Using a within-subjects design, we administered to 83 naval pilots and flight officers computer-based and paper-based tests to assess recognition of aircraft silhouettes in order to determine the relative reliabilities and validities of these two measurement modes. Estimates of internal consistencies, equivalences, and discriminative validities were computed for multiple performance measures. It was established that the relative reliabilities and validities derived for these two assessment schemes were contingent on the employed multivariate measurement criteria, that is, percentage correct responses, average response latency, and average degree of confidence in recognition judgments, as well as the statistical criteria used to ascertain the comparative quality of these two modes of testing. 相似文献

The present work was aimed at investigating whether the flanker compatibility effect can be eliminated by means of a posthypnotic suggestion influencing attentional focusing. In Experiment 1, participants who scored high and low on hypnotic susceptibility performed the flanker compatibility task when naturally awake and when under a posthypnotic suggestion aimed at increasing the target's discriminability from the flankers. Results showed that the posthypnotic suggestion effectively eliminated the flanker compatibility effect in highly susceptible participants, whereas low-susceptibility participants did not show any reduction in the effect. In Experiment 2, highly susceptible participants performed the task after receiving a suggestion but without the induction of hypnosis. Results showed that the suggestion alone was not sufficient to reduce the flanker compatibility effect. These results support the view that in highly susceptible participants, hypnotic suggestion can influence the ability to focus on relevant information. 相似文献

Twelve pigeons were exposed to negative automaintenance contingencies for 17-27 sessions immediately after brief (14-16 sessions) or extended (168-237 sessions) exposure to positive automaintenance contingencies, or after 4-10 sessions of instrumental training. In all conditions, negative automaintenance contingencies virtually eliminated responding, reducing response rates to an average 1.3 responses per min. This reduction in response rate was validated by a model of transition between early and late response rates that assumed exponential transition of rates from one set of contingencies to the next. The model faithfully reproduced cumulative records, and yielded estimates of terminal rates under negative automaintenance that were close to operant level. 相似文献

To ascertain the amount of association between cognitive complexity and cerebral sensory interaction, visual, auditory and bimodal event-related potentials were recorded from 50 right-handed Caucasian males. Sensory interaction indices were derived for these Ss who had taken the Role Construct Repertory Test of cognitive complexity. Product-moment correlations were computed between sensory interaction indices for eight cerebral and cognitive complexity test scores. Sensory interaction for one left and all right hemisphere regions was significantly related to cognitive complexity. As sensory suppression lessened, cognitive complexity decreased. The results substantiated the theory that the visual-imaginal and the auditory-verbal representational systems are implicated in cognitive complexity. The extent to which the cortex can inhibit or attenuate the interaction between these dual symbol systems is associated with intricate cognitive processing. 相似文献

In follow-up to a large-scale ethics survey of neuroscientists whose research involves neuroimaging, brain stimulation and imaging genetics, we conducted focus groups and interviews to explore their sense of responsibility about integrating ethics into neuroimaging and readiness to adopt new ethics strategies as part of their research. Safety, trust and virtue were key motivators for incorporating ethics into neuroimaging research. Managing incidental findings emerged as a predominant daily challenge for faculty, while student reports focused on the malleability of neuroimaging data and scientific integrity. The most frequently cited barrier was time and administrative burden associated with the ethics review process. Lack of scholarly training in ethics also emerged as a major barrier. Participants constructively offered remedies to these challenges: development and dissemination of best practices and standardized ethics review for minimally invasive neuroimaging protocols. Students in particular, urged changes to curricula to include early, focused training in ethics. 相似文献

The aim of the present study was to assess the factor structure of the Italian version of the Beck Hopelessness Scale (BHS) in a large sample of patients with medical conditions, comparing four different models proposed previously in the literature. Participants were 514 Italian adult patients with diagnoses of chronic daily headache, type 1 (insulin-dependent) or type 2 diabetes mellitus, epilepsy, open-angle glaucoma, human immunodeficiency virus infection, and women admitted for childbirth to a Department of Fetal–Maternal Medicine. All the patients were administered the BHS during routine visits. Confirmatory factor analyses were used to compare four models using several fit indices. The one-construct two-method model (i.e., the BHS measures one substantive hopelessness construct plus artifacts due to negative–positive item polarity) had the best fit indices and was more parsimonious than other models. The BHS seems to be a unidimensional measure of hopelessness, although there may be artifacts due to item polarity (i.e., positively and negatively worded items). Hopelessness scores differed in patients with particular medical diseases, with higher scores in conditions such as chronic daily headache and diabetes, and lower scores in patients positive for the human immunodeficiency virus (HIV), and with open-angle glaucoma or epilepsy. 相似文献

In the past 20 years, many studies in the cognitive neurosciences have analyzed human ability to navigate in recently learned and familiar environments by investigating the cognitive processes involved in successful navigation. In this study, we reviewed the main experimental paradigms and made a cognitive-oriented meta-analysis of fMRI studies of human navigation to underline the importance of the experimental designs and cognitive tasks used to assess navigational skills. We performed a general activation likelihood estimation (ALE) meta-analysis of 66 fMRI experiments to identify the neural substrates underpinning general aspects of human navigation. Four individual ALE analyses were performed to identify the neural substrates of different experimental paradigms (i.e., familiar vs. recently learned environments) and different navigational strategies (allocentric vs. egocentric). Results of the general ALE analysis highlighted a wide network of areas with clusters in the occipital, parietal, frontal and temporal lobes, especially in the parahippocampal cortex. Familiar environments seem to be processed by an extended temporal-frontal network, whereas recently learned environments require activation in the parahippocampal cortex and the parietal and occipital lobes. Allocentric strategy is subtended by the same areas as egocentric strategy, but the latter elicits greater activation in the right precuneus, middle occipital lobe and angular gyrus. Our results suggest that different neural correlates are involved in recalling a well-learned or recently acquired environment and that different networks of areas subtend egocentric and allocentric strategies. 相似文献

The clock drawing test has been routinely administered by many neuropsychologists as part of their testing battery with the adult population. Our study investigated the development of clock face drawing in normal children ages 6 to 12 years. Conceptualization of time and construction of the clock face were assessed by an adapted scoring system developed as part of the investigation. As a group, the results indicated an upward progression with regard to the concept of time through age 8 and clock construction through age 12. Results further demonstrated that number reversals were more frequent among left-handers but were no longer evident by age 7 regardless of handedness. It also was determined that left visuospatial neglect specific to the upper quadrant was relatively common in 6- and 7-year olds but not evidenced by age 8. Given the pattern of the findings, it is likely that the neglect was secondary to poor planning and not a visuo-spatial deficit. In general, development of clock face drawing most closely paralleled that of frontal lobe maturation. Implications of these findings and the usefulness of clock face drawing with the pediatric population are presented. 相似文献

According to moral foundations theory (Haidt & Joseph, 2004), five foundations are central to moral intuition. The two individualizing foundations—harm/care and fairness/reciprocity—hinge on the rights of the individual, whereas the three binding foundations—in‐group/loyalty, authority/respect, and purity/sanctity—focus on communal bonds. Recent work suggests that reliance on the various foundations varies as a function of sociopolitical orientation: liberals consistently rely on the individualizing foundations, whereas conservatives rely on both the individualizing and binding foundations. In an effort to further explore the relationship between sociopolitical orientation and morality, we argue that only certain types of sociopolitical attitudes and beliefs should relate to each cluster of foundations. Drawing on dual‐process models of social and political attitudes, we demonstrate that the individualizing foundations are aligned with attitudes and beliefs relevant to preferences for equality versus inequality (i.e., SDO and competitive‐jungle beliefs), whereas the binding foundations are aligned with attitudes and beliefs relevant to preferences for openness versus social conformity (i.e., RWA and dangerous‐world beliefs). We conclude by discussing the consequences of these findings for our understanding of the relationship between sociopolitical and moral orientations. 相似文献
