Spacing effects and their implications for theory and practice

There is considerable evidence, gathered in a variety of settings and across many different types of materials and procedures, that spaced repetitions—regardless of whether they are in the form of additional study opportunities or successful tests—are a highly effective means of promoting learning. Research on spacing effects is reviewed and its theoretical and educational implications are examined. It is concluded that spacing effects can best be understood in terms of the accessibility hypothesis, and that spaced repetitions have considerable potential for improving classroom learning.     

Transition for Deaf and Hard-of-Hearing Students: A Blueprint for Change

The large and growing number of deaf and hard-of-hearing adults who are "low-functioning deaf" (LFD), the unmet needs of many young people who are deaf or hard of hearing, and the continuing high rates of dropping out argue for a change in secondary programming for multiply disabled deaf and hard-of-hearing students and for others who are at risk of becoming LFD as adults. The LFD designation refers to youth and adults who read at very low levels, whether or not they have a second disability in addition to hearing impairment. This article reviews research related to transition for adolescents with disabilities as well as those who are deaf or hard of hearing. It then offers a case for change, one that, for the United States, represents a poignant return to a time past.     

Classroom Management for Project Work: an application of correspondence training

This study is a further attempt to apply correspondence training in the classroom in order to improve learning outcomes. Using this strategy a class of middle school pupils was encouraged to show more initiative, independence and self‐regulation in planning and carrying out topic work. The pupils were required to forecast what they proposed to achieve in a certain period and then to check up at the end to see how far they had been successful. In addition, upon hearing an audible signal, they were required to decide whether they were ‘on‐task’ and whether they were working well. The outcome was that the pupils achieved a better work output in terms of both quantity and quality than before. In addition, they gained valuable experience in forward planning and in working independently.     

Incubator firm failure or graduation?: The role of university linkages

One of the theoretically important factors for incubator firm performance is the strength of their linkages to the research university sponsoring the technology incubator. Herein, we focus on two types of university linkages to the sponsoring institution: a license obtained from the university and a link to university faculty, while controlling for incubator firm linkages to non-sponsoring research universities, among other factors. We propose that a university link to the sponsoring institution reduces the probability of new venture failure and, at the same time, retards timely graduation. Further, we suggest that these effects are more pronounced the stronger the university link. Due to the difficulty of obtaining fine-grained longitudinal data, the incubation literature is characterized by a dearth of studies focusing on incubator firm differential performance. We attempt to take a first step towards closing this gap by testing these hypotheses through following 79 start-up firms incubated in the Advanced Technology Development Center at the Georgia Institute of Technology over the 6-year period between 1998 and 2003. We find broad support for the hypotheses advanced.     

Interference and Inhibition in Cognition and Behavior: Comments on the Commentaries

In our target article (Dempster & Corkill, 1999a) we presented an overview of recent work on interference and inhibition in cognition and behavior. The commentators provided highly informative feedback about a range of implications of this new body of work for educational psychology, including learning disabilities. In our response to the commentators, we reply to two relatively broad topics they touch on: consciousness and the functionalist tradition of American psychology. We also remark on two relatively narrow issues raised by the commentators: what constitutes irrelevant information and perseveration in the missing addend task.     

Longitudinal course of rapid naming in disabled and nondisabled readers

The Rapid Automatized Naming Test (Denckla and Rudel 1974) was studied cross-sectionally in an sample of kindergartners (n=342) at-risk for reading disability (Study 1), and longitudinally in an n=160 epidemiological normal sample of children tested in first, third, fifth, and eighth grades (Study 2). Study 1 showed faster absolute naming speeds for those with near perfect untimed alphabet recitation, but the stronger and more orderly relation (at r=.31, p<.0001) was between three levels of alphabet recitation accuracy and the relative number/letter naming speed advantage (ratio of mean number/letter naming speed minus mean color/object naming speed over mean color/object naming speed). In Study 2, the number/letter advantage was already strongly present by first grade, and did not increase significantly thereafter, but absolute naming times improved steadily across grades in an exponential decay function. In this sample, the relative number/letter advantage was not related to reading level. However, the absolute color/object naming speed was strongly related to reading level and vocabulary across grades. Norms for the Rapid Automatized Naming Test based on the epidemiological normal sample tested in Grades 1, 3, 5, and 8 are presented in the appendix.
