Auditory enhancement and the perception of concurrent vowels

Listeners identified both constituents of double vowels created by summing the waveforms of pairs of synthetic vowels with the same duration and fundamental frequency. Accuracy of identification was significantly above chance. Effects of introducing such double vowels by visual or acoustical precursor stimuli were examined. Precursors specified the identity of one of the two constituent vowels. Performance was scored as the accuracy with which the other vowel was identified. Visual precursors were standard English spellings of one member of the vowel pair; acoustical precursors were 1-sec segments of one member of the vowel pair. Neither visual precursors nor contralateral acoustical precursors improved performance over the condition with no precursor. Thus, knowledge of the identity of one of the constituents of a double vowel does not help listeners to identify the other constituent. A significant improvement in performance did occur with ipsilateral acoustical precursors, consistent with earlier demonstrations that frequency components which undergo changes in spectral amplitude achieve enhanced auditory prominence relative to unchanging components. This outcome demonstrates the joint but independent operation of auditory and perceptual processes underlying the ability of listeners to understand speech despite adversely peaked frequency responses in communication channels.     

Cognitive-Behavioral Therapy in the Treatment of Internalizing Disorders in High-Functioning Youth with Autism Spectrum Disorder

Anxiety and depression are often comorbid with Autism Spectrum Disorder (ASD). There is empirical support to suggest that cognitive-behavioral therapy (CBT) is an efficacious treatment for comorbid anxiety disorders in youth with ASD. Modifications to CBT for youths with ASD have been made with emphasis on exposure being a critical component. Few studies have evaluated the efficacy of CBT on symptoms of depression in youths with ASD. Modifications to CBT will be outlined in this review, as will implementation suggestions for the clinician practicing CBT with ASD youth. Limitations of the studies investigating this intervention include small sample sizes, clinician- and parent-report of symptom change but not consistent self-identified change, limited validated tools for assessing change, and lack of long-term follow-up.     

The role of self-compassion during difficult economic times

Background and objectives: The negative effects of the financial crisis of 2007/2008 are still being felt today as seen in the relatively high levels of youth unemployment in many countries. As a result, many young people experience high stress levels when facing an uncertain and precarious job market.

Methods: Participants were 178 undergraduate students (79% female; M_age?=?20.00, SD?=?4.29) who were randomly assigned to read a news article that documented an uncertain financial future with limited job opportunities (the economic stress group), or an article that documented a tour of the Royal Canadian Mint (the control group). The role of self-compassion was explored in its relation to distress.

Results: Correlational and hierarchical regression analyses indicated that, in the economic stress group, self-compassion negatively predicted anxiety above and beyond self-esteem and familial support. In the control group, however, self-compassion did not negatively predict anxiety above and beyond self-esteem and familial support. Additionally, structural equation modeling indicated that self-compassion was directly associated with lower anxiety and indirectly related to anxiety through perceptions of financial threat.

Conclusions: These findings suggest that self-compassion may be an important resource that is associated with less distress during times of economic threat.
