Subjects tried to recall the location of a tactile stimulus on the underside of the forearm after delays of 0, 3, 5, 10, 15, 30, 45 and 60 sec. When “rehearsal” was prevented by requiring subjects to count backwards during the delay, accuracy of recall decreased systematically reaching an asymptote after 45 sec. When subjects were left free to “rehearse,” this did not affect the decline in accuracy over the first 10 sec. Between 10 and 15 sec. there was a significant increase in accuracy followed by a slow decline which had not reached asymptote by 60 sec. It is suggested that tactile STM (short-term memory) depends on two processes, a fading sensory trace which is unaffected by distraction and a less labile system which does not appear to be verbal but which depends on “rehearsal.” 相似文献

Threshold elevations (TE) were determined at a testsite on the left thigh with the simultaneous presentation of combinations of maskers positioned on the trunk. It was found that the resultant TE from groups of up to 10 multiple maskers is nearly equal to the addition of the TE produced by each masker separately. 相似文献

The purpose of the present research was to examine the influence of cognitive processes on discourse global coherence ability measured across different discourse tasks and collected from younger (n = 40; 20–39 years) and older (n = 40; 70–87 years) cognitively healthy adults. Study participants produced oral language samples in response to five commonly used discourse elicitation tasks and they were analyzed for maintenance of global coherence. Participants also completed memory and attention measures. Group differences on the global coherence scale were found for only one type of discourse—recounts. Across discourse elicitation tasks the lowest global coherence scores were found for recounts compared to the other discourse elicitation tasks. The influence of cognitive processes on maintenance of global coherence differed for the two age groups. For the younger group, there were no observed significant relationships. For the older group, cognitive measures were related to global coherence of stories and procedures. 相似文献

The U.S. Reserve Officer Training Program (ROTC) conducts systematic assessments of cadets’ leadership abilities during field training exercises (FTX) to assess their leadership abilities. While cadets in ROTC programs learn specific tactical operation procedures to augment FTX performances, much less is known about the relationship between psychological variables and squad leadership performance. To this end, 220 cadets completed self-efficacy, psychological flexibility, and grit questionnaires, which were then compared to FTX performance scores. Results underscored that only self-efficacy was significantly related to cadets’ squad leadership ability. Furthermore, prior service in the U.S. Army had no effect on the performance score one attained, highlighting an interesting paradox. Therefore, while self-efficacy can be cultivated through prior experiences, it seems more prudent to educate ROTC cadets on how to apply psychological skills to bolster self-efficacy in preparation for upcoming challenging leadership experiences. 相似文献

We argue that the practice of engineering does not exist outside the domain of societal interests. That is, the practice of
engineering has an inherent (and unavoidable) impact on society. Engineering is based upon that relationship with society
(inter alia).
An engineer’s conduct (as captured in professional codes of conduct) toward other engineers, toward employers, toward clients,
and toward the public is an essential part of the life of a professional engineer, yet the education process and professional
societies pay inadequate attention to the area. If one adopts Skooglund’s definition of professional ethicsI (how we agree to relate to one another), then the codes of professional conduct lay out a road map for professional relationships.
As professionals, engineers need to internalize their codes and to realize that they have a personal stake in the application
of codes as well as the process of developing the codes. Yet, most engineers view professional codes as static statements
developed by “others” with little (or no) input from the individual engineer. Complicating the problem, questions of professionalism
(such as ethics) are frequently viewed as topics outside the normal realm of engineering analysis and design. In reality,
professional responsibility is an integral part of the engineering process. 相似文献
