Testing primary‐school children's understanding of the nature of science

Understanding the nature of science (NOS) is a critical aspect of scientific reasoning, yet few studies have investigated its developmental beginnings and initial structure. One contributing reason is the lack of an adequate instrument. Two studies assessed NOS understanding among third graders using a multiple‐select (MS) paper‐and‐pencil test. Study 1 investigated the validity of the MS test by presenting the items to 68 third graders (9‐year‐olds) and subsequently interviewing them on their underlying NOS conception of the items. All items were significantly related between formats, indicating that the test was valid. Study 2 applied the same instrument to a larger sample of 243 third graders, and their performance was compared to a multiple‐choice (MC) version of the test. Although the MC format inflated the guessing probability, there was a significant relation between the two formats. In summary, the MS format was a valid method revealing third graders' NOS understanding, thereby representing an economical test instrument. A latent class analysis identified three groups of children with expertise in qualitatively different aspects of NOS, suggesting that there is not a single common starting point for the development of NOS understanding; instead, multiple developmental pathways may exist.     

The influence of mood on the intensity of emotional responses: Disentangling feeling and knowing

The results of three experiments suggest that pre-existing mood increases the intensity of affectively congruent emotions while dampening the intensity of incongruent emotions independent of attributional knowledge. This result was obtained using a new method for inducing mood states unobtrusively and with minimal or no cognitive concomitants. The results of Experiment 1 revealed that for participants who were exposed to positive feedback a pre-existing positive mood led to stronger feelings of pride in comparison to negative mood. The results of Experiments 2 and 3 suggest that pre-existing mood directly influences the experience of subsequently elicited emotions independent of what one knows about the causes of this feeling. When participants were required to differentiate between the funniness of a cartoon and their subjective humour response, mood influenced only the latter judgement (Experiment 2). In Experiment 3, reminding participants of the mood induction resulted in a contrast effect in judging the funniness of a cartoon. However, the pre-existing mood continued to exert an assimilation effect on the overt mirth response. In conclusion, these results suggest that the feeling and knowledge component are partly independent bases of emotional responses.     

Adult Parent–Child Relationships: Relationship Quality, Support, and Reciprocity

A partir du modèle de la solidarité intergénérationnelle de Bengston ( Bengston & Roberts, 1991 ), on a étudié, chez 265 femmes entre deux âges vivant en Allemagne, les interrelations entre leurs valeurs familiales, leur perception de qualité de la relation avec leurs parents, le soutien qu’elles disent leur apporter et recevoir de leur part, ainsi que leur appréhension de l’entraide entre les générations. On s’est aussi demandé si l’aide apporté aux parents et la réciprocité perçu étaient en rapport avec la charge que les filles ressentaient suite au soutien accordé. Les données des diverses rubriques, fournies par les sujets, ont été traitées avec des analyses de régression logistiques multiple et multinomiale. Les analyses ont débouché sur des liaisons positives entre les valeurs familiales, la qualité des relations et le soutien aux parents. La réciprocité perçue était reliée aux aides mutuelles entre les générations et un soutien déséquilibré avait des effets négatifs sur la qualité de la relation. La charge ressentie pouvait ­être prédite à partir de la réciprocité perçue et de l’importance de l’aide. Cependant, sont apparus des modèles corrélationnels spécifiques dépendant à la fois du type d’aide et du niveau d’importance relatif du père et de la mère. Les résultats sont discutés dans le contexte du sens de la réciprocité et des obligations familiales dans une culture occidentale. In accordance with Bengtson's model of intergenerational solidarity (e.g. Bengtson & Roberts, 1991 ), the interrelations between adult daughters’ family values, their perception of the relationship quality with their parents, the support they reported to give to and to receive from their parents, and their perception of reciprocity in intergenerational support exchange were investigated for N= 265 middle‐aged women in Germany. It was also asked whether the support given to parents and perceived reciprocity are related to daughters’ felt burden as a result of their support. Cross‐sectional, self‐report data were examined with multiple and multinomial logistic regression analyses. The analyses revealed positive relations between family values, relationship quality, and support to parents. Perceived reciprocity was associated with the exchange of intergenerational support, and imbalance in support had negative effects on the relationship quality. Felt burden was predicted by the extent of support and the perceived reciprocity. However, specific correlational patterns depending on the kind of support as well as differences in the importance of mother and father occurred. The findings are discussed against the background of the meaning of family obligations and reciprocity in a Western culture.     

Children’s prior experiences of their successes and failures modulate belief alignment

ABSTRACT

An ability to flexibly learn from others while at other times relying upon one’s own judgements is an important adaptive human capacity. The present research investigated how others’ epistemic states and prior experience of their own independent ability in a given task modulate young children’s selective learning. In particular, we asked whether 4-year-old children’s judgement concerning the location of a hidden object is modulated both by an informant’s knowledge states and by the absence/presence of a prior experience with a particular task. We found that the children were more likely to align their judgement according to the informant’s verbal report when the informant was knowledgeable than when she was ignorant – but only when they had explicitly experienced their own incapability to accurately guess an object’s location. The findings suggest that 4-year-old children are able to combine their own experience with others’ input to make their judgement.
