In speech perception tasks with ambiguous bottom-up information, lexical processes have been shown to influence listener responses, such as in phoneme categorization tasks (Ganong, 1980). Proponents of interactive theories of speech perception and spoken word recognition assert this influence is a top-down feedback mechanism that can affect…

Money skills are important for students with autism spectrum disorder (ASD) to successfully live independently. A crucial first step is teaching them money identification. The purpose of this study was to examine the efficacy of using TouchMath money (TMM) to teach middle school students with ASD to count money. A multiple probe design across…

Instructors use prompts to assist learners in acquiring skills and then fade those prompts until responding occurs under the appropriate stimulus control conditions. Cengher et al. "Journal of Developmental and Physical Disabilities," 30, 155-173 (2018) reviewed studies that compared two or more different prompt-fading procedures. The…

This article connects the "Theory of Extended Mind" with the use of three-dimensional, physical objects in dance pedagogy. The theory of the extended mind supposes that cognition is an activity that reaches out from the mind to the body and to the environment. In particular, we take up Dewey's pragmatic Instrumentalism as a framework…

Children with autism spectrum disorder (ASD) often lack symbolic play skills. Attribution of pretend properties (APP) is a type of symbolic play in which a child tacts pretend properties of an object (e.g., smelling a toy flower and saying, "It smells like a rose!"). Three Chinese boys (5-6 years of age) with ASD served as participants.…

Background: People with severe-to-profound intellectual disabilities often lack meaningful interactions with others. Communication partners need to be skilled in identifying and responding to often-subtle behaviours. One method of facilitating interaction is the use of sensory-based stimuli. Method: This study measured the impact of sensory-based…

Various theories suggest that human beings differ regarding their susceptibility to environmental stimuli, some of these theories have their origin in the field of developmental psychology. From an evolutionary perspective, it has been assumed that this susceptibility trait follows a normal distribution in the population, with a minority being…

This triple-arm, double-blind, randomized clinical trial investigated the effect of multisession prefrontal transcranial direct current stimulation (tDCS) on social functioning in individuals with autism spectrum disorder (ASD). A total of 105 individuals (age 14-21 years) diagnosed with ASD were randomized into the active-tDCS, sham-tDCS, and…

When people judge the duration of stimuli, judgments are influenced by the physical size of these stimuli. Specifically, people tend to judge the duration of large stimuli longer than the duration of small stimuli. However, some authors (Bottini & Casasanto, 2010; Ma, Yang, & Zhang, 2012) have reported that even implicit size can affect…

Everyone agrees that infants possess general mechanisms for learning about the world, but the existence and operation of more specialized mechanisms is controversial. One mechanism--rule learning--has been proposed as potentially specific to speech, based on findings that 7-month-olds can learn abstract repetition rules from spoken syllables (e.g.…

The Rhythmic Arts Project (TRAP) curriculum integrates visual, tactile, auditory and speech experiences through rhythmic drumming actions to address life skills. We evaluated life skills before and after participation in TRAP in a school-based setting in children with Autism Spectrum Disorders (ASD). Participants were 23 children in grades 6-12 in…

Increasingly, investigators conduct interviews with eyewitnesses from different cultures. The culture in which people have been socialised can impact the way they encode, remember, and report information about their experiences. We examined whether eyewitness memory reports of mock witnesses from collectivistic (sub-Saharan Africa) and…

Social-communication is profoundly impaired among autistic individuals. Difficulties representing others' mental states have been linked to modulations of gaze and speech, which have also been shown to be impaired in autism. Despite these observed impairments in 'real-world' communicative settings, research has mostly focused on lab-based…

A cognitive-energetic account of individual differences in working memory capacity (WMC) and sustained attention performance is proposed suggesting that variation in the voluntary control of the intensity of attention (intrinsic alertness) is critical for the relation between WMC and attention control. Four experiments examining individual…

Motivationally attractive cues can draw in behavior in a phenomenon termed incentive salience. Incentive cue attraction is an important model for animal models of drug seeking and relapse. One question of interest is the extent to which the pursuit of motivationally attractive cues is related to the value of the paired outcome or can become…
