer secure base support. Our analysis has implications for design and suggests that robots are unlikely to serve(More)
This paper reports on an autonomous agent simulation of infant attachment behaviour. The behaviours simulated have been observed in home environments and in a controlled laboratory procedure called the Strange Situation Experiment. The Avoidant, Secure and Ambivalent styles of behaviour seen in these studies are outlined, and then abstracted to their core(More)
In this paper we describe how information processing constructs originating in AI have become part of the Attachment Theory tool kit. We survey the early influence of AI within the theoretical framework that John Bowlby formed as the foundation of Attachment Theory between the 1950s and 1980s. We then review recent work which has built upon Bowlby’s(More)
Attachment Theory describes how humans possess a strong innate predisposition to emotionally attach to familiar people around them who provide physical or emotional security. When infants learn to trust in intimate and enduring relationships they will tend to use their carers to extend their minds. Such cognitive extension is likely to impact mental health(More)
