Evidence accumulation models have enabled strong advances in our understanding of decision-making, yet their application to examining learning has not been common. Using data from participants completing a dynamic random dot-motion direction discrimination task across four days, we characterized alterations in two components of perceptual…

Finding and prioritizing time for professional learning is a persistent challenge for schools and educators. To address that challenge, this workbook guides districts and schools as they develop, vet, implement, and evaluate a plan to increase collaborative learning time for educators. The tools in the workbook can be used to identify and analyze…

When facing many options, we narrow down our focus to very few of them. Although behaviors like this can be a sign of heuristics, they can actually be optimal under limited cognitive resources. Here, we study the problem of how to optimally allocate limited sampling time to multiple options, modeled as accumulators of noisy evidence, to determine…

Detection methods for item preknowledge are often evaluated in simulation studies where models are used to generate the data. To ensure the reliability of such methods, it is crucial that these models are able to accurately represent situations that are encountered in practice. The purpose of this article is to provide a critical analysis of…

English-speaking adults often recruit a "mental timeline" to represent events from left-to-right (LR), but its developmental origins are debated. Here, we test whether preschoolers prefer ordered linear representations of events and whether they prefer culturally conventional directions. English-speaking adults (n = 85) and 3- to…

We propose a method to measure the speed of sound in air using a motion detector. The experiment is based on the principle of a motion detector used to measure distances. This device measures the time of flight of alternating ultrasonic waves between the observer and the target. By assuming a fixed speed of sound, the time of flight can be…

A qualitative study using situational analysis (Clarke, 2005) explored the temporal experiences of 25 lesbian, gay, bisexual, transgender, and queer students with disabilities at a U.S. research university. Drawing upon queer and critical examinations of time, this manuscript details students' experiences navigating and transgressing normative…

The North Dakota University System "2022-2023 Annual Enrollment Report" is an effort to report system wide, duplicated and unduplicated student headcount by combining degree credit, non-degree credit, and non-credit enrollments across the eleven NDUS institutions for an entire academic year. The academic year is reported as preceding…

Background: Choice is a key part of the culture of the United States. Americans believe deeply in the personal and social usefulness of being able to make many choices. Hence, all sorts of efforts have been made to increase students' options, whether by creating many different kinds of schools and colleges, offering a great array of majors and…

Although it has long been known that time is a cue to causation, recent work with adults has demonstrated that causality can also influence the experience of time. In "causal reordering" (Bechlivanidis & Lagnado, 2013, 2016) adults tend to report the causally consistent order of events rather than the correct temporal order. However,…

Education Code section 76002 requires the California Community Colleges Chancellor's Office to prepare and submit a report each year on the number of special part-time and special full-time full-time equivalent students (FTES) claimed by each community college district for the preceding academic year in each of the following class categories: (1)…

University students are often depicted as carefree young adults; however, many students struggle to manage the "normal" stresses of university life and may experience high rates of psychological distress. This study compared a traditional delivery model to a shorter delivery model (i.e., the Southern Cross Model) in terms of students'…

Traffic incidents caused by vehicular crashes, roadway construction, disabled and abandoned vehicles, extreme weather conditions, and planned special events, comprise about half of all traffic congestion. As the duration of traffic incidents increases, it increases the probability of severe congestion, secondary crashes, traveler delay, travel…

In Spring 2020, colleges across the nation swiftly transitioned their operations--including both classes and student support services--to remote delivery on an emergency basis in response to the crisis posed by the COVID-19 pandemic. While prior research has documented that the transition was associated with decrements in student outcomes, there…

How does one assess developmental change when the measures themselves change with development? Most developmental studies of word learning use either looking (infants) or pointing (preschoolers and older). With little empirical evidence of the relationship between the two measures, developmental change is difficult to assess. This paper analyzes…
