A considerable body of research has documented the emergence of what appears to be instrumental helping behavior in early childhood. The current study tested the hypothesis that one basic psychological mechanism motivating this behavior is a preference for completing unfinished actions. To test this, a paradigm was implemented in which 2-year-olds (n = 34, 16 female/18 male, mostly White middle-class children) could continue an adult’s action when the adult no longer wanted to complete the action. The results showed that children continued the adult’s actions more often when the goal had been abandoned than when it had been reached (OR = 2.37). This supports the hypothesis that apparent helping behavior in 2-year-olds is motivated by a preference for completing unfinished actions.

Previous research has established that goal tracking emerges early in the first year of life and rapidly becomes increasingly sophisticated. However, it has not yet been shown whether young children continue to update their representations of others’ goals over time. The current study investigates this by probing young children’s (24-30 months old) ability to differentiate between goal directed actions that have been halted because the goal was interrupted, and because the goal was abandoned. To test whether children are sensitive to this distinction, we manipulated the experimenter’s reason for not completing a goal-directed action - his initial goal is either interrupted by an obstacle, or it is abandoned in favour of an alternative. We measure whether children’s helping behaviour is sensitive to the experimenter’s reason for not completing his goal-directed action by recording whether they complete the experimenter’s initial goal or the alternative goal. The results showed that children (n = 24) helped complete the experimenter’s initial goal significantly more often after this goal had been interrupted than after it had been abandoned. These results support the hypothesis that children continue to update their representations of others’ goals over time by the age of two, and specifically that they differentiate between abandoned and interrupted goals.

The dorsal anterior cingulate cortex is a key node in the human salience network. It has been ascribed motor, pain-processing and affective functions. However, the dynamics of information flow in this complex region and how it responds to inputs remain unclear and are difficult to study using non-invasive electrophysiology. The area is targeted by neurosurgery to treat neuropathic pain. During deep brain stimulation surgery, we recorded local field potentials from this region in humans during a decision-making task requiring motor output. We investigated the spatial and temporal distribution of information flow within the dACC. We demonstrate the existence of a distributed network within the anterior cingulate cortex where discrete nodes demonstrate directed communication following inputs. We show that this network anticipates and responds to the valence of feedback to actions. We further show that these network dynamics adapt following learning. Our results provide evidence for the integration of learning and the response to feedback in a key cognitive region.

This book argues that Levi Gersonides articulates a unique model of virtue ethics among medieval Jewish thinkers. Gersonides is recognized by scholars as one of the most innovative Jewish philosophers of the medieval period. His first model of virtue is a response to the seemingly capricious forces of luck through training in endeavor, diligence, and cunning aimed at physical self-preservation. His second model of virtue is altruistic in nature. It is based on the human imitation of God as creator of the laws of the universe for no self-interested benefit, leading humans to imitate God through the virtues of loving-kindness, grace, and beneficence. Both these models are amplified through the institutions of the kingship and the priesthood, which serve to actualize physical preservation and beneficence on a larger scale, amounting to recognition of the political necessity for a division of powers.
