Concerning the Sociological Analysis of Technological Innovation

Des observations paradoxales faites pendant les phases d'une recherche sur les salaires dans des entreprises industrielles françaises, nous ont conduit àénoncer que leur situation est le résultat de la présence de trois modèles de valorisation validés simultanément. On a observé que l'innovation technologique est une source de modification de l'équilibre des salaires. L'approche en termes de modéle de valorisation aide à comprendre le processus de régulation qui peut être remarqué après l'apparition de ce type d'innovation. Le processus qui a conduit à un nouvel équilibre des salaires des spécialistes de l'informatique est offert ici en exemple.
Some paradoxical observations made during a research study on wages in French industrial firms have led us to propose that the state of wages is the result of the presence of three simultaneously legitimate models of validation. Technological innovation is a source of modification of the equilibrium observed at any moment with regard to wages. The approach in terms of models of validation helps the understanding of the regulation process which may be observed after the appearance of such an innovation. The process which has led to a new equilibrium of the wages of specialists in data processing is offered as an example.     

Does Attention Modulate the Perception of Luminance Changes?

In a previous study assessing the modulation of visual processing by attention, Bonnel, Possami, and Schmitt showed that, when discriminating line-length, subjects precisely shared processing resources between two pairs of lines presented to the left and right of fixation. In a close replication requiring the detection of luminance increments instead of line-length differences, subjects were unable to follow the instructions and to allocate attention differentially, thus supporting the claim that light detection is fundamentally different from shape discrimination. In a subsequent experiment, we tested and rejected the possibility that luminance perception was not open to modulation by attention due to its physical nature. Replacing brightness detection by brightness identification allowed voluntary control on the quality of processing to be evidenced. The similarity between the latter results and the data from line-length discrimination suggests that task requirements may be crucial in determining the distribution of attention.     

Septal damage in infant and adult rats: Effects on activity,emotionality, and muricide

Septal lesions produced signs of increased emotionality in the adult rat, the septal syndrome (hyperresponsiveness to handling; in the open field: decreased rearing and ambulation activity, increased defecation, deficient habituation) being more or less complete and more or less marked depending on the age at which the lesion was performed (7 days or 3 months), the extent of the lesion (restricted to the septum or extending to more ventrally located structures) and the environmental conditions in which the animals were reared (in groups or in isolation). All septal lesions provoked a similar and significant increase in the probability of occurrence of mouse-killing behavior, irrespective of age of operation, extent of lesion and kind of rearing environment. In a 24-hour actography starting at 11:30 a.m., the rats septalectomized at adult age were less active than controls during the initial period, while all septals were markedly more active than controls during the night period. Early septal lesions only transiently disrupted weight gain. The results obtained point to complex interactions between the effects of early brain damage and environmental conditions.     

On the nature of mental models of conditional: The case of If,If then,and Only if

It has recently been reported that forward inferences from if p then q sentences (i.e., from antecedent to consequent) were faster than backward inferences from consequent to antecedent (Barrouillet, Grosset, & Lecas, 2000). The standard mental model theory assumes that this directionality effect is a figural effect due to the order the information enters working memory, whereas we claim that it results from the nature of the mental models that represent oriented relations from hypothetical values introduced by the word If. We tested these hypotheses in an experiment in which adult participants evaluated conditional syllogisms from either if p then q, p only if q, or p if q statements. Contrary to the predictions resulting from the standard theory, the three forms of the conditional provoked a reversed directionality effect and denial inferences took longer to endorse than affirmative inferences for all the forms of conditionals. We argue from these results that mental models of the conditional represent oriented relations instead of mere co-occurrences between events.     

Psychological and neurological predictors of abusive supervision

Although the negative effects of abusive supervision are well documented, less is known about the individual differences that drive supervisors to be abusive. We use a self‐control perspective to understand the unique roles of both psychological and neurological characteristics of supervisors in the prediction of abusive behavior. Specifically, we find a positive relationship between narcissism and abusive supervision, whereas political skill and intrinsic neurological connectivity in executive control regions of the brain negatively relate to abusive supervision. Our results further show that the relationship between narcissism and abusive supervision diminishes for those who are strong in terms of political skill. In addition, neurological executive control moderates the relationship between political skill and abusive behavior. When connectivity in executive control regions of the brain is lower, political skill becomes a more important factor in reducing the display of abusive behavior. Overall, we demonstrate how combinations of characteristics (both psychological and neurological) can provide a more in‐depth understanding of the emergence of abusive supervision.     

The Use of the Social Cognition and Object Relations Scale in a Primary Care Setting

Research has indicated that as many as 10% to 15% of primary care patients have symptoms that are not well explained medically. These patients could be labeled as “somatizers.” This study assessed the extent to which underlying psychological characteristics contribute to a person's level of somatization and service utilization. The Social Cognition and Object Relations Scale–Global Rating Method (SCORS–G; Stein, Hilsenroth, Slavin-Mulford, & Pinsker, 2011; Westen, 1995) was used to rate early memory narratives of 100 patients in a suburban primary care setting. Using principal axis factoring, the SCORS–G was divided into 2 components and these components (cognitive and affective) were used in subsequent analyses. The affective component was significantly negatively correlated with 2 measures of somatization and positively related to physician ratings of global health. The affective component also showed a trend toward significance on overnight hospital stays and patient-rated health. The cognitive component showed a trend toward significance with both measures of somatization, but it was not correlated with other measures of health. This study demonstrates the value of assessing underlying processes (via SCORS–G ratings of early memory narratives) that contribute to increased rates of somatization and health care utilization. Clinical implications for the relationship between affect and physical health are explored.
