Attention to Visual Feedback in Motor Learning

Visual guidance and movement to a stop were used to train subjects to make a simple movement without experiencing error in practice. Movement to a stop led to test performance as accurate as that after training with KR, but visual guidance did not. If a continuous visual cue as well as a stop were present during practice, subjects also performed less accurately, although they did not need to attend to the visual cue. All types of training were better than no training at all. Results are discussed in terms of the role of visual feedback in the development and assessment of programs for movement.     

Attention to Explicit and Implicit Contrast in Verb Learning

Contrast information could be useful for verb learning, but few studies have examined children's ability to use this type of information. Contrast may be useful when children are told explicitly that different verbs apply, or when they hear two different verbs in a single context. Three studies examine children's attention to different types of contrast as they learn new verbs. Study 1 shows that 3.5-year-olds can use both implicit contrast (“I'm meeking it. I'm koobing it.”) and explicit contrast (“I'm meeking it. I'm not meeking it.”) when learning a new verb, while a control group's responses did not differ from chance. Study 2 shows that even though children at this age who hear explicit contrast statements differ from a control group, they do not reliably extend a newly learned verb to events with new objects. In Study 3, children in three age groups were given both comparison and contrast information, not in blocks of trials as in past studies, but in a procedure that interleaved both cues. Results show that while 2.5-year-olds were unable to use these cues when asked to compare and contrast, by 3.5 years old, children are beginning to be able to process these cues and use them to influence their verb extensions, and by 4.5 years, children are proficient at integrating multiple cues when learning and extending new verbs. Together these studies examine children's use of contrast in verb learning, a potentially important source of information that has been rarely studied.     

The Touch Spots and the Intensity of the Stimulus

Most studies investigating the Stroop phenomenon have used duration of performance as a measure to demonstrate the interference effects. In the present study the Stroop phenomenon was examined by means of a recall test. Sixty male and female undergraduates, randomly assigned into one of three experimental conditions, were included in the study. The three conditions consisted of lists of six colored Xs, six colored words, and six color names printed in incongruent colors. The task was to recall the items in each list. Color names were recalled better than and at the expense of printed colors. These findings support the Norman and Bobrow notion regarding the limited amount of processing resources.     

Stimulus Control with Computer Assisted Learning

Computer Assisted Learning (CAL) has been shown to be an efficient learning-teaching procedure. Although there is an extensive educational software tradition using CAL approaches, few of them have demonstrated a better student performance than standard drill and practice methods. The purpose of this study was (a) to evaluate the effectiveness of the Let's Play With... software program, and (b) to evaluate the effectiveness of a prompt (i.e. a blinking object) used in the program. The educational software Let's Play With... was designed to teach basic concepts involving shapes and body positions to preschool students. The software structure follows a behavioral design and uses a stimulus control procedure. The study was carried out with 64 preschool students in the Cadiz (Spain) School District. Statistically significant differences were found between the experimental group and a control group.     

Intensity and the Sublime: Paying Attention to Self and Environment in Nature Sports

This paper responds to Kevin Krein’s claim in (2015) that the particular value of nature sports over traditional ones is that they offer intensity of sport experience in dynamic interaction between an athlete and natural features. He denies that this intensity is derived from competitive conflict of individuals and denies that nature sport derives its value from internal conflict within the athlete who carries out the activity. This paper responds directly to Krein by analysing ‘intensity’ in sport in terms of the relationship between attention and reflection and the interaction between self and environment. I reply directly to Krein’s rejection of self-competition as based on a mischaracterisation of internal struggle and argue that the weighing of incompatible desires does not involve a fragmented self. I argue that the unique intensity to which Krein refers is strongly comparable to the Kantian conception of the sublime and explore how sublime experience fits Krein’s account and outline some serious problems that such an ideal of experience poses for nature sport.

罗尔斯的公共理性理论及其与正义理论的关系

公共理性是罗尔斯在完善其正义理论的过程中提出的重要理念,但它并不是一个前后一致的理论,它只是在本初意图上是罗尔斯正义理论的组成部分,后来逐渐演变成具有相对独立性的理论形态。罗尔斯之所以将公共理性理论脱离原有的正义理论,在于其正义理论的失败。     

Selective Attention in Animal Discrimination Learning

The traditional approach to the study of selective attention in animal discrimination learning has been to ask if animals are capable of the central selective processing of stimuli, such that certain aspects of the discriminative stimuli are partially or wholly ignored while their relationships to each other, or other relevant stimuli, are processed. A notable characteristic of this research has been that procedures involve the acquisition of discriminations, and the issue of concern is whether learning is selectively determined by the stimulus dimension defined by the discriminative stimuli. Although there is support for this kind of selective attention, in many cases, simpler nonattentional accounts are sufficient to explain the results. An alternative approach involves procedures more similar to those used in human information-processing research. When selective attention is studied in humans, it generally involves the steady state performance of tasks for which there is limited time allowed for stimulus input and a relatively large amount of relevant information to be processed; thus, attention must be selective or divided. When this approach is applied to animals and alternative accounts have been ruled out, stronger evidence for selective or divided attention in animals has been found. Similar processes are thought to be involved when animals search more natural environments for targets. Finally, an attempt is made to distinguish these top-down attentional processes from more automatic preattentional processes that have been studied in humans and other animals.     

The Effect of Conditioned Stimulus Intensity upon a Simple Running Response

An experiment was designed to answer two questions regarding the correspondence between concrete and abstract actions. No significant differences were found, but because of deficiency of method, no conclusive answers could be given. The total scoring frequencies were in good accord with the results from the conditions 1 and 1* in the previous study [see earlier study for explanation of designations (2)], corroborating the evidence of that study regarding determinants of horizontal decalage.     

Exploring Spiritual Beliefs in Relation to Adlerian Theory

According to M. T. Burke et al. (1999), 1 key counselor competency regarding spirituality is the ability to explore one 's own religious and spiritual beliefs as a means to enhance sensitivity, understanding, and acceptance of such beliefs (as cited in G. Miller, 1999). In addition, an important part of professional development is said to involve ideological consistency between one's values and theoretical stance (T. M. Skovholt & M. H. Ronnestad, 1992). This article describes 1 counselor's exploration of her spiritual beliefs in relation to Adler's (H. L. Ansbacher & R. R. Ansbacher, 1956) theory of counseling and human development in an effort to move toward ideological consistency and to enhance competence in addressing spiritual dimensions of clients' development.     

Asymmetrical Perception of Changing Intensity in Short Tonal Stimuli: Duration of Stimulus

A number of reports have suggested that changing intensity in short tonal stimuli is asymmetrically perceived. In particular, steady stimuli may be heard as growing louder; stimuli must decrease in intensity to be heard as steady in loudness. The influence of stimulus duration on this perceptual asymmetry was examined. Three participants heard diotic tonal stimuli of eight durations between 0.8 s and 2.5 s. Each stimulus increased, decreased, or remained steady in intensity; initial intensity was 40 dB SPL (sound pressure level relative to 0.0002 dynes/cm²), and carrier frequency was 1 kHz. Participants made forced binary responses of “growing louder” or “growing softer” to each stimulus. For each duration, that value of intensity change eliciting equal numbers of both responses was determined. The results indicated a pronounced perceptual asymmetry for 0.8-s stimuli, which diminished for longer stimuli; changing intensity in 2.5-s stimuli was perceived symmetrically. Additionally, sensitivity to changing intensity improved as stimulus duration increased, suggesting that responses may be based in part on the difference in intensity between the beginning and end of the stimulus. Possible ramifications of the asymmetry reside in (a) the percussive nature of many natural sounds and (b) selective responding to approaching sound sources.     

内隐序列学习与注意的关系

内隐序列学习与注意的关系是内隐学习研究领域中的一个热点问题。“双注意机制”理论、“抑制表达”理论和“干扰外显学习成分”理论,从不同的角度阐释了内隐序列学习与注意的关系,但支持证据和反对意见并存,论争激烈。该文试图在一定程度上整合这三种理论,提出了“动态需求”假设,认为内隐序列学习任务对注意的需求是动态变化的,随着内隐序列学习任务中外显学习成分比重的变大,其对注意资源的需求也会随之增加     

On the Interaction of Prior Knowledge and Stimulus Structure in Category Learning

Contemporary theories of categorization propose that concepts are coherent in virtue of being embedded in a network of theories about the world. Those theories function to pick out some of the many possible features of a set of objects as most salient for purposes of classification, a process that is complex and still poorly understood (Murphy & Medin, 1985). Part of what makes this account incomplete is a lack of information as to (1) what makes a feature salient on a given occasion and (2) how feature salience interacts with category structure to determine the course of learning. We report on the results of three studies of category learning using complex schematic drawings to show that (1) the contrast set defined by one's initial encounters with category exemplars can be a source of individual differences in feature salience assignments; (2) such effects are short-lived in the face of clear evidence about actual feature diagnosticity; and (3) more robust prior hypotheses interact with category structure to either enhance learning or impede it. The enhancement occurs when the hypothesis emphasizes category-relevant features, even if the hypothesis is in fact incorrect. A hypothesis that assigns high salience to irrelevant features impedes learning. Learning does occur as feedback concerning category structure leads to enhanced salience for relevant features. Salience of irrelevant features remains high, however, suggesting that such learning as occurs involves augmentation and not total revision of the (incorrect) prior hypothesis.     

Using Reinforcement Learning to Examine Dynamic Attention Allocation During Reading

A fundamental question in reading research concerns whether attention is allocated strictly serially, supporting lexical processing of one word at a time, or in parallel, supporting concurrent lexical processing of two or more words (Reichle, Liversedge, Pollatsek, & Rayner, 2009). The origins of this debate are reviewed. We then report three simulations to address this question using artificial reading agents (Liu & Reichle, 2010; Reichle & Laurent, 2006) that learn to dynamically allocate attention to 1–4 words to “read” as efficiently as possible. These simulation results indicate that the agents strongly preferred serial word processing, although they occasionally attended to more than one word concurrently. The reason for this preference is discussed, along with implications for the debate about how humans allocate attention during reading.
