An international cross-sectional investigation on social media, fitspiration content exposure, and related risks during the COVID-19 self-isolation period

With the global COVID-19 pandemic, governments from many countries in the world implemented various restrictions to prevent the SARS-Cov-2 virus's spread, including social distancing measures, quarantine, in-home lockdown, and the closure of services and public spaces. This led to an in-creased use of social media platforms to make people feel more connected, but also to maintain physical activity while self-isolating. Concerns about physical appearance and the desire to keep or reach a muscular and toned ideal body, might have further reinforced the engagement in fitness-related social media activities, like sharing progresses in training achievements or following more fitness contents on popular profiles. To better understand the underlying relation among these factors, the present study investigates 729 responses to the Exercise Addiction Inventory (EAI), the Appearance Anxiety Inventory (AAI), the Self-Compassion Scale (SCS) and their association to social media usage and compares the results cross-culturally in five countries (Spain, Lithuania, United Kingdom, Japan, and Hungary). Findings highlight significant differences between males and females, espe-cially in regard to the time spent online (U = 477.5, p = 0.036). Greater levels of appearance anxiety were associated with the exposure to fitness-related contents on social media. These results strongly confirm the previously highlighted association between fitspiration media and body image anxiety predominantly in females. Clinical implications and future considerations in terms of prevention and treatment in a situation of global emergency are also discussed.

Exploring the Relationship Between Mental Well-Being, Exercise Routines, and the Intake of Image and Performance Enhancing Drugs During the Coronavirus Disease 2019 Pandemic: A Comparison Across Sport Disciplines

Introduction: Physical distancing under the coronavirus disease 2019 (COVID-19) pandemic had a significant impact on lifestyles, including exercise routines. In this study, we examined the relationship between mental health and addictive behaviors, such as excessive exercise and the use of image and performance enhancing drugs (IPEDs) across 12 sport disciplines. Materials and methods: A large cross-sectional sample of the adult population (N = 2,295) was surveyed. The mean age was 33.09 (SD = 11.40). The number of male participants was 668 (30.0%). The use of IPEDs was assessed in conjunction with psychometric measures such as the Exercise Addiction Inventory (EAI) and the Appearance Anxiety Inventory (AAI). The participants were grouped into activity group (AG) and non-activity group (NAG) according to the presence or absence of their exercise habits. The results were compared between these groups, as well as across sport disciplines, while taking into account the relationship between different psychological measures and IPEDs consumption. Results: The frequency of IPEDs use was higher among AG (34.6%) than NAG (14.6%), although AG participants reported less history of addictions (7.1%) than NAG (11.8%). The logistic regression analysis revealed that scores equal to or above cutoff points, in both the EAI and AAI, predicted the IPEDs use. Regarding the differences across the various sport disciplines, those who were involved in practicing Weight Lifting and Cross Fit were found to be more at risk of excessive exercising and more inclined to use a wide range of IPEDs. Conclusions: Although exercise could help to increase well-being and prevent addictions during the COVID-19 pandemic, our results show that those in the AG are particularly vulnerable to excessive IPEDs use. Sport disciplines associated with higher EAI and AAI scores have also shown a higher tendency to excessive IPEDs use. Furthermore, the factor of having above the cutoff scores in EAI or AAI in each sport could indicate larger IPEDs consumption regardless of the discipline. In light of the current findings, it is necessary to better define the "non-excessive" levels of exercise in various sport disciplines and an adequate intake of IPEDs to ensure the safety and well-being of people during a pandemic.

Exercise and Use of Enhancement Drugs at the Time of the COVID-19 Pandemic: A Multicultural Study on Coping Strategies During Self-Isolation and Related Risks

Introduction: Little is known about the impact of restrictive measures during the COVID-19 pandemic on self-image and engagement in exercise and other coping strategies alongside the use of image and performance-enhancing drugs (IPEDs) to boost performance and appearance. Objectives: To assess the role of anxiety about appearance and self-compassion on the practice of physical exercise and use of IPEDs during lockdown. Methods: An international online questionnaire was carried out using the Exercise Addiction Inventory (EAI), the Appearance Anxiety Inventory (AAI), and the Self-Compassion Scale (SCS) in addition to questions on the use of IPEDs. Results: The sample consisted of 3,161 (65% female) adults from Italy (41.1%), Spain (15.7%), the United Kingdom (UK) (12.0%), Lithuania (11.6%), Portugal (10.5%), Japan (5.5%), and Hungary (3.5%). The mean age was 35.05 years (SD = 12.10). Overall, 4.3% of the participants were found to engage in excessive or problematic exercise with peaks registered in the UK (11.0%) and Spain (5.4%). The sample reported the use of a wide range of drugs and medicines to boost image and performance (28%) and maintained use during the lockdown, mostly in Hungary (56.6%), Japan (46.8%), and the UK (33.8%), with 6.4% who started to use a new drug. Significant appearance anxiety levels were found across the sample, with 18.1% in Italy, 16.9% in Japan, and 16.7% in Portugal. Logistic regression models revealed a strong association between physical exercise and IPED use. Anxiety about appearance also significantly increased the probability of using IPEDs. However, self-compassion did not significantly predict such behavior. Anxiety about appearance and self-compassion were non-significant predictors associated with engaging in physical exercise. Discussion and Conclusion: This study identified risks of problematic exercising and appearance anxiety among the general population during the COVID-19 lockdown period across all the participating countries with significant gender differences. Such behaviors were positively associated with the unsupervised use of IPEDs, although no interaction between physical exercise and appearance anxiety was observed. Further considerations are needed to explore the impact of socially restrictive measures among vulnerable groups, and the implementation of more targeted responses.

Lexical Priming in Alzheimer's Disease and Aphasia

Lexical priming was examined in patients with Alzheimer's disease and in aphasic patients. Control participants were divided into young and elderly [cf. Arroyo-Anlló et al.: Eur J Cogn Psychol 2004;16:535-553]. For lexical priming, a word-stem completion task was used. Normal elderly participants had lexical priming scores that were significantly lower than those of young individuals. Analysis of covariance with age and educational level as covariates showed that the control participants, aphasic and Alzheimer patients did not differ significantly on the lexical priming task. Our results suggest that performance in the lexical priming task diminishes with physiological aging, but is not significantly affected by mild or moderate Alzheimer's disease or by fluent or non-fluent aphasia.

Procedural learning of semantic categorization: a study of 110 non-disabled individuals

PURPOSE

This paper describes a cognitive procedural task in order to study procedural learning of semantic categorization. We evaluated age, educational level and gender effects on semantic procedural skill.

METHODS

The procedural task was developed in our laboratory, applying a manual and serial reaction time paradigm to semantic categorization. We investigated this form of procedural learning in 110 non-disabled subjects.

RESULTS

We observed an improvement of semantic categorization reaction times (RTs) over time from practice, even with new verbal material to categorize. Age, educational level and gender did not influence procedural learning of semantic categorization but women performed faster than men. The results suggest that semantic categorization is susceptible to procedural training.

CONCLUSION

The results suggest that semantic categorization is susceptible to procedural training.

[Procedural learning and neurological disorders]

INTRODUCTION AND DEVELOPMENT

We review the current state of learning procedures in six neurological conditions: amnesia, Alzheimer-type dementia, Huntington's disease, Parkinson's disease, progressive supranuclear paralysis and cerebellar pathology. In each condition the conservation or deterioration of different types of ability is specified: motor and percepto-motor abilities were evaluated using different tests such as following a rotating disk or signal, the labyrinth test, percepto-motor adaptation test or tests using paradigms of time of serial reaction; percepto-cognitive abilities evaluated by 'mirror-reading' and cognitive abilities evaluated by the Tower of Hanoi, of Toronto, or of London.

CONCLUSION

Most of the papers published describe conservation of learning procedures in amnesic syndromes, relatively conserved in Alzheimer's disease and relatively deteriorated in Huntington's disease, in progressive supranuclear paralysis and in cerebellar dysfunction.

[Procedural learning in aphasic patients]

OBJECTIVE

This study concerned the procedural learning of semantic categorization.

PATIENTS AND METHODS

The procedure used was a serial reaction time in an group of aphasic patients.

RESULTS

Group of aphasic patients performed slower reaction times with more errors than the controls, but everyone manifested a decreasing reaction time, even during new semantic material categorization.

CONCLUSIONS

Our results showed that the semantic categorization could be facilitated by procedural learning. Furthermore, this study suggest that procedural learning of semantic categorisation is at least relatively independent from cerebral structures usually involved a group of aphasic patients.

[Cerebral evoked potentials and semantic categorization]

INTRODUCTION

Cerebral evoked potentials represent variations in the electrical activity of the nervous system, excited by a sensory stimulus and which are recorded on the surface. They may be classified as endogenous or exogenous. Amongst the late endogenous evoked potentials (EEP) we may emphasize N400 which seems to represent the linguistic management wave, particularly for semantics.

OBJECTIVE

To observe the EEP recorded throughout the process of carrying out a task involving sequential semantic categorization.

PATIENTS AND METHODS

Nine healthy subjects carried out a task based on a paradigm of sequential reaction time (RT), similar to that designed by us in 1994. The data recorded were the RT and EEP at the level of the electrodes Fz, Cz and Pz in five lots of stimuli (in the first four lots the same list of words were repeated and in the fifth and final lot a different, new list appeared).

CONCLUSIONS

It was seen that only N400 varied during the procedure. This variation was related to familiarity with the task. That is to say that the amplitude of N400 was reduced when the same words were repeated and increased when new words appeared for semantic classification. The reduction in parallel, although not significant for RT, allowed the reduction in N400 alone to be followed whilst the task was carried out. It may be the electrophysiological marker of the process of learning semantic categorization.
