汉语“主观词”的表征及其加工

本文提出了"主观词"的概念,并探讨主观词存在的心理现实性以及主观词的加工特征。包括3项研究:研究1考察了普通大学生对双字结构的词汇辨别情况,发现他们倾向于将短语和词主观判断为词,即他们按照个体对词的独特表征认知词,证实了主观词存在的心理现实性。研究2和研究3分别采用"词优效应"研究中使用的强迫选择作业和词汇判断任务考察主观词加工的特征。研究2发现,读者加工词和主观词(语法上是短语但主观评定为词)的正确率和反应时没有差异,但与非词条件相比,表现为正确率高,反应时短;研究3的反应时结果同研究2,而3种条件的正确率均在90%以上且不存在显著差异。在本研究条件下,得出以下结论:(1)主观词的存在具有心理现实性:读者对汉语词语的表征是主观的,不一定符合词的语法学规定;(2)在强迫选择作业下,与非词相比,表现出词优效应,主观词作为整体被识别。(3)在词汇判断任务下,主观词与词相同,与非词相比,表现出加工优势。

Halving and doubling isometric force: Evidence for a decelerating psychophysical function consistent with an equilibrium-point model of motor control

Several previous investigations have measured accelerating psychophysical functions for perceived force with exponents of about 1.7. Two halving and doubling experiments presented here imply a psychophysical function for perceived force with an exponent between 0.6 and 0.8. That is, more than a doubling of force was needed to double the sensation, and similarly for halving. In the first experiment, subjects squeezed rigid instrumented cylinders between the thumb and first two fingers of each hand. They generated and released a reference force with one hand, and then squeezed the opposite hand to produce a sensation magnitude equal to, twice that, or half that of the reference. An analysis using a model that accounted for compression bias yielded average psychophysical functions with exponents of 0.58 and 0.59 (nondominant and dominant hands, respectively). The second experiment was an attempt to replicate earlier results and to reconcile them with the first experiment by using a paradigm duplicated from a previous study. Subjects in the second experiment made unilateral halving and doubling judgments of handgrip while squeezing a hand dynamometer. Again, the halving and doubling judgments yielded decelerating functions with exponents of 0.75 and 0.80 (nondominant and dominant hands, respectively). Even though the results of the first two experiments contradict earlier investigations, they can be explained by an equilibrium model of motor control assuming that subjects halve and double the central motor command rather than the sensation of force. The force is simply the result of the mechanical equilibrium established between the load and the compliant effector (the hand). The predicted relationship between the motor command judgments, the compliance of the hand, and the resultant forces was confirmed in a third experiment in which the mechanical compliance of the three-finger pinch was measured by using a pneumatic manipulandum to apply force perturbations in a “do-notintervene” paradigm. The measured compliance characteristic was accelerating, just as predicted by the model, in order to produce a decelerating psychophysical function for “perceived force.” In this experiment, then, judgments of perceived force appear to be judgments of the central motor command.     

Differences in spatial knowledge acquired from maps and navigation

Models of the spatial knowledge people acquire from maps and navigation and the procedures required for spatial judgments using this knowledge are proposed. From a map, people acquire survey knowledge encoding global spatial relations. This knowledge resides in memory in images that can be scanned and measured like a physical map. From navigation, people acquire procedural knowledge of the routes connecting diverse locations. People combine mental simulation of travel through the environment and informal algebra to compute spatial judgments. An experiment in which subjects learned an environment from navigation or from a map evaluates predictions of these models. With moderate exposure, map learning is superior for judgments of relative location and straight-line distances among objects. Learning from navigation is superior for orienting oneself with respect to unseen objects and estimating route distances. With extensive exposure, the performance superiority of maps over navigation vanishes. These and other results are consonant with the proposed mechanisms.     

On the Affine Structure of Perceptual Space

Affine geometry is a generalization of Euclidean geometry in which distance can be scaled along parallel directions, though relative distances in different directions may be incommensurable. This article presents a new procedure for testing the intrinsic affine structure of a psychological space by having subjects perform bisection judgments over multiple directions. If those judgments are internally consistent with one another, they must satisfy a theorem first proved by Pierre Varignon around 300 years ago. In the experiment reported here, this procedure was employed to measure the perceived structure of a visual ground surface. The results revealed that observers' judgments were systematically distorted relative to the physical environment, but that the judged bisections in different directions had an internally consistent affine structure. Implications of these findings for other possible response tasks are considered.     

The Influence of Self-Ratings versus Peer Ratings on Supervisors'' Performance Judgments

This study investigated the extent to which supervisors use feedback from outside sources in making performance judgments. A simulation was conducted in which participants with organizational supervisory experience made an initial performance judgment about a profiled employee. Participants then received additional information that was discrepant from their initial judgment (positive or negative) from one of two sources (the profiled employee himself or one of his peers). The direction of the discrepant information and its source interacted in determining final ratings, such that, participants were more likely to use discrepant information to alter their performance judgments in a consistent direction when the source was a peer than when the source was the employee himself. Furthermore, participants' opinions about the usefulness of peer information for performance judgments moderated this interaction. Specifically, participants who believed that information from an employee's peers was useful, were more likely to use discrepant information provided by a peer when making final performance judgments than were participants who did not believe that information from an employee's peers was useful.     

The lifespan of time intervals in reference memory

To further explore how memory influences time judgments, we conducted two experiments on the lifespan of temporal representations in memory. Penney et al (2000, Journal of Experimental Psychology Human Perception and Performance 26 1770-1787) reported that the perceived duration of auditorily and visually marked intervals differs only when both marker-type intervals are compared directly. This finding can be explained by a 'memory-mixing' process, whereby the memory trace of previous intervals influences the perception of upcoming ones, which are then added to the memory content. In the experiments discussed here, we manipulated the mixing mode of auditory/visual signal presentations. In experiment 1, signals from the same modality were either grouped by blocks or randomised within blocks. The results showed that the auditory/visual difference decreased but remained present when modalities were grouped by blocks. In experiment 2, we used a line-segmentation task. The results showed that, after a training block was performed in one modality, the perceived duration of signals from the other modality was distorted for at least 30 trials and that the magnitude of the difference decreased as the block went on. The results of both experiments highlight the influence of memory on time judgments, providing empirical support to, and quantitative portrayal of, the memory-mixing process.     

An eye movement analysis of "mental rotation" of simple scenes

Participants saw a standard scene of three objects on a desktop and then judged whether a comparison scene was either the same, except for the viewpoint of the scene, or different, when one or more of the objects either exchanged places or were rotated around their center. As in Nakatani, Pollatsek, and Johnson (2002), judgment times were longer when the rotation angles of the comparison scene increased, and the size of the rotation effect varied for different axes and was larger for same judgments than for different judgments. A second experiment, which included trials without the desktop, indicated that removing the desktop frame of reference mainly affected the y-axis rotation conditions (the axis going vertically through the desktop plane). In addition, eye movement analyses indicated that the process was far more than a simple analogue rotation of the standard scene. The total response latency was divided into three components: the initial eye movement latency, the first-pass time, and the second-pass time. The only indication of a rotation effect in the time to execute the first two components was for z-axis (plane of sight) rotations. Thus, for x- and y-axis rotations, rotation effects occurred only in the probability of there being a second pass and the time to execute it. The data are inconsistent either with an initial rotation of the memory representation of the standard scene to the orientation of the comparison scene or with a holistic alignment of the comparison scene prior to comparing it with the memory representation of the standard scene. Indeed, the eye movement analysis suggests that little of the increased response time for rotated comparison scenes is due to something like a time-consuming analogue process but is, instead, due to more comparisons on individual objects being made (possibly more double checking).     

Intuitive Judgments of Rate Change: The Case of Teenage Pregnancies

Three studies examined intuitive judgments of rate change. These studies considered how people intuitively decide that the occurrence rate of particular events is on the increase or in decline. Using the topic of teenage pregnancy, participants were given information about the population size and the frequency of pregnancies at a hypothetical high school in three studies at two points in time. In the first of these studies details about population size were made highly salient, and here population information was found to directly influence intuitive judgments of rate change. In the second study population information was presented in a more realistic fashion. Under these conditions judgments that the pregnancy rate had changed were found to be based on changes in the number of pregnancies. Whenever the number of pregnancies changed, regardless of compensating changes in school size, people inferred a change in rate. In the third of these studies, population details were not provided; only information about number of pregnancies was presented. Subjects' queries for additional information were then assessed. Despite the absence of population information, few subjects requested population details when asked what additional information they would like in order to judge the relative seriousness of the pregnancy problem. Taken together, the three studies suggest that when making intuitive judgments of change in rate, people may be relatively insensitive to the importance of population information. The implications of such findings are discussed.     

Depth matching with visible diplopic images: Stereopsis or vernier alignment

In order to prevent subjects from actually performing a judgment of vernier alignment between the double images rather than matching stereoscopic depth of the test objects, various precautions have previously been taken, e.g., using inexperienced subjects who were ignorant of the experimental situation and possible matching criteria. In the experiment reported here, a subject was given training in observing double images and the matching problems were also discussed. The subject was then instructed to perform stereoscopic depth judgments. The comparison between these data and data based on vernier alignment judgments under similar conditions showed that knowledge about the experimental situation and the vernier alignment criterion did not interfere with the subject’s task of matching the stereoscopic depth between visible double images.     

Acquisition functions in contingency judgment

Two experiments investigated the way in which judgments of the extent to which an action caused an outcome changed as more experience of the actionoutcome contingency was presented. In the first experiment judgments increased across trials when there was a positive contingency and decreased when there was a negative contingency. In noncontingent situations judgments were biased by the overall probability of the outcome. In the second experiment the changes across trials under positive and negative contingencies persisted even when the subjects were given the opportunity to dissociate their causality judgments from their degree of confidence in those judgments. The results are at variance with the dP and dD theories which attempt to account for causality judgments in terms of statistical rules based on the probabilities or frequencies of the relevant events. If such theories were modified, however, to take account of the regression of the subjects' estimates onto the actual probabilities or frequencies, then the data could be accommodated. On the other hand, a simple associative view is also able to account for the data.     

Maximum likelihood estimation in multidimensional scaling

A variety of distributional assumptions for dissimilarity judgments are considered, with the lognormal distribution being favored for most situations. An implicit equation is discussed for the maximum likelihood estimation of the configuration with or without individual weighting of dimensions. A technique for solving this equation is described and a number of examples offered to indicate its performance in practice. The estimation of a power transformation of dissimilarity is also considered. A number of likelihood ratio hypothesis tests are discussed and a small Monte Carlo experiment described to illustrate the behavior of the test of dimensionality in small samples.The research reported here was supported by grant number APA 320 to the author by the National Research Council of Canada.
