Just Let Me Sleep in: Identifying and Treating Delayed Sleep Phase Disorder in Adolescents

Individuals with delayed sleep phase disorder (DSPD) are unable to naturally fall asleep and awake at conventional times; for this reason, DSPD is often mistaken for insomnia. However, unlike many patients with insomnia, those with DSPD struggle to get up at appropriate times. DSPD is associated with school refusal, academic difficulties, and lower employment rate. DSPD in youth has prevalence as high as 16%, and is often comorbid with other psychiatric disorders. Treatments include appropriate light exposure during the day, melatonin use, developing an evening routine that minimizes arousal-increasing activities, and gradually shifting sleep-wake times toward more functional ones.

Vowel sounds in words affect mental construal and shift preferences for targets

A long tradition in sound symbolism describes a host of sound-meaning linkages, or associations between individual speech sounds and concepts or object properties. Might sound symbolism extend beyond sound-meaning relationships to linkages between sounds and modes of thinking? Integrating sound symbolism with construal level theory, we investigate whether vowel sounds influence the mental level at which people represent and evaluate targets. We propose that back vowels evoke abstract, high-level construal, while front vowels induce concrete, low-level construal. Two initial studies link front vowels to the use of greater visual and conceptual precision, consistent with a construal account. Three subsequent studies explore construal-dependent tradeoffs as a function of vowel sound contained in the target's name. Evaluation of objects named with back vowels was driven by their high- over low-level features; front vowels reduced or reversed this differentiation. Thus, subtle linguistic cues appear capable of influencing the very nature of mental representation.

Private Speech and Executive Functioning among High-Functioning Children with Autistic Spectrum Disorders

Private speech used by high-functioning children with autistic spectrum disorders (ASD) (n = 33) during two executive functioning tasks was compared to that of typically developing children (n = 28), and children with ADHD (n = 21). Children with ASD were as likely as others to talk to themselves and their speech was similarly relevant and likely to appear in moments of task difficulty. Unlike others, children with ASD were more likely to get items correct when they were talking than when they were silent. Group differences in performance were observed when children were silent but not when children were talking. Findings suggest that autistic children talk to themselves in relevant ways during problem-solving and that such speech is helpful in normalizing their executive performance relative to controls.
