ABSTRACTIn four experiments, we examined the sources of metacognitive judgments during the categorisation of new items after the learning of old items was completed. In the rule condition, the categorisation rule was explicitly given to the participants during learning, while in the no-rule condition participants relied on feedback to infer category membership. In the transfer phase, two types of novel items were used: good and bad transfer items. Transfer items also differed in the level of sim...

Huang and Pashler [2007, Psychological Review, 114(3), 599-631] suggested that feature-based attention creates a special form of spatial representation, which is termed a Boolean map. It partitions the visual scene into two distinct and complementary regions: selected and not selected. Here, we developed a model of a recurrent competitive network that is capable of state-dependent computation. It selects multiple winning locations based on a joint top-down cue. We augmented a model of the WTA ci...

Abstract. In two experiments, we showed that irrelevant numerical information influenced the speed of sentence-picture verification. Participants were asked to verify whether the concept mentioned in a sentence matched the object presented in a subsequent picture. Concurrently, the number word attached to the concept in the sentence and the quantity of objects presented in the picture were manipulated (numerical congruency). The number of objects varied from one to four. In Experiment 1, partici...

The aim of the study was to investigate the influence of item similarity on classification accuracy and confidence judgments in categorization tasks with two mutually exclusive categories defined by a simple or a complex rule. Two experiments using pictorial stimuli that varied on five binary-valued dimensions were conducted. In Experiment 1 (N=71) stimuli were colored arrows presented on a background similar to those used by Waldron and Ashby (2001). In Experiment 2 (N=64) stimuli were drawings...

Category learning can be an explicit process when the rule that defines category membership is available, or an implicit process of slow associating members to categories when the rule is not known. The empirical question is whether the implicit process of learning categories can be facilitated by explicitly informing participants to direct their attention on relevant aspects of the category members in situation when the correct rule is not discovered. In this study, we examined whether classifi...

In two experiments, we examined the correspondence between the dynamics of metacognitive judgments and classification accuracy when participants were asked to learn category structures of different levels of complexity, i.e., to learn tasks of types I, II and III according to Shepard, Hovland, and Jenkins (1961). The stimuli were simple geometrical figures varying in the following three dimensions: color, shape, and size. In Experiment 1, we found moderate positive correlations between confidenc...
