AI Article Synopsis
- The study aimed to investigate how cognitive styles, specifically field-dependent versus field-independent, affect optokinetic illusion among military university students.
- One hundred students were tested using the Rod and Frame Test, and based on their scores, they were divided into two groups to experience optokinetic stimulation at various speeds.
- Results showed that field-dependent individuals had shorter latent periods and different response patterns to the illusion compared to their field-independent counterparts, indicating cognitive style significantly influences susceptibility to optokinetic illusion.
Article Abstract
Objective: To study the effects of the field-dependent cognitive style on optokinetic illusion.
Method: One hundred military university students were tested with Rod and Frame Test. Fifteen high score subjects and 15 low score subjects were arranged into field-dependent group and field-independent group respectively. Each subject experienced a series of optokinetic step stimulation (5, 10, 15, 20, 30, 40, 60, 80, 100, 120 degrees/s) for 20 s. The latent period and fuzzy estimate magnitude of the illusion were recorded.
Result: The results obtained were as follows: 1) The latent period in the field-dependent group were shorter than that in the field-independent group, and decreased exponentially with the stimulation. The latent period in the field-independent group decreased linearly with stimulus; 2) Between 5-120 degrees/s, the fuzzy magnitude of the two groups regressed to two linear equations, no significant difference was found between the coefficients of two equations, but the intercepts were significantly different.
Conclusion: Cognitive style was found to be an important influencing factor on optokinetic illusion. People with the field-dependent cognitive style were susceptible to optokinetic illusion.

Lifestyle factors and ambient air pollution are linked to dementia and CMDs, yet few studies have investigated their impact on dementia risk in CMDs patients at the same time. The Cox proportional hazards model was used to evaluate the influence of lifestyle and ambient air pollution on the dementia risk of the CMDs population among 438,681 participants in the UK Biobank. It is found that the risk of developing mild cognitive impairment and dementia in the population seems to increase with the increase in the number of CMDs.

Aging inevitably gives rise to many challenges and transitions that can greatly impact our (mental) well-being and quality of life if these are not controlled adequately. Hence, the key to successful aging may not be the absence of these stressors, but the ability to demonstrate resilience against them. The current study set out to explore how resilience and successful aging may intersect by investigating how various resilience capacity-promoting (protective) and resilience capacity-reducing (risk) factors relate to mental well-being and quality of life.

Background: In online mental health communities, the interactions among members can significantly reduce their psychological distress and enhance their mental well-being. The overall quality of support from others varies due to differences in people's capacities to help others. This results in some support seekers' needs being met, while others remain unresolved.

Introduction: Psychological disorders including depression and anxiety are significant public health concerns. A Mediterranean-style dietary pattern (MDP) has been associated with improved mental well-being in observational studies. Evidence of the acute (defined as postprandial to 1 week) effects of an MDP on brain function, mood, cognition and important modulators, including sleep and the gut microbiota is limited.
