采用Go/No-go联想任务测验(Go/No-go Association Task,GNAT)对268名大学生进行内隐自杀意念的测量,探讨其用于自杀意念测量的特点和效果.研究发现:GNAT内隐测量有良好的信效度;大学生内隐自杀意念发生率为38.8%(104/268);GNAT测量中存...采用Go/No-go联想任务测验(Go/No-go Association Task,GNAT)对268名大学生进行内隐自杀意念的测量,探讨其用于自杀意念测量的特点和效果.研究发现:GNAT内隐测量有良好的信效度;大学生内隐自杀意念发生率为38.8%(104/268);GNAT测量中存在顺序效应;被试将"自我词+积极词"与"自我词+消极词"联结的时间差异不显著,而敏感性差异显著;被试将"他人词+积极词"与"他人词+消极词"联结的时间差异和敏感性差异均显著;内隐自我反应时指标、内隐自我敏感性指标以及内隐他人敏感性指标在性别、民族、是否担任学生干部、是否独生子、生源地以及家庭结构上的差异不显著;内隐他人反应时指标在这些人口学变量中差异显著.因此,GNAT可用于大学生内隐自杀意念的测量.展开更多

Rove beetles used in this study came from a laboratory-reared colony. A rating scale from 1 to 5, based on percent missing （1 = 0 to 10%, 2 = 11 to 30%, 3 = 31 to 50%, 4 = 51 to 75%, and 5 = 76 to 100%）, was used to objectively assess the amount of oatmeal and number of fungus gnat larvae consumed by each rove beetle adult and larva. In all the choice tests, A. coriaria adults and larvae preferred to feed on fungus gnat larvae （78% and 69%, respectively） significantly more so than oatmeal （9% and 5%, respectively） based on the amount of oatmeal and number of fungus gnat larvae consumed after 4 and 6 hours. There were relatively minimal differences in the amount of food consumed for both adults and larvae after 4 and 6 hours. The results of this study indicate that oatmeal may be an inexpensive supplemental food source, during the rearing process, which will not inhibit the effectiveness of rove beetles to control fungus gnat larvae when released into greenhouses.展开更多
