In this chapter, we discuss the measurement of working memory capacity and attention control. We begin by examining the origins of complex span measures of working memory capacity, which were created to better understand the cognitive processes underpinning language comprehension. We then review evidence for the executive attention theory of workin...

Extant literature suggests that performance on visual arrays tasks reflects limited-capacity storage of visual information. However, there is also evidence to suggest that visual arrays task performance reflects individual differences in controlled processing. The purpose of this study is to empirically evaluate the degree to which visual arrays ta...

Cognitive tasks that produce reliable and robust effects at the group level often fail to yield reliable and valid individual differences. An ongoing debate among attention researchers is whether conflict resolution mechanisms are task-specific or domain-general, and the lack of correlation between most attention measures seems to favor the view th...

We evaluated the predictive value of the Armed Services Vocational Aptitude Battery (ASVAB) at the latent level, using multitasking as a proxy for real-world job performance. We also examined whether adding measures of attention control to the ASVAB could improve its predictive validity. To answer these questions, data were collected from 171 young...

Intelligence is correlated with the ability to make fine sensory discriminations. Although this relationship has been known since the beginning of intelligence testing, the mechanisms underlying this relationship are still unknown. In two large-scale structural equation-modelling studies, we investigated whether individual differences in attention...

**The uploaded manuscript is still in preparation** In this study, we tested the relationship between visual arrays tasks and working memory capacity and attention control. Specifically, we tested whether task design (selection or non-selection demands) impacted the relationship between visual arrays measures and constructs of working memory capaci...

This study uses a novel framework based on work by Shipstead, Harrison, and Engle (2016) that includes measures of both working memory capacity and fluid intelligence in an attempt to better understand the processes that influence successful reading comprehension at the latent level. Further, we extend this framework to a second educationally relev...

Reaction time is believed to be a good indicator of the speed and efficiency of mental processes and is a ubiquitous variable in the behavioral sciences. Despite this popularity, there are numerous issues associated with using reaction time (RT), specifically in differential and developmental research. Here, we identify and focus on two main proble...

Visuospatial working memory (VSWM) task are often treated as if they strictly measure the storage capacity of a domain-specific system. The present study examined (1) The degree to which these tasks actually tap into domain-general processes (2) The role attention plays in task performance. Study 117 students from Arizona State University. 3 tests...

The present study examined the degree to which tests of visuospatial storage capacity tap into domain-general storage and attention processes. This was done by comparing performance of visuospatial memory tasks with performance on sound-based sensory discrimination tasks. We found that memory task- and discrimination task performance both tapped in...

Examination of the role of maintenance and disengagement processes as explanations of the relation of Gf to reading comprehension.

Millions of children across the world are exposed to multiple sources of indoor and outdoor air pollutants, including high concentrations of fine particulate matter (PM2.5) and ozone (O3). The established link between exposure to PM2.5, brain structural, volumetric and metabolic changes, severe cognitive deficits (1.5-2 SD from average IQ) in APOE...
