Abstract

Prospective memory is the memory of the 1990s, the rise of a new field of study, it refers to future events or acts of memory, and retrospective memory corresponding to a long-term memory types. From the definitions, characteristics, research methods, processing mechanism, influencing factors of prospective memory studies have been reviewed. Delay interval is an important feature of prospective memory, proven delayed prospective memory mechanism is of great significance, many researchers insight into the nature of prospective memory, respectively, from a different angle by delay execution paradigm (Einstein, McDaniel, 2003) and the classic experimental paradigm (Einstein, McDaniel, 1990), the delayed impact on prospective memory a lot of research has made gratifying achievements, but in view of the experimental material, different experimental results of the task divergence, but Many studies have concluded that forward-looking The memory of the first few minutes of a very complex coding stored procedures. Therefore, this variable has a need for further study. Up to now, the study of prospective memory mostly classic experimental paradigm and delay the implementation of the paradigm of experimental results with realistic difference, contrary to the purpose of prospective memory. Real life, most of the individual prospective memory failure is due to interrupt the sudden occurrence of this article that interrupted the emergence bound to produce a prospective memory task - the task of recovery was interrupted. The interrupt feature few studies done abroad infancy, is in the data collection phase. Taking these two aspects, the paper by two experiments foresight in mind the performance under different interrupt latency study Henan University, Department of Psychology undergraduates as subjects, to resume the interrupted task as a prospective memory task to restore The number of interrupt tasks as prospective memory performance. Experiment 1 single factor completely randomized design, set around the beginning of the interrupted task four different experimental conditions: baseline conditions: no delay silent; Coding Tip: prompt delay interval; coding delay: delay silent; retrieve delay delay before the start of the new task: interrupt task completed. Experiment 2 uses the same subjects design, set two different experimental conditions: baseline conditions: the same experimental baseline conditions; Search Tips conditions: prompt appear along with delay. Through experiments found that the different interrupt latency on Prospective Memory significant difference, mainly to the following conclusions: 1, in the context of interrupted suddenly appear or does not help, even if the delay time is very short (less than 3 minutes) , the individual is also very easy to forget to resume interrupted task. 2, interrupt appears to interrupt a short delay before the task begins or explicitly prompted conducive to interrupt the task of recovery, but the prompt itself does not improve the individual prospective memory scores. 3, increase the interrupt task to the end of the delay interval prior to the start of the new task, free from competition for cognitive resources between different tasks, more conducive to individual recovery was interrupted task. Interrupt the end of the mission before the start of the new task accurate description of the target cues can greatly improve the achievement of individual recovery was interrupted task. 5, effective retrieval cues than to provide effective coding clues more conducive to the recovery of interrupted tasks.
