Words and possible words in early language acquisition

In order to acquire language, infants must extract its building blocks—words—and master the rules governing their legal combinations from speech. These two problems are not independent, however: words also have internal structure. Thus, infants must extract two kinds of information from the same speech input. They must find the actual words of their language. Furthermore, they must identify its possible words, that is, the sequences of sounds that, being morphologically well formed, could be words. Here, we show that infants’ sensitivity to possible words appears to be more primitive and fundamental than their ability to find actual words. We expose 12- and 18-month-old infants to an artificial language containing a conflict between statistically coherent and structurally coherent items. We show that 18-month-olds can extract possible words when the familiarization stream contains marks of segmentation, but cannot do so when the stream is continuous. Yet, they can find actual words from a continuous stream by computing statistical relationships among syllables. By contrast, 12-month-olds can find possible words when familiarized with a segmented stream, but seem unable to extract statistically coherent items from a continuous stream that contains minimal conflicts between statistical and structural information. These results suggest that sensitivity to word structure is in place earlier than the ability to analyze distributional information. The ability to compute nontrivial statistical relationships becomes fully effective relatively late in development, when infants have already acquired a considerable amount of linguistic knowledge. Thus, mechanisms for structure extraction that do not rely on extensive sampling of the input are likely to have a much larger role in language acquisition than general-purpose statistical abilities.     

Personal and social aspects of professional identity.: An extension of Marcia's identity status model applied to a sample of university students

The study proposed an extension of Marcia's identity status model based on validation of the Professional Identity Status Questionnaire (PISQ-5d), a scale able to measure both intra-individual and intergroup processes connected with the development of a professional identity in university students. The aims were to prove the construct validity of the PISQ-5d, to determine the appropriate number of identity statuses, and to assess the concurrent validity of the identity statuses considering both job-related and academic factors. In this study, 477 university students completed a questionnaire with the PISQ-5d scale; 220 also completed the measures of work values; and 168 completed the measures of student self-esteem and self-efficacy, academic motivation, and grades. Results confirmed the expected five-dimensional structure of the PISQ-5d and the scale's effectiveness at differentiating five types of identity status. Relationship between professional identity status and job-related and academic factors showed that the students with achievement or foreclosure identities had higher scores on measures of academic self-esteem and intrinsic work value and had lower scores for intention to leave university. Implications in terms of considering the PISQ-5d scale a useful tool for the evaluation of professional identity construction processes in university students will be discussed.     

Gulliver’s Eggs: Why Methods are not an Issue of Qualitative Research in Cultural Psychology

The future of qualitative methods regards the kind of object cultural psychology is interested and the kind of questions it can ask. I propose that the object should be experiencing, understood as a complex whole, consisting of lived-by action and counter-action, that is contextual inter-action with the world in the form of an experiencing subject and otherness. The kind of questions cultural psychology can ask is instead related to the epistemological status attributed to both researcher and participant. Probably few scholars such as Vygotsky, Piaget and Lewin understood to what extent experiencing is always changing, because the relationship between mind, alterity and culture is co-generative. This also implies a relativization and a decentralization of the psychology’s perspective. Finally, I provide some examples from the history of psychology and some suggestions to work at the level of such complexity by using methods that can work with complex objects such as products of human activity (e.g., art, literature, architecture, etc.).     

Show me the product,show me the model: Effect of picture type on attitudes toward advertising

We suggest that a consideration of consumer self-evaluations is fundamental to understanding the conditions under which it is more advantageous to present person or product pictures in print advertisements. We build on the basic human motives of self-enhancement and self-verification to propose that the specific self-esteem level of consumers, in the domain relevant for the category, differentially affects their responses to picture type. Specifically, for consumers with low (high) domain-specific self-esteem, depicting a product (person) in the advertisement enhances attitudes toward the advertisement more than depicting a person (product). In two studies, we demonstrate the proposed matching relationships using two different domains of consumer self-evaluation: appearance self-esteem and academic self-esteem. We also show that increased and more fluent generation of self-related mental imagery drives the observed improvement in attitudes toward the advertisement. Our findings suggest direct implications for advertising design.     

How School can Teach Civic Engagement Besides Civic Education: The Role of Democratic School Climate

Civic engagement, defined as involvement in community life, is influenced by reciprocal relationships between individuals and contexts and is a key factor that contributes to positive youth development. The present study evaluates a theoretical model linking perceived democratic school climate with adolescent civic engagement (operationalized as civic responsibility and intentions for future participation), taking into account the mediating role of civic discussions and perceived fairness at school. Participants were 403 adolescents (47.9 % male) ranging in age from 11 to 15 years old (mean age = 13.6). Path analysis results partially validated the proposed theoretical model. Higher levels of democratic school climate were associated with higher levels of adolescent civic responsibility; the association was fully mediated by civic discussions and perceived fairness at school. Adolescents’ civic responsibility, then, was positively associated with a stronger intention to participate in the civic domain in the future.     

Say What? On Grice On What Is Said

Abstract: In this paper I argue that there is a very important, though often neglected, dissimilarity between the two Gricean conceptions of ‘what is said’: the one presented in his William James Lectures and the one sketched in the ‘Retrospective Epilogue’ to his book Studies in the Way of Words. The main problem lies with the idea of speakers' commitment to what they say and how this is to be related to the conventional, or standard, meaning of the sentences uttered in the act of saying. Since the later notion of ‘what is said’, or ‘dictiveness’, is claimed to be logically independent from ‘formality’ (roughly, conventional meaning), Grice seems to maintain that there are cases in which content that is not expressed by a sentence in a context may nevertheless count as what is said. I propose an account of what is said that brings together the two apparently irreconcilable approaches. The price to be paid for a Gricean, however, is to accept a duality of behaviour between (natural language counterparts of) logical constants and logical variables.     

The Graph Conception of Set

The non-well-founded set theories described by Aczel (1988) have received attention from category theorists and computer scientists, but have been largely ignored by philosophers. At the root of this neglect might lie the impression that these theories do not embody a conception of set, but are rather of mere technical interest. This paper attempts to dispel this impression. I present a conception of set which may be taken as lying behind a non-well-founded set theory. I argue that the axiom AFA is justified on the conception, which provides, contra Rieger (Mind 109:241–253, 2000), a rationale for restricting attention to the system based on this axiom. By making use of formal and informal considerations, I then make a case that most of the other axioms of this system are also justified on the conception. I conclude by commenting on the significance of the conception for the debate about the justification of the Axiom of Foundation.     

I play doh: The art of plasticine in the process of adolescent subjectivation

Pre‐adolescents' difficulty in portraying and communicating the internal turmoil to which puberty subjects them, both through the immaturity of their psychic functions and through the conflict between display and secrecy, presents a constant challenge to the analyst. A technical solution for making the process of subjectivation more pleasant may be found in modelling with Play Doh, a game/non‐game which is not age‐specific, an expressive form capable of evoking in the analytic field fantasies and representations that are otherwise only accessible with difficulty. This paper aims to present some reflections on the characteristic features of the Play Doh game in the session, with particular regard to work with patients between 10 and 14 years old who are in the midst of the process of adolescent subjectivation. The paper examines the clinical history of a young adopted boy who was able to develop the ability to dream his own experience and to portray internal experiences which had previously been unrepresentable.     

Individuals with intellectual and developmental disabilities: Do educators assign them a fully human status?

The present research investigates the humanity attributions to individuals with intellectual and developmental disabilities (IDD). In three studies, professional educators, who worked in day‐care or community centers, were examined. Humanity attributions were assessed using emotion‐based and trait‐based measures. As expected, individuals with IDD were denied a fully human status: they were perceived as having more non‐uniquely than uniquely human attributes. Furthermore, a lower human status was assigned to individuals with IDD in relation to educators. We also discovered that humanity attributions, but not attitudes, were related to approach/avoidance responses. Altogether, findings show the importance of considering humanity perceptions in the study of social relationships of individuals with IDD. Dehumanizing perceptions can explain the differential treatment these individuals face in various social settings.
