Deconstructing the most sensationalistic recent findings in Human Brain Imaging, Cognitive Neuroscience, and Psychopharmacology. Can brain activity measured while rating potential dates predict later choices at speed dating events? Haven't you lay awake at night wondering if 36 voxels in your rostromedial prefrontal cortex RMPFC can predict your future romantic decisions?
If you have, you're in luck. Cooper and colleagues conducted an fMRI study to answer this burning question in the affirmative. This might be hard for me, but I'll try to seriously convey the major point of the study: My immediate retort to the experimental approach is why would you ever think that
Journal speed dating voxels in one brain area and 34 in another can drive such a complicated decision?? Love dating sim 2 jenna
But that was the finding of this paper, which was published in the Journal of Neuroscience. To describe the methods in brief,
Journal speed dating single young heterosexual adults participated in a scanning session where they viewed photographs of their potential dates and rated them on on three dimensions: After scanning, the same photos were rated again on scales that assessed potential romantic desirability: For analysis, the authors estimated four models: "Journal speed dating" decisiontwo predictors: Similar but controlled for reaction time RT to the FI decision.
This will become important, as we'll see below. Regions that correlated with subjective desirability ratings: Adjustment for partner and relationship effects: Let's look at the results for the basic decision A and for subjective attractiveness B in the figure below.

Paracingulate cortex circled is the only activated region that significantly independently correlates with subsequent decision in a multiple regression including all activated regions. BBrain regions positively correlating with subjective ratings of physical attractiveness for each partner.
COverlap between brain regions related to decision and those related to attractiveness, showing substantial overlap between these variables in the paracingulate cortex. Color bars indicate t statistic.
The circled area A is called paracingulate cortex by these authors and dorsal anterior cingulate cortex ACC by many others. The paracingulate is the only region that correlated with subsequent dating decisions. An explanation for this is well beyond the scope of a single blog post. The big blob B correlated with physical attractiveness, and C shows the overlap between these two. It was important to control for the RT of first impression
Journal speed dating because activity in the ACC is sensitive to "time on task," or how long it takes to process or respond to a stimulus.
Hence, the paracingulate could merely be responsive to making dating decisions that are sometimes ambiguous or difficult. The table below shows that wasn't entirely the case, but the magnitude of the paracingulate activation was diminished when RT was controlled.
Journal speed dating wasn't true of two other brain regions ventral visual cortex, medial precuneuswhich weren't even discussed in the paper. Modified from Table 2 Cooper et al. Our friend the paracingulate responded to objective attractiveness, as judged by the entire group of participants.
In contrast, another region — 36 voxels in the rostromedial prefrontal cortex — responded to whether the potential partner was desirable to a specific participant. Distinct regions of medial prefrontal cortex mediate effects of consensus judgments and individual preferences. ARegion of paracingulate cortex significantly correlated with consensus judgments for decisions i.
Overall, the authors have tried to

Somehow I think we're missing something here Not to mention how this intersects with our past experience and future goals. Conflict monitoring and decision making: Cogn Affect Behav Neurosci. The anterior cingulate gyrus andthe mechanism of self-regulation. It makes sense that people would pay more attention to faces they liked the look of, so "Journal speed dating" can well believe that there are neural correlates of attraction but hard to tell, from such a paradigm, if they're specific to it.
That is quite sensible, but the authors ignored the activations in
