Collecting data with infants is notoriously difficult. As a result, many of our studies consist of small samples, with only a single measure, in a single age group, at a single time point. With renewed calls for greater academic rigor in data collection practices, using multiple outcome measures in infant research is one way to increase rigor, and, at the same time, enable us to more accurately interpret our data. Here, we illustrate the importance of using multiple measures in psychological research with examples from our own work on rapid threat detection and from the broader infancy literature. First, we describe our initial studies using a single outcome measure, and how this strategy caused us to nearly miss a rich and complex story about attention biases for threat and their development. We demonstrate how using converging measures can help researchers make inferences about infant behavior, and how using additional measures allows us to more deeply examine the mechanisms that drive developmental change. Finally, we provide practical and statistical recommendations for how researchers can use multiple measures in future work.

Social anxiety typically emerges by adolescence and is one of the most common anxiety disorders. Many clinicians and researchers utilize the Screen for Child Anxiety Related Disorders (SCARED) to quantify anxiety symptoms, including social anxiety, throughout childhood and adolescence. The SCARED can be administered to both children and their parents, though reports from each informant tend to only moderately correlate. Here, we investigated parent-child concordance on the SCARED in a sample of adolescents (N = 360, M age = 13.2) using a multitrait multi-method (MTMM) model. Next, in a selected sample of the adolescents, we explored relations among child report, parent report, and latent social anxiety scores with two laboratory tasks known to elicit signs of social anxiety in the presence of unfamiliar peers: a speech task and a "Get to Know You" task. Findings reveal differences in variance of the SCARED accounted for by parent and child report. Parent report of social anxiety is a better predictor of anxiety signs Maureen E. Bowers,

For decades, researchers have been interested in humans’ ability to quickly detect threat-relevant stimuli. Here, we review recent findings from infant research on biased attention to threat and discuss how these data speak to classic assumptions about whether attention biases for threat are normative, whether they change with development, and what factors might contribute to this developmental change. We conclude that although there is some stability in attention biases in infancy, various factors—including temperamental negative affect and maternal anxiety—also contribute to shaping the development of biased attention.

Snakes and spiders are two of the most commonly feared animals worldwide, yet we know very little about the mechanisms by which such fears are acquired. We explored whether negative information about snakes and spiders from parents shapes children's fear beliefs. Study 1 included 27 parents (22 mothers, five fathers) and children (12 female, 15 male, M age = 5.33 years, 18 White, one Hispanic, eight more than one race). Most parents reported having an advanced degree (78%) and an annual household income of above $100,000 (74%). Participants read an animal picture book and then rated their fear toward each animal. Study 2 included 54 parents (44 mothers, eight fathers, two legal guardians) and children (27 female, 27 male, M age = 5.52 years, 30 White, one Hispanic, seven Asian/Pacific Islander, four South Asian/Indian, 12 more than one race). Most parents reported holding an AA/BA degree (28%) or an advanced degree (59%) and reported an annual household income of $60,000-$100,000 (28%) or above $100,000 (59%). In Study 2, half of the parents were primed about how their conversations might shape children's fear prior to reading the book. Across both studies, we found that participants provided more negative than positive information about snakes and spiders and provided less positive (Study 1) and more negative (Study 2) information compared to other animals. Our results highlight the prominence of negative information in conversations about snakes and spiders and suggest that the way parents talk about these animals may shape the development of children's fears.
