The case for place: Text arrangement and reading skill

To what extent does the reader integrate visual information from one fixation to the next and derive a spatially extended representation of text? Experimental studies of transsaccadic fusion in reading produce conflicting evidence. The results from work on “stepped-text” presentation, in which words appear in a single physical location, have been used to argue that readers secure no advantage from the spatially extended page and that reading may proceed without the computation of spatial coordinates. It is suggested that this conclusion may be inaccurate. A processing decrement is found for materials above a critical level of complexity when presented in a “stepped” mode. This appears to derive from the reader’s need at times to reinspect parts of previously presented text. Reinspections of this kind, which appear to characterize the fluent reader, demand a degree of spatial coding. Two classical issues in the study of perception come together in the study of reading. First, what segments the continuous stimulus flux into discrete perceptible objects? The second is, what is the nature of the control system for eye movements? - Kolers (1983) This research is supported by a grant from the Economic and Social Research Council.     

Impact of Institutional Review Boards on cancer research

The concepts of informed consent and surveillance of human research designed to protect human subjects is commendable. The regulations of the Institutional Review Board (IRB) are having a major impact on clinical cancer research. There is greater administrative time needed of the investigator, the mechanisms of patient care have become cumbersome and some patients reject optional medical management that could be life saving. IRB regulations must be flexible to meet the needs of human subjects as well as those of the clinical investigator.     

Prismatic displacement and the remembered location of targets

Following adaptation, only the trained limb misreaches to the remembered location of targets. This suggests a change in the feit position of the trained limb, but conflicts with recent reports, and with the hypothesis that when a limb changes, the remembered location of targets encountered only by that limb undergo some change too. It suggests that information is stored independently of the mode of acquisition.     

Clinical application of conditioning and other behavioral techniques: Conceptual and professional considerations

It is only recently that conditioning and allied techniques have been applied on any large scale outside the laboratory. With the emergence of these procedures into the clinical world, in particular, a new class of problems present themselves. It is no longer sufficient to focus upon narrowly technical or theoretical problems; philosophies, social and practical issues must be taken into consideration and the new techniques evaluated conceptually and practically in direct comparison with their psychodynamic alternatives. Selected issues are presented and discussed.
