Memory codes for temporal and nontemporal samples in many-to-one matching by pigeons

Pigeons were trained to match temporal (2 and 8 sec of keylight) and color (red and green) samples to vertical and horizontal comparison stimuli. In Experiment 1, samples that were associated with the same correct comparison stimulus displayed similar retention functions; and there was no significant choose-short effect following temporal samples. This finding was replicated in Phase 1 of Experiment 2 for birds maintained on the many-to-one mapping, and it was also obtained in birds that had been switched to a one-to-one mapping by changing the comparison stimuli following color samples. However, in Phase 2 of Experiment 2, when the one-to-one mapping was produced by changing the comparison stimuli following temporal samples, a significant choose-short effect was observed. In Experiment 3, intratrial interference tests gave evidence of temporal summation effects when either temporal presamples or color presamples preceded temporal targets. This occurred even though these interference tests followed delay tests that failed to reveal significant choose-short effects. The absence of significant choose-short effects in Experiment 1 and in Phase 1 of Experiment 2 indicates that temporal samples are not retrospectively and analogically coded when temporal and nontemporal samples are mapped onto the same set of comparisons The interference test results suggest that the temporal summation effect arises from nonmemorial properties of the timing system and is independent of the memory code being used     

Becoming literate in Chinese: a comparison of native‐speaking and non‐native‐speaking children

How do native Chinese‐speaking (CS) and non‐Chinese‐speaking (NCS) children learn to read and write in Chinese? In the present study, 29 CS and 34 NCS second and third graders aged 76 to 122 months (M = 93.65) participated in an experiment where they were taught 16 new Chinese characters in one of four conditions – copy, radical, phonological and look–say. Results showed that the copying condition best facilitated writing of Chinese characters for both groups, whereas radical knowledge facilitated only CS children's writing. NCS children benefited more from the phonological condition than from the look–say condition in learning to read Chinese. These results highlight the effectiveness of copying practice for all children learning to write Chinese. However, approaches to reading and writing Chinese may differ somewhat depending on the Chinese background knowledge of the children as well. Teaching children Chinese should be geared towards the strengths of different groups for learning.

Academic self-efficacy,sense of coherence,hope and tiredness among college students with learning disabilities

Abstract

Some resilient students with LD succeed ‘against the odds’ and reach college. The goals of the study are to explore their resources and barriers during their studies. The relationships between academic self-efficacy (ASE) and personal resources (sense of coherence (SOC) and hope) among college students with learning disabilities (LD) will be examined. The sample consisted of 438 college students divided into two subgroups: 149 students with LD and 289 Non-LD students. Results indicated that college students with LD reported lower levels of ASE, as well as lower levels of hope subscales and SOC. Persistent challenges of early learning distress experienced by those students during school periods continue to be prevalent during their college years. The ASE was predicted by the personal resources, and the risk factor (tiredness lost its significance). The importance of personal resources (SOC and hope subscales) was further emphasised by the mediation model (PROCESS). They mediated the relationships between LD and ASE. These outcomes call for empowering interventional programmes in order to promote hopeful thinking and personal coherence.     

The Impact of Student Learning Outcomes Assessment on Technical and Professional Communication Programs

Because of accreditation, budget, and accountability pressures at the institutional and program levels, technical and professional communication faculty are more than ever involved in assessment-based activities. Using assessment to identify a program's strengths and weaknesses allows faculty to work toward continuous improvement based on their articulation of learning and behavioral goals and outcomes for their graduates. This article describes the processes of program assessment based on pedagogical goals, pointing out options and opportunities that will lead to a meaningful and manageable experience for technical communication faculty, and concludes with a view of how the larger academic body of technical communication programs can benefit from such work. As ATTW members take a careful look at the state of the profession from the academic perspective, we can use assessment to further direct our programs to meet professional expectations and, far more importantly, to help us meet the needs of the well-educated technical communicator.     

A study of race and gender bias in the punishment of handicapped school children

There is scant research concerned about punishment of handicapped, minority students in public schools. The purpose of this study was to investigate race and gender, types of rules violations, types of punishments, referral rates, referral frequencies, and follow-up activities to determine differences in treatment by race, sex, and handicapping condition. The sample consisted of 4,391 discipline files representing records from 9 schools in a district (K-12). All data were analyzed using the Chi Square statistic. It was demonstrated that racial bias existed in the administration of punishment, and that Black, male handicapped students were punished more severely than others for commission of the same offenses.     

Is accreditation ‘on the right track’? The views of Portuguese academics

In many countries, quality assurance systems rely on study programme accreditation. As with all quality assurance mechanisms, accreditation should also be continuously improved in order to maintain its relevance as a promoter of study programme quality. A way to move accreditation forward is by taking into account academics’ views, interests and needs about the process, since their support for it is paramount for its success and effectiveness. This paper analyses Portuguese academics’ knowledge and views on accreditation with the aim of understanding if the process is being supported and is on the right route for being effective. It is based on the analysis of 1484 academics’ answers to a questionnaire distributed in 16 higher education institutions. This analysis reveals a moderately positive attitude of academics towards accreditation, reflected in an only moderate knowledge of the process as well as in a mild agreement with its characteristics and implementation features. This suggests that there is room for improvement to bring this quality assurance mechanism closer to academics’ expectations and needs and therefore to improve accreditation’s effectiveness.

     

Morphological,phonological, and orthographic differences between the spelling of normally achieving children and basic literacy adults

In this study, we compared 41 adults in a basic literacy class with 92 achievement-level-matched children on their use of English print conventions, as inferred by a qualitative analysis of spelling errors. The two groups followed similar patterns in their mastery of basic spelling features, including letter reversals, consonant blends, and short vowels, with the adults showing relatively more advanced skill in using orthographic patterns. However, the adults made a preponderance of misspellings that were rarely made by the children, including omissions, substitutions, and additions of derivational and inflectional morphemes, and neglect of word endings in general. The findings indicate clear morphological difficulties along with more subtle phonological coding deficits. We suggest that low literacy adults would benefit from specific direct instruction in linguistic analysis, with particular attention to the morphological principles underlying inflections and derivations. Such instruction should be based on a careful assessment of reading and spelling knowledge.
