PET and P300 Relationships in Early Alzheimer\u27s Disease

The P300 (P3) wave of the auditory brain event-related potential was investigated in patients with probable Alzheimer\u27s disease to determine whether P300 latency discriminated these patients from controls and whether prolonged P300 latency correlated with rates of brain glucose metabolism as measured by Positron Emission Tomography. P300 latency was prolonged by more than 1.5 standard deviations from age expectancy in 14 of 18 patients, but none of 17 controls. In these subjects P300 latency was shown to be inversely correlated with relative metabolic rates of parietal and, to a lesser extent, temporal and frontal association areas, but not with subcortical areas

A Cross-Cultural Study of Justice Sensitivity and Its Consequences for Cooperation

In Western samples, individuals differ systematically in the importance they assign to matters of justice and injustice, and dispositional Justice Sensitivity can be differentiated according to the perspectives of victim, observer, beneficiary, and perpetrator. In a cross-cultural comparison between the Philippines, Germany, and Australia (N ¼ 677 students), we investigated whether Justice Sensitivity can be equivalently described by these four perspectives, whether measurement instruments have invariant psychometric properties, and whether the psychological relevance of the Justice Sensitivity perspectives for cooperation behavior differs between these cultural contexts. The results of multigroup confirmatory factor analyses support weak measurement invariance and invariant associations between Justice Sensitivity perspectives and trust game decisions. Across cultures, victim sensitivity predicted reluctance to cooperate under threat of exploitation, and observer, beneficiary, and perpetrator sensitivities predicted cooperation under temptation. Our study extends insight into Justice Sensitivity to underresearched cultural contexts of urban and rural Philippines
