Le comportement de « prise de parole » (voice) : validation de la version française de la mesure de Maynes et Podsakoff

Voice is an essential behaviour that can inhibit or generate processes of innovation and organisational change. To date, few measurement scales adapted to the French context and allowing to analyse this behaviour exists. This article proposes to translate the 4’factors Voice scale from Maynes and Podsakoff (2014). The translation of this scale was tested by 4 studies on different samples of 1275 French workers from various organisational backgrounds. The first studies test the reliability, internal consistency, divergent and convergent validity of the scale. Then, a gender invariance analysis tests the metric properties of the scale. The results obtained present acceptable psychometric qualities that validate the French version.     

The interaction of meaning and sound in spoken word recognition

Models of spoken word recognition vary in the ways in which they capture the relationship between speech input and meaning. Modular accounts prohibit a word’s meaning from affecting the computation of its form-based representation, whereas interactive models allow activation at the semantic level to affect phonological processing. We tested these competing hypotheses by manipulating word familiarity and imageability, using lexical decision and repetition tasks. Responses to high-imageability words were significantly faster than those to low-imageability words. Repetition latencies were also analyzed as a function of cohort variables, revealing a significant imageability effect only for words that were members of large cohorts, suggesting that when the mapping from phonology to semantics is difficult, semantic information can help the discrimination process. Thus, these data support interactive models of spoken word recognition.     

The effect of arbitration program characteristics on applicants' intentions toward potential employers

The authors examined intentions toward prospective employers with different alternative dispute resolution (ADR) policies and no ADR policy. In Study 1, students (N = 124) were randomly assigned to 1 of 4 conditions in which 2 variables, arbitration policy presence or absence and firm desirability, were manipulated. The presence of a voluntary, nonbinding arbitration policy had no impact on intentions and did not interact with firm desirability. In Study 2, students (N = 273) were randomly assigned to 1 of 8 conditions (mandatory vs. voluntary arbitration, binding vs. nonbinding arbitration, and highly desirable vs. less desirable employer). Both mandatory and binding arbitration policies were related to less favorable intentions toward firms. Predictions regarding the interaction of ADR policy and firm desirability were partially supported. Some support was found for the interaction between ADR policy and ethnicity.     

Public trust and confidence in legal authorities: What do majority and minority group members want from the law and legal institutions?*

Discussions of public trust and confidence in the police and the courts often assume that the key to public feelings is the public's evaluation of the outcomes that the public receives from these legal authorities. In the case of the courts, discontent is often assumed to be linked to issues of cost and delay-instrumental concerns about the outcomes delivered to the public by the courts. In the case of the police, the inability to effectively control crime is frequently seen as driving public evaluations. This article presents an alternative procedural justice based model that links public trust and confidence to views about the manner in which legal authorities treat the public. Drawing upon psychological research about public evaluations of institutions and authorities it is argued that the key issue that shapes public views is a process based evaluation of the fairness of the procedures that the police and courts use to exercise their authority. Analyses from several studies exploring the basis of public views support this procedural justice based model of public evaluation. In addition, the results provide suggestions about the elements of procedures that are central to public judgments about their fairness.     

How not to be seen: the contribution of similarity and selective ignoring to sustained inattentional blindness

When people attend to objects or events in a visual display, they often fail to notice an additional, unexpected, but fully visible object or event in the same display. This phenomenon is now known as inattentional blindness . We present a new approach to the study of sustained inattentional blindness for dynamic events in order to explore the roles of similarity, distinctiveness, and attentional set in the detection of unexpected objects. In Experiment 1, we found that the similarity of an unexpected object to other objects in the display influences attentional capture: The more similar an unexpected object is to the attended items, and the greater its difference from the ignored items, the more likely it is that people will notice it. Experiment 2 explored whether this effect of similarity is driven by selective ignoring of irrelevant items or by selective focusing on attended items. The results of Experiment 3 suggest that the distinctiveness of the unexpected object alone cannot entirely account for the similarity effects found in the first two experiments; when attending to black items or white items in a dynamic display, nearly 30% of observers failed to notice a bright red cross move across the display, even though it had a unique color, luminance, shape, and motion trajectory and was visible for 5 s. Together, the results suggest that inattentional blindness for ongoing dynamic events depends both on the similarity of the unexpected object to the other objects in the display and on the observer's attentional set.

Wearable activity schedules to promote independence in young children

Activity schedules consist of a series of visual discriminative stimuli, arranged in booklets or binders, which function as prompts for appropriate behavior. Although activity schedules are useful, their typical presentation in binders can be cumbersome and stigmatizing, placing additional barriers for independence and inclusion. The purpose of the present studies was to evaluate the usefulness of a wearable activity schedule and determine whether prompts provided by it would be sufficient to support completion of a complex chain of behaviors by young children. In Experiment 1, the Octopus watch® provided prompts to children of typical development to complete a morning routine independently. In Experiment 2, the usefulness of the watch was evaluated in children with autism spectrum disorder engaged in play activities in a clinical setting. In both experiments, children reliably displayed a greater proportion of independent engagement in target behaviors when prompts were delivered by the watch compared to control conditions.     

Varying acoustic-phonemic ambiguity reveals that talker normalization is obligatory in speech processing

The nondeterministic relationship between speech acoustics and abstract phonemic representations imposes a challenge for listeners to maintain perceptual constancy despite the highly variable acoustic realization of speech. Talker normalization facilitates speech processing by reducing the degrees of freedom for mapping between encountered speech and phonemic representations. While this process has been proposed to facilitate the perception of ambiguous speech sounds, it is currently unknown whether talker normalization is affected by the degree of potential ambiguity in acoustic-phonemic mapping. We explored the effects of talker normalization on speech processing in a series of speeded classification paradigms, parametrically manipulating the potential for inconsistent acoustic-phonemic relationships across talkers for both consonants and vowels. Listeners identified words with varying potential acoustic-phonemic ambiguity across talkers (e.g., beet/boat vs. boot/boat) spoken by single or mixed talkers. Auditory categorization of words was always slower when listening to mixed talkers compared to a single talker, even when there was no potential acoustic ambiguity between target sounds. Moreover, the processing cost imposed by mixed talkers was greatest when words had the most potential acoustic-phonemic overlap across talkers. Models of acoustic dissimilarity between target speech sounds did not account for the pattern of results. These results suggest (a) that talker normalization incurs the greatest processing cost when disambiguating highly confusable sounds and (b) that talker normalization appears to be an obligatory component of speech perception, taking place even when the acoustic-phonemic relationships across sounds are unambiguous.
