This study examined if listener behavior and responding by exclusion would emerge after training 3 participants with autism to tact stimuli. Tacts for 2 of 3 stimuli were directly trained using discrete trial training methodology and were followed by an auditory-visual discrimination probe in which auditory-visual discrimination by naming (i.e.,…

Clinically, social interaction, including gaze-triggered attention, has been reported to be impaired in autism spectrum disorder (ASD), but psychological studies have generally shown intact gaze-triggered attention in ASD. These studies typically examined gaze-triggered attention under simple environmental conditions. In real life, however, the…

Differences in motivation during adolescence relative to childhood and adulthood in autism was tested in a cross-sectional study. 156 Typically developing individuals and 79 individuals with autism ages 10-30 years of age completed a go/nogo task with social and non-social cues. To assess age effects, linear and quadratic models were used.…

The findings are evidence that persons with ASD benefit more than typically developing (TD) persons from spatial framing cues in focusing their attention on a visual target. Participants were administered a forced-choice task to assess visual filtering. A target stimulus was presented on a screen and flanker stimuli were presented simultaneously…

Typically developing adults with low and high Autism Spectrum Quotient (AQ) scores made rapid social evaluations of neutral faces when these were primed by briefly presented emotional faces. High AQ participants rated neutral faces as more threatening than low AQ participants, regardless of the prime condition. Both groups rated target neutral…

Auditory stream segregation allows us to organize our sound environment, by focusing on specific information and ignoring what is unimportant. One previous study reported difficulty in stream segregation ability in children with Asperger syndrome. In order to investigate this question further, we used an interleaved melody recognition task with…

Two studies were conducted to investigate how high-functioning children with autism use different linguistic cues in sentence comprehension. Two types of linguistic cues were investigated: word order and morphosyntactic cues. The results show that children with autism can use both types of cues in sentence comprehension. However, compared to…

Individuals with autism often exhibit atypical levels of attention to eyes. High support need and minimally verbal individuals with autism have typically received less attention in research. This study explored a preference based computer game to include the less-studied individuals with autism in their own school environment. Four high support…

In autism spectrum disorder (ASD), atypical integration of visual depth cues may be due to flattened perceptual priors or selective fusion. The current study attempts to disentangle these explanations by psychophysically assessing within-modality integration of ordinal (occlusion) and metric (disparity) depth cues while accounting for sensitivity…

We first demonstrated analytic processing in ASD under conditions in which integral processing seems mandatory in TD observers, a pattern that is often taken to indicate a local default processing in ASD. However, this processing bias does not inevitably come at the price of impaired integration skills. Indeed, examining the same group of…

Establishing whether implicit responses to emotional cues are intact in autism spectrum disorder (ASD) is fundamental to ascertaining why their emotional understanding is compromised. We used a temporal bisection task to assess for responsiveness to face and wildlife images that varied in emotional salience. There were no significant differences…

In this research, the emotion recognition abilities of children with autism spectrum disorder and typically developing children were compared. When facial expressions and situational cues of emotion were congruent, accuracy in recognizing emotions was good for both children with autism spectrum disorder and typically developing children. When…

We conducted two separate but related single-case studies using alternating treatment designs to investigate the effects of two single-component reading interventions: question development and anaphoric cueing. In each study, we compared a typical intervention approach (Study 1, question development; Study 2, anaphoric cueing) with an alternate…

Findings from research investigating goal-directed intention understanding in children with autism spectrum disorders (ASD) have been equivocal, in part because of the varying methodologies used across studies. This study compares both object-oriented and social-communicatively cued goal-directed intention understanding in children with ASD and…

The present study evaluated the ability of males with fragile X syndrome (FXS), nonsyndromic autism spectrum disorder (ASD), or typical development to learn new words by using as a cue to the intended referent an emotional reaction indicating a successful (excitement) or unsuccessful (disappointment) search for a novel object. Performance for all…
