Determinants of lexical access in speech production: Role of word frequency and age of acquisition

The main determinants of lexical access in speech are considered to be a word's age of acquisition (AoA) and its frequency of occurrence in a speaker's experience. It is unclear whether and how these variables interact, although they are commonly observed to be correlated, for the few studies that address the issue have reported inconsistent findings. An influential view of AoA in lexical processing (Ellis and Lambon Ralph, 2000) predicts stronger frequency effects for items acquired later in life than for those acquired at an early age. Five experiments were designed to investigate the possible interaction of AoA and frequency effects in speech. We found that the interaction between word frequency and AoA was not robust and that, contrary to expectation, the effect of word frequency was greater for words acquired earlier in life than for those acquired later. The implications of our findings are discussed.     

Lost in Translation? The Need for ‘Upstream Engagement’ with Nanotechnology on Trial

Nowadays, the criticism of the so-called ‘deficit model’ and the need for ‘upstream engagement’ in science and technology are becoming part of the master narratives of public policies in many countries, especially concerning nanotechnology. This may be considered as a major success for STS scholars, whose research results have largely contributed to this change, especially those concerning the GMO controversies. Some STS scholars thus move from a position of distant and critical observers to the role of experts in social engineering or advisers of policy-makers. However, in their enthusiasm concerning the expected benefits of upstream engagement, institutions, TA practitioners and social scientists seem to ignore some important limitations as well as the implicit framing assumptions of the concept. Based on an experience made by a group of social scientists in the Grenoble area—one of the major ‘nanodistricts’ in Europe—our paper shows that the ‘upstream engagement’ concept is still embedded in a linear model of innovation and is not very useful to anyone pursuing the co-production of innovations. It is especially true when socio-technical networks are already aligned by powerful actors and a worldwide agenda as in the case of nanotechnology. In order to give an opportunity for public engagement to have a larger impact on decision-making, we propose an alternative approach, which combines Actor–Network Theory (ANT), as an analytical tool, with the reflexive and ongoing implementation of public participation. Public engagement is probably one of the critical loci where STS scholars must reflect on the articulation between the knowledge they produce and public policies in action.     

Educating Evolutionary Co-Leadership to Embody a Radically New Development Paradigm

The purpose here is to explore why and how to develop an emerging form of integral leadership—called evolutionary co-leadership—that is responsibly dedicated to the co-evolution of life and humanity on Planet Earth. After offering some fresh distinctions about leadership, this article calls for a shift to a radically new development paradigm, and identifies key qualities and practices of evolutionary co-leadership. It then shares some views on the multiplying effects of an integral approach to co-leadership development—in the context of transforming education—and concludes with some avenues to disseminate this emerging leadership form, mainly to deal constructively with what Barbara Marx Hubbard (2001) calls the current “birthing pains” of a new civilization.     

Drawing as a means of communication at the initial interview with children with cancer

Cancer is always associated with distress and fear. In working with children who have cancer, a trusting relationship and meaningful dialogue often cannot be established by talking on its own. Drawings may offer an opportunity for children to express their feelings without giving up resistance completely. This paper summarizes the aims of the first interview with an ill child, one of its main purposes being the evaluation of the children's and their family's resources to cope with the strains of the illness. The meaning of drawings in this process is discussed in two case reports.     

Threat and Right‐Wing Attitudes: A Cross‐National Approach

Threat relates to right‐wing ideological attitudes at the individual level. The present study aims to extend this relationship to the national level. More specifically, in a sample of 91 nations, we collected country‐level indicators of threat (including inflation, unemployment, gross national product, homicide rate, and life expectancy). Moreover, we analyzed data from the European and World Value Survey (total N = 134,516) to obtain aggregated country‐level indicators for social‐cultural and economic‐hierarchical right‐wing attitudes for each of these countries. In accordance with previous findings based on the individual level, a positive relationship between threat indicators and right‐wing attitudes emerged. This relationship was stronger than what was usually reported at the individual level. In the discussion, we focus on the mutually reinforcing influence at the individual and national levels in terms of right‐wing attitudes.

Keep the fire burning: Reciprocal gains of basic need satisfaction,intrinsic motivation and innovative work behaviour

Drawing on insights from self-determination theory, we explored the dynamic relationship between intrinsic motivation and innovative work behaviour (IWB) over time. Specifically, we investigated how basic need satisfaction influences IWB through its effect on intrinsic motivation and how IWB in turn affects basic need satisfaction as measured the next day (i.e., a reciprocal relationship). The current study used a longitudinal design comprising a 6-day period and relied on multi-source data from 76 students in industrial product design and electronic engineering who participated in an innovation boot camp. In general, results provided support for the mediating role of intrinsic motivation in the relationship between basic need satisfaction and IWB, as well as the reciprocal relationship between basic need satisfaction and IWB.     

Objective age-of-acquisition (AoA) norms for a set of 230 object names in French: Relationships with psycholinguistic variables,the English data from Morrison et al. (1997), and naming latencies

Picture naming speed is strongly influenced by the age of acquisition (AoA) of words. Most studies of AoA have relied on adults' AoA ratings. However, objective AoA has been found to be a stronger determinant of picture naming latencies. Whereas objective AoA norms for words have been collected for some language communities, no objective AoA measures for words were previously available in French. The study provides objective AoA norms for a set of 230 object names following the procedures used by Morrison, Chappell, and Ellis (1997) to collect objective AoA measures in English. The relationships between objective AoA measures, rated AoA, other variables used in psycholinguistic experiments (name agreement, image agreement, conceptual familiarity, etc.), the English data collected by Morrison et al., and naming latencies are analysed and discussed. In addition, reanalyses of data on picture naming latencies (Bonin, Chalard, Méot, & Fayol, 2002) with the use of objective AoA norms are provided. Stepwise multiple analyses show that objective AoA is a stronger determinant of (spoken and written) naming latencies than rated AoA, whereas objective word frequency is not a reliable independent determinant and does not interact reliably with AoA in any of the analyses.
