Extraversion and emotional reactivity 总被引:1,自引:0,他引:1
Six mood induction studies and a meta-analysis were conducted to test 2 models of the extraversion-pleasant affect relation. The affect-level model suggests that extraverts should be happier than introverts in both neutral and positive mood conditions. The reactivity model posits that extraverts react particularly strongly to pleasant stimuli and that they should be happier than introverts only in positive conditions. In all studies, extraverts failed to exhibit greater emotional reactivity when pleasantness items were analyzed. When activated positive affect items were analyzed, results were mixed. The meta-analysis confirmed that there is only a slight reactivity effect overall, and this effect emerges only in activated positive affect items. Furthermore, the meta-analysis showed that the correlation in neutral conditions is strong enough to support the affect-level model. 相似文献

An illusory correlation paradigm was used to compare high and low socially anxious individuals' initial, on-line and a posteriori covariation estimates between emotional faces and aversive, pleasant and neutral outcomes. Overall, participants demonstrated an initial expectancy bias for aversive outcomes following angry faces, and pleasant outcomes following happy faces. On-line expectancy biases indicated that initial biases were extinguished during the task, with the exception of low socially anxious individuals who continued to over-associate positive social cues with pleasant outcomes. In addition to lacking this protective positive on-line bias, the high social anxiety group reported retrospectively more negative social cues than the low socially anxious group. Findings are discussed in relation to similar evidence from recent interpretive and memory paradigms. 相似文献

The present study used two cognitive tasks--a text comprehension task and a homophone task--to investigate whether clinically depressed individuals have a negative bias when interpreting ambiguous information. Previous research indicates that both tasks are sensitive to anxiety-related interpretive biases, and that the former is less prone to response bias effects. Negative memory biases were also assessed. Results showed that, compared with normal controls, depressed individuals made more negative interpretations on the homophone task, and they also showed an enhanced negative recall bias. However, the groups did not differ in interpretative bias on the text comprehension task. Possible explanations of the results are discussed, including the potential influences of self-referent processing and response bias. 相似文献

The time course of attentional biases for spider stimuli was assessed in two groups of individuals with high or low levels of spider fear. Pairs of photographs of spiders and cats were presented in a visual probe task with three exposure durations: 200, 500 and 2000 ms. Results indicated greater attentional bias for spider stimuli in high fear, than in low fear, individuals in the 200 ms condition. The attentional bias in the high fear group significantly reduced as stimulus exposure duration increased, with no significant biases found in the longer exposure conditions. Results support the view that high fear is associated with an enhanced initial attentional bias for fear-relevant stimuli, but that this attentional bias is not maintained over time. 相似文献

False recognition following presentation of semantically related and phonologically related word lists was evaluated in 8-, 11-, and 13-year-olds. Children heard lists of words that were either semantic (e.g., bed, rest, wake ...) or phonological associates (e.g., pole, bowl, hole ...) of a critical unpresented word (e.g., sleep, roll), respectively. A semantic false memory was defined as false recognition of a semantically related but unpresented word. A phonological false memory was defined as false recognition of a phonologically related but unpresented word. False memories in the two tasks showed opposite developmental trends, increasing with age for semantic relatedness and decreasing with age for phonological relatedness. 相似文献

Motor abnormalities have long been a focus in discussions of schizophrenia. The present study used a newly developed line drawing task to examine fine motor performance and psychometrically assessed schizotypy in a large, randomly ascertained sample of young adults (N = 120) with no history of psychosis. Poor motor performance on the line drawing task, indexed by root-mean-square error (RMS), was significantly related to 4 separate psychometric measures of schizotypy in the overall sample. The psychometric schizotypy-RMS association remained significant for 2 of the schizotypy measures even when the effects of intellectual functioning, mental state factors, and sustained attention were statistically controlled in a regression analysis. The status of the line drawing index as a schizophrenia liability measure is discussed. 相似文献

Two studies investigated the effects of conditioning to masked stimuli on visuospatial attention. During the conditioning phase, masked snakes and spiders were paired with a burst of white noise, or paired with an innocuous tone, in the conditioned stimulus (CS)+ and CS- conditions, respectively. Attentional allocation to the CSs was then assessed with a visual probe task, in which the CSs were presented unmasked (Experiment 1) or both unmasked and masked (Experiment 2), together with fear-irrelevant control stimuli (flowers and mushrooms). In Experiment 1, participants preferentially allocated attention to CS+ relative to control stimuli. Experiment 2 suggested that this attentional bias depended on the perceived aversiveness of the unconditioned stimulus and did not require conscious recognition of the CSs during both acquisition and expression. 相似文献

We report the results of a 4-year-long study of capuchin monkeys (Cebus apella ) on concurrent three-way classification and linear size seriation tasks using explicit ordering procedures, requiring subjects
to select icons displayed on touch screens rather than manipulate and sort actual objects into groups. The results indicate
that C. apella is competent to classify nine items concurrently, first into three disjoint classes where class exemplars are identical to
one another, then into three reciprocal classes which share common exemplar (size) features. In the final phase we compare
the relative efficiency of executive control under conditions where both hierarchical and/or linear organization can be utilized.
Whilst this shows a superiority of categorical based size seriation for a nine item test set suggesting an adaptive advantage
for hierarchical over linear organization, Cebus nevertheless achieved high levels of principled linear size seriation with sequence lengths not normally achieved by children
below the age of six years. 相似文献

IBM PCs and compatibles are increasingly used in psychological research for tachistoscopic tasks, which require precise control of timing of stimulus durations and accurate measurement of response latencies. The application of MEL in such research is discussed; several precautions which influence stimulus timing are noted, and some data on measurement error with keypress responses are presented. 相似文献

Kaplan (1977) proposes a neo-Fregean theory of demonstratives which, despite its departure from a certain problematic Fregean thesis, I argue, ultimately founders on account of its failure to give up the Fregean desideratum of a semantic theory that it provide an account of cognitive significance. I explain why Kaplan's (1989) afterthoughts don't remedy this defect. Finally, I sketch an alternative nonsolipsistic picture of demonstrative reference which idealizes away from an agent's narrowly characterizable psychological state, and instead relies on the robust multiply realizable relation between the skilled agent and demonstrated object.When the unclean spirit has gone out of a person, it wanders through waterless regions looking for a resting place, but it finds none. Then it says, 'I will return to my house from which I came.' When it comes, it finds it empty, swept, and put in order. Then it goes and brings along seven other spirits more evil than itself, and they enter and live there; and the last state of that person is worse than the first. So will it be also with this evil generation.– attributed to Jesus (Matthew 12:43-45, New Revised Standard Version of the Bible) 相似文献
