Even in adults,written production is still more costly than oral production

The aim of this research is to show that the mechanical demands of writing continue to affect the characteristics of produced texts in adults under certain situations of cognitive overload. The study reported here is intended to demonstrate that the quality of the text produced by educated adults falls when production is performed in the written rather than in the spoken mode, but only when the elements on the basis of which the texts are to be produced are difficult to relate to one another. In this view, we compared performance in a text production span task in either the oral or the written mode. This task consisted of presenting sets of words, semantically linked or not, from which adults had to produce texts including the words in the set. The results showed that neither the production mode nor the extent of the relationship between the items influenced the number of words recalled. By contrast, the number of ideas elaborated and the coherence of the produced texts are lower when the supplied items are difficult to link and when production is in the written mode. These results are interpreted in the framework of capacity theories in production. They suggest that the cost of managing written production is not always negligible in well‐educated adults. When they have to produce texts on the basis of provided elements that are only weakly associated with one another in the written mode, the residual capacity necessary either to maintain and organise the information in working memory, or to adopt a strategic approach to the composition of the texts, is insufficient because the cost of this elaboration must be added to that of the management of the written production.     

Delay discounting: Interactions between personality and cognitive ability

Delay discounting describes the extent to which the value of a reward decreases as the delay to obtaining that reward increases. Lower discounting rates predict better outcomes in social, academic, and health domains. The current study investigates how personality and cognitive ability interact to predict individual differences in delay discounting. Extraversion was found to predict higher discounting rates at the low end of the cognitive distribution, while emotional stability was found to predict lower discounting rates at the high end of the cognitive distribution. These findings support recent models of discounting behavior and suggest that personality and cognitive ability interact in shaping decision making.     

Two-to-three-year-old children's interactions with peers in child-care centres: Effects of spatial distance to caregivers

In child-care centres, the influence of caregivers on the development of peer interactions seems ambivalent and mixed results are reported in the literature. Adopting an environmental approach, we examined the effects of the caregivers’ spatial proximity on children's social behaviour. The study was carried out with 175 children (18-40 months) in 12 child-care-centre groups. Children's behaviours were observed during free plays, and both children and caregivers’ locations were recorded. When peers were nearby, children's social behaviours were compared when they were in the immediate proximity (within 2 m) and out of the immediate proximity of a caregiver. Results show that in the latter situation children spend substantially more time addressing social overture to peers and interacting with them; positive interactions with peers show a particularly marked difference. This pattern of results is exhibited by the greater part of the children. Whatever the child-care-centre group, the age subgroup or the gender considered similar results are found. Results also demonstrate that when children are in the immediate proximity of caregivers they are socially oriented towards the attractive adult partners rather than towards peers.     

A national survey of U.S. statutes on juvenile transfer: implications for policy and practice

A survey of the statutes on juvenile transfer and cecertification in the U.S. federal and 50 state jurisdictions, and the District of Columbia, was performed. Relevant information was obtained on the procedures in each jurisdiction by which a juvenile can be tried in criminal court, whether there are applicable decertification (“transfer back”) procedures in jurisdictions permitting criminal court processing through automatic file or prosecutorial discretion, and the burden and allocation of proof in relevant proceedings. We also identified four criteria relevant to the mental, emotional, and developmental functioning of juveniles that are used in various jurisdictions in making transfer and decertification decisions: treatment needs and amenability, risk assessment of future criminality, the presence of mental retardation or mental illness, and certain kinds of offense characteristics. The majority of jurisdictions now allow 14-year-old juveniles to be tried in criminal court. Treatment needs/amenability and risk assessment are set forth as criteria relevant to transfer in the majority of jurisdictions as well, with the presence of mental retardation or mental illness explicitly relevant in a small number of jurisdictions. The patterns of these findings are discussed in their implications for social policy and for the forensic mental health assessment of juvenile transfer and decertification, with needed areas of research identified within each. ©1997 John Wiley & Sons, Ltd.

Breast cancer: The intention to have a mammography and a clinical breast examination - application of the theory of planned behavior

Abstract

The purpose of these cross sectional studies was to identify the psychosocial factors explaining women's intention to have a mammography within the next two years and their intention to have a clinical breast examination (CBE) by a professional within the next year. Two random samples of women aged 40–69 years (n_a = 354, n_b = 344) completed a self-administered questionnaire that investigated theoretical constructs of the theory of planned behavior. The results of structural equation modeling showed that subjective norms and perceived behavioral control explained 81 % of the variance in intention of having a mammography. Sixty-five percent (65%) of the variance in intention of having a CBE was explained by attitude and perceived behavioral control. In conclusion, women need to be better informed, have better skills to overcome psychological and physical barriers in performing preventive breast behaviors, and promotion of preventive breast cancer methods should consider people significant for women.     

The Influence of Predeployment Training on Coordination in Multinational Headquarters: The Moderating Role of Organizational Obstacles to Information Sharing

Coordination is critical to the success of multinational military operations and may be fostered by predeployment training. We argue that whether such training is related to a high degree of perceived coordination at the individual level is likely to depend on whether individuals experience a low degree of organizational obstacles to information sharing. We examined this using data from the North Atlantic Treaty Organization (NATO) Kosovo Force headquarters (survey: n = 131). We controlled for whether it was the participants’ first deployment, the participants’ background (military or civilian), the amount of time spent in the headquarters by participants, whether differences pertaining to culture and opinions were valued by the organization, the quality of supervisor/subordinate relationships, and the degree of national cultural obstacles to information sharing. The results showed no significant direct effects on coordination from 3 different training configurations: national training, multinational training, and a combination of national and multinational training. However, we found a negative direct effect from organizational obstacles to information sharing on coordination, and support for organizational obstacles to information sharing as negatively moderating the multinational predeployment training and coordination relationship. Qualitative interviews (n = 14) indicated that informal information sharing, and the problems exchanging information from tactical to operational levels could hinder coordination. Interventions to foster coordination could benefit from a focus on multinational training and lowering organizational obstacles to information sharing. Our findings contribute to more precisely pinpointing the types of training that are useful in multinational operations, as well as the factors upon which training transfer is contingent.     

Visual discrimination of species in dogs (Canis familiaris)

In most social interactions, an animal has to determine whether the other animal belongs to its own species. This perception may be visual and may involve several cognitive processes such as discrimination and categorization. Perceptual categorization is likely to be involved in species characterized by a great phenotypic diversity. As a consequence of intensive artificial selection, domestic dogs, Canis familiaris, present the largest phenotypic diversity among domestic mammals. The goal of our study was to determine whether dogs can discriminate any type of dog from other species and can group all dogs whatever their phenotypes within the same category. Nine pet dogs were successfully trained through instrumental conditioning using a clicker and food rewards to choose a rewarded image, S+, out of two images displayed on computer screens. The generalization step consisted in the presentation of a large sample of paired images of heads of dogs from different breeds and cross-breeds with those of other mammal species, included humans. A reversal phase followed the generalization step. Each of the nine subjects was able to group all the images of dogs within the same category. Thus, the dogs have the capacity of species discrimination despite their great phenotypic variability, based only on visual images of heads.
