The purpose of this study was to examine whether or not the feedback of the results of popular psychological tests influences human behavior, and to compare the strength of any influence with that of academic psychological tests. We conducted an experiment in which 64 female Japanese subjects took a popular or academic psychological test, and then interacted with a stranger. The subjects who took each test received bogus feedback implying that they were extroverted or introverted. The results showed that subjects who received the extroversion feedback were more interactive with a stranger than those who received the introversion feedback, irrespective of whether they had taken the popular or academic test. This suggests that the feedback of popular psychological tests, like that of academic tests, can influence human behavior and create a self-fulfilling prophecy. The results also showed that those subjects who took the popular psychological tests reported higher psychological well-being than those who took the academic tests. 相似文献

It is very important to choose appropriate variables to be analyzed in multivariate analysis when there are many observed variables such as those in a questionnaire. What is actually done in scale construction with factor analysis is nothing but variable selection.In this paper, we take several goodness-of-fit statistics as measures of variable selection and develop backward elimination and forward selection procedures in exploratory factor analysis. Once factor analysis is done for a certain numberp of observed variables (thep-variable model is labeled the current model), simple formulas for predicted fit measures such as chi-square, GFI, CFI, IFI and RMSEA, developed in the field of the structural equation modeling, are provided for all models obtained by adding an external variable (so that the number of variables isp + 1) and for those by deleting an internal variable (so that the number isp – 1), provided that the number of factors is held constant.A programSEFA (Stepwise variable selection in Exploratory Factor Analysis) is developed to actually obtain a list of the fit measures for all such models. The list is very useful in determining which variable should be dropped from the current model to improve the fit of the current model. It is also useful in finding a suitable variable that may be added to the current model. A model with more appropriate variables makes more stable inference in general.The criteria traditionally often used for variable selection is magnitude of communalities. This criteria gives a different choice of variables and does not improve fit of the model in most cases.The URL of the programSEFA is http://koko15.hus.osaka-u.ac.jp/~harada/factor/stepwise/. 相似文献

The pervasive use of distributional semantic models or word embeddings for both cognitive modeling and practical application is because of their remarkable ability to represent the meanings of words. However, relatively little effort has been made to explore what types of information are encoded in distributional word vectors. Knowing the internal knowledge embedded in word vectors is important for cognitive modeling using distributional semantic models. Therefore, in this paper, we attempt to identify the knowledge encoded in word vectors by conducting a computational experiment using Binder et al.'s (2016) featural conceptual representations based on neurobiologically motivated attributes. In an experiment, these conceptual vectors are predicted from text-based word vectors using a neural network and linear transformation, and prediction performance is compared among various types of information. The analysis demonstrates that abstract information is generally predicted more accurately by word vectors than perceptual and spatiotemporal information, and specifically, the prediction accuracy of cognitive and social information is higher. Emotional information is also found to be successfully predicted for abstract words. These results indicate that language can be a major source of knowledge about abstract attributes, and they support the recent view that emphasizes the importance of language for abstract concepts. Furthermore, we show that word vectors can capture some types of perceptual and spatiotemporal information about concrete concepts and some relevant word categories. This suggests that language statistics can encode more perceptual knowledge than often expected. 相似文献

In the present study, the extent to which the early component of somatosensory evoked potentials (SEPs) and the Hoffmann (H-) reflex induced by stimulation of the posterior tibial nerve are altered during the ascending and descending phases of fast plantarflexion was investigated. SEPSs and H-reflex of the soleus following tibial nerve stimulation were examined during fast plantarfiexion when performed by nine normal subjects. The analyses focused on differences in amplitude modulation of the P30-P40 component of SEP and the H-reflex between the ascending and descending phases of full-wave rectified and averaged soleus electromyographic (EMG) activity. The H-reflex amplitude was significantly increased and decreased during the ascending and descending phases more than under resting control conditions, respectively. The reduction of SEP amplitude was 49% for the ascending phase and 83% for the descending phases with respect to the resting situation. Modulation of SEP during the ascending and descending phases was robustly retained even during ischemic nerve blockade of large diameter afferent fibers. These findings suggest that the transmission of afferent inputs from muscle spindles to motoneurons and to the somatosensory cortex during fast isometric contraction of the plantar flexor is regulated in a time-dependent fashion by descending commands. 相似文献

The present study investigated use of life review, a form of reminiscence, on the depression and self-esteem in cancer patients. 15 cancer patients in the experimental group participated in individual reminiscence therapy. 21 patients in the comparison group received no therapy. All patients were measured on both depression and self-esteem scales during two testing periods. Analysis showed mean depression scores of the cancer patients decreased and mean self-esteem increased significandy after the life-review therapy sessions, while the scores of the comparison group did not change. Furthermore, patients' psychological states were improved, and they thought their problems had been addressed. These results suggest reminiscence therapy can be useful for cancer patients. 相似文献

The ability of four tufted capuchin monkeys (Cebus apella) to recognize the causal connection between seeing and knowing was investigated. The subjects were trained to follow a suggestion
about the location of hidden food provided by a trainer who knew where the food was (the knower) in preference to a trainer
who did not (the guesser). The experimenter baited one of three opaque containers behind a cardboard screen so that the subjects
could not see which of the containers hid the reward. In experiment 1, the knower appeared first in front of the apparatus
and looked into each container; next, the guesser appeared but did not look into any containers. Then the knower touched the
correct cup while the guesser touched one of the three randomly. The capuchin monkeys gradually learned to reach toward the
cup that the knower suggested. In experiment 2, the subjects adapted to a novel variant of the task, in which the guesser
touched but did not look into any of the containers. In experiment 3, the monkeys adapted again when the knower and the guesser
appeared in a random order. These results suggest that capuchin monkeys can learn to recognize the relationship between seeing
and knowing.

The monoamine theory has implicated abnormalities in serotonin and norepinephrine in the pathophysiology of major depression and bipolar illness and contributed greatly to our understanding of mood disorders and their treatment. Nevertheless, some limitations of this model still exist that require researchers and clinicians to seek further explanation and develop novel interventions that reach beyond the confines of the monoaminergic systems. Recent studies have provided strong evidence that glutamate and other amino acid neurotransmitters are involved in the pathophysiology and treatment of mood disorders. Studies employing in vivo magnetic resonance spectroscopy have revealed altered cortical glutamate levels in depressed subjects. Consistent with a model of excessive glutamate-induced excitation in mood disorders, several antiglutamatergic agents, such as riluzole and lamotrigine, have demonstrated potential antidepressant efficacy. Glial cell abnormalities commonly associated with mood disorders may at least partly account for the impairment in glutamate action since glial cells play a primary role in synaptic glutamate removal. A hypothetical model of altered glutamatergic function in mood disorders is proposed in conjunction with potential antidepressant mechanisms of antiglutamatergic agents. Further studies elucidating the role of the glutamatergic system in the pathophysiology of mood and anxiety disorders and studies exploring the efficacy and mechanism of action of antiglutamatergic agents in these disorders, are likely to provide new targets for the development of novel antidepressant agents. 相似文献

Differences between North American and East Asian cultures were examined in terms of the valence of psychological constructs. Americans were more likely than Japanese to focus on positive things. In contrast, Japanese ( vs Americans) were more likely to attend to negative information of the self, but not more or less likely to focus on negative things about others. Based on within-culture analyses, the Americans' data were better described by their tendency to focus on positive things over negative things than by their tendency for self-enhancement. In contrast, the Japanese data were better described by their self-critical tendency. This result was replicated in a second study. In addition, correlations between constructs with opposite valences were negative in the USA, but positive or absent in Japan. 相似文献

In parent–child interaction therapy (PCIT), therapists encourage parents to imitate child behaviors in order to convey approval of the child’s actions and promote the development of linguistic and social–cognitive skills. However, the Dyadic Parent-Child Interaction Coding System (DPICS-IV), used to measure skills taught during PCIT, does not include guidelines for coding parent–child imitation, making it difficult to determine how PCIT affects it. The current study addresses this problem by developing guidelines for coding imitation, which were then used to code DPICS-IV segments from 58 Mexican American families that participated in a past clinical trial. Results suggest that these coding guidelines can be used to reliably measure parent and child imitation. A series of additional analyses supported the construct validity of the codes. Specifically, there was a trend for parent imitation, but not child imitation, to increase more from pre–post treatment in PCIT relative to treatment as usual. In addition, parents who imitate their children were found to have children who imitate them more in return. Finally, improvement in parent imitation, but not child imitation, was significantly related to a decrease in child behavior problems. Further study is needed to determine the optimal frequency of imitation, and findings suggest that additional attention to coaching imitation may be warranted. 相似文献
