In spring 2020, U.S. schools universally transitioned to online learning due to the COVID-19 pandemic's onset, thus creating a natural experiment for examining adolescents' risk and resilience during an ongoing school crisis response. This longitudinal study used a daily-diary approach to investigate the role of social support in the link between remote learning and psychological well-being across 64 days among a national sample of adolescents (n = 744; 42% Black, 36% White, 22% Other ethnicity/race; 41% boys; 72% eligible for free/reduced-priced lunch; Mage=14.60, SDage=1.71, age-range = 12-17 years). On days when youth attended remote learning, they reported lower daily positive affect, more daily stress, and higher parent social support. There were no significant differences in the effect of remote learning on affect or stress by race or economic status. On days when youth experienced more parent support, they reported lower daily stress and negative affect and higher daily positive affect. On days when youth experienced more peer support, they reported higher daily positive affect. Overall, the study highlights the impact of pandemic-onset remote learning on adolescents' psychological well-being and emphasizes the need for future research on school crisis contingency planning to address these challenges.
Word learning encompasses the understanding of interconnected clusters of words, where the comprehension of one word aids in the learning of another. Semantic networks, which have a long history in cognitive science, are commonly employed to explore these semantic relationships. However, limited research has been conducted on adults’ use of semantically relevant conversations in the field of early childhood education, and there is insufficient information regarding contextual factors influencing the development of semantic networks. The present study investigated the extent to which the use and effectiveness of semantically relevant conversations vary across activity contexts. This study analyzed data from the Home-School Study of Language and Literacy Development (HSLLD) Corpus available in the CHILDES database, focusing on a subset of 62 children. This study utilized four statistical features to describe the structure of semantic networks: short path length, diameter, density, and clustering coefficient. The following findings emerged: (1) Book reading displayed a significantly greater diameter than toy play and mealtime, indicating that there exist specific pairs of concepts or words within its semantic networks that are notably more distant from each other than in the other two activity settings. (2) Toy play exhibited a significantly greater density in comparison to book reading and mealtime, suggesting a higher degree of overlap or interdependence among the concepts within its semantic networks. (3) Book reading demonstrated a significantly greater clustering coefficient compared to toy play and mealtime, signifying the existence of cohesive word communities or groups of words characterized by dense internal connections. (4) Adults’ use of semantically relevant conversations during book reading was positively associated with children’s lexical diversity. © 2023 by the authors.
Semantic distance scoring provides an attractive alternative to other scoring approaches for responses in creative thinking tasks. In addition, evidence in support of semantic distance scoring has increased over the last few years. In one recent approach, it has been proposed to combine multiple semantic spaces to better balance the idiosyncratic influences of each space. Thereby, final semantic distance scores for each response are represented by a composite or factor score. However, semantic spaces are not necessarily equally weighted in mean scores, and the usage of factor scores requires high levels of factor determinacy (i.e., the correlation between estimates and true factor scores). Hence, in this work, we examined the weighting underlying mean scores, mean scores of standardized variables, factor loadings, weights that maximize reliability, and equally effective weights on common verbal creative thinking tasks. Both empirical and simulated factor determinacy, as well as Gilmer-Feldt's composite reliability, were mostly good to excellent (i.e., > .80) across two task types (Alternate Uses and Creative Word Association), eight samples of data, and all weighting approaches. Person-level validity findings were further highly comparable across weighting approaches. Observed nuances and challenges of different weightings and the question of using composites vs. factor scores are thoroughly provided.
In spring 2020, the COVID-19 pandemic thrust nearly 56 million students in the United States into remote education. By fall 2020, states' and school districts' differing public health measures resulted in the adoption of varying COVID-adapted learning modalities (i.e., in-person, remote, and hybrid). Using daily diary data with a nationally representative sample (N = 517, M-age = 14.65 years), we investigated whether adolescents' academic engagement and connectedness to their teachers and classmates differed by COVID-adapted learning modalities. We also assessed whether adolescent connectedness mediated the link between learning modality and academic engagement. Results revealed that academic engagement and connectedness to teachers and classmates were higher for in-person learners than for students in hybrid and remote learning modalities. Moreover, students' connectedness to classmates and teachers explained the relationship between learning modality and academic engagement.
What factors influence predictions of creative performance? Prior work indicates that images can skew predictions in the contexts of learning, memory, and decision making, but little work has devoted attention to the metacognitive effects of images in creative thinking. Metacognitive frameworks indicate that people often base predictions of performance on the subjective ease with which related information comes to mind. The present experiments tested whether the presence of object photographs in the alternate uses task (AUT) inflates predictions of creativity. In Experiments 1-4, participants made ratings about their predictions of creative performance for various objects in the AUT either with or without photographs of the object. Participants provided higher ratings and were faster to make ratings in the image than no-image condition. In Experiment 5, participants actually attempted to generate creative uses for the objects, half of which were accompanied by object photographs. Creativity scores for these responses were lower in the image condition than no-image condition, but participants' retrospective judgments indicated the opposite. These results provide a novel extension of metacognitive work showing that images inflate predictions of performance and fit with prior research showing that images can limit creativity.
Though adults tend to endorse the stereotype that boys are better than girls in math, children tend to favor their own gender or be gender egalitarian. When do individuals start endorsing the traditional stereotype that boys are better? Using two longitudinal U.S. datasets that span 1993 to 2011, we examined three questions: (1) What are the developmental changes in adolescents' gender stereotypes about math abilities from early to late adolescence? (2) Do the developmental changes vary based on gender and race/ethnicity? (3) Are adolescents' stereotypes related to their math motivational beliefs? Finally, (4) do these patterns replicate across two datasets that vary in historical time? Adolescents in grades 8/9 and 11 were asked whether girls or boys are better at math (n's = 1186 and 23,340, 49-53% girls, 30-54% White, 13-60% Black, 1-22% Latinx, and 2% to 4% Asian). Early adolescents were more likely to be gender egalitarian or favor their own gender. By late adolescence, adolescents' stereotypes typically shifted towards the traditional stereotype that boys are better. In terms of race/ethnicity, White and Asian adolescents significantly favored boys, whereas Black and Latinx adolescents were more likely to endorse gender egalitarian beliefs. Adolescents' stereotypes were significantly related to their expectancy beliefs, negatively for girls and positively for boys.
The associative theory posits that creativity relates to people's ability to connect remote associations to form new ideas, based on the structure of their semantic memory. This theory has spurred several recent studies connecting semantic memory structure and associative thinking to creativity, capitalizing on advances in computational methods. To date, however, this research has almost exclusively focused on assessing creativity in the general population (e.g., assessed via divergent thinking tests), with far less work examining the role of associative thinking in eminently-creative individuals across the arts and sciences. Leveraging data collected as part of the Big-C Project-a sample of world-renowned visual artists (VIS) and scientists, and an intelligence-matched comparison group-we tested whether the ability to generate remote word associations differs as a function of creative expertise. Specifically, we used distributional semantic models to calculate the semantic distance of word associations across three conditions: a free association condition and two goal-directed conditions (common association and uncommon association). We found an interaction between domain expertise and association condition: while artists generated more distant associations overall, this effect was driven by substantially more distant responses in the free association condition. Our findings indicate that VIS spontaneously produce more remote associations-potentially due to a more interconnected semantic memory network structure-but that creative expertise is less relevant for producing associations that require goal-directed cognitive search. The findings are interpreted in the context of the ongoing debate on the domain-generality and domain-specificity of creativity.
Peers' negative police encounters may have collateral consequences and shape adolescents' relationship with authority figures, including those in the school context. Due to the expansion of law enforcement in schools (e.g., school resource officers) and nearby neighborhoods, schools include spaces where adolescents witness or learn about their peers' intrusive encounters (e.g., stop-and-frisks) with the police. When peers experience intrusive police encounters, adolescents may feel like their freedoms are infringed upon by law enforcement and subsequently view institutions, including schools, with distrust and cynicism. In turn, adolescents will likely engage in more defiant behaviors to reassert their freedoms and express their cynicism toward institutions. To test these hypotheses, the present study leveraged a large sample of adolescents (N = 2,061) enrolled in classrooms (N = 157) and examined whether classmates' police intrusion predicted adolescents' engagement in school-based defiant behaviors over time. Results suggest that classmates' intrusive police experiences in the fall term predicted higher levels of adolescents' engagement in defiant behaviors at the end of the school year, regardless of adolescents' own history of direct police intrusive encounters. Adolescents' institutional trust partially mediated the longitudinal association between classmates' intrusive police encounters and adolescents' defiant behaviors. Whereas past studies have largely focused on individual experiences of police encounters, the present study uses a developmental lens to understand how the effects of law enforcement-perpetuated intrusion on adolescent development may operate through peer interactions. Implications for legal system policies and practices are discussed.
This study examines how collaborative activity among students and the teacher to investigate disciplinary questions, which we term 'joint exploration', is established and maintained in a secondary mathematics classroom. Although collaborative and active learning is increasingly sought after in mathematics classrooms, studies of instances of joint exploration remain relatively rare. In this study, we use the theoretical perspective of positioning to conceptualize joint exploration as involving the negotiation among participants to position students with epistemic authority and agency. Using a constant comparative method, we use classroom video data of two episodes containing joint exploration and closely analyse the shifts in epistemic positioning within them. We find that shifts in epistemic positioning, especially with respect to students positioning one another with epistemic authority and exercising epistemic agency, help to support continued joint exploration. We also find that the teacher can play an important role in decentring themselves as the epistemic authority. In addition to these findings, this study contributes a distinction in epistemic authority and agency, as we explain how the two concepts are related and involved in establishing and maintaining joint exploration. Dans cette etude, on cherche a comprendre comment l'activite collaborative entre les eleves et l'enseignant pour analyser des questions liees a la discipline, ce que nous appelons << exploration conjointe >>, est etablie et maintenue dans une classe de mathematiques du secondaire. Bien que l'apprentissage collaboratif et actif soit de plus en plus recherche dans les classes de mathematiques, les etudes portant sur les exemples d'exploration conjointe restent relativement rares. Dans cette etude, nous utilisons l'approche theorique du positionnement pour conceptualiser l'exploration conjointe sur la base d'une negociation entre les participants afin de doter les eleves d'une autorite epistemique et d'une capacite d'agir. A l'aide d'une methode comparative soutenue, nous employons des donnees video montrant deux episodes d'exploration conjointe en classe et analysons de pres les changements de positionnement epistemique observes dans ces episodes. Nous constatons que les variations de positionnement epistemique, en particulier en ce qui concerne les eleves qui s'attribuent les uns les autres une autorite epistemique et qui exercent egalement une capacite d'agir epistemique, contribuent a soutenir le maintien de l'exploration conjointe. Nous remarquons egalement que l'enseignant peut jouer un role important en s'eloignant de son role d'autorite epistemique. Au-dela de ces resultats, cette etude etablit une distinction entre l'autorite epistemique et la capacite d'agir, alors que nous expliquons comment les deux concepts sont lies et impliques dans la mise en oe uvre et le maintien de l'exploration conjointe.
Meta-analysts often ask a yes-or-no question: Is there an intervention effect or not? This traditional, all-or-nothing thinking stands in contrast with current best practice in meta-analysis, which calls for a heterogeneity-attuned approach (i.e., focused on the extent to which effects vary across procedures, participant groups, or contexts). This heterogeneity-attuned approach allows researchers to understand where effects are weaker or stronger and reveals mechanisms. The current article builds on a rare opportunity to compare two recent meta-analyses that examined the same literature (growth mindset interventions) but used different methods and reached different conclusions. One meta-analysis used a traditional approach (Macnamara & Burgoyne, 2023), which aggregated effect sizes for each study before combining them and examined moderators one-by-one by splitting the data into small subgroups. The second meta-analysis (Burnette et al., 2023) modeled the variation of effects within studies-across subgroups and outcomes-and applied modern, multilevel metaregression methods. The former concluded that growth mindset effects are biased, but the latter yielded nuanced conclusions consistent with theoretical predictions. We explain why the practices followed by the latter meta-analysis were more in line with best practices for analyzing large and heterogeneous literatures. Further, an exploratory re-analysis of the data showed that applying the modern, heterogeneity-attuned methods from Burnette et al. (2023) to the data set employed by Macnamara and Burgoyne (2023) confirmed Burnette et al.'s conclusions; namely, that there was a meaningful, significant effect of growth mindset in focal (at-risk) groups. This article concludes that heterogeneity-attuned meta-analysis is important both for advancing theory and for avoiding the boom-or-bust cycle that plagues too much of psychological science.
