A number of methodological features were incorporated in a paradigm designed to maximize the likelihood of finding reliable event-related potential (ERP) signs of functional specializations between and within the cerebral hemispheres. Every subject was more accurate in identifying words presented to the right than to the left visual field. The morphology of the ERPs elicited by these words varied considerably as a function of electrode position both within and between the hemispheres. Amplitude asymmetries of ERP components recorded from occipital regions of the two hemispheres varied systematically with the position of the word in the visual field. On the other hand, ERPs from more anterior (temporal and frontal) regions displayed large asymmetries which were in the same direction regardless of the visual field of word presentation. The most prominent such asymmetry was in the negativity in the region 300–500 msec (N410) which was larger in the left than the right hemisphere in every subject. These results demonstrate that in this paradigm which demands specialized language processing ERPs are sensitive to aspects of cerebral organization both within and between the two hemispheres. 相似文献
1150 Hungarian boys and 1035 girls were given the Junior Eysenck Personality Questionnaire translated into Hungarian. Product-moment correlations were factored by principal components methods, rotated by Varimax and then obliquely by Promax. Thirteen extra items, added for substitution if necessary, were included in this analysis. Very close agreement between the responses of British and Hungarian children were found for the Lie or Social Desirability scale, good agreement for Extraversion but less satisfactory agreement for Neuroticism and Psychoticism items. It is argued that the strength of the Lie score could well have interfered with the true responses for the other dimensions. Means and standard deviations for British and Hungarian children are given on scales comprised of items both groups have in common on their respective scoring keys, this being the only way the means can be compared. 相似文献

In this article, I argue for the need of more use of exploratory techniques to identify dynamics in social interactions. I describe several approaches as they are applied to multivariate time series data. The first approach is an algorithm that searches for periods of variability and stability at the individual level as well as for patterns of overlap in such periods between the two individuals in a couple. These patterns describe the daily ups and downs in the couples' affect and are predictive of the state of the couples 1 to 2 years later. The second approach, hierarchical segmentation, is based on the idea of partitioning the time series in segments with distinct data patterns. In the case of data from dyads, as in the illustration, the patterns can be compared in terms of coherence between the 2 individuals in the dyad. The third approach is based on network analysis, and its use is shown as a method to examine data transitions at the individual and dyadic level as well as system-wide coherence in multivariate systems. For each approach, I provide examples of its use with empirical data. The article ends with general guidelines and recommendations for researchers interested in using exploratory methods as a way to examine psychological processes. 相似文献
Objective: Weight-based discrimination negatively influences health, potentially via increased willingness to engage in unhealthful behaviours. This study examines whether the provision of genomic obesity information in a clinical context can lead to less willingness to engage in unhealthy eating and alcohol consumption through a mediated process including reduced perceptions of blame and discrimination.
Design: A total of 201 overweight or obese women aged 20–50 interacted with a virtual physician in a simulated clinical primary care environment, which included physician-delivered information that emphasised either genomic or behavioural underpinnings of weight and weight loss.
Main Outcome Measures: Perceived blame and weight discrimination from the doctor, and willingness to eat unhealthy foods and consume alcohol.
Results: Controlling for BMI and race, participants who received genomic information perceived less blame from the doctor than participants who received behavioural information. In a serial multiple mediation model, reduced perceived blame was associated with less perceived discrimination, and in turn, lower willingness to eat unhealthy foods and drink alcohol.
Conclusion: Providing patients with genomic information about weight and weight loss may positively influence interpersonal dynamics between patients and providers by reducing perceived blame and perceived discrimination. These improved dynamics, in turn, positively influence health cognitions. 相似文献
Given the growing interest in the study of subjective well-being as a measure of social progress, instruments that produce valid and reliable scores and that can be used within and across countries are needed. The aim of the present study was to analyze the measurement equivalence of the Day Reconstruction Method in its brief version, using nationally representative samples from Finland, Poland, and Spain obtained within the COURAGE in Europe project. The goodness-of-fit of a two-correlated-factors model and the reliability of the scores obtained were assessed. Cross-country invariance was tested employing a multiple group confirmatory factor analysis, through sequential constraint imposition. In each country, measurement invariance was tested across time frames (morning, afternoon and evening) and days of the week (weekday and weekend). The results found support for the hypothesis of a two-correlated-factors (positive and negative affect) structure; the reliability of the positive, the negative and the net affect scores showed appropriate values. A high equivalence across the three national samples was found: all items except one showed strong measurement invariance indicating that respondents from Finland, Poland, and Spain attribute the same meaning to the latent construct under study, and the levels of the underlying items are equal in all three countries. Similar results were found for the measurement equivalence across time frames and days of the week. Our findings support the assumption of comparability across the different samples considered; in general, higher positive affect and lower negative affect were found in Finland, in the evening and at the weekend. 相似文献
