Difficulties in empathy are frequent among children with autism spectrum disorder (ASD), and often considered a core feature of autism. Reduced empathy during the second year of life has been shown to predict subsequent ASD diagnosis. However, links between empathy in the first year and ASD have not yet been investigated. Moreover, prior work focused on empathy for others’ distress but not for others’ joy. To address these gaps, this prospective longitudinal study followed 60 infants (33% girls), 39 at high genetic risk of ASD (siblings of children with ASD) and a matching control group. Infants’ empathic responses to others’ distress and happiness were assessed at ages 6, 9, and 12 months, using simulations by the mother/experimenter and videos of crying and laughing infants. Diagnosis was determined between 18 and 36 months. Infants later diagnosed with ASD showed a reduced empathic response toward a person simulating distress, but not toward a video of a crying peer, and not in response to others’ joy (either in simulation or video). Overall, reduced empathic concern during the first year of life appears to be an early prodromal marker of subsequent ASD. Implications for theory, research, and practice are discussed.

Views regarding children's influence on their environment and their own development have undergone considerable changes over the years. Following Bell's (1968) seminal paper, the notion of children's influence and the view of socialization as a bidirectional process have gradually gained wide acceptance. However, empirical research implementing this theoretical advancement has lagged behind. This Special Section compiles a collection of new empirical works addressing multiple forms of influential child processes, with special attention to their consequences for children's and others’ positive functioning, risk and resilience. By addressing a wide variety of child influences, this Special Section seeks to advance integration of influential child processes into myriad future studies on development and psychopathology and to promote the translation of such work into preventive interventions.

Research on compliance has shown that people can be induced to comply with various requests by using techniques that capitalise on the human tendencies to act consistently and to reciprocate. Thus far this line of research has been applied to interactions between individuals, not to relations between institutions. We argue, however, that similar techniques are applied by courts vis-à-vis the government, the legislature and the public at large, when courts try to secure legitimacy and acceptance of their decisions. We discuss a number of known influence techniques – including ‘foot in the door’, ‘low-balling’, ‘giving a reputation to uphold’ and ‘door in the face’ – and provide examples from Israeli case law of the use of such techniques by courts. This analysis offers new insights that can further the understanding of judicial decision-making processes.
