Visual motherese? Signal‐to‐noise ratios in toddler‐directed television

Younger brains are noisier information processing systems; this means that information for younger individuals has to allow clearer differentiation between those aspects that are required for the processing task in hand (the ‘signal’) and those that are not (the ‘noise’). We compared toddler‐directed and adult‐directed TV programmes (TotTV/ATV). We examined how low‐level visual features (that previous research has suggested influence gaze allocation) relate to semantic information, namely the location of the character speaking in each frame. We show that this relationship differs between TotTV and ATV. First, we conducted Receiver Operator Characteristics analyses and found that feature congestion predicted speaking character location in TotTV but not ATV. Second, we used multiple analytical strategies to show that luminance differentials (flicker) predict face location more strongly in TotTV than ATV. Our results suggest that TotTV designers have intuited techniques for controlling toddler attention using low‐level visual cues. The implications of these findings for structuring childhood learning experiences away from a screen are discussed.     

Instantiation as location

Many familiar forms of property realism identify properties with sui generis ontological categories like universals or tropes and posit a fundamental instantiation relation that unifies objects with their properties. In this paper, I develop and defend locationism, which identifies properties with locations and holds that the occupation relation that unifies objects with their locations also unifies objects with their properties. Along with the theoretical parsimony that locationism enjoys, I argue that locationism resolves a puzzle for actualists regarding the ontological status of uninstantiated properties. I also note some promising applications of the locationist framework to the metaphysics of quantities and possible worlds.     

Is burnout solely job‐related? A critical comment

Within the field‐dominating, multidimensional theory of burnout, burnout is viewed as a work‐specific condition. As a consequence, the burnout syndrome cannot be investigated outside of the occupational domain. In the present paper, this restrictive view of burnout's scope is criticized and a rationale to decide between a work‐specific and a generic approach to burnout is presented. First, the idea that a multidimensional conception of burnout implies a work‐restricted scope is deconstructed. Second, it is shown that the burnout phenomenon cannot be confined to work because chronic, unresolvable stress – the putative cause of burnout – is not limited to work. In support of an integrative view of health, it is concluded that the field‐dominating, multidimensional theory of burnout should abandon as groundless the idea that burnout is a specifically job‐related phenomenon and define burnout as a multi‐domain syndrome. The shift from a work‐specific to a generic approach would allow both finer analysis and wider synthesis in research on chronic stress and burnout.     

Causation in a timeless world

This paper offers a new way to evaluate counterfactual conditionals on the supposition that actually, there is no time. We then parlay this method of evaluation into a way of evaluating causal claims. Our primary aim is to preserve, at a minimum, the assertibility of certain counterfactual and causal claims once time has been excised from reality. This is an important first step in a more general reconstruction project that has two important components. First, recovering our ordinary language claims involving notions such as persistence, change and agency and, second, recovering enough observational evidence so that any timeless metaphysics is not empirically self-refuting. However, the project of investigating causation in a timeless setting has a greater relevance than its application to timeless physical theory alone. For, as we show, it can be used to model the assertibility conditions of causal claims more generally.     

Late Abrahamic reunion? Religious fundamentalism negatively predicts dual Abrahamic group categorization among Muslims and Christians

Although extensive research has documented the effectiveness of common or dual in‐groups on improving intergroup relations, little is known about how individual‐difference variables affect people's willingness to make such re‐categorizations in the first place. Here, we demonstrate that individual differences in religious fundamentalism predict willingness to categorize in terms of the common Abrahamic religious origins of Christianity and Islam among Christians and Muslims. Study 1 (n = 243 Christians, 291 Muslims) uses multigroup structural equation modeling and Study 2 (n = 80 Christians) an experimental manipulation to show that religious fundamentalism causes lower dual Abrahamic categorization, which, in turn, predicts more positive attitudes toward the respective out‐group, mediating the negative effects of religious fundamentalism on religious intergroup bias. While making the general case that individual differences may play important roles for dual categorizations, these results also highlight the specific positive potential of dual ecumenical categorizations for improving interreligious relations. Research and societal implications are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

The Role of Working Memory and Divided Attention in Metaphor Interpretation

Although several types of figurative language exist, neuropsychological tests of non-literal language have focused on proverbs. Metaphors in the form X is (a) Y (e.g., The body’s immunological response is a battle against disease.) place a lower demand on language skills and are more easily manipulated for novelty than proverbs. Forty healthy participants completed the Metaphor Interpretation Test (developed by the authors). The task includes 20 items chosen from a list of metaphors that were rated on several scales (e.g. imagery, aptness) in a study by Katz et al. (Metaphor Symb Act 3(4):191–214, 1988). Participants were asked to rate the familiarity and provide an explanation of each metaphor. A scoring system was developed to categorize answers into: abstract complete (AC), abstract partial (AP), concrete (CT), and other/unrelated (OT) types. Participants also completed short-term memory and divided attention tests. Overall, participants produced 56 % AC, 25.38 % AP, 7.88 % CT, and 10.88 % OT responses. It was found that a measure of verbal short-term memory span was the best predictor of performance on this task (adjusted \(R^{2}= .369\) ). It appears that short-term memory span, not working memory or divided attention, contributes most to providing abstract responses in explaining metaphors. This is in line with the idea that when one accesses the semantic network associated with a novel metaphor, one must hold this information in mind long enough to search for and link similar cognitive networks.     

A Systemic Analysis of Cheating in an Undergraduate Engineering Mechanics Course

Cheating in the undergraduate classroom is not a new problem, and it is recognized as one that is endemic to the education system. This paper examines the highly normative behavior of using unauthorized assistance (e.g., a solutions manual or a friend) on an individual assignment within the context of an upper division undergraduate course in engineering mechanics. The findings indicate that there are varying levels of accepting responsibility among the students (from denial to tempered to full) and that acceptance of responsibility can lead to identification of learning and necessary behavioral changes. The findings have implications for institutions and engineering faculty, in particular the need for consistent academic integrity education and the teaching of professional integrity and ethics.
