The aim of this study was to investigate unconscious priming by the use of a spatial mirror-masking paradigm. Words and nonwords with no under-length letters are mirrored at their horizontal axis. The results are figures of geometric-like forms that contain letters in their upper part. In the three experiments reported in this study, a priming procedure used such mirrored words and nonwords as primes. Participants were ignorant of the nature of the construction of the stimuli. Perceptual reports of the participants revealed that they did not realize that words were hidden in the primes. Nevertheless, they showed priming in all three experiments. Priming effects were replicated with prime-target SOAs of between 1 and 3 s. Functional dissociations were found between ignorant and informed participants. Informed groups showed perceptual and semantic priming, while ignorant groups showed only perceptual priming. 相似文献

The aim of the present study was to determine whether processing of syntactic word information (lemma) is subserved by the same neural substrate as processing of conceptual or word form information (lexeme). We measured BOLD responses in 14 native speakers of German in three different decision tasks, each focussing specifically on one level of lexical processing (conceptual, syntactic, and morpho-phonological). The test parameters were natural gender, grammatical gender, and word form derivation, respectively. Discrimination between words played backwards and complex sounds served as control task. Complex contrasts revealed a functional fractionation of the left inferior frontal gyrus for each level of lexical processing. 相似文献

Dana-Farber Cancer Institute ethics rounds: life-threatening illness and the desire to adopt 总被引:1,自引:0,他引:1
Little MO Moczynski WV Richardson PG Joffe S 《Kennedy Institute of Ethics journal》2005,15(4):385-393
Originally presented during Ethics Rounds at the Dana-Farber Cancer Institute, this commentary on the case of a patient treated for life-threatening cancer explores the responsibilities of health care providers when addressing the patient's desire to adopt a child. 相似文献

Because some features affect the efficiency of visual search even when they are irrelevant to the task, they are thought tocapture attention in a stimulus-driven manner. If such attention shifts are stimulus driven, they should be unaffected by reduced
resources. We added a concurrent auditory task to a traditional attention capture paradigm and found that capture by an irrelevant,
abruptly appearing stimulus (i.e., an onset) was eliminated. In contrast, prioritization of an irrelevant color singleton—a
stimulus that at most receives only mild prioritization in this paradigm—was increased under dual-task conditions. These results
challenge the hypothesis that attention capture by irrelevant features is stimulus driven. Instead, prioritization depends
on and is modulated by the availability of resources. 相似文献

A random sample of hospital administrators throughout the United States was surveyed about their views on the importance of eleven chaplain roles and functions. The 494 respondents fell into three categories: (1) directors of pastoral care departments (N = 132); (2) administrators of hospitals that have a pastoral care department (N = 180); and (3) administrators of hospitals that do not have a pastoral care department (N = 182). All three groups considered all eleven roles to be relatively important, although administrators of hospitals that do not have a pastoral care department gave lower ratings, overall. Meeting the emotional needs of patients and relatives were seen as chaplains most important roles, whereas performing religious rituals and conducting religious services were seen as least important by all three groups. In all but a few instances, the level of importance that administrators assigned to the various roles were positively related to their ratings of their own religiousness and spirituality (r's = .11 to .26, p < .05). 相似文献

Visual skills in airport-security screening 总被引:3,自引:0,他引:3
Abstract— An experiment examined visual performance in a simulated luggage-screening task. Observers participated in five sessions of a task requiring them to search for knives hidden in x-ray images of cluttered bags. Sensitivity and response times improved reliably as a result of practice. Eye movement data revealed that sensitivity increases were produced entirely by changes in observers' ability to recognize target objects, and not by changes in the effectiveness of visual scanning. Moreover, recognition skills were in part stimulus-specific, such that performance was degraded by the introduction of unfamiliar target objects. Implications for screener training are discussed. 相似文献

Two studies examined the influence of coping dispositions (repression, sensitization, and nondefensiveness) and anxiety on the encoding and memory representation of ambiguous threat-related stimuli. In Study 1, memory was tested shortly after encoding. Study 2 contrasted immediate and delayed testing. Repressers showed evidence of "mixed" affective reactions to ambiguous stimuli at encoding, accompanied by weak memory representation of potentially threatening implications of these stimuli. In contrast, sensitizers and anxious individuals manifested a processing bias in favor of threatening implications of ambiguous stimuli. Influences of coping on memory were most pronounced for delayed testing. Anxiety influences on memory were weak. An expectancy-based account of individual differences in processing ambiguous stimuli is discussed. 相似文献

A 2003 comparative study on learning environments at two military officer training sites was replicated using different methodology. Satisfaction with learning environment and with administrative inprocessing was higher at Fort Leavenworth than at Fort Dix. Most students expressed a preference for Fort Leavenworth. Satisfaction with institutional support and educational facilities appears to influence perceived satisfaction with a learning environment and with preference for training sites among senior military officers. 相似文献

Although some features of the "psychological approach" are compelling, its immediate impact as a theoretical framework appears to be limited by somewhat ambiguous key constructs and the lack of appropriate placement vis-a-vis extant conceptual views. 相似文献
