Context effects, where a characteristic of an upper-level unit or cluster (e.g., a country) affects outcomes and relationships at a lower level (e.g., that of the individual), are a primary object of sociological inquiry. In recent years, sociologists have increasingly analyzed such effects using quantitative multilevel modeling. Our review of multilevel studies in leading sociology journals shows that most assume the effects of lower-level control variables to be invariant across clusters, an assumption that is often implausible. Comparing mixed-effects (random-intercept and slope) models, cluster-robust pooled OLS, and two-step approaches, we find that erroneously assuming invariant coefficients reduces the precision of estimated context effects. Semi-formal reasoning and Monte Carlo simulations indicate that loss of precision is largest when there is pronounced cross-cluster heterogeneity in the magnitude of coefficients, when there are marked compositional differences among clusters, and when the number of clusters is small. Although these findings suggest that practitioners should fit more flexible models, illustrative analyses of European Social Survey data indicate that maximally flexible mixed-effects models do not perform well in real-life settings. We discuss the need to balance parsimony and flexibility, and we demonstrate the encouraging performance of one prominent approach for reducing model complexity.

Musicians display a variety of auditory perceptual benefits relative to people with little or no musical training; these benefits are collectively referred to as the “musician advantage.” Importantly, musicians consistently outperform nonmusicians for tasks relating to pitch, but there are mixed reports as to musicians outperforming nonmusicians for timbre-related tasks. Due to their experience manipulating the timbre of their instrument or voice in performance, we hypothesized that musicians would be more sensitive to acoustic context effects stemming from the spectral changes in timbre across a musical context passage (played by a string quintet then filtered) and a target instrument sound (French horn or tenor saxophone; Experiment 1). Additionally, we investigated the role of a musician’s primary instrument of instruction by recruiting French horn and tenor saxophone players to also complete this task (Experiment 2). Consistent with the musician advantage literature, musicians exhibited superior pitch discrimination to nonmusicians. Contrary to our main hypothesis, there was no difference between musicians and nonmusicians in how spectral context effects shaped instrument sound categorization. Thus, musicians may only outperform nonmusicians for some auditory skills relevant to music (e.g., pitch perception) but not others (e.g., timbre perception via spectral differences).

Research suggests that sensorimotor difficulties in autism could be reduced by providing individuals with explicit contextual information. To test this, we examined autistic visuomotor control during a virtual racquetball task, in which participants hit normal and unexpectedly-bouncy balls using a handheld controller. The probability of facing each type of ball was varied unpredictably over time. However, during cued trials, participants received explicit information about the likelihood of facing each uncertain outcome. When compared to neurotypical controls, autistic individuals displayed poorer task performance, atypical gaze profiles, and more restricted swing kinematics. These visuomotor patterns were not significantly affected by contextual cues, indicating that autistic people exhibit underlying differences in how prior information and environmental uncertainty are dynamically modulated during movement tasks.

The use of context to facilitate the processing of words is recognized as a hallmark of skilled reading. This capability is also hypothesized to change with older age because of cognitive changes across the lifespan. However, research investigating this issue using eye movements or event-related potentials (ERPs) has produced conflicting findings. Specifically, whereas eye-movement studies report larger context effects for older than younger adults, ERP findings suggest that context effects are diminished or delayed for older readers. Crucially, these contrary findings may reflect methodological differences, including use of unnatural sentence displays in ERP research. To address these limitations, we used a coregistration technique to record eye movements (EMs) and fixation-related potentials (FRPs) simultaneously while 44 young adults (18–30 years) and 30 older adults (65+ years) read sentences containing a target word that was strongly or weakly predicted by prior context. Eye-movement analyses were conducted over all data (full EM dataset) and only data matching FRPs. FRPs were analysed to capture early and later components 70–900 ms following fixation-onset on target words. Both eye-movement datasets and early FRPs showed main effects of age group and context, while the full EM dataset and later FRPs revealed larger context effects for older adults. We argue that, by using coregistration methods to address limitations of earlier ERP research, our experiment provides compelling complementary evidence from eye movements and FRPs that older adults rely more on context to integrate words during reading.

The paper examines the role of context in reading unpointed Hebrew, demonstrating the changing nature of reliance on context during the course of reading acquisition. We analyze the reading-aloud of sentences with heterographic-homographic ambiguity, aiming to shed light on the development of ambiguity resolution processes in typically developing schoolaged and adult populations. 171 Hebrew-speaking children and adolescents in seven age/schooling groups (beginning and end of second grade, third, fourth, seventh, and eleventh grade), and a group of adults, participated in the study. Using homographic garden-path and non-Garden-path sentences, we demonstrate the cumulative effect of context as well as processes of monitoring cum reanalysis. Two hypotheses are borne out in the present research: First, context effect is inherent to reading; it is present throughout all age/grade groups, becoming more efficient with age/grade level. Second, monitoring and reanalysis lag far behind context effects, appearing only as age and reading experience increase.

Speech perception, like all perception, takes place in context. Recognition of a given speech sound is influenced by the acoustic properties of surrounding sounds. When the spectral composition of earlier (context) sounds (e.g., a sentence with more energy at lower third formant [F 3 ] frequencies) differs from that of a later (target) sound (e.g., consonant with intermediate F 3 onset frequency), the auditory system magnifies this difference, biasing target categorization (e.g., towards higher-F 3 -onset /d/). Historically, these studies used filters to force context stimuli to possess certain spectral compositions. Recently, these effects were produced using unfiltered context sounds that already possessed the desired spectral compositions (Stilp & Assgari, 2019 , Attention, Perception, & Psychophysics, 81 , 2037–2052). Here, this natural signal statistics approach is extended to consonant categorization (/g/–/d/). Context sentences were either unfiltered (already possessing the desired spectral composition) or filtered (to imbue specific spectral characteristics). Long-term spectral characteristics of unfiltered contexts were poor predictors of shifts in consonant categorization, but short-term characteristics (last 475 ms) were excellent predictors. This diverges from vowel data, where long-term and shorter-term intervals (last 1,000 ms) were equally strong predictors. Thus, time scale plays a critical role in how listeners attune to signal statistics in the acoustic environment.

This study investigates the use of structural and discourse contextual cues in the interpretation of third-person pronouns by children and adolescents with autism and their neurotypical peers. Results show that referent-biasing contextual information influences pronominal interpretation and modulates looking patterns in both groups compared to a context-neutral condition. These results go against the predictions of Weak Central Coherence and the notion that pragmatics in general is impaired in ASD, since the ASD group was able to use details in discourse context to influence the pronominal interpretation process. However, although discourse context influenced looking patterns in both groups, the groups nevertheless diverged in the nature of these patterns, suggesting that behavioral differences may emerge in more complicated discourse tasks.

Purpose: Conceptual models of complex health problems are useful when designing targeted clinical interventions and focused research studies. Understanding and studying patient adherence often involves interplay among many factors that influence whether a patient successfully follows recommendations or completes a therapy program. Functional frameworks serve to arrange these factors visually, increasing interpretability and allowing for empirical testing of relationships among concepts. The purpose of this article is to integrate relevant factors from the literature into a comprehensive framework that describes adherence to dysphagia treatment. Method: Using peer-reviewed, published guidelines regarding conceptual model construction, the authors created a list of potential factors that influence patient adherence to dysphagia-related treatment recommendations. During model construction, following extensive review of the literature and existing theories that have been applied in other areas of health care, factors were identified and grouped into conceptually similar domains (clusters). Clusters were arranged into larger categories that emerged during model optimization. Ultimately, two models were created: one that illustrates the interrelated factors of patient adherence and another that illustrates a subset of modifiable risk factors that a clinical speech-language pathologist may influence when developing a dysphagia treatment plan. Results: Three general categories from 14 factors emerged based on relationships between factors and aspects of patient care--health factors, individual patient factors, and contextual factors. A second model consisting of modifiable risk factors included access, treatment type, patient perceptions, self-efficacy, health literacy, support factors, and provider bias. Conclusions: This conceptual model allows clinicians and researchers to identify and explore the mechanisms driving adherence. Continual refinements of this model should be made as future studies uncover how the interconnectedness of factors affects adherence in dysphagia management. The models we have presented here are ready for clinical application and should also serve researchers as they generate hypotheses and design targeted research questions.

Understanding which factors can impact rater judgments in assessments is important to ensure quality ratings. One such factor is whether prior performance information (PPI) about learners influences subsequent decision making. The information can be acquired directly, when the rater sees the same learner, or different learners over multiple performances, or indirectly, when the rater is provided with external information about the same learner prior to rating a performance (i.e., learner handover). The purpose of this narrative review was to summarize and highlight key concepts from multiple disciplines regarding the influence of PPI on subsequent ratings, discuss implications for assessment and provide a common conceptualization to inform research. Key findings include (a) assimilation (rater judgments are biased towards the PPI) occurs with indirect PPI and contrast (rater judgments are biased away from the PPI) with direct PPI; (b) negative PPI appears to have a greater effect than positive PPI; (c) when viewing multiple performances, context effects of indirect PPI appear to diminish over time; and (d) context effects may occur with any level of target performance. Furthermore, some raters are not susceptible to context effects, but it is unclear what factors are predictive. Rater expertise and training do not consistently reduce effects. Making raters more accountable, providing specific standards and reducing rater cognitive load may reduce context effects. Theoretical explanations for these findings will be discussed.
