PURPOSEThere are many visually impaired people who can drive legally with bioptic telescope. Drawing on the experience of drivers with reduced vision, this study investigated the role of motion perception and visual acuity in driving, under simulated low visual acuity.METHODSTwenty normally sighted participants took part in a driving hazard perception (HP) test, in four different conditions: with/without motion interruption and with/without simulated low visual acuity. In interrupted motion conditions a mask frame was inserted between every frame of the driving videos. In simulated low visual acuity conditions, participants wore glasses with diffusing filters that lowered their visual acuity to 20/120 on average. Participants’ response time, hazard detection rates, and HP scores, which combined response time and detection rate, were compared.RESULTSRepeated measure ANOVA revealed that the HP scores significantly declined from 20.46 to 16.82 due to the motion mask (F(1,19)= 9.343, p = 0.006). However, simulated low visual acuity did not affect HP scores (F(1,19) = 1.807, p = 0.195). The interaction between vision and mask was not significant (F(1,19) = 1. 295, p = 0.269). The decline in score was mostly due to significant decrease in detection rate, from 0.80 to 0.64, due to the motion mask (F(1,19) = 16.686, p = 0.001).CONCLUSIONSIn this experimental setting, human observers relied largely on motion information for detecting driving hazards, rather than high visual acuity. This finding might help explain how visually impaired drivers can compensate for their impaired vision during driving.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

Sense Of Obligation

Abstract Tomasello offers a compelling account of the emergence of humans’ sense of obligation. We suggest that more needs to be said about the role of affect in the creation of obligations. We also argue that positive emotions such as gratitude evolved to encourage individuals to fulfill cooperative obligations without the negative quality that Tomasello proposes is inherent in obligations.
