Fixation on inappropriate concepts is a key barrier to problem solving. Previous research has shown that continuous work is likely to cause repeated retrieval of those concepts, resulting in increased fixation. Accordingly, distributing effort across problems through multiple, brief, and interlaced sessions (distributed effort) should prevent such fixation and in turn enhance problem solving. This study examined whether distributed effort can provide an advantage for problem solving, particularly for problems that can induce fixation (Experiment 1), and whether and how incubation can be combined with distributed effort to further enhance performance (Experiment 2). Remote Associates Test (RAT) problems were used as the problem-solving tasks. Half of them (i.e., misleading RAT) were more likely to mislead individuals to fixate on incorrect associates than the other half. Experiments revealed a superiority of distributed over massed effort on misleading RAT performance and a differing time course of incubation for the massed and distributed groups. We conclude that distributed effort facilitates problem solving, most likely via overcoming fixation. Cognitive mechanisms other than the commonly posited forgetting of inappropriate ideas may occur during incubation to facilitate problem solving. The experiments in this article offer support for the occurrence of spreading activation during incubation. 相似文献

Why do individuals mentally modify reality (e.g., “If it hadn’t rained, we would have won the game”)? According to the dominant view, counterfactuals primarily serve to prepare future performance. In fact, individuals who have just failed a task tend to modify the uncontrollable features of their attempt (e.g., “If the rules of the game were different, I would have won it”), generating counterfactuals that are unlikely to play any preparatory role. By contrast, they generate prefactuals that focus on the controllable features of their ensuing behavior (e.g., “If I concentrate more, I will win the next game”). Here, we test whether this tendency is robust and general. Studies 1a and 1b replicate this tendency and show that it occurs regardless of whether individuals think about their failures or their successes. Study 2 shows that individuals generate relatively few controllable counterfactuals, unless explicitly prompted to do so. These results raise some questions regarding the generality of the dominant view according to which counterfactuals mainly serve a preparatory function. 相似文献

Immigration is a global phenomenon, yet comparatively few psychological investigations of anti‐immigrant prejudice have been conducted in East Asia, a region of high economic growth that is set to become a leading destination for international migrants. Over two studies, we examined Singaporean attitudes towards four prominent immigrant groups: Chinese, Filipino, South Asian, and Western immigrants. Each immigrant group was found to be associated with a unique attitudinal profile. Chinese immigrants, who are culturally the most closely related to most Singaporeans, were viewed the most negatively in terms of prejudice, stereotyped warmth, and realistic and symbolic threat. Westerners were viewed the most positively despite higher ratings of perceived competence, possibly due to Western cultural influence, whereas South Asians and Filipinos were viewed as being relatively unthreatening, possibly due to their occupation of undesirable social roles. Perceived threat—both realistic and symbolic—proved to be stronger predictors of anti‐immigrant prejudice than stereotypes. Implications for immigration policy in the region are discussed. 相似文献

The aim of this paper is to motivate and then defend a restricted version of the truth-maker theory. In defending such a theory
I hope to do away with the perceived need for ‘negative existents’ such as totality facts and the like. 相似文献

Generalized structured component analysis (GSCA) is a component-based approach to structural equation modeling. In practice, researchers may often be interested in examining the interaction effects of latent variables. However, GSCA has been geared only for the specification and testing of the main effects of variables. Thus, an extension of GSCA is proposed to effectively deal with various types of interactions among latent variables. In the proposed method, a latent interaction is defined as a product of interacting latent variables. As a result, this method does not require the construction of additional indicators for latent interactions. Moreover, it can easily accommodate both exogenous and endogenous latent interactions. An alternating least-squares algorithm is developed to minimize a single optimization criterion for parameter estimation. A Monte Carlo simulation study is conducted to investigate the parameter recovery capability of the proposed method. An application is also presented to demonstrate the empirical usefulness of the proposed method. 相似文献

Although the outcomes of race categorization have been studied in detail, the temporal dynamics of real-time processing of race remain elusive. We measured participants’ hand movements en route to one of two race-category alternatives by recording the streaming x, y coordinates of the computer mouse. Study 1 showed that, when categorizing White and Black computer-generated faces that featurally overlapped with the opposite race, mouse trajectories showed a continuous spatial attraction toward the opposite category. Moreover, these race-atypical White and Black targets induced spatial attraction effects that had different temporal signatures. Study 2 showed that, when categorizing real faces that varied along a continuum of racial ambiguity, graded increases in ambiguity led to corresponding increases in trajectories’ attraction to the opposite category and trajectories’ movement complexity. These studies provide evidence for temporally dynamic competition across perceptions of race, where simultaneously and partially-active race categories continuously evolve into single categorical outcomes over time. Moreover, the findings show how different social category cues may exert different dynamic patterns of influence over the real-time processing that culminates in categorizations of others. 相似文献

The best defense of the doctrine of the Incarnation implies that traditional Christianity has a special stake in the knowability
paradox, a stake not shared by other theistic perspectives or by non-traditional accounts of the Incarnation. Perhaps, this
stake is not even shared by antirealism, the view most obviously threatened by the paradox. I argue for these points, concluding
that these results put traditional Christianity at a disadvantage compared to other viewpoints, and I close with some comments
about the extent of the burden incurred. 相似文献

To explore the mechanisms underlying the ability to intentionally forget, the present study combined an itemmethod directed
forgetting paradigm with tasks that measure stop-signal inhibition (Experiments 1 and 2) and inhibition of return (IOR; Experiment
2). Following each study-phase instruction to remember (R) or forget (F), a target was presented centrally (Experiment 1)
or to the left or right in the visual periphery (Experiment 2); the target required a speeded response that was sometimes
countermanded by a central stop signal. Although stopsignal reaction times were unaffected by the preceding memory instruction
(or relationship with word-target location), F instructions improved stopping and delayed responses. Replicating previous
findings in the literature, significant IOR was observed following F instructions but not following R instructions (Experiment
2). These findings suggest that intentional forgetting is an active cognitive process that more likely engages attentional
mechanisms related to orienting than those related to stop-signal inhibition. 相似文献

The preparatory attentional and memory processes theory of prospective memory (PM) assumes that PM retrieval requires resource-demanding
preparatory attentional processes, whereas the multiprocess theory assumes that retrieval can also occur spontaneously. On
the basis of showing slowing on an ongoing task (i.e., task interference) —even when the PM cue was highly salient (i.e.,
the participant’s own name) —Smith, Hunt, McVay, and McConnell (2007) concluded that preparatory attentional processes are
always necessary for PM retrieval. We argue that the presence of preparatory attentional processes cannot be used to rule
out the existence of spontaneous retrieval processes, and the goal of the present research was to examine whether PM retrieval
can occur in the absence of preparatory attentional processes. We varied whether we emphasized the importance of the PM task
or the ongoing task, and we assessed task interference across quarters of the ongoing task. Our results showed no evidence
of task interference and, hence, no evidence of preparatory attentional processes in the periods proximal to the target event,
and yet participants showed high PM performance. Thus, the results suggest the existence of spontaneous retrieval processes
and support the multiprocess theory. 相似文献

Many human and animal tasks are thought to be controlled with the tau informational variable. It is widely accepted that controlling the rate of change of tau (tau) during decelerative tasks, such as when braking or landing, is one common perceptual control strategy. However, many tasks require accelerating before decelerating to a goal, such as reaching. An advancement of tau theory shows how a single action formula may be used to control the full action unit from initiation to peak velocity, and to rest at the goal, with the same perceptual tau information as before and accounting for the same decelerative kinematics as before. Here, we test the theory against data from high-speed video of a hummingbird flying to its flower feeder. We find that the theory accounts for 97% of the variance in the data, and thus supports it. 相似文献
