Humans appear to reason using two processing styles: System 1 processes that are quick, intuitive, and effortless and System 2 processes that are slow, analytical, and deliberate that occasionally correct the output of System 1. Four experiments suggest that System 2 processes are activated by metacognitive experiences of difficulty or disfluency during the process of reasoning. Incidental experiences of difficulty or disfluency--receiving information in a degraded font (Experiments 1 and 4), in difficult-to-read lettering (Experiment 2), or while furrowing one's brow (Experiment 3)--reduced the impact of heuristics and defaults in judgment (Experiments 1 and 3), reduced reliance on peripheral cues in persuasion (Experiment 2), and improved syllogistic reasoning (Experiment 4). Metacognitive experiences of difficulty or disfluency appear to serve as an alarm that activates analytic forms of reasoning that assess and sometimes correct the output of more intuitive forms of reasoning.  相似文献

Although several theories of online syntactic processing assume the parallel activation of multiple syntactic representations, evidence supporting simultaneous activation has been inconclusive. Here, the continuous and non-ballistic properties of computer mouse movements are exploited, by recording their streaming x, y coordinates to procure evidence regarding parallel versus serial processing. Participants heard structurally ambiguous sentences while viewing scenes with properties either supporting or not supporting the difficult modifier interpretation. The curvatures of the elicited trajectories revealed both an effect of visual context and graded competition between simultaneously active syntactic representations. The results are discussed in the context of 3 major groups of theories within the domain of sentence processing.  相似文献

Age-related memory deficits may result from attending to too much information (inhibition deficit) and/or storing too little information (binding deficit). The present study evaluated the inhibition and binding accounts by exploiting a situation in which deficits of inhibition should benefit relational memory binding. Older adults directed more viewing toward abrupt onsets in scenes compared with younger adults under instructions to ignore any such onsets, providing evidence for age-related inhibitory deficits, which were ameliorated with additional practice. Subsequently, objects that served as abrupt onsets underwent changes in their spatial relations. Despite successful inhibition of the onsets, eye movements of younger adults were attracted to manipulated objects. In contrast, the eye movements of older adults, who directed more viewing to the late onsets compared with younger adults, were not attracted toward manipulated regions. Similar differences between younger and older adults in viewing of manipulated regions were observed under free viewing conditions. These findings provide evidence for concurrent inhibition and binding deficits in older adults and demonstrate that age-related declines in inhibitory processing do not lead to enhanced relational memory for extraneous information.  相似文献

This study addressed the presence of executive dysfunction in children with CHARGE syndrome, a genetic disorder with multiple physical anomalies and severe challenging behaviors. Ninety-eight children were included in the study. More than half received clinically significant scores on the Behavior Rating Inventory of Executive Function (BRIEF; Gioia et al., 2000) scales of Shift, Monitor, and the Behavioral Regulation Index, with additional high scores on Inhibit and the Global Executive Composite. Associations were found with the age the child first walked, scores on the Autism Behavior Checklist (ABC; Krug et al., 1993), and being classified as deafblind. Difficulties with making transitions and flexible problem solving, monitoring their work and their effect on others, and acting on impulse, may be related to the behavioral difficulties exhibited by children with CHARGE. Interventions targeting improved self-regulation may help to manage this challenging behavior.  相似文献

Fears related to anxiety sensitivity (AS)-illness/injury sensitivity, fear of negative evaluation, and fear of pain-may have important theoretical associations with intolerance of uncertainty (IU). In separate investigations, AS and IU have been independently related to the same anxiety-related psychopathology. AS and IU seem to share a basis in fearing unknown, potentially harmful consequences; however, their inter-relationship remains uncertain. IU regarding a specific stimulus, a physical sensation for example, may result in a variety of interpretations and responses, including the catastrophic appraisals that characterize AS. The association between AS and IU was examined in a sample of 293 undergraduates. Results of confirmatory factor and correlation analyses suggest the two constructs are related, but nonetheless independent. It appears that IU may be a required component of catastrophic misappraisals while being an important construct related to fear and anxiety in its own right. Future research directions and potential applications are discussed.  相似文献

Suicide risk is thought to increase with a greater potential for activation of suicide-related schemas. Suicide schemas are less likely to be activated with reductions of emotional range associated with certain negative symptoms of schizophrenia. The study tested whether suicide risk would increase in patients with recent onset schizophrenia with increased potential for suicide schema activation as indicated by lower levels of specific negative symptoms that reflected emotional reactivity, namely emotional withdrawal and blunted affect. A logistic regression analysis of baseline data of 278 recent onset schizophrenic patients with a measure of suicide behaviour as the dependent variable and negative symptoms, delusions, hallucinations, depression, gender, episode, ethnicity, education, age, duration of untreated psychosis and substance use as independent variables was carried out. Emotional withdrawal, but not blunted affect was significant and negatively associated, and depression positively associated with suicide behaviour. There was evidence to indicate that restricted emotions are associated with reduced suicide risk as predicted.  相似文献

Past research shows that violent video game exposure increases aggressive thoughts, angry feelings, physiological arousal, aggressive behaviors, and decreases helpful behaviors. However, no research has experimentally examined violent video game effects on physiological desensitization, defined as showing less physiological arousal to violence in the real world after exposure to video game violence in the virtual world. This experiment attempts to fill this gap. Participants reported their media habits and then played one of eight violent or nonviolent video games for 20 min. Next, participants watched a 10-min videotape containing scenes of real-life violence while heart rate (HR) and galvanic skin response (GSR) were monitored. Participants who previously played a violent video game had lower HR and GSR while viewing filmed real violence, demonstrating a physiological desensitization to violence. Results are interpreted using an expanded version of the General Aggression Model. Links between desensitization, antisocial, and prosocial behavior are discussed.  相似文献

Ingroup advantages and outgroup deficits in perception and memory are well-established in research on race, gender, and other ostensibly identifiable social categories. The present study extended this research to a social category that is not as perceptually apparent: male sexual orientation. Consistent with hypotheses, an interaction of participant sexual orientation and image sexual orientation revealed an ingroup enhancement and outgroup deficit for memory of faces that participants perceived—both accurately and inaccurately—as belonging to either their ingroup or outgroup in a subsequent task. Additionally, parallel effects were found for the accurate identification of sexual orientation—a finding consistent with previous literature. The present data highlight the importance of social categorization for subsequent memory and suggest that the underlying cognitive machinery responsible for the recognition of groups may be co-opted for other relevant social applications.  相似文献
