Various demonstrations of “time stamp” effects in the animal learning literature have reinforced the idea that circadian information is encoded as part of a combined internal/external representation of context and that this contextual information is utilized for complex retrieval processes supporting memory. The goal of the present series of experiments is to assess this idea by manipulating training/testing circadian times on a battery of learning and memory tasks commonly used in the rodent. The data obtained from five experiments using four different learning and memory paradigms provide no evidence for “time stamp” effects on place memory, context memory (aversive or appetitive), or S-R habit learning. 相似文献

This ecumenically minded article explores Wesley's understanding of grace both in its relation to experience – inward religion – and in relation to his doctrines of justification and sanctification. Wesley's treatments of justification and sanctification are compared to those of Luther, Calvin and Trent. His unique and ecumenical blending of traditions allowed Wesley to develop a doctrine of grace which offers significant resources to contemporary understandings of Christian life and practice. 相似文献

Effect sizes for experimenting psychologists. 总被引:2,自引:0,他引:2
Ralph L Rosnow 《Revue canadienne de psychologie expérimentale》2003,57(3):221-237
This article describes three families of effect size estimators and their use in situations of general and specific interest to experimenting psychologists. The situations discussed include both between- and within-group (repeated measures) designs. Also described is the counternull statistic, which is useful in preventing common errors of interpretation in null hypothesis significance testing. The emphasis is on correlation (r-type) effect size indicators, but a wide variety of difference-type and ratio-type effect size estimators are also described. 相似文献

Effects of Damage to Right-Hemisphere Brain Structures on Spontaneous Emotional and Social Judgments
Andrea S. Heberlein Ralph Adolphs James W. Pennebaker Daniel Tranel 《Political psychology》2003,24(4):705-726
Recent work in cognitive and social neuroscience has focused on the neural substrates of social judgment. The present study explores the effects of damage to the right-hemisphere somatosensory cortices (RSS), a region known for its role in emotion recognition. Seven subjects with RSS damage were shown a short movie depicting objects that move in socially suggestive ways, a stimulus that typically elicits spontaneous social and emotional attributions from normal subjects. The spontaneous verbal responses of RSS-damaged subjects to this movie were compared to those of normal subjects as well as brain-damaged control subjects; the data were derived using a word count and categorization computer program. This method measures spontaneous social and emotional judgments rather than the more typical rating and labeling measures used in neuropsychological studies of social judgment. As predicted, relative to brain-damaged and normal controls, subjects with RSS damage reacted to the stimulus movie with fewer words in categories describing emotional and social processes, despite using a similar total number of words (and slightly more words describing movement, a control category). These results provide further evidence for the role of the RSS in social/emotional processing and identify a role for the RSS in automatic representation in ourselves of body states of others to foster emotion recognition and social cognition. 相似文献

Psychological constructs can only be measured indirectly in terms overt behavior, often by means of changes in the level of performance on tasks they are presumed to affect. However, the exact relationship between constructs and the tasks they are presumed to affect is usually not known, which often requires non-essential auxiliary assumptions to be added to a psychological model to allow it to contact the data. Signed difference analysis is a method of deriving testable consequences from psychological models under the general assumption that the relationship between task performance and the constructs or combinations of constructs postulated by the model is at least monotonic. The predictions derived using signed difference analysis do not depend upon estimation of either model parameters or explicit functional relationships. In the present paper, the mathematical theory of signed difference analysis is presented and applied to illustrative problems drawn from research in memory, spatial attention, and reading. The relationships between signed difference analysis and related inferential procedures such as conjoint measurement, state-trace analysis, and double dissociation are discussed. 相似文献

Three Pavlovian lick suppression studies with rats were conducted to compare the role of the conditioning context in excitatory backward and forward conditioning. The experiments explored the possibility that excitatory backward conditioning, but not forward conditioning, is mediated by the context. That is, in excitatory backward conditioning, the conditioning context may function as an excitatory mediator, which supports second-order conditioning of the target cue. This possibility contrasts with traditional accounts, which suggests that common processes underlie excitatory backward and forward conditioning. Experiment 1 found that conditioned responding following backward conditioning was attenuated as a result of posttraining extinction of the training context, but the same manipulation elevated responding after forward conditioning. Experiments 2 and 3 found that posttraining and pretraining associative inflation of the context (presenting unsignalled USs) increased conditioned responding to the target of a backward conditioning procedure but either had no effect or reduced responding to the target of a forward conditioning procedure. Thus, excitatory backward and forward conditioning appear to differ in their dependence on the status of the conditioning context. 相似文献
