Hyperlexia as a variant of developmental language disorder

Memory and associative reasoning skills of 10 hyperlexic children are examined. The results suggest superior visual and isolated auditory memory skills along with impaired associative language ability. The results are discussed in relation to various theories of hyperlexia.     

The determination of optimal exposure to phobic stimuli in flooding therapy

The present study compared the value of various criteria for determining exposure duration to phobic stimuli in flooding therapy. Results indicated that basing exposure termination on a return to resting ranges of HR was not effective in increasing approach behavior, whereas basing termination on observer's judgements was quite effective. Employing self-reported anxiety reduction as the termination criterion was no more effective than using either the HR criterion or a procedure that combined all three criteria (HR, self-report, and observer's judgements). Self-reported fear data showed similar trends with the HR criterion again failing to produce any greater benefits than control procedures. Nine-weeks follow-up indicated a persistence of the behavioral changes with some loss of the gains in subjective anxiety, and a reduction in the differences between groups.     

Differential acquisition of conditioned suppression in rats with increased and decreased luminance levels as CS + s

Using a conditioned suppression procedure, it was demonstrated that suppression of responding was substantially enhanced when the CS signaling the occurrence of shock was an increment in luminance level (bright CS), relative to an equivalent decrement in luminance level serving as a signal for shock (dim CS). The results of a pseudoconditioning control procedure illustrated that the differential effectiveness of the bright and dim CSs was dependent upon explicit CS-US pairings. The bright and dim stimuli were found to produce equivalent rates of conditioning when they were used to signal the availability of reinforcing stimuli in an appetitive discrimination procedure. The interpretation considered to be most consistent with the data is associative in nature; rats may be brought into the experimental setting prepared to associate bright light with danger and contraprepared to associate dim light with danger.     

The perception of alternated speech

When speech is rapidly alternated between the two ears, intelligibility declines as rates approach 3–5 switching cycles/sec and then paradoxically returns to a good level beyond that point. The present study examines previous explanations of the phenomenon by comparing intelligibility of alternated speech with that for presentation of an interrupted message to a single ear. Results favor one of two possible explanations, and a theoretical model to account for the effect is proposed.     

Auditory perception of speech and speech sounds in recent and recovered cases of aphasia

Auditory perception of speech and speech sounds was examined in three groups of patients with cerebral damage in the dominant hemisphere. Two groups consisted of brain-injured war veterans, one group of patients with high-frequency hearing loss and the other, a group of patients with a flat hearing loss. The third group consisted of patients with recent cerebral infarcts due to vascular occlusion of the middle cerebral and internal carotid artery. Word and phoneme discrimination as well as phoneme confusions in incorrect responses were analyzed from conventional speech audiometry tests with bisyllabic Finnish words fed close to the speech reception threshold of the patient. The results were compared with those of a control group with no cerebral disorders and normal hearing. The speech discrimination scores of veterans with high-frequency hearing loss and patients with recent cerebral infarcts were some 15–20% lower than those of controls or veterans with flat hearing loss. Speech sound feature discrimination, analyzed in terms of place of articulation and distinctive features, was distorted especially in cases of recent cerebral infarcts, whereas general information transmission of phonemes was more impaired in patients with high-frequency hearing loss.     

The interaction of locus of control expectancies and providing purpose on children's motivation

Children differing in locus of control orientation (internals, mediums, and externals' were administered an extended coding task following either a fictional rationale for the study (purpose incentive statement) or no purpose. As predicted, externals' performance under no purpose was significantly poorer and their rated interest in the task was significantly less favorable than those of internals. Also as predicted, these differences were nullified under the purpose incentive condition. The findings extend Lefcourt's (1967) suggestion that cue explication is important for externals to include external children, and support the position (Mischel, 1973; Rotter, 1975) that personality variables are increasingly important as a function of greater situational ambiguity. Implications of these findings for education and child-rearing are discussed.     

Valorisation de la recherche en santé humaine et protection des données à l’ère du numérique

Medical research collects a huge number of medical data sheltered in Data Centers. An European regulation rule (GDRP) or General Data Protection Regulation aims to give an ethic frame to protect personal data and delegate responsability to citizens.     

Les pratiques professionnelles au cœur de la crise dans la gestion de l’urgent : l’exemple de la crise du COVID-19

Our organisations have been severely shaken by the COVID-19 pandemic and the world of work has not been spared. Only essential activities continued in order to maintain a minimum level of functioning, just like in hospitals or in local authorities. During the first five months of the crisis in 2020 (from March to July), 34 interviews were conducted in these two public service entities in order to examine the management of urgent matters in the light of “activity” and at the heart of the crisis. The results show that while the emergency is mainly managed by an improvisation activity based on the intuition of the actors in the field, the crisis is managed by governance in a rational manner leading to the drafting of procedures after the event. This crisis situation pushed organisations to reconfigure themselves in an emergency, allowing the development of new professional practices. The strategies of damage control and proceduralization will be discussed. Perspectives are opened on the questions of training for these crisis situations against a background of developing presumption of ignorance.
