Three experiments explored a speed‐accuracy tradeoff reflecting decreasing response times (RTs) and increasing errors across trials in a data entry task. In Experiment 1, cognitive and motoric stressors were independently added to data entry, with the combination of stressors yielding the greatest decline in accuracy across blocks. Experiment 2 compared mental multiplication and simple data entry and manipulated the provision of feedback. Accuracy improved with both mental multiplication and feedback. Experiment 3 varied only the concluding keystroke; this extra requirement led to overall improvements in accuracy. In each experiment, RTs improved across trials. These results suggest that cognitive complications can serve as antidotes to inhibitory effects and can overcome the decline in accuracy due to continuous work on data entry.

Two experiments examined the effects of memory set size and information structure on learning and retention. Participants
learned 48 (small set) or 144 (large set) facts about individuals, and were tested over 48 facts. The test facts included
either 4 facts about 12 individuals (12-person condition) or 12 facts about 4 individuals (4-person condition). During learning,
there was an advantage for the small-set group in the 4-person condition, but a disadvantage in the 12-person condition. During
testing, there was an advantage for the 4-person condition relative to the 12-person condition for the small-set group, even
when the conditions were equated in terms of name exposure. The results support a mental model account of memory representation
and retrieval. 相似文献

Collective Apologies and Their Effects on Forgiveness: Pessimistic Evidence but Constructive Implications 下载免费PDF全文
In the last three decades, there has been an explosion in the frequency with which leaders of groups have issued official apologies for collective transgressions. These apologies are commonly assumed to lay a pathway to forgiveness and reconciliation, but empirical examination of the downstream consequences of collective apologies is still in its infancy. In this article, we review a series of studies—including interview studies, survey studies, and experiments—that question the assumed wisdom that collective apologies lead to intergroup forgiveness. Reasons for the muted evidence of an apology–forgiveness link at the intergroup level are elaborated, and implications for how best to issue gestures of reconciliation and remorse are discussed. 相似文献

Any technique that conserves classroom instructional time without sacrificing the amount learned is of great educational value. This research compared a laboratory analogue of the clicker technique to analogues of other classroom pedagogical methods that all involve repeated testing during teaching. The clicker analogue mimics the classroom practice of dropping material that is understood by the majority of the class, as revealed by testing with clicker questions, from further lecture. A fact learning and retrieval paradigm was used, in which college students learned facts about unfamiliar countries. Compressing instruction time based on group-level performance produced as much learning as no compression and as compression based on individual-level performance. Results suggest that the clicker technique is an efficient and cost-effective method of conserving instructional time without loss of amount learned. 相似文献

A case study of community-based participatory research ethics: The healthy public housing initiative
We conducted and analyzed qualitative interviews with 12 persons working on the Healthy Public Housing Initiative in Boston,
Massachusetts in 2001. Our goal was to generate ideas and themes related to the ethics of the community-based participatory
research in which they were engaged. Specifically, we wanted to see if we found themes that differed from conventional research
that is based on an individualistic ethics. There were clearly distinct ethical issues raised with respect to projects and
individuals who engage in community-based collaborations. The differences that arose from the interviews were seeking equality
between the partners, the need for the community partner to defend the community, dealing with unflattering data, meeting
community expectations and producing tangible benefits to the community.

Two experiments investigated effects of articulatory processing on number data entry. Participants entered four-digit numbers presented as either words or numerals on a keyboard, either under an articulatory condition or in silence. In Experiment 1, the articulatory condition was articulatory suppression; in Experiment 2, it was vocalisation. In Experiment 1, the articulatory suppression group typed initial digits faster than the silent group, but for subsequent digits, the opposite pattern occurred at least with word stimuli. In Experiment 2, the silent group typed initial digits faster but typed subsequent digits somewhat slower than the vocalisation group. Thus, articulation of numbers, which promotes entry into the phonological loop of working memory, retards processing of initial digits but enhances processing of subsequent digits. 相似文献

We established a general genetic counseling clinic (GCC) to help reduce long wait times for new patient appointments and to enhance services for a subset of patients. Genetic counselors, who are licensed in Tennessee, were the primary providers and MD geneticists served as medical advisors. This article describes the clinic referral sources, reasons for referral and patient dispositions following their GCC visit(s). We obtained patients by triaging referrals made to our medical genetics division. Over 24 months, our GCC provided timely visits for 321 patients, allowing the MD geneticists to focus on patients needing a clinical exam and/or complex medical management. Following their GCC visit(s), over 80 % of patients did not need additional appointments with an MD geneticist. The GCC allowed the genetic counselor to spend more time with patients than is possible in our traditional medical genetics clinic. Patient satisfaction surveys (n?=?30) were very positive overall concerning the care provided. Added benefits for the genetic counselors were increased professional responsibility, autonomy and visibility as health care providers. We conclude that genetic counselors are accepted as health care providers by patients and referring providers for a subset of clinical genetics cases. A GCC can expand genetic services, complement more traditional genetic clinic models and utilize the strengths of the genetic counselor health care provider. 相似文献
