When Is Believing “Seeing”? Hostile Attribution Bias as a Function of Self‐Reported Aggression1

Repeated exposure to adverse advents (e.g., risky driving) was thought to increase expectations for the recurrence of the event. Community‐based drivers (130 men, 133 women) were given scenarios depicting everyday road events that could be construed as benign, ambiguous, or malign by the degree of perceived provocation. Differences between levels of gender, ethnicity, age, aggressiveness, and provocation were measured by attributions of intent, hostility, and anger. Results showed that, overall, drivers accurately perceived provocation conditions. Hostile attributional biases were not evident among the sample as a whole, but were dependent on level of aggressiveness and provocation. Analysis of self‐reported driving behavior showed that young, aggressive majority group drivers who experience greater aggression on the road also were more likely to take more risks while driving. Controlling for miles driven, gender differences were not found.     

Lesions of the dorsal subiculum and the dorsal hippocampus impaired pattern separation in a task using distinct and overlapping visual stimuli

The contribution of the dorsal subiculum (DS) and of the dorsal hippocampus (DH) to memory for distinct and overlapping visual stimuli was examined. Rats with selective lesions of the DS or the DH were compared to sham-operated rats on a delayed matching-to-place task guided by distal visual cues in a modified radial-arm maze. Overlapping distal visual cues could be perceived from three arm entrances (adjacent arms) and a unique set of distal cues were more likely to be seen from the other two arm entrances (distinct arms). Rats with DS lesions were impaired on trials with baited adjacent arms, but not on trials with baited distinct arms. Rats with DH lesions were impaired on both types of trials. These results suggest that the DS and the DH are necessary for pattern separation and that they may have different contributions to memory.     

Un pas supplémentaire vers l’autonomie de la réparation du défaut d’information médicale !

Question of the nature of the liability and damage repairable in case of failure in the delivery of health information since 2010 is in the heart of debates. Progressively, there is an autonomy movement of the disclosure and together with a detachment of prejudice to the notion of loss of chance. This information is particularly expected when the practitioner uses a product outside of the authorization for placing on the market.     

Health Care Ethics Consultation: 'Training in Virtue'

In philosophy, intelligence is less important than character, or so Wittgenstein once argued. In this paper, in a similar vein, I suggest that in health care ethics consultation character is of preeminent importance. I suggest that the activity of ethics consultation can be understood as "training in virtue," and what distinguishes the good health care ethics consultant from his/her average colleague are differences in traits of character. The underlying assumption is that one's use of knowledge and abilities are ultimately a function of who one is and how one perceives and confronts situations of moral uncertainty and conflict. In discussing the original case presented by Mark Bliton, I focus on the virtues of wisdom, justice, courage, compassion and humility.     

Selective adaptation of English consonants using real speech

Most English consonant-vowel (CV) syllables have other CV syllables embedded within them. For example, splicing sufficient energy from the onset of [k^ha] yields [p^ha], splicing into [ma] or [va] yields [ba], and splicing into [?a] yields [da]. We spliced successively longer segments from naturally spoken CV syllables to produce sequences of CV syllables which varied in discrete acoustic steps from [k^ha] to [p^ha], from [?a] to [da], from [ma] to [ba], from [fa] to [ba], and from [va] to [ba]. Random presentation of syllables in each series resulted in identification functions with typically sharp phoneme boundaries. For example, in the seven-syllable [?a]-[da] series (where [?a] was the original or first syllable), there were98% [?a] responses to Syllable 3, but only 12% [?a] responses (88% [da] responses) to Syllable 5. Following the identification test, subjects listened to 180 repetitions of either the first or last syllable in the test series, and were again required to identify randomly presented syllables from the test series. A shift in the phoneme boundary toward the repeated (adapting) syllable was observed for 11 of the 12 repeated syllables. Repeated presentation of [?a], for example, resulted in fewer [?a] responses to syllables in the [?a]-[da] series, compared to performance on the previous identification test. Likewise, repeated listening to [da] resulted in a decrease in [da] responses. Adaptation was selective in that syllables near the phoneme boundary were most affected by the adapting syllable. A shift in the phoneme boundary was also observed for two different continua when the adapting stimulus contained an acoustic feature identical to syllables in the test series. Thus, selective adaptation was found along a [ma]-[ba] continuum following repeated presentation of [na] and following repeated presentation of nasal resonance removed from its syllable context. A second major result, observed in five different experiments, was an asymmetrical adaptation effect. A greater shift in the phoneme boundary was observed following repeated presentation of the first syllable in each series (e.g., [?a]) than for the final embedded syllable (e.g., [da]). The results were discussed in terms of two different models of-selective adaptation.     

Lateral asymmetry in the perceived sequence of speech and nonspeech stimuli

The task was to estimate the position where a click had been superimposed in a spoken sentence. Experiment 1 confirmed Fodor and Bever’s observation of an ear-asymmetry effect: the click is located earlier when it is presented to the left ear and the sentence to the right ear than with the opposite arrangement. In Experiment 2, combinations of monaural and binaural presentations were considered. They made it possible to eliminate interpretations which link the laterality effect to the fact of reaching or not reaching a particular ear and showed that the relevant factor is the relative position of the stimuli in acoustic space. Experiments 3 and 4 explored the relation between spatial separation and perceived sequence in greater detail. The relation involves a plateau: when the click comes to the left of the speech, it is preposed to a degree which depends on the amount of spatial separation; but, when it comes to the right of the speech, separation is irrelevant and the mean error is of the same order of magnitude as in a control condition without separation.
