Beattie and Bradbury (1979) reported a study in which, in one condition, they punished speakers when they produced silent pauses (by lighting a light they were supposed to keep switched off). They found speakers were able to reduce silent pauses and that this was not achieved at the expense of reduced overall speech rate. They reported an unexpected increase in word repetition rate. A recent theory proposed by Howell, Au-Yeung, and Sackin (1999) predicts that the change in word repetition rate will occur on function, not content words. This hypothesis is tested and confirmed. The results are used to assess the theory and to consider practical applications of this conditioning procedure. 相似文献

以7~15岁儿童青少年为研究对象,考察加工速度和执行功能对流体智力的影响。研究结果表明,随着年龄的增长,感觉运动加工速度、知觉加工速度对流体智力从具有直接影响到只通过执行功能中的记忆更新成分产生间接影响,但这种影响存在年龄间的差异。在童年中期(7~9岁),知觉加工速度对流体智力不仅具有直接的预测作用,还通过记忆更新对其产生间接的影响。童年晚期(10~12岁),感觉运动加工速度和知觉加工速度不再对流体智力具有直接预测作用,都是通过记忆更新和抑制/转换合成成分间接对流体智力起作用。青春期(13~15岁),知觉加工速度对流体智力只通过记忆更新产生间接影响。 相似文献

Following a pretest, 8 participants who were unfamiliar with algebraic and trigonometric functions received a brief presentation on the rectangular coordinate system. Next, they participated in a computer-interactive matching-to-sample procedure that trained formula-to-formula and formula-to-graph relations. Then, they were exposed to 40 novel formula-to-graph tests and 10 novel graph-to-formula tests. Seven of the 8 participants showed substantial improvement in identifying formula-to-graph relations; however, in the test of novel graph-to-formula relations, participants tended to select equations in their factored form. Next, we manipulated contextual cues in the form of rules regarding mathematical preferences. First, we informed participants that standard forms of equations were preferred over factored forms. In a subsequent test of 10 additional novel graph-to-formula relations, participants shifted their selections to favor equations in their standard form. This preference reversed during 10 more tests when financial reward was made contingent on correct identification of formulas in factored form. Formula preferences and transformation of novel mathematical and stimulus functions are discussed. 相似文献

Is the Brain a Quantum Computer? 总被引:1,自引:0,他引:1
We argue that computation via quantum mechanical processes is irrelevant to explaining how brains produce thought, contrary to the ongoing speculations of many theorists. First, quantum effects do not have the temporal properties required for neural information processing. Second, there are substantial physical obstacles to any organic instantiation of quantum computation. Third, there is no psychological evidence that such mental phenomena as consciousness and mathematical thinking require explanation via quantum theory. We conclude that understanding brain function is unlikely to require quantum computation or similar mechanisms. 相似文献

Conditions under which children experience inhibitory difficulty with a "button-press" go/no-go task
Go/no-go tasks seem to provide a simple marker of inhibitory development in young children. Children are told to respond to one stimulus on go trials but to make no response to another stimulus on no-go trials; responding on no-go trials is assumed to reflect a failure to inhibit the go response. However, there is evidence to suggest that a type of go/no-go task, which we call the "button-press" task, does not require inhibition. We investigated the conditions under which young children (M=3 years 6 months, N=120) experience inhibitory difficulty with this type of task. The data suggest that the speed of stimulus presentation is crucial and that other studies using this type of task have presented the stimuli too briefly. The importance of establishing the inhibitory credentials of a task before it is used as a marker of inhibitory control is emphasized. 相似文献

A statistical manifold Mμ consists of positive functions f such that defines a probability measure. In order to define an atlas on the manifold, it is viewed as an affine space associated with a subspace of the Orlicz space LΦ. This leads to a functional equation whose solution, after imposing the linearity constrain in line with the vector space assumption, gives rise to a general form of mappings between the affine probability manifold and the vector (Orlicz) space. These results generalize the exponential statistical manifold and clarify some foundational issues in non-parametric information geometry. 相似文献

Abstract: The Jungian analysts who participated in the writing of this paper 1 explicitly or implicitly address issues of social and political stasis, retrogression and change via their particular usages of the concept of the transcendent function. Singer proposes that the transcendent function is a term that is usually applied to individuals in whom symbolic material appears that suggests the reconciling of opposites, leading to psycho‐spiritual growth. He also looks at the notion of the transcendent function as it can appear in a similar way in the collective psyche. In addition, he gives attention to the opposite phenomenon—what might be called the descendent function—as it appears in the collective psyche and its leadership, wherein symbolic material can create the division of groups of people into opposites, mobilizing destructive rather than transformative experience. Meador states that Jung designated the mediating process of assimilating unconscious images and ideas into consciousness as the transcendent function. Just as this synthesizing process can produce insight in the individual, it can also be applied to changes in collective society. Embedded collective assumptions tend to shift when opposites collide, as they did, for example, in the turmoils of the 1960s. Her contribution focuses on the recent revolution in racial and sexual attitudes as the product of a collective struggle between certain ingrained social mores from the past and conflicting new points of view. Samuels’ conclusion is that the concept of the transcendent function has little value with respect to political problems. His contribution focuses on: (i) The limitations of using ideas (such as the transcendent function) derived from analysis with individuals in furtherance of an understanding of social and political phenomena. (ii) The specific problem of a lack of credible psycho‐political models for social progress and regress—he argues that the transcendent function is not useful in this regard. (iii) The question of political aggression, violence and conflict in society is explored from the standpoint of the transcendent function so as to investigate its possible role in the management of political conflict. Samuels severely criticizes what he terms ‘triangulation’ and ‘hyper‐reflection’ on the part of analysts who engage with political debates and issues. (iv) Leadership is examined from the standpoint of the transcendent function which, again, does not seem pertinent. Rather, new discoveries in family psychology about the role of the father have greater possibilities as a basis for new thinking about leadership. 相似文献

Abstract: This paper describes the analysis of a patient whose difficulty symbolizing absence had prevented her from being able to mourn the loss of her father in her adolescence. Through a series of symbolic enactments and synchronistic events, she was eventually able to carry out a mourning ritual that enabled her to lay her father to rest. Some implications for symbolization are discussed, developing Segal's view of symbol formation as reparation: symbols are embedded in a context of communication and can only develop in the context of a relationship; they represent relationships as well as objects; and they are emergent in the sense that they exist within a complex web of interactive, multiple meaning and cannot be reduced back to any one object that they represent. 相似文献

Few studies have explored the effects of fixed‐time (FT) reinforcement on escape‐maintained behavior of students in a classroom setting. We measured the effects of an FT schedule on the disruptive and appropriate academic behaviors of 2 junior high students in a public school setting. Results demonstrated that FT escape from tasks resulted in a substantial decrease in disruptive behavior and an increase in time engaged in tasks for both participants. 相似文献
