Children learn the words for above–below relations earlier than for left–right relations, despite treating these equally well in a simple visual categorization task. Even as adults—conflicts in congruency, such as when a stimulus is depicted in a spatially incongruent manner with respect to salient global cues—can be challenging. Here we investigated the neural correlates of encoding and maintaining in working memory above–below and left–right relational planes in 12 adults using…

Language unifies relational coding: The roles of label acquisition and accessibility in making flexible relational judgments.
TLDR
It is found that the verbal ability to make above/below judgments preceded verbal right/left judgments and all nonverbal judgments and that only when the labels were accessed did children's nonverbal performance improve.

The Neural Basis for Spatial Relations
TLDR
The findings suggest that the functional neuroanatomy of categorical and coordinate processing is more nuanced than implied by a simple hemispheric dichotomy.
Focusing Narrowly or Broadly Attention When Judging Categorical and Coordinate Spatial Relations: A MEG Study
TLDR
The present results support the theory that the lateralization of each kind of spatial processing hinges on differences in the sizes of regions of space attended to by the two hemispheres and contradict the idea of a right-hemispheric dominance for all kinds of challenging spatial tasks.
Neural systems that encode categorical versus coordinate spatial relations: PET investigations
Participants received three sets of trials while regional cerebral blood flow was assessed using positron emission tomography (PET). In one set, the baseline, they responded when they detected a
Rostrolateral prefrontal cortex: Domain‐general or domain‐sensitive?
TLDR
Analysis of fMRI activation and functional connectivity during performance of visuospatial and semantic variants of a relational matching task found that RLPFC is well‐positioned as a locus of abstraction from concrete, domain‐specific details to the general principles and rules that enable higher‐level cognition.
Categorical and coordinate spatial relations: fMRI evidence for hemispheric specialization.
TLDR
Functional magnetic resonance imaging was applied to determine the involvement of the angular gyri in the processing of categorical and coordinate spatial relations, and stronger activation of the left than of the right angular gyrus in the categorical task.
A hierarchy for relational reasoning in the prefrontal cortex
TLDR
Findings indicate that stages of neural processing overlap for different domains within human reasoning, and suggests a hierarchical organization for relational reasoning across domains in which posterior frontal cortex is active across concrete reasoning tasks, while progressively more anterior regions are recruited to process increasingly abstract representations in reasoning.
Neural Correlates of Naming Actions and of Naming Spatial Relations
TLDR
The objective was to test the following hypothesis: that the salient neural activity associated with naming actions and spatial relations occurs in left frontal operculum and left parietal association cortices, but not in the left inferotemporal cortices (IT) or in the right parietal Association cortices.
Representing spatial relationships in posterior parietal cortex: single neurons code object-referenced position.
TLDR
Recorded neural activity in parietal area 7a of monkeys performing an object construction task found that neurons were activated as a function of the spatial relationship between a task-critical coordinate and a reference object.
Neural Correlates of Fluid Reasoning in Children and Adults
TLDR
Age- related changes in the recruitment of VLPFC, temporal cortex, and other cortical regions were observed during the retrieval of individual semantic relations, and age-related changes in RLPFC function were observed when relational integration was observed.
Reasoning and working memory: common and distinct neuronal processes
TLDR
The notion that relational reasoning is based on visuo-spatial mental models is supported, and fMRI results help to distinguish the neuronal processes related to reasoning itself versus to the maintenance of problem information in working memory.
