Individual differences in the speed of information processing have been hypothesized to give rise to individual differences in general intelligence. Consistent with this hypothesis, reaction times (RTs) and latencies of event-related potential have been shown to be moderately associated with intelligence. These associations have been explained either in terms of individual differences in some brain-wide property such as myelination, the speed of neural oscillations, or white-matter tract…

How robust is the relationship between neural processing speed and cognitive abilities?

Individual differences in processing speed are consistently related to individual differences in cognitive abilities, but the mechanisms through which a higher processing speed facilitates reasoning

Disentangling the Effects of Processing Speed on the Association between Age Differences and Fluid Intelligence

TLDR
This study investigated whether individual differences in diffusion model parameters and in ERP latencies associated with higher-order attentional processing explained the association between age differences and fluid intelligence, and suggested that the relationship between age Differences and fluid Intelligence is multifactorially determined.

A chronometric model of the relationship between frontal midline theta functional connectivity and human intelligence.

TLDR
The results suggest that more intelligent individuals benefit from an adaptive modulation of theta-band synchronization during the time-course of information processing, which supports theoretical accounts of intelligence and emphasizes the role of interregional goal-directed information-processing for cognitive control processes in human intelligence.

Individual Differences in Cortical Processing Speed Predict Cognitive Abilities: a Model-Based Cognitive Neuroscience Account

TLDR
This work used a hierarchical Bayesian cognitive modeling approach and found that a higher neural speed predicted both the velocity of evidence accumulation across behavioral tasks and cognitive ability test scores, suggesting that speeded neural information processing may facilitate evidence accumulation during decision making and memory updating and thus yield advantages in general cognitive abilities.

Intelligence and Visual Mismatch Negativity: Is Pre-Attentive Visual Discrimination Related to General Cognitive Ability?

TLDR
This study presents the first test of whether neural indices of pre-attentive visual discrimination processes are related to intelligence and discusses critical differences between the auditory and visual MMN and recommendations for further research in this evolving field.

An Investigation of the Slope Parameters of Reaction Times and P3 Latencies in the Sternberg Memory Scanning Task – A Fixed-Links Model Approach

TLDR
The FLM proved suitable to investigate the association between the speed of short-term memory scanning and intelligence and found no evidence for a linear increase, but a general increase from the smallest set size to the two larger ones.

The latency of a visual evoked potential tracks the onset of decision making

TLDR
Evidence is reported that visual evoked potentials (EPs) around 200 ms after stimulus presentation track the time of visual figure-ground segregation before the onset of evidence accumulation during decision making, adding to the growing literature that suggests that EEG signals can track the component cognitive processes of decision making.

Do Non-Decision Times Mediate the Association between Age and Intelligence across Different Content and Process Domains?

TLDR
Estimated mediation models investigated whether age differences in diffusion model parameters account for the negative relation between age and intelligence, across different intelligence process domains (processing capacity, memory, psychometric speed) and different intelligence content domains (figural, numeric, verbal).

Previous research has shown an inverse relation between response times in elementary cognitive tasks and intelligence, but findings are inconsistent as to which is the most informative score. We

Retest reliability of event-related potentials: evidence from a variety of paradigms.

TLDR
It is confirmed that a range of prominent ERPs provide highly stable neurophysiological indices of human cognitive function and peak latency reliability varied substantially across components and ranged from weak to strong.

TLDR
The authors assess the construct space for WM and g and demonstrate that WM shares substantial variance with perceptual speed (PS) constructs and construct overlap between PS and WM is investigated.

General intelligence and memory span: Evidence for a common neuroanatomic framework

TLDR
Results indicate that a common anatomic framework for these constructs implicates mainly frontal grey matter regions belonging to Brodmann area (BA) 10 and left middle frontal gyrus and, to a lesser degree, the right inferior parietal lobule (BA 40).
