What analytic metaphysics can do for scientific metaphysics

The apparent chasm between two camps in metaphysics, analytic metaphysics and scientific metaphysics, is well recognized. I argue that the relationship between them is not necessarily a rivalry; a division of labour that resembles the relationship between pure mathematics and science is possible. As a case study, I look into the metaphysical underdetermination argument for ontic structural realism, a well-known position in scientific metaphysics, together with an argument for the position in analytic metaphysics known as ontological nihilism. I argue that we can ascribe the same schema to both arguments, which indicates that analytic metaphysics can offer an abstract model that scientific metaphysics may find useful.     

“You're overreacting!”: The ambiguity of Asian American microaggressions delegitimizes collective action

Asian Americans are lauded as the model minority who are intelligent and industrious. Simultaneously, they are deemed as perpetual foreigners. The current research examines how racial microaggressions expressed by a White American source toward an Asian American target affect perceptions of the perpetrator and target. White Americans and Asian Americans read about an interaction between two college students, where the racial microaggression made was either an ambiguous expression of the model minority myth (MMM; all studies), an ambiguous perpetual foreigner stereotype (all studies), an unambiguous MMM (all studies), or no racial bias (Studies 2 and 3). Findings indicate that both Whites and Asian Americans respond differently—when exposed to the aforementioned conditions—regarding perceived racism of the White perpetrator and appropriateness of response by the Asian American target; however, they respond similarly regarding perceived legitimacy of collective action by the target. Nevertheless, Whites and Asian Americans deemed the ambiguous microaggression against the target as a model minority not racist relative to unambiguous MMM. Our findings show that ambiguous forms of bias toward Asian Americans go “under the radar” of both Whites and Asian Americans as being racist and contribute to the maintenance of the racial status quo.     

Social factors influence solo and rat dyads exploration of an unfamiliar open field

Discrimination learning by macaca mulatta with option to switch between S+ and S−

Three rhesus monkeys were trained to press either of two response keys. A response on the reinforcement key during presentation of the reinforced stimulus produced a sucrose pellet followed by an intertrial interval, but during presentation of the unreinforced stimulus produced only the intertrial interval. A response on the switching key changed the discriminative stimulus from reinforced to unreinforced or from unreinforced to reinforced. The reinforced stimulus was presented automatically on half the trials, but could be produced only by a switching response on the other half. Switching tended to occur in three distinct stages during acquisition of discriminative behavior. The first stage was identified as "nondiscriminative switching"; the second as "nonswitching"; and the third as "discriminative switching".     

Experimental design symbolization and model derivation

A method of design symbolization (DS) is given for a class of designs in which all factors are related by complete crossing or by nesting. Characterization of acceptable DS's, and logical relational properties are given. It is shown how the design model can be obtained from the DS.The preparation of this article was supported by NIH Grant GM-11128, and by grants to the Institute of Human Learning by NSF and NIH.     

Near-death experiences and the measurement of blood gases

Although cerebral anoxia is not thought to be responsible for triggering near-death experiences (NDEs), the issue is not so clear in the case of hypercapnia. Detection of normal blood gases in Michael Sabom's (1982) case study seems to be the major reply to suggestions that hypercapnia may have a causal role in NDEs. We argue, however, that routine arterial measures of blood gases are not a reliable indicator of cerebral levels.
