Latency of the blink reflex and stimulus intensity J

The latency of the eyeblink reflex is inversely related to the intensity of the auditory or visual stimuli used to evoke it. This is true for both mechanical and muscle action potential methods for recording the response.     

The Non-Achievement Syndrome,Group Therapy,and Achievement Change

174 selected failing students at Illinois Institute of Technology were provided group counseling as a condition of their remaining in school. The assumption of the psychodynamics of the non-achievement syndrome was made regarding these students and a group counseling approach (NAS therapy) derived from an approach delineated by Roth and Meyersburg seemed appropriate and was utilized. 52 male subjects in this population were randomly selected for study as were 52 probationary, noncounseled males who were used as a comparison group. The results indicated that the counseled group increased their GPA's significantly and that these changes held over time. The GPA's of the comparison group did not increase significantly. The differences were attributable to the counseling experience.
