The Relationship Between Executive Function and Functional Mobility in Subacute Stroke Patients
No full textAbstract
Date Presented 3/30/2017
This study explores the relationship between screenings of executive function and measures of functional mobility in subacute stroke patients. Preliminary findings suggest that some functional mobility measures have greater associations with cognitive measures than others.

Actions speak louder than words: comparing automatic imitation and verbal command
No full textAutomatic imitation – copying observed actions without intention – is known to occur, not only in neurological patients and those with developmental disorders, but also in healthy, typically-developing adults and children. Previous research has shown that a variety of actions are automatically imitated, and that automatic imitation promotes social affiliation and rapport. We assessed the power of automatic imitation by comparing it with the strength of the tendency to obey verbal commands. In a Stroop interference paradigm, the stimuli were compatible, incompatible and neutral compounds of hand postures and verbal commands. When imitative responses were required, the impact of irrelevant action images on responding to words was greater than the effect of irrelevant words on responding to actions. Control group performance showed that this asymmetry was not due to modality effects or differential salience of action and word stimuli. These results indicate that automatic imitation was more powerful than verbal command
How Well Do Product Labels Indicate the Presence of PFAS in Consumer Items Used by Children and Adolescents?
No full textPFAS are persistent
and toxic chemicals used in many commercial
and industrial applications that are often added to consumer products,
including those used by children and adolescents, to impart water
and stain resistance. Since product labels rarely list chemical additives,
including PFAS, we evaluated whether other information on product
labels can be used by consumers to select products without PFAS. We
selected 93 items marketed to or often used by children and adolescents
across three product types (furnishings, apparel, bedding) and five
labeling groups representing different combinations of water and/or
stain resistance and “green” (including “nontoxic”)
assurances. We screened all products for total fluorine (F) and analyzed
solvent extracts from a subset (n = 61) for 36 targeted
PFAS and from a smaller subset (n = 30) for perfluoroalkyl
acids (PFAAs) generated by precursor oxidation using the total oxidizable
precursor (TOP) assay. Products advertised as water- and/or stain-resistant
had more frequent detections and higher concentrations of total F
than those without such claims, and targeted PFAS were detected only
in products labeled as water- and/or stain-resistant. Concentrations
of PFAAs generated by precursor oxidation using the TOP assay often
exceeded pre-oxidation concentrations, suggesting that PFAA precursors
contribute to solvent-extractable PFAS from products. Among products
advertised as water- and/or stain-resistant, detection frequencies
and concentrations of targeted PFAS were similar regardless of green
assurances. This study illustrates many nonessential uses of PFAS
in products used by children and adolescents and suggests that while
water- and stain-resistant assurances can identify products likely
to contain PFAS, current green assurances do not consistently indicate
the absence of PFAS
