Affective divergence: Automatic responses to others' emotions depend on group membership.

Extant research suggests that targets' emotion expressions automatically evoke similar affect in perceivers. The authors hypothesized that the automatic impact of emotion expressions depends on group membership. In Experiments 1 and 2, an affective priming paradigm was used to measure immediate and preconscious affective responses to same-race or other-race emotion expressions. In Experiment 3, spontaneous vocal affect was measured as participants described the emotions of an ingroup or outgroup sports team fan. In these experiments, immediate and spontaneous affective responses depended on whether the emotional target was ingroup or outgroup. Positive responses to fear expressions and negative responses to joy expressions were observed in outgroup perceivers, relative to ingroup perceivers. In Experiments 4 and 5, discrete emotional responses were examined. In a lexical decision task (Experiment 4), facial expressions of joy elicited fear in outgroup perceivers, relative to ingroup perceivers. In contrast, facial expressions of fear elicited less fear in outgroup than in ingroup perceivers. In Experiment 5, felt dominance mediated emotional responses to ingroup and outgroup vocal emotion. These data support a signal-value model in which emotion expressions signal environmental conditions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Influence of In3＋ ions concentration on spectroscopic properties of Ho：LiNbO3 crystals

In:Ho:LiNbO3 crystals doped with various concentrations of In3+(0, 1 mol.%, 3 mol.%, 5 mol.%), fixed concentrations of Ho3+ (1 mol.%) were grown by Czochralski method. The X-ray powder diffraction, infrared and UV-visible absorption spectra were measured and modified. Judd-Ofelt approach was employed to study the effect of In doping on spectroscopic properties of Ho:LiNbO3 crystals. In concentrations in crystals were analyzed by an inductively coupled plasma optical emission spectrometry (ICP-OE/MS). For In (3 mol.%):Ho (1 mol.%):LiNbO3 crystal, the obtained intensity parameters were: Ω2=9.6563, Ω4=4.2195, Ω6=14.1526. The results showed that the Ω2 and Ω6 parameters increased with the increase of In3+ concentration. When the In doping concentration was up to 5 mol.%, Ω2 and Ω6 suddenly decreased. In2O3 incorporation had a strong effect on the radiative lifetime, but had less influence on fluorescence branching ratios. The effective distribution coefficient of In3+ in In:Ho:LiNbO3 crystals was less than 1 and increased with increasing concentration of In3+ in the melt.     

Kikuchi-Fujimoto disease: benign cause of fever and lymphadenopathy

The purpose of this study was to determine the advantages and disadvantages of several techniques for performing the pneumoperitoneum. We studied 75 patients divided into three groups of 25 each. In the first group, we used the Veress needle technique in the umbilicus. In the second group, the insertion was in the upper left quadrant, and in the third group the insertion was direct with a disposable trocar in the umbilicus without pneumoperitoneum. In the first group, we made 32 attempts, and the time varied from 8 to 35 min. In the second group we made 28 attempts and the time was from 3 to 6 min. In both we had complications. In the third group, we made 25 direct insertions without complications, and the time was from 45 s to 3 min.     

Differential in vivo effects of alpha-naphthoflavone and beta-naphthoflavone on CYP1A1 and CYP2E1 in rat liver, lung, heart, and kidney

Tenascin is a large extracellular matrix glycoprotein expressed in neural and non-neural tissues. In the central nervous system, tenascin is synthesized by astrocytes during development and wound healing, forming barriers and affecting neurite outgrowth. In this study we examined tenascin expression in optic nerve heads of normal and glaucomatous eyes and found that there is upregulation of tenascin mRNA and protein in reactive astrocytes from human glaucomatous optic nerve heads compared to normal age-matched controls. In the prelaminar region there was a band of tenascin immunoreactivity around the blood vessels of glaucomatous, but not in normal eyes. However, tenascin mRNA was only localized to astrocytes, suggesting that astrocytes are the cellular source of tenascin. In the lamina cribrosa, tenascin immunoreactivity and gene expression were localized to astrocytes in the cribriform plates and inside the nerve bundles. In the post-lamina region, tenascin immunoreactivity and gene expression were localized to astrocytes lining the pial septum immediately adjacent to the lamina cribrosa. In normal optic nerve heads, tenascin expression at the mRNA and protein levels was confined to clusters of astrocytes at the level of Bruch's membrane in the prelaminar optic nerve head. In glaucoma, enhanced expression of tenascin may be protective to the axons of the retinal ganglion cells by providing a barrier for humoral and/or blood-borne factors that may cause further neural damage. However, the precise role of tenascin in glaucomatous optic neuropathy is not yet elucidated.     

Negative Affects Deriving From the Behavioral Approach System.

Does the behavioral approach system (BAS) relate to the experience of any negative affects, or are all negative affects tied to the behavioral inhibition system (BIS)? In Study 1, self-reported Fun Seeking predicted reports of greater frustration and sadness after frustrative nonreward. In Study 2, self-reported Reward Responsiveness predicted reports of greater anger in response to scenarios. In Study 3, self-reported Drive predicted reports of greater anger after the terrorist attacks of September 11, 2001. In no case did BIS sensitivity contribute uniquely to these affects, though BIS predicted nervousness in Study 2 and fear in Study 3. Discussion focuses on the role of frustration and anger in effortful pursuit of goals and depressed affect in disengagement from goals.

Beyond event segmentation: Spatial- and social-cognitive processes in verb-to-action mapping.

The present article investigates spatial- and social-cognitive processes in toddlers' mapping of concepts to real-world events. In 2 studies we explore how event segmentation might lay the groundwork for extracting actions from the event stream and conceptually mapping novel verbs to these actions. In Study 1, toddlers demonstrated the ability to segment a novel multiaction event by selecting a single action for behavioral reenactment when prompted. In Study 2, a single action embedded in the event sequence was specified as the referent for a novel verb through cues to support intentional inference. As in Study 1, toddlers spontaneously segmented the sequence. In addition, they mapped a novel label to the embedded action specified by the novel label and intentional cues. These data are consistent with current thinking that suggests a convergence of spatial and social cognition in verb learning. In the present research, toddlers built upon event segmentation skills and used intentional inference when mapping verbs to actions embedded in the motion stream.

Unspoken cultural influence: Exposure to and influence of nonverbal bias.

The authors examined the extent to which nonverbal behavior contributes to culturally shared attitudes and beliefs. In Study 1, especially slim women elicited especially positive nonverbal behaviors in popular television shows. In Study 2, exposure to this nonverbal bias caused women to have especially slim cultural and personal ideals of female beauty and to have especially positive attitudes toward slim women. In Study 3, individual differences in exposure to such nonverbal bias accounted for substantial variance in pro-slim attitudes, anti-fat attitudes, and personal ideals of beauty, even after controlling for several third variables. In Study 4, regional differences in exposure to nonverbal bias accounted for substantial variance in regional unhealthy dieting behaviors, even after controlling for several third variables.

Distinguishing Age Differences in Knowledge, Strategy Use, and Confidence During Strategic Skill Acquisition.

The authors examined how age differences in strategy selection are related to associative learning deficits and metacognitive variables, including memory ability confidence. In Experiment 1, increases in memory reliance for performance of the noun-pair lookup task were compared with increases in noun-pair memory ability. In Experiment 2, memory reliance was assessed for noun pairs memorized prior to the task. In each experiment, older adults manifested a substantial delay in transition to a retrieval-based strategy despite comparable noun-pair knowledge. In Experiment 3, young and older adults reported comparable confidence ratings for the accuracy of each memory probe response. However, older adults reported lower confidence in their general ability to use the memory retrieval strategy, which correlated with avoidance of the retrieval strategy.
