Object-centered attention in 8-month-old infants

We examined the extent to which visual orienting in 8-month-old infants shows evidence of being guided by object-based representations. Infants’ preferences to look at conspicuous targets presented on one of two stationary objects were measured following an event (cue) which directed their covert attention to one of the objects. The results indicate that by 8 months of age a cue presented on one part of an object directs attention to the whole object (object-centered attention). This then affects responses to targets that appear elsewhere on the cued object.     

One nation under God? Yusuf al-Qaradawi’s changing Fiqh of citizenship in the light of the Islamic legal tradition

In the wake of the Arab Revolutions of 2011, countries in the Middle East are grappling with how Islamists might be included within a regime of democratic political pluralism and how their aspirations for an “Islamic state” could affect the citizenship status of non-Muslims. While Islamic jurisprudence on this issue has traditionally classified non-Muslims in Islamic society as protected peoples or dhimma, endowed with what the authors term “minority citizenship”, this article will examine how the transnational intellectual Wasa?iyya or Centrist movement, of which Sheikh Yusuf al-Qaradawi is the figurehead, have sought to develop a new fiqh of citizenship in which Muslims and non-Muslims have equal civil and political rights. This article will focus on Yusuf al-Qaradawi on the basis that his very recent shift in 2010 on the issue is yet to be studied in depth, as well as in view of the fact that the dilemma faced by reformist Islamic scholars—how to integrate modern concepts into a legal tradition while simultaneously arguing for that tradition’s continuing relevance and authority—is for him rendered particularly acute, given that this tradition is itself the very source of his own authority and relevance. It will therefore be argued that the legacy of the Islamic legal tradition structures his discourse in a very specific way, thereby having the potential to render it more persuasive to his audience, and worthy of a more detailed examination.     

Substitution and sameness: two components of a relational conception of the equals sign

A sophisticated and flexible understanding of the equals sign (=) is important for arithmetic competence and for learning further mathematics, particularly algebra. Research has identified two common conceptions held by children: the equals sign as an operator and the equals sign as signaling the same value on both sides of the equation. We argue here that, in addition to these two conceptions, the notion of substitution is also an important part of a sophisticated understanding of mathematical equivalence. We provide evidence from a cross-cultural study in which English and Chinese children were asked to rate the "cleverness" of operational, sameness, and substitutive definitions of the equals sign. A principal components analysis revealed that the substitutive items were distinct from the sameness items. Furthermore, Chinese children rated the substitutive items as 'sort of clever' or 'very clever', whereas English children rated them as not so clever, suggesting that the notion of substitution develops differently across the two countries. Implications for developmental models of children's understanding of equivalence are discussed.     

Luminance affects age-related deficits in object detection: implications for computerized psychological assessments

As psychological instruments are converted for administration on computers, differences in luminance and contrast of these displays may affect performance. Specifically, high-luminance assessments may mask age-group differences that are apparent under lower luminance conditions. We examined the effects of luminance and contrast on object detection using computerized and naturalistic assessments. Younger and older adults displayed more differences in performance across differing contrast levels in conditions that were matched for luminance, despite the conditions appearing perceptually different. These findings indicate that computerized assessments should be created with luminance levels that are similar to those of the tasks they purport to simulate in order to enhance their validity.     

Reasons for Declining Preconception Expanded Carrier Screening Using Genome Sequencing

Genomic carrier screening can identify more disease-associated variants than existing carrier screening methodologies, but its utility from patients’ perspective is not yet established. A randomized controlled trial for preconception genomic carrier screening provided an opportunity to understand patients’ decisions about whether to accept or decline testing. We administered a survey to potential genomic carrier screening recipients who declined participation (N = 240) to evaluate their reasons for doing so. Two thirds of women declined participation. We identified major themes describing reasons these individuals declined to participate; the most common were time limitation, lack of interest, not wanting to know the information, and potential cause of worry or anxiety. Most women eligible for genomic carrier screening indicated that their reasons for opting out were due to logistical issues rather than opposing the rationale for testing. As expanded carrier screening and genomic sequencing become a more routine part of clinical care, it is anticipated there will be variable uptake from individuals for this testing. Thus, the advancement of clinical carrier screening from single genes, to expanded screening panels, to an exome- or genome-wide platform, will require approaches that respect individual choice to receive genetic testing for reproductive risk assessment.     

Pretend play and development in early childhood (with implications for the oedipal phase)

Pretend play reflects both the unique mental organization and the developmental challenges of early to middle childhood, with a trajectory that parallels the monumental transformation of the toddler to the school-age child. Despite evidence for various forms of playing throughout the life cycle, the flowering of symbolic play in this phase is specific, essential, and typically transient in terms of its dominance in the life of the child. It reflects the simultaneous emergence, processing, and integration of the remarkable developmental advances occurring during this period, most especially the capacity to symbolize, in the service of the exponentially expanded psychosexual/social/emotional force field implied in the contemporary use of the term oedipus complex. Moreover, it constitutes a particular mental organization and ego state, with idiosyncratic mentation, affect regulation, and relationship to inner and outer experience, that accompanies the child's gradual orientation to consensual reality. Subsequent access to some form of this state varies widely among individuals but is rarely fully comparable.     

Defective number module or impaired access? Numerical magnitude processing in first graders with mathematical difficulties

This study examined numerical magnitude processing in first graders with severe and mild forms of mathematical difficulties, children with mathematics learning disabilities (MLD) and children with low achievement (LA) in mathematics, respectively. In total, 20 children with MLD, 21 children with LA, and 41 regular achievers completed a numerical magnitude comparison task and an approximate addition task, which were presented in a symbolic and a nonsymbolic (dot arrays) format. Children with MLD and LA were impaired on tasks that involved the access of numerical magnitude information from symbolic representations, with the LA children showing a less severe performance pattern than children with MLD. They showed no deficits in accessing magnitude from underlying nonsymbolic magnitude representations. Our findings indicate that this performance pattern occurs in children from first grade onward and generalizes beyond numerical magnitude comparison tasks. These findings shed light on the types of intervention that may help children who struggle with learning mathematics.     

Meeting a New Me: An Autoethnographic Journey into Kenya and Back

In this article the first author (MG) examines her experiences, reflections, and questions after traveling to Kenya and then attempting to integrate those experiences into her Western life. Using an autoethnographic format, different implications for the author are explored as she becomes more culturally aware both of other ways of being as well as of her own identity. MG publically shared her experiences on three different occasions, and then used a reflective stance to consider the implications of the questions posed for her personally, for the therapy field, and for the meaning of maintaining multicultural competencies.     

Sider,the inheritance of intrinsicality,and theories of composition

I defend coincidentalism (the view that some pluralities have more than one mereological fusion) and restricted composition (the view that some pluralities lack mereological fusions) against recent arguments due to Theodore Sider.
