In the setting of a maternal GBS-screening program and successful implementation of the strategy, efforts to improve screening for GBS status remain important. Critical factors that influence the accuracy of detecting GBS maternal colonization are the choice of culture media, the body sites sampled, and the timing of sampling. The evolution of the different culture options to improve the GBS-screening strategy will be reviewed. Despite efforts related to sampling and culture procedures, false-negative GBS-screening contributing to continuing EOGBS cases and false-positive screening leading to unecessary IAP, occur. As GBS carriage is highly variable, the predictive values of GBS antenatal cultures are not always good predictors of the maternal GBS status at presentation for delivery. Rapid non-cultural GBS screening methods have been developed: antigenic tests are not sensitive enough to replace antenatal screening cultures but available real-time PCR have faired better in the detection of GBS. Real-time PCR tests could improve effectiveness of the screening-based strategy and lead to a further reduction of the incidence of EOGBS disease. However questions of costs and logistics remain unanswered. Either for therapy or for intrapartum chemoprophylaxis, penicillin G for its bactericidal activity and narrow spectrum, remains the agent of choice. But in the true penicillin allergic patients, clindamycin or erythromycin have been recommended as alternative drugs. However, probably as a consequence of the important use of macrolides, related drug resistance among streptococcal isolates is currently recognized in many countries. Epidemiology of resistance to antimicrobial agents will be presented. [less ▲]

The use of new technologies and the merging of our libraries have led us to think about marketing our library services. At the same time, Belgian universities in the French Community decided to conduct the LibQual+ survey. We participated in the working group responsible for data analysis of this survey regarding our institution. This gave us an initial assessment of the level of user satisfaction in our library, pointing to general library strengths and weaknesses and highlighting several questions to be investigated further. We searched for alternative evaluation methods that could help us to validate the LibQual+ conclusions and to explore further certain issues regarding different library user groups (students / researchers / clinicians / academic professors). Methodologies for conducting focus groups, semi-structured interviews and participant observations are largely described in the literature. We propose to test and compare these methodologies in order to discover which method is the most appropriate for each type of user and how far these approaches may be complementary. We also want to verify whether these investigation strategies will lead to reproducible conclusions able to support strategic planning for the library. Lastly, we need to decide whether these methods could also be used to measure the impact of future marketing activities. It may be useful to share our working procedures, conclusions and experiences with colleagues involved in similar marketing challenge. [less ▲]

Additive technologies offer the possibilities to build complex geometries with integrated functionalities, specific to target application. 3D-printing of metallic powder is an additive technology proceeding in 2 steps: a green part is first built layer by layer by printing a liquid binder on the powder bed, and then green part is debinded and sintered. As sintering occurs separately of shaping process, 3D-printing is one of the only additive techniques able to produce porous parts, as filters or other fluid permeable components. Different porous characteristics can be obtained by playing on process parameters. [less ▲]

Governments and public authorities are increasingly relying on Public-Private Partnerships for the provision of public goods and services. It is often argued that the use of a public private partnership can relieve the government from a strained budget constraint and, in this paper, we analyze the choice of a contractual solution for designing, constructing and managing a project, with observable externalities, by a budget-constrained government. We show that the quality of the project and the designed contractor are affected by the extent of the budget constraint and we show that the use of a PPP may partially overcome the resulting inefficiencies.

Towards the end of the 20th century, as the propagation of new discourses of ethnic success generated new versions of the American Dream, “America” came to signify not only immigrant mobility and whiteness, but also multiculturalism. As Inderpal Grewal argues in Transnational America, this paradox of sorts was only made possible through a slippage in the meaning of “white,” within which whiteness still connoted Anglo-America, yet extended its meaning to include a more heterogeneous group that passed as white through the endorsement of culturally-specific consumerist practices and middle-class norms of behaviour. Posing as multicultural yet covertly fastening whiteness to an ideal Americanness, these so-called “new” versions of the American Dream elevated the Asian American community to “model minority” status, thus contributing to rationalize away the lure that a “relative whiteness” could somehow be acquired by non-white minority groups. Drawing on whiteness studies and psychoanalytical theory, my paper will explore representations of interracial relationships as a means to claim and/or contest the ideal of whiteness in Mohsin Hamid’s The Reluctant Fundamentalist. In Hamid’s novel, the 9/11 attacks trigger a crisis in self-identification for model-minority protagonist Changez, which proves illuminating in terms of the invisible racial subjugation exerted so far onto him by Jim, Changez’s passport into the corporate world, and by Erica, his (white) lifeline to exclusive Manhattan. My paper will focus on the ways in which Hamid uses the post 9/11 context to reveal the racial melancholia surreptitiously informing today’s “new” versions of the American Dream, which is apparent in Changez’s and Erica’s relationship as well as in their parallel impossible mourning of the broken mirror of “white” Am/Erica. Emphasizing the extent to which whiteness and racial melancholia permeate the discourse of assimilation, Hamid’s book rewrites the “new” American Dream as a “fantasy built on absences” (Anne Anlin Cheng).

Les caractéristiques du langage adressé à l’enfant ont un impact important sur l’acquisition langagière, tant chez les enfants présentant un développement normal du langage que pour ceux qui ont des troubles langagiers. Mais, pour ces derniers, le bénéfice lié à un input optimal est plus important que chez les enfants sans trouble (Snow, 1994). Malheureusement, en raison même du retard de développement du langage, l’ajustement du langage de l’adulte à l’enfant est rendu plus difficile (D’Ordorico & Jacob, 2006). On se trouve dans une spirale négative : les enfants fragiles au niveau langagier dépendent plus que leurs pairs de la qualité de l’input qui leur est proposé et, à cause de leurs difficultés langagières, ils suscitent des interactions moins riches et moins à même de les soutenir dans leur développement langagier ultérieur. Face à ce constat, des programmes d’intervention ont été mis en place (Girolametto, Weitzman, & Greenberg, 2004). Dans ce travail, nous présenterons les résultats obtenus suite à une session de guidance parentale organisée avec les parents de 4 enfants d’environ 4 ans présentant un retard de développement de langage. L’objectif de cette formation est d’aider les parents à tenir un rôle d’acteur principal dans le développement langagier de leur enfant, en lui donnant des occasions de communiquer, en suivant ses intérêts, en le plaçant dans des routines prévisibles et familières, et en lui fournissant un langage plus adapté à ses difficultés. Dans un premier temps, chaque enfant a été filmé en interaction avec ses parents afin de disposer de mesures pré-thérapeutiques concernant le niveau langagier et communicatif de l’enfant et les stratégies d’interaction parentales. Ensuite, deux orthophonistes ont travaillé avec le groupe de parents afin de les familiariser aux stratégies utilisées dans les programmes d’intervention parentale. Ces stratégies sont les suivantes (Girolametto, 2004) : 1) les stratégies centrées sur l’enfant (par exemple, se mettre au niveau de l’enfant, attendre que l’enfant initie l'interaction) ; 2) les stratégies de promotion de l’interaction (par exemple, encourager l’enfant à prendre leur tour dans une interaction, à poser des questions) ; 3) les stratégies de modelage du langage (par exemple, l’expansion, la reformulation, etc). Enfin, deux séances de post-thérapie ont été réalisées, la première directement après la session de formation, la seconde 6 mois plus tard. Chaque film a été transcrit et analysé. Les résultats, qui seront présentés et discutés, ont des implications importantes en termes de prise en charge précoce des enfants présentant des troubles de développement langagier. [less ▲]

Pharyngo Laryngeal Reflux (PLR) influences the voice quality : hoarseness, vocal fatigue and hypertonia (Shaw et al, Hopkins et al). Our goal is to measure the influence of the PLR on the voice of 96 subjects by using the Belafsky’s reflux symptom index (RSI) and reflux finding score (RFS). 46 dysphonic patients (26M/24F) constitute the experimental group (EG) and 50 subjects (13 M/33F) without vocal or gastric complaint the control group (CG). All are evaluated by subjective measures (RSI), D-type scale (DS-16, Denollet et al) and objective measures (Video Laryngo Stroboscopy, RFS). The EG shows a RSI score significantly higher on test than on the retest (p=0.002). The specificity of the RSI calculated on the CG amounts to 98 % (chi ²: p < 0,05, Cramer: 0,678). The EG scores are significantly higher than those of the CG (p=0,000) although the CG obtains scores significantly higher as for the eating risk habits (p=0,001). In the EG, we note a correlation between the coffee consumption, the item 9 (pyrosis) (rho: 0,32; p < 0,05 ) and the global RSI score (rho: 0,35; p < 0,05). In the CG, alcohol consumption influences significantly the item 9 (rho: 0,47). The correlations between RSI and RFS are not significant (p < 0.05). The ENT evaluation is severe and probably influences the result. We observe no influence of the gender and of the D-type scale on the RSI scores (p <0.05). The RSI scale is an interesting tool for the detection of RPL. [less ▲]

Computation of lactation yields from test-day data has lost much of its importance for genetic evaluations as the use of test-day models is currently quite widespread. In the other hand its interest for intra-farm management is increasing as a base for advanced management tools. The first and principal aim of this study was to develop a method which takes into account advantages and disadvantages of existing methods, and to test its potential to provide useful management tools to dairy farmers. A test-day model with modifications to able daily run and management tools was developed. Because of its similarities with best prediction, the method developed here was called modified best prediction. The second objective was to compare the accuracy of this new method with best prediction and test interval methods. Modified best prediction showed good results for predicting daily yields and was slightly better than best prediction for lactation yields prediction. Management tools obtained with modified best prediction are explained. [less ▲]

The question of lowering the voting age to 16 has long been debated in university circles. In the last Austrian elections, young people aged 16 and older were invited to vote, even if young people themselves are divided over this issue, even hostile to the idea. Nevertheless, isn’t such a question, which is rarely discussed by the larger public and touches on several dimensions of a person’s life, an ideal topic for a debate, where the confrontation of ideas may change opinions and reveal – or even modify – young people’s global attitudes towards political interest and participation? A non-random sample of nearly two hundred 16- to 22-year-old youth in French-speaking Belgium was selected to discuss the possibility of lowering the voting age to 16, as well as political interest and political participation, during one day with four experts. The same questionnaire was filled in in the beginning and at the end of the day. These first results are presented here. They show little evolution during the discussion, in a sample already largely against the idea of lowering the voting age. However, these are the consequences for political socialisation we would like to discuss with this research project based on political reasoning. [less ▲]

We present a seismic analysis of the pulsating hot B subdwarf KPD 1943+4058 (KIC 005807616) on the basis of the long-period, gravity-mode pulsations recently uncovered by Kepler. This is the first time that g-mode seismology can be exploited quantitatively for stars on the extreme horizontal branch, all previous successful seismic analyses having been confined so far to short-period, p-mode pulsators. We demonstrate that current models of hot B subdwarfs can explain quite well the observed g-mode periods, while being consistent with independent constraints provided by spectroscopy. We identify the 18 pulsations retained in our analysis as low-degree (l = 1 and 2), intermediate-order (k = −9 through −58) g-modes. The periods (frequencies) are recovered, on the average, at the 0.22% level, which is comparable to the best results obtained for p-mode pulsators. We infer the following structural and core parameters for KPD 1943+4058 : Teff = 28,050 ± 470 K, log g = 5.520 ± 0.029, M∗ = 0.4964 ± 0.0013 M⊙, log (Menv/M∗) = −2.552 ± 0.070, log (1−Mcore/M∗) = −0.366 ± 0.010, and Xcore(C+O) = 0.2612 ± 0.0080. We additionally derive the age of the star since the Zero-Age EHB 18.4 ± 1.0 Myr, the radius R = 0.2026 ± 0.0070 R⊙, the luminosity L = 22.92 ± 3.13 L⊙, the absolute magnitude MV = 4.21 ± 0.11, the reddening index E(B − V ) = 0.094 ± 0.017, and the distance d = 1183 ± 93 pc.

Whereas it is obvious that the failure process can vary from one firm to another (Argenti, 1976; D'Aveni, 1989; Laitinen, 1991), to date, few researchers have worked on the detection of several explanatory failure patterns. In addition, none of the reviewed research really focuses on small firms while their failure is important and particular (Haswell and Holmes, 1989). Considering these observations and on the basis of two complementary statistical analyses (Thiétart, 2003), this paper identifies, among a sample of 208 small distressed firms, a taxonomy of five explanatory business failure patterns, i.e. five homogeneous groups of small firms on the basis of the reasons for their failure. These five patterns are the following ones : shocked firms (1), firms serving other interests (2), apathetic firms (3), firms that fail after a punctual managerial error (4) and badly-managed firms (5). The results of this paper are consistent with previous literature but they shed new lights on the understanding of the reasons for small business failure. As the detection of the fundamental explanatory failure factors is the basis of failure prevention (Argenti, 1976), the identification of these patterns is of crucial importance for a better understanding and for a better prevention of this phenomenon.

GPS dual frequency L1/L2 measurements have been used for many years to reconstruct the ionosphere Total Electron Content and to detect small-scale irregular structures in the ionospheric plasma. TEC is usually computed by forming the geometry-free combination of L1/L2 phase measurements. Most of the existing techniques use the geometry-free combination of code measurements to solve the non-integer geometry-free ambiguity. This methodology requires the computation of satellite and receiver hardware biases. In addition, the quality of the ambiguity resolution process strongly depends on code multipath. New signals from Galileo and from modernized GPS offer new opportunities for TEC reconstruction. First attempts to compute TEC using triple frequency measurements from modernized GPS (L1/L2/L5) and from Galileo (E1, E5a, E5b) give very promising results but, at the present time, only a few triple frequency GPS/Galileo receivers are available. The University of Liege has purchased two Septentrio PolaRx3G receivers which allow tracking GPS L1/L5 and Galileo E1/E5a signals. These receivers have been installed at the Geophysical Observatory of Dourbes (50.1°N, 4.6° E) and are continuously tracking all GPS and Galileo satellites in view (including GPS SVN49/PRN01, Giove A and Giove B) since November 2009. The paper analyzes the added value of L1/L5 and E1/E5a geometry free combinations and of the new GPS and Galileo signals for TEC reconstruction. It discusses the influence of multipath and of SVN49/PRN1, Giove A and Giove B hardware biases. [less ▲]

Objective: In the recovery from coma, the acquisition of command following represents an important milestone, indicating emergence from the vegetative state. In some patients, recovery of consciousness may precede motor recovery. Brain-computer interfaces (BCI) might permit these patients to show non-motor dependent signs of awareness and in a next step might enable communication. This study aimed at testing to what extent an EEG-based BCI could help detecting signs of awareness and communication in disorders of consciousness. Methods: We studied 13 patients with a minimally conscious state (MCS, 5 TBI – 8 anoxic, mean time post injury 70±109 months; mean age 42 ± 21) and 16 healthy controls (aged 45±19). Patients were evaluated using the Coma Recovery Scale Revised. 16-Channel EEG was recorded using a g.tec USBAmp amplifier. An auditory P300 four choice speller paradigm based on the BCI2000 system was used. Subjects were asked to answer yes or no to simple questions by paying attention to one out of four auditorily presented stimuli (‘yes’, ‘no’, ‘stop’, ‘go’). A trial constituted of 15 presentations of each sound the order of presentation being randomized. After a training session, patients and healthy subjects were required to answer 10 to 12 questions. A stepwise linear discriminant analysis based on the training session was used to classify the data. Offline, all training and testing trials were pooled and a leave-one-out approach was used to classify the data. Results: Healthy subjects presented a mean correct response rate of 73% online and 93% offline. Three MCS patients had a correct response rate of ≥50% offline (10, 18, 0% online and 50, 53, 57% offline). Two of these three patients did not show any command following at the bedside. The 10 remaining MCS cases showed online and offline correct answers <50% (mean 33±9% online and 25±13% offline). Conclusion: Our auditory P300-based BCI permitted functional interactive communication in 15/16 controls (online) and in all offline. Our data obtained in patients with disorders of consciousness demonstrate the potential clinical usefulness of the technique following coma but also show lower accuracy in patients as compared to healthy volunteers. This might be due to fluctuating attentional levels and exhaustibility in the MCS and to the suboptimal EEG recording quality due to movement, ocular and respiration artifacts in these challenging patients.

This paper presents the adaptation of the LARSP (Language Assessment, Remediation and Screening Procedure) (Crystal et al., 1976) from English into French based on the analysis of a corpus of French speaking children ranging between the ages of 18 months and 5 years. Included is a description of particularities of French morphosyntax and the ensuing adaptations that are reflected on the new French LARSP (F-LARSP) chart. The LARSP is a linguistic profile commonly used by researchers and clinicians to carry out “comprehensive and consistent linguistic analysis” (Ball, 1999); more specifically a detailed analysis of the grammar and morphology of children’s spontaneous language samples. The profile was developed in a manner that allows the user to clearly see the child’s grammatical strengths and weaknesses in relation to their chronological age. This is made possible by the notion that the order in which syntactic structures are acquired is relatively stable, at least until the approximate age of 5. Correlation of a child’s morphosyntactic production to their age provides the therapist with vital information regarding an array of areas including the possible diagnosis of language impairment, remediation planning, and measuring treatment efficacy carried out since the last profiling session. The tool is therefore useful for professionals working with children who are suspected of or who have been diagnosed with having forms of language difficulties such as Specific Language Impairment (SLI) where morphology and syntax are commonly affected. The utility of the LARSP, originally designed for Anglophone use, has led to its adaptation to several other languages. Those which have been published for an international audience include Welsh (1988), Dutch (1987), Irish (1990) and Persian (1998). [less ▲]

The lateral and medial knee contact forces are estimated directly from the knee modeled as a modified revolute joint. As such, this study presents what can be achieved by estimating the knee contact forces from a simplified knee model. [less ▲]

This paper aims to evaluate Senegalese consumers' willingness-to-pay (WTP) for local fresh milk-based products, in opposition to the ones produced with imported powder. Exploiting data from a choice-based-conjoint analysis conducted on 400 households in the region of Dakar, we evaluate the premium that consumers are willing to pay for fresh raw material (rather than powder) in the composition of sour milk. Based on an Ordered Probit Model, the results show evidence for a positive WTP for fresh raw material, which may be seen as a strong indication of preference for local products. This WTP greatly depends on the characteristics of the households. Wealthier households are willing to pay more than the medium households, while big households are ready to pay much less than the base category ones. Obviously, some niche markets exist, that producers may target to sell the local milk-based dairy products. However, more information has to be provided about the composition of dairy products, as consumers are not currently able to distinguish both types of raw material, even if they are willing to pay more for one of them. In spite of some restrictions about the presence of a potential "hypothetical bias" due to the nature of the data, this study gives a first insight of consumers' preferences for local milk-based dairy products.

Milk coagulation has a direct effect on cheese yield. Several factors influence the milk coagulation kinetics. In addition to calcium and milk protein concentrations, titratable acidity influences all the phases of milk coagulation. The objective of this research was to study the feasibility of prediction of titratable acidity directly in bovine milk using mid-infrared spectrometry. In order to maximize the variability in the measurements of titratable acidity, milk samples were collected on basis of several criteria (e.g. breeds). The titratable acidity was recorded as Dornic degree. All samples were also analyzed by MIR spectrometry. Using partial least squares regressions and first derivative pretreatment of spectral data, a calibration equation was built to predict the Dornic degree in cow milk. First results were promising and showed the potentiality to this calibration. The calibration and cross-validation coefficients of determination were 92.25 and 89.88 %, respectively. Moreover, the ratio of standard error of prediction to standard deviation was 3.13 and permits us to consider the calibration equation as usable in most application such as scientific researches and the screening of the Walloon dairy herd particularly in order to improve the milk coagulation properties.

A complete ichthyosaur rostrum with 124 associated teeth was recently discovered in Laux-Montaux locality, department of Drôme, southeastern France. The associated belemnites and ammonites indicate a late Valanginian age (Neocomites peregrinus Zone, Olcostephanus nicklesi Subzone) for this fossil, which consequently represents the first diagnostic ichthyosaur ever reported from Valanginian strata. Despite its incompleteness, this specimen is perfectly consistent with Aegirosaurus leptospondylus WAGNER 1853 and is therefore referred to this rare taxon. This specimen thus greatly increases the temporal and geographic biozones of this taxon, which was previously restricted to the Tithonian (Upper Jurassic) lithographic limestones of Bavaria (southern Germany). Moreover, it indicates that Late Jurassic ichthyosaurs actually crossed the Jurassic-Cretaceous boundary with a much lighter diversity drop than previously supposed. Finally, tooth morphology and wear pattern suggest that Aegirosaurus belonged to the “Pierce II/ Generalist” feeding guild sensu Massare (1987; 1997), which was hitherto not represented in post-Liassic ichthyosaurs.

The use of acoustic diffusers to reduce noise in urban areas has been recently numerically investigated [Acta Acustica united with Acustica, Vol. 95 (2009), p. 653–668]. It was shown that a significant noise reduction can be observed by considering diffusers on the building façades. In the present study, an experimental investigation is proposed to validate last results. Measurements are carried out using a 1:10 urban street scale model, with and without acoustics diffusers, in order to evaluate the “real” effect of such devices, for several configurations. Results, in terms of sound attenuation and reverberation, show that a positive effect can be observed, provided that diffusers are well designed for the reduction of road traffic noise. [less ▲]

My intention is to put the problem of objectivity under examination from a very specific viewpoint, namely by focusing on the theory of judgement, which has been defended in the so-called South-Western School of neo-Kantianism. As one knows, the main representatives of this School are Wilhelm Windelband, Heinrich Rickert, Emil Lask and Bruno Bauch. Those authors are known, first and foremost, for having supported the view that valuation and assumption of values play a basic role in almost all the domains of our life, including our scientific life. This view forms the basis of their theory of knowledge or epistemology, which is prior to any methodological distinction between natural and cultural sciences (so it would be misleading to say that they confine that view to their foundation of cultural sciences and humanities). What, then, does such an ‘axiological’ theory of knowledge exactly mean? What does it imply for the construction of a theory of objectivity? And how is it related to Kant’s foundational program?

The purpose of this study was to evaluate how stimulus meaning and subject’s expertise differentially influence visual memory and visual search. In order to answer this question, 20 novices and 20 experts (art historians) performed both long term visual memory (LTVM) and visual search tasks with abstract and non-abstract stimuli (paintings). In the LTVM task, subjects were presented 100 abstract and 100 non-abstract paintings and after each stimuli set presentation, they performed a 3-forced-choice recognition test. In the visual search task, subjects had to find targets as quickly as possible in abstract or non-abstract paintings. Our data showed experts performed better than novices in LTVM task for both abstract and non-abstract stimuli, whereas novices and experts had a similar performance in the visual search task. This result suggests expertise and thus previous knowledge about the stimulus increase memory performance but not visual search performance. Concerning the type of stimulus, performance in LTVM with non-abstract paintings was better than with abstract paintings while the contrary was observed in the visual search task. Stimulus meaning is thus a significant factor for visual memory (as also shown by Chatterjee et al., JOV, 2008) but not for visual search. In conclusion, our findings suggest stimulus meaning and subject’s expertise influence VLTM but not visual search. These results confirm that VLTM is rather conceptual and influenced by top-down processes (like meaning and expertise) while visual search is rather perceptive and influenced by bottom-up processes (as suggested by Konkle, JEP, in press).

Prerequisites for the implementation of a new heroin-assisted centre Background: TADAM, a randomised controlled trial of heroin-assisted treatment, will begin in Liège, Belgium, in 2010. Heroin-assisted treatment of treatment resistant heroin addicts has been successfully tested in six countries: Switzerland, The Netherlands, Spain, Germany, Canada and United-Kingdom. Each country used a randomised controlled trial to assess this new treatment. It has now a strong evidence-based foundation. However in the peer-reviewed articles, there is little information on the concrete conditions to fulfil before implementing this treatment. With the experience of the other countries and ours, we have listed those conditions. Methodology: We collected information concerning the randomised controlled trial. This included articles published in international peer-review journals, reports, visits to heroin-assisted treatment centres and information given by researchers who participated in those experiments. We will illustrate our presentation with the example of Liège. Results: Before all, a political agreement at the national level is mandatory. It is never guaranteed even if it was already given in the past. Methadone treatments must be available and the collaboration with the addiction network will be an advantage for the project. There must be a sufficiently high number of heroin addicted in the concerned area and they must be correctly informed about the heroin-assisted treatment. But even if it is the case, the inclusion of the foreseen number of patients can be more difficult than expected because it is problematic to assess the exact number of patients fulfilling the inclusion criteria and because not all the eligible participants will accept to enter this treatment. Conclusion: For reasons other than medical or scientific ones, implementing a new heroin-assisted centre is still a challenge. [less ▲]

Several studies showed that it is more difficult to retrieve semantic information from recognized voices than from recognized faces. However, earlier studies that investigated the recall of biographical information following person recognition used stimuli that were pre-experimentally familiar to the participants, such as famous people’s voices and faces. The present study was designed in order to allow a stricter control of frequency exposure with both types of stimuli (voices and faces). In the present study, subjects had to associate lexical (i.e., name) and semantic information (i.e., occupation) with faces or voices. When asked later to recall semantic information being cued by the person’s names, participants provided significantly more occupations for the targets that had been previously associated with faces than with voices. These results and their implications for current Interactive Activation and Competition person recognition models are discussed. Finally, the potential role of the relative distinctiveness of voices and faces is also considered. [less ▲]
