The sensitivity of the Paced Auditory Serial Addition Task (PASAT) to working memory deficits may be enhanced by examining "dyads" (i.e., correct responses immediately preceded by a correct response) as a complement to the traditional total correct summary score. In a sample of 397 mostly African American (79%) healthy adults, total dyad and total correct scores were highly correlated (r = .96, p < .001); however, the magnitude of this association diminished in faster stimulus presentation trials, particularly among participants with impaired working memory abilities. 相似文献

A cognitive approach to game usability and design: mental model development in novice real-time strategy gamers. 总被引:1,自引:0,他引:1
We developed a technique to observe and characterize a novice real-time-strategy (RTS) player's mental model as it shifts with experience. We then tested this technique using an off-the-shelf RTS game, EA Games Generals. Norman defined mental models as, "an internal representation of a target system that provides predictive and explanatory power to the operator." In the case of RTS games, the operator is the player and the target system is expressed by the relationships within the game. We studied five novice participants in laboratory-controlled conditions playing a RTS game. They played Command and Conquer Generals for 2 h per day over the course of 5 days. A mental model analysis was generated using player dissimilarity-ratings of the game's artificial intelligence (AI) agents analyzed using multidimensional scaling (MDS) statistical methods. We hypothesized that novices would begin with an impoverished model based on the visible physical characteristics of the game system. As they gained experience and insight, their mental models would shift and accommodate the functional characteristics of the AI agents. We found that all five of the novice participants began with the predicted physical-based mental model. However, while their models did qualitatively shift with experience, they did not necessarily change to the predicted functional-based model. This research presents an opportunity for the design of games that are guided by shifts in a player's mental model as opposed to the typical progression through successive performance levels. 相似文献

When we forecast our futures, to what extent do we rely on explicit and concrete facts versus implicit and fleeting subjective experiences? Results from two studies reveal that forecasting judgments hinge on at least two fleeting experiences: the specific incidental emotions one happens to feel at the time of forming a judgment and the subjective ease-of-thought-generation. Results also reveal that imposing accountability for the accuracy of one's forecast provides no simple remedy. Incidental emotions, the ease-of-thought-generation, and accountability combine multiplicatively in a three-way interaction. Although accountability attenuates the respective effects of incidental fear and incidental anger, doing so has the undesirable effect of amplifying the ease-of-thought-generation effects that fear otherwise suppresses. In no instance does accountability completely eliminate the unintended effects of these fleeting subjective experiences. Discussion addresses implications for theories of affect and social cognition as well as for applications to risk perception. 相似文献

This paper studies consistency in the judged probability of a target hypothesis in lists of mutually exclusive nonexhaustive hypotheses. Specifically, it controls the role played by the support of displayed competing hypotheses and the relatedness between the target hypothesis and its alternatives. Three experiments are reported. In all experiments, groups of people were presented with a list of mutually exclusive nonexhaustive causes of a person's death. In the first two experiments, they were asked to judge the probability of each cause as that of the person's decease. In the third experiment, people were asked for a frequency estimation task. Target causes were presented in all lists. Several other alternative causes to the target ones differed across the lists. Findings show that the judged probability/frequency of a target cause changes as a function of the support of the displayed competing causes. Specifically, it is higher when its competing displayed causes have low rather than high support. Findings are consistent with the contrastive support hypothesis within the support theory. 相似文献

Two matched groups of mature painted turtles, Chrysemys picta picta, were trained in a simple runway, one with partial and the other with consistent reinforcement, following which both groups were extinguished. The partially reinforced animals ran more slowly in acquisition, but showed somewhat greater resistance to extinction. The results are compared with those obtained in analogous experiments with other animals. 相似文献

Socioeconomic position is often determined by uncontrollable, structural factors, yet people from the United States tend to attribute wealth and poverty to individual control. However, information about behavioural correlates of such beliefs across development is relatively lacking. Thus, we examined adolescents' reasoning about the causes of inequality in a sample of 599 adolescents from a socioeconomically, ethnically, and racially diverse middle school (grades 6–8). Additionally, early adolescents were presented with two novel groups with an unexplained wealth disparity and given a task in which they could perpetuate or rectify inequality. We found that while adolescents tended to give equitably and rectify the inequality, this outcome was predicted by the type of explanation they gave for societal inequality. Furthermore, participants' socioeconomic status and sexual identity predicted their inequality explanations. These results add to our knowledge of adolescent reasoning about inequality by demonstrating a potential link between attributions for inequality and giving behaviour. 相似文献

Nonparametric and distribution-free tests of categorical data provide an evaluation of statistical significance between groups of subjects differing in their assignment to a set of categories. This paper describes an implementation in the SAS programming language of three tests to evaluate categorical data. One of these tests, the Contingency Table Test for Ordered Categories evaluates data assessed on at least an ordinal scale where the categories are in ascending or descending rank order. The remaining two tests, Fisher’s Fourfold-Table Test for Variables with Two Categories and Fisher’s Contingency Table Test for Variables with More than Two Categories, evaluate data assessed on either a nominal or an ordinal scale. The program described completes analysis of a 2°C categorical contingency table as would be obtained from the application of a multiple-level rating scale to the behavior of a treatment and a control group. 相似文献

Computerized speech-recognition technology holds strong promise for psychological assessment. This paper focuses on a computerized speech recognition application for screening depressive symptomatology. A Macintosh-based prototype has been developed that uses the Center for Epidemiological Studies-Depression scale (CES-D). The prototype is a HyperCard stack interfaced with the Voice Navigator II speech recognition application. The “talking” program represents a viable depression screening tool that is fully voice operated by the respondent. A pilot study will assess the feasibility and acceptability of the computerized and written versions of the CES-D with a nonclinical adult population. A counterbalanced design will test for order effects and analyze the psychometric equivalence of the two methods. The limitations and future directions for speech-recognition applications in psychological assessment are discussed. 相似文献
