A Role of DLPFC in the Learning Process of Human Mate Copying.

Zhuang JY, Xie J, Hu D, Fan M, Zheng L - Front Psychol (2016)

Bottom Line: In the current study, we conducted a behavioral experiment to test the mate coping effect and a functional magnetic resonance imaging (fMRI) experiment to test the neural basis involved in the social learning process of mate copying.In the behavioral experiment, participants were asked to rate the attractiveness of isolated opposite-sex (potential mates) facial photographs, then shown the targets associating with a neutral-faced model with textual cues indicating the models' attitude (interested vs. not-interested) toward the potential mates, and then asked to re-evaluate the potential mates' attractiveness.The mate copying effect was confirmed in the behavioral experiment -greater increase in attractiveness ratings was observed for opposite-sex photographs in the interested than in the not-interested condition.

ABSTRACT
In the current study, we conducted a behavioral experiment to test the mate coping effect and a functional magnetic resonance imaging (fMRI) experiment to test the neural basis involved in the social learning process of mate copying. In the behavioral experiment, participants were asked to rate the attractiveness of isolated opposite-sex (potential mates) facial photographs, then shown the targets associating with a neutral-faced model with textual cues indicating the models' attitude (interested vs. not-interested) toward the potential mates, and then asked to re-evaluate the potential mates' attractiveness. Using a similar procedure as the behavioral experiment, participants were scanned while observing the compound images in the fMRI experiment. The mate copying effect was confirmed in the behavioral experiment -greater increase in attractiveness ratings was observed for opposite-sex photographs in the interested than in the not-interested condition. The fMRI results showed that the dorsolateral prefrontal gyrus (DLPFC) was significantly active in the comparison of interested > not-interested condition, suggesting that a cognitive integration and selection function may be involved when participants process information from conditions related to mate copying.

Compound images and Procedure of the fMRI experiment. Block design with four blocks for each condition. Each block contained eight compound images of the same type. Two kinds of blocks were alternated between each other, with the order of the blocks counterbalanced across participants. A black fixation cross appeared in the center of the screen during the 24-s pre-block rest periods.

Figure 1: Compound images and Procedure of the fMRI experiment. Block design with four blocks for each condition. Each block contained eight compound images of the same type. Two kinds of blocks were alternated between each other, with the order of the blocks counterbalanced across participants. A black fixation cross appeared in the center of the screen during the 24-s pre-block rest periods.

Mentions: Photographs were edited in Adobe Photoshop to create dual-image compounds (300 × 400 pixels). Each compound image included one male and one female photograph, which were chosen randomly and arranged side by side against a gray background (Figure 1). The side on which the female face was displayed was counterbalanced across the compounds. In total, 64 compound images were used in the experiment.
