Letter‐case information and the identification of brand names

A central tenet of most current models of visual‐word recognition is that lexical units are activated on the basis of case‐invariant abstract letter representations. Here, we examined this assumption by using a unique type of words: brand names. The rationale of the experiments is that brand names are archetypically printed either in lowercase (e.g., adidas ) or uppercase (e.g., IKEA ). This allows us to present the brand names in their standard or non‐standard case configuration (e.g., adidas , IKEA vs. ADIDAS , ikea , respectively). We conducted two experiments with a brand‐decision task (‘is it a brand name?’): a single‐presentation experiment and a masked priming experiment. Results in the single‐presentation experiment revealed faster identification times of brand names in their standard case configuration than in their non‐standard case configuration (i.e., adidas faster than ADIDAS ; IKEA faster than ikea ). In the masked priming experiment, we found faster identification times of brand names when they were preceded by an identity prime that matched its standard case configuration than when it did not (i.e., faster response times to adidas ‐adidas than to ADIDAS ‐adidas ). Taken together, the present findings strongly suggest that letter‐case information forms part of a brand name's graphemic information, thus posing some limits to current models of visual‐word recognition.     

On the nature of consonant/vowel differences in letter position coding: Evidence from developing and adult readers

In skilled adult readers, transposed‐letter effects (jugde ‐JUDGE ) are greater for consonant than for vowel transpositions. These differences are often attributed to phonological rather than orthographic processing. To examine this issue, we employed a scenario in which phonological involvement varies as a function of reading experience: A masked priming lexical decision task with 50‐ms primes in adult and developing readers. Indeed, masked phonological priming at this prime duration has been consistently reported in adults, but not in developing readers (Davis, Castles, & Iakovidis, 1998). Thus, if consonant/vowel asymmetries in letter position coding with adults are due to phonological influences, transposed‐letter priming should occur for both consonant and vowel transpositions in developing readers. Results with adults (Experiment 1) replicated the usual consonant/vowel asymmetry in transposed‐letter priming. In contrast, no signs of an asymmetry were found with developing readers (Experiments 2–3). However, Experiments 1–3 did not directly test the existence of phonological involvement. To study this question, Experiment 4 manipulated the phonological prime‐target relationship in developing readers. As expected, we found no signs of masked phonological priming. Thus, the present data favour an interpretation of the consonant/vowel dissociation in letter position coding as due to phonological rather than orthographic processing.     

Moral priorities under risk

Many moral theories are committed to the idea that some kinds of moral considerations should be respected, whatever the cost to ‘lesser’ types of considerations. A person’s life, for instance, should not be sacrificed for the trivial pleasures of others, no matter how many would benefit. However, according to the decision-theoretic critique of lexical priority theories, accepting lexical priorities inevitably leads us to make unacceptable decisions in risky situations. It seems that to operate in a risky world, we must reject lexical priorities altogether. This paper argues that lexical priority theories can, in fact, offer satisfactory guidance in risky situations. It does so by equipping lexical priority theories with overlooked resources from decision theory.     

Vécu des situations à risque d’erreur en réanimation : une étude qualitative auprès des médecins et infirmiers

Intensive care units are considered as services with a high risk of error. More and more studies have measured the incidence and impact of errors in intensive care units, but few of them are centered on the impact of the risk of error for professionals. This study focuses on the perception of the risk of error, how it is experienced, and the way in which professionals cope with it. Forty professionals (20 physicians, 20 nurses) participated in clinical interviews. We transcribed recordings and analysed the data using a phenomenological approach. The risk of error is omnipresent in intensive care units. For nurses with less than one years experience, the risk of error is associated with important manifestations of anxiety. On the contrary, for doctors and nurses who have worked for more than one year in ICU, their experience and the relationship of cooperation built with colleagues gives them a feeling of control over risky situations. Our results show that it is important to take into account the risk of error in order to better target the support and training for the ICU professionals.

The Great Mother and the Terrible Mother: mimesis,alterity and attachment in adolescence

This paper discusses attachment, the longing for familiarity and sameness (mimesis), the search for difference and separateness (alterity) and the problem with the Other¹ seen through the lens ofthe individuation process in adolescence. These are explored with reference to relational aspects and Levinas and Girard's divergent views of the Other. The relational space, which in Phillip Bromberg's (2003) words is ‘uniquely relational, but still uniquely individual’ and in which analyst and patient ‘stand together in the space between realities’, might under exceptional circumstances be transformed into ‘a twilight space where the impossible becomes possible’ (p. 573). I will sketch a developmental trajectory starting from primitive states, in which the presence of the Other,as a separate entity cannot be tolerated and where the patient strives for total mimesis. Should the analyst prematurely shatter this illusion, she becomes an alien ‘Other’; a wolf in sheep's clothing. I trace the current psychoanalytic paradigm shift to an emphasis on the co‐creation of meaning in the interpersonal space and explore what alterity consists of and how much of the other's unknowability can be tolerated and respected without a translation into one's own idiom. The clinical vignettes illustrate aspects of therapy which normally lie outside the analytical remit and are culled from an inpatient setting and private practice.     

The segment as the minimal planning unit in speech production: Evidence based on absolute response latencies

A minimal amount of information about a word must be phonologically and phonetically encoded before a person can begin to utter that word. Most researchers assume that the minimum is the complete word or possibly the initial syllable. However, there is some evidence that the initial segment is sufficient based on longer durations when the initial segment is primed. In two experiments in which the initial segment of a monosyllabic word is primed or not primed, we present additional evidence based on very short absolute response times determined on the basis of acoustic and articulatory onset relative to presentation of the complete target. We argue that the previous failures to find very short absolute response times when the initial segment is primed are due in part to the exclusive use of acoustic onset as a measure of response latency, the exclusion of responses with very short acoustic latencies, the manner of articulation of the initial segment (i.e., plosive vs. nonplosive), and individual differences. Theoretical implications of the segment as the minimal planning unit are considered.
