Summary

In the current chapter, we review the research on close relationships done via the methodologies of neuroscience – in short relationship neuroscience (RN). Much of the research we review focuses on attachment (child–parent or romantic) and sexuality. Nevertheless, we aim to cover RN broadly defined. We start by framing our topic and providing a few working definitions. We then cover the various relational (attachment, interdependence) and neuroscience (social baseline theory, and the Functional Neuroanatomical Model of Human Attachment) theories, methodologies (MRI, ERPs, and genetics), and types of relationships (familial relations, romantic, friendships, sexual relations, etc.) used or covered in this subfield. We explore both positive and negative aspects of close relationships. Finally, we reflect on the bidirectional link and contributions between relationship science and neuroscience and suggest potential implications for mental and physical health and policymaking. We also outline some remaining issues and future directions for RN.

Accessibility standard: Inaccessible, or known limited accessibility

Why this information is here

This section outlines the accessibility features of this content - including support for screen readers, full keyboard navigation and high-contrast display options. This may not be relevant for you.

Accessibility Information

The HTML of this chapter is known to have missing or limited accessibility features. We may be reviewing its accessibility for future improvement, but final compliance is not yet assured and may be subject to legal exceptions. If you have any questions, please contact accessibility@cambridge.org.

Content Navigation

Table of contents navigation
Allows you to navigate directly to chapters, sections, or non‐text items through a linked table of contents, reducing the need for extensive scrolling.
Index navigation
Provides an interactive index, letting you go straight to where a term or subject appears in the text without manual searching.

Reading Order & Textual Equivalents

Single logical reading order
You will encounter all content (including footnotes, captions, etc.) in a clear, sequential flow, making it easier to follow with assistive tools like screen readers.
Full alternative textual descriptions
You get more than just short alt text: you have comprehensive text equivalents, transcripts, captions, or audio descriptions for substantial non‐text content, which is especially helpful for complex visuals or multimedia.
Visualised data also available as non-graphical data
You can access graphs or charts in a text or tabular format, so you are not excluded if you cannot process visual displays.

Visual Accessibility

Use of colour is not sole means of conveying information
You will still understand key ideas or prompts without relying solely on colour, which is especially helpful if you have colour vision deficiencies.
Use of high contrast between text and background colour
You benefit from high‐contrast text, which improves legibility if you have low vision or if you are reading in less‐than‐ideal lighting conditions.
