Unlike with the typically developing population, non-typically developing individuals, especially those with intellectual disabilities, have usually been recommended to learn and use only one language, despite perhaps coming from bilingual families or living in multilingual environments. This common practice, however, is not backed by empirical…

To address the high-rate, interfering stereotypy of three autistic students, a chained schedule for treating stereotypy was combined with skill-based treatment for challenging behavior. Treatment consisted of progressively widening contingencies to differentially reinforce functional communication, toleration, and accurate task completion with…

Background music with lyrics can be a prevalent distraction in environments where people study or read while music plays. However, such effects on reading comprehension across different language contexts remain insufficiently investigated. Guided by the duplex-mechanism account of auditory distraction and the semantic-interference hypothesis, the…

Forty French gendarmes from the "Gendarmerie Nationale," and 40 laypersons completed two experiments to assess how they make inferences from testimonies. The first experiment targeted how inferences are made when the critical information on which a judgment has to be made is explicitly stated in the testimony or it is implicit and has to…

Individuals with Autism Spectrum Disorder (ASD) are thought to under-rely on prior knowledge in perceptual decision-making. This study examined whether this applies to decisions of attention allocation, of relevance for 'predictive-coding' accounts of ASD. In a visual search task, a salient but task-irrelevant distractor appeared with higher…

The effects of rewards on executive function (EF) reflect bidirectional interactions among motivational and executive systems that vary with age and temperament. However, methodological limitations hinder understanding of the precise influences of incentives on early EF, including the role of reward sensitivity. In this within-subjects study,…

The picture-word interference paradigm (participants name target pictures while ignoring distractor words) is often used to model the planning processes involved in word production. The participants' naming times are delayed in the presence of a distractor (general interference). The size of this effect depends on the relationship between the…

The cognitive advantage (CA) hypothesis claims that multilingualism promotes the development of several basic cognitive capacities. A large number of empirical findings support this hypothesis, but recently there have also been numerous contradictory findings and methodological objections. The present paper extends the investigation of possible…

Dividing attention (DA) between a memory task and a secondary task results in deficits in memory performance across a wide array of memory tasks, but these effects are larger when DA occurs at encoding than at retrieval. Although some research suggests the effects of DA are equal for item and associative memory, thereby suggesting that DA disrupts…

Introduction: The current study examined the extent to which practice amount mediates dual-task interference patterns associated with concurrent performance of a novel speech task and attention-demanding visuomotor task. Method: A Sequential Nonword Repetition Task was used to examine the effect of practice on interference associated with…

Previous studies demonstrated that dual-task impairments are higher in children than in young adults. A previous study systematically assessed the sources of these larger dual-task impairments by identifying age-related differences in capacity limitations during dual-task processing. Capacity limitations in central cognitive processes were present…

Numerous studies from psychology, cognitive science, and neuroscience have generated substantial evidence suggesting that multitasking while doing schoolwork has a significant detrimental effect on student learning and performance. Despite this evidence, attending to multiple streams of information and entertainment while doing homework, writing a…

Different studies indicate that emotions can interfere with the efficacy of inhibitory control. However, understanding this impact requires considering that inhibition is not a unitary construct. Cognitive inhibition is the process responsible for attenuating and resisting the interference of thoughts, representations, and memories that are…

The role of relative salience in processing of hierarchical stimuli in individuals with autism spectrum disorder (ASD) was examined in this study. Participants with ASD and typically developing controls performed a Navon letters task under conditions of global salience, local salience or equal salience of both levels. Results revealed no group…

Prior research has shown that interruptions lead to a variety of performance costs. However, these costs are heterogenous and poorly understood. Under some circumstances, interruptions lead to large decreases in accuracy on the primary task, whereas in others task duration increases, but task accuracy is unaffected. Presently, the underlying cause…
