Parsing Heuristic and Forward Search in First‐Graders' Game‐Play Behavior

Seventy‐three children between 6 and 7 years of age were presented with a problem having ambiguous subgoal ordering. Performance in this task showed reliable fingerprints: (a) a non‐monotonic dependence of performance as a function of the distance between the beginning and the end‐states of the problem, (b) very high levels of performance when the first move was correct, and (c) states in which accuracy of the first move was significantly below chance. These features are consistent with a non‐Markov planning agent, with an inherently inertial decision process, and that uses heuristics and partial problem knowledge to plan its actions. We applied a statistical framework to fit and test the quality of a proposed planning model (Monte Carlo Tree Search). Our framework allows us to parse out independent contributions to problem‐solving based on the construction of the value function and on general mechanisms of the search process in the tree of solutions. We show that the latter are correlated with children's performance on an independent measure of planning, while the former is highly domain specific.     

Two Theories of Just War

As it is traditionally conceived, Just War Theory is not well suited for dealing with nation vs non-nation wars. It thus makes sense to create a second Just War Theory to deal with these wars. This article explores the differences and similarities between the two theories.

A Recess Evaluation with the Players: Taking Steps Toward Participatory Action Research

This qualitative study, part of a Canadian national study of fathers’ involvement, opened up First Nations and Métis fathering as a new area of inquiry. Conversational interviews with 80 Indigenous fathers illuminated the socio-historical conditions that have shaped Indigenous men’s experiences of learning to be a father and becoming a man in the context of changing gender relationships and the regeneration of circles of care. Indigenous fathers’ experiences unfold in a socio-historical context fraught with difficulties. However, the study findings suggest cultural strengths and sources of resilience unseen in research and community programs driven by Euro-western perspectives. This research can inform efforts to reduce systemic barriers and reconstitute positive father involvement following disrupted intergenerational transmission of fathering in Canada and elsewhere.     

Drawing as a means of communication at the initial interview with children with cancer

Cancer is always associated with distress and fear. In working with children who have cancer, a trusting relationship and meaningful dialogue often cannot be established by talking on its own. Drawings may offer an opportunity for children to express their feelings without giving up resistance completely. This paper summarizes the aims of the first interview with an ill child, one of its main purposes being the evaluation of the children's and their family's resources to cope with the strains of the illness. The meaning of drawings in this process is discussed in two case reports.     

Normal face-based judgements of social characteristics despite severely impaired holistic face processing

Initial evidence indicates that face-based judgements of socially relevant characteristics such as people's trustworthiness or attractiveness are linked to the configural/holistic processing of facial cues. What remains a matter of debate, however, is whether such processing is actually necessary for normal social judgements to occur and whether it resembles the type of integrative processing as required for facial identification. To address these issues, we asked a well-characterized case of acquired prosopagnosia (PS) with a marked deficit in holistic processing for face identity to rate a series of faces on several dimensions of social relevance. PS provided ratings within the normal range for most of the social characteristics probed (i.e., aggression, attractiveness, confidence, intelligence, sociability, trustworthiness). Her evaluations deviated from those of healthy controls only when facial dominance was concerned. Taken together, these data demonstrate that the inability to integrate facial information during face individuation does not necessarily translate into a generalized deficit to evaluate faces on social dimensions.     

JUST WAR THEORY,HUMANITARIAN INTERVENTION,AND THE NEED FOR A DEMOCRATIC FEDERATION

The primary purpose of government is to secure public goods that cannot be achieved by free markets. The Coordination Principle tells us to consolidate sovereign power in a single institution to overcome collective action problems that otherwise prevent secure provision of the relevant public goods. There are several public goods that require such coordination at the global level, chief among them being basic human rights. The claim that human rights require global coordination is supported in three main steps. First, I consider Pogge's and Habermas's analyses as alternatives to Hobbesian conceptions of justice. Second, I consider the core conventions of international law, which are in tension with the primacy of state sovereignty in the UN system. Third, I argue that the just war tradition does not limit just causes for war to self‐defense; it supports saving innocent third parties from crimes against humanity as a just reason for war. While classical authors focused less on this issue, the point is especially clear in twentieth‐century just war theories, such as those offered by the American Catholic bishops, Jean Elshtain, Brian Orend, and Michael Walzer. Against Walzer, I argue that we add intractable military tyranny to the list of horrors meriting intervention if other ad bellum conditions are met. But these results require us to reexamine the “just authority” of first resort to govern such interventions. The Coordination Principle implies that we should create a transnational federation with consolidated powers in place of a treaty organization requiring near‐unanimity. But to be legitimate, such a global institution must also be directly answerable to the citizens of its member states. While the UN Security Council is inadequate on both counts, a federation of democracies with a directly elected executive and legislature could meet both conditions.     

“Seeing Rain”: Integrating phenomenological and Bayesian predictive coding approaches to visual hallucinations and self-disturbances (Ichstörungen) in schizophrenia

We present a schizophrenia patient who reports “seeing rain” with attendant somatosensory features which separate him from his surroundings. Because visual/multimodal hallucinations are understudied in schizophrenia, we examine a case history to determine the role of these hallucinations in self-disturbances (Ichstörungen). Developed by the early Heidelberg School, self-disturbances comprise two components: 1. The self experiences its own automatic processing as alien to self in a split-off, “doubled-I.” 2. In “I-paralysis,” the disruption to automatic processing is now outside the self in omnipotent agents. Self-disturbances (as indicated by visual/multimodal hallucinations) involve impairment in the ability to predict moment-to-moment experiences in the ongoing perception-action cycle. The phenomenological approach to subjective experience of self-disturbances complements efforts to model psychosis using the computational framework of hierarchical predictive coding. We conclude that self-disturbances play an adaptive, compensatory role following the uncoupling of perception and action, and possibly, other low-level perceptual anomalies.     

Le consentement du patient aux actes de secours lors d’interventions extrahospitalières

The acquirement of a person's consent to the medical care that is proposed to a patient is an absolute basic principle in rescue health care. This is mandatory for first arrival rescuers ; especially since their actions are, in view of the French Emergency Medical Service call centers, considered as being a medical act. The basic principle of consent to first medical care hence imposes itself as a humanitarian act as well as preventing any potential litigation. Nevertheless there are numerous situations where the management of the consent of the person in need of non-medical assistance will present difficulties. It is the necessary to analyze how the rescue health care system can manage and limit the risks s linked to the different situations when treatment is refused by the person in need of such help ; and this so as to respect the individual's dignity whilst not abandoning the needed health care. A collaboration between rescue personnel and the call center coordinating medical doctor is then mandatory especially when no consent is obtained. This will enable the detection of hypotheses where the individual's lucidity is altered and implement proportionately required and helpful measures. It will also equally enable the transmission of efficient information to the patient, in relation to the matter of patient consent and to ensure that the patient is aware of the consequence of his or her decision and that this decision was fully expressed. It would hence be deemed useful that the referenced work frame and recommendations, pertaining to the emergency rescue of a person, established by the General Management of Public Safety and Crisis Management detail more in detail these difficult and delicate situations so as to ensure that rescue personnel can better anticipate them. To conclude were commend a formalization of procedures that could be implemented in situations where a patient that has full mental capacities refuses the proposed health care, and we give the advantages of such a procedure be discussed.     

Through babies’ eyes: Practical and theoretical considerations of using wearable technology to measure parent–infant behaviour from the mothers’ and infants’ view points

AimsTo explore the utility of first-person viewpoint cameras at home, for recording mother and infant behaviour, and for reducing problems associated with participant reactivity, which represent a fundamental bias in observational research.MethodsWe compared footage recording the same play interactions from a traditional third-person point of view (3rd PC) and using cameras worn on headbands (first-person cameras [1st PCs]) to record first-person points of view of mother and infant simultaneously. In addition, we left the dyads alone with the 1st PCs for a number of days to record natural mother–child behaviour at home. Fifteen mothers with infants (3–12 months of age) provided a total of 14 h of footage at home alone with the 1st PCs.ResultsCodings of maternal behaviour from footage of the same scenario captured from 1st PCs and 3rd PCs showed high concordance (kappa >0.8). Footage captured by the 1st PCs also showed strong inter-rater reliability (kappa = 0.9). Data from 1st PCs during sessions recorded alone at home captured more ‘negative’ maternal behaviours per min than observations using 1st PCs whilst a researcher was present (mean difference = 0.90 (95% CI 0.5–1.2, p < 0.001 representing 1.5 SDs).Conclusion1st PCs offer a number of practical advantages and can reliably record maternal and infant behaviour. This approach can also record a higher frequency of less socially desirable maternal behaviours. It is unclear whether this difference is due to lack of need of the presence of researcher or the increased duration of recordings. This finding is potentially important for research questions aiming to capture more ecologically valid behaviours and reduce demand characteristics.
