Both human and non-human animals often face decisions between options available at different times, and the capacity of delaying gratification has usually been considered one of the features distinguishing humans from other animals. However, this characteristic can widely vary across individuals, species, and types of task and it is still unclear whether it is accounted for by phylogenetic relatedness, feeding ecology, social structure, or metabolic rate. To disentangle these hypotheses, we evaluated temporal preferences in capuchin monkeys, South-American primates that, despite splitting off from human lineage approximately 35 million years ago, show striking behavioural analogies with the great apes. Then, we compared capuchins’ performance with that of the other primate species tested so far with the same procedure. Overall, capuchins showed a delay tolerance significantly higher than closely related species, such as marmosets and tamarins, and comparable to that shown by great apes. Capuchins’ tool use abilities might explain their comparatively high preference for delayed options in inter-temporal choices. Moreover, as in humans, capuchin females showed a greater delay tolerance than males, possibly because of their less opportunistic foraging style. Thus, our results shed light on the evolutionary origins of self-control supporting explanations of delay tolerance in terms of feeding ecology.  相似文献

The coherent experience of the self and the world depends on the ability to integrate vs. segregate sensory information. Optimal temporal integration between the senses is mediated by oscillatory properties of neural activity. Previous research showed reduced temporal sensitivity to multisensory events in schizotypy, a personality trait linked to schizophrenia. Here we used the tactile-induced Double-Flash-Illusion (tDFI) to investigate the tactile-to-visual temporal sensitivity in schizotypy, as indexed by the temporal window of illusion (TWI) and its neural underpinnings. We measured EEG oscillations within the beta band, recently shown to correlate with the tDFI. We found individuals with higher schizotypal traits to have wider TWI and slower beta waves accounting for the temporal window within which they perceive the illusion. Our results indicate reduced tactile-to-visual temporal sensitivity to mediate the effect of slowed oscillatory beta activity on schizotypal personality traits. We conclude that slowed oscillatory patterns might constitute an early marker for psychosis proneness.  相似文献

The integration of spatial maps in pigeons was investigated using a spatial analog to sensory preconditioning. The pigeons were tested in an open-field arena in which they had to locate hidden food among a 4×4 grid of gravel-filled cups. In phase 1, the pigeons were exposed to a consistent spatial relationship (vector) between landmark L (a red L-shaped block of wood), landmark T (a blue T-shaped block of wood) and the hidden food goal. In phase 2, the pigeons were then exposed to landmark T with a different spatial vector to the hidden food goal. Following phase 2, pigeons were tested with trials on which they were presented with only landmark L to examine the potential integration of the phase 1 and 2 vectors via their shared common elements. When these test trials were preceded by phase 1 and phase 2 reminder trials, pigeons searched for the goal most often at a location consistent with their integration of the LT phase 1 and Tphase 2 goal vectors. This result indicates that integration of spatial vectors acquired during phases 1 and 2 allowed the pigeons to compute a novel Lgoal vector. This suggests that spatial maps may be enlarged by successively integrating additional spatial information through the linkage of common elements.  相似文献

Allies are members of an ingroup who work toward fairness for people in an outgroup. Ally behaviors include calling out discrimination and fighting for inclusion of outgroup members, and it includes public and private behaviors. As such, White allies can be an important means of reducing racism against people of color. There are few means of assessing and quantifying allyship in ingroup members, and as such, there is a need for methods for assessing allyship that can be used to better understand characteristics of allies and determine if interventions designed to reduce prejudice can improve allyship. To that end we describe an innovative scenario-based measurement technique to quantify interpersonal allyship, with White students as ingroup members (N = 987) and Black students as outgroup members (N = 61). Measurement of allyship is conducted based on participant responses to hypothetical racially-sensitive scenarios where microaggressions are occurring or likely to occur. Items were developed based focus group input, and rated by diversity experts for relevance. The factor structure of allyship items was examined by exploratory and confirmatory factor analyses. The final 10-item Interpersonal Racial Allyship Scale (IRAS) was negatively correlated to 3 measures of racist attitudes and 1 measure of microaggressive behaviors, and it was positively correlated to 2 measures of outgroup liking. It also predicted making racially supportive statements in a laboratory task. We report on characteristics of allies, noting that allied behaviors are correlated with less prejudice, stronger positive feelings toward outgroup members, and a greater likelihood of having other marginalized identities. Implications of findings and applications of the scale are discussed.  相似文献

This article emerges from the experience of incorporating doctoral students into our Contextual Education (CXE) Program at Emmanuel College (Toronto). This change, I argue, helped us to distinguish more clearly among and thus distinctly orient the different kinds of relationships and theological practices that make up our program towards the often‐elusive goal of curricular integration. After outlining a definition of integration, I contextualize that definition in our particular practices at Emmanuel College using Kathryn Tanner's (1997) understanding of theology as a cultural practice as my guide. I then offer a brief overview of our CXE Programs to demonstrate how nurturing strategic partnerships within them has made certain forms of integration possible for our students. I close with some activities for practical application in other CXE contexts.  相似文献

多感官线索整合的理论模型   总被引:4,自引:0,他引:4  
日常生活中,人脑能联合来自不同感官通道的线索对外部世界中的物体和事件进行感知。这些感官通道采用不同的参照系来表征物体的特征和位置;而且各种线索的可靠性也不恒定,根据环境而改变。但是人脑依然能够有效地整合这些线索,对物体和事件进行正确的感知。在以往研究的基础上,总结评述了多感官线索整合的几种理论模型及其验证结果,其中重点介绍了近年来引起广泛关注的贝叶斯统计优化模型。未来的研究应结合虚拟现实技术和脑成像技术对多感官线索整合进行探讨。  相似文献

Ecological validity of neuropsychological assessment includes the ability of tests to predict real-world functioning and/or covary with brain structures. Studies have examined the relationship between adaptive skills and test performance, with less focus on the association between regional brain volumes and neurobehavioral function in healthy children. The present study examined the relationship between temporal lobe gray matter volumes and performance on two neuropsychological tests hypothesized to measure temporal lobe functioning (visual perception-VP; peabody picture vocabulary test, third edition-PPVT-III) in 48 healthy children ages 5-18 years. After controlling for age and gender, left and right temporal and left occipital volumes were significant predictors of VP. Left and right frontal and temporal volumes were significant predictors of PPVT-III. Temporal volume emerged as the strongest lobar correlate with both tests. These results provide convergent and discriminant validity supporting VP as a measure of the "what" system; but suggest the PPVT-III as a complex measure of receptive vocabulary, potentially involving executive function demands.  相似文献

Binding aspects of an experience that are distributed over time is an important element of episodic memory. In the current study, we examined how the temporal complexity of an experience may govern the processes required for its retrieval. We recorded event-related potentials during episodic cued recall following pair associate learning of concurrently and sequentially presented object-picture pairs. Cued recall success effects over anterior and posterior areas were apparent in several time windows. In anterior locations, these recall success effects were similar for concurrently and sequentially encoded pairs. However, in posterior sites clustered over parietal scalp the effect was larger for the retrieval of sequentially encoded pairs. We suggest that anterior aspects of the mid-latency recall success effects may reflect working-with-memory operations or direct access recall processes, while more posterior aspects reflect recollective processes which are required for retrieval of episodes of greater temporal complexity.  相似文献

This article explores assignments as a core teaching practice essential to integrating the cognitive, personal, and professional identities of seminary students. These core practices emerge in seminary curricula where there is a strong focus on the teaching of canonical texts and a goal of achieving textual mastery. We propose that carefully chosen and constructive assignments achieve the kind of integration necessary for building content knowledge and the professional, spiritual, and religious identities of our students. While the difference between the educational goals of clergy‐training in a seminary and training graduate students in the academy can be sharp, we argue here for ways to make that contrast both productive and generative.  相似文献

In a recent issue of Consciousness and Cognition, Filbrich, Torta, Vanderclausen, Azanon, and Legrain (2016) commented on a paper in which we used a tactile Temporal Order Judgment (TOJ) task to show that expecting pain on a specific body location biased attention to that location (Vanden Bulcke, Crombez, Durnez, & Van Damme, 2015). Their main criticism is that the effects are likely to reflect response bias rather than genuine attentional bias. We agree that the TOJ task used may be susceptible to response bias, and welcome the authors’ methodological suggestions to control for such bias. However, we feel that certain aspects of our work are misrepresented in their paper. Most importantly, we contest their argument that our instructions made the threat location task-relevant, thereby increasing risk of response bias. Further, we reply to other methodological and theoretical issues raised by these authors.  相似文献

This article is an attempt to begin to weave together Freud's work - on dreams here envisioned as the original model for virtual reality - and from Fromm's work - on the impact of the market on personality. The contributions of these two psychoanalysts provide a necessary dual foundation for an understanding of emerging aspects of human psychology that are evolving, at the beginning of the 21st Century, alongside the profound influence of the electronically driven global market. It is time for psychoanalysis to engage more fully in the study of cultural forces. While it is easy to disregard dreams, both in the general culture and of late in psychoanalysis itself, dreams and their interpretation have always been central in human living, in the development of religion and in the birth of psychoanalysis as our own secular religion. Dreams, in their disembodiment and in their fluidity of information transformations have served as one model for developments within cyber culture and virtual living. The destruction of nature is seen as an underlying theme in the development of compatible relativist-subjectivist philosophies and in the growth of cyberculture. Thus, Freud's insights into dreams and Fromm's into the marketing personality are both crucial to an understanding of major contemporary forces.  相似文献

Participants made categorical or coordinate spatial judgments on the global or local elements of shapes. Stimuli were composed of a horizontal line and two dots. In the Categorical task, participants judged whether the line was above or below the dots. In the Coordinate task, they judged whether the line would fit between the dots. Stimuli were made hierarchical so that the global patterns composed of a “global line” made of local dots-and-line units, and “global dot” made of a single dots-and-line unit. The results indicated that the categorical task was better performed when participants attended to the local level of the hierarchical stimuli. On the other hand, the coordinate task was better performed when they attended to the global level. These findings are consistent with computer simulation models of the attentional modulation of neuronal receptive fields’ size suggesting that (1) coordinate spatial relations are more efficiently encoded when one attends to a relatively large region of space, whereas (2) categorical spatial relations are more efficiently encoded when one attends to a relatively small region of space.  相似文献

The unification of mind: Integration of hemispheric semantic processing   总被引:1,自引:0,他引:1  
Seventy-six participants performed a visual half-field lexical decision task at two different stimulus onset asynchronies (50 or 750 ms). Word targets were primed either by a highly associated word (e.g., CLEAN-DIRTY), a weakly associated word (e.g., CLEAN-TIDY), or an unrelated word (e.g., CLEAN-FAMILY) projected to either the same or opposite visual field (VF) as the target. In the short SOA, RVF-left hemisphere primes resulted in high associate priming regardless of target location (ipsilateral or contralateral to the prime) whereas LVF-right hemisphere primes produced both high and low associate priming across both target location conditions. In the long SOA condition, contralateral priming patterns converged, demonstrating only high associate priming in both VF locations. The results of this study demonstrate the critical role of interhemispheric transfer in semantic processing and indicate a need to elaborate current models of semantic processing.  相似文献

This paper describes an acculturative integration approach that stresses the contribution of liberation psychology. Immigrant integration is a challenge for receiving countries in the Western world due to the frequent asymmetrical and oppressive conditions suffered by newcomers in their new settlements. The cross-cultural perspective connects integration with psychological acculturation, emphasizing harmony between acquisitions of the new culture while maintaining cultural heritage, and creating opportunities for intergroup relationships. In turn, liberation psychology permits an understanding of the acculturative transition as an empowerment and self-construction process by which immigrants acquire a new vision of the world and of themselves, transforming both structural conditions and themselves. From this perspective we conceptualize acculturative integration as the process by which newcomers become an accepted part of the new society through a reflexive and evaluative process, changing their social references and position, rebuilding their social and personal resources, and achieving a new agency in coherence with their new challenges and goals. In this process, they acquire critical thinking about unequal conditions, gain capacities to respond to the inequalities, and take effective actions to confront them. We illustrate this process using the narratives of nine Moroccan women who are living in asymmetrical and oppressive local contexts in Andalusia, the southern-most region of Spain.  相似文献

Physical touch is central to the emotional intimacy that separates romantic relationships from other social contexts. In this study of 256 adults (128 heterosexual couples, mean relationship length?=?20.5 months), we examined whether individual differences in social anxiety influenced comfort with and avoidance of physical touch. Because of prior work on sex difference in touch use, touch comfort, and social anxiety symptoms and impairment, we explored sex-specific findings. We found evidence that women with greater social anxiety were less comfortable with touch and more avoidant of touch in same-sex friendships. Additionally, a woman’s social anxiety had a bigger effect on a man’s comfort with touch and avoidance of touch in the romantic relationship than a man’s social anxiety had on the woman’s endorsement of touch-related problems. These effects were uninfluenced by the length of romantic relationships. Touch is a neglected emotional experience that offers new insights into the difficulties of individuals suffering from social anxiety problems, and their romantic partners.  相似文献

A real-world open-field search task was implemented with humans as an analogue of Blaisdell and Cook’s (Anim Cogn 8:7–16, 2005) pigeon foraging task and Sturz, Bodily, and Katz’s (Anim Cogn 9:207–217, 2006) human virtual foraging task to 1) determine whether humans were capable of integrating independently learned spatial maps and 2) make explicit comparisons of mechanisms used by humans to navigate real and virtual environments. Participants searched for a hidden goal located in one of 16 bins arranged in a 4 × 4 grid. In Phase 1, the goal was hidden between two landmarks (blue T and red L). In Phase 2, the goal was hidden to the left and in front of a single landmark (blue T). Following training, goal-absent trials were conducted in which the red L from Phase 1 was presented alone. Bin choices during goal-absent trials assessed participants’ strategies: association (from Phase 1), generalization (from Phase 2), or integration (combination of Phase 1 and 2). Results were inconsistent with those obtained with pigeons but were consistent with those obtained with humans in a virtual environment. Specifically, during testing, participants did not integrate independently learned spatial maps but used a generalization strategy followed by a shift in search behavior away from the test landmark. These results were confirmed by a control condition in which a novel landmark was presented during testing. Results are consistent with the bulk of recent findings suggesting the use of alternative navigational strategies to cognitive mapping. Results also add to a growing body of literature suggesting that virtual environment approaches to the study of spatial learning and memory have external validity and that spatial mechanisms used by human participants in navigating virtual environments are similar to those used in navigating real-world environments.  相似文献
