International friendship (i.e., friendship between host-national and international students) is an important area of study for counseling psychologists. Host-national students' engagement with international friendship is associated with cross-cultural learning, cognitive benefits, and a more nuanced understanding of race and stereotyping. Even…

Procedural fidelity refers to the degree to which procedures for an assessment or intervention (i.e., independent variables) are implemented consistent with the prescribed protocols. Procedural fidelity is an important factor in demonstrating the internal validity of an experiment and clinical treatments. Previous reviews evaluating the inclusion…

Neural network dynamics underlying flexible animal behaviors remain elusive. The fruit fly "Drosophila" melanogaster is considered an excellent model in behavioral neuroscience because of its simple neuroanatomical architecture and the availability of various genetic methods. Moreover, "Drosophila" larvae's transparent body…

What is the optimal penalty for errors in infant skill learning? Behavioral analyses indicate that errors are frequent but trivial as infants acquire foundational skills. In learning to walk, for example, falling is commonplace but appears to incur only a negligible penalty. Behavioral data, however, cannot reveal whether a low penalty for falling…

Scientific research relies on funding, and everyone who conducts research must become adept at funding their research. This book explains how to attain the number one source of research funding: grants. Readers will learn how to prepare grant proposals, how and when to interact with funding institutions, how to interpret and respond to peer review…

Objective: The current study aimed to examine whether brief online stress reduction exercises supplemented with sleep improvement strategies would reduce stress, arousal, and sleep difficulties in college students who were not required to use the sleep improvement strategies for participation. Participants: A sample of 114 college student…

Symmetry considerations are important in science, and Group Theory is a theory of symmetry. Classical Measurement Theory is the most used measurement theory in the social and behavioral sciences. In this article, the author uses Matrix Lie (Lee) group theory to formulate a measurement model. Symmetry is defined and illustrated using symmetries of…

Aphasia, language disorder after acquired brain injury, is a chronic condition negatively impacting functional communication and quality of life. More than two million individuals in the United States have aphasia and the most common cause of aphasia is stroke. Further understanding of post-stroke aphasia will ultimately allow for development of…

As the demand for behavior analytic services grows, we can expect to see increased diversity among both people seeking behavior analytic services and people seeking licensure or certification as behavior analysts. We must consider the best methods for teaching multicultural competencies to graduate students while simultaneously accommodating…

This Concise Review is an appraisal of contemporary research on teaching single-case experimental design (SCED) graphical creation published between 2017-2021. Recent work on SCED graphical creation is summarized and areas for future research are highlighted.

To provide context surrounding the history of single-case research and to act as a benchmark for which future changes across the fields and disciplines that use single-case methods may be compared, we conducted this study to serve as an update and extension on the trends and prevalence of single-case research in the peer-reviewed literature. Our…

A new mode of knowledge production, known as the 'organic growth pattern', has emerged within the online learning environment. It exhibits several unique features, such as iterative growth, fuelled by collective intelligence, fuzzy complexity, etc. It is more valuable and adaptable to support knowledge innovation within rapidly changing fields. To…

This note is concerned with the benefits that can result from the use of the maximal reliability and optimal linear combination concepts in educational and psychological research. Within the widely used framework of unidimensional multi-component measuring instruments, it is demonstrated that the linear combination of their components that…

Constructive changes in the practice of investigative interviewing have emerged as a direct result of an unprecedented and robust collaboration between behavioral science researchers and professionals in the field. At the same time, an ever-increasing number of experienced practitioners have shown a willingness to adopt science-based methods in…

The recently proposed "continuous-time latent curve model with structured residuals" (CT-LCM-SR) addresses several challenges associated with longitudinal data analysis in the behavioral sciences. First, it provides information about process trends and dynamics. Second, using the continuous-time framework, the CT-LCM-SR can handle…
