This assumption was assessed in two experiments with manipulations that smoothed (Experiment 1) or interrupted (Experiment 2) the gradient between textures comprising L- and X-type micropatterns. Compared to discrimination performance when there was an abrupt discontinuity between juxtaposed textures, performance declined moderately (about 10 percent) when the texture boundary was smoothed. In this case the two textures were asymmetrically discriminated but there was no interaction of this asymmetry with the abruptness of the texture gradient. Abrupt texture gradients, therefore, are not a necessary condition for the asymmetrical discrimination of two textures. A comparison of discrimination performance with juxtaposed textures--having an abrupt gradient--and discrimination performance when the textures were separated into distinct regions--by non-textured areas--yielded very similar results across several texture pairs. Taken together these results indicate that, in certain instances, texture discrimination may involve pattern classification-like processes that are operative in the absence of texture gradients.","PeriodicalId":75671,"journal":{"name":"Canadian journal of psychology","volume":"46 2","pages":"306-32"},"PeriodicalIF":0.0,"publicationDate":"1992-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1037/h0084319","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12620982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent versions of template theories (e.g., Ullman, 1989; Lowe, 1987) assume that these invariances are achieved through the application of transformations such as rotation, translation, and scaling of the image so that it can be matched metrically to a stored template. Presumably, such transformations would require time for their execution. We describe recent priming experiments in which the effects of a prior brief presentation of an image on its subsequent recognition are assessed. The results of these experiments indicate that the invariance is complete: The magnitude of visual priming (as distinct from name or basic level concept priming) is not affected by a change in position, size, orientation in depth, or the particular lines and vertices present in the image, as long as representations of the same components can be activated. An implemented seven layer neural network model (Hummel & Biederman, 1992) that captures these fundamental properties of human object recognition is described. Given a line drawing of an object, the model activates a viewpoint-invariant structural description of the object, specifying its parts and their interrelations. Visual priming is interpreted as a change in the connection weights for the activation of: a) cells, termed geon feature assemblies (GFAs), that conjoin the output of units that represent invariant, independent properties of a single geon and its relations (such as its type, aspect ratio, relations to other geons), or b) a change in the connection weights by which several GFAs activate a cell representing an object.","PeriodicalId":75671,"journal":{"name":"Canadian journal of psychology","volume":"46 2","pages":"191-214"},"PeriodicalIF":0.0,"publicationDate":"1992-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1037/h0084317","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12620978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the literature about these nonaccidental properties (NAPs) is reviewed to trace its historical roots, to list the properties that function as NAPs, and to discuss the psychological evidence for their detection and use. Against this background, four experiments are reviewed and four are fully described that were designed to test the perceptual use of skewed symmetry (SS), which results from orthographic projection of planar bilateral or mirror symmetry (BS). Despite the large symmetry advantage obtained in all experiments, SS is only perceived as BS-in-depth in cases of closed polygons or dot patterns with higher-order types of symmetry. In all random dot patterns and in some symmetric patterns with low \"Gestalt\", subjects relied on more local groupings which are qualitatively affine invariant, such as clusters based on proximity or curvilinearity. Based on previous approaches in the literature and these new findings, I suggest some distinctions between different ways of using NAPs, which might foster further research.","PeriodicalId":75671,"journal":{"name":"Canadian journal of psychology","volume":"46 2","pages":"236-79"},"PeriodicalIF":0.0,"publicationDate":"1992-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1037/h0084323","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12620980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children were tested individually on eight proportionality problems presented with the balance-scale task. Cognitive development was assessed by the strategy used and the performance on each problem. The indicators of self-monitoring were: latencies before and after the solution of a problem, self-evaluation of one's ability to make the balance scale stay level, proportion of oriented moves on the balance scale, and persistence on a problem. Children's self-monitoring reactions to failure were assessed by changes in strategies, verbal explanations, self-evaluation of performance, and latencies. Results showed an interaction between the complexity of the items and cognitive level. On more complex items, children of lower cognitive levels had shorter latencies, made more (but less oriented) moves on the balance scale, persisted less in their activity, and had more difficulty to evaluate properly their performance. Following failure, children of lower cognitive levels did a less accurate evaluation of their performance, modified their strategy, and did not change their verbal justification, whereas children of higher cognitive levels did a good evaluation of their performance, did not change their strategy, and had the tendency to change their verbal justification. Following failure, all children took less time planning their activity. The results suggest that self-monitoring abilities develop according to the development of cognitive strategies and are mediated by the complexity of the task.","PeriodicalId":75671,"journal":{"name":"Canadian journal of psychology","volume":"46 1","pages":"117-37"},"PeriodicalIF":0.0,"publicationDate":"1992-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12758855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
