Consciousness and Cognition > 2018 > 58 > C > 158-169

The prediction of emotion has been explored in a variety of functional brain imaging and neurophysiological studies. However, an overall picture of the areas involved this process remains unexploited. Here, we quantitatively summarized the published literature on emotional prediction using activation likelihood estimation (ALE) in functional magnetic resonance imaging (fMRI). Furthermore, the current...

Yangu Pan, Yu Hu, Dajun Zhang, Guangming Ran, more

Children and Youth Services Review > 2017 > 83 > C > 218-225

We examined whether psychological suzhi mediated the associations between attachment (paternal, maternal, and peer) and young adolescents' behavior (internalizing, externalizing, and prosocial) in a longitudinal study. Psychological suzhi reflects the positive psychological traits that facilitate adolescents' positive adaptation to the school and social environment. Five hundred and ninety-five junior...

Journal of Nuclear Materials > 2017 > 492 > C > 189-194

Tritium release behavior from the Li₄SiO₄ pebbles with high densities (∼96%TD) and large grain sizes (100–300 μm) fabricated by a melt-based method (the M-OSi sample) was investigated through out-of-pile experiments. Another batch of Li₄SiO₄ pebbles with relatively low densities (∼86%TD) and small grain sizes (10–50 μm) fabricated by a wet method (the W-OSi sample) was used for comparative study....

Annihilation behavior of irradiation defects in Li4SiO4 irradiated with high thermal neutron fluence

Guangming Ran, Chengjian Xiao, Xiaojun Chen, Yu Gong, more

Journal of Nuclear Materials > 2017 > 491 > C > 43-47

The annihilation behavior of irradiation defects in Li₄SiO₄ which were irradiated with thermal neutrons to a high fluence was studied by electron spin resonance (ESR). It was observed that the ratio of O-related centers to E'-centers increased with increasing annealing temperature. The total irradiation defects were annihilated through two processes, namely the fast (120–250 °C, 70%) and the slow...

Do attachment patterns predict aggression in a context of social rejection? An executive functioning account

Yuanxiao Ma, Haijing Ma, Xu Chen, Guangming Ran, more

Aggressive Behavior > 43 > 4 > 408 - 418

People tend to respond to rejection and attack with aggression. The present research examined the modulation role of attachment patterns on provoked aggression following punishment and proposed an executive functioning account of attachment patterns’ modulating influence based on the General Aggression Model. Attachment style was measured using the Experiences in Close Relationships inventory. Experiments...

The model of children's dual process of personal domain deontic rules in conflict situations

Le Zhao, Guangming Ran

Personality and Individual Differences > 2017 > 111 > C > 6-12

Children are usually confronted with situations in which their desires to do something conflict with deontic rules in the personal domain. Based on a dual process approach, this study pointed out that, children's processing of personal domain deontic rules was a dual process only in conflict situations, and only until their adolescence. The dual-process model was the one featuring the serial processing...

Tritium release in Li4SiO4 and Li4.2Si0.8Al0.2O4 ceramics

Linjie Zhao, Xinggui Long, Shuming Peng, Xiaojun Chen, more

Journal of Nuclear Materials > 2016 > 482 > C > 42-46

Li_4+xSi_1−xAl_xO₄ solid solution materials, which were designed as the advanced tritium breeders, were obtained by indirect solid state reactions. The behaviors of tritium release from Li₄SiO₄ and Li_4.2Si_0.8Al_0.2O₄ powders were investigated by temperature programmed desorption. The tritium release curves show different characteristics for the Li₄SiO₄ and Li_4.2Si_0.8Al_0.2O₄ ceramics. The main tritium...

Attachment and internalizing symptoms: The mediating role of regulatory emotional self-efficacy among Chinese young adolescents

Yangu Pan, Dajun Zhang, Yanling Liu, Guangming Ran, more

Personality and Individual Differences > 2016 > 101 > C > 360-365

The aim of this study was to test whether the association between attachment and internalizing symptoms was mediated by regulatory emotional self-efficacy. A total of 763 Chinese young adolescents (48% male; aged 11–17years, M=12.79years, SD=0.75) completed measures of paternal, maternal, and peer attachment and regulatory emotional self-efficacy, while each adolescent's parent completed a measure...

Prediction and unconscious attention operate synergistically to facilitate stimulus processing: An fMRI study

Guangming Ran, Xu Chen, Xiaojun Cao, Qi Zhang

Consciousness and Cognition > 2016 > 44 > C > 41-50

There is considerable evidence that prediction and attention aid perception. However, little is known about the possible neural mechanisms underlying the impact of prediction and unconscious attention on perception, probably due to the relative neglect of unconscious attention in scholarly literature. Here, we addressed this issue using functional magnetic resonance imaging (fMRI). We adopted a variant...

Journal of Nuclear Materials > 2015 > 466 > C > 316-321

The correlation between water desorption and tritium release from Li₄SiO₄ pebbles was studied by temperature programmed desorption. The released water and tritium from irradiated samples were monitored simultaneously. The main peak for tritium release from the irradiated samples that were exposed to air for more than a month, was shifted from 500 to about 250 °C, as compared to that from the unexposed...

Unconscious attention modulates the silencing effect of top-down predictions

Xu Chen, Guangming Ran, Qi Zhang, Tianqiang Hu

Consciousness and Cognition > 2015 > 34 > Complete > 63-72

The brain is considered to be proactive in that it continuously generates predictions about external environment stimuli. Recent Bayesian models of perception have demonstrated that prediction and attention operate synergistically to optimize stimulus processing. However, the relation between prediction and unconscious attention remains unclear given the relative neglect of unconscious attention in...
