Brain morphology and cognitive ability change with age. Gray and white matter volumes decrease markedly by the 7th decade of life when cognitive decreases first become readily detectable. As a consequence, the shape complexity of the cortical mantle may also change. The purposes of this study are to examine changes over a five year period in brain structural complexity in late life, and to inve...

This paper proposes a model for calculating cognitive complexity of a code. This model considers all major factors responsible for (cognitive) complexity. The practical applicability of the measure is evaluated through experimentation, test cases and comparative study.

The nonlinear properties of spontaneous fluctuations in blood oxygen level-dependent (BOLD) signals remain unexplored. We test the hypothesis that complexity of BOLD activity is reduced with aging and is correlated with cognitive performance in the elderly. A total of 99 normal older and 56 younger male subjects were included. Cognitive function was assessed using Cognitive Abilities Screening ...

Functional complexity is one of the most fundamental properties of software because almost all other software attributes and properties such as functional size, development effort, costs, quality, and project duration are highly dependent on it. The functional complexity of software is a macro-scope problem concerning the semantic properties of software and human cognitive complexity towards a ...

Many computationalor rational-level models of cognition postulate computations that appear to be computationally intractable (e.g., NP-hard or worse). Formally, this means that the postulated computations consume an exponential amount of time. Informally, this means that the postulated computations do not scale in any obvious way to explain how the modeled cognitive capacities can operate in th...

BACKGROUND Self-administered depression measures are important tools for research and practice, but their utility depends on the quality of the measurements they yield. Respondent comprehension is essential for meaningful measurement and prior studies have used readability indices to assess comprehensibility. Readability, however, is only one aspect of comprehension and empirical evidence shows...

Method hiding plays a key role by serving the foundation for several guidelines in object-oriented software design. It brings about plethora of benefits such as easy comprehension, secured accessibility, modifiability without side-effects, modular testing, higher reliability etc. But, it has to be handled carefully since very low method hiding may result in insufficiently abstracted implementat...

Relational complexity (RC) is a metric reflecting capacity limitation in relational processing. It plays a crucial role in higher cognitive processes and is an endophenotype for several disorders. However, the genetic underpinnings of complex relational processing have not been investigated. Using the classical twin model, we estimated the heritability of RC and genetic overlap with intelligenc...

INTRODUCTION During information presentation, the target audience must construct a mental representation of situations or scenarios conveyed by the verbal content and images contained in the presentation. Cognitive psychologists refer to these representations as situation models (Friedman & Miyake, 2000). During situation model construction , increases in the number of alternative order of even...
