The visible lights are emitted from illumination light emitting diodes (LEDs), which are expected to replace present lighting devices using conventional lamps, i.e. incandescent bulbs and fluorescent lamps, in the near future.
The conditioned stimuli (CSs) were pictures of lamps (i.e. blue, red, and yellow lights) that appeared within 1 of 2 rooms (i.e. an office or library) that served as the fear conditioning and extinction learning contexts.
The rooms were huge, graveyard-quiet, and with a few torchiere lamps I never missed the sun.
Flanked by two bright reading lamps, I was quietly absorbing a rather too sweet novel sent by a book club that I belong to when the telephone rang.
In my spacious bush tent reached by a wooden bridge, lit at night by paraffin lamps, I felt further from the rest of the world than ever.
Oh, the horror, the horror... Safely back at the lodge that night, eating red snapper at the ocean's edge, amid the tinkling bells and twinkling citronella lamps, I could laugh about it.
