Individual differences in motivated social cognition: The case of self-serving information processing

Three experiments examined the hypothesis that people show consistency in motivated social cognitive processing across self-serving domains. Consistent with this hypothesis, Experiment 1 revealed that people who rated a task at which they succeeded as more important than a task at which they failed also cheated on a series of math problems, but only when they could rationalize their cheating as unintentional. Experiment 2 replicated this finding and demonstrated that a self-report measure of self-deception did not predict this rationalized cheating. Experiment 3 replicated Experiments 1 and 2 and ruled out several alternative explanations. These experiments suggest that people who show motivated processing in ego-protective domains also show motivated processing in extrinsic domains. These experiments also introduce a new measurement procedure for differentiating between intentional versus rationalized cheating.

The usefulness of acetic acid wash and chemiluminescent illumination (Vizilite) in the visualization of oral mucosal white lesions

A diligent and careful examination of the mouth and oral structures has been historically deficient in revealing premalignant and malignant oral lesions. Conventional screening practice for oral neoplastic lesions involves visual scrutiny of the oral tissues with the naked eye under projected incandescent or halogen illumination. Visualization is the principal strategy used to find patients with lesions at risk for malignant transformation; hence, any procedure which highlights neoplastic lesions should aid the clinician. This pilot study examined the usefulness of acetic acid wash and chemiluminescent light (Vizilite) in enhancing visualization of oral mucosal white lesions, and its ability to highlight malignant and potentially malignant lesions. Fifty five patients referred for assessment of a white lesion, were prospectively screened with Vizilite, and an incisional biopsy performed for a definitive diagnosis. The age, sex, and smoking status of all patients were recorded, and all lesions were photographed. The visibility, location, size, border, and presence of satellite lesions, were also recorded. The Vizilite tool enhanced intraoral visualization of 26 white lesions, but it could not distinguish between epithelial hyperplasia, dysplasia, or carcinoma. Indeed, all lesions appeared ‘‘aceto-white’’, regardless of the definitive diagnosis. On one occasion, Vizilite aided in the identification of a satellite lesion that was not observed by routine visual inspection. Vizilite appears to be a useful visualization tool, but it does not aid in the identification of malignant and potentially malignant lesions of the oral mucosa.

Mild head injury and speed of information processing: A prospective study of professional rugby league players

The sensitivity of several short tests of speed of information processing to the effects of mild head injury in rugby league football was investigated. The measures used were the Symbol Digit Modalities Test, the Digit Symbol Substitution Test, and the Speed of Comprehension Test. Two studies were conducted, the first to examine the effect of practice, the second to determine sensitivity to cognitive impairment immediately following injury. The first study established alternate form equivalence and demonstrated that performance on the Speed of Comprehension and Digit Symbol Substitution tests improved with practice, whereas the Symbol Digit Modalities test remained stable. A second study of 10 players who subsequently sustained mild head injuries showed that measures of speed of information processing were sensitive to impairment in the postacute phase, whereas an untimed task of word recognition (Spot-the-Word) was not. Speed of Comprehension was more sensitive to postinjury impairment than either the Digit Symbol Substitution or Symbol Digit Modalities tests. A repeated baseline assessment before injury using the higher score to reflect a player's potential, allowed measurement of impaired performance on sensitive tests.

Geometric and electronic information from the spectroscopy of six-coordinate copper(II) compounds

The ground and excited state geometry of the six-coordinate copper(II) ion is examined in detail using the CuF64- and Cu(H2O)(6)(2+) complexes as examples. A variety of spectroscopic techniques are used to illustrate the relations between the geometric and electronic properties of these complexes through the characterization of their potential energy surfaces.
