- Verbal fluency tasks: effects of age, gender, and educationPublication . Nogueira, Dália; Reis, Elizabeth; Vieira, Ana IsabelObjectives: This study presents data for semantic fluency, phonemic fluency, action fluency, and alternate fluency. The aim is to provide normative data by age, gender, and education for European Portuguese in each fluency category. Methods: Norms for the verbal fluency task were collected from a volunteer population of 444 healthy Portuguese participants. Multiple regression analysis with age, gender, and education as independent variables was performed for the semantic fluency global score, and these variables were considered separately for each phonemic category. Results: Age, education, and gender significantly affected the semantic global score, as well as scores of names, supermarket, kitchen objects, food, and clothes. No gender effect was observed in the categories “p-words,” animals, transports, verbs, and alternating fluency. This last category was only influenced by years of education. Conclusions: Equivalent scores of verbal fluency tasks are useful in clinical practice, allowing the comparison between the normal and the abnormal performance of language disorders.
- Measurement of the photon identification efficiencies with the ATLAS detector using LHC Run-1 dataPublication . ATLAS collaboration (2856 authors); Aguilar-Saavedra, Juan Antonio; Amor Dos Santos, Susana Patricia; Anjos, Nuno; Araque, Juan Pedro; Cantrill, Robert; Carvalho, João; Castro, Nuno Filipe; Conde Muiño, Patricia; Da Cunha Sargedas De Sousa, Mario Jose; Fiolhais, Miguel; Galhardo, Bruno; Gomes, Agostinho; Gonçalo, Ricardo; Jorge, Pedro; Lopes, Lourenco; Machado Miguens, Joana; Maio, Amélia; Maneira, José; Oleiro Seabra, Luis Filipe; Onofre, António; Palma, Alberto; Pedro, Rute; Santos, Helena; Saraiva, João; Silva, José; Tavares Delgado, Ademar; Veloso, Filipe; Wolters, HelmutThe algorithms used by the ATLAS Collaboration to reconstruct and identify prompt photons are described. Measurements of the photon identification efficiencies are reported, using 4.9 fb$^{-1}$ of pp collision data collected at the LHC at $\sqrt{s} = 7$ $\text {TeV}$ and 20.3 fb$^{-1}$ at $\sqrt{s} = 8$ $\text {TeV}$ . The efficiencies are measured separately for converted and unconverted photons, in four different pseudorapidity regions, for transverse momenta between 10 $\text {GeV}$ and 1.5 $\text {TeV}$ . The results from the combination of three data-driven techniques are compared to the predictions from a simulation of the detector response, after correcting the electromagnetic shower momenta in the simulation for the average differences observed with respect to data. Data-to-simulation efficiency ratios used as correction factors in physics measurements are determined to account for the small residual efficiency differences. These factors are measured with uncertainties between 0.5% and 10% in 7 $\text {TeV}$ data and between 0.5% and 5.6% in 8 $\text {TeV}$ data, depending on the photon transverse momentum and pseudorapidity.
