As the foundation of pleasantness and aesthetic valence of an object, an optimal level of evoked arousal or, in more recent research, of information load, has been proposed. According to discrepancy theory, this evoked effect is modulated by the object's deviation from the current adaptation level (AL). The AL is built up and updated by pooling recent stimulation. A model based on these concepts is proposed here, and it is illustrated by results of empirical studies by the author's students. For everyday objects such as cars and ladies' clothes, rated beauty was related by a U-shaped function to rated modernity. Minimal beauty occurred for intermediate modernity. For ladies' clothes, this minimum was situated higher on the modernity scale for females and extraverts. As modernity can be seen as the amount of deviation from the AL which represents the usual, this shift could be explained by faster upward adjustment of the AL. In contrast, for paintings the relation between modernity and beauty was inversely U-shaped. This could be due to paintings intrinsically carrying more information than other objects, as indicated by ratings of hard-to-access, with which rated beauty had an inverse U-shaped relation. In a factor-analytic study of preference for 42 paintings four orthogonal factors were extracted, interpreted as High and Low modernity, and High and Low information content. This could yield a rudimentary empirical typology of art.</p>","PeriodicalId":20598,"journal":{"name":"Progress in brain research","volume":"287 ","pages":"45-70"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141889953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, studies have employed physical activity as an intervention to help with cognition in aging individuals. Despite this, the underlying mechanism (or mechanisms) by which benefits occur remain unclear. We investigated whether improved trainability for individuals engaged in sport or fitness training might underlie such benefits. Specifically, we assessed motor skill performance and learning rates in young adult runners, baseball players, and \"control\" individuals who did not regularly engage in sport or exercise using an implicit motor sequence learning task. Better initial performance on the task was seen for both the runner group and the baseball group but no benefits were seen for the baseball/runner groups for rates of improvement on the task. This was the case for both non-specific learning (or general motor skill learning-learning not associated with specific sequences of responses) and for sequence-specific learning (or improvement on repeated sequences of responses that participants were not aware of). This pattern may mean that either engagement in sport/physical activity results in improvements that are transferable beyond the context of the sport/training activity or that engagement in sport/exercise may relate to initial differences in the motor competence of an individual. Further work could beneficially investigate learning in more directly cognitive-related tasks and consolidation/improvement of performance over more prolonged time periods. Importantly, assessment of a fitness/sport intervention on performance and learning rates may provide a better context for some of the benefits reported in cross-sectional investigations of the effects of sport/fitness on cognition and aid in determining which differences are due to engaging in exercise and which differences affect the tendency for such engagement.</p>","PeriodicalId":20598,"journal":{"name":"Progress in brain research","volume":"283 ","pages":"305-325"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140306627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, there is limited research on the association between regular physical activity and memory abilities during young adulthood. The Individual Alpha Peak Frequency (IAPF) contributes to various cognitive abilities and also appears to be sensitive to physical activity. Consequently, the IAPF has the potential to underlie the association between physical activity and verbal memory. We examined the direct relation of physical activity and verbal memory, and the potential indirect relation via IAPF in young adults. Regular physical activity was assessed via accelerometry on seven consecutive days in 115 participants (N=115, 48% female) aged 18-35 years (M=24.1, SD=3.8). In addition, verbal memory performance was assessed using an immediate and delayed free-recall task. Brain activity during rest was recorded with EEG, and IAPF was extracted for mediation analyses. Path analysis revealed pronounced sex differences in the association between physical activity, IAPF, and verbal memory performance. Exclusively in female participants, higher vigorous physical activity levels were associated with better recall performance. In contrast, no association of physical activity and memory was found in male participants. However, being more physically active was related to a higher IAPF exclusively in male participants. Physical activity shows differential associations between IAPF and verbal memory in male and female participants.

This study aimed to investigate associations between daily moderate-to-vigorous physical activity (MVPA), sedentary time, and neurocognitive functioning during adolescence. Fifty-seven participants (37% female) between the ages of 13 and 17 years wore an accelerometer on their non-dominant wrist for approximately 1 week to quantify daily MVPA and sedentary time prior to completing a flanker task to elicit P300 amplitude at a laboratory visit. Results indicated that daily MVPA and sedentary time exhibited unique, significant associations with P300 amplitude in opposing directions: increased daily MVPA was correlated with larger P300 amplitudes, while increased daily sedentary time was linked to reduced P300 amplitudes. Notably, these associations remained significant even after adjusting for age, sex, and BMI-for-age percentile. These findings underscore the independent influence of daily MVPA and sedentary time on neurocognitive functioning during adolescence.

Some epidemiological studies suggest a potential protective effect of coffee consumption against schizophrenia, whereas others fail to establish a significant correlation. Clinical investigations highlight the complexity of caffeine's influence, with varied effects on symptom severity and cognitive function observed among schizophrenia patients. Notably, caffeine may exacerbate positive symptoms while alleviating negative symptoms and cognitive deficits in this population. However, limitations such as small sample sizes and reliance on self-reported data hinder the generalizability of these findings. Furthermore, genetic factors, prenatal exposure, and substance abuse contribute to the complexity of the relationship between caffeine and schizophrenia. Studies indicate that individuals with a genetic predisposition to schizophrenia may be more vulnerable to the effects of caffeine, while prenatal exposure to caffeine may elevate the risk of schizophrenia in offspring. Additionally, substance abuse, including high caffeine and nicotine consumption, is prevalent among individuals with schizophrenia, exacerbating symptom severity. Future research directions include addressing methodological limitations, such as small sample sizes and reliance on self-reported data, and exploring the effects of caffeine on schizophrenia using larger, more diverse cohorts and controlled methodologies.
