Previous research found that cognitive training increases the Big Five personality trait Openness to Experience during and some weeks after the intervention. The present study investigated whether long‐term changes happen in Openness to Experience and other personality traits after an extensive cognitive training of memory and perceptual speed. The intervention group consisted of 204 adults (20–31 years and 65–80 years; 50% female) who received daily 1‐hour cognitive training sessions for about 100 days. The control group consisted of 86 adults (21–29 years and 65–82 years; 51% female) who received no cognitive training. All participants answered the NEO Five‐Factor Inventory before and 2 years after the cognitive training. Latent change models were applied that controlled for age group (young vs. old) and gender. In the long run, the cognitive training did not affect changes in any facet of Openness to Experience. This was true for young and old participants as well as for men and women. Instead, the cognitive training lowered the general increase of Conscientiousness. Even an extensive cognitive training on memory and perceptual speed does not serve as a sufficient intervention for enduring changes in Openness to Experiences or one of its facets. 相似文献

In their excitement at using the human genome project to uncover the functions of specific genes, researchers have often ignored
one fundamental factor: the gradual process of ontogenetic development. The view that there might be a gene for spatial cognition
or language has emanated from a focus on the structure of the adult brain in neuropsychological patients whose brains were
fully and normally developed until their brain insult. The developing brain is very different. It starts out highly interconnected across regions and is neither localized nor specialized at birth,
allowing interaction with the environment to play an important role in gene expression and the ultimate cognitive phenotype.
This article takes a neuro constructivist perspective, arguing that domain-specific end states can stem from more domain-general
start states, that associations may turn out to be as informative as dissociations, and that genetic mutations that alter
the trajectory of ontogenetic development can inform nature/nurture debates. 相似文献

Part-list cuing--the detrimental effect of the presentation of a subset of learned items on recall of the remaining items--was examined in amnesic patients and healthy control subjects. Subjects studied two types of categorized item lists: lists in which each category consisted of strong and moderate items and lists in which each category consisted of weak and moderate items. The subjects recalled a category's strong and weak items in either the presence of or absence of the moderate items serving as retrieval cues. In healthy subjects, part-list cuing impaired recall of the strong items but not of the weak items; in amnesics, part-list cuing impaired recall of both types of items. Part-list cuing is often attributed to a change in the retrieval process from a more effective one when cues are absent to a less effective one when they are present. On the basis of this view, our results indicate that part-list cuing causes a stronger retrieval inefficiency in amnesic patients than in healthy people. 相似文献

The authors examined religious practices of Hindus in the United States and developed measures of their religious pathways. Based on reviews of the psychology of religion, Hindu literature, and interviews with Hindus (N=15), 4 religious pathways were identified: devotion, ethical action, knowledge, and physical restraint/yoga. Items reflecting these pathways were generated and administered to a pilot sample (N=42) and then mailed to a sample across the United States (N=182). Consistent with Hindu theology, participants endorsed 4 religious pathways. Results indicated that the measures of the religious pathways possessed adequate psychometric properties and were predictive of mental and physical well-being. Additional findings emphasized the need to attend to age, marital status, and acculturation when studying religious practices among Hindus. 相似文献

In the present experiments, we investigated the effects of several commonly employed antiepileptic drugs on the performance
of adult rats in a Morris water maze task. We found that phenytoin treatment produced the most deleterious performance impairments
across all days of training, and that these performance deficits are not likely due to any general sensorimotor impairments.
Carbamazepine had milder, but detectable negative effects, as carbamazepine-treated animals exhibited initial acquisition
deficits, but rapidly achieved escape levels comparable to controls. In marked contrast, valproate and ethosuximide had no
detectable effects on learning in the water maze. These results parallel previous findings in rats treated with these compounds
and tested in an instrumental learning task, and are in general agreement with the human clinical literature. To the extent
that one might wish to minimize learning deficits associated with maintenance on antiepileptic drugs, phenytoin is definitely
not the treatment of choice, while valproate or ethosuximide are apparently much less disruptive. 相似文献

An artificial grammar learning experiment is reported which investigated whether three types of information are learned during
this kind of task: information about the positions of single letters, about fragments of training strings, and about entire
training strings. Results indicate that participants primarily learned information about string fragments and, to a lesser
extent, information about positions of letters. Two connectionist models, an autoassociator and a simple recurrent network
(SRN), were tested on their ability to account for these results. In the autoassociator simulations, similarity of test items
to entire training items had a large effect, which was at variance with the experimental results. The results of the SRN simulations
almost perfectly matched the experimental ones.

The presence of a diagnosable Axis I psychiatric disorder predicted significantly (P < 0.001) lower likelihood of significant improvement among 90 irritable bowel syndrome patients given cognitive and behavioral treatments to help the disorder. Other psychological tests, including the MMPI, BDI, STAI, as well as demographic variables, failed to yield significant prediction. 相似文献

Native speakers of American English and of German listened to a passage several minutes in duration in each language and reported occurrence and duration of pauses. Subjects overestimated occurrence (false positives) and understimated duration. Overall analyses of variance indicated that Germans reported a higher percentage of pauses than Americans; that a higher percentage of pauses was reported in native than in nonnative passages; that Americans reported a higher percentage of pauses in English passages, whereas Germans' percentages were the same in both languages; that American women reported more false positives than American men, whereas German men reported more than German women; and that Americans and Germans both reported more false positives in English than in German. Detailed analyses of the individual passages yielded reliable differences between Germans and Americans in their reports of pauses in three duration brackets: .3;,<1.0;1.0 sec. Pause reports of this kind diverge from objectively measured pause data as a function of a number of independent variables and are therefore not to be trusted as objective estimates of either pause occurrence or pause duration. 相似文献
