ABSTRACT

The authors examine the idea, derived from Terror Management Theory, that concerns about undocumented immigrants stem from the need to protect death-buffering cultural values against the symbolic threat posed by dissimilar others. It is hypothesized that reminders of death will intensify aversion to culturally dissimilar immigrants. Forty-six university students were randomly assigned to a mortality salience or a control condition prior to evaluating either an illegal alien named Ben Johnson from Vancouver or Carlos Suarez from Mexico City. Consistent with the hypothesis, reactions to the Canadian target did not differ in the control and mortality salience conditions, whereas reactions to the Mexican immigrant were more negative in the mortality salience than in the control condition.  相似文献

Reappraisal is generally viewed as an adaptive emotion regulation strategy. Reappraisal frequency has been associated with greater well-being, and reappraisal ability is thought to be composed of several crucial cognitive control processes. However, the relationships among reappraisal ability, reappraisal frequency, well-being, and various cognitive control processes have not yet been determined. In this study, we experimentally examined individual differences in reappraisal ability (RA), and also assessed reappraisal frequency, well-being, and several cognitive control processes. We observed a positive relationship between RA, reappraisal frequency, and well-being. RA was also related positively to working memory capacity and set-shifting costs, and marginally related to abstract reasoning. These findings have important implications for understanding the cognitive components and affective outcomes of RA.  相似文献

Congruence is the degree to which one’s personality matches one’s behavior in a particular situation. On four separate occasions over several weeks, 202 undergraduate participants described a situation they encountered the previous day and their behavior. Analyses considered overall congruence as well as distinctive congruence, adjusted for the match of personality and behavior to the normative personality and behavior profile. Overall congruence was strongly associated with better psychological adjustment; distinctive congruence was not. Similarly, situation strength and affordances for autonomy, relatedness to others, and competence were strongly linked to overall congruence, but only weakly associated with distinctive congruence. Behaving in accordance with one’s true self is only related to positive psychological outcomes when it is accordance with normative standards.  相似文献

We report fMRI and behavioral data from 113 subjects on attention and cognitive control using a variant of the classic dichotic listening paradigm with pairwise presentations of consonant-vowel syllables. The syllable stimuli were presented in a block-design while subjects were in the MR scanner. The subjects were instructed to pay attention to and report either the left or right ear stimulus. The hypothesis was that paying attention to the left ear stimulus (FL condition) induces a cognitive conflict, requiring cognitive control processes, not seen when paying attention to the right ear stimulus (FR condition), due to the perceptual salience of the right ear stimulus in a dichotic situation. The FL condition resulted in distinct activations in the left inferior prefrontal gyrus and caudate nucleus, while the right inferior frontal gyrus and caudate were activated in both the FL and FR conditions, and in a non-instructed (NF) baseline condition.  相似文献

Mindfulness is a receptive attention to and awareness of events and experiences as they occur. A substantial body of literature supports the usefulness of mindfulness-based approaches for preventing or reducing emotional distress (e.g., depression and anxiety). However, mechanisms by which mindfulness produces these benefits are still being explored. Cognitive theories of emotional disorder implicate negatively biased cognition as a primary source of distress, and the theoretical literature on mindfulness suggests that it may reduce biased thoughts and judgments. Thus, the present research tested a mediation model in which less negatively biased cognition explains the inverse relation between mindfulness and emotional distress. Participants completed multiple standardized measures of trait mindfulness, negatively biased cognition, and emotional distress. The proposed relations between these constructs then were examined using structural equation modeling. Support was found for a partial mediation model, and possible alternative models were ruled out. These findings highlight a previously unidentified cognitive mechanism to explain the relation between mindfulness and reduced emotional distress. Specifically, mindfulness may reduce negative, maladaptive cognitive styles, which in turn may reduce predisposition to emotional disorders.  相似文献

Computational models are powerful tools – too powerful, according to some. We argue that the idea that models can “do anything” is wrong, and we describe how their failures have been informative. We present new work showing surprising diversity in the effects of feedback on children's task-switching, such that some children perseverate despite this feedback, other children switch as instructed, and yet others play an “opposites” game without truly switching to the newly instructed task. We present simulations that demonstrate the failure of an otherwise-successful neural network model to capture this failure. Simulating this pattern motivates the inclusion of updating mechanisms that make contact with a growing literature on frontostriatal function, despite their absence in theories of the development of cognitive flexibility. We argue from this and other examples that computational models are more constrained than is typically acknowledged and that their resulting failures can be theoretically illuminating.  相似文献

The Aymara of the Andes use absolute (cardinal) frames of reference for describing the relative position of ordinary objects. However, rather than encoding them in available absolute lexemes, they do it in lexemes that are intrinsic to the body: nayra (“front”) and qhipa (“back”), denoting east and west, respectively. Why? We use different but complementary ethnographic methods to investigate the nature of this encoding: (a) linguistic expressions and speech–gesture co‐production, (b) linguistic patterns in the distinct regional Spanish‐based variety Castellano Andino (CA), (c) metaphorical extensions of CA’s spatial patterns to temporal ones, and (d) layouts of traditional houses. Findings indicate that, following fundamental principles of Aymara cosmology, people, objects, and land—as a whole—are conceived as having an implicit canonical orientation facing east, a primary landmark determined by the sunrise. The above bodily based lexicalizations are thus linguistic manifestations of a broader macro‐cultural worldview and its psycho‐cognitive reality.  相似文献

Despite the accumulation of substantial cognitive science research relevant to education, there remains confusion and controversy in the application of research to educational practice. In support of a more systematic approach, we describe the Knowledge-Learning-Instruction (KLI) framework. KLI promotes the emergence of instructional principles of high potential for generality, while explicitly identifying constraints of and opportunities for detailed analysis of the knowledge students may acquire in courses. Drawing on research across domains of science, math, and language learning, we illustrate the analyses of knowledge, learning, and instructional events that the KLI framework affords. We present a set of three coordinated taxonomies of knowledge, learning, and instruction. For example, we identify three broad classes of learning events (LEs): (a) memory and fluency processes, (b) induction and refinement processes, and (c) understanding and sense-making processes, and we show how these can lead to different knowledge changes and constraints on optimal instructional choices.  相似文献

A reasoning strategy is iterative when the initial conclusion suggested by a set of premises is integrated into that set of premises in order to yield additional conclusions. Previous experimental studies on game theory-based strategic games (such as the beauty contest game) observed difficulty in reasoning iteratively, which has been partly attributed to bounded individual rationality. However, this difficulty has also been attributed to problems in adequately representing the beliefs, actions, and goals of other agents involved in the games. In four experiments, we observed similar difficulties in iterative reasoning in a variety of puzzles and games that did not involve social interactions with other agents, where they can only be caused by individual cognitive boundaries. Our findings are consistent with the hypothesis that an intrinsic difficulty in iterative reasoning originates from a tendency not to revise our initial mental representation of a problem in light of the initial conclusions that it implies.  相似文献
