This paper identifies the conclusion of a romantic relationship as a significant loss for adolescents. The grief response initiated by this loss is frequently disenfranchised by adults and peers. Adolescent grief symptomatology as well as strategies for surviving a loss are outlined.  相似文献

B acklund , F. A., and B ergström , S.-S. Subjective scaling based on threshold measurements. Scand. J. Psychol ., 1961, 2, 88–92. A method of establishing subjective scales by means of absolute threshold measurements is reported. The method is successfully applied to data from the perception of motion and time.  相似文献

A small, light eye-movement recorder, capable of registering eye movements from the smallest voluntary movements to movements of 20 degrees of arc, is described. A miniature light projector gives a beam of infrared (or blue) light, which is reflected by the cornea of the eye. The beam is deflected by any movement of the eye. An optical system transforms the motion of the beam into changes of light intensity. These are translated into magnified fluctuations of current in a multiplier phototube. The output is translated into graphic form by an ink-writer fitted with a D.C. amplifier. The apparatus, except for the writer but including a helmet, weighs about 300–500 g and is mounted on the subject's head without appreciably disturbing the field of vision.  相似文献

After-effects in haptic perception have been little studied. But they seem to be prominent, and easy to elicit. An after-effect of the perception of the vergence of two surfaces is described, and is shown to be independent of the slant of the surfaces. It is not “figural.” Spatial perception with the hands, as well as with the eyes, is apparently based on a fluid and adaptable receptive system.  相似文献
