The PSID is a nationally representative, longitudinal study, with respondents surveyed annually from 1968 to 1997, and biennially thereafter up to the present. 2022 Aug 12;10:966989. doi: 10.3389/fpubh.2022.966989. << This site needs JavaScript to work properly. Challenges to this assumption include the possibility that season itself is predictive of cognitive performance. (2005) found that time outdoors moderates the relationship between weather and affective and cognitive outcomes, which suggests that behavior (i.e., going outside, rather than general abstract satisfaction with positive weather conditions) is the linchpin in the causal process. Clipboard, Search History, and several other advanced features are temporarily unavailable. ), particularly in children (Ludyga et al. Falbe, Jennifer, Bernard Rosner, Walter C. Willett, Kendrin R. Sonneville, Frank B. Hu, and Alison E. Field. The results showed that participation in passive leisure activities, such reading, talking on the telephone and watching TV/listening to the radio, is more frequent among older adults (P = 0.000). Yet other experimental research has found that even very short exposures (i.e., minutes, not hours) to high-intensity media can depress the executive functioning in children (Lillard and Peterson 2011), negatively mirroring related RCT study findings in physical activity. These observations are nevertheless preliminary and provisional, as researchers have tended to focus on the effects of physical behavior on cognition later in the life course (i.e., older adults) rather than in childhood (Prakash et al. The extant evidence illustrates that activity (and inactivity) may be related both to physical changes in the brain itself, along with cognitive improvements that can positively affect test performance through numerous channelsincluding those that relate to behavior (e.g., ability to focus) rather than intellectual skill per se. This suggests that even halving the time spent engaging in sedentary behavior or consuming electronic media could manifest in significant math gains. sharing sensitive information, make sure youre on a federal endobj 2014 Jul 23;9:24616. doi: 10.3402/qhw.v9.24616. The effects of sedentary behavior and screen time are particularly meaningful, given that by the 2007 wave, the adolescents in our data spent over 2.5 hours each day performing these passive leisure activities. Meta-analyses of research on the effects of acute exercise intervention suggest a positive effect on executive functioning (i.e., skills that allow for planning, multitasking, self-control, etc. We find evidence that physical and outdoor activity positively influence math performance, while sedentary behavior and screen time exhibit the opposite effect. endobj That is, the brain seems to work harder in certain seasons than it does in others to exhibit stable performance, with the only difference being in energy expenditure. /Length 7 0 R That is, parents may deliberately modify their childs behavior because they are not performing as well in school in a way that is reflected in cognitive tests.

Active ageing and quality of life: factors associated with participation in leisure activities among institutionalized older adults, with and without dementia. While more immediate effects are difficult to estimate, extant work tends to show that childhood exposure to these compounds is associated with reduced academic achievement and cognitive functioning, as well as with accelerated decline later in the life course (Clifford et al. Liddle, 1975, Cole and Bayfield, 1993 laid the foundations for this research field It may be the case that population-level estimates (i.e., average treatment effects) are lower than what we find here, if, for example, there are declining marginal returns to going outside for outdoor-oriented children, or adaptations to staying indoors for their indoor-oriented counterparts. /BitsPerComponent 8 * p < .05 ** p < .01 *** p < .001 (two-tailed tests). Standard OLS estimates (pooled across waves) do evince significant, negative relationships between sedentary behavior, television, total screen time, and math scores, but with noticeably smaller coefficients. Here, we use multiple imputation (MI) to handle missing cases, which involves an iterative process where observed data are used to predict missing values multiple times, resulting in a pre-specified number of imputed datasets that are then combined to obtain optimal parameter estimates (McKnight et al. Physical activity lowers blood pressure , which is one of the major contributing factors to cardiovascular events. RECREATION, PASSIVE: Recreation that involves existing natural resources and has a minimal impact. RECREATION, PASSIVE means low intensity recreation activities which have limited noise and light impacts and are minimally disruptive to the natural environment. For the purposes of this title, A sedentary or inactive lifestyle. eCollection 2023. ! Boys may thus reach a saturation point after which each additional unit of electronic media consumption no longer appreciably affects performance. 9 0 obj The .gov means its official. 13 0 obj There is also the related question of what cognition as it is customarily rendered in the social sciences signifies. TABLE 3 Table 3. Erickson, Kirk I., Charles H. Hillman, and Arthur F. Kramer. We find that weighting our data do not affect our estimates. Conceptually, we intuit that short- and medium-run changes in sunlight result in consequent reductions or increases in specific forms of leisure activity over the same time period, which then may have short- and medium-run cognitive effects. There are also other more clinically significant sun-related factors that work in the opposite direction, and would bias our estimates downward. The contribution of the smartphone use to reducing depressive symptoms of Chinese older adults: The mediating effect of social participation. Forests are a natural environment often used for such activities as jogging, hiking, dog walking, mountain biking, or horse riding. /Height 42 HT5T t^c=sSS3=#Ss=S3T48T$& According to some studies, the First, fewer children were eligible to take the reading tests because of different age restrictions. 83 The negative effect of sedentary behavior is less substantial, but still accounts for a reduction of about a fifth of a standard deviation with each additional hour. Though we match sunlight data to the single time diary day, we recognize that these discrete daily averages will usually reflect the time of year they take place in. Benefits such as: improving of cardiovascular health helping a person manage his or her weight lowering calories and cholesterol reducing blood pressure strengthening bond or relationship with other people Conceptually, we do not necessarily see this as a violation of the exclusion restriction because in order to get the benefits of sunlight on cognitive performance via the vitamin D pathway, children do still need to go outside and expose their skin to the sun, as even conventional window glass blocks most ultraviolet rays. If higher-SES children are watching National Geographic and their peers are watching daytime talk shows, one might expect a qualitatively different effect. While some work does offer experimental evidence of the effects of select activities using randomized control trials (RCT)for example, Loprinzi and Kane (2015)it is difficult to infer how routinized behaviors affect outcomes of interest solely based on interventions among carefully targeted respondent populations. One possibility in explaining the differences in effect sizes (or whether behaviors are significantly predictive) stratified by race or sex is the presence of a threshold effect, whereby the marginal consumption of a specific behavior becomes either more or less impactful past a certain point. Establishing the real-world significance and construct validity of cognition as it is commonly measured in aptitude tests is less straightforward than it may seem. We follow the best practices suggested by Graham, Olchowski, and Gilreath (2007) and conservatively use 150 imputations. Despite some evidence of a modest convergence in baseline readiness between 1998 and 2010, differences in aptitude between the richest and poorest children have increased by over a third since 1970s-born cohorts and are currently about twice as large as the black-white achievement gap (Reardon and Portilla 2015). A full table of our time use variables and their stratified descriptive statistics across the three waves is located in the online appendix (appendix table S1). The first two represent the most obvious potential sources of bias. More recently, the theory of concerted cultivation has been developed as an extension of this work to describe how the child-rearing practices of parents and time uses of children systematically differ by race and social class. "(($#$% '+++,.3332-3333333333 * By exploiting the plausibly exogenous variation in weather on the day of measured activity, we can deliver estimates of how more active and passive forms of leisurewhich are particularly sensitive to weather and sunlightcontribute to shaping cognitive assessment over time. Ludyga, Sebastian, Markus Gerber, Serge Brand, Edith Holsboer-Trachsler, and Uwe Phse. We highlight relevant systematic differences in time use among families in our data along with other factors that may contribute to some of the patterns found in our stratified results, and that may also relate to achievement gaps among children more generally. Outdoor recreational activities are increasing worldwide and occur at high frequency especially close to cities. For instance, there could in theory be some character trait that prompts a simultaneous migration to the Sunbelt and an outsized growth in cognition, which would bias our estimates upward. Specifications that were not bounded by lag time restrictions produced substantively similar results, but with smaller coefficients and greater precision, consistent with the growth in sample size and reduced signal after including cases where testing substantially lags or precedes treatment. 2005). Yet these cognitive improvements may be attributable merely to the timing of the test further along in the school year in the second wave, and the substantial accumulation of knowledge children exhibit by virtue of the additive gains they experience as the school year progresses (Fitzpatrick, Grissmer, and Hastedt 2011). The Author(s) 2018. Leisure time activity is often positioned as a key factor in child development, yet we know relatively little about the causal significance of various specific activities or the magnitude of their effects. For each of our time use variables, coefficients are about five to six times as large for the children of non-college-educated mothers compared to their peers, and the null results for the latter are likely at least partly due to more modest first-stage associations, which are near or under commonly proposed weak-instrument thresholds. Because executive function seems especially sensitive to interventions in activity, this suggests that test performance could be affected by, for instance, impulse inhibition more so than improvements in working memory or reaction time. The collection of data used in this study was partly supported by the National Institutes of Health under grant number R01-HD069609 and the National Science Foundation under award number 1157698. We found no noticeable difference in results by excising homework time and confining the measure to the length of the school day alone. Strategies that decrease sedentary time and promote physical activity in its place may have a particularly robust impact on confronting these pernicious inequalities of achievement. /Length 9 0 R As the catchment and reservoir are the first and foremost barriers to protect drinking water quality, these ecological impacts may have a considerable influence on water quality.
