Comments on the article by J. L. Alpert et al (see record 2000-13581-002), which presented the report of the American Psychological Association Working Group on Investigation of Memories of Childhood Abuse. The authors discuss 4 issues in this commentary: (a) the assumptions and evidence used to support the case for dissociated and recovered memories (noting that the evidence is weak and the assumptions internally inconsistent as well as contradictory to a mass of experimental evidence about human memory); (b) the process by which dissociated memories are said to be recovered (events that were originally very poorly encoded as fragmentary, kinesthetic memories cannot be recovered with accuracy later); (c) 4 bodies of relevant, but neglected, research on human memory (reminiscence and hypermnesia, effectiveness of retrieval cues, priming in implicit memory tests, and intentional forgetting); and (d) the issue of appropriate research strategies to gain evidence on the thorny issues of long-delayed retrieval of information. Current evidence does not support the conclusion that memories of repeated abuse are dissociated and recovered with accuracy years later.

In 3 experiments, the authors examined part-set cuing effects in younger and older adults. Participants heard lists of category exemplars and later recalled them. Recall was uncued or cued with a subset of studied items. In Experiment 1, participants were cued with some of the category names, and they remembered fewer never-cued categories than a free-recall condition. In Experiment 2, a similar effect was observed for category exemplar cues. There was also an age difference: By some measures, a small number of cues impaired older adults more than younger. Experiment 3 replicated this result and found that older adults were disproportionately slow in the presence of cues. Across experiments, older adults showed robust part-set cuing effects, and sometimes, they were disproportionately impaired by cues. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

By combining heat and power generation, mini‐combined and micro‐combined heat and power systems (MCHP) provide an efficient, decentralised means of power generation that can complement the composition of the electricity generation mix. Dynamic tools capable of handling transient system behaviour are required to assess MCHP efficiency beyond a mere static analysis based on steady‐state design parameters. Using a simulation of a cogeneration system, we combine exergetic definitions for different operational system states to quantify the overall system efficiency continuously over the whole period of operation. The concept of exergy allows direct comparison of different forms of energy. A sensitivity analysis was performed where we quantified the effect on MCHP overall performance under varying engine rotational speed, thermal energy storage size and fluid storage temperature in a range of MCHP simulations. We found that the exergetic quantity of natural gas used by the MCHP decreased slightly at higher engine speeds (?2% to ?4%). While the total amount of electricity generated is almost constant across the range of different engine output, more thermal exergy (up to +21%) can be recovered when the engine is operating at elevated speeds. Furthermore, selection of specific optimal thermal storage fluid temperatures can aid in improving system efficiency. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

Two experiments (modeled after J. Deese's 1959 study) revealed remarkable levels of false recall and false recognition in a list learning paradigm. In Exp 1, Ss studied lists of 12 words (e.g., bed, rest, awake); each list was composed of associates of 1 nonpresented word (e.g., sleep). On immediate free recall tests, the nonpresented associates were recalled 40% of the time and were later recognized with high confidence. In Exp 2, a false recall rate of 55% was obtained with an expanded set of lists, and on a later recognition test, Ss produced false alarms to these items at a rate comparable to the hit rate. The act of recall enhanced later remembering of both studied and nonstudied material. The results reveal a powerful illusion of memory: People remember events that never happened.

Comments on 2 unrelated features of the American Psychologist's "Summary Report of Journal Operations": rejection rates and number of subscribers. The rejection rates presented in the report are inflated and a more plausible interpretation of the rejection rates is provided. Moreover, the number of subscribers to the American Psychological Association primary journals is actually lower than the data suggest.

Explicit measures of human memory, such as recall or recognition, reflect conscious recollection of the past. Implicit tests of retention measure transfer (or priming) from past experience on tasks that do not require conscious recollection of recent experiences for their performance. The article reviews research on the relation between explicit and implicit memory. The evidence points to substantial differences between standard explicit and implicit tests, because many variables create dissociations between these tests. For example, although pictures are remembered better than words on explicit tests, words produce more priming than do pictures on several implicit tests. These dissociations may implicate different memory systems that subserve distinct memorial functions, but the present argument is that many dissociations can be understood by appealing to general principles that apply to both explicit and implicit tests. Phenomena studied under the rubric of implicit memory may have important implications in many other fields, including social cognition, problem solving, and cognitive development.

Attempts were made to define which fatty acid (2∶0 to 18∶1) was optimally oxidized by isolated colonocytes (colonic epithelial
cells) and to select inhibitors of fatty acid oxidation which would be analogous in their action to the inhibition of fatty
acid oxidation observed in colonocytes involved with ulcerative colitis. Isolated colonic epithelial cells of Sprague-Dawley
rats were used with 2-mercaptoacetate, dichloroacetate, 3-mercaptopropionate, 4-mercaptobutyrate, 4-sulfatebutyrate, 2-bromobutyrate,
sulfite ions and nitrite ions. n-Butyrate (4∶0) was maximmaly oxidized to CO2 and ketone bodies (mean value 5.46 μmol/min/g dry wt). Oxidation of butyrate to CO2 was diminished by 2-bromobutyrate, sulfite ions and all mercapto fatty acids. Both fatty acid oxidation and glucose oxidation
were significantly inhibited by 2-bromobutyrate, while mercapto fatty acids and sulfite inhibited fatty acid oxidation (p<0.01)
without significantly changing glucose oxidation. Observation with 2-mercaptoacetate and sulfite correlate with early changes
of fatty acid oxidation observed in cases of ulcerative colitis, and warrant further study with isolated colonocytes of man. 相似文献

Healthy younger and older adults and individuals with very mild or mild dementia of the Alzheimer type (DAT) listened to and read fictional stories containing correct and incorrect facts about the world. Of interest was their use of this story information to answer questions on a later test of general world knowledge. Prior exposure to relatively well-known facts boosted all subjects' ability to correctly answer general knowledge questions. Reading incorrect facts in the stories led to misinformation effects in healthy older adults (although these effects were smaller than those observed in younger adults). DAT individuals showed reduced effects of story exposure; effects were greatest in a situation that reminded DAT individuals that the stories might provide the answers to the questions. Benefits of story reading depended on activation of the semantic network, whereas costs of story reading were more dependent on episodic memory processes.

Four verbal implicit memory tests, word identification, word stem completion, word fragment completion, and anagram solution, were directly compared in 1 experiment and were contrasted with free recall. On all implicit tests, priming was greatest from prior visual presentation of words, less (but significant) from auditory presentation, and least from pictorial presentations. Typefont did not affect priming. In free recall, pictures were recalled better than words. The 4 implicit tests all largely index perceptual (lexical) operations in recognizing words, or visual word form representations. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

For some years a lot of effort has been put into improving the human-computer interface in CAD-systems. After a short introduction on input problems in design processes, some of this work is reported here as well as a fairly new method, handsketching. In the third part of this paper a special system called CASUS is thoroughly explained from the user's point of view. A fourth part deals with the authors' conviction that psychological theories and methods are necessary in order to create still better interfaces. In the last chapter the system presented with all its interface features is compared to some human factor considerations discussed before. No attention is paid to the fact that very often the quality of work is changed by introducing CAD-systems. Though the designer's situation can be very often improved much more by designing his entire work, this paper lays claim only to designing a tool for the designer's hand. 相似文献
