When depression alternates with mania, as in a bipolar affective disorder, creativity might be enhanced. To investigate this, we employed a single‐subject design, looking at both affective space and the spectral covariation of mood and creativity in a participant presenting with bipolar affective disorder. The study was conducted over a period of 54 days, and employed a standard measure of mood (the Brief Mood Introspection Scale) and a standard task of creativity (Alternative Uses Task). Both positive affect and negative affect appear to be somewhat undifferentiated for this participant, and her mood space does not conform to that described by the accepted major dimensions of Arousal and Pleasure. Conceivably, this is because of her rapid mood fluctuations. A 2.7‐day periodicity was found for Tired, Peppy, Nervous, and Calm, on the one hand, and ideational fluency, ideational flexibility, and originality, on the other. In addition, a 9‐day periodicity was common to Happy, Sad, and Gloomy—all three affects clustering in the same affective space—together with both ideational flexibility and originality. This finding brings into question the relationship between creativity and both positive and negative mood. 相似文献

A functional region of left fusiform gyrus termed “the visual word form area” (VWFA) develops during reading acquisition to respond more strongly to printed words than to other visual stimuli. Here, we examined responses to letters among 5‐ and 6‐year‐old early kindergarten children (N = 48) with little or no school‐based reading instruction who varied in their reading ability. We used functional magnetic resonance imaging (fMRI) to measure responses to individual letters, false fonts, and faces in left and right fusiform gyri. We then evaluated whether signal change and size (spatial extent) of letter‐sensitive cortex (greater activation for letters versus faces) and letter‐specific cortex (greater activation for letters versus false fonts) in these regions related to (a) standardized measures of word‐reading ability and (b) signal change and size of face‐sensitive cortex (fusiform face area or FFA; greater activation for faces versus letters). Greater letter specificity, but not letter sensitivity, in left fusiform gyrus correlated positively with word reading scores. Across children, in the left fusiform gyrus, greater size of letter‐sensitive cortex correlated with lesser size of FFA. These findings are the first to suggest that in beginning readers, development of letter responsivity in left fusiform cortex is associated with both better reading ability and also a reduction of the size of left FFA that may result in right‐hemisphere dominance for face perception. 相似文献

The primary goal of the present study was to investigate how the mental representations of value conflicts are restructured after a decision. A value conflict exists if a chosen alternative is less attractive than a non-chosen alternative on one important attribute when a decision is made. In order to follow up earlier field studies with no experimental control over value conflicts, the present study induced value conflicts in the laboratory. This was done through associating the more attractive of two alternatives with a smaller probability of success. The first hypothesis was that consolidation of value conflict attributes should follow the same pattern when the conflict is controlled experimentally as in earlier studies of real-life decisions. The second hypothesis was that consolidation should be weaker in a non-consequential laboratory study than in the earlier real-life studies. The third hypothesis was that stronger value conflicts (that is, value conflict on more important attributes) lead to greater consolidation effects than weaker value conflicts. The results showed that participants consolidated the value conflicts in the same way as in real-life decisions with the difference that also less important attributes were consolidated in the present study. However, the consolidation effects were not so strong that they caused advantage reversals on a conflict attribute, as in the earlier field studies with real outcomes and consequences. There was no relationship between strength of conflict and consolidation. The fact that no advantage reversals were registered leads to questions about the ecological validity of laboratory studies of non-consequential decision making. 相似文献

Three studies investigated decision makers' memory representations of choice alternatives in most important real-life decisions. In Study 1, each participant recalled the most important decision that she or he had ever made and rated to what degree a number of characteristics could describe the decisions. In Study 2, the participants were asked to think about an important decision that they had made during the last 7-10 days. In Study 3, the memory representations of decisions of a group of action-oriented participants were compared with those of a group of state-oriented participants (Kuhl, 1983). Characteristics related to standard decision theory, like consequences, values, and likelihood, had high ratings of applicability as well as affect/feeling. When testing the applicability of a circumplex model, the fuzzy-trace theory of memory, and differences between state- and action-oriented decision makers, we found (1) that there was no support for the circumplex model of emotions. Instead, an important decision problem was characterised by both positive and negative affect/emotion and thus, a bipolar mapping was found inadequate; (2) that a comparison of abstract and concrete aspects showed that the abstract characteristics scored higher, thereby supporting the fuzzy-trace theory; and (3) that the prediction that action-oriented participants would score higher than state-oriented participants on the characteristic of activity was not supported. However, state-oriented decision makers rated passivity higher than action-oriented decision makers for the important decision of leaving a partner. State-oriented decision makers used perceptual/cognitive scenario representations to a greater extent than action-oriented participants. Finally, it was stressed that in the development of decision theories it is essential to find theoretical representations as close as possible to how decision makers themselves represent the decisions. The method used in this contribution is focused on the role of memory in decision making and gives further insights into how important real-life decisions are represented by different decision makers. 相似文献

The present investigation concerns the integrity of a primary mental function, the egocentric frame of reference and the sense of polarity of one's own head. The visually perceived eye level (VPEL) and the subjective antero-posterior axis of the head were measured by means of a visual indicator in darkness during two stimulus conditions: static pitch (sagittal-plane) tilting in the 1-g environment and gondola centrifugation (2G). It is demonstrated that an increase in the magnitude of the gravitoinertial (G) force, acting in the direction of the head and body long (z) axis, causes a substantial change not only in the VPEL but also in the perceived direction of the antero-posterior axis of the head. 相似文献

The present study investigated a possible connection between speech processing and cochlear function. Twenty-two subjects with age range from 18 to 39, balanced for gender with normal hearing and without any known neurological condition, were tested with the dichotic listening (DL) test, in which listeners were asked to identify CV-syllables in a nonforced, and also attention-right, and attention-left condition. Transient evoked otoacoustic emissions (TEOAEs) were recorded for both ears, with and without the presentation of contralateral broadband noise. The main finding was a strong negative correlation between language laterality as measured with the dichotic listening task and of the TEOAE responses. The findings support a hypothesis of shared variance between central and peripheral auditory lateralities, and contribute to the attentional theory of auditory lateralization. The results have implications for the understanding of the cortico-fugal efferent control of cochlear activity. 相似文献

This article aims at exploring the means for and hope of overcoming trauma, that is, violent emotional shock, through the use of humor and theology in conjunction. Both humor and the experience of the hope of some kind of redemption are ways of transcending the given. But is such overcoming possible without illusion or escapism? These issues are explored through the psychotheological perspectives on humor in the psychoanalyst Sigmund Freud and the Swedish archbishop and theologian Nathan Söderblom. 相似文献

Functional abdominal pain (FAP) and functional dyspepsia (FD) are common in adolescents and associated with low quality of life. Exposure-based cognitive-behavioral therapy (CBT) is efficient for adult and adolescent irritable bowel syndrome (IBS), but has never been evaluated for adolescent FAP/FD. The aim of this study was to evaluate the feasibility and potential efficacy of a novel disorder-specific Internet-delivered CBT (Internet-CBT) for adolescents with FAP or FD, using an uncontrolled open pilot including 31 adolescents. The Internet-CBT consisted of 10 weekly online modules, which focused mainly on exposure to abdominal symptoms. Parents received modules to help them reduce unhelpful parental behaviors. Participants reported the treatment to be credible, and an overall satisfaction with the treatment. Data attrition rate was low (7%) and adherence to treatment was acceptable. We saw a significant and large effect on the primary outcome, pain intensity, at posttreatment (d = 1.20, p < .001) that was further improved after 6 months (d = 1.69, p < .001). Participants also made significant and large improvements on gastrointestinal symptoms (d = 0.84, p < .001) and quality of life (d = 0.84, p < .001) that were sustained or further improved at follow-up 6 months after treatment. This study demonstrated that exposure-based Internet-CBT, tailored for adolescents with FAP or FD, is a feasible treatment that potentially improves pain intensity, gastrointestinal symptoms, and quality of life. 相似文献

When people judge the time that can be saved by increasing the speed of an activity, they are often victims of a time saving bias. That is, they overestimate the time that can be saved by increasing the speed. Judgments of time savings following speed increase when driving follow the Proportion heuristic [Svenson, O. (1970). A functional measurement approach to intuitive estimation as exemplified by estimated time savings. Journal of Experimental Psychology, 86, 204-210]. In a choice between time saving options, this heuristic simplifies to the Ratio rule. The first study tested this rule and found that the Ratio rule predicted incorrect decisions when planning to save traveling time in road traffic. The second study showed that the time saving bias was also present in planning of health care; to specify, in decisions about which one of two clinics to reorganize to save more of the doctors' time for personal contacts with patients. To further test the Ratio rule, Study 3 used a matching procedure in which two decision alternatives were made equal by the participants. The results supported the Ratio rule. Practical implications of the results are discussed including the Planning fallacy. In conclusion, the present set of studies have illustrated a time saving bias and provided evidence explaining why people make systematic errors when judging and deciding about time saved following a speed increase. 相似文献
