The objective of this study is to quantify situational impacts on coping compared to the impact of personal characteristics. A facet design was used to systematically vary three situational features (ambiguity, social context, and concern at stake) in twenty vignettes of stressful situations that were presented to a sample of 430 healthy persons to elicit coping responses. In addition, relevant personal characteristics (mental health, self-esteem, perceived social support, and dispositional coping styles) were assessed. A series of variance component analyses demonstrated that for eight types of coping behavior, variability within individuals across situations was larger than variability between individuals. Multilevel analyses, accounting for both the person level and the situation level in the data, were employed to identify the situational features and personal characteristics that were responsible for situation-related variance and person-related variance respectively. Results demonstrate that all three situational features proved significant contributors to differentiated situation-specific coping patterns. No single personal factor could be identified as relevant in shaping coping behaviors, although the combined impact of personal factors explained a considerable amount of variance at the personal level. It is concluded that the study of situational features is a promising way to understand in which way situations shape coping behavior, and may be helpful in guiding the development of coping scales tailored to specific situations.  相似文献

How do human infants learn the causal dependencies between events? Evidence suggests that this remarkable feat can be achieved by observation of only a handful of examples. Many computational models have been produced to explain how infants perform causal inference without explicit teaching about statistics or the scientific method. Here, we propose a spiking neuronal network implementation that can be entrained to form a dynamical model of the temporal and causal relationships between events that it observes. The network uses spike‐time dependent plasticity, long‐term depression, and heterosynaptic competition rules to implement Rescorla–Wagner‐like learning. Transmission delays between neurons allow the network to learn a forward model of the temporal relationships between events. Within this framework, biologically realistic synaptic plasticity rules account for well‐known behavioral data regarding cognitive causal assumptions such as backwards blocking and screening‐off. These models can then be run as emulators for state inference. Furthermore, this mechanism is capable of copying synaptic connectivity patterns between neuronal networks by observing the spontaneous spike activity from the neuronal circuit that is to be copied, and it thereby provides a powerful method for transmission of circuit functionality between brain regions.  相似文献

ABSTRACT

This essay examines the role of public education in the process of place-remaking that relies on a false separation between teaching and issues of race, politics, and power. I construct a historical case study of my hometown that presents a counter narrative, presented by students, of race and legacy in the context of a public school and the surrounding community. Building upon a walk-as-method approach, I illustrate the confluence of historical, racialized narratives that are discoverable at the scale of the city but invisible within the walls of the school. I conclude with an in-progress professional code of ethical teaching and research practice for the learning sciences. These commitments are intended to support and protect students (and all young people in our communities) from bearing sole responsibility for critical stances based on their identities and histories-in-place.  相似文献

Our target article proposed a dual-system framework for understanding context and task effects in choice. In this summary, we address the major points made by each set of commentators and, building on their suggestions, define a more precise dual-system theory of preference construction. We also propose some avenues for future research on a broader dual-system approach to understanding choice.  相似文献

We manipulated two parameters of response blocking to reduce pica: (a) the criteria for initiating the procedure (either earlier or later in the response chain) and (b) the distance from which the procedure was initiated. Results suggested that response blocking may be effective only when implemented early in the chain and with near-perfect consistency. Further, additional treatment components may be required to eliminate all pica attempts.  相似文献

We examined how culture influences perceptions of applicant attributes when assessing employment suitability. In two studies (N = 408), we compared members from a collectivistic society (Singapore) to two samples from individualistic societies (the United States and Australia) on their perceptions of applicant attributes across job contexts. For each job, participants either chose between candidates with different attribute profiles or created ideal candidates by allocating a fixed amount of percentile points across different attributes. More often than Australians, Singaporeans chose the candidate with higher levels of the trait (e.g., openness to experience) uniquely associated with the job (e.g., graphic designer). More so than either Americans or Australians, Singaporeans prioritized having the trait most associated with each job. Members from collectivistic societies may require higher levels of the traits most associated with different jobs than members from individualistic societies, who prefer more well-rounded individuals for each job. As discussed, the study of lay perceptions may have implications for training hiring professionals and managers.  相似文献

ABSTRACT

Two experiments examined age differences in mechanisms hypothesized to affect activation of item and temporal information in working memory. Activation levels were inferred from the ability to reject n-back lures matching items in different temporal positions. Information with the least decay had a performance advantage over less recent information, but was susceptible to the same temporal context errors found in all adjacent-to-target lure positions. Lures most distant from the current item showed a performance rebound. The pattern of increased magnitudes of age effects at adjacent-to-target positions indicated a reduction in older adults' working memory for temporal context information above and beyond item memory declines. Results overall support the emphasis on context information as a critical factor in working memory and cognitive aging.  相似文献

Environmental context can have a profound influence on the efficacy of intervention protocols designed to eliminate undesirable behaviors. This is clearly seen in drug rehabilitation clinics where patients often relapse soon after leaving the context of the treatment facility. A similar pattern is commonly observed in controlled laboratory studies of context-dependent savings in instrumental conditioning, where simply placing an animal back into the original conditioning chamber can renew an extinguished instrumental response. Surprisingly, context-dependent savings in human procedural learning has not been carefully examined in the laboratory. Here, we provide the first known empirical demonstration of context-dependent savings in a perceptual categorization task known to recruit procedural learning. We also present a computational account of these savings using a biologically detailed model in which a key role is played by cholinergic interneurons in the striatum.  相似文献

The influence of test context on reports of recollection and familiarity depends on how these subjective recognition experiences are conceptualized and measured. Bodner and Lindsay (2003) found that critical items elicited more remember judgments but fewer know judgments in a less (vs. more) memorable context. In contrast, Tousignant and Bodner (2012) found that independent ratings of recollection and familiarity were both higher in a less memorable context. We replicated the dissociative pattern with judgments using recollect/familiar labels (Experiment 1), and in a novel R/F/B task that added a “both” option to eliminate the mutual exclusivity between the recollect and familiar options (Experiment 2). Adding a “guess” option eliminated these context effects (Experiment 3), however whether allowing guesses “cleans up” or “desensitizes” recollection and familiarity judgments remains unclear. Determining which task variants provide appropriate measures of subjective recognition experiences will require an examination of additional dissociations and triangulation with other measures.  相似文献
