Preschoolers' retrospective and prospective judgements of immanent justice following distributive actions.

Prior research provided evidence for retrospective and prospective judgements of immanent justice in adults, but the developmental origins of judgements of immanent justice remain unknown. Both retrospective and prospective judgements were investigated in preschool age, using explicit and implicit measures. In Experiment 1, 2.5- and 4-year-olds were first shown events in which one agent distributed resources fairly or unfairly, and then they saw test events in which both distributors were damaged by a misfortune. Later, they were presented with a verbal task, in which they had to respond to two questions on evaluation of the deservingness, by using explicit measures. All children were likely to approve of deserved outcomes when deeds and outcomes were congruent (i.e., unfair distributor-misfortune), and only older ones were likely to disapprove when they were incongruent (i.e., fair distributor-misfortune). In Experiment 2, 4-year-olds after seeing familiarization events of Experiment 1, were presented with two verbal questions to explore prospective judgements of immanent justice, by using explicit measures. In Experiment 3, 4-year-olds were first shown familiarization events of Experiment 1 and listened to respective narratives, then before the outcome was revealed they were assessed with a reaching task to investigate prospective judgements of immanent justice, by using implicit measures. Children reached the image depicting a bad outcome for the unfair distributor, and that illustrated a good outcome for the fair distributor. The results of the last two experiments demonstrated a fine ability to make prospective judgements at 4 years of life, and found that they were to be more prone to apply immanent justice reasoning to positive outcomes following good actions. Taken together, these results provide new evidence for preschoolers' retrospective and prospective judgements of immanent justice.

Reflective functioning and dissociative experiences: A comparison study between adolescents at "high-risk" of psychosis and healthy controls.

Background: Despite the established contribution to psychological well-being in young subjects, the investigation of reflective functioning and dissociative experiences in help-seekers adolescents still appears an unmet need. Objective: The study aimed to assess reflective functioning and dissociative symptoms in help-seekers adolescents, and compare them to gender-matched healthy controls. Methods: The Reflecting Functioning Questionnaire (RFQ) was used to investigate mentalizing; the Adolescent Dissociative Experience Scale (A-DES) was used to explore dissociative symptoms. Results: The study involved 102 adolescents (mean age 18.06 ± 1.78 years), split into "help-seekers" (N= 51; mean age 19 ± 1.98 years) and healthy controls (N= 51; mean age 17.12 ± 0.84). "Help-seekers" adolescents showed lower RFQ-certainty scores (mean 3.39 ± 2.47), compared to healthy controls (mean 6.73 ± 5.01). Furthermore, "help-seekers" adolescents reported higher scores on RFQ-uncertainty (mean 7.73 ± 4.38), compared to healthy controls (mean 5.14 ± 4.17), which indicates a greater lack of knowledge about mental states (hypomentalizing). Eventually, "help-seekers" adolescents showed significantly worse dissociative symptoms (A-DES total mean score 3.49 ± 2.04), compared to healthy controls (A-DES total mean score 2.06 ± 1.43). Conclusion: The importance of an assessment in early adolescence denotes a topic of increasing concern, in order to identify failures in reflective functioning and the onset of dissociative experiences among help-seekers adolescents, toward the implementation of tailored psychological interventions.

Evaluations of pro-environmental behaviors by 7-month-old infants.

Environmental morality is the foundation of a sustainable future, yet its ontogenetic origin remains unknown. In the present study, we asked whether 7-month-olds have a sense of 'environmental morality'. Infants' evaluations of two pro-environmental actions were assessed in both visual and reaching preferential tasks. In Experiment 1, the overt behavior of protecting (i.e., collecting artificial objects spread on a lawn) was compared with the action of harming the environment (i.e., by disregarding the objects). In Experiment 2, the covert behavior of protecting the environment (i.e., maintaining artificial objects inside a container) was compared with the action of harming the environment (i.e., littering the artificial objects on a lawn). The results showed infants' reaching preference for the agent who performed overt pro-environmental actions (Experiment 1), and no preference for the agent who performed covert pro-environmental actions (Experiment 2). These findings reveal a rudimentary ecological sense and suggest that infants require different abilities to evaluate overt impact-oriented and covert intend-oriented pro-environmental behaviors.

Intention-based evaluations of distributive actions by 4-month-olds.

Four-month-olds' ability to consider the intentions of agents performing distributive actions was investigated in four experiments, using the Violation of Expectation paradigm (VoE) (Experiments 1-3) and the Preferential Looking paradigm (Experiment 4). In Experiment 1, infants were presented with two events showing two types of failed attempts to perform a distribution. In an attempt to distribute fairly, the distributor first tried to reach one of the recipients to deliver an apple, he failed, and then attempted to reach the other recipient to deliver a second apple and also failed. In an attempt to distribute unfairly, a different distributor tried unsuccessfully to bring resources always to the same recipient. Infants looked reliably longer at failed fair distribution events, suggesting that they did not just react to the actions outcomes and they attended to agents' intentions. Experiments 2 and 3 assessed alternative explanations based on perceptual factors or affiliative behaviors. In Experiment 4, during the test trials, infants were shown both distributors simultaneously and they preferred to look at the fair rather than at the unfair distributor. Overall, these findings reveal an early ability to take into account distributors' intentions and a preference for watching agents that tried to distribute resources fairly.

Preverbal infants' reactions to third-party punishments and rewards delivered toward fair and unfair agents.

Rewarding individuals who distribute resources fairly and punishing those who distribute resources unfairly may be very important actions for fostering cooperation. This study investigated whether 9-month-olds have some expectations concerning punishments and rewards that follow distributive actions. Infants were shown simple animations and were tested using the violation-of-expectation paradigm. In Experiment 1, we found that infants looked longer when they saw a bystander delivering a corporal punishment to a 'fair distributor,' who distributed some windfall resources equally to the possible recipients, rather than to an 'unfair distributor,' who distributed the resources unequally. This pattern of looking times was reversed when, in Experiment 2, punishments were replaced with rewards. These findings suggest an early emergence of expectations about punishing and rewarding actions in third-party contexts, and they help to evaluate competing claims about the origins of a sense of fairness.

Failures in Reflective Functioning, Dissociative Experiences, and Eating Disorder: a Study On a Sample of Italian Adolescents.

Although impairments in mentalizing and dissociation have been linked to the onset of eating disorders, there is still a paucity of studies investigating their relationships among adolescents. This study aimed at investigating the role of failures in reflective functioning and dissociation in predicting the risk of eating disorders during adolescence. The Eating Disorder Inventory-3 (EDI-3), the Reflective Functioning Questionnaire (RFQ), and the Adolescent Dissociative Experiences Scale (A-DES) were administered to a sample of 427 adolescents between 13 and 20 years old. Results of correlational analysis showed that the risk of eating disorders was positively correlated with uncertainty about mental states. Eating disorder risk was also inversely correlated with certainty about mental states. Dissociation scores and its domain scores were all positively related to the risk of eating disorders. Results of regression analysis displayed that uncertainty about mental states and dissociation were statistically significant predictors of an increased risk of eating disorders. Gender and BMI were also significant predictors in the final model, which explained 24% of the variance. Regarding the specific dissociative domains, findings indicate that the depersonalization/derealization factor was the only significant predictor for the risk of eating disorder. The present study points out that uncertainty about mental states and dissociation could play a relevant role in increasing the risk of eating disorders during adolescence.

Infants' preferences for approachers over repulsers shift between 4 and 8 months of age.

Despite its adaptive value for social life, the emergence and the development of the ability to detect agents that cause aversive interactions and distinguish them from potentially affiliative agents (approachers) has not been investigated. We presented infants with a simple interaction involving two agents: one of them (the "repulser") moved toward and pushed the other (the "approacher") which reacted by simply moving toward the repulser without contacting it. We found that 8-month-olds (N = 28) looked longer at the approacher than at the repulser (Experiment 1), whereas 4-month-olds (N = 30) exhibited no preference (Experiment 2). To control for low-level cues (such as the preference for the agent that moved after the contact), two new groups of 4- and 8-month-old infants were presented with a series of interactions in which the agents inverted their social roles. Older infants (N = 30) manifested no preference for either agent (Experiment 3), while younger infants (N = 30) looked longer at the first agent to move (Experiment 4). Our results indicated that 8-month-olds' preferences for the approacher over the repulser depended on social information and were finely tuned to agents that display prosocial rather than antisocial behavior. We discuss these findings in light of the development and adaptive value of the ability to negatively evaluate repulsers, to avoid choosing them as partners.

Infants' intention-based evaluations of distributive actions.

Recent research revealed that infants attend to agents' intentions when they evaluate helping actions. The current study investigated whether infants also consider agents' intentions when they evaluate distributive actions. In Experiment 1, 9-month-old infants were first shown two failed attempts to perform a distribution. In the "failed equal distribution," the distributor first tried to reach one of the recipients to deliver an apple, failed, and then attempted to reach the other possible recipient to deliver a different apple and also failed. In the "failed unequal distribution," a different distributor always tried unsuccessfully to reach the same beneficiary. Then, in the test phase, infants were presented with the two distributors side by side, and infants' spontaneous preferential looking and reaching actions were recorded. We found a reliable preference for the equal distributor in both the visual and manual responses. Experiments 2 and 3 helped to rule out alternative explanations based on perceptual cues and affiliative biases. Overall, these findings suggest that infants' ability to evaluate distributive actions relies not only on the outcomes but also on the distributors' intentions.

Improving the generalizability of infant psychological research: The ManyBabies model.

Yarkoni's analysis clearly articulates a number of concerns limiting the generalizability and explanatory power of psychological findings, many of which are compounded in infancy research. ManyBabies addresses these concerns via a radically collaborative, large-scale and open approach to research that is grounded in theory-building, committed to diversification, and focused on understanding sources of variation.

Toddlers' expectations of corporal third-party punishments against the non-defender puppet.

Recent research has demonstrated that toddlers expect individuals to approach and reward those who defend a victim from an aggressor rather than those who refuse to do so. This work focused on toddlers' expectations of corporal third-party punishments trought various actions, such as hitting with a stick or repelling someone who refused to defend a social partner following aggression. Using a violation of expectation paradigm (VoE), three experiments were carried out to investigate whether 21-month-olds expect others to apply different kinds of corporal punishments against the non-defender puppet (expected event) rather than the defender puppet (unexpected event), showing a bystander hitting with a stick (Experiment 1) or pushing strongly (Experiment 3) each of the two puppets. In both experiments, toddlers showed to be surprised whent the saw the bystander punish by hitting or pushing the defender puppet rather the non-defender puppet. In a control experiment displaying a non-social condition (Experiment 2), in which the victim puppets were replaced by two inert boxes, toddlers showed no expectation. These results uncovered that toddlers expect others to engage in different corporal punishments toward those who refuse to defend a social partner from an aggressor, by revealing that these expectations are not specific to a single type of punishment. The findings raise questions about the development of corporal third-party punishments, and have implications for the theory on ontogenetic processes underlying sociomoral development.

Toddlers' expectations of third-party punishments and rewards following an act of aggression.

Rewarding someone who defends the victim of an unjust aggression and punishing someone who chose not to defend her may be very important acts of reciprocation in social life. This study investigates whether 21-month-olds have some expectations concerning such punishing and rewarding actions. Infants were shown simple puppet shows and were tested using the violation-of-expectation paradigm. In Experiment 1, we found that infants looked longer when they saw a bystander puppet punishing the puppet who defended the victim rather than the puppet who did not defend her. This pattern of looking times was reversed when the punishing action was replaced with a rewarding action (Experiment 2). These findings reveal early-emerging expectations about punitive and reward motivations in third-party contexts, and provide some support for theoretical claims about the hardwiring of the human mind for cooperation and prosociality.

How do toddlers evaluate defensive actions toward third parties?

Defensive behavior is a central aspect of social life and provides benefits to the self and others. Recent evidence reveals that infants evaluate third parties' prosocial and antisocial actions. Three experiments were carried out to assess toddlers' reactions to defensive and non-defensive events (N = 54). In two experiments, infants' looking times and manual choices provided converging evidence that 20-month-olds understand and evaluate defensive actions, by showing that they prefer the defensive puppet over the non-defensive puppet and that they reason on the bystander puppet's disposition. In the third experiment, toddlers rewarded the defensive puppet rather than the non-defensive puppet, revealing how their evaluations guided awarding behaviors of defensive actions toward the third party. The results support the developmental stability and provide evidence of a rich and well-organized prosociality that before the second year of life proves to be based on some moral principles and linked with a sophisticated psychological reasoning. The findings shed light on the claims that human capacities for the social evaluation of defensive behaviors toward third parties are rooted in evolved cooperative systems.

Giving and taking: representational building blocks of active resource-transfer events in human infants.

Active resource transfer is a pervasive and distinctive feature of human sociality. We hypothesized that humans possess an action schema of giving specific for representing social interactions based on material exchange, and specified the set of necessary assumptions about giving events that this action schema should be equipped with. We tested this proposal by investigating how 12-month-old infants interpret abstract resource-transfer events. Across eight looking-time studies using a violation-of-expectation paradigm we found that infants were able to distinguish between kinematically identical giving and taking actions. Despite the surface similarity between these two actions, only giving was represented as an object-mediated social interaction. While we found no evidence that infants expected the target of a giving or taking action to reciprocate, the present results suggest that infants interpret giving as an inherently social action, which they can possibly use to map social relations via observing resource-transfer episodes.

Belief attribution in deaf and hearing infants.

Based on anticipatory looking and reactions to violations of expected events, infants have been credited with 'theory of mind' (ToM) knowledge that a person's search behaviour for an object will be guided by true or false beliefs about the object's location. However, little is known about the preconditions for looking patterns consistent with belief attribution in infants. In this study, we compared the performance of 17- to 26-month-olds on anticipatory looking in ToM tasks. The infants were either hearing or were deaf from hearing families and thus delayed in communicative experience gained from access to language and conversational input. Hearing infants significantly outperformed their deaf counterparts in anticipating the search actions of a cartoon character that held a false belief about a target-object location. By contrast, the performance of the two groups in a true belief condition did not differ significantly. These findings suggest for the first time that access to language and conversational input contributes to early ToM reasoning.

Where will the triangle look for it? Attributing false beliefs to a geometric shape at 17 months.

Prior research on implicit mind-reading skills has focussed on how infants anticipate other persons' actions. This study investigated whether 11- and 17-month-olds spontaneously attribute false beliefs (FB) even to a simple animated geometric shape. Infants were shown a triangle chasing a disk through a tunnel. Using an eye-tracker, we found that 17-month-olds in a change-of-location true belief (TB) task anticipated that the triangle would search for the disk in the correct place while in a FB test they anticipated that it would search for it in the wrong, belief congruent place. These results suggest that 17-month-olds' psychological-reasoning system is applied to the actions of unfamiliar agents and it is employed to anticipate agents' actions even in the absence of any morphological features that are typical of natural agents. These findings provide support for theoretical accounts that emphasize continuity in the development of theory of mind core concepts and belief reasoning skills.

The developmental roots of fairness: infants' reactions to equal and unequal distributions of resources.

The problem of how to distribute available resources among members of a group is a central aspect of social life. Adults react negatively to inequitable distributions and several studies have reported negative reactions to inequity also in non-human primates and dogs. We report two experiments on infants' reactions to equal and unequal distributions. In two experiments, infants' looking times and manual choices provide, for the first time, converging evidence suggesting that infants aged 12 to 18 months (mean age 16 months) attend to the outcomes of distributive actions to evaluate agents' actions and to reason about agents' dispositions. The results provide support for recent theoretical proposals on the developmental roots of social evaluation skills and a sense of fairness.

Inferential reasoning: comparison of patients with schizophrenia and patients with traumatic brain injury.

We investigated the cognitive processes underlying inferential reasoning, comparing performance of patients suffering from schizophrenia with that of patients with brain injury in an attempt to understand the nature of the social impairments in schizophrenia. Inferential reasoning on mental and physical states and second-order false belief attribution were assessed in healthy controls, in patients with schizophrenia and in brain trauma patients with predominantly ventromedial prefrontal cortex or dosolateral prefrontal cortex lesions. Our finding that ventromedial prefrontal areas are involved in general inferential reasoning casts further light on the neural structures implicated in socio-cognitive impairments in schizophrenia.

Theory of Mind in patients with ventromedial or dorsolateral prefrontal lesions following traumatic brain injury.

PRIMARY OBJECTIVE: Previous studies on patients with traumatic brain injuries (TBI) and diffuse brain damages have reported selective deficits in mental states reasoning or 'Theory of Mind' (ToM). The goal of the current study is to investigate the fundamental role of the prefrontal cortex in two ToM components: inferential reasoning and social perception. RESEARCH DESIGN: Selective cognitive impairments following a TBI provide crucial evidence for assessing competing models of specific aspects of the cognitive system. METHOD AND PROCEDURE: This study compared the performance of patients with predominantly focal lesions in the ventromedial (n = 11) or dorsolateral prefrontal cortex (n = 7) with matched controls (n = 20). All subjects performed two ToM tasks: the Eyes Test and the Faux-pas Test. RESULTS: It was found that both groups of patients performed equally poorly on the Eyes Test, but only patients with predominantly lesions in the ventromedial cortex performed poorly on the Faux-pas test. The group effects on ToM tasks could not be reduced to differences in the global severity of brain injuries. CONCLUSIONS: These results provide evidence supporting some current models of the fractionation of the mind-reading system and support the claim that the ventromedial cortex plays a fundamental role in inferential reasoning.
