Different groups of goldfish were trained to discriminate between a circle and either a square, a diamond, a square with a knob added at the top or a diamond with a knob. All subjects readily mastered the discrimination, and there was no significant difference between the groups in the number of trials taken to criterion. In transfer tests it was found that: (i) while there was no transfer from square to diamond or vice versa, the presence of knobs on these shapes did mediate transfer from one to the other, provided the knob remained in the top part of the shapes; (ii) all groups learned much more about the tops of the shapes than about the bottom halves; (iii) animals discriminated the square from the circle largely by detecting the presence of a strong horizontal edge at the top of the figure; (iv) two features of the diamond were discriminated--the presence of oblique contours and the existence of a point in the upper half of the shape. The results are discussed in terms of a proposed model of shape recognition. 相似文献

Mechanical restraints are commonly used to reduce the risks associated with severe self-injurious behavior (SIB), but may result in movement restriction and adverse side effects (e.g., bone demineralization). Restraint fading may provide a method for decreasing SIB while increasing movement and reducing these side effects. In the current investigation, rigid arm sleeves and restraint fading (gradually reducing the rigidity of the sleeves) were used with 3 clients who engaged in hand-to-head SIB. Restraints and fading reduced the hand-to-head SIB of all clients. However, for 1 client, the addition of a water mist procedure further reduced SIB to near-zero levels. For a 2nd client, another form of SIB developed that was not prevented by the rigid sleeves. For a 3rd client, a topography of SIB that was not physically prevented by the rigid sleeves was also reduced when restraints and fading were introduced. 相似文献

This article examines some of the assumptions underlying cultural evolution and such concepts as the Noble Savage and the Golden Age. Looking briefly at the influence and inference of these ideas in the past, their use and appearance in certain aspects of contemporary Pagan and New Age thought are then explored. The notion of the Noble Savage has recurred in various guises since at least classical times, and people have looked longingly to a lost Golden Age in history, myth or religion throughout recorded history. The theory of cultural evolution has had ramifications for both concepts, while in some respects seeming inimical to them. Now aspects of these three ideas are having spiritual implications for a large number of people. Examining the connections between them and contemporary religiosity can therefore provide useful insights towards our understanding of the present phenomena. 相似文献

Relating print and speech: the effects of letter names and word position on reading and spelling performance 总被引:3,自引:0,他引:3
From an early age, children can go beyond rote memorization to form links between print and speech that are based on letter names in the initial positions of words (Treiman & Rodriguez, 1999; Treiman, Sotak, & Bowman, 2001). For example, children's knowledge of the name of the letter t helps them learn that the novel word TM is pronounced as team. Four experiments were carried out to determine whether letter names at the ends of words are equally useful. Four- and five-year-olds derived little benefit from such information in reading (Experiments 1 and 3) or spelling (Experiment 2), although adults did (Experiment 4). For young children, word-final information appears to have less influence on reading and spelling performance than does word-initial information. The results help delineate the circumstances under which children can go beyond a logographic approach in learning about print. 相似文献

This study examined the effects of noncontingent reinforcement (NCR) with and without extinction on problem behavior and stimulus engagement (consumption of reinforcement) of 4 participants. Reductions in problem behavior using NCR have frequently been attributed to both satiation of the reinforcer and extinction. In the current study, aspects of the NCR treatment effects were difficult to explain based solely on either a satiation or an extinction account. Specifically, it was found that stimulus engagement remained high throughout the NCR treatment analysis, and that problem behavior was reduced to near-zero levels during NCR without extinction. The implications of these findings are discussed with respect to the satiation and extinction hypotheses frequently described in the applied literature. Findings from basic studies examining the effects of response-independent schedules are presented, and are used as the basis for a matching theory account of NCR-related effects. It is proposed that reductions in problem behavior observed during NCR interventions may be a function of the availability of alternative sources of reinforcement. 相似文献

Women are more likely to employ landmark-based strategies when navigating, and they are superior at employing this type of strategy. The cause of this sexually dimorphic behaviour is unknown. Seventy-nine undergraduates performed a matrix navigation task wherein the symbols within the matrix were highly nameable. Participants were either given landmark-based or Euclidean-based instructions for navigation within the matrix. During navigation, participants were subjected to either articulatory or spatial interference. The articulatory interference selectively impaired women's ability to navigate correctly, regardless of the type of instruction. The performance of the men was not affected differentially by the two types of interference. When given a test of symbol recognition following the navigation task, women recognized more of the symbols employed in the task. Collectively, this result suggests that women rely on linguistic information more than men do when navigating, regardless of the type of instruction. 相似文献
