The application of growth curve modeling for the analysis of diachronic corpora

This paper introduces growth curve modeling for the analysis of language change in corpus linguistics. In addition to describing growth curve modeling, which is a regression-based method for studying the dynamics of a set of variables measured over time, we demonstrate the technique through an analysis of the relative frequencies of words that are increasing or decreasing over time in a multi-billion word diachronic corpus of Twitter. This analysis finds that increasing words tend to follow a trajectory similar to the s-curve of language change, whereas decreasing words tend to follow a decelerated trajectory, thereby showing how growth curve modeling can be used to uncover and describe underlying patterns of language change in diachronic corpora.

Abstract Objective Media consumption over time is suggested to be a significant contributor to how people develop their self-perceptions of aging (SPA); however, this association has only been investigated with cross-sectional methodologies. The current study used growth curve modeling to examine the influence of 10 years of television, newspaper, radio, and book consumption on positive and negative dimensions of SPA. Method Growth curve modeling on four waves of data from the German Aging Survey (N =2,969), a population-based representative survey of adults aged 40 to 95, was used to examine the longitudinal associations between media consumption and SPA trajectories. Results Across ten years, more television intake (B= -0.58, 95% CI [-0.94, -0.21]) was associated with lower perceptions of continuous growth. Inversely, greater book (B= 0.10, 95% CI [0.06, 0.13]) and radio (B= 0.52, 95% CI [0.29, 0.74]) consumption was significantly linked to higher perceptions of continuous growth. In parallel, more television (B= 0.88, 95% CI [0.52, 1.25]) and newspaper consumption (B= 0.46, 95% CI [0.04, 0.88]) was associated with higher perceptions of physical decline, while greater radio (B= -0.40, 95% CI [-0.64, -0.16]) and book (B= -0.05, 95% CI [-0.09, -0.00]) consumption was associated with lower perceptions of physical decline. Discussion This study provides longitudinal evidence that the type of media consumed over time is linked to people’s SPA. Not all types of media intake are negative as radio and book consumption was associated with better SPA across time. Age group differences were investigated and are discussed in the supplemental materials.

Over Time

Researchers often collect longitudinal data to model change over time in a phenomenon of interest. Inevitably, there will be some variation across individuals in specific time intervals between assessments. In this simulation study of growth curve modeling, we investigate how ignoring individual differences in time points when modeling change over time relates to convergence and admissibility of solutions, bias in estimates of parameters, efficiency, power to detect change over time, and Type I error rate. We manipulated magnitude of the individual differences in assessment times, distribution of assessment times, magnitude of change over time, number of time points, and sample size. In contrast to the correct analysis, ignoring individual differences in time points frequently led to inadmissible solutions, especially with few time points and small samples, regardless of the specific magnitude of individual differences that were ignored. Mean intercept and slope were generally estimated without bias. Ignoring individual differences in time points sometimes yielded overestimated intercept and slope variances and underestimated intercept–slope covariance and residual variance. Parameter efficiency as well as power and Type I error rates for the linear slope were unaffected by the type of analysis.

Abstract This article illustrates how speech-language pathologists (SLPs) can use language sampling and growth curve modeling (GCM) to examine the language growth rates of English Language Learners. GCM data on language samples provides SLPs with powerful, new tools to evaluate actual progress over time instead of relying on single, static measurement endpoints to determine typical development.

The Impact ◽

Over Time

Although the impact of religion on behavior is robust and well-examined in many areas, the role spirituality plays in changes in drug use over time has received relatively little attention. Using a life-course theoretical framework, this relationship is examined through growth curve modeling techniques. Specifically, multilevel analyses are estimated testing within-person relationships between substance use desistance and spirituality. The Pathways to Desistance longitudinal data are analyzed and leading criminological predictors are included, to determine if spirituality has a unique impact on substance use net of these criminological factors, and if these impacts vary across gender. Results from these analyses suggest that the impact of spirituality on desistance varies by gender, with spirituality significantly increasing the odds of desistance from marijuana use for females, but not males.
