Functional Magnetic Resonance Imaging
3 studies
Functional Magnetic Resonance Imaging (fMRI) is a non-invasive neuroimaging technique that measures brain activity by tracking changes in blood flow and blood oxygenation levels. Because active brain areas consume more oxygen and require more blood, fMRI allows researchers to map which specific regions of the brain are engaged during different tasks. This technique provides a safe way to observe the human brain in action without the need for surgery or radioactive materials.
fMRI is crucial for psychology because it helps bridge the gap between mental processes and biological brain activity. It allows psychologists to test whether different cognitive functions, such as language processing or emotional regulation, rely on shared or distinct neural systems. Furthermore, fMRI can reveal hidden neural processes that participants may not be able to consciously report on behavioral surveys.

What we know
- fMRI can reveal significant differences in brain activation patterns during social experiences, such as social exclusion, even when participants' behavioral self-reports show no differences.
- Functional neuroimaging demonstrates that signed and spoken languages share a common core linguistic network in the brain, despite relying on different modality-specific regions for sensory-motor execution.
- Resting-state fMRI can identify changes in the functional connectivity of attention networks after long-term physical interventions, though these brain network changes may not directly correlate with behavioral improvements.
Common misconceptions
If an intervention improves a psychological behavior and also changes functional connectivity in the brain, the neural change is the direct cause of the behavioral improvement.
Parallel changes in brain networks and behavior do not automatically mean they are directly related; statistical analyses sometimes reveal no direct correlation between the observed brain changes and the cognitive improvements.
If behavioral self-report ratings show no differences between two conditions, it means the brain is processing those situations in an identical manner.
fMRI scans can detect profound differences in neural activation and deactivation (such as in the orbitofrontal cortex and hippocampus) even when conscious behavioral ratings of an experience remain unchanged.
Because sign language is visual and spoken language is auditory, they are processed in completely separate, non-overlapping language systems in the brain.
While sign and spoken languages recruit different sensory and motor regions to handle physical production and perception, they share a core bilateral network for underlying linguistic processing.

- Does Mind-Body Exercise Help Attention in Older Adults?
Baduanjin mind-body exercise improved selective attention in older adults with mild cognitive impairment, but this improvement was not clearly linked to changes in brain network connections.
- How does using hands vs speech change brain activity for language?
While both sign and spoken languages share a core language network in the brain, they recruit different sensory-motor regions to support hand movements versus vocal articulation and hearing.
- Does smelling anxiety change how we feel when left out?
Smelling another person's sweat collected during an anxious situation reduces brain activity in areas typically associated with social pain and mentalizing when a person is being excluded from a social game.

Discuss how fMRI can reveal cognitive processing differences that are invisible to traditional behavioral self-report measures, drawing on research involving social exclusion.
fMRI can capture objective neural changes that behavioral scales miss. In a study using the Cyberball task, participants reported feeling equally excluded on behavioral measures regardless of the scent they smelled. However, fMRI data revealed that smelling anxiety-related sweat prevented the typical activation of social pain centers (the orbitofrontal cortex and anterior cingulate) and deactivated memory and temporal areas. This shows that the brain processed the exclusion differently based on sensory context, even though the participants' conscious ratings of the experience remained identical.
Why must researchers exercise caution when concluding that a change in brain network connectivity (measured by fMRI) explains a behavioral improvement following an intervention?
Researchers must be cautious because co-occurring changes in the brain and behavior do not prove a direct relationship. For example, after a 24-week exercise intervention, participants showed both improved selective attention and decreased connectivity in the dorsal attention network. However, there was no statistical correlation between the brain connectivity changes and the behavioral attention gains. This demonstrates that neural and behavioral changes can occur independently or through complex, indirect pathways that fMRI alone cannot establish as directly causal.
Explain how functional neuroimaging studies support the idea that the brain processes language using both modality-specific and core language systems.
Functional imaging (fMRI and PET) comparing sign language and spoken language demonstrates that the brain adapts to physical demands while maintaining a core system. For modality-specific demands, sign language recruits motor areas for upper-limb control and visual processing areas, whereas spoken language recruits motor areas for mouth control and auditory areas in the temporal lobe. Crucially, however, both languages share a core bilateral linguistic network, demonstrating that the brain routes different physical modalities into a unified language processing system.
