Subcutaneous injection of dilute formalin induces pain in humans and behaviors indicative of pain in animals. The formalin test, which is based on these observations, is now widely used as a model of pain produced by tissue injury, but the neural mechanisms of pain and analgesia in this test have not been identified. Rats with transections of the brain rostral or caudal to the pons show behavioral reactions to formalin similar to those of normal rats, although the temporary abatement of pain 10-15 min after formalin is absent in transected animals. Doses of morphine that suppress the behavioral response to formalin in normal rats are not antinociceptive in the formalin test in decerebrate rats although sedation, catalepsy and inhibition of the tail-flick reflex still occur. These results suggest that the response to formalin is organized in the brain stem but the antinociceptive effect of morphine in this test is mediated by the diencephalon or forebrain.

Two self-report experiments examined how religiosity affects attributions made for a target person's death. Online adults (Study 1, N = 427) and undergraduate students (Study 2, N = 326) read about Chris who had a heart attack, used religious or health behaviors, and lived or died. Participants made attributions to Chris and God (both studies), and reported their emotions (Study 2). Participants made more attributions to Chris when he lived than when he died, but only when he used health behaviors. The highly religious made more attributions to God, but not when Chris used religious behaviors and died (the God-serving bias); they reported the most positive emotions when Chris lived after using religious behaviors (the Hallelujah effect). Directions for future research in terms of implicit religious beliefs and normative evaluations of religion are discussed.

In this study, we tested the following hypotheses concerning cultural value orientations as predictors of accommodation among heterosexual relationships in Jamaica: (a) Individuals' Group Orientation will be a significant positive predictor of Accommodation toward opposite-sex relationship partners, whereas (b) individuals' Self Orientation will not be significantly related to Accommodation toward opposite-sex relationship partners. A total of 287 individuals (44 males, 233 females, and 10 unspecified) participated in this study. Results of structural equation analyses of data for Blacks and persons of other races indicated that, contrary to our hypotheses, individuals' Self Orientation was a significant negative predictor of Accommodation, and individuals' Group Orientation was a nonsignificant positive predictor of Accommodation. Results of this study differ markedly from results previously obtained with predominantly White samples of heterosexuals and gays in the United States. Implications for the study of personal relationship processes in Jamaica and other predominantly Black nations are discussed.
