Purpose: Working memory (WM) deficits are implicated in various communication disorders, including stuttering. The reading span test (RST) measures WM capacity with the dual task of reading sentences aloud and remembering target words. This study demonstrates a difference in strategy between people who stutter (PWS) and people who do not stutter…

As children transition from the early to later grades of elementary school, they become increasingly skilled at employing a variety of techniques -- such as rehearsal and organizational strategies -- for remembering information. Developmental changes in strategy use have been well documented, but little is known about the extent to which these…

Executive functions (EFs) are key abilities that allow us to control our thoughts and actions. Research suggests that two EFs, inhibitory control (IC) and working memory (WM), emerge around 9 months. Little is known about IC earlier in infancy and whether basic attentional processes form the "building blocks" of emerging IC. These…

Purpose: Of the three currently recognized variants of primary progressive aphasia, behavioral differentiation between the nonfluent/agrammatic (nfvPPA) and logopenic (lvPPA) variants is particularly difficult. The challenge includes uncertainty regarding diagnosis of apraxia of speech, which is subsumed within criteria for variant classification.…

Purpose: Humans have a near-automatic tendency to entrain their motor actions to rhythms in the environment. Entrainment has been hypothesized to play an important role in processing naturalistic stimuli, such as speech and music, which have intrinsically rhythmic properties. Here, we studied two facets of entraining one's rhythmic motor actions…

Purpose: This research aimed to identify reliable tasks discriminating French-speaking adolescents with developmental language disorder (DLD) from their peers with typical language (TL) and to assess which linguistic domains represent areas of particular weakness in DLD. Unlike English, morphosyntax has not been identified as a special area of…

The present study investigates the time course of acoustic cue integration in the processing of the Korean three-way laryngeal stop contrast by native Korean listeners and English second language (L2) learners of Korean. As such, this study seeks to understand how native listeners and L2 learners weight and integrate fine-grained acoustic…

Within the context of complex cognitive processing and educational interventions, Woolfolk (2016) makes reference to problem solving acquisition, problem solving retention, and problem solving transfer. In each of the aforementioned types of problem solving activities, problem identification and problem representation (reflecting procedural…

This study investigates the relationships among working memory (WM), syntactic parsing ability (SP), and L2 reading performance across varying proficiency levels. A cohort of 120 L1-Persian EFL learners was categorized into beginner, intermediate, and advanced proficiency groups based on their IELTS scores. Participants completed a reading span…

Within the same learning context, learners' outcomes in terms of oral fluency vary greatly. This study tracked the relative contributions that first language (L1) and initial second language (L2) fluency skill and working memory (WM) made to L2 fluency development. We assessed the performance of French-speaking Grade 6 learners' (n = 47, mean age:…

This study investigated developmental differences in metacognitive monitoring and control in younger (5- to 6-year-old) and older (8- to 10-year-old) children's prospective memory (PM). Metacognitive monitoring was assessed by asking the children to judge their performance before (prediction) and after (postdiction) performing a resource-demanding…

Individual differences in reading skill have frequently been related to variability in working memory capacity; however, it is unclear what drives this relation. The present study investigated two attentional control mechanisms that may contribute to this relation: proactive control and online filtering. To examine how the neural mechanisms of…

The cognitive processes involved in route retracing are not well known. This study aims to highlight them in an elderly population in which contradictory results have been obtained, certain studies showing specific difficulties for route retracing, others not. Thirty-nine elderly subjects performed a route-learning task (forward-backward) in a…

Outstanding long-term face recognition of suspects is a hallmark of the exceptionally skilled police 'super-recognisers' (SRs). Yet, research investigating SR's memory for faces mainly employed brief retention intervals. Therefore, in Experiment 1, 597 participants (121 SRs) viewed 10 target videos and attempted identification of targets from 10…

Although self-report questionnaires are widely used, researchers debate whether responses to these types of questionnaires are valid representations of the respondent's actual thoughts and beliefs. In order to provide more insight into the quality of questionnaire data, we aimed to gain an understanding of the processes that impact the completion…
