Career Adaptability and Academic Achievement Among Chinese High School Students: A Person-centered Longitudinal Study.

Career adaptability, essential for high school students' career development, is closely associated with academic achievement. However, it is still unclear whether there exist multiple subgroups among Chinese high school students that exhibit distinct combinations of the career adaptability dimensions and whether these subgroups display significant differences in academic achievement. Using latent profile analysis, this study identified career adaptability profiles in Chinese high school students and examined their effects on academic achievement through a longitudinal design. Chinese high school students (Wave 1: N = 1783, 42.9% boys, Mage = 15.17, SD = 0.86; Wave 2: N = 1395, 42.9% boys, 82.4% science students, Mage = 16.19, SD = 0.88) completed a packet of measures on two occasions at eight-month intervals. Career adaptability was assessed at Wave 1, and academic achievement was assessed at Wave 2. Five distinct career adaptability profiles were identified: (1) Low control and confidence; (2) Below average; (3) Control dominant and low confidence; (4) Above average; (5) High. Profiles of career adaptability displayed significant differences in academic achievement. High, Above average, and Control dominant and low confidence students' achievements were significantly higher than Low control and confidence students. These findings indicate that students with an overall high level of career adaptability or more robust career control are more likely to achieve higher academic achievement. In addition, level (average scores of all dimensions across different profiles) and shape (distinct forms displayed by the specific combination of dimensions) effects exist in the influence of career adaptability profiles on academic achievement. This highlights the dynamic and diverse nature of adolescent career development within the Chinese high school context.

Integrating the pattern of negative emotion processing and acute stress response with childhood stress among healthy young adults.

Childhood adversity might impair corticolimbic brain regions, which play a crucial role in emotion processing and the acute stress response. The dimensional model of childhood adversity proposed that deprivation and threat dimensions might associated with individuals' development through different mechanisms. However, few studies have explored the relationship between different dimensions of childhood stress, emotion processing, and acute stress reactivity despite the overlapping brain regions of the last two. With the aid of the event-related potentials technique, we explore whether negative emotion processing, which might be particularly relevant for adaptive stress responding among individuals with adverse childhood experience, mediates the relationship between dimensional childhood stress and acute stress response. Fifty-one young adults completed a free-viewing task to evaluate neural response to negative stimuli measured by late positive potential (LPP) of ERPs (Event-related potentials). On a separate day, heart rate and salivary cortisol were collected during a social-evaluative stress challenge (i.e. TSST, Trier Social Stress Test). After the TSST, the childhood trauma questionnaire was measured to indicate the level of abuse (as a proxy of threat) and neglect (as a proxy of deprivation) dimensions. Multiple linear regression and mediation analysis were used to explore the relationship among childhood stress, emotion processing, and acute stress response. Higher level of childhood abuse (but not neglect) was distinctly related to smaller LPP amplitudes to negative stimuli, as well as smaller heart rate reactivity to acute stress. For these participants, smaller LPP amplitudes were linked with smaller heart rate reactivity to acute stress. Furthermore, decreased LPP amplitudes to negative stimuli mediated the relationship between higher level of childhood abuse and blunted heart rate reactivity to stress. Consistent with the dimensional model of childhood stress, our study showed that childhood abuse is distinctly associated with neural as well as physiological response to threat. Furthermore, the blunted neural response to negative stimuli might be the underlying mechanism in which childhood abuse leads to the blunted acute stress response. Considering that all the participants are healthy in the present study, the blunted processing of negative stimuli might rather reflect adaptation instead of vulnerability, in order to prevent stress overshooting in the face of early-life threatening experiences.

Algebra dissociates from arithmetic in the brain semantic network.

BACKGROUND: Mathematical expressions mainly include arithmetic (such as 8 - (1 + 3)) and algebra (such as a - (b + c)). Previous studies have shown that both algebraic processing and arithmetic involved the bilateral parietal brain regions. Although previous studies have revealed that algebra was dissociated from arithmetic, the neural bases of the dissociation between algebraic processing and arithmetic is still unclear. The present study uses functional magnetic resonance imaging (fMRI) to identify the specific brain networks for algebraic and arithmetic processing. METHODS: Using fMRI, this study scanned 30 undergraduates and directly compared the brain activation during algebra and arithmetic. Brain activations, single-trial (item-wise) interindividual correlation and mean-trial interindividual correlation related to algebra processing were compared with those related to arithmetic. The functional connectivity was analyzed by a seed-based region of interest (ROI)-to-ROI analysis. RESULTS: Brain activation analyses showed that algebra elicited greater activation in the angular gyrus and arithmetic elicited greater activation in the bilateral supplementary motor area, left insula, and left inferior parietal lobule. Interindividual single-trial brain-behavior correlation revealed significant brain-behavior correlations in the semantic network, including the middle temporal gyri, inferior frontal gyri, dorsomedial prefrontal cortices, and left angular gyrus, for algebra. For arithmetic, the significant brain-behavior correlations were located in the phonological network, including the precentral gyrus and supplementary motor area, and in the visuospatial network, including the bilateral superior parietal lobules. For algebra, significant positive functional connectivity was observed between the visuospatial network and semantic network, whereas for arithmetic, significant positive functional connectivity was observed only between the visuospatial network and phonological network. CONCLUSION: These findings suggest that algebra relies on the semantic network and conversely, arithmetic relies on the phonological and visuospatial networks.

Blunted reward responsiveness prospectively predicts emotional distress when exposed to a naturalistic stressor.

Both stress and blunted reward responsiveness have been identified as core risk factors of depression. Whether blunted reward responsiveness increases psychological vulnerability to real-life stress from a dynamic perspective (from stress reactivity to recovery) has not been investigated. By utilizing a real-world stressful event (i.e. the final examination), this study aimed to explore the role of reward responsiveness in the stress-emotional distress relationship during stress reactivity and recovery phases. We followed 57 undergraduates with three assessments, from six weeks before examination weeks (T1, baseline), one day before the examinations (T2) to two weeks after the examinations (T3), therefore, covering stress reactivity (T1 to T2) and recovery (T2 to T3) phases. At baseline, reward responsiveness was measured as the Reward Positivity (RewP) in the doors task. Stress and emotional distress (anxiety and depression) were reported at T1, T2 and T3 to capture their dynamic changes. Results showed that self-report stress levels significantly increased from T1 to T2 (stress reactivity phase) and decreased from T2 to T3 (stress recovery phase). Furthermore, blunted reward responsiveness at baseline prospectively predicted emotional distress during the stress reactivity phase but not the recovery phase. Specifically, during the stress reactivity phase, higher perceived stress was associated with greater anxiety and depression only in participants with relatively smaller residual RewP amplitudes but not in participants with relatively larger residual RewP amplitudes. Our study demonstrated that a blunted reward responsiveness is a vulnerable factor of depression, especially when exposed to stress. Our findings provide insights into prevention and intervention for stress-related disturbance.

AoA-L2 and Usage-L2 modulate the functional neuroplasticity of the subcortex.

Previous studies revealed structural differences in subcortical regions between monolinguals and bilinguals; however, whether the functional neuroplasticity of the subcortex is modulated by different bilingual experiences remains unclear. Here, we examined the effect of age of second language acquisition (AoA-L2) and usage of L2 (Usage-L2) on subcorto-cortical and intra-subcortical functional connectivity (FC) in bilinguals by using resting-state fMRI data. The relations between brain measurements and bilingual experiences were revealed by using multiple regression analysis. We found that increased AoA-L2 was mainly related to decreased subcortical FC involving the anterior thalamus, basal ganglia, and hippocampus. Increased Usage-L2 at home was mainly associated with decreased subcortical FC of the amygdala, globus pallidus, hippocampus, and nucleus accumbens. The FC of these subcortical regions displayed a positive relation with Usage-L2 in social settings. These findings reveal that bilingual experiences modulate the functional neuroplasticity of the subcortex in different ways.

Parenting styles and psychological resilience: The mediating role of error monitoring.

Parenting styles are associated with children's psychological resilience. However, the underlying mechanisms of this have not been investigated. Parenting styles influence how individuals respond to self-inflicted errors, and error monitoring is related to psychological resilience. Therefore, this study proposed that error monitoring might be a bridging factor between parenting styles and psychological resilience. Seventy-two young healthy adults were recruited for this study. Parenting styles were assessed using the Parental Bonding Instrument, and psychological resilience was measured using the Connor-Davidson Resilience Scale. Error monitoring was investigated in the Flanker task using event-related potentials (ERPs), and two error-related components of ERPs were measured: error-related negativity (ERN) and error positivity. Mediation analyses showed that the ERN partially mediated the relationship between parenting styles and psychological resilience. Specifically, a higher level of self-reported parental overprotection was related to larger ERN amplitude, which in turn was associated with lower psychological resilience. Additionally, a higher level of self-reported parental allowance of autonomy was related to lower ERN amplitude, which in turn was linked to higher psychological resilience. These results suggest that shaping children's sensitivity in early automatic error detection is one possible mechanism through which parental styles influence their psychological resilience.

Linking Mild Childhood Adversity with Conflict and False Feedback Monitoring.

It was proposed that dimensions of childhood adversity (i.e., deprivation and threat) have distinct effects on neural development and function. Present study examined the relationships between mild deprivation/threat and performance monitoring among undergraduate students without psychiatric diagnoses. By using event-related potentials (ERPs), 78 participants underwent a modified Flanker task in which false feedback on approximately 10% of the correct response trials was administered. The dynamic stages of performance monitoring in this task were differentiated into interference monitoring, feedback processing, and behavior adjustment. Childhood adversity was assessed by a Childhood Trauma Questionnaire (CTQ), which was further divided into subscales of neglect (as a proxy for deprivation dimension) and abuse (as a proxy for threat dimension). Our results showed that higher score of childhood neglect was associated with more interference cost indicated by longer RT to interference trials at the behavioral level, and altered interference monitoring indicated by smaller N2 amplitude to interference trials at the neural level. Meanwhile, higher score of childhood abuse was related to smaller P3 amplitude to unexpected negative feedback. These results suggested that mild childhood deprivation might be associated with altered processing of interference monitoring, while mild childhood threat might be linked to lower electrophysiological response to unexpected negative feedback among young adults without psychiatric disorders.

Adaption and validation of the Perceived Control of Internal States Scale (PCOISS) in Chinese adults: a cross-sectional study.

BACKGROUND: Perceived control of internal states is important for disease prevention, stress buffering and life adaptability. However, there is no psychometric scale to measure control beliefs over internal states in China. This study aimed to adapt and validate the Perceived Control of Internal States Scale (PCOISS) in a large sample of Chinese adults. METHODS: Data was collected through a big project, in which a cross-sectional online survey was conducted nationwide in China using a powerful Chinese online survey platform named WenJuanXing ( https://www.wjx.cn/ ). We translated the PCOISS into Chinese (C-PCOISS) with the forward-backward translation procedure. For the first time of the survey, a sample of 2709 participants (Sample 1) was valid for final analysis. Sample 1 was split into two datasets for principal component analysis (PCA) (nA = 1355) and confirmatory factor analyses (CFA) (nB = 1354) to determine potential factor structure. The scale's validity (i.e., discriminant validity, convergent validity, criterion validity) and internal consistency reliability were evaluated. Among the 1354 respondents (nB), 761 (nC = 761) participated in the follow-up second wave of the survey to assess a cross-sectional test-retest reliability. RESULTS: The C-PCOISS retained 14 items. PCA yielded a three-factor model which was supported with the best fit indices in CFA. The C-PCOISS had satisfactory internal consistency with Cronbach's alpha coefficients of 0.86, 0.78 and 0.72 for three subscales, respectively. The scale also showed adequate test-retest reliability (Pearson correlations coefficient of 0.64, 0.62 and 0.54 with p < 0.001 for three subscales, respectively). Three factors of the C-PCOISS were positively associated with positive affect, and negatively associated with negative affect, depression, compulsion-anxiety and perceived stress. CONCLUSIONS: The C-PCOISS is reliable and valid for measuring control beliefs over internal states in Chinese adults.

Examining the Differential Role of General and Specific Processing Speed in Predicting Mathematical Achievement in Junior High School.

Processing speed is divided into general (including perceptual speed and decision speed) and specific processing speed (including reading fluency and arithmetic fluency). Despite several study findings reporting the association between processing speed and children's mathematical achievement, it is still unclear whether general or specific processing speed differentially predicts mathematical achievement. The current study aimed to examine the role of general and specific processing speed in predicting mathematical achievements of junior high school students. Cognitive testing was performed in 212 junior school students at the beginning of the 7th grade year, along with assessment of general and specific processing speed. Relevant academic achievement scores were also recorded at the end of the 7th and 9th grade years. Hierarchical regression analyses showed that specific processing speed made a significant unique contribution in mathematical achievement by the end of the 7th grade and could significantly predict mathematical achievements in the high school entrance examinations by end of the 9th grade after controlling for age, gender, and general cognitive abilities. However, general processing speed could not predict mathematical achievements. Moreover, specific processing speed could significantly predict all academic achievements for both the 7th and 9th grade. These results demonstrated that specific processing speed, rather than general processing speed, was able to predict mathematical achievement and made a generalised contribution to all academic achievements in junior school. These findings suggest that specific processing speed could be a reflection of academic fluency and is therefore critical for long-term academic development.

Three stages of facial expression processing: ERP study with rapid serial visual presentation.

Electrophysiological correlates of the processing facial expressions were investigated in subjects performing the rapid serial visual presentation (RSVP) task. The peak latencies of the event-related potential (ERP) components P1, vertex positive potential (VPP), and N170 were 165, 240, and 240 ms, respectively. The early anterior N100 and posterior P1 amplitudes elicited by fearful faces were larger than those elicited by happy or neutral faces, a finding which is consistent with the presence of a 'negativity bias.' The amplitude of the anterior VPP was larger when subjects were processing fearful and happy faces than when they were processing neutral faces; it was similar in response to fearful and happy faces. The late N300 and P300 not only distinguished emotional faces from neutral faces but also differentiated between fearful and happy expressions in lag2. The amplitudes of the N100, VPP, N170, N300, and P300 components and the latency of the P1 component were modulated by attentional resources. Deficient attentional resources resulted in decreased amplitude and increased latency of ERP components. In light of these results, we present a hypothetical model involving three stages of facial expression processing.

Green synthesis of gold nanoparticle/gelatin/protein nanogels with enhanced bioluminescence/biofluorescence.

Here we report the green synthesis of gelatin/protein hybrid nanogels containing gold nanoparticles (AuNPs) that collectively exhibit metal-enhanced luminescence/fluorescence (MEL/MEF). The gelatin/protein nanogels, prepared by genipin cross-linking of preformed gelatin/protein polyion complexes (PICs), exhibited sizes ranging between 50 and 200 nm, depending on the weight ratio of gelatin and protein. These nanogels serve as reducing and stabilizing agents for the AuNPs, allowing for nucleation in a gel network that exhibits colloidal stability and MEL/MEF. AuNP/gelatin/HRP and AuNP/gelatin/LTF nanogels presented an ~11-fold enhancement of bioluminescence in an HRP-luminol system and a ~50-fold fluorescence enhancement when compared to free LTF in cell uptake experiments. These hybrid nanogels show promise for optically enhanced diagnosis and other therapeutic applications.

Event-Related Potential Responses to Beloved and Familiar Faces in Different Marriage Styles: Evidence from Mosuo Subjects.

Research on familiar face recognition has largely focused on the neural correlates of recognizing a beloved partner or family member. However, no research has explored the effect of marriage style on the recognition of a beloved partner's face, especially in matriarchal societies. Here, we examined the time course of event-related potentials (ERP) in response to the face of a beloved partner, sibling, or unknown person in a sample of individuals from the matriarchal Mosuo tribe. Two groups were assessed: intermarriage and walking marriage groups (i.e., couples in a committed relationship who do not cohabitate during the daytime). In agreement with previous reports, ERP results revealed more positive VPP, N250, and P300 waveforms for beloved faces than sibling faces in both groups. Moreover, P300 was more positive for beloved partner versus sibling faces; however, this difference emerged at fronto-central sites for the walking marriage group and at posterior sites for the intermarriage group. Overall, we observed that marriage style affects the later stage processing of a beloved partner's face, and this may be associated with greater affective arousal and familiarity.

The time course of implicit processing of erotic pictures: an event-related potential study.

The current study investigated the time course of the implicit processing of erotic stimuli using event-related potentials (ERPs). ERPs elicited by erotic pictures were compared with those by three other types of pictures: non-erotic positive, negative, and neutral pictures. We observed that erotic pictures evoked enhanced neural responses compared with other pictures at both early (P2/N2) and late (P3/positive slow wave) temporal stages. These results suggested that erotic pictures selectively captured individuals' attention at early stages and evoked deeper processing at late stages. More importantly, the amplitudes of P2, N2, and P3 only discriminated between erotic and non-erotic (i.e., positive, neutral, and negative) pictures. That is, no difference was revealed among non-erotic pictures, although these pictures differed in both valence and arousal. Thus, our results suggest that the erotic picture processing is beyond the valence and arousal.

Fuzzy forecasting based on fuzzy-trend logical relationship groups.

In this paper, we present a new method to predict the Taiwan Stock Exchange Capitalization Weighted Stock Index (TAIEX) based on fuzzy-trend logical relationship groups (FTLRGs). The proposed method divides fuzzy logical relationships into FTLRGs based on the trend of adjacent fuzzy sets appearing in the antecedents of fuzzy logical relationships. First, we apply an automatic clustering algorithm to cluster the historical data into intervals of different lengths. Then, we define fuzzy sets based on these intervals of different lengths. Then, the historical data are fuzzified into fuzzy sets to derive fuzzy logical relationships. Then, we divide the fuzzy logical relationships into FTLRGs for forecasting the TAIEX. Moreover, we also apply the proposed method to forecast the enrollments and the inventory demand, respectively. The experimental results show that the proposed method gets higher average forecasting accuracy rates than the existing methods.

Emotional influences on time perception: evidence from event-related potentials.

This study examined the influence of emotion on time perception and its neural correlates by measuring event-related potentials. Participants were asked to discriminate a previously memorized 700 ms 'standard' duration from 490, 700 and 910 ms, which were presented by emotional and neutral faces. The results showed decreased contingent negative variation potentials, which index timing, for emotional conditions versus the neutral condition. In addition, under the emotional conditions, the P160 and P240 amplitudes were enhanced and the N230 amplitude was decreased. These findings suggest that temporal processing can be modulated by emotion, even within 200 ms of the stimulus onset, and that the attentional bias for emotion attenuates the cognitive resources for time perception.

Human brain responsivity to different intensities of masked fearful eye whites: an ERP study.

Previous studies have shown differential event-related potentials (ERPs) to intensities of fearful facial expressions. There are indications that the eyes may be particularly relevant for the recognition of fearful expressions, even the amount of white sclera exposed above and on sides of the dark pupil could activate the amygdala response. To investigate whether the ERP differences between intensities of fearful expressions are driven by the differential salience of the eyes in the fearful faces, ERPs were measured within a backward masking paradigm, where observers were asked to do a gender-decision task with male and female neutral faces. The emotional stimuli used were low-intensity (50%), prototypical (100%), and caricatured (150%) fearful eye whites that were derived from corresponding intensities of fearful faces respectively. Three groups of white squares that have the same pixels as the eye whites were created as control conditions. Analysis of the ERP data showed a linear increase in amplitudes of the parietal-occipital P120 by three intensities of fearful eye whites. These ERP effects were proved sensitive to intensities of negative emotions but not to the simple physical features as the same patterns of differences were not observed on white squares. Larger parietal-occipital P250 amplitudes were observed for caricatured 150% than low-intensity 50% fearful eye whites. It might reflect the subcortical pathway of emotion-specific, fearful processing. The results demonstrate that the human brain is sensitive to intensities of fear, even if just shown intensities of fearful eye white in the absence of awareness.
