The objective of this study was to redesign the Tower of Hanoi (TOH) in order to increase the reliability and explore the validity of the task. In order to achieve this goal, a two-phase process was undertaken. In Phase 1, the TOH item pool was enlarged from 12 items to 60 items, and the task was administered to a sample of college students (N = 81). The 22 most homogeneous items for the final ...

This is the main entry point for the scheduler. This method has to be overridden to implement the scheduling algorithm. It is called from the JVM on a timed event or a software interrupt (see genInt()) is issued (e.g. when a Task gives up execution). vo i d i n t e r r u p t ( i n t nr ) The scheduler is notified on a hardware event. It can directly call an associated device driver or use this ...

The Simon effect refers to the performance (response time and accuracy) advantage for responses that spatially correspond to the task-irrelevant location of a stimulus. It has been attributed to a natural tendency to respond toward the source of stimulation. When location is task-relevant, however, and responses are intentionally directed away (incompatible) or toward (compatible) the source of...

In this paper we present a cognitive-modeling analysis of processes of volitional action control in multiple-task performance. We simulated experimentally obtained effects of goal competition and task difficulty on processing strategies and performance in a high-level learning and problem-solving task within the ACT-R architecture (version 4.0). Beyond the model's capacity for explaining the em...

This paper presents a cognitive model of a subliminal priming task, using Retrieval by ACcumulating Evidence (RACE), a model of declarative memory retrieval. RACE is implemented as an extension to the ACT-R architecture of cognition. First, we will discuss the exact implementation of RACE within the constraints imposed by ACT-R. Second, we will discuss the subliminal priming task that we modele...

There has been little empirical evidence examining the overlap in nomothetic span for self-report measures and construct representation for behavioral lab tasks in most psychological constructs. Using the personality trait of impulsivity as an example, the authors completed a meta-analysis of 27 published research studies examining the relationship between these methods. In general, although th...

Language is lateralised to the left hemisphere in most people, but it is unclear whether the same degree and direction of lateralisation is found for all verbal tasks and whether laterality is affected by task difficulty. We used functional transcranial Doppler ultrasonography (fTCD) to assess the lateralisation of language processing in 27 young adults using three tasks: word generation (WG), ...

The problem of indexing multidimensional objects is considered. First, a classification of existing methods is given along with a discussion of the major issues involved in multidimensional data indexing. Second, a variation to Guttman’s R-trees (R+-trees) that avoids overlapping rectangles in intermediate nodes of the tree is introduced. Algorithms for searching, updating, initial packing and ...
