The paradox between the numerically competent baby and the slow learning of two- to four-year-old children / La paradoja entre el bebé numéricamente competente y el lento aprendizaje de los niños de dos a cuatro años de edad

Abstract

Since the 1980s, numerous laboratory investigations have been arguing that infants are numerically competent. This work presents a critical review of this line of research. We propose that despite the repertoire of numerical abilities attributed to infants and the seemingly natural character of the very first numbers in the numerical series, the semiotic complexity of their use and comprehension poses a cognitive challenge that children undertake, motivated, supported and often guided by others. This challenge involves a high degree of semiotic organization of the material world as well as an ability to manage early sign systems, systems which children learn how to use during their first years of life and which form the platform on which numbers are based.     

Metapsychology or metapsychologies? Some comments on Paul Denis's paper ‘The drive revisited: mastery and satisfaction’

In this commentary on Paul Denis's paper ‘The drive revisited: mastery and satisfaction’, the author defends the idea of a plurality of metapsychologies that must be contrasted with and distinguished from each other while avoiding incompatible translations between models. In this connection he presents various theoretical approaches to aggression and the death drive, and demonstrates the differences between the drive model and the model underlying the theory of internalized object relations. The author holds that the concept of the internal object differs from Freud's notion of the representation (Vorstellung). He also considers that the imago as defined by Paul Denis in fact corresponds to the concept of the internal object. Lastly, he addresses the complex issue of listening to archaic forms of psychic functioning and their non‐discursive presentation within the analytic process, which affects the transference‐countertransference link.     

Destruction reconceived: On Winnicott's ‘The Use of an Object and Relating through Identifications’

‘The Use of an Object and Relating through Identifications’ is a landmark contribution that I find very difficult to write about because so much of what lies at its core is merely suggested. It is necessary for the reader not only to read the paper, but also to write it. In my reading/writing of the paper, the mother becomes real for the infant in the process of his actually destroying her as an external object (destroying her sense of herself as an adequate mother), and his perceiving that destruction. She also becomes a real external object for the infant in the process of his experiencing the psychological work involved in surviving destruction, a form of work that does not occur in the world of fantasied objects. The analyst or mother may not be able to survive destruction. It is essential that the analyst be able to acknowledge to himself his inability to survive and, if necessary, to end the analysis because of the very damaging effects for both patient and analyst of prolonged experience of this sort. The author presents clinical discussions of analyses in which the analyst survives destruction and is unable to survive destruction.     

Visual object imagery and autobiographical memory: Object Imagers are better at remembering their personal past

In the present study we examined whether higher levels of object imagery, a stable characteristic that reflects the ability and preference in generating pictorial mental images of objects, facilitate involuntary and voluntary retrieval of autobiographical memories (ABMs). Individuals with high (High-OI) and low (Low-OI) levels of object imagery were asked to perform an involuntary and a voluntary ABM task in the laboratory. Results showed that High-OI participants generated more involuntary and voluntary ABMs than Low-OI, with faster retrieval times. High-OI also reported more detailed memories compared to Low-OI and retrieved memories as visual images. Theoretical implications of these findings for research on voluntary and involuntary ABMs are discussed.     

Smelling matter

While the objects of olfaction are intuitively individuated by reference to the ordinary objects from which they arise, this intuition does not accurately capture the complex nature of smells. Smells are neither ordinary three-dimensional objects, nor Platonic vapors, nor odors. Rather, smells are the molecular structures of chemical compounds within odor plumes. Molecular Structure Theory is offered as an account of smells, which can explain the nature of the external object of olfactory perception, what we experience as olfactory objects, and what determines the olfactory quality of smells by which we can demarcate the spatiotemporal boundaries of smells.     

Attentional Predictors of 5‐month‐olds' Performance on a Looking A‐not‐B Task

In the first year of life, the ability to search for hidden objects is an indicator of object permanence and, when multiple locations are involved, executive function (i.e. inhibition, cognitive flexibility and working memory). The current study was designed to examine attentional predictors of search in 5‐month‐old infants (as measured by the looking A‐not‐B task), and whether levels of maternal education moderated the effect of the predictors. Specifically, in a separate task, the infants were shown a unique puppet, and we measured the percentage of time attending to the puppet, as well as the length of the longest look (i.e., peak fixation) directed towards the puppet. Across the entire sample (N = 390), the percentage of time attending to the puppet was positively related to performance on the visual A‐not‐B task. However, for infants whose mothers had not completed college, having a shorter peak looking time (after controlling for percentage of time) was also a predictor of visual A‐not‐B performance. The role of attention, peak fixation and maternal education in visual search is discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Religion,reason and non-directive teaching: a reply to Trevor Cooling

In other work I have argued that decisions about what to teach directively and what non-directively should be governed by an epistemic criterion. Trevor Cooling has recently advanced some objections to my defence and application of the epistemic criterion and proposed an alternative to it. Here I reply to his objections and comment on his proposed alternative.     

Modeling Martin-Löf type theory in categories

We present a model of Martin-Löf type theory that includes both dependent products and the identity type. It is based on the category of small categories, with cloven Grothendieck bifibrations used to model dependent types. The identity type is modeled by a path functor that seems to have independent interest from the point of view of homotopy theory. We briefly describe this modelʼs strengths and limitations.
