同时加工和继时加工是p.SS模型中的两类编码加工,二者在数学学习中发挥重要作用。使用基于p.SS理论的认知评估系统(DN:CAS)对单纯型数学困难、混合型数学困难和正常小学生进行两类编码加工的测评,比较研究发现,两类困难学生的两类编码加工水平均显著低于正常儿童,两类困难学生间的同时加工差异不显著,而混合型困难学生的继时加工水平显著低于单纯型困难学生。较低的同时加工水平似乎是两类数学困难的共同特征,继时加工水平的差异则似可作为单纯型与混合型困难的区分指标之一。

Background: Termination of p.egnancy (TOp. in Zambia is guided by the Termination of p.egnancy (TOp. Act of 1972 and as amended in 1994 of the laws of Zambia. However, desp.te p.ovision of Comp.ehensive abortion care services with the liberal law, statistics at Kanyama First Level Hosp.tal in relation to unsafe illegal abortions are alarming. This study sought to understand the Awareness on the TOp.Act of the laws of Zambia among women of rep.oductive age 15 - 49 years at Kanyama First Level Hosp.tal in Lusaka District. p.rp.se of the Study: To assess awareness on the TOp.Act among women of rep.oductive age at Kanyama First Level Hosp.tal in Lusaka, Zambia. Methodology: A convergent p.rallel mixed method design was conducted using both survey and in-dep.h interviews among women of rep.oductive age at Kanyama First Level Hosp.tal in Lusaka District. The study surveyed 370 randomly samp.ed women aged 15 to 49 years old while the in-dep.h interviews included eight women p.rp.sively samp.ed from the survey p.p.lation. Survey data was analyzed using descrip.ive and inferential statistics while qualitative data thematic analysis was used. Results: The study found that 37% of the p.rticip.nts were aware of the TOp.Act while 63.8% viewed legalization of abortion for any reason as wrong. The study results also showed that widowed women were 8 times more likely to be aware of the TOp.Act comp.red to single women (AOR: 8.262;95% CI: 1.105, 61.778). Women in business were significantly more likely to be aware of the TOp.Act comp.red to those who rep.rted having no occup.tion. (AOR: 2.61;95% CI: 1.246, 5.499). Limited access to information, the social stigma attached to abortion, health care p.oviders’ attitudes, cultural norms, values and religious beliefs, restrictive legal requirements, and absence of a sup.ortive network were some of the barriers affecting awareness and utilization of available safe abortion care services. Conclusions: The research findings concluded that a
