Parsing complex acoustic scenes involves an intricate interplay between bottom-up, stimulus-driven salient elements in the scene with top-down, goal-directed, mechanisms that shift our attention to particular parts of the scene. Here, we present a framework for exploring the interaction between these two processes in a simulated cocktail party setting. The model shows improved digit recognition in a multi-talker environment with a goal of tracking the source uttering the highest value. This work highlights the relevance of both data-driven and goal-driven processes in tackling real multi-talker, multisource sound analysis.
We describe a rare occurrence of pericentric inversion in homologues of chromosome 9 observed in a 2-mo-old female baby with eye and brain abnormalities. Her clinical and neuroradiological features are similar to the signs of Walker-Warburg syndrome. We found the same inversion in heterozygous condition in all metaphases of both parents, who are related, and in two grandparents and their mother. The cytogenetic abnormality alone does not explain the phenotype in this patient, but it warrants further linkage studies with emphasis on the pericentric region of chromosome 9 in patients with Walker-Warburg syndrome phenotype. This family case is unique and raises suspicions about whether the pericentric region of chromosome 9 has any connection with the phenotype of Walker-Warker syndrome.

Participants were 235 undergraduate students. Results of confirmatory factor analysis demonstrated that the seventeen items loaded on five factors ( reactive/generative, differentiation, organization, communication and search) and the fivedimensional model was well fit (x²= 267.62, df= 159, RMSEA= .076, CFI= .94, IFI= .94, SRMR= .069). Internal consistency reliability coefficients were .75 for search subscale, .87 for differentiation subscale, .86 for organization subscale, .88 for reactive/generative subscale, .83 for communication subscale, .94 for overall scale. The corrected item-total correlations ranged from .52 to .77. These results demonstrate that this scale is a valid and reliable instrument.
