Deontic and epistemic reasoning in children revisited: Comment on Dack and Astington

Dack and Astington (Journal of Experimental Child Psychology 110 2011 94–114) attempted to replicate the deontic reasoning advantage among preschoolers reported by Cummins (Memory & Cognition 24 1996 823–829) and by Harris and Nuñez (Child Development. 67 1996 572–1591). Dack and Astington argued that the apparent deontic advantage reported by these studies was in fact an artifact due to a methodological confound, namely, inclusion of an authority in the deontic condition only. Removing this confound attenuated the effect in young children but had no effect on the reasoning of 7-year-olds and adults. Thus, removing reference to authority “explains away” young children’s apparent precocity at this type of reasoning. But this explanation rests on (a) a misunderstanding of norms as targets of deontic reasoning and (b) conclusions based on a sample size that was too small to detect the effect in young children.     

Specifying the human body configuration

Three experiments investigated the specific spatial relations that define the human body configuration. In Experiment 1, participants searched for scrambled bodies amongst normal distractors. In Experiments 2 and 3 participants were asked to identify whether single body images (upright or inverted) were scrambled or normal. Scrambled bodies had head or limbs displaced to either symmetrical or asymmetrical positions. Experiment 1 showed that asymmetrical violations are recognized faster than symmetrical violations. All three experiments revealed that when the number of structural violations is held constant, head violations are recognized faster than limb violations. Experiment 3 also showed a greater inversion effect for scrambled bodies that maintained head on top and vertical symmetry, providing evidence that these are key spatial relations in the human body configuration. Overall, the results supported our hypothesis that the human body configuration is defined primarily by a head at the apex of a vertically symmetrical body.     

Comparison Theory in Economic Psychology Regarding the Easterlin Paradox and Decreasing Marginal Utility: a Critique

This paper challenges the assumption within Economics that the relationship between money and subjective wellbeing is determined by processes of cognitive comparison. An alternative explanation for such well known phenomena as the Easterlin Paradox and Decreasing Marginal Utility are provided through a consideration of affect. The theoretical basis for such explanations relies on theory from Psychology usually overlooked by Economists, such as affect heuristics and Subjective Wellbeing Homeostasis. The presented evidence for this alternative source of explanation melds psychological theory with empirical data. It is concluded that affective processes offer a coherent alternative explanation for the phenomena under discussion.

Validation of the Personal Wellbeing Index for People with End Stage Kidney Disease

The quality of life of people with end stage kidney disease (ESKD) has traditionally been measured using instruments that emphasise objective health status. The present study validates an alternative measure, the Personal Wellbeing Index (PWI), which measures subjective wellbeing. An Australian ESKD sample (N?=?172, Mean age?=?64.04, SD?=?14.82) completed the PWI as well as health-specific quality of life measures. The PWI was subject to confirmatory factor analysis, and a series of regressions and between-group comparisons were performed to reveal that it is a psychometrically appropriate measure for this sample. The PWI and health-specific measures each yield different and complementary results. Thus, the PWI is proposed as a complement to existing health-related quality of life tools, in order to broaden understanding of the patient’s subjective experience. The resulting profile is argued to better inform targeted interventions to improve the quality of life of people with ESKD.     

How the Social Environment Shaped the Evolution of Mind

Dominance hierarchies are ubiquitous in the societies of human and non-human animals. Evidence from comparative, developmental, and cognitive psychological investigations is presented that show how social dominance hierarchies shaped the evolution of the human mind, and hence, human social institutions. It is argued that the pressures that arise from living in hierarchical social groups laid a foundation of fundamental concepts and cognitive strategies that are crucial to surviving in social dominance hierarchies. These include recognizing and reasoning transitively about dominance relations, fast-track learning of social norms (permissions, prohibitions, and obligations), detecting violations of social norms (cheating), monitoring reciprocal obligations, and reading the intentions of others.     

Why it doesn’t matter to metaphysics what Mary learns

The Knowledge Argument of Frank Jackson has not persuaded physicalists, but their replies have not dispelled the intuition that someone raised in a black and white environment gains genuinely new knowledge when she sees colors for the first time. In what follows, we propose an explanation of this particular kind of knowledge gain that displays it as genuinely new, but orthogonal to both physicalism and phenomenology. We argue that Mary’s case is an instance of a common phenomenon in which something new is learned as the result of exploiting representational resources that were not previously exploited, and that this results in gaining genuinely new information.     

AN EXAMINATION OF WOMEN'S PERSPECTIVES ON POWER

Historically, theoretical and popular conceptions about power have not included or addressed women's experiences. This study adds to the growing body of knowledge about women by examining women's perceptions of and relationship to power. One hundred twenty-five women, ranging in age from 21 to 63, were asked to define and explore power through a variety of structured and open-ended questions. The results showed that women's definition of power differed significantly from their perception of society's definition of power, as well as from the way power has traditionally been conceptualized. More theoretical and empirical attention should be given to understanding the role of personal authority in both women's and men's experience of power.     

Are children with Specific Language Impairment competent with the pragmatics and logic of quantification?

Specific Language Impairment (SLI) is understood to be a disorder that predominantly affects phonology, morphosyntax and/or lexical semantics. There is little conclusive evidence on whether children with SLI are challenged with regard to Gricean pragmatic maxims and on whether children with SLI are competent with the logical meaning of quantifying expressions. We use the comprehension of statements quantified with ‘all’, ‘none’, ‘some’, ‘some…not’, ‘most’ and ‘not all’ as a paradigm to study whether Spanish-speaking children with SLI are competent with the pragmatic maxim of informativeness, as well as with the logical meaning of these expressions.Children with SLI performed more poorly than a group of age-matched typically-developing peers, and both groups performed more poorly with pragmatics than with logical meaning. Moreover, children with SLI were disproportionately challenged by pragmatic meaning compared to their age-matched peers. However, the performance of children with SLI was comparable to that of a group of younger language-matched typically-developing children. The findings document that children with SLI do face difficulties with employing the maxim of informativeness, as well as with understanding the logical meaning of quantifiers, but also that these difficulties are in keeping with their overall language difficulties rather than exceeding them. The implications of these findings for SLI, linguistic theory, and clinical practice are discussed.     

Embodied task dynamics

Movement science faces the challenge of reconciling parallel sequences of discrete behavioral goals with observed fluid, context-sensitive motion. This challenge arises with a vengeance in the speech domain, in which gestural primitives play the role of discrete goals. The task dynamic framework has proved effective in modeling the manner in which the gestural primitives of articulatory phonology can result in smooth, biologically plausible, movement of model articulators. We present a variant of the task dynamic model with 1 significant innovation: Tasks are not abstract and context free but are embodied and tied to specific effectors. An advantage of this approach is that it allows the definition of a parametric cost function that can be optimized. Optimization generates gestural scores in which the relative timing of gestures is fully specified. We demonstrate that movements generated in an optimal manner are phonetically plausible. Highly nuanced movement trajectories are emergent based on relatively simple optimality criteria. This addresses a long-standing need within this theoretical framework and provides a rich modeling foundation for subsequent work.
