Scarcity has been found to intensify value, positive or negative, rather than simply enhancing it. Some researchers have proposed that scarcity affects value by increasing how much attention is paid to a stimulus. We conceptualized sustained attention as stronger engagement and operationalized a situation of scarcity by telling participants who were choosing between two objects that the object that was chosen would then be replaced (Replenish) or not replaced (Scarce). To distinguish sustained attention-stronger engagement in a situation of scarcity from grabbing attention (salience from distinctiveness), the choice was between one option with a single instance (solitary-high salience) and a second option with several duplicates (abundant-low salience). We predicted that stronger engagement from a situation of scarcity would, first, intensify the value of the chosen item regardless of whether it was solitary or abundant, with positive items becoming more positive and negative items becoming more negative, and second, the stronger engagement from the situation of scarcity would transfer intensification to another separate object in the same setting. The results of Studies 1 and 2 supported both of these predictions. Study 3 tested a boundary condition for these scarcity–engagement effects in terms of how real participants experienced the choice items to be, where ‘realness’ is another source of engagement strength. As expected, the scarcity–engagement effect on intensifying value was replicated for participants who experienced the activity as real but was eliminated for those who did not. 相似文献

Recent findings suggest that difficulties on small‐scale visuospatial tasks documented in Williams syndrome (WS) also extend to large‐scale space. In particular, individuals with WS often present with difficulties in allocentric spatial coding (encoding relationships between items within an environment or array). This study examined the effect of atypical spatial processing in WS on large‐scale navigational strategies, using a novel 3D virtual environment. During navigation of recently learnt large‐scale space, typically developing (TD) children predominantly rely on the use of a sequential egocentric strategy (recalling the sequence of left–right body turns throughout a route), but become more able to use an allocentric strategy between 5 and 10 years of age. The navigation strategies spontaneously employed by TD children between 5 and 10 years of age and individuals with WS were analysed. The ability to use an allocentric strategy on trials where spatial relational knowledge was required to find the shortest route was also examined. Results showed that, unlike TD children, during spontaneous navigation the WS group did not predominantly employ a sequential egocentric strategy. Instead, individuals with WS followed the path until the correct environmental landmarks were found, suggesting the use of a time‐consuming and inefficient view‐matching strategy for wayfinding. Individuals with WS also presented with deficits in allocentric spatial coding, demonstrated by difficulties in determining short‐cuts when required and difficulties developing a mental representation of the environment layout. This was found even following extensive experience in an environment, suggesting that – unlike in typical development – experience cannot contribute to the development of spatial relational processing in WS. This atypical presentation of both egocentric and allocentric spatial encoding is discussed in relation to specific difficulties on small‐scale spatial tasks and known atypical cortical development in WS. 相似文献

Marginal comments on student essays are a near‐universal method of providing feedback in philosophy. Widespread as the practice is, however, it has well‐known drawbacks. Commenting on students' work in the form of a video has the potential to improve the feedback experience for both instructors and students. The advantages of video feedback can be seen by examining it from both the professor's and the student's perspective. In discussing the professor's perspective, this article shares observations based on the author's experience delivering feedback through video. Turning to the student's view, it discusses qualitative feedback solicited from students that indicates a clear preference for video feedback over written marginalia. In particular, students describe video feedback as more informative, more personal, better at suggesting improvements on future assignments, enhancing the professor's ability to communicate through tone of voice and gesture, and easier to understand compared to written feedback. 相似文献

People prefer curved and symmetrical shapes to their angular and asymmetrical counterparts. While it is known that stimulus valence is central to approach and avoidance motivation, the exact nature of the relationship between curvature/symmetry and approach/avoidance motivation still needs to be clarified. Experiment 1 was designed to investigate whether simple shapes are associated with approach and avoidance words. Participants found it easier to match more symmetrical shapes with approach words. In Experiment 2, symmetry was differentially associated with approach words and was rated significantly higher on the approach dimension than asymmetry. Next, we assessed whether object valence and object curvature (Experiment 3) or symmetry (Experiment 4) would lead to different associations to approach and avoidance words. Only object valence had a significant influence on participants’ ratings, with the positively-valenced objects being more closely associated with approach words than their negatively-valenced counterparts. These results highlight the complex relation between visual properties of objects, their valence, and appetitive and aversive categories. 相似文献

Unconscious Thought Theory posits that a period of distraction after information acquisition leads to unconscious processing which enhances decision making relative to conscious deliberation or immediate choice (Dijksterhuis, 2004). Support thus far has been mixed. In the present study, artificial grammar learning was used in order to produce measurable amounts of conscious and unconscious knowledge. Intermediate phases were introduced between training and testing. Participants engaged in conscious deliberation of grammar rules, were distracted for the same period of time, or progressed immediately from training to testing. No differences in accuracy were found between intermediate phase groups acting on decisions made with meta-cognitive awareness (either feeling-based intuitive responding or conscious rule- or recollection-based responding). However, the accuracy of guess responses was significantly higher after distraction relative to immediate progression or conscious deliberation. The results suggest any beneficial effects of 'unconscious thought' may not always transfer to conscious awareness. 相似文献

Although risky decision-making has been posited to contribute to the maladaptive behavior of individuals with psychopathic tendencies, the performance of psychopathic groups on a common task of risky decision-making, the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994), has been equivocal. Different aspects of psychopathy (personality traits, antisocial deviance) and/or moderating variables may help to explain these inconsistent findings. In a sample of college students (N = 129, age 18–27), we examined the relationship between primary and secondary psychopathic features and IGT performance. A measure of impulsivity was included to investigate its potential as a moderator. In a joint model including main effects and interactions between primary psychopathy, secondary psychopathy and impulsivity, only secondary psychopathy was significantly related to risky IGT performance, and this effect was not moderated by the other variables. This finding supports the growing literature suggesting that secondary psychopathy is a better predictor of decision-making problems than the primary psychopathic personality traits of lack of empathy and remorselessness. 相似文献

We investigated whether a fearful expression enhances the effect of another's gaze in directing the attention of an observer. Participants viewed photographs of faces whose gaze was directed ahead, to the left or to the right. Target letters then appeared unpredictably to the left or right. As expected, targets in the location indicated by gaze were detected more rapidly. In nonanxious volunteers the effects of fearful gaze did not differ from neutral gaze, but fearful expression had a more powerful influence in a selected high anxious group. Attention is thus more likely to be guided by the direction of fearful than neutral gaze, but only in anxiety-prone individuals. 相似文献

The time course of different metacognitive experiences of knowledge was investigated using artificial grammar learning. Experiment 1 revealed that when participants are aware of the basis of their judgments (conscious structural knowledge) decisions are made most rapidly, followed by decisions made with conscious judgment but without conscious knowledge of underlying structure (unconscious structural knowledge), and guess responses (unconscious judgment knowledge) were made most slowly, even when controlling for differences in confidence and accuracy. In experiment 2, short response deadlines decreased the accuracy of unconscious but not conscious structural knowledge. Conversely, the deadline decreased the proportion of conscious structural knowledge in favour of guessing. Unconscious structural knowledge can be applied rapidly but becomes more reliable with additional metacognitive processing time whereas conscious structural knowledge is an all-or-nothing response that cannot always be applied rapidly. These dissociations corroborate quite separate theories of recognition (dual-process) and metacognition (higher order thought and cross-order integration). 相似文献

The latent construct of religiosity comprised measures of external, internal, and quest religiosity and was examined in relation to the latent construct of intolerant attitudes in a sample of undergraduate and graduate students at a Christian-affiliated university. The latent construct of intolerance included the indicators of rape and domestic violence myth acceptance, social dominance, dogmatism, and negative attitudes toward women. Multivariate results revealed significant negative correlations between internal and quest religiosity and indicators of intolerant attitudes, including the interpersonal violence myth acceptance scales. Quest religiosity also demonstrated unique univariate quadratic effects with both rape myth acceptance and domestic violence myth acceptance. Moderate levels of questing were associated with highest levels of interpersonal violence myth acceptance. Implications for the existing literature are discussed within the framework of a relational conceptualization of religiosity. 相似文献
