Identifying the precise locus of general cognitive ability (g) in the flow of information between perception and action is an important goal of differential psychology. To localize the negative correlation between g and reaction time to a specific processing stage, we administered a speeded number-comparison task to two groups differing in average g. The participants had to respond to two stimuli in each trial, which produced the well-known slowing of the second reaction time known as the…

The working memory costs of a central attentional bottleneck in multitasking

It is concluded that the existence of serial processing in multitasking demands additional control processes (active scheduling) and that these processes are strongly linked to the executive functions of working memory.

Analyzing Reaction Time and Error Sequences in Lexical Decision Experiments

It is shown that a recently introduced graph based RT analysis method can help to better understand and analyze RT sequences and extend previous research on methods for discovering and removing so-called local speed effects from RT sequences.

The Playing Field : Findings for Evaluating Hypotheses About WM Capacity

We review the evidence for the 3 principal theoretical contenders that vie to explain why and how working memory (WM) capacity is limited. We examine the possibility that capacity limitations arise

What limits working memory capacity?

The interference approach has its own set of difficulties but accounts best for the set of findings, and therefore, appears to present the most promising approach for future development.

Comparing reaction time sequences from human participants and computational models

This paper proposes a method, based on time series analysis, to filter the observed reaction times in order to separate the local speed effects, and shows that after such filtering the between-participant correlations increase as well as the average correlation between participant and model increases.

Digital neuropsychology: Challenges and opportunities at the intersection of science and software

Digital neuropsychology provides new approaches for measuring and monitoring neuropsychological functioning, informed by an understanding of the limitations and potential of digital technology.

Combining Data-Oriented and Process-Oriented Approaches to Modeling Reaction Time Data

This paper combines two different approaches to modeling reaction time data from lexical decision experiments, viz. a dataoriented statistical analysis by means of a linear mixed effects model, and a

Two Separate, Large Cohorts Reveal Modifiers of Age-Related Change in Visual Reaction Time Performance

An analysis of RT and svTR data from the MindCrowd cohort revealed education and reported stroke as potential modifiers of age-associated processing speed and memory decline and suggested that education and smoking status were related to opposite effects on age-related svRT slowing.



The Relationship between Attentional Blink and Psychological Refractory Period

This study examined the relationship between attentional blink (AB) and psychological refractory period (PRP) using a conventional AB procedure combined with a requirement of speeded responses to the

Brain Mechanisms of Serial and Parallel Processing during Dual-Task Performance

The psychological refractory period (PRP) refers to the fact that humans typically cannot perform two tasks at once. Behavioral experiments have led to the proposal that, in fact, peripheral

Parsing a Cognitive Task: A Characterization of the Mind's Bottleneck

A number-comparison task provided a thorough test of the model by allowing independent variations in number notation, numerical distance, response complexity, and temporal asynchrony relative to an interfering probe task of tone discrimination and revealed a parsing of the comparison task in which each variable affects only one stage.

Functional Magnetic Resonance Imaging Provides New Constraints on Theories of the Psychological Refractory Period

fMRI data suggest that passive queuing, rather than active monitoring, occurs during the psychological refractory period, and in brain regions postulated to be important for executive functions, there was virtually no increase in brain activation in the short-interval compared with the long-intervals condition.

Chronometric Evidence for Central Postponement in Temporally Overlapping Tasks

When the stimuli from two tasks arrive in rapid succession (the overlapping tasks paradigm), response delays are typically observed. Two general types of models have been proposed to account for

Limits on Introspection

It is demonstrated that introspective response time can be a sensitive measure, tightly correlated with objective response time in a single-task context, but in a psychological-refractory-period task, the objective processing delay resulting from interference by a second concurrent task is totally absent from introspective estimates.

The authors bring together approaches from cognitive and individual differences psychology to model characteristics of reaction time distributions beyond measures of central tendency. Ex-Gaussian

How the simultaneous recording of event-related potentials (ERPs) in the same task can provide complementary information that cannot be obtained using RTs alone is described.

Dynamics of the Central Bottleneck: Dual-Task and Task Uncertainty

A hierarchical model of cognitive architecture is proposed that provides a synthesis of task-switching and PRP paradigms and clarifies the chronometric relations between these central components of dual-task processing, and in particular whether they operate serially or in parallel.
