The execution of a task necessitates the use of a specific response modality. We examined the role of different response modalities by using a task-switching paradigm. In Experiment 1, subjects switched between two numerical judgments, whereas response modality (vocal vs. manual vs. foot responses) was manipulated between groups. We found judgment-shift costs in each group, that is irrespective...

It is well-known that the Interparticle interactions between adsorbates and surface of an adsorbent can affect the surface morphology. One of the consequences of this issue is that the resonant frequency of a nanoscale resonator can be changed due to adsorption. In this study we have chosen a cantilever-based nanoscale mass-sensor with a single nanoparticle at its tip. Using the classical...

PURPOSE/OBJECTIVES To explore the response shift phenomenon in pediatric patients with cancer and to determine its effects on ratings of health-related quality of life (HRQOL). DESIGN Retrospective pre- and post-test design. SETTING Pediatric oncology department in the northern part of the Netherlands. SAMPLE 37 children newly diagnosed with cancer and 80 parents. METHODS The then-test ...

Behavioral and electrophysiological evidences have shown that locus ceruleus (LC) is involved in different tasks including modulation of sensory processing and shift of attention. In the present study, single unit responses of barrel cortical cells was recorded following controlled mechanical displacement of the principal and peripheral vibrissae in adult rats (100 trials of 200 µm deflection f...

Background & Aims of the Study: To prevent lots of work-related accidents in different industries and workplaces, managers should consider macro-factors such as safety culture and its elements like safety climate as the main subject to reflect attitude toward safety . This study aimed at finding the best work shift group in an Iranian process industry by safety attitude/climate...

Objective(s): In the present study, the effect of tissue incubation with propranolol on functional antagonism of Zataria multiflora Boiss (Z. multiflora) at muscarinic receptors of tracheal smooth muscle was examined.  Materials and Methods: The effects of three concentrations of aqueous-ethanolic extract, 10 nM atropine, and saline on muscarinic receptors were tested on incubated tracheal smoo...
