The Development of Global and Local Processing: A Comparison of Children to Adults

In light of the adult model of a hemispheric asymmetry of global and local processing, we compared children (M _age = 8.4 years) to adults in a global-local reaction time (RT) paradigm. Hierarchical designs (large shapes made of small shapes) were presented randomly to each visual field, and participants were instructed to identify either the global or the local level in each of two blocks. We obtained evidence of a global-local processing asymmetry, with stronger effects for children than for adults. In both children and adults, responses were faster and more accurate for global identification in the right hemisphere and for local identification in the left hemisphere. Similarly, a significant asymmetry of global and local interference was obtained in children but not in adults. Interference reflects the RT cost of conflicting information at the nonattended level. For example, local interference indicates the degree to which inconsistency at the local level slows global identification. Stronger evidence for lateralized processing in children is discussed within the framework of increasing interhemispheric transfer. That is, as interhemispheric transfer increases, cost of presentation to the nonpreferred hemisphere (e.g., local identification in the right hemisphere) is reduced.     

Unravelling Crime Series Patterns amongst Serial Sex Offenders: Duration,Frequency, and Environmental Consistency

Crime linkage and the investigation of behavioural consistency amongst serial offenders has been a flourishing field of research over the past decade or so, especially with respect to serial sex offenders. The emerging research in this field has often portrayed serial sex offenders as a single, distinct, and homogeneous group. Such an assumption, however, has never been empirically examined. Using a criminal career approach and a sample of 72 serial sex offenders who have committed a total of 361 sexual assaults on stranger victims, the current study aims to examine and describe subgroups of crime series patterns amongst serial sex offenders in terms of duration and frequency of offending. The level of environmental consistency display (i.e. offender's choice of crime location and characteristics of the crime site selected) across subgroups of crime series patterns is also examined. Study findings suggest the presence and heterogeneity of crime series patterns amongst serial sex offenders, advocating for the consideration of subgroups of crime series patterns when studying serial sex offenders. Moreover, the offenders' level of environmental consistency varies across the different crime series patterns identified, allowing for the identification of subgroups of offenders showing a higher or lower level of environmental consistency.

A model‐based approach to limb apraxia in Alzheimer's disease

Limb apraxia is a neurological deficit characterized by an inability to pantomime and/or imitate gestures, which can result from neurodegenerative disorders such as Alzheimer's disease (AD). The major goal of the study was to describe comprehensively the apraxia deficits observed in AD patients and to relate those deficits to general cognitive status, measures of daily activity, and other neuropsychological measures. Limb apraxia was assessed on a variety of conceptual and gesture production tasks in 30 AD patients. As a group, AD patients were impaired across gesture production tasks: of note was the greater impairment in imitation, as opposed to pantomime, which was especially pronounced when patients were imitating with a delay. Imitation performance was best predicted by measures of visuospatial processing, while imitation with delay was best predicted by measures of working memory. In addition, pantomime in response to pictures of tools was less accurate than Pantomime to Verbal Command and holding the tool during performance did not decrease the participants' impairment, while introducing a verbal cue during imitation increased the severity of deficits. Furthermore, investigation into patterns of deficits clearly demonstrated that the nature of limb apraxia deficits observed in AD can be quite heterogeneous and that dissociations between the conceptual and the production system exist. Finally, we also report on significant correlations between general cognitive status and limb apraxia.     

Reasoning about make-believe and hypothetical suppositions: Towards a theory of belief-contravening reasoning

The present study explores how suppositions which conflict with accepted beliefs are represented and reasoned about. Two studies test the predictions regarding the nature and developmental changes in children's ability to represent and reason about hypothetical or make-believe suppositions which violate their everyday knowledge and beliefs. In Study 1, 46 4th- and 5th-graders were introduced to a hand puppet, Freddy, who made claims inconsistent with generally accepted beliefs (e.g., “all dogs meow”) because he was pretending (Make-Believe Condition) or believed them (Hypothetical Condition). Participants were asked to think like Freddy and judge whether a conclusion (“There's a dog; does it meow?”) follows logically from the claim. In Study 2, 40 kindergarten (6-year-olds), 3rd–4th grade (10-year-olds), and college students were asked to represent belief contravening make-believe (pretend in a make-believe world that dogs meow) and hypothetical (imagine what the real world would be like if dogs meow) premises, evaluate conclusions of the premises (Rover is a dog, does Rover meow?) and make judgments about the attributes (growl, wag tail, purr, and eat mice) of the entity (a meowing dog) they created. The prediction that it would be easier to represent and reason from belief-contravening suppositions in the Make-Believe than Hypothetical conditions was confirmed in each study, although the two forms of reasoning were directly correlated (Study 2). The results were discussed in terms of the similarities (compartmentalization and integration) and differences (reconciliation) of processes involved in fancifully (make-believe) or seriously (hypothetical) representing and reasoning about belief-contravening suppositions.     

Beyond Critique: Just War as Theological Political Theology

This article takes up a charge often directed to neo-Augustinians by neo-Anabaptists that their defense of just war lacks adequate theological foundations. It is the case that most contemporary just war advocates, even within Christian ethics, no longer embed their accounts within a distinctively theological context, let alone a robust appeal to a doctrine of God or divine providence attentive to the divine One who really entered history, suffered defeat, and conquered death. This development can be seen as a form of self-denial for the sake of consensus and casuistry. In so doing, however, they confirm the claim of many Christian pacifists that just war reasoning betrays the radical creativity of Christian virtue in the name of some external (often duty-based) notion of responsibility and retributive justice. My project differs. It taps into resurgent interest in political theology as a way to remedy this neglect at least a little. I focus on two aspects of political theology that bear primarily on the relation of the temporal and the eternal: providence and suffering. They are rooted in fundamental theology, guided by the memory of being grafted as strangers into the God of Israel, the same God who showed compassion for Esau even while blessing Jacob. Just war tradition is an act of compassion rooted in providence and the inevitable suffering faced in history. The point is to re-theologize a living tradition that generations of the ecumenical church bequeathed to us as an exercise of their Christian imagination within their historical contexts where they took all of history seriously as God’s time. Wary of idolatry, we should strive for more than critique or a disappointing choice between Christendom or Church as the only theological word to the nations.     

Reasons or rationalizations: The role of principles in the moral dumbfounding paradigm

Moral dumbfounding occurs when people maintain a moral judgment even though they cannot provide reasons for it. Recently, questions have been raised about whether dumbfounding is a real phenomenon. Two reasons have been proposed as guiding the judgments of dumbfounded participants: harm-based reasons (believing an action may cause harm) or norm-based reasons (breaking a moral norm is inherently wrong). Participants in that research (see Royzman, Kim, & Leeman, 2015), who endorsed either reason were excluded from analysis, and instances of moral dumbfounding seemingly reduced to non-significance. We argue that endorsing a reason is not sufficient evidence that a judgment is grounded in that reason. Stronger evidence should additionally account for (a) articulating a given reason and (b) consistently applying the reason in different situations. Building on this, we develop revised exclusion criteria across three studies. Study 1 included an open-ended response option immediately after the presentation of a moral scenario. Responses were coded for mention of harm-based or norm-based reasons. Participants were excluded from analysis if they both articulated and endorsed a given reason. Using these revised criteria for exclusion, we found evidence for dumbfounding, as measured by the selecting of an admission of not having reasons. Studies 2 and 3 included a further three questions relating to harm-based reasons specifically, assessing the consistency with which people apply harm-based reasons across differing contexts. As predicted, few participants consistently applied, articulated, and endorsed harm-based reasons, and evidence for dumbfounding was found.
