Objective: To evaluate support for three hypotheses about the etiology of adolescent-onset ADHD symptoms: (1) a "cool" cognitive load hypothesis, (2) a "hot" rewards processing hypothesis, and (3) a trauma exposure hypothesis. Method: Participants (N=50) were drawn from two public high schools in a culturally diverse…

The purpose of this study was to challenge autonomous views of writing and deficit views of students who struggle with school literacy. This study is an exploration of students' use of social, linguistic, and cognitive resources to construct meaning in narrative writing events in school. The following research questions guided this inquiry: What…

The nature of knowledge in vocational education is often described in dichotomies such as theory versus practice or general versus specific. Although different scholars now acknowledge that vocational knowledge is more than putting bits of theoretical and practical knowledge together, it is still unclear how vocational knowledge should be…

Memory retrieval often enhances still later memory as evidenced by the testing effect. Divided attention (DA) is known to produce different effects on encoding and retrieval, substantially disrupting the former and often producing little effect on the latter. The present experiments examine whether the mnemonic consequences of retrieval are…

Several approaches to implementing symbol-like representations in neurally plausible models have been proposed. These approaches include binding through synchrony (Shastri & Ajjanagadde, 1993), "mesh" binding (van der Velde & de Kamps, 2006), and conjunctive binding (Smolensky, 1990). Recent theoretical work has suggested that…

Auditory stream segregation allows us to organize our sound environment, by focusing on specific information and ignoring what is unimportant. One previous study reported difficulty in stream segregation ability in children with Asperger syndrome. In order to investigate this question further, we used an interleaved melody recognition task with…

To understand language, humans must encode information from rapid, sequential streams of syllables--tracking their order and organizing them into words, phrases, and sentences. We used Near-Infrared Spectroscopy (NIRS) to determine whether human neonates are born with the capacity to track the positions of syllables in multisyllabic sequences.…

Can Levinas' thought of the other be extended beyond the relation to the other human being? This article seeks to demonstrate that Levinas' philosophy can indeed be read in such a sense and that this serves to open up a new way of understanding human thinking. Key to understanding such an extension of Levinas' philosophy will be his account of the…

There is much evidence that the prospect of reward modulates cognitive control in terms of more stable behavior. Increases in expected reward magnitude, however, have been suggested to increase flexible behavior as evidenced by reduced switch costs. In a series of experiments, the authors provide evidence that this increased cognitive flexibility…

Our mental maps related to the cities are limited by our personal perception and fragmented in the process. There are many inner and outer effects that shape our mental maps, and as a result the fragmented whole refers to the total city image in our minds. To represent this image, an experimental study has been conducted with a group of students.…

Reasoning and inference are well-studied aspects of basic cognition that have been explained as statistically optimal Bayesian inference. Using a simplified experimental design, we conducted quantitative comparisons between Bayesian inference and human inference at the level of individuals. In 3 experiments, with more than 13,000 participants, we…

The aim of the research is to determine the peculiarities of the evaluative categorization of human intelligence in linguistic world images. The study describes the interdisciplinary approach to studying evaluative categorization, which assumes the use of complex methodology including the anthropocentric, the interdisciplinary, and the cognitive…

This paper presents a contribution to the development of a theory of CSCL scripts, i.e., an understanding of what happens when learners engage in such scripts. It builds on the Script Theory of Guidance (SToG) recently proposed by (Fischer et al. in "Educational Psychologist," 48(1), 56-66, 2013). We argue that, when engaged in a…

Integrative encoding and generalization across past experiences depends largely on the hippocampus, an area known to be particularly sensitive to stress. Yet, whether stress influences the ability to generalize memories is unknown. We exposed volunteers to a stressor or a control manipulation before they completed an acquired equivalence task…

Music plays an important part in the transitional period of life for adolescents as they define their personal and social identities and build their preferences for music. Recent neuroscientific research into the adolescent brain has produced developmental models that work to explain the neural reasons behind teenage behavior and development.…
