“…The only negative association between trait impulsivity and MTG volume was found in a study with more female subjects (Muhlert & Lawrence, 2015). Moreover, given that the STG and MTG are involved in decision‐making (Owens et al, 2017) and performance in delay discounting tasks varies across genders (Mei, Tian, Xue, & Li, 2017), our findings in the STG and MTG might shed light on gender distinctions in brain structural variations related to decisional impulsivity.…”

Trait impulsivity is a multifaceted personality characteristic that contributes to maladaptive life outcomes. Although a growing body of neuroimaging studies have investigated the structural correlates of trait impulsivity, the findings remain highly inconsistent and heterogeneous. Herein, we performed a systematic review to depict an integrated delineation of gray matter (GM) substrates of trait impulsivity and a meta‐analysis to examine concurrence across previous whole‐brain voxel‐based morphometry studies. The systematic review summarized the diverse findings in GM morphometry in the past literature, and the quantitative meta‐analysis revealed impulsivity‐related volumetric GM alterations in prefrontal, temporal, and parietal cortices. In addition, we identified the modulatory effects of age and gender in impulsivity‐GM volume associations. The present study advances understanding of brain GM morphometry features underlying trait impulsivity. The findings may have practical implications in the clinical diagnosis of and intervention for impulsivity‐related disorders.

Neural Responses to Reward in a Gambling Task: Sex Differences and Individual Variation in Reward-Driven Impulsivity

Previous work suggests sex differences in reward sensitivity. However, it remains unclear how men and women differ in the neural processes of reward-driven impulsivity. With a data set of 968 subjects (502 women) curated from the Human Connectome Project, we investigated sex differences in regional activations to reward and to punishment in a gambling task. Individual variations in reward-driven impulsivity were quantified by the difference in reaction time (RT) between reward and punishment blocks in the gambling task, as well as by a behavioral measure of delay discounting. At a corrected threshold, men and women exhibited significant differences in regional activations to reward and to punishment. Longer RTs during reward vs. punishment blocks, indicative of more cautious responding, were associated with left-hemispheric lateral prefrontal cortical activation to reward in men but not women. Steeper discounting was associated with higher activation to reward in the right-hemispheric dorsal anterior cingulate cortex and angular gyrus in women but not men. These sex differences were confirmed in slope tests. Together, the results highlight the sex-specific neural processes of reward-driven impulsivity with left-hemispheric prefrontal cortex supporting impulse control in men and right-hemispheric saliency circuit playing a more important role in diminished impulse control in women.

Penelitian yang ada menyatakan perempuan dan laki-laki mempunyai karakteristik yang berbeda saat memproses informasi (Mei, Tian, Xue, & Li, 2017). Terjesen, Couto, & Fransisco (2016) menemukan bahwa keberadaan direktur independen wanita meningkatkan efektifitas dewan direksi sehingga diharapkan akan meningkatkan nilai perusahaan (Campbell & Mínguez-Vera, 2008).…”

terhadap Kinerja Pemerintahan? Tujuan penelitian ini adalah menguji pengaruh karakteristik kepala daerah terhadap kinerja pemerintah daerah di Indonesia. Uji regresi data panel digunakan sebagai metode penelitian. Hasil pengujian menunjukkan kepala daerah yang mempunyai umur lebih tinggi dan masa kerja yang lebih lama serta gender perempuan dapat memberikan kontribusi positif terhadap kinerja pemerintah daerah. Kepala daerah menggunakan pengalaman mereka untuk meningkatkan kinerja pemerintah daerah. Selain itu, penelitian ini juga menunjukkan bahwa tingkat pendidikan kepala daerah tidak memberikan dampak positif terhadap kinerja karena mereka cenderung memutuskan kebijakan berdasarkan prinsip dan lingkungan sosial.
