Examination marking utilises a variety of cognitive processes, and from a psychological perspective, the demands that different questions place on markers will vary considerably. To what extent does marking accuracy vary among markers with differing backgrounds and experiences? More fundamentally, what makes some questions harder to mark…

Concept maps consist of nodes that represent concepts and links that represent relationships between concepts. Various studies have shown that concept mapping fosters meaningful learning. However, little is known about the specific cognitive processes that are responsible for such mapping effects. In a thinking-aloud study, we analyzed the…

This study investigates the ability of 6-month-old infants to attend to the continuous properties of a set of discrete entities. Infants were habituated to dot arrays that were constant in cumulative surface area yet varied in number for small (less than 4) or large (greater than 3) sets. Results revealed that infants detected a 4-fold (but not…

Design, including instructional design, is one of most complex and ill-structured kinds of problem solving. Historically, instructional design has been conceptualized as a linear set of phases (e.g., analysis, design, development, implementation, evaluation) that a designer progresses through. Silber (2007) has provided an alternative perspective…

Evolutionary psychologists have proposed that humans possess cognitive mechanisms for social exchange, but have perhaps focused overmuch on "cheating", because avoiding exploitation in reciprocal exchange could be accomplished either by avoidance of defectors or by attraction to cooperators. Past studies that have claimed to support the existence…

Using the theory of mental models to account for the process of human mental information processing and representation has become an important approach in the field of knowledge engineering. Most methods of knowledge assessment are based on graphical concept mapping techniques. Tools like MITOCAR complement the graphical approaches by…

This paper proposes to discuss the concept of multimedia using information processing theory in ICT enabled teacher education in the context of a knowledge society. The Information and communication technology (ICT) competencies required of teachers related to content, pedagogy, technical issues, social issues, collaboration and networking remain…

Recent research has shown that adults can implicitly learn artificial phonotactics constraints from experience producing syllables that contain those constraints, and that this learning is reflected in their speech errors. However, second-order constraints in which the placement of a consonant depends on another characteristic of the syllable…

When we hear a word, it is remarkable how we store, activate and rapidly retrieve a vast amount of relevant information within a few hundred milliseconds. This thesis examines how meaning is processed in parallel--but with critical differences--between the two hemispheres of the brain. Event-related brain potentials (ERP) were used to examine…

Set shifting provokes specific alterations of cerebral hemodynamics in basal cerebral arteries. However, no gender differences have been reported. In the following functional transcranial Doppler study, we introduced cerebral hemodynamic modulation to the aspects of set shifting during Wisconsin Card Sorting Test (WCST). Twenty-one subjects…

This paper presents the strategies employed by Indian middle-school students working in groups to identify three unfamiliar artefacts. The activity described in this paper was aimed at sensitising students to the close link between form and function and to bring a certain amount of uncertainty in the tasks before the actual design task. It was…

The remote associates test (RAT) is a complex verbal task with associations to both creative thought and general intelligence. RAT problems require not only lateral associations and the internal production of many words but a convergent focus on a single answer. Complex problem-solving of this sort may thus require both substantial verbal…

As literate adults, we appreciate numerical values as abstract entities that can be represented by a numeral, a word, a number of lines on a scorecard, or a sequence of chimes from a clock. This abstract, notation-independent appreciation of numbers develops gradually over the first several years of life. Here, using functional magnetic resonance…

Behavioral studies show that infants are capable of discriminating the number of objects or events in their environment, while also suggesting that number discrimination in infancy may be ratio-dependent. However, due to limitations of the dependent measures used with infant behavioral studies, the evidence for ratio dependence falls short of the…

This article describes how to use clay as a potential material for young children to explore. As teachers, the authors find that their dialogue about the potential of clay as a learning medium raises many questions: (1) What makes clay so enticing? (2) Why are teachers noticing different play and conversation around the clay table as compared to…
