Verbal and spatial short-term memory: common sources of developmental change?

Verbal and spatial span, articulation and tapping rate, and verbal and spatial speed-of-search tasks were administered to sixty 6- to 12-year-olds. A variance-partitioning procedure was then used to identify age-related and age-invariant components of variance in span. Outcomes were very similar for verbal and spatial span, in particular, (i) most of the age-related variance was shared by the speed-of-search and rate predictors, (ii) articulation rate provided an age-independent contribution, (iii) changing-state versions of predictor tasks did not account for variance over steady-state versions, and (iv) predictors of the same modality as the span task did not outperform predictors of the other modality. We conclude that verbal and spatial short-term memory appear to rely on similar processes when serial recall is required and that developments in span are closely tied to increases in processing speed.     

Studies on Interfaith Relations: Latest Input for Authority Management Review (AMR) in Malaysia

Malaysia is a multi-religious society with 28.3 million people. The country had succeeded in managing religious diversity for almost fifty-seven years. This includes the promotion of interfaith relationships granted under the right to religious freedom, which is protected by the State. There are, however, emerging interfaith challenges, including conversion from one faith to another and reversion back to the original faith, these types of challenges appearing especially in the early millennium. This article reviews the ten latest research studies on interfaith issues in Malaysia and identifies useful themes for authority in exercising management review. Using the content analysis method, this study found that there are several important managerial aspects to be taken into serious consideration, including setting clear parameters for freedom of religion in Malaysia, clear procedures for managing religious conflict, managing faith with respect, and effectively promoting media advocacy. The findings also give insights on the development of interfaith studies in Malaysia.     

从智力的三元理论到成功智力:是对IQ的再次超越吗?

本文以智力的约定性为立论,把超越界定为智力的约定性的广度、深度和效度的大幅度提高。将斯腾伯格对智力的研究放到智力理论研究的历史过程中,对斯腾伯格的三元智力理论及成功智力理论对IQ的超越做了分析。指出传统IQ是学业差异约定,三元智力是多元权变约定,成功智力是人生成功约定,后者都是对前者的超越,成功智力是对IQ的再次超越。最后尝试性地提出智力约定性的“树”的隐喻。本文对智力理论的研究和教育实践有参考价值。     

Verbal and Spatial Short-term Memory: Two Sources of Developmental Evidence Consistent with Common Underlying Processes

Developments in serial short-term memory (STM) typically have been assessed using verbal items, and mechanisms of development unique to the verbal system have been postulated. Here we review two studies of the development of spatial STM. The first (Chuah & Maybery, 1999) showed that variance in spatial span was partitioned among a set of predictor variables in a configuration very similar to that found for verbal span. The second (Maybery & Chuah, 1999) examined the timing of recall for spatial sequences. Intervals between touches as children recalled spatial sequences showed comparable effects to those reported for the oral recall of verbal sequences. Discussion focuses on processes that could serve both verbal and spatial memory and mediate span development.     

The long-term effects of mild head injury on short-term memory for visual form, spatial location, and their conjunction in well-functioning university students

Research has suggested the presence of subtle long-term cognitive changes in otherwise well-functioning individuals who have previously sustained a mild head injury (MHI). This paper investigated the long-term effects of MHI on visual, spatial, and visual-spatial short-term memory in well-functioning university students. Sixteen students who reported having sustained a MHI were compared to 16 controls on tests of short-term memory (STM) for abstract polygons in haphazardly arranged locations. The three tests differed only in the requirements for recall (shapes for the visual task, locations for the spatial task, and the shapes in their respective locations for the visual-spatial task). MHI participants were selectively impaired on spatial memory, suggesting that tasks of spatial STM may be more sensitive, compared to tasks of visual STM, to the subtle long-term cognitive changes that may be present after a MHI.
