The autobiographies of 49 eminent psychologists were content analyzed in terms of autobiographically consequential experiences (ACEs). Most memories for ACE were not single episodes. Episodic ACEs did, however, share many characteristics of "flashbulb" and vivid memories elicited in studies using more traditional experimental procedures. Memories were concentrated during the college and early adult years. Thus, as in other autobiographical memory studies that have used older subjects, there was a pronounced reminiscence effect. These results were considered in light of Erikson's theory of adult personality development.
The present study investigates the relationship between the perception of bilateral symmetry and left-right disorientation in neurologically-intact adults. Using tachistoscopic presentation of stimuli and a choice reaction-time procedure, we found a small but consistent trend toward quicker symmetry judgements in left-right confused subjects. Possible neuropsychological mechanisms underlying this curious finding are discussed.
The rate at which an intermittent visual target appears to be flashing is a function not only of its actual pulse rate, but of its intensity as well. This was shown by having 6 Os match the flash rates of 2 contralaterally presented targets having various intensity relations. The standard target was set to pulse at 4, 8, 12, 16, 24, or 32 cps at intensity levels of 630, 63, 6.3, or .63 apparent ftc. The O adjusted the pulse rate of the variable, 630 apparent ftc., so that it appeared to be flashing at the same rate as the standard. Flash rate and intensity were found to be independent at the lowest pulse rates used. At the higher values of pulse rate, a 30-db. reduction in intensity produced as much as a 100% increment in flash rate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
