Quels enjeux pour les soins bucco-dentaires sous anesthésie générale chez les adultes ?

Common dental acts sometimes require to be performed under general anesthesia. This article describes the development of an adult consultation for dental care under general anesthesia at hospital Henri-Mondor in Créteil group. Forty-two people received dental care under general anesthesia during the year 2015 at Henri-Mondor hospital. Thirty-eight percent were aged 21 to 30 years. The main reason for using general anesthesia phobias 56%. The second reason, with 31%, is on disability. Among the type of intervention, 61% represent extractions of permanent teeth. However, our study shows that the indication of general anesthesia must be asked as a last resort. Other alternative techniques exist and must be offered an upstream. General anesthesia tends to grow and be part of a comprehensive treatment of certain categories of patients. General anesthesia comfort remains prohibited.     

On the anatomy of social engineering attacks—A literature‐based dissection of successful attacks

The aim of this study was to explore the extent to which persuasion principles are used in successful social engineering attacks. Seventy‐four scenarios were extracted from 4 books on social engineering (written by social engineers) and analysed. Each scenario was split into attack steps, containing single interactions between offender and target. For each attack step, persuasion principles were identified. The main findings are that (a) persuasion principles are often used in social engineering attacks, (b) authority (1 of the 6 persuasion principles) is used considerably more often than others, and (c) single‐principle attack steps occur more often than multiple‐principle ones. The social engineers identified in the scenarios more often used persuasion principles compared to other social influences. The scenario analysis illustrates how to exploit the human element in security. The findings support the view that security mechanisms should include not only technical but also social countermeasures.     

Optimism and Mental Health in Adolescence: a Prospective Validation Study of the Dutch Life-Orientation Test-Revised (LOT-R-A) for Adolescents

The study aimed to examine the psychometric properties of the Dutch Life Orientation Test-Revised for Adolescents (LOT-R-A), a self-report questionnaire assessing dispositional optimism, and to evaluate the two-factor structure (optimism, pessimism). The LOT-R-A and the questionnaires measuring well-being (MHC-SF-A) and psychological problems (SDQ) were completed by 459 Dutch adolescents (178 boys and 281 girls) between the ages of 11 and 18 years at baseline and 281 adolescents at a four-week follow-up. The results confirmed the two-factor structure (optimism, pessimism) of the LOT-R-A. The findings provided evidence of internal consistency of scores ranging from low to good, and evidence of good test-retest reliability of scores. Further, scores of optimism were cross-sectionally positively associated with scores of positive emotions and well-being and negatively with scores of psychological problems and negative emotions, providing evidence of convergent and divergent validity of optimism scores with emotions, well-being, and psychological problems. Lastly, scores of optimism were prospectively positively associated with scores of well-being and negatively with scores of psychological problems, providing evidence of criterion validity of optimism scores with well-being and psychological problems. Based on these findings it can be concluded that the LOT-R-A is a valid instrument to examine optimism among adolescents. Future research can help to elucidate the role of optimism in mental health interventions and can gather knowledge on how these interventions can be refined to optimally cultivate optimism during the developmental period of adolescence.     

Dominance as Expressed and Inferred Through Speaking Time

Differences in speaking time during a group interaction are hypothesized to reflect differences in individual dominance. In order to test this assumption and to identify potential moderator variables influencing the strength of the predicted association, a meta‐analysis was conducted. Whether speaking time is used to convey dominance to the same extent that it is used in inferring dominance was tested by contrasting studies concerned with dominance expressed in speaking time with studies of inferred dominance based on speaking time. Overall, and for the investigated subcategories of studies, the relationship between dominance and speaking time was significant. The strength of the associations, however, differed considerably due to the influence of moderator variables. The results showed that inferred dominance studies showed stronger associations between speaking time and dominance as opposed to the expressed dominance studies. Additionally, if dominance was expressed due to dominance‐role assignments, the association between speaking time and dominance was stronger than if individuals with different levels of trait dominance interacted. For men, the association between speaking time and dominance was stronger than for women, and same‐gender groups showed stronger associations than opposite‐gender groups. Also, increasing group size intensified the strength of the association linearly.     

Affective-Evaluative Learning in Humans: A Form of Associative Learning or Only an Artifact?

The status of evaluative conditioning (EC) as a distinct form of associative learning was called in question by Field and Davey (1997, 1998, 1999), who argued that in the typical visual EC paradigm, nonassociative visual concept learning is responsible for the evaluative changes observed. Especially, the use of only within-subject control conditions instead of independent control groups was criticized. The present three experiments show (a) that EC effects can be demonstrated within another sensory modality than visual perception and (b) that EC effects are demonstrable in a between-subject design (including a successful replication attempt). A further result was that these EC effects do not require participants' conscious awareness. The data provide no support for an artifactual account of EC but suggest an interpretation of EC as a form of associative learning.     

Effects of sex role stereotyping among European American students on domestic violence culpability attributions

Effects of European American students' sex role stereotyping and domestic violence participants' race and relationship intimacy were examined for culpability attributions. In addition to a man's responsibility rating and a sentencing measure, five factors were identified from the dependent measures; these were Sympathy with Man, Incident as Abusive, Generalness of Incident, Seriousness of Incident, and Man as Abuser. Results indicated that sex role stereotyping was influential in culpability attributions, as those with traditional orientations showed a favorable bias toward the man, particularly a married man. Traditionalists provided a shorter sentence for the man and thought the incident less abusive when the woman was African American, in comparison to egalitarians. Both egalitarians and traditionalists expressed more sympathy toward the man when the woman was African American and married. Although we had anticipated higher culpability ratings for women involved in interracial relationships, we found that the European American man was thought less responsible when the woman was African American, but no differences emerged when the woman was European American. It is suggested future research examine the specific content of various stereotypic subtypes of actors involved in domestic violence and how these stereotypic subtypes bias culpability attributions.Appreciation is extended to an anonymous reviewer for helpful comments on an earlier version of this article.Portions of this research were presented at the 1994 biennial meeting of the American Psychology-Law Society, Santa Fe, NM.     

When visual search functions look like item recognition functions

Visual search data were collected from six Ss on three target set sizes on each of 30 days. Error level was low, and items assigned to memory sets were nonnested and changed from session tosession. For each S. the same item sometimes required a positive and sometimes a negative response (response inconsistency). Combining data over Ss and over successive 6-day blocks, visual search rates as a function of target set size were found to be linear for each of the five 6-day blocks. The slopes of the above functions (memory search time) did not differ significantly over the final four 6-day blocks, and averaged approximately.500 sec per six-character item. These results are qualitatively very similar to results obtained from item recognition studies when error level, memory set structure, degree of response’_ consistency, and practice are handled in the same way in that task. The significantly lower slope obtained on the first 6-day block is shown to be consistent with a speed-accuracy trade off interpretation when error rate is expressed per unit of processing time (percent errors/set size). Over the final three 6-day blocks, where all important parameters ofthe data were highly stable, the intercepts of the memory search functions were found to closely approximate zero, averaging .0068 sec. From this finding, along with the finding that the memory search functions are linear, it is inferred that visual search time is determined entirely by memory search time, or by memory search time and other processes which increase linearly with set size, under the conditions of this experiment. The estimate of memory search time (approximately 83 msec/character) obtained using this visual search procedure is much slower than that obtained using the item recognition procedure (approximately 35\2-40 msec/character). An explanation for this difference is proposed.     

THE INFLUENCE OF AUDITORY STIMULUS INTENSITY ON APPARENT DURATION

B erglund , B., B erglund , U., E kman , G. & F rankenhaeuser , M. The influence of auditory stimulus intensity on apparent duration. Scand J. Psychol ., 1969, 10 21–26.— apparent duration of an auditory signal of 1000 C/S was measured by the method of magnitude estimation. Ten different stimulus intensities ranging from 57 to 104 dB were used in combination with three different durations: 50, 250, and 500 msec. The results showed that the apparent duration of the signal grew as a logarithmic function of stimulus intensity. These results are consistent with the hypothesis relating apparent duration to activation level as well as with results of similar experiments involving electrical and vibrotactile stimulation.     

Psychophysiological reactions to understimulation and overstimulation

Catecholamine output, heart rate, and performance efficiency were examined in 28 Ss during two contrasting stimulus conditions, one of understimulation, and one of overstimulation. During understimulation the subject spent 3 hr performing a vigilance task, and during overstimulation he was exposed for the same time period to a complex sensorimotor test. Both understimulation and overstimulation produced a significant increase of adrenaline and noradrenaline release as compared with a control condition involving a medium amount of stimulation. Subjects who excreted relatively more adrenaline performed significantly better during understimulation, whereas subjects with relatively lower excretion rates of adrenaline tended to perform better under overstimulation. When performance efficiency was related to heart rate it was shown that high-heart rate subjects performed better during understimulation, while low-heart rate subjects performed better during overstimulation.
