Observing social signals in scaffolding interactions: how to detect when a helping intention risks falling short

In face-to-face interactions, some social signals are aimed at regulating scaffolding processes, by which more knowledgeable people try to help less knowledgeable ones, to enable them to learn new concepts or skills (Vygotsky 1978). Observing face-to-face scaffolding interactions might not only allow us to grasp a large variety of these highly interesting social signals but may also be useful for the sake of scaffolding processes themselves. It often happens, in fact, that the empowering intentions implicit in these processes end up falling short, if the social signals regulating this specific kind of face-to-face interaction are misunderstood. Interestingly, many of these misunderstood aspects are related to the recipient's role. Indeed, attention is usually focused on the behavior of those imparting the knowledge, while skills already mastered by the learners, as well as their feedback, tend not to be taken as much into account. For the purpose of exploring the often very subtly nuanced social signals regulating on-going scaffolding processes in real-life interactions, an example of a methodological tool is presented: one already used to observe the interactions of dyads of Italian primary school teachers and their pupils, and mothers and their children. The article leads to two main conclusions: that the results of instances of scaffolding may be predicted as to their success or otherwise simply by telescoping crucial social signals during the scaffolding's initial phases, and that when helpers disregard these signals the effects of their actions may be detrimental or even humiliating for the receivers, notwithstanding the helper's intentions.     

A response to Nguyen’s article, ‘Identification: A qualitative study of the experiences of bilingual therapists with their monolinguals and bilingual clients’

Noticing a certain lack of reflections directly related to language per se, I emphasise and discuss the importance of language issues in any bilingual or multilingual therapy. I try to illustrate this both with some of the existing literature on the subject and by offering my own take on some of the comments made by the interviewees.     

Meaning Coconstruction in Group Counseling: The Development of Innovative Moments

This study discusses a model of group counseling, the narrative mediation path (NMP), which is a unique narrative, multimodal approach that combines four narrative modes (metaphoric, iconographic, writing, and bodily) and the narrative group. The purpose of the NMP is to foster reflexive processes with underachieving university students and to improve their academic performance. The study analyzes a single case of group counseling for seven underachieving economics students at an Italian university and the process of meaning construction among NMP narrative modes and the follow-up session. It applies the innovative moments coding system, a reliable method for studying change by tracking narrative innovations in sessions. More specifically, we focus on how innovative moments (IMs: action, reflection, protest, and reconceptualization) evolve during the four different narrative modes and the follow-up session. The findings suggest that the NMP fosters narrative innovations, mainly of a reflexive nature (reflection and reconceptualization). Moreover, during counseling and the follow-up session, the pattern of change is primarily characterized by reconceptualization IMs, the most complex form of narrative innovation.     

The effects of ongoing activity on time estimation in prospective remembering

Two experiments examined whether time‐based prospective memory performance is influenced by the continuous or discontinuous nature of an ongoing activity. The first experiment demonstrated that prospective memory performance was not influenced by the engagement in continuous or discontinuous ongoing activity. The second experiment demonstrated that a discontinuous ongoing activity negatively affected prospective memory performance when participants had to execute two time‐based tasks for which the retention intervals partially overlapped. The results suggest that when individuals are engaged in multiple time‐based tasks, a general timing disruption occurs, with a proactive interference effect resulting in costs that are detrimental to prospective timing.

Interpolation in non-classical logics

We discuss the interpolation property on some important families of non classical logics, such as intuitionistic, modal, fuzzy, and linear logics. A special paragraph is devoted to a generalization of the interpolation property, uniform interpolation.

Do fish count? Spontaneous discrimination of quantity in female mosquitofish

The spontaneous tendency to join the largest social group was used to investigate quantity discrimination in fish. Fish discriminated between shoals that differed by one element when the paired numbers were 1vs2, 2vs3 and 3vs4, but not when 4vs5 or larger. Using large numerosities (>4), the ability to discriminate between two numbers improved as the numerical distance between them increased and a significant discrimination was found only with ratios of 1:2 or smaller (4vs8, 8vs16 and 4vs10). Experiments to control for non-numerical variables evidenced the role played by the total area of stimuli with both large and small numerosities; the total quantity of movement of the fish within a shoal appeared also important but only when large numerosities were involved. Even though the pattern of discrimination exhibited by female mosquitofish is not fully consistent with any of the existing models of quantity representation, our results seem to suggest two distinct mechanisms in fish, one used to compare small numbers of objects and one used when larger numerosities are involved.     

Emotion and ethics: An inter-(en)active approach

In this paper, we start exploring the affective and ethical dimension of what De Jaegher and Di Paolo (Phenomenology and the Cognitive Sciences, 6:485–507, 2007) have called ‘participatory sense-making’. In the first part, we distinguish various ways in which we are, and feel, affectively inter-connected in interpersonal encounters. In the second part, we discuss the ethical character of this affective inter-connectedness, as well as the implications that taking an ‘inter-(en)active approach’ has for ethical theory itself.     

Semantic trees for Dummett's logic LC

The aim of this paper is to provide a decision procedure for Dummett's logic LC, such that with any given formula will be associated either a proof in a sequent calculus equivalent to LC or a finite linear Kripke countermodel.
