Post-Knowledge of Results Delay: Effects of Interpolated Activity on Learning and Performance

Abstract

The present experiment investigated the effects of interpolated processing activity (IPA) during the post knowledge of results (KR) interval. The study attempted to correct some of the problems inherent in previous research by using a ballistic timing criterion task and assessing the effects of interpolated processing activity (IPA) on both acquisition and No KR transfer trials. To insure that the efficacy of the IPA manipulation, a paced task was used and performance was assessed. Two levels of post-KR delay (5 and 10 s) were factorially combined with two levels of IPA (IPA or No IPA) to yield four experimental groups. Each subject completed 30 KR acquisition trials and 20 No KR transfer trials. Interresponse interval was held constant. In contrast to many previous studies, IPA interfered with the subjects' ability to learn and perform the criterion movement time of 150 ms. Both the memory trace and the perceptual trace were similarly affected. The detrimental effects of IPA on absolute error and objective-subjective error differences found during acquisition persisted during KR withdrawal.     

Towards a collaborative methodology: An ethnography of widening educational participation

This paper examines my attempts to develop a collaborative methodology, and critically considers the limitations and possibilities of this approach. It draws on a small-scale ethnography of widening educational participation undertaken for my doctoral degree. I worked with a group of access students in a UK further education college to develop the methods and methodology, to identify research questions and key areas of focus and, to a lesser extent, to analyse the data. Post/structural analytical tools enabled co-participants to deconstruct hegemonic neo-liberal discourses of widening participation. Feminist theory enabled the refashioning of radical discourses that are concerned with destabilising unequal relations of power in research and in education. In the paper I consider issues of power, research relationships, author-ity, reflexivity and ethics in collaborative methodology.     

Vocabulary,Context, and Speech Perception Among Good and Poor Readers

This study examined the interaction between speech perception and sentential context among 13 poor readers and 49 good readers in grades one to three. Children's performance was examined on tasks assessing expressive and receptive vocabulary, reading skill, phonological awareness, pseudoword repetition, and phoneme identification. Good readers showed clearly defined categorical perception in the phoneme identification task for both sentence frames biased to the identification of the /b/ or /p/ phoneme. The /b/–/p/ category boundary for the BATH frame was at longer voice onset times (VOTs) than the boundary for PATH frame. Poor readers showed less sharply defined categorical perception with both sentence frames. Although poor readers did not show a shift in the /b/–/p/ category boundary, sentential context did affect the overall rate with which phonemes were identified as /b/ or /p/ at each VOT. These findings suggest that semantic information may operate as a compensatory mechanism for resolving ambiguities in speech perception. Furthermore, expressive vocabulary was more closely related than receptive vocabulary to individual differences in reading and phonological processing, providing support for the phonological distinctness hypothesis.     

#2: Freedom of Movement throughout Labor

In this position paper-one of six care practice papers published by Lamaze International and reprinted here with permission-the benefit of allowing freedom of movement throughout labor is discussed and presented as an evidence-based practice that helps promote, protect, and support normal birth. The paper is written for childbearing women and their families. The accompanying commentary-written by a well-known author of numerous articles and books on childbirth-compares the activities of women in two birthing environments: the conventional medicalized setting and the unconventional naturalistic setting. Reasons why women may not move in labor are presented. Lamaze International encourages women to use movement in labor in order to make labor more comfortable and more efficient.
