Previous research in the U.S. using predominantly English-speaking, low-risk samples suggests that firstborns tend to show better early cognitive and school readiness skills than later-born children. In contrast, while later-born men have lower full-time earnings, they are not less likely to work full-time [Figure 1]. In high-risk or language minority families, however, being later-born had a non-significant or even positive direct effect on child outcomes. On the one hand, early exposure to a minority language presents children with the opportunity to become proficient bilinguals and reap the cognitive and social benefits of bilingualism (Bialystok, 2009). LS and I-MC reviewed and edited the manuscript. All authors contributed to the article and approved the submitted version. (2b) Does the mediation pathway via children's engagement in home learning activities vary by children's exposure to cumulative risks and language minority experiences at home (see Figure 1C)? Unlike low-risk or English-speaking families, where there was a firstborn advantage in child outcomes, there was no difference between firstborn and later-born or even a later-born advantage in high-risk or language minority families. Mothers were on average 27.5 years of age (SD = 6.36, range = 1550) at the birth of the target child, and 50.2% of them were working at baseline. One possible explanation for these differences is that cognitive ability varies systematically by birth order. Lesson 1 04 types of data - SlideShare doi: 10.1016/j.ecresq.2021.05.006, Rodriguez, E. T., and Tamis-LeMonda, C. S. (2011). Parent-child quality time: does birth order matter? The data are quantitative because they consist of counts or measurements. doi: 10.1111/j.1467-8624.2006.00911.x, Ricciardi, C., Manfra, L., Hartman, S., Bleiker, C., Dineheart, L., and Winsler, A. All covariates were associated with at least one of the key variables (i.e., child outcomes and the mediator). The cumulative risk variable, language minority index, and demographic covariates were controlled in these models. Finally, in low-risk or English-speaking families, birth order had a direct effect favoring firstborns on child outcomes, above and beyond children's engagement in home learning activities. Cumulative risk and early cognitive development: a comparison of statistical risk models. doi: 10.1093/jae/ejq013, Whiteman, S. D., McHale, S. M., and Soli, A. The families received 1 point for the presence of each of the following four risk factors: (1) Poverty, indicated by whether or not the annual income of the family was below the federal poverty line in the year of data collection (0-no/no risk, 1-yes/at risk); (2) Single-mother household, indicated by whether the father was living in the household (0-yes/no risk, 1-no/at risk); (3) Low maternal education, indicated by whether mothers had high school or lower level of education (0-higher than high school/no risk, 1- high school or lower/at risk); and (4) Maternal depression. Unlike the classic birth order theories, which view siblings as competitors for family resources, the social learning theories consider siblings as socializers and role models who enrich children's learning experiences via positive sibling relationships and sibling interactions such as play and teaching (Bandura, 1977; Whiteman et al., 2011). Future research should explore whether birth order shows differential effects on children's school readiness skills in English and in the home language. Given that cumulative risks and language minority experiences may reduce or even reverse the firstborn advantage in children's home learning experiences, these contextual factors may also moderate the effect of birth order on early development. What is the relationship between Commerce and economics? What was the date of sameul de champlians marriage? Personality is another factor that is posited to vary by birth order, a proposition that has been particularly difficult to assess in a compelling way due to the paucity of large datasets containing information on individual personality. (2) Mothers' English proficiency, measured at baseline (i.e., 9-month wave) by 4 self-reported items about how well the mother was able to understand, speak, read, and write in English (1-not well at all, 4-very well).

You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Although prior work has documented a firstborn advantage in children's development of early cognitive and school readiness skills (e.g., Barreto et al., 2017; Lehmann et al., 2018), how and in which context(s) birth order plays a role are not yet fully understood. Sci. (3) Mothers' foreign-born status was measured at baseline (i.e., 9-month wave). (2020). Step-by-step explanation: Consider the provided information. In language minority families, older siblings can be more acculturated and have better English skills than their parents and may therefore provide quality support to their younger siblings' language and literacy skills in English (Farver et al., 2013). School readiness skills at age four predict academic achievement through 5th grade. Answers to these questions will provide a more accurate picture of the role of birth order in early childhood development and reveal the complex interrelationships among birth order, home environment, and broader ecological context. We used birth order as the key predictor and children's concurrent developmental outcomes (i.e., cognitive skills at 24 months or literacy and math skills at preschool) as the dependent variables, respectively. The value of quantitative Variables can be determined by counting or measuring something. Building on Strength: Language and Literacy in Latino Families and Communities. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, continuous, or nieither, and indicate the level of measurement for the data. Am. The conditional direct effect indicated a marginal, firstborn advantage (p = 0.064) in English-speaking families, but a later-born advantage in language minority families (see Table 2). Compared to later-born children, firstborn children engaged in home learning activities more frequently, which in turn predicted higher levels of literacy and math skills. The math assessment included 44 items focusing on number sense, counting, operations, geometry, pattern understanding, and measurement (Snow et al., 2007). Hurtado-Ortiz, M. T., and Gauvain, M. (2007). Categorical variables take category or label values, and place an individual into one of several groups. In the ECLS-B dataset, scale scores were calculated using the Item Response Theory (IRT) methods. A reciprocal and dynamic development model for the effects of siblings on children's theory of mind. The current study examined the extent to which the effect of birth order was mediated by home learning environment and moderated by children's exposure to cumulative risks and language minority experiences. Q. Person. What is Nominal Data? Definition, Characteristics, Examples - CareerFoundry Discrete vs Continuous Data: The Key Differences Explained - CareerFoundry They sought to explain an observed negative correlation between family income and family size: if child quality is a normal good, as income rises the family demands higher-quality children at the cost of lower family size.1. A family received 1 if the mother was born outside of the United States and received 0 if the mother was native born. Consistent with our earlier findings on educational attainment but in contrast to the previous work in the literature, we found strong birth order effects on IQ that are present when we look within families. A host of potential explanations has been proposed across several academic disciplines. However, the total effect of birth order was marginally moderated by cumulative risks [b (SE) = 0.53 (0.28), 95% CI = (0.02, 1.08), p = 0.061; see Model 1a, Table 3] and significantly moderated by language minority index [b (SE) = 1.23 (0.29), 95% CI = (0.67, 1.80), p < 0.001; see Model 2a, Table 3]. In line with the bioecological model, which emphasizes the contextual influences on family dynamics (Bronfenbrenner and Morris, 2006), our findings suggested that the firstborn advantage was more evident in low-risk or English-speaking families than in high-risk or language minority families. Another important thing to know, is to figure out the nature of the data we need to analyse. (a) presents the proposed moderation model for Research Question 1b, in which birth order served as the key predictor, and cumulative risks and language minority risks served as the moderators in separate models. What specific section of the world do cannibals do not live? Simple, right? doi: 10.1037/a0028766, Gregory, E. (2001). Child Dev. Once again, the magnitudes are quite large. J. Hum. (2005).

Using data from the American Time Use Survey, I find that a first-born child receives 20-30 more minutes of quality time each day with his or her parent than a second-born child of the same age from a similar family. At baseline (9 months), 51% of children were male, and 83.6% were singletons. doi: 10.1002/per.2285, Bridges, K., and Hoff, E. (2014). Classic birth order theories, including the resource dilution theory and the confluence theory, primarily focus on the distribution of family resources. These relate to changes in the womb environment or maternal immune system that occur over successive births. Both are important for gaining different kinds of knowledge. Child Lang. Pediatr. Finally, the (moderated) mediation models were based on cross-sectional data, which preclude any conclusion on causality. At preschool (48 months), there was a firstborn advantage in children's literacy [b (SE) = 1.34 (0.35), 95% CI = (2.03, 0.65), p < 0.001] and math [b (SE) = 0.66 (0.32), 95% CI = (1.29, 0.03), p = 0.040; see Table 2] skills in the whole sample. Perhaps later-born children experienced dilution in other aspects of their home learning environment, such as quality time with parents (Price, 2008) and parental language input (Hoff, 2006). doi: 10.1016/j.dr.2005.11.002, Hoff, E. (2018). We first examined the overall effect of birth order on children's developmental outcomes. 47, 52625281. Early Childhood Res. When collecting and analyzing data, quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings. Child Dev. There are two major scales for categorical variables: Nominal variables have categories with no distinct or defined order. The IRT scale scores were generated to estimate the number of items children would have answered correctly if they had received the full set of BSID-II mental scale items (possible range of 0178). This has led researchers to study factors that relate to within-family differences in children's outcomes. How social contexts support and shape language development. However, women are more likely to quit smoking during their first pregnancy than during later ones, and firstborns are more likely to be breastfed. The variable is continuous because it is not countable The volume of cola in a can is 10.6 oz. Studies using the National Longitudinal Survey of Youth 1979 (NLSY79) have found that firstborn children outperformed later-born children in cognitive assessments at ages 03 years, after controlling for characteristics of the child and family (Heiland, 2009; Lehmann et al., 2018). The supportive role of older siblings may be more salient in high-risk or language minority families where parents face financial, cultural, or language obstacles to offering rich home learning environment for their children. This translates into approximately a 2 percent difference in annual earnings in adulthood. doi: 10.3368/jhr.51.3.0913-5920R, Peyre, H., Bernard, J. Y., Hoertel, N., Forhan, A., Charles, M.-A., De Agostini, M., et al. There is strong evidence of substantial differences by birth order across a range of outcomes. Inclusion in an NLM database does not imply endorsement of, or agreement with, the contents by NLM or the National Institutes of Health. New Evidence on the Impacts of Birth Order | NBER For families where English was not the primary language, the assessment was conducted in the home language either by a bilingual interviewer or via the assistance of an interpreter. In my earliest work on the topic, Paul Devereux, Kjell Salvanes, and I took advantage of the Norwegian administrative dataset and set out to better understand this theoretical quantity-quality tradeoff.2 It became clear that child "quality" was not a constant within a family children within families were quite different, despite the model assumptions to the contrary. Appl. Section 1.1: Introduction to the Practice of Statistics Trajectories of the home learning environment across the first 5 years: associations with children's vocabulary and literacy skills at prekindergarten. doi: 10.1177/0739986307299584, Isungset, M. A., Lillehagen, M., and Ugreninov, E. (2020). Birth order is often believed to have a profound and lasting effect on psychological development. In low-risk or English-speaking families, firstborn children showed better literacy and math skills at preschool than later-born children, after controlling for children's engagement in home learning activities. We know that family matters children from higher socioeconomic status families do better in school, get more education, and earn more. Three key findings have emerged. We next examined whether children's engagement in home learning activities mediated the effect of birth order on child outcomes (see Figure 1B). Stanton-Chapman, T. L., Chapman, D. A., Kaiser, A. P., and Hancock, T. B. doi: 10.1016/j.intell.2017.09.006, Bayley, N. (1993). First, the firstborn advantage in early cognitive and school readiness outcomes was primarily observed in children from low-risk or English-speaking families. Cogn. For example: gender favorite color Birth order as a quantitative expression of date of birth. OB. Table 2. Birth order as a quantitative expression of date of birth. Firstborns are also more likely to be overweight and obese. Ethnic group differences in early head start parents' parenting beliefs and practices and links to children's early cognitive development. Compared to their peers, children from high-risk or language minority families tend to have fewer opportunities to engage in high-quality learning activities, due to financial hardship, limited human capital, and/or language barriers (Raikes et al., 2006; Rodriguez and Tamis-LeMonda, 2011). Perspect. We expected to observe a smaller firstborn advantage or even a later-born advantage in high-risk or language minority families than in low-risk or English-speaking families. Other studies have suggested a firstborn advantage in important precursors of literacy development, including children's vocabulary and grammatical skills (Hoff-Ginsberg, 1998; Berglund et al., 2005; Hoff, 2006) and vocabulary growth rate (Zambrana et al., 2012) during toddlerhood. In the economics literature, personality traits are often referred to as non-cognitive abilities and denote traits that can be distinguished from intelligence.6 To measure "personality" (or non-cognitive skills), we use the outcome of a standardized psychological evaluation, conducted by a certified psychologist, that is performed on all Swedish men between the ages of 18 and 20 when they enlist in the military, and which is strongly related to success in the labor market. Quantitative or Qualitative - Choosing & Using Sources: A Guide to Chapter 1 Flashcards | Quizlet What years of time was the separate but equal doctrine the law of the land in the US? Strategic parenting, birth order, and school performance. However, in high-risk or language minority families, later-born children showed similar or even higher levels of skills than firstborns. published a paper in American Psychologist entitled "Resolving the Debate Over Birth Order, Family Size, and Intelligence" that referred to the apparent relationship between birth order and IQ as a "methodological illusion. Sisters and brothers as language and literacy teachers: synergy between siblings playing and working together. Black served as a member of President Obama's Council of Economic Advisers, August 2015January 2017. Table 2. In contrast, there was no group difference in high-risk families, and a later-born advantage (0.23 SD) in language minority families. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Impact of gender, maternal education, and birth order on the development of language comprehension: a longitudinal study from 18 to 36 months of age. Number of siblings and intellectual development: the resource dilution explanation. Quantitative vs. Qualitative The basics Typically, a variable can describe either a quantitative or qualitative characteristic of an individual. Alternatively, there is evidence that parents tend to have lower academic expectations for their later-born children (Kim, 2020) and use less strict disciplinary strategies with their later-born children (Hotz and Pantano, 2015), both of which may have been related to lower developmental outcomes of the later-born children. Rev. We expected both the direct effect of being later-born (i.e., path c') and the indirect effect via home learning activities (i.e., path a) to be less negative or even positive in high-risk or language minority families than in low-risk or English-speaking families. Additionally, the current study was the first one showing that the effect of birth order varied by children's home language environment. This type of classification can be important to know in order to choose the correct type of statistical analysis. These findings underscore the complex associations between birth order and early development in diverse ecological contexts. The mental scale consisted of 33 items designed to assess 2-year-olds' early cognitive and language skills, including memory, expressive and receptive vocabulary, reasoning and problem solving, and concept attainment (Andreassen and Fletcher, 2007). Tamis-LeMonda et al., 2019). Written informed consent to participate in this study was provided by the participants' legal guardian/next of kin. For instance, in families of low socioeconomic or immigration backgrounds where parents experience financial hardship or language barriers, older siblings may take more responsibilities in teaching later-born children the host language, engaging them in learning activities, and bridging the home and school cultures (Hurtado-Ortiz and Gauvain, 2007; Obied, 2009; Farver et al., 2013). As shown in Table 2, children's engagement in home learning activities mediated the effect of birth order on children's cognitive skills at 24 months in the whole sample [Unconditional indirect effect: b (SE) = 0.32 (0.07), 95% CI = (0.46, 0.18), p < 0.001]. Additionally, it is beneficial to have information on multiple children from the same family so that birth order effects can be estimated from within-family differences in child outcomes; otherwise, birth order effects will be conflated with other effects that vary systematically with birth order, such as cohort effects. Many statistics, such as mean and standard deviation, do not make sense to compute with qualitative variables. Childhood inputs, especially in the first years of life, are considered crucial for skill formation.9 Firstborn children have the full attention of parents, but as families grow the family environment is diluted and parental resources become scarcer.10 In contrast, parents are more experienced and tend to have higher incomes when raising later-born children. Sociol. Later-born children have lower IQs, on average, and these differences are quite large. While economists have been interested in understanding human capital development for many decades, compelling economic research on birth order is more recent and has largely resulted from improved availability of data. These differences in home learning environment fully explained the firstborn advantage on cognitive skills at ages 03 years (Lehmann et al., 2018). Is the month ordinal or nominal variable? - Cross Validated Differential effects of factors influencing cognitive development at the age of 5-to-6 years. What Are Qualitative and Quantitative Pregnancy Tests Number of citizens of a country. Analyses were performed in Stata 16.1. Indeed, we found that birth order could explain a large fraction of the family size differential in children's educational outcomes. 35, 234248. Methodology Report. J. Postsecondary education among Mexican American youth: contributions of parents, siblings, acculturation, and generational status. Few studies have directly examined the association between birth order and early literacy skills. 2nd Edn. Consistent with previous literature (Raikes et al., 2006; Peyre et al., 2016), these findings confirmed a dilution of parents' interpersonal investments for later-born children in low-risk or English-speaking families. We used Chi-square tests to examine whether the conditional effects of birth order significantly differed between low-risk and high-risk families. Children who did not pass the English screening were either routed to the Spanish version of the literacy and math assessments or did not receive these assessments if they spoke a language other than Spanish and English. Prior to arriving at the University of Texas, she was an economist at the Federal Reserve Bank of New York and a professor in the Department of Economics at UCLA. It is qualitative, as it describes an attribute or quality of the subject, namely the birth month. NCES 2007-084. To examine Research Question 2b, we evaluated the moderated mediation models to understand the extent to which the direct and indirect effects of birth order on child outcomes varied by cumulative risks and language minority index. 2. (2015). A CES-D score of 15 or higher indicated severe depression (0-no severe depression/no risk, 1-severe depression/at risk). Hispanic J. Behav. Birth order and schooling: theory and evidence from twelve sub-saharan countries. (2006). Quantitative vs. Qualitative Data | Following Data doi: 10.1177/014662167700100306, Raikes, H., Pan, B. Children's cognitive skills at 24 months and school readiness skills at preschool were the dependent variables in separate models. Bayley Scales of Infant Development. Although language minority index marginally moderated the indirect effect [b (SE) = 0.11 (0.07), 95% CI = (0.02, 0.25), p = 0.098; see Model 6c, Table 3], the differences in the magnitude of indirect effect between English-speaking and language minority families did not reach the level of significance (see Chi2 tests in Table 2). In subsequent work, Devereux, Salvanes, and I examined the effect of birth order on IQ scores.3. doi: 10.1177/02711214040240040401, Suskind, D. L., Leung, C. Y., Webber, R. J., Hundertmark, A. C., Leffel, K. R., Suskind, E., et al. RL and I-MC contributed in data analysis. Social Learning Theory. Specifically, the conditional indirect effect favored firstborns for children from low-risk or English-speaking families but was non-significant for children from high-risk or language minority families (see Table 2). Vocabulary competence in first-and second born siblings of the same chronological age. Communicative skills in relation to gender, birth order, childcare and socioeconomic status in 18-month-old children. Qualitative means you can't, and it's not numerical (think quality - categorical data instead). These findings suggested that birth order might affect child development in ways beyond home learning activities. The language minority index was the sum score of the three factors, ranging from 0 to 3, calculated at each wave; the higher the index, the more likely a minority language was used at home. Given the small proportion of children (1.37%) who received the assessments in Spanish, only data from the English-assessed children were analyzed. For example, based on evolutionary psychology, Frank J. Sulloway suggests that firstborns have an advantage in following the status quo, while later-borns by having incentives to engage in investments aimed at differentiating themselves become more sociable and unconventional in order to attract parental resources.12. The resource dilution theory posits that a family's human capital (e.g., parental attention, quality time with parents), physical (e.g., books, toys), and financial resources are distributed among siblings (Blake, 1981). She was a co-editor of The Journal of Human Resources, 200512, and editor-in-chief from 201215. Child Care Health Dev. While there was a firstborn advantage in English-speaking families, in language minority families, being later-born positively predicted children's cognitive skills at 24 months and marginally predicted literacy skills at preschool. Preschool book-sharing and oral storytelling experiences in ethnically diverse, low-income families. However, in high-risk families or language minority families, later-born children showed equivalent or marginally (p = 0.082) better skills compared to firstborns (see Table 2).
