Many researchers, including Clarke and Beck, describe the human numerical system as unitary. We offer an alternative view – the coexistence of several systems; namely, multiple systems existing in parallel, ready to be activated depending on the task/need. Based on this alternative view, we present an account for the representation of rational numbers.

Number-form synesthetes consciously experience numbers in spatially-defined locations. For non-synesthete individuals, a similar association of numbers and space appears in the form of an implicit mental number line as signified by the distance effect–reaction time decreases as the numerical distance between compared numbers increases. In the current experiment, three number-form synesthetes and two different non-synesthete control groups performed a number comparison task. Synesthete participants exhibited a sizeable distance effect only when presented numbers were congruent with their number-form. In contrast, the (...) controls exhibited a distance effect regardless of congruency or presentation type. The findings suggest that: number-form synesthesia impairs the ability to represent numbers in a flexible manner according to task demands; number-form synesthesia is a genuine tangible experience, triggered involuntarily; and the classic mental number line can be more pliable than previously thought and appears to be independent of cultural-lingo direction.

We agree with Cramer et al. that pure cases of behavioral disorders with no symptom overlaps are rare. However, we argue that disorders do exist and the network idea is limited and limiting. Networks of symptoms are observed mainly at behavioral levels. The core deficit is commonly at the cognitive or brain levels, and there the story is completely different.

Simple specialization cannot account for brain functioning. Yet, we believe Anderson's reuse can be better explained by re-function. We suggest that functional demands shape brain changes and are the driving force behind reuse. For example, we suggest that the prefrontal cortex (PFC) is built as an infrastructure for multi-functions rather than as a module for reuse.

It is widely agreed that irrelevant numerical values are automatically activated. However, automatic and intentional activations may give rise to different numerical representations. We examined processing of symbolic and non-symbolic representations asking whether they differ in automatic and intentional processing. Participants were presented with two-dimensional displays containing repetitions of a digit and were asked to report, in different blocks, whether the digit or numerosity was smaller or larger than 5. Incongruent trials differed either in laterality between the relevant and irrelevant (...) dimensions or in numerical distance between dimensions. Congruency affected performance regardless of symbolic or non-symbolic presentation. For incongruent trials, laterality affected performance, again regardless of presentation. This implies that automaticity does not mean similar processing of relevant and irrelevant dimensions. Specifically, the relevant dimension is processed elaborately whereas the irrelevant dimension is processed crudely. (shrink)

Number is known for influencing time processing, but to what extent time influences number in human adults is unclear. We investigated possible bidirectional interactions using a novel Stroop-like task; participants compared numbers or temporal durations in congruent or incongruent conditions . Time and number tasks were presented in different blocks or within the same block of trials with task instructions provided at the offset of the stimuli . Analyses of response times and their distribution revealed that number affected time from (...) early RTs, and time affected number at late RTs – an asymmetry observed only when time and number tasks were presented in separate blocks. Thus, carefully chosen tasks and appropriate data analysis can reveal bidirectionality between time and number, consistent with shared magnitude or decision mechanisms. (shrink)

Numbers are fundamental to our understanding of, and survival in, the environment. Not surprisingly, numbers represent an important psychological dimension in triggering synaesthetic experiences, such as in digit-colour synaesthesia, or number-space synaesthesia. Another important consideration is directionality in synaesthesia, in that we might ask whether the stimulus and response in any given synaesthetic variant can also work on the opposite way. Most studies have documented the typical direction of the synaesthetic experience from the inducer to the concurrent. However, it seems (...) that some synaesthetes do show bi-directionality, that is, their concurrent might also trigger the inducer either at an implicit level, or even at the explicit level that reaches perceptual awareness. We discuss these two issues in this book chapter. We will first explore synesthesia and automaticity where numbers are concerned, followed by a discussion on synaesthesia and directionality.

Conceptualizing intelligence in its biological context, as the expression of manifold adaptations, compels a rethinking of measuring this characteristic in humans, relying also on animal studies of analogous skills. Mental manipulation, as an extension of object manipulation, provides a continuous, biologically based concept for studying G as it pertains to individual differences in humans and other species.

Are small and large numbers represented similarly or differently on the mental number line? The size effect was used to argue that numbers are represented differently. However, recently it has been argued that the size effect is due to the comparison task and is not derived from the mental number line per se. Namely, it is due to the way that the mental number line is mapped onto the task-relevant output component. Here synesthesia was used to disentangle these two alternatives. (...) In two naming experiments a digit-color synesthete showed that the congruity effect was modulated by number size. These results support the existence of a mental number line with a vaguer numerical representation as numbers increase in size. In addition, the results show that in digit-color synesthesia, colors can evoke numerical representation automatically. (shrink)

In this commentary we make two rejoinders to Jung & Haier (J&H). First, we highlight the response selection component in tasks as a confounding variable that may explain the parieto-frontal involvement in studies of human intelligence. Second, we suggest that efficient response selection may be an integral part of the definition of intelligence.

Representations of the fingers are embodied in our cognition and influence performance in enumeration tasks. Among deaf signers, the fingers also serve as a tool for communication in sign language. Previous studies in normal hearing (NH) participants showed effects of embodiment (i.e., embodied numerosity) on tactile enumeration using the fingers of one hand. In this research, we examined the influence of extensive visuo‐manual use on tactile enumeration among the deaf. We carried out four enumeration task experiments, using 1–5 stimuli, on (...) a profoundly deaf group (n = 16) and a matching NH group (n = 15): (a) tactile enumeration using one hand, (b) tactile enumeration using two hands, (c) visual enumeration of finger signs, and (d) visual enumeration of dots. In the tactile tasks, we found salient embodied effects in the deaf group compared to the NH group. In the visual enumeration of finger signs task, we controlled the meanings of the stimuli presentation type (e.g., finger‐counting habit, fingerspelled letters, both or neither). Interestingly, when comparing fingerspelled letters to neutrals (i.e., not letters or numerical finger‐counting signs), an inhibition pattern was observed among the deaf. The findings uncover the influence of rich visuo‐manual experiences and language on embodied representations. In addition, we propose that these influences can partially account for the lag in mathematical competencies in the deaf compared to NH peers. Lastly, we further discuss how our findings support a contemporary model for mental numerical representations and finger‐counting habits. (shrink)

Existing whistle-blowing models rely on “cold” economic calculations and cost-benefit analyses to explain the judgments and actions of potential whistle-blowers. I argue that “hot” cognitions – value conflict and emotions – should be added to these models. I propose a model of the whistle-blowing decision process that highlights the reciprocal influence of “hot” and “cold” cognitions and advocate research that explores how value conflict and emotions inform reporting decisions. I draw on the cognitive appraisal approach to emotions and on the (...) social-functional value pluralism model to generate propositions. (shrink)

Demonstrating the connections between contemporary psychoanalysis, Jewish thought and Jewish history, this volume is a significant contribution to the traditions of dialogue, debate and change-within-continuity that epitomize these disciplines. The authors of this volume explore the cross-disciplinary connections between psychoanalysis and Jewish thought, while seeking out the resonance of new meanings, to exemplify the uncanny similarities that exist between ancient Rabbinic methods of interpretation and contemporary psychoanalytic theory and methodology, particularly the centrality of the question and the deconstruction of narrative. (...) In doing so, this collaboration addresses the bi-directional influence between, and the relevance of, the Jewish interpretive tradition and psychoanalysis to provide readers with renewed insight into key topics such as Biblical text and midrash, religious traditions, trauma, gender, history, clinical work and the legacies of the Holocaust on psychoanalytic theory. Creating an intimate environment for interdisciplinary dialogue, this is an essential book for students, scholars and clinicians alike, who seek to understand the continued significance of the multiple connections between psychoanalysis and Jewish thought.

Sociological studies of women's experiences with conservative religions are typically framed by a paradox that ponders women's complicity. The prevailing view associates agency with strategic subjects who use religion to further extra-religious ends and pays little attention to the cultural and institutional contexts that shape “compliance.” This paper suggests an alternative framing. Rather than asking why women comply, I examine agency as religious conduct and religiosity as a constructed status. Drawing on a study that examined how orthodox Jewish Israeli women (...) observe, negotiate, and make sense of regulations of marital sexuality, this paper explains religious women's agency as religious conduct, or the “doing” of religion. I demonstrate that doing religion is associated with a search for authentic religious subjecthood and that religiosity is shaped in accordance with the logics of one's religion, and in the context of controlling messages about threatened symbolic boundaries and cultural Others.

Causal independence of the simultaneous positions and momenta of two distinguishable particles in nonrelativistic physics and causal independence of events in two relatively spacelike regions of space-time in relativity are analyzed and discussed. This review paper formulates causal independence in a general and operational way and summarizes the inferences drawn from it in non-relativistic quantum mechanics, classical relativistic point mechanics, quantum field theory, and classical field theory. Special attention is given to the open question of the relationship between local independence (...) and commutativity in quantum field theory. (shrink)

This special issue is the result of concerns about the marginalized status of gender within the sociology of religion. The collection of exciting new research in this special issue advocates for the importance of a gender lens on questions of religion in order to highlight issues, practices, peoples, and theories that would otherwise not be central to the discipline. We encourage sociologists who study religion to engage more in interdisciplinary and intersectional scholarship, acknowledge developments in the global South, and develop (...) more compelling theoretical frameworks that analyze religion from a gendered perspective. Our aim is to bring religion to the attention of gender and feminist scholars and to encourage religion scholars to consider gender not just as a variable but as a social structure. We hope that both groups of scholars will consider gender and religion as mutually constitutive social categories. (shrink)

ABSTRACT This paper is concerned with the question of whether an individual has a moral obligation to sign a protest petition which has been initiated on moral grounds. It is argued that there is such an obligation when the petition represents a viewpoint with which one broadly agrees. This is a general dury which may lapse with changed circumstances or which may be redeemed by some alternative action. It is argued that the duty to initiate a protest petition is, on (...) the other hand, supererogatory as far as an individual is concerned, but may be a duty for a community or group. Finally it is argued that protest petitions are essentially protests, not against evil deeds as such, but against evil deeds done in one's own name, and are therefore a vital aspect of democracy.
