An Investigation of the Relationship between Age,Achievement, and Creativity in Mathematics

In this exploratory study, I investigate the relationship between age, knowledge, and creativity in mathematics, by looking at to what extent does grade level, controlled for mathematical achievement, influence mathematical creativity and what characterizes the relationship between grade level, mathematical achievement and mathematical creativity. This was accomplished in two steps. In the first part, 301 students, 184 grade eight students and 117 grade eleven students, were given a creative mathematics test. A 3 × 2 ANOVA indicates that the older students were more creative; however, there was a significant interaction effect between grade level and achievement in mathematics on mathematical creativity. In the second part, an inductive content analysis was performed on the solutions of high achievers in grade eleven and grade eight. The results indicate that high achievers in grade eight are more creative than high achievers in grade eleven, but the nature of the task mediates the relationship between creativity and knowledge.     

Younger adults report more distress and less well-being: A cross-cultural study of event centrality,depression, post-traumatic stress disorder and life satisfaction

The extent to which highly emotional autobiographical memories become central to one's identity and life story influences mental health. Young adults report higher distress and lower well-being, compared with middle-aged and/or older adults; whether this replicates across cultures is still unclear. First, we provide a review of the literature that examines age-differences in depression, post-traumatic stress disorder (PTSD), and life satisfaction in adulthood across cultures. Second, we report findings from a cross-cultural study that examined event centrality of highly positive and negative autobiographical memories along with symptoms of depression and PTSD, and levels of life satisfaction in approximately 1000 young and middle-aged adults from Mexico, Greenland, China and Denmark. Both age groups provided higher centrality ratings to the positive life event; however, the relative difference between the ratings for the positive and negative event was smaller in the young adults. Young adults reported significantly more distress and less well-being across cultures.     

父母教养与MAOA基因rs6323多态性对学前儿童外化问题的共同作用

采用G×E交互作用的研究范式,以295名学前儿童（M=4.49）和其母亲、父亲作为研究对象,探讨母亲和父亲的教养方式与MAOA基因rs6323多态性对学前儿童外化问题行为的影响。结果发现：母亲、父亲教养方式和MAOA基因多态性对学前儿童外化问题行为的影响存在性别差异,预测男孩外化问题行为时,母亲和父亲教养方式的主效应显著,与MAOA基因多态性的交互作用不显著;在预测女孩外化问题行为时,父亲教养方式的主效应显著,母亲教养方式与MAOA基因多态性的交互作用显著,显著性区域分析发现,携带T等位基因的女孩更容易受到母亲消极教养的不利影响而产生更多外化问题行为,也更容易受到其积极教养的有利影响而减少外化问题行为,这一结果支持差别易感性理论模型。     

Effects of domain knowledge,working memory capacity,and age on cognitive performance: an investigation of the knowledge-is-power hypothesis

Domain knowledge facilitates performance in many cognitive tasks. However, very little is known about the interplay between domain knowledge and factors that are believed to reflect general, and relatively stable, characteristics of the individual. The primary goal of this study was to investigate the interplay between domain knowledge and one such factor: working memory capacity. Adults from wide ranges of working memory capacity, age, and knowledge about the game of baseball listened to, and then answered questions about, simulated radio broadcasts of baseball games. There was a strong facilitative effect of preexisting knowledge of baseball on memory performance, particularly for information judged to be directly relevant to the baseball games. However, there was a positive effect of working memory capacity on memory performance as well, and there was no indication that domain knowledge attenuated this effect. That is, working memory capacity contributed to memory performance even at high levels of domain knowledge. Similarly, there was no evidence that domain knowledge attenuated age-related differences (favoring young adults) in memory performance. We discuss implications of the results for understanding proficiency in cognitive domains from an individual-differences perspective.     

The human first hypothesis: identification of conspecifics and individuation of objects in the young infant

How do infants individuate and track objects, and among them objects belonging to their species, when they can only rely on information about the properties of those objects? We propose the Human First Hypothesis (HFH), which posits that infants possess information about their conspecifics and use it to identify and count objects. F. Xu and S. Carey [Cognitive Psychology, 30(2), 111-153, 1996] argued that before the age of 1 year, infants fail to use property information. To explain their results, Xu and Carey proposed the Object First Hypothesis (OFH), according to which infants under 1 year of age have only the general concept of physical object to identify and count objects. We show that infants have a more extensive knowledge of sortals than that claimed by the OFH. When 10-month-olds see one humanlike and one non-humanlike object, they successfully identify and count them by using the contrast in their properties, as predicted by the HFH. We also show that infants succeed even when they make a decision based on differences between two close basic-level categories such as humanlike objects and doglike objects, but fail when they have to use differences within the human category. Thus, infants treat "human" as a basic sortal, as predicted by the HFH. We argue that our results cannot be accounted for by general purpose mechanisms. Neither the strong version of the OFH and its explanation in terms of object indexing mechanisms [A. M. Leslie, F. Xu, P. Tremoulet, & B. J. Scholl, Trends in Cognitive Sciences, 2(1), 10-18, 1998] nor explanations in terms of task demands [T. Wilcox & R. Baillargeon, Cognitive Psychology, 37(2), 97-155, 1998] are sufficient to explain our results.     

The role of collaborative planning in children's source-monitoring errors and learning.

The aim of this research was to provide empirical evidence for a cognitive process that may contribute to children's learning from another person. A cornerstone of Vygotsky's sociocultural theory is that knowledge is internalized from others; however, the cognitive processes that support this transformation are underspecified. In a series of three studies, kindergarten children (mean age 5 years 8 months) participated in a categorization task with an adult in several collaborative and noncollaborative conditions and then were tested on their memory of who had performed which actions in the task. After the memory task, children were asked to recategorize the items on their own. Source-monitoring patterns and children's learning varied across conditions according to predictions. A measure of recoding was related to children's planning language that, in turn, predicted learning among the children. The results suggest that one process that contributes to children's internalization of knowledge may involve recoding of agent information and that recoding can be indexed by source-monitoring performance.     

Measuring aggression: Self‐reports,partner reports,and responses to provoking scenarios

This paper describes three studies. The first is concerned with the relationship between the Aggression Questionnaire (AQ) and a peer‐report version of the AQ (AQ‐P). The results (from a sample of 77 men aged 19 to 55 years) showed agreement between the two versions, thus providing evidence for the congruent validity of the AQ‐P, and good internal consistency was shown for the subscales of the AQ and AQ‐P. The second study involved the development, piloting, and validation of a vignette‐based assessment of aggressive behavior, the Aggressive Provocation Questionnaire. The third concerned the use of the finalised Aggressive Provocation Questionnaire in a sample of 130 men (aged 17 to 54 years). The results show that prior self‐reported aggression (measured by the AQ) predicted responses to provoking scenarios. Younger men (< 28 years) showed an association between physical aggression and the aggressive action scale (of the Aggressive Provocation Questionnaire) in response to provoking scenarios. Older men (> 28 years) showed an association between physical aggression and the assertive action scale. The findings are discussed in relation to aggression measurement and changes in aggression with age. Aggr. Behav. 27:79–101, 2001. © 2001 Wiley‐Liss, Inc.     

La distribution du voisinage influence l'amorçage orthographique non masqué des mots écrits

The aim of the present research is to study whether orthographic neighbourhood distribution influences unmasked orthographic priming. Two word conditions were compared in the lexical decision task. All word targets had two higher frequency neighbours that were either spread across two letter positions (SINGE/linge-songe) or concentrated on a single letter position (RUCHE/riche-roche). Results showed an inhibitory effect of unmasked orthographic priming. Furthermore, this priming effect was influenced by the target neighbourhood distribution. Priming was only found when the word targets had two neighbours that were spread across two letter positions. These data are discussed within an interactive activation framework in terms of prime activation (Versace and Nevers, 2003).
