The information gain model argues that participants select alternatives with a larger expected value of information gain. The present study investigated risk aversion in information seeking to examine whether the expected value always determines information-seeking behaviour. For this investigation, we used a scale method selection task in which participants were required to select one of two scales for weighing coins in order to find an underweight coin. Two experiments showed that participants more frequently selected the alternative that provided information gain without risk, although its expected information gain was smaller. This finding indicates the presence of risk aversion in information seeking, suggesting that information-seeking behaviour is affected by risk associated with obtaining information gain. 相似文献

Information Reduction, a performance-enhancing cognitive strategy which develops with practice, is thought to be consciously and abruptly adopted and then applied consistently. Previous investigations used an Alphabet Verification Task where one observation was that not everyone adopts the strategy, but reasons for this are unclear. We demonstrated Information Reduction in three other tasks, confirming that it is not task-specific. Post-testing questionnaires probed verbally expressible knowledge, to gauge conscious awareness of any strategy. Overall, results indicate considerable variation in Information Reduction usage: Some individuals discovered and used the strategy and could verbally express this, others chose not to use it and some appeared to use it without awareness of doing so. Results also indicate that Information Reduction is not consistently applied, suggesting it is less robust than has been proposed. Our results may be better explained by a theory of practice learning which incorporates both data-driven automaticity and top-down controlled processes. 相似文献

Two experiments investigated the effects of mood on the use of global trait information in impression formation tasks. Participants in both experiments formed an impression of a target based on traits and a series of behaviors that were both consistent and inconsistent with the traits. In Experiment 1, participants in happy moods, relative to those in unhappy moods, made impression judgments that reflected the evaluative implications of the trait information to a greater extent than the behaviors, regardless of the order in which they received the information. In Experiment 2, both happy and sad participants engaged in systematic processing, as reflected by the recall data, but only happy participants’ recall of target information was significantly biased by the global trait information they received. These findings are consistent with the affect-as-information model in which affective cues influence the extent to which individuals rely on general knowledge and, importantly, are inconsistent with models that posit that happiness results in reduced motivation or ability to process information carefully. 相似文献

In noun phrase (NP) coordinate constructions (e.g., NP and NP), there is a strong tendency for the syntactic structure of the second conjunct to match that of the first; the second conjunct in such constructions is therefore low in syntactic information. The theory of uniform information density predicts that low‐information syntactic constructions will be counterbalanced by high information in other aspects of that part of the sentence, and high‐information constructions will be counterbalanced by other low‐information components. Three predictions follow: (a) lexical probabilities (measured by N‐gram probabilities and head‐dependent probabilities) will be lower in second conjuncts than first conjuncts; (b) lexical probabilities will be lower in matching second conjuncts (those whose syntactic expansions match the first conjunct) than nonmatching ones; and (c) syntactic repetition should be especially common for low‐frequency NP expansions. Corpus analysis provides support for all three of these predictions. 相似文献

Integrating dual-process models [Chaiken, S., & Trope, Y. (Eds.). (1999). Dual-process theories in social psychology. NewYork: Guilford Press] with work on information sharing and group decision-making [Stasser, G., & Titus, W. (1985). Pooling of unshared information in group decision making: biased information sampling during discussion. Journal of Personality and Social Psychology, 48, 1467-1478.], we predicted that groups with high epistemic motivation engage in more information-driven and less preference-driven interaction, and achieve better decisions. An experiment manipulating process accountability showed that groups under process accountability experienced greater need for more information, repeated unshared information more often, and more often chose the correct decision alternative. Mediation analysis established that epistemic motivation produced high quality decisions because it stimulated systematic information processing. Results also revealed that preference heterogeneity stimulated information-driven interaction and led to higher decision quality. 相似文献

We examined the development of children's understanding of beliefs and emotions in relation to parental talk about the psychological world. We considered the relations between parent–child talk about the emotions of characters depicted in a picture book, false belief understanding and emotion understanding. Seventy-eight primarily Caucasian and middle-class parents and their 3- to 5-year-old children participated (half boys and half girls). The emotions talked about were relatively simple, but the complexity of the situation varied in terms of whether or not an understanding of beliefs was required to understand the emotion. Talk about the belief-dependent aspects of the emotions of picture book characters predicted children's false belief understanding, whereas talk about non-belief-dependent aspects of these emotions predicted children's emotion understanding. We argue that these data suggest that the development of children's understanding of beliefs and emotions is intertwined with learning to talk about the psychological world. 相似文献

This paper discusses the foundations of the theory of socionics, including the rationale behind Aušra Augustinavičiūtė’s model of information processing by the human psyche, and the philosophical thought behind the concept of information metabolism elements. Socionics was developed in the former Soviet Union and may be regarded as analogous to the Myers-Briggs Type Indicator typology of personality. The main goal of this paper is to present socionics to the English-speaking community, in order to better take advantage of its explanatory potential in the fields of interpersonal communication and psychological disorders. Reviewed topics include aspects of Jungian analytical psychology and Kępiński’s information metabolism theory, upon which Augustinavičiūtė based her model. After the model is presented, its theoretical implications are briefly discussed. 相似文献

Effects of emotional valence on attention have been shown to occur even when stimuli are presented outside awareness. The impact of negative valence on stimulus processing has been demonstrated to be particularly salient in anxiety. Therefore, it has been hypothesized that compared to nonanxious individuals, anxious individuals have an enhanced ability to detect the valence of negative stimuli. However, it remains unclear whether anxious individuals are better at identifying the valence of threatening stimuli or, rather, more likely to label ambiguous stimuli as threatening. To investigate these hypotheses, high and low anxious participants categorized lexical stimuli as "safe" or "dangerous." Stimuli were presented at durations that allowed for both conscious (unmasked) and nonconscious (masked) processing. Results show that on masked trials, anxious individuals evidenced an enhanced ability to correctly classify threatening information, whereas nonanxious participants demonstrated an enhanced ability to correctly classify neutral or positive information. Signal detection analyses indicated results were explained by a response bias, whereby anxious individuals were more likely than nonanxious individuals to categorize masked words as threatening and nonanxious individuals were more likely to categorize masked words as nonthreatening. No group differences for nonword stimuli emerged, suggesting that anxiety-related response bias tendencies are activated only after detection of a weak semantic signal. 相似文献

Studies using the modified Stroop colour naming task have provided results consistent with the hypothesis that social phobia is associated with an attentional bias towards negative social-evaluative words. However, these results could also have arisen as a consequence of non-attentional processes. For this reason, the present study uses a modified version of MacLeod et al.'s (J. Abnorm. Psychol. 95 (1986) 15) dot-probe task, which provides a more direct measure of attention. Patients with social phobia (n=28), patients with social phobia and a concurrent depressive disorder (n=33), and non-patients (n=40) were presented with word pairs each consisting of a neutral word and a threat word. The results indicated that patients with social phobia show an attentional bias towards social-threat words while non-patients tend to avoid social-threat words. Patients with social phobia and a concurrent depressive disorder behaved like non-patients, indicating that concurrent depression abolishes the attentional bias. Physical threat words were also included in the study. The main analysis indicated that social phobia is also associated with an attentional bias to physical threat. However, a post hoc analysis (which requires replication) suggested that the physical threat bias might have arisen because some social phobia patients also had another anxiety disorder in which physical concerns are likely to have been prominent. Overall, the results emphasise the importance of assessing comorbidity when investigating attentional biases. 相似文献
