Relational reasoning is an essential component of fluid intelligence, and is known to have a protracted developmental trajectory. To date, little is known about the neural changes that underlie improvements in reasoning ability over development. In this event‐related functional magnetic resonance imaging (fMRI) study, children aged 8–12 and adults aged 18–25 performed a relational reasoning task adapted from Raven's Progressive Matrices. The task included three levels of relational reasoning demands: REL‐0, REL‐1, and REL‐2. Children exhibited disproportionately lower accuracy than adults on trials that required integration of two relations (REL‐2). Like adults, children engaged lateral prefrontal cortex (PFC) and parietal cortex during task performance; however, they exhibited different time courses and activation profiles, providing insight into their approach to the problems. As in prior studies, adults exhibited increased rostrolateral PFC (RLPFC) activation when relational integration was required (REL‐2 > REL‐1, REL‐0). Children also engaged RLPFC most strongly for REL‐2 problems at early stages of processing, but this differential activation relative to REL‐1 trials was not sustained throughout the trial. These results suggest that the children recruited RLPFC while processing relations, but failed to use it to integrate across two relations. Relational integration is critical for solving a variety of problems, and for appreciating analogies; the current findings suggest that developmental improvements in this function rely on changes in the profile of engagement of RLPFC, as well as dorsolateral PFC and parietal cortex. 相似文献

Most people believe that the future will bring them more good things than bad, and therefore have high hopes for the future
(MacLeod et al. Cogn Emot 10:69–85, 1996). However, many patients with mood disorders do not hold this positive belief about
the future. At the extreme, low expectations of positive outcomes in the future can lead to feelings of hopelessness (O’Connor
et al. Psychol Health Med 5:155–161, 2000). This paper aims to extend the literature on subjective probability of future events,
using a mood induction paradigm to examine the effects of transient mood change on perceived likelihood of future events in
a non-clinical community sample. Participants rated likelihood of future events from a standardized list and from their own
lives. Ratings were made in both normal and experimentally-induced positive or negative mood. Results show that self-generated
future events were perceived to be more likely than those from a standardized list, and that negative mood significantly biased
perceived likelihood of other-generated future events. Participants rating standardized list events saw positive outcomes
as less likely and negative outcomes as more likely in induced negative mood than they did in normal mood. Mood had no effect
on ratings of self-generated events. Possible directions for future research are discussed.

Encoding and dealing with conflicting information is essential for successful decision making in a complex environment. In
the present fMRI study, stimulus conflict and response conflict are contrasted in the context of a perceptual decision-making
dot-motion discrimination task. Stimulus conflict was manipulated by varying dot-motion coherence along task-relevant and
task-irrelevant dimensions. Response conflict was manipulated by varying whether or not competing stimulus dimensions provided
evidence for the same or different responses. The right inferior frontal gyrus was involved specifically in the resolution
of stimulus conflict, whereas the dorsal anterior cingulate cortex was shown to be sensitive to response conflict. Additionally,
two regions that have been linked to perceptual decision making with dot-motion stimuli in monkey physiology studies were
differentially engaged by stimulus conflict and response conflict. The middle temporal area, previously linked to processing
of motion, was strongly affected by the presence of stimulus conflict. On the other hand, the superior parietal lobe, previously
associated with accumulation of evidence for a response, was affected by the presence of response conflict. These results
shed light on the neural mechanisms that support decision making in the presence of conflict, a cognitive operation fundamental
to both basic survival and high-level cognition. 相似文献

Recently, the nature of children’s mental number line has received much investigation. In the number line task, children are required to mark a presented number on a physical number line with fixed endpoints. Typically, it was observed that the estimations of younger/inexperienced children were accounted for best by a logarithmic function, whereas those of older/more experienced children were reflected best by a linear function. This led to the conclusion that children’s mental number line transforms from logarithmic to linear with age and experience. In this study, we outline an alternative interpretation of children’s performance in a number line task. We suggest that two separate linear representations for one- and two-digit numbers may exist in young children and that initially the integration of these two representations into the place value structure of the Arabic number system is not fully mastered. When testing this assumption in a sample of more than 120 first graders, we observed that the two-linear model consistently provided better fit indexes. We conclude that instead of assuming a transition from logarithmic to linear coding, performance differences could also be accounted for by an improvement in integrating tens and units into the Arabic place value system. 相似文献

ABSTRACT The ontogeny of the ability to describe people culminates in adolescence in the development of the life story. An overarching temporal macrostructure and framing by a prehistory and a future-oriented global evaluation of life helps integrate disparate autobiographical memories into a coherent story. Two life narratives each of 8-, 12-, 16-, and 20-year-olds ( N =102) were analyzed in terms of how well-formed their beginnings and endings are and how much they follow a linear temporal order. By age 12, the majority of life narratives began with birth, ended in the present, and followed a chronological order. In late adolescence and early adulthood, more elaborate birth narratives and retrospective evaluations of life and outlooks into the future were added. These formal characteristics were related to biographical practices, biographical knowledge, and fluid intelligence. Text-analytical methods are proposed as a method for the analysis of biographical and autobiographical reasoning and understanding. 相似文献

Six studies investigated the relationship between production and comprehension by examining how relative clause production mechanisms influence the probabilistic information used by comprehenders to understand these structures. Two production experiments show that accessibility-based mechanisms that are influenced by noun animacy and verb type shape relative clause production. Two corpus studies confirm these production mechanisms in naturally occurring productions. Two comprehension studies found that nouns and verb types occurring in structures that speakers do not produce are difficult to comprehend. Specifically, the probability of producing a passive structure for a verb type in a given animacy configuration, as measured in the production and corpus studies, predicts comprehension difficulty in active structures. Results suggest that the way in which the verb roles are typically mapped onto syntactic arguments in production plays a role in comprehension. Implications for the relationship between production, comprehension and language learning are discussed. 相似文献

Prosocial video games reduce aggressive cognitions 总被引:2,自引:0,他引:2
Previous research has shown that playing violent video games increased aggressive tendencies. However, as pointed out by the General Learning Model (GLM) [Buckley, K. E., & Anderson, C. A. (2006). A theoretical model of the effects and consequences of playing video games. In: P. Vorderer & J. Bryant (Eds.), Playing video games motives responses and consequences (pp. 363-378). Mahwah, NJ: Lawrence Erlbaum], depending on their content, video games do not inevitably increase but may also decrease aggressive responses. Accordingly, the present research tested the hypothesis that playing prosocial video games decreases aggressive cognitions. In fact, playing a prosocial (relative to a neutral) video game reduced the hostile expectation bias (Experiment 1) and decreased the accessibility of antisocial thoughts (Experiment 2). Thus, these results lend credence to GLMs assumption that the effects of video game exposure depend to a great extent on the content of the game played. 相似文献

The purpose of this study was to evaluate the effects of a Spanish mental health video, “Cuida Su Salud Mental”, on the relationship attitudes and social skills knowledge of a Mexican immigrant sample. Subjects consisted of 72 Spanish speaking English as a second language (ESL) students recruited from the Paramount Adult School, in the county of Los Angeles. The Solomon (1949) Four Group Design was used. Half of the subjects were pretested on knowledge and attitudes about effective communication skills and relationships, respectively. All subjects view either the mental health video or a control video, and then were posttested on knowledge and attitudes. Results indicated that the mental healthy video (MHV) group exhibited more knowledge, F(1, 62) = 10.61, p= 0.002, and less risky attitudes, F(1, 62) = 4.29, p= 0.043, than the control video group. The MHV group also showed an increase in knowledge from the pretest to the posttest, F(1, 35) = 7.36, p= 0.01. Finally, both video groups reported a decrease in risky attitudes from pretest to posttest, F(1, 34) = 18.21, p= 0.001. These results support the use of “Cuida Su Salud Mental” as a productive and cost-effective mental health intervention that can be used to reach a large segment of the Spanish speaking community. 相似文献

Summary The subjective visual vertical (SV) has been investigated in centrifugation experiments in order to test the hypothesis, that changes in the SV are proportional to changes in the shear force acting on the utricles. The results deviate from those predicted from the shear hypothesis. This deviation can be accounted for by assuming that the SV is determined by the average of utricular and somaesthetic inputs.Thanks are due to A. Stein for performing some of the experiments of series d and e. N.J. Wade was supported by a Forschungsstipendium from the Alexander von Humboldt-Stiftung. Renate Alton skillfully assisted with the drawings. 相似文献
