Multisensory training based on an APP for enhanced verbal working memory in older adults.

With the increasing aging population, contemporary society faces the imperative to develop approaches that efficiently delay the age-related decline in working memory capacity, which is a critical area within cognitive aging research. Nevertheless, there is insufficient evidence to support the efficacy of verbal working memory training across various sensory modalities (visual, auditory, and audiovisual) in enhancing the verbal working memory capacity of older adults. In this study, 60 healthy older adults (mean age = 67.07 ± 3.79 years, comprising 34 women and 26 men, mean education = 15.55 ± 2.53 years) were randomly assigned to one of four groups: visual verbal working memory (V-VWM) group, auditory verbal working memory (A-VWM) group, visual-auditory verbal working memory (VA-VWM) group, and a control group. The training duration spanned 12 days. We also investigated whether baseline level and education predicted the outcomes. Findings indicated that V-VWM training had a large effect on improving V-VWM task performance (Cohen's d = 1.765), A-VWM training showed a substantial effect on A-VWM task performance (Cohen's d = 1.904), and VA-VWM training demonstrated a significant effect on VA-VWM task performance (Cohen's d = 2.319) over pretest scores in older adults. Enhancements achieved through V-VWM training exhibited near transfer effects, improving performance in both A-VWM and VA-VWM tasks. In contrast, gains from A-VWM training were selectively transferred to the VA-VWM task. Furthermore, VA-VWM training led to improvements not only in V-VWM and A-VWM tasks but also extended to verbal operation span task with a significant 29.7 % increase. However, no significant transfer effects were observed for the DSF and DSB tasks across the three training groups. The maintenance effect of VA-VWM training persisted for two weeks across tasks involving VA-VWM, V-VWM, and A-VWM. The baseline of VWM span score influence the effect of V-VWM training and transfer effect of VA-VWM training. Education level did not predict the training effects of V-VWM, A-VWM, and VA-VWM. These findings highlight the nuanced effects of sensory-specific verbal working memory training in older adults, emphasizing the potential of tailored interventions to enhance specific aspects of cognitive function, while also highlighting the promising applications of mobile device training in enhancing cognitive skills among the elderly.

The Relationship between Football Participation and Sport Trait Confidence for Adolescents: A Chain-Mediated Effect of Collective Self-Esteem and Self-Esteem.

To investigate the relationship between sports participation and sport trait confidence, 1659 teenagers in primary and secondary schools who regularly play football were asked to complete the Sports Participation Scale, Collective Self-Esteem Scale, Self-Esteem Scale, and Sport Trait Confidence Scale. The results show that (1) the positive prediction of football participation on sport trait confidence is not significant; (2) collective self-esteem and self-esteem play a mediating role between football participation and sport trait confidence; (3) the mediating effect occurs through three pathways. The study provides theoretical guidance and empirical evidence for the lead and intervention of adolescent football participation on sport trait confidence. This study created a chain-mediated model to examine the mediating role of collective self-esteem and self-esteem in their relationship, as well as the impact of the two as chain mediators on football participation and sport trait confidence.

The role of offensive processes and age development for female soccer players' anticipation.

Anticipation has been confirmed as a more valid measure for recognizing talented athletes than pattern recall alone. Anticipation of offensive processes in soccer, such as counter attacks and positional attacks, is essential for the sport. Additionally, the anticipation of elements such as the soccer ball, offensive and defensive players may also be affected by varied offensive processes. In this study, we combined anticipation with the pattern recall paradigm to measure the perceptual-cognitive skills of female soccer players across different age groups and offensive processes. Adult (U23) and adolescent (U15) female soccer players were recruited to complete the pattern anticipation task using coach-rated video segments. Our results show that adult female soccer players demonstrated greater accuracy in anticipating locations during positional attacks compared to adolescents, but no significant difference was observed during counter attacks. Furthermore, location anticipation accuracy is higher in all groups towards elements of the soccer ball and offensive players, but not defensive players, during counter attacks compared to positional attacks. These findings suggest that positional attack is the main advantage in perceptual-cognitive skills for adult female soccer players. Additionally, offensive processes and elements should be carefully considered when measuring perceptual-cognitive skills.

Relationship Between the Parietal Cortex and Task Switching: Transcranial Direct Current Stimulation Combined with an Event-related Potential Study.

Task switching refers to a set of cognitive processes involved in shifting attention from one task to another. In recent years, researchers have applied transcranial direct current stimulation (tDCS) to investigate the causal relationship between the parietal cortex and task switching. However, results from available studies are highly inconsistent. This may be due to the unclear understanding of the underlying mechanisms. Therefore, the current study utilized event-related potential (ERP) analysis to investigate the modulatory effects of tDCS on task-switching processes. Twenty-four subjects were recruited to perform both predictable and unpredictable parity/magnitude tasks under anodal (RA) and sham conditions. The results showed no significant changes in behavioral performance. However, marked tDCS-induced ERP changes were observed. Specifically, for the predictable task switching, compared with the sham condition, the target-N2 component occurred significantly earlier for switch trials than repeat trials under the RA condition in males, while no difference was found in females. For unpredictable task switching, under the sham condition, the P2 peak was significantly larger for switch trials compared with repeat trials, whereas this difference was not observed under the RA condition. These results indicated the causal relationship between the right parietal cortex and exogenous adjustment processes involved in task switching. Moreover, anodal tDCS over the right parietal cortex may lead to the manifestation of gender differences.

Why Do Humble Individuals Act More Altruistically toward Foreigners: A Moderated Mediation Model.

According to the humility-helping hypothesis, the question of whether humility affects altruistic behavior has received extensive attention. However, researchers have not established many links between humility and international altruism. The study explored humility as a stable personality trait and assessed whether it encouraged international altruism. It also examined the underlying mechanism between the foregoing relationship. We recruited 940 college students aged 18-23 to participate in an anonymous online survey and obtained 929 data points. The results showed that humility has a direct impact on international altruism. They largely supported the theoretical framework of the humility-helping hypothesis on the inter-group level. We also addressed the mediating effect that identification with all humanity had in the relationship between humility and international altruism. The findings showed that two forms of empathy (empathy and group empathy) have a moderating effect, indicating that different forms of empathy should be more emphasized in different social situations. Taken together, the results show that developing people's humility and helping them to identify with all humanity are key to promoting inter-group altruism, especially for those who can empathize with other people or groups.

Relationship between parenting style and internet addiction: Interpersonal relationship problem as a mediator and gender as a moderator.

Purpose: This study assessed the moderating effect of gender on the indirect effects of positive and negative parenting styles on Internet addiction through interpersonal relationship problem. Methods: A cross-sectional survey of randomly sampled 1194 college students recruited voluntarily from three universities in China was conducted to assess the variables of positive and negative parenting styles, interpersonal relationship problem, and Internet addiction. Results: Positive parenting style, such as emotional warmth, was a protective factor for the development of Internet addiction, whereas negative parenting style, such as rejection and overprotection, was a potential risk factor for Internet addiction. Furthermore, interpersonal relationship problem completely mediated the association between positive parenting style and Internet addiction but partially mediated the relationship between negative parenting style and Internet addiction. Finally, gender moderated the indirect effect of parenting style on Internet addiction through interpersonal relationship problem. Conclusion: The correlation between positive parenting style and interpersonal relationship problem was considerably weaker among females, whereas the association between interpersonal relationship problem and Internet addiction was much stronger among females. For the prevention and intervention of Internet addiction, it is important to increase positive parenting style for males while enhancing interpersonal skills training for females. Further longitudinal studies should discuss the effects of paternal and maternal parenting styles on Internet addiction.

Can orange colour facilitate the processing of happiness? An exploration study on happiness metaphor.

Colour is a ubiquitous perceptual stimulus, and theoretical models of colour and psychological functioning posit that colour plays a key role in influencing the behaviour and mental function of a person. One investigation and two experiments investigated the colour metaphor representation of happiness concepts and the mapping mode of the colour metaphor of happiness concepts. A questionnaire was conducted to explore the relationship between colour preference and happiness. Study 2 shows that the identification of happiness words was facilitated more when words were viewed on an orange background than when viewed on a blue background. Study 3 further verifies the links of the connection between colour and happiness at the sentence level, and the orange-happiness facilitation effect was replicated. These results document a novel influence of colour on emotion recognition processes, where an orange background may facilitate the processing of the concept of happiness and provide support for conceptual metaphor theory and colour-in-context theory.

The effect of working memory load on inattentional deafness during aeronautical decision-making.

Operating an aircraft requires pilots to handle a significant amount of multi-modal information, which creates a high working memory load. Detecting auditory alarms in this high-load scenario is crucial for aviation safety. According to cognitive control load theory, an increase in working memory load may enhance distractor interference, resulting in improved detection sensitivity for task-irrelevant stimuli. Therefore, understanding the effect of working memory load on auditory alarm detection is of particular interest in aviation safety research. The studies were designed to investigate the effect of storage load and executive function load of working memory on auditory alarm detection during aeronautical decision-making through three experiments. In Experiment 1 and 2, participants performed an aeronautical decision-making task while also detecting an auditory alarm during the retention interval of a working memory task (visual-spatial, visual-verbal and auditory-verbal). In Experiment 3, participants were required to detect an auditory alarm while performing the 2-back and 3-back aeronautical decision-making tasks. Experiment 1 found that the auditory alarm sensitivity was higher in conditions of low visual-spatial working memory storage load compare to high load conditions. Experiment 2 found that a high storage load of visual-verbal working memory reduced auditory alarm sensitivity but auditory-verbal working memory load did not. Experiment 3 found that, unlike storage load, auditory alarm sensitivity was stronger under high executive function load relative to low executive function load. These findings show that working memory storage load and executive function load have different effects on auditory alarm sensitivity. The relationship between executive function and auditory alarm sensitivity supports cognitive control load theory, while the impact of the storage function on auditory alarm sensitivity does not adhere to this theory.

Influence of self-efficacy on male military pilots' capability to handle special situations: a moderated mediation model.

This study aimed to explore the mediating and moderating effects of resilience and perseverance on pilots' self-efficacy and capability of handling special situations. Using cluster sampling, 251 pilots' self-efficacy, special flight situation handling capability, resilience and perseverance were assessed using standardized scales. Pilots with high self-efficacy can improve their resilience to enhance their capability to handle special situations. An analysis was performed that included perseverance in the mediation model, and results showed that the influence of self-efficacy on special situation handling through resilience was moderated by perseverance. The relations between self-efficacy and special flight situation handling capability present a moderated mediation model. A pilot's capability of handling special situations, ensuring flight safety and combat capability may be enhanced by improving their self-efficacy, resilience, and perseverance.

How the black hole illusion environment affects operational performance at different flight phases in aviation.

The black hole illusion (BHI) is a subtype of spatial disorientation that can result in fatal consequences in aviation. Research on the BHI has generally focused on altitude deviation, and few studies have examined the effect across different flight phases. In a simulation-based experiment, 18 participants performed 12 simulated approach and landing tasks in normal and BHI environments. Flight performance was analyzed with 14 flight parameters and was compared across five points and three phases, which were referenced from a National Transportation Safety Board report and other previous studies. Results showed that multiple flight parameters were significantly impaired and that their influences varied from the initial approach to the final touchdown. In the BHI environment, participants tended to descend aggressively during the approach phase and flew a lower but similar glidepath during the last approach phase. They might have realized the abnormal situation induced by the BHI but usually were unable to recover from the dangerous maneuver in time. Additionally, the result of glide path error, one of the most commonly used variables in previous BHI research, was only significant during the last approach phase. Flight stability was also impaired in the BHI environment. This is the first study to systematically analyze the BHI effects on multiple flight parameters at different flight phases. The use of this experimental paradigm could facilitate future research to evaluate and prevent the BHI in a more comprehensive way.

The Influence of Emotion Induced by Accidents and Incidents on Pilots' Situation Awareness.

(1) Background: This study examines the differences in emotions induced by accidents and incidents as emotional stimuli and the effects on pilot situation awareness (SA) after induction. (2) Method: Forty-five jet pilots were randomly divided into three groups after which their emotions were induced using the pictures of accident, incident, and neutral stimulus, respectively. (3) Results: The conditions of accidents and incidents both induced changes in the pilots' happiness and sadness and the changes in the emotion were regulated by the emotional intelligence of pilots in the high SA group. The emotion induction, which caused a direct change in pilot's happiness and fear, resulted in conditions that indirectly affected level 1 of SA in pilots. (4) Conclusions: The research elucidates the difference between accident and incident in inducing pilot emotions, and reminds us that SA level exerts the regulating effects on the same emotional induction conditions.

Relation of emotion malleability beliefs to subjective well-being: A short-term longitudinal study.

Prior research has shown that emotion malleability beliefs are positively related to subjective well-being, but less is known about the longitudinal relationship between both variables. The present study used a two-wave longitudinal design to examine the temporal directionality of the relationship in a sample of Chinese adults. Using cross-lagged models, we found that emotion malleability beliefs predicted all three dimensions of subjective well-being (i.e. positive affect, life satisfaction, and negative affect) 2 months later. However, we did not detect any reverse or reciprocal effect between emotion malleability beliefs and subjective well-being. In addition, emotion malleability beliefs still predicted life satisfaction and positive affect after controlling for the effect of the cognitive or emotional component of subjective well-being. Our study provided primary evidence for the temporal directionality of the association between emotion malleability beliefs and subjective well-being. Implications and suggestions for future research were discussed.

Linkage of calling and burnout among Chinese airline pilots: the role of psychological capital and organizational identification.

Objectives. Burnout of airline pilots has an extremely adverse impact on their physical and mental state, their work efficiency and safe operation of airlines, and is thus an important issue in occupational safety and health. Therefore, it is crucial to identify factors that may reduce burnout among airline pilots. Drawing on conservation of resources theory, the present study investigates the relationships between calling, psychological capital, organizational identification and burnout in order to understand the mechanisms underlying pilot burnout. Method. A cross-sectional survey was conducted to measure calling, psychological capital, organizational identification and burnout among a sample consisting of 242 Chinese commercial airline pilots (age: M 31.60 years, SD 6.44). Correlation analysis, mediation analysis and moderated analysis were conducted. Results. The results showed that calling has a direct and negative effect on pilot burnout, and an indirect effect on burnout through influencing psychological capital. Moreover, organizational identification was found to positively moderate the negative relationship between calling and pilot burnout. Conclusion. This study contributes to deepening theoretical research on burnout, and provides empirical evidence for effective intervention in the burnout of airline pilots, which is beneficial to reduce pilot human error and ensure flight safety. Future research directions are also discussed.

How can proactive personality affect cabin attendants' safety behaviors? The moderating roles of social support and safety climate.

Cabin attendants are mainly responsible for maintaining in-flight safety, and they are crucial to enhance air travel safety and alleviate passenger concerns. The objective of this study is to explore relationships between proactive personality, social support, safety climate and safety behaviors among cabin attendants. A self-assessment questionnaire was used to investigate a sample of 560 cabin attendants from China Southern Airlines Ltd. The results show that proactive personality and safety climate positively influence cabin attendants' safety behaviors. Social support was found to weaken the positive effect of proactive personality on safety behaviors. Furthermore, social support and safety climate jointly moderate the relationship between proactive personality and safety behaviors, suggesting that this relationship is the strongest when the levels of social support and safety climate are both high. Theoretical and practical implications for researchers and practitioners in designing interventions and strategies to promote safety behaviors in an airline context are discussed.

The influence of time structure on number prediction motion.

Time structure refers to the ratio of time spent moving during visible segments and occluded segments in position prediction motion (PM) tasks. Recent research has found that an equal time structure can improve performance in position prediction motion tasks. However, there is no research to explore the influence of time structure on the number PM task. In three behavioural experiments, this study explored whether an equal time structure improved number prediction motion performance, as it did in position tasks. The results demonstrated that an equal time structure could improve participant performance in the number prediction motion task (Experiment 1). However, equal time structures did not improve task performance when the numbers before the transition number were presented regularly one by one (Experiment 2). Experiment 3 showed that participants could actively take advantage of equal time information when the numbers before the transition number were presented irregularly. These findings demonstrated that when the number sequence was not presented in order, people could use the time structure heuristics to estimate completion time estimates (CTEs). People could sub-vocally count through mental number space when the number sequence was presented in order.

China's country image in the eyes of international students from central Asian countries.

This study aimed to investigate the conceptualization and measurement of China's country image (CI) as well as its effects on the economic image, product image, national image and residence intention of individuals. A total of 297 international students from central Asia were recruited to complete an online survey. The confirmatory factor analysis of CI scale showed that CI is a multidimensional construct consisting of a cognitive component (further be divided into government image, international image, and social image) and an affective component. Participants' ratings on China's CIs before and after coming to China were compared by using a repeated-measures ANOVA and paired sample t-tests, and the results showed a significant difference in government image and international image but no significant difference in social image. The regression analysis showed that CI significantly predicted the economic image, product image, national image and individual's residence intention. This study demonstrated a theoretical insight of CI research and could potentially contribute to optimizing strategies to improve the country reputation.

Cognitive Style and Flight Experience Influence on Confirmation Bias in Lost Procedures.

BACKGROUND: Accident analysis and empirical research have shown that the decision-making process of pilots after becoming lost is adversely affected by confirmation bias; this constitutes a serious threat to aviation safety. However, the underlying mechanism of confirmation bias in the context of lost procedures are still unclear.METHODS: This study used scenario-based map-reading tasks to conduct two experiments to explore the mechanism of confirmation bias in the lost procedures. In Experiment 1, 34 undergraduate students and 28 flying cadets were enrolled in a formal experiment to examine the effects of verbal-imagery cognitive style, experience level, and their interaction on confirmation bias. In Experiment 2, we further explored the influence of strategy as a core component of experience on confirmation bias with 26 flying cadets.RESULTS: The study found that individuals were subject to confirmation bias in lost procedures. Visualizers (M = 0.78, SD = 0.75) were almost twice as likely to select the disconfirmatory features than verbalizers (M = 0.37, SD = 0.49). Visualizers exhibited a lower degree of confirmation bias than verbalizers, and experience helps verbalizers to reduce their degree of confirmation bias. The protective effect of experience mainly lies in individuals' choice of strategy.DISCUSSION: Future aviation safety campaigns could be aimed at adopting a candidate selection process that focuses more on psychological attributes by testing for cognitive style, and enriching individual experience through adequate training. Such measures would reduce confirmation bias.Xu Q, Wang M, Wang H, Liu B, You X, Ji M. Cognitive style and flight experience influence on confirmation bias in lost procedures.

Are boys associated with weapons and girls associated with kitchenware? The extent to which gender stereotypes regarding adults extend to children.

Adults' views of children based on gender stereotypes can affect their communication with children, which can affect children's development; therefore this study explores the extent to which adults extend gender stereotypes regarding adults to children. This study conducted four experiments using Chinese adult undergraduate student participants. Using adult faces as prime stimuli and images of weapons (guns) and kitchenware (spatulas) as target objects, Experiment 1 found that Chinese adults associate men with weapons and women with kitchenware. Experiment 2 found the same results when participants were primed with the faces of 14-year-old girls and boys. In Experiment 3, we found that participants held gender stereotypes toward 12-year-old girls, associating them with kitchenware objects. However, when using the faces of 10-year-old children as prime stimuli in Experiment 4, we found that participants did not hold the same gender stereotypes toward 10-year-old children. In Experiment 5, we used adult faces and the faces of 10-year-old children as simultaneous prime stimuli and found that weapons were only associated with adult men and kitchenware with adult women. These results indicate that the gender stereotypes hold true in Chinese cultures, and that these stereotypes can extend to children as young as 12 years old.

Multitarget high-definition transcranial direct current stimulation improves response inhibition more than single-target high-definition transcranial direct current stimulation in healthy participants.

Prior studies have focused on single-target anodal transcranial direct current stimulation (tDCS) over the right inferior frontal gyrus (rIFG) or pre-supplementary motor area (pre-SMA) to improve response inhibition in healthy individuals. However, the results are contradictory and the effect of multitarget anodal stimulation over both brain regions has never been investigated. The present study aimed to investigate the behavioral and neurophysiological effects of different forms of anodal high-definition tDCS (HD-tDCS) on improving response inhibition, including HD-tDCS over the rIFG or pre-SMA and multitarget HD-tDCS over both areas. Ninety-two healthy participants were randomly assigned to receive single-session (20 min) anodal HD-tDCS over rIFG + pre-SMA, rIFG, pre-SMA, or sham stimulation. Before and immediately after tDCS intervention, participants completed a stop-signal task (SST) and a go/nogo task (GNG). Their cortical activity was recorded using functional near-infrared spectroscopy (fNIRS) during the go/nogo task. The results showed multitarget stimulation produced a significant reduction in stop-signal reaction time (SSRT) relative to baseline. The pre-to-post SSRT change was not significant for rIFG, pre-SMA, or sham stimulation. Further analyses revealed multitarget HD-tDCS significantly decreased SSRT in both the high-performance and low-performance subgroups compared with the rIFG condition which decreased SSRT only in the low-performance subgroup. Only the multitarget condition significantly improved neural efficiency as indexed by lower △oxy-Hb after stimulation. In conclusion, the present study provides important preliminary evidence that multitarget HD-tDCS is a promising avenue to improve stimulation efficacy, establishing a more effective montage to enhance response inhibition relative to the commonly used single-target stimulation.
