This paper explores the issue of whether assimilation time has any bearing on the performance of students. Assimilation time is defined as the number of times during the week that a class meets. This study examined whether students would perform better in a 50-minute class that met three days a week versus a 75-minute class that met just two days…

The ACT has been used as an assessment instrument for student admission to many colleges and universities in the United States. The fate of many students depends on their ability to make an acceptable score in order to enroll in college credit courses and avoid remediation. Even though the ACT is not the only criteria for admission to college, it…

We tested the hypothesis that training a parent in wheelchair-user and caregiver wheelchair skills would improve the child's wheelchair skills. We studied an 11-year-old girl with spina bifida and her mother. The mother received 4 training sessions averaging 42.5 minutes per session, over a period of 3 weeks. The total pre-training and, 4 weeks…

The current study examines the Strong Interest Inventory's (SII) ability to measure vocational interests and better understand how it predicts concurrent undergraduate academic majors. Although much literature exists concerning vocational interest measurement, no published study has utilized all scales on the SII to predict concurrent academic…

A sparse mask that persists beyond the duration of a target can reduce its visibility, a phenomenon called "object substitution masking". Y. Jiang and M. M. Chun (2001a) found an asymmetric pattern of substitution masking such that a mask on the peripheral side of the target caused stronger substitution masking than on the central side.…

A field-based, soil methods, and instrumentation course was developed to expose graduate students to numerous strategies for measuring soil parameters. Given the northern latitude of North Dakota State University and the rapid onset of winter, this course met once per week for the first 8 weeks of the fall semester and centered on the field as a…

The purpose of this study is to examine pre-service teachers' attitudes to computers. This study extends the technology acceptance model (TAM) framework by adding subjective norm, facilitating conditions, and technological complexity as external variables. Results show that the TAM and subjective norm, facilitating conditions, and technological…

In his article, "An Alternative to Null-Hypothesis Significance Tests," Killeen (2005) urged the discipline to abandon the practice of "p[subscript obs]"-based null hypothesis testing and to quantify the signal-to-noise characteristics of experimental outcomes with replication probabilities. He described the coefficient that he…

It is well known that languages differ in how they encode motion. Languages such as English use verbs that communicate the manner of motion (e.g., "slide", "skip"), while languages such as Greek regularly encode motion paths in verbs (e.g., "enter", "ascend"). Here we ask how such cross-linguistic encoding…

The choice of pedagogy in statistics should take advantage of the quantitative capabilities and scientific background of the students. In this article, we propose a model for a statistics course that assumes student competency in calculus and a broadening knowledge in biology. We illustrate our methods and practices through examples from the…

Computerized lessons that reflect stimulus equivalence principles were used to teach college students concepts related to inferential statistics and hypothesis decision making. Lesson 1 taught participants concepts related to inferential statistics, and Lesson 2 taught them to base hypothesis decisions on a scientific hypothesis and the direction…

According to classical theories, automatic processes are autonomous and independent of higher level cognitive influence. In contrast, the authors propose that automatic processing depends on attentional sensitization of task-congruent processing pathways. In 3 experiments, the authors tested this hypothesis with a modified masked semantic priming…

This paper proposes an argument framework for the teaching of null hypothesis statistical testing and its application in support of research. Elements of the Toulmin (1958) model of argument are used to illustrate the use of p values and Type I and Type II error rates in support of claims about statistical parameters and subject matter research…

In this article, we present a study that tests the Interface Hypothesis (Sorace and Filiaci, 2006) at the syntax-pragmatics interface and its possible extension to the syntax-morphology interface in two groups of first language (L1) speakers of Shipibo with different levels of formal instruction in Spanish as a second language (L2). Shipibo is a…

The aim of the current study is to validate the invariance of major profile patterns derived from multidimensional scaling (MDS) by bootstrapping. Profile Analysis via Multidimensional Scaling (PAMS) was employed to obtain profiles and bootstrapping was used to construct the sampling distributions of the profile coordinates and the empirical…
