People sometimes lie by omitting information. The information lie tellers then report could be entirely truthful. We examined whether the truthful information that lie tellers report in omission lies contains verbal cues indicating that the person is lying. We made a distinction between (i) essential information (events surrounding the omission)…

In topography-based verbal behavior, different antecedent stimuli control different topographies of responding, whereas in selection-based verbal behavior, different antecedent stimuli control the selection of visually distinct stimuli from an array of options. In this article, we point out three variable characteristics of selection-based…

Background: Sustained vowels are important vocal tasks that have been investigated in discriminating voice disorders using acoustic analysis. To date, no study has combined vowel acoustic measures only that evaluate major aspects of the pathological voice signals in voice disorder discrimination. Aims: To investigate the value of vowel acoustic…

In the current study, eight college students were exposed to a successive matching-to-sample (S-MTS) procedure utilizing non-verbal auditory stimuli consisting of common sounds. During emergent relations tests, participants were asked to talk aloud, and their vocal-verbal statements were transcribed and categorized as class-consistent,…

Drawing on recent scholarship integrating usage-based linguistics (UBL) and conversation analysis (CA) in the investigation of second language development, this paper reports on a microanalysis tracing one adult learner's recurring, increasingly frequent, and diverse use of the multiword expression "det er sant" (it/that is true) (DES)…

911 calls reporting the mysterious disappearance of a child may contain information critical to law enforcement. If this information is untruthful, valuable resources can be misdirected and precious time may be lost. Therefore, the current study examined verbal cues of veracity and deception in 911 calls placed by caregivers of missing children.…

External representations powerfully support and augment complex human behavior. When navigating, people often consult external representations to help them find the way to go, but do maps or verbal instructions improve spatial knowledge or support effective wayfinding? Here, we examine spatial knowledge with and without external representations in…

The inclusion of private events in the philosophy of our science is integral to avoid dualism and remain objective rather than making assumptions about an unseen mind. However, the inclusion of behaviors and stimuli which cannot be observed in an analysis poses obvious issues. One established method of studying covert behavior is to examine tasks…

Purpose: The objective of the present study is to investigate nasal and oral vowel production in French-speaking children with cochlear implants (CIs) and children with typical hearing (TH). Vowel nasality relies primarily on acoustic cues that may be less effectively transmitted by the implant. The study investigates how children with CIs manage…

Background: Initiating meaningful moments of interaction with people with profound intellectual disabilities can prove to be difficult for support staff. Exploring the behaviour of support staff that precedes the initiations of behaviour by people with profound intellectual disabilities helps to shed light upon the potential facilitating effects…

The early language environment, especially high-quality, contingent parent-child language interactions, is crucial for a child's language development and later academic success. In this secondary analysis study, 89 parent-child dyads were randomly assigned to either the Music Together® (music) or play date (control) classes. Children were 9- to…

Background: Children with Tourette syndrome (TS) have historically experienced problems in academic and social settings, yet their language and communication abilities have not been extensively researched. Aims: This scoping review maps the literature on the oral language and social communication abilities of children with TS in order to describe…

The purpose of the study was to evaluate the effects of tact and match-to-sample instructions on the increase and maintenance of intraverbal responses to subcategorical questions (i.e., naming multiple items in a subcategory of a category). Three Chinese children on the autism spectrum (2 boys, 1 girl, aged 6-8 years old) participated in this…

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…

Throughout healthcare, including education, the need for voicing of concern by speaking up is a globally recognized issue that has come to the fore in the last ten years. There has been a rapid growth in the number of review articles on the topic. To prevent diffusion of knowledge and support future research it is necessary to gather the existing…
