Hidden profiles and the consensualization of social stereotypes: how information distribution affects stereotype content and sharedness

EUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 6 2003
Olivier Klein
We examined the impact of the distribution of information regarding social groups on the formation of shared stereotypes within triads in two studies. Three-person groups discussed which of three groups (A, B, and C) was the most able and the most sociable. In Study 1, some of the information about these three groups was available to all group members (shared) whereas the remainder was distributed among group members (unique). Based on the total profile, there was more evidence of group A being sociable and of group B being able than of A being able and B sociable. In Study 1 (n,=,58), sampling was manipulated as ,representative' (information in line with the overall differences was shared) or ,unrepresentative' (only information contradicting these differences was shared). In a third condition, all items of information were shared. Emerging stereotypes were directly influenced by sampling of information independently of the discussion. As well as this, the discussion consensualized initial stereotypes. In Study 2 (n,=,52), sampling was always unrepresentative and we manipulated the labels associated with the target groups in such a way that the stereotype associated with the label was either inconsistent or consistent with the overall differences between the target groups. In the inconsistent condition, participants were more likely to discuss information that violated stereotypical expectations, and to be less influenced by sampling as a result of discussion. Altogether, these findings suggest that information sampling directly affects the consensualization of social stereotypes. Copyright © 2003 John Wiley & Sons, Ltd. [source]

The adenine nucleotide translocase type 1 (ANT1): A new factor in mitochondrial disease

IUBMB LIFE, Issue 9 2005
J. Daniel Sharer
Abstract Mitochondrial disorders of oxidative phosphorylation (OXPHOS) comprise a growing list of potentially lethal diseases caused by mutations in either mitochondrial (mtDNA) or nuclear DNA (nDNA). Two such conditions, autosomal dominant progressive external ophthalmoplegia (adPEO) and Senger's Syndrome, are associated with dysfunction of the heart and muscle-specific isoform of the adenine nucleotide translocase (ANT1), a nDNA gene product that facilitates transport of ATP and ADP across the inner mitochondrial membrane. AdPEO is a mtDNA deletion disorder broadly characterized by pathology involving the eyes, skeletal muscle, and central nervous system. In addition to ANT1, mutations in at least two other nuclear genes, twinkle and POLG, have been shown to cause mtDNA destabilization associated with adPEO. Senger's syndrome is an autosomal recessive condition characterized by congenital heart defects, abnormalities of skeletal muscle mitochondria, cataracts, and elevated circulatory levels of lactic acid. This syndrome is associated with severe depletion of ANT1, which may be the result of an as yet unidentified ANT1-specific transcriptional or translational processing error. ANT1 has also been associated with a third condition, autosomal dominant facioscapulohumeral muscular dystrophy (FSHD), an adult onset disorder characterized by variable muscle weakness in the face, feet, shoulders, and hips. FSHD patients possess specific DNA deletions on chromosome 4, which appear to cause derepression of several nearby genes, including ANT1. Early development of FSHD may involve mitochondrial dysfunction and increased oxidative stress, possibly associated with overexpression of ANT1. IUBMB Life, 57: 607-614, 2005 [source]

Time course of vocal modulation during isolation in common marmosets (Callithrix jacchus)

AMERICAN JOURNAL OF PRIMATOLOGY, Issue 8 2010
Chieko Yamaguchi
Abstract Common marmosets vocalize phee calls as isolation calls, which seem to facilitate their reunion with family groups. To identify multiple acoustic properties with different time courses, we examined acoustic modulations of phees during different social contexts of isolation. Subject marmosets were totally isolated in one condition, were visually isolated and could exchange vocalizations in another condition, and were visually isolated and subsequently totally isolated in a third condition. We recorded 6,035 phees of 10 male,female marmoset pairs and conducted acoustic analysis. The marmosets frequently vocalized phees that were temporally elongated and louder during isolation, with varying time courses of these changes in acoustic parameters. The vocal rates and sound levels of the phees increased as soon as the marmosets saw their pair mates being taken away, and then gradually calmed down. The phee duration was longer in conditions during which there were no vocal responses from their pair mates. Louder vocalizations are conspicuous and seem to be effective for long-distance transmission, whereas shorter call duration during vocal exchanges might avoid possible vocal overlap between mates.

Deficits of temporal discrimination in dystonia are independent from the spatial distance between the loci of tactile stimulation

MOVEMENT DISORDERS, Issue 2 2002
Michele Tinazzi MD
Abstract To assess whether spatial variables influence deficits of temporal somesthetic discrimination in dystonic patients, 10 patients with idiopathic dystonia and 12 healthy controls were tested with pairs of non-noxious electrical stimuli separated by different time intervals. Stimuli were delivered: (1) to the pad of the index finger (same-point condition), (2) to the pad and to the base of the index finger (same-finger condition), and (3) to the pad of the index and ring fingers (different-finger condition). Subjects were asked to report whether they perceived single or double stimuli in the first condition and synchronous or asynchronous stimuli in the second and third conditions. Somesthetic temporal discrimination thresholds (STDTs) were obtained by computing the shortest time interval at which stimuli, applied to the left or the right hand, were perceived as separate in the first condition or asynchronous in the second and third conditions. STDTs were significantly higher in dystonic patients than controls in all three conditions. In both dystonia patients and controls, STDTs resulted highest in conditions whereby stimuli were maximally separated in space. Results extend current knowledge of deficits of somesthetic temporal discrimination in dystonia by showing that temporal deficits are not influenced by spatial variables. © 2002 Movement Disorder Society.

Capital and the Lagos Presidency: Business as Usual?

BULLETIN OF LATIN AMERICAN RESEARCH, Issue 3 2002
Eduardo Silva
Business-state relations in Chile's new democracy had been relatively tension-free for the first two governments of the centre-left Concertación de Partidos por la Democracia. However, during the first two years of the third Concertación administration, under the presidency of Ricardo Lagos, the relationship soured dramatically. At first glance, an ideological shift in the ruling coalition's centre of gravity would seem to explain the change in business-state relations. During the first two governments more conservative factions of the centrist Christian Democratic party had controlled the Concertación. Lagos, on the other hand, represented the left pole of the coalition and his socialist credentials brought the long shadow of the past on his presidency. This, however is an insufficient cause, three additional conditions must also be taken into account. The first one considers changes in the institutional and economic context that eroded the private sector's confidence in the Concertación's commitment to maintain the free-market socioeconomic model imposed under military rule. The second and third conditions are a decline in the electoral fortunes of the Concertación in favour of conservative parties and a shift in power relations among employers' associations towards more confrontational factions.
