Young children interpret number gestures differently than nonsymbolic sets

Researchers have long been interested in the origins of humans’ understanding of symbolic number, focusing primarily on how children learn the meanings of number words (e.g., “one”, “two”, etc.). However, recent evidence indicates that children learn the meanings of number gestures before learning number words. In the present set of experiments, we ask whether children's early knowledge of number gestures resembles their knowledge of nonsymbolic number. In four experiments, we show that preschool children (n = 139 in total; age M = 4.14 years, SD = 0.71, range = 2.75–6.20) do not view number gestures in the same the way that they view nonsymbolic representations of quantity (i.e., arrays of shapes), which opens the door for the possibility that young children view number gestures as symbolic, as adults and older children do.

Highlights

• Children were more accurate when enumerating briefly-presented number gestures than arrays of shapes, with a shallower decline in accuracy as quantities increased.
• We replicated this finding with arrays of shapes that were organized into neat, dice-like configurations (compared to the random configurations used in Experiment 1).
• The advantage in enumerating briefly-presented number gestures was evident before children had learned the cardinal principle.
• When gestures were digitally altered to pit handshape configuration against number of fingers extended, children overwhelmingly based their responses on handshape configuration.

     

Exploring religious and/or spiritual identities: part 1 – assessing relationships with health

ABSTRACT

There is considerable debate about the distinction between being religious and being spiritual. It is time to move beyond this issue to an examination of the health-related implications of being religious and/or spiritual. Three health outcomes are used in this study: self-rated health, depressive symptoms, and alcohol use. The data are from a large nationwide random probability survey of adults of all ages who reside in the United States (N?=?2,876–2,883). Four self-identified categories of religiousness/spirituality are examined: religious and spiritual, spiritual only, not religious/not spiritual, and religious only. Tests are performed to see if membership in each category offsets the noxious effects of lifetime trauma on the health-related outcomes. A clear pattern emerges from the data. Lifetime trauma is associated with less favourable health ratings, more symptoms of depression, and greater alcohol consumption. However, these relationships are substantially stronger among people who say they are religious only.     

A Cross-Cultural Look at Assessment Center Practices: Survey Results from Western Europe and North America

No recent survey documents assessment center (AC) practices across several countries. Therefore, we analyse AC practices in a sample of 97 organisations from nine countries in Western Europe and North America. We report findings regarding job analysis, dimensions, exercises, additional diagnostic methods, use of technology, assessor characteristics, contents and methods of assessor training, observational systems, information provided to participants, evaluation of participants' reactions, data integration, characteristics of feedback, and features after the AC. Finally, we compare our results with prior findings to identify trends over time and point out features of ACs that could be improved.
Face aux défis que soulèvent les centres d'évaluation (AC) dans les organisations internationales, nous proposons un modèle qui rend compte des variations transculturelles dans ces pratiques, variations relevant de données individuelles (la motivation et la qualification des experts en resources humaines), de conditions culturelles (le « contrôle de l'incertitude >> et la « distance hiérarchique >>) et de réalités institutionnelles (des differences dans le niveau officiel de collectivisme et des divergences en ce qui concerne les normes légales et les lois régissant l'emploi). Ce modèle est exploité pour expliquer les différences dans la planification, l'exécution et l'évaluation des AC dans des organisations situées dans neuf pays d'Europe de l'ouest et d'Amérique du nord. Nous mettons aussi en evidence des tendances sur le long terme dans les pratiques des AC et discutons de l'amélioration de ces pratiques et de l'orientation des futures recherches dans ce domaine.
