Basic numerical capacities and prevalence of developmental dyscalculia: the Havana Survey

The association of enumeration and number comparison capacities with arithmetical competence was examined in a large sample of children from 2nd to 9th grades. It was found that efficiency on numerical capacities predicted separately more than 25% of the variance in the individual differences on a timed arithmetical test, and this occurred for both younger and older learners. These capacities were also significant predictors of individual variations in an untimed curriculum-based math achievement test and on the teacher scores of math performance over developmental time. Based on these findings, these numerical capacities were used for estimating the prevalence and gender ratio of basic numerical deficits and developmental dyscalculia (DD) over the grade range defined above (N = 11,652 children). The extent to which DD affects the population with poor ability on calculation was also examined. For this purpose, the prevalence and gender ratio of arithmetical dysfluency (AD) were estimated in the same cohort. The estimated prevalence of DD was 3.4%, and the male:female ratio was 4:1. However, the prevalence of AD was almost 3 times as high (9.35%), and no gender differences were found (male:female ratio = 1.07:1). Basic numerical deficits affect 4.54% of school-age population and affect more boys than girls (2.4:1). The differences between the corresponding estimates were highly significant (α < .01). Based on these contrastive findings, it is concluded that DD, defined as a defective sense of numerosity, could be a distinctive disorder that affects only a portion of children with AD.     

Employability capacities and organisational commitment foci of human resource professionals: An exploratory study

This study explored the relationship between employees’ employability capacities and their organisational commitment foci. A convenience sample of 196 South African human resource professionals participated in the study, consisting of 73% females and 88% black African people, predominantly within their early career stages (aged > 45 years). Data on individuals’ employability capacities and organisational commitment were collected via questionnaires. Canonical correlation analysis (CCA) was performed to assess the association between the variables of employability capacities and organisational commitment foci. Participants’ lifelong learning capacities (goal-directed behaviour and continuous learning orientation) were positively associated with their career commitment. This finding suggests that a strong lifelong orientation is likely to increase involvement in one’s occupation within the organisation, which contributes to organisational commitment. Lifelong learning capacities appear important to human resource professionals’ career development within their employer organisation.     

Inhibiting the mentalizing capacities

This paper describes a phobic patient who inhibited her capacity to mentalize defensively in situations when emotionally overwhelmed. When provoked by anxiety, she used the ‘silencing-method’, not reflecting on her internal world or her relationships. In order to avoid painful thinking, she stopped mentalizing and used practical or physical activities as a psychic retreat from an unpleasant reality. In psychoanalysis, she developed a growing tolerance to conceiving her own mental states However, even after several years of analysis, inhibiting her mentalizing capacities remained her defensive strategy. This paper suggests that phobia could be understood as an intolerance of conceiving mental states, preventing integration of psychic trauma. Improvement of the mentalizing capacities through psychoanalysis makes phobic symptoms fade.     

The goodness of fragility: on the prospect of genetic technologies aimed at the enhancement of human capacities

Beginning with the assumptions that genetic technology will make possible the enhancement of some significant human capacities and that our society will have self-evident reasons to pursue such enhancements, this essay suggests less evident reasons to proceed with extreme caution. The essay asks: Will we, in our attempts to enhance humans by reducing their subjection to chance and change, inadvertently impoverish them? It explores how technologies aimed at enhancement might affect the good that is our experience of some forms of the beautiful and the excellent, the good that is relationships of care, and the good that is diversity across the life span. In the end, it speculates about the fundamental philosophical difference that underlies the disagreement between those who would tend to embrace a project to enhance human capacities and those who would tend to criticize such a project.     

Learning argumentative capacities

In the fields of linguistics and psychology the didactic implementation of new knowledge relative to argumentative discourse and its acquisition has led us to develop a didactic sequence focused on the teaching of argumentation in 11–12 year old pupils. This sequence was experimented in six schools in order to assess the effect of these new educational methods on the capacities of pupils to treat the dialogic dimensions of argumentation in the writing of monologues. An analysis of the productions of the puils who had been submitted to the didactic sequence, compared with those of a control group, showed a significant improvement in the capacities of the first group. These improvements concerned aspects such as backing up arguments, acknowledging the addressee, negotiating with an eventual contradictor and using of a certain number of units and linguistic expressions t specific to argumentative texts (expressions of responsability taking, textual organisers of cause and conclusion, modalisations of probability and of certitude, concessions and polite expressions).     

Inhibition and shifting capacities mediate adults' age-related differences in strategy selection and repertoire

Young and older adults differ in how many strategies they use to accomplish cognitive tasks. They also differ in how often they select the best strategy on each problem. Two experiments were run to determine whether two executive functions—inhibition and shifting capacities—mediate age-related differences in strategy repertoire and in strategy selection. Both experiments were run in arithmetic problem solving. In Experiment 1, young and older adults’ strategy repertoire was assessed on a problem-by-problem basis while participants solved two-digit addition problems (e.g., 42 + 76). In Experiment 2, young and older participants had to select the best strategy on each problem to find estimates of two-digit multiplication problems (e.g., 43 × 72). In both experiments, individuals’ inhibition and shifting capacities were assessed with the Trail Making Test and the Stroop Test. The main results showed that (a) older adults used a smaller strategy repertoire (Expt. 1) and selected the best strategy on each problem less frequently (Expt. 2) than young adults, (b) inhibition and shifting capacities mediated age-related differences in strategy repertoire and strategy selection, and unique age effects were no longer significant in strategy repertoire but were still significant in strategy selection after statistical control of inhibition and shifting capacities. We discuss important implications of these findings to further our understanding of strategic variations during cognitive aging.     

Implications of an Emerging Integration of Universal and Culturally Specific Psychologies

ABSTRACT— Psychological researchers increasingly recognize that human behavior reflects a complex interplay of universal human capacities, cultural responses to unique histories and circumstances, and individual differences. Many psychological processes appear to reflect culturally specific instantiations of universal capacities. Current integrative research focuses on further clarifying definitions of universality and on refining methods for identifying universal and cultural components of psychological processes. In this article, we consider implications of this emerging integration. To illustrate possible implications for psychology, we apply it to the study of psychopathology. We report on formal models that explain why some cultures embrace dysfunction among members. We then use the integrative framework to describe methods for determining whether putative disorders bring universal or contextual life dysfunction and to clarify etiological models of three disorders. Models of psychopathology can be more informed and precise if they include careful consideration of both universal and cultural influences on behavior.     

Some capacities required to be a psychoanalytic psychotherapist

The capacities required to be a helpful psychoanalytic psychotherapist include those required for any meaningful interpersonal relationship that involves the deepest thoughts and feelings between two people, where one is committed to always putting first the best interests of the other. This paper discusses seven of those capacities: (1) the capacity for empathie technical flexibility; (2) the capacity to be childlike; (3)the capacity for psychological mindedness and insight; (4) the capacity to be neutral but not anonymous; (5) the capacity to recognize, articulate, bear and experience feelings within the session; (6) the capacity to be silent; and (7) the capacity to regress in the service of therapy. Each of these capacities is discussed within the context of practical aspects of delivering psychotherapy.     

Sex differences in the adolescent brain

Adolescence is a time of increased divergence between males and females in physical characteristics, behavior, and risk for psychopathology. Here we will review data regarding sex differences in brain structure and function during this period of the lifespan. The most consistent sex difference in brain morphometry is the 9–12% larger brain size that has been reported in males. Individual brain regions that have most consistently been reported as different in males and females include the basal ganglia, hippocampus, and amygdala. Diffusion tensor imaging and magnetization transfer imaging studies have also shown sex differences in white matter development during adolescence. Functional imaging studies have shown different patterns of activation without differences in performance, suggesting male and female brains may use slightly different strategies for achieving similar cognitive abilities. Longitudinal studies have shown sex differences in the trajectory of brain development, with females reaching peak values of brain volumes earlier than males. Although compelling, these sex differences are present as group averages and should not be taken as indicative of relative capacities of males or females.     

The demands and capacities model: Response to siegel

Responses to the recent critical comments of Gerald Siegel to the demands and capacities model are given. A brief history of the model's development is followed by direct explanations of its empirical support and logical development. It appears that Dr. Siegel may have referred only to one of our publications on the model. His concern about difficulties in measuring capacities is also addressed. Finally, the logic of the model is explicated and a misunderstanding regarding the use of direct therapy is clarified.     

Evaluation of the attentional capacities and working memory of early and late blind persons

Although attentional processes and working memory seem to be significantly involved in the daily activities (particularly during navigating) of persons who are blind and who use these abilities to compensate for their lack of vision, few studies have investigated these mechanisms in this population. The aim of this study is to evaluate the selective, sustained and divided attention, attentional inhibition and switching and working memory of blind persons. Early blind, late blind and sighted participants completed neuropsychological tests that were designed or adapted to be achievable in the absence of vision. The results revealed that the early blind participants outperformed the sighted ones in selective, sustained and divided attention and working memory tests, and the late blind participants outperformed the sighted participants in selective, sustained and divided attention. However, no differences were found between the blind groups and the sighted group in the attentional inhibition and switching tests. Furthermore, no differences were found between the early and late blind participants in this set of tests. These results suggest that early and late blind persons can compensate for the lack of vision by an enhancement of the attentional and working memory capacities.     

Individual differences in learning to perceive length by dynamic touch: Evidence for variation in perceptual learning capacities

Recent studies of perceptual learning have explored and commented on variation in learning trajectories. Although several factors have been suggested to account for this variation, thus far the idea that humans vary in their perceptual learning capacities has received scant attention. In the present experiment, we aimed at providing a detailed picture of the variation in this capacity by investigating the perceptual learning trajectories of a considerable number of participants. The learning process was studied using the paradigm of length perception by dynamic touch. The results showed that there are substantial individual differences in the way perceivers respond to feedback. Indeed, after feedback, the participants' perceptual performances diverged. We conclude that humans vary in their perceptual learning capacities. The implications of this finding for recent discussions on variation in perception are explored.     

Beyond the Isolated Self: Extended Mind and Spirituality

Extended Cognition is a theory from philosophy of mind that has its roots in the more general notion of Embodied Cognition. Embodied cognition understands all human thought as involving the body (not just the brain), and as always situated in particular contexts. Cognitive extension goes further to suggest that intelligent mental processes often include things outside the brain and body, involving interactions with other persons or external artifacts that significantly enhance cognitive capacities. Thus, while intelligence was once thought to be an attribute of a single individual’s brain, it is now understood to extend into processes outside the person within immediate interactive space. For example, smart phones or problem-solving groups expand cognitive capacities beyond what is possible on one’s own. This article explores the possibility of supersizing-through-extension spirituality and Christian life within the interactive space of congregations and religious communities.     

Lateralization of speech processing in the brain as indicated by mismatch negativity and dichotic listening

The goal of the present study was to evaluate the differences between dichotic listening and mismatch negativity as measures of speech lateralization in the human brain. For this purpose, we recorded the magnetic equivalent of the mismatch negativity, elicited by consonant-vowel syllable change, and tested the same subjects in the dichotic listening procedure. The results showed that both methods indicated left-hemisphere dominance in speech processing. However, the mismatch negativity, as compared to the right-ear advantage, suggested slightly stronger left-hemisphere dominance in speech processing. No clear correlation was found between the laterality indexes of mismatch negativity and right-ear advantage calculated from dichotic listening results. The possible explanation for this finding would be that these two measures reflect different stages of speech processing in the human brain.     

The role of performance in the demands and capacities model

The Demands and Capacities Model (DCM) has become an influential framework for considering the factors that are believed to influence the development of stuttering in young children, even though several key aspects of the model have not been fully developed. Siegel (this issue, page 323) raised several valid concerns that must be addressed if the DCM is to achieve its potential for explaining childhood stuttering and suggested that the model would be improved if the elusive concept of capacities were replaced by the more concrete and measurable concept of performance. This paper proposes modifications to the DCM that may help to address several of Siegel's concerns and evaluates the role of performance in understanding the development of childhood stuttering. It is suggested that replacing capacity with performance does not solve the problems identified by Siegel, because implicit assumptions about the child's underlying abilities are still required if the model is to explain a breakdown in speaking performance. To address Siegel's concerns more directly, a different solution is proposed based on reframing the conceptual notions of demands and capacities in terms of measurable aspects of a child's speaking performance and speaking abilities.     

A system for behavioral evaluation of the visual capacities of cats

An automated testing apparatus for evaluating the visual capacities of cats is described. It features ease of training, reliability, and flexibility in the type of stimuli that can be presented. For presentation of complex visual stimuli, a closed circuit television display system has been devised that is compatible with the behavioral testing apparatus.     

An fMRI investigation of analogical mapping in metaphor comprehension: the influence of context and individual cognitive capacities on processing demands

This study used fMRI to investigate the neural correlates of analogical mapping during metaphor comprehension, with a focus on dynamic configuration of neural networks with changing processing demands and individual abilities. Participants with varying vocabulary sizes and working memory capacities read 3-sentence passages ending in nominal critical utterances of the form "X is a Y." Processing demands were manipulated by varying preceding contexts. Three figurative conditions manipulated difficulty by varying the extent to which preceding contexts mentioned relevant semantic features for relating the vehicle and topic of the critical utterance to one another. In the easy condition, supporting information was mentioned. In the neutral condition, no relevant information was mentioned. In the most difficult condition, opposite features were mentioned, resulting in an ironic interpretation of the critical utterance. A fourth, literal condition included context that supported a literal interpretation of the critical utterance. Activation in lateral and medial frontal regions increased with increasing contextual difficulty. Lower vocabulary readers also had greater activation across conditions in the right inferior frontal gyrus. In addition, volumetric analyses showed increased right temporo-parietal junction and superior medial frontal activation for all figurative conditions over the literal condition. The results from this experiment imply that the cortical regions are dynamically recruited in language comprehension as a function of the processing demands of a task. Individual differences in cognitive capacities were also associated with differences in recruitment and modulation of working memory and executive function regions, highlighting the overlapping computations in metaphor comprehension and general thinking and reasoning.     

From archaic narcissism to empathy for the self: the evolution of new capacities in psychoanalysis

The concept of the selfobject was central to Heinz Kohut's psychology of the self. With an eye to studying the development of narcissism and its implications for the growth of new psychic structure, this concept is reviewed and reassessed. Post-Kohutian complexities regarding its definition and use extend our consideration of the development of narcissism beyond archaic configurations toward further evolution of the self and the nature of mature narcissism. The hypothesis is offered that developing narcissism and the growth of self-regulation impact the acquisition of new structure and new capacities through the emergence of newly potentiated aspects of the self. The implications of these emergent qualities of the self are examined in the context of our understanding of self-esteem regulation, the state of the self, and the goals of psychoanalysis. A clinical example illustrates how technique and process in an analysis may be organized around the development of such new capacities.     

The Human Meaning of the Brain

This study attempts to show that brain research brings to light religious meanings. There is a physical basis of religion in that the way the brain has evolved makes possible the religious meanings of human experience. The brain grows out of and reflects the universe. The brain is an icon of God. In the analysis of the brain's various parts and functions the relational dimensions of reality are uncovered in their physical basis. This points to ultimate reality as social and to a social God. As such, the structures of reality, experienced through the brain, reflect the reality of God.     

Emotional self-regulation in preschoolers: The interplay of child approach reactivity, parenting, and control capacities

This study examined whether child temperamental approach reactivity moderated the association between 2 factors, parenting and child control capacities and child emotional self-regulation. Participants (N = 113) were 3- and 4-year-olds (M = 48 months, SD = 5.78) and their mothers. Emotional self-regulation was measured as observed persistence and frustration and as maternal report of compliance. Parental approach, avoidance, control, and warmth were observed during play and a frustrating wait. Child approach reactivity and control capacities (inhibitory control and soothability) were assessed via maternal report. Results suggested that maternal approach during the wait was associated with persistence and frustration, whereas maternal warmth during the play was associated with compliance. These effects, and those of child control capacities, depended on the level of child approach. The implications of reactivity-control interactions and parent-child goodness-of-fit for emotional self-regulation are discussed.
