Endogenous Covert Spatial Orienting in Audition Cost-Benefit Analyses of Reaction Times and Event related Potentials

The presentstudy examines mechanisms ofendogenous covertspatialorienting inaudition as revealed by event-related brain potentials (ERPs) and reaction times (RTs). In one experimental condition, subjects were instructed to respond to any target tone irrespective of whether it was presented in a valid (spatially predictive cue), neutral (uninformative cue), or invalid (misleading cue) trial. In another experimental condition, only target tones presented at a cued position required a response-that is, subjects could completely ignore tones presented at the uncued ear. Cue validity had an effect on RT, which consisted in benefits for valid trials and in costs for invalid trials relative to the RTs in neutral trials. There were also distinct ERP effects of cue validity in the 100-300 msec time range. These ERP effects were enlarged in the condition in which uncued tones could be ignored. The effects of cue validity onRTsandERPsdemonstratedcovertorientinginauditionbothforstimulirequiring anovert response andalso for stimuli that did not require a behavioural response. It is argued that this attentional selection is located at intermediate stages of information processing, rather than at peripheral stages such as basic sensory-specific processing or response selection.     

Against Mother's Day and Employee Appreciation Day and Other Representations of Oppressive Expectations as Opportunities for Excellence and Beneficence

Appreciation and gratitude get good press: They are central virtues in many religious and secular ethical frameworks, core in positive psychology research, and they come highly recommended by the self‐improvement set. Generally, appreciation and gratitude feature as good things, in popular consciousness. Of course, on an Aristotelian model, the belief that these are virtues implies they are something people can get right or wrong. This paper examines bad appreciation and bad gratitude, characterizing forms of appreciation and gratitude at the center of some major social norms and practices, and demonstrating that they mask familiar oppressive expectations and power relations.
