This study tested four theoretical models in terms of their fit with demands placed on our cognitive system by traditional tests of cognitive ability. We did so by administering seven tests of cognitive ability known to require varying types of processing demands to a large group of college undergraduates (N=193). We compared the models using…

This article aims to provide a theoretical framework to elucidate the neurophysiological underpinnings of deviance detection as reflected by mismatch negativity. A six-step model of the information processing necessary for deviance detection is proposed. In this model, predictive coding of learned regularities is realized by means of long-term…

This study addresses the question of why spellings determined by morphology are relatively hard to acquire by presenting a latent class model of children's acquisition of a doublet of consonants in the spelling of Dutch verbs. This spelling pattern can be determined either by a phonological rule (after a short vowel, a doublet is spelled) or a…

Cognitive processes are often attributed to statistical or symbolic general-purpose mechanisms. Here we show that some spontaneous generalizations are driven by specialized, highly constrained symbolic operations. We explore how two types of artificial grammars are acquired, one based on repetitions and the other on characteristic relations…

Memory for feature binding comprises a key ingredient in coherent object representations. Previous studies have been equivocal about human capacity for objects in the visual working memory. To evaluate memory for feature binding, a type identification paradigm was devised and used with a multiple-object permanence tracking task. Using objects…

The nature of persisting spreading activation from list presentation in eliciting false recognition in the Deese-Roediger-McDermott (DRM) paradigm was examined in two experiments. We compared the time course of semantic priming in the lexical decision task (LDT) and false alarms in speeded recognition under identical study and test conditions. The…

Walking without vision results in veering, an inability to maintain a straight path that has important consequences for blind pedestrians. In this study, the authors addressed whether the source of veering in the absence of visual and auditory feedback is better attributed to errors in perceptual encoding or undetected motor error. Three…

The authors conducted a grounded theory study of academic procrastination to explore adaptive and maladaptive aspects of procrastination and to help guide future empirical research. They discuss previous research on the definition and dimensionality of procrastination and describe the study in which interview data were collected in 4 stages,…

Artificial grammar learning (AGL) is one of the most commonly used paradigms for the study of implicit learning and the contrast between rules, similarity, and associative learning. Despite five decades of extensive research, however, a satisfactory theoretical consensus has not been forthcoming. Theoretical accounts of AGL are reviewed, together…

Metacognition is a concept in psychology that refers to a variety of self-awareness process that help learners learn better. It grew out of the developments over the past few decades of cognitive models of learning. This paper presents a brief overview of these models and discusses their main features. It begins with a discussion of behavioristic…

Purpose: Although the notion of wisdom confronts the economic rationale of business organizations, this paper aims to argue that organizations are coming under increasing pressure not only to learn, change and adapt, but also to take actions that are ethically acceptable and respond to the expectations of multiple stakeholders, or in other words…

We propose an integration of aspects of several developmental and systems of beliefs models of personal epistemology. Qualitatively different positions, including realism, dogmatism, skepticism, and rationalism, are characterized according to individuals' beliefs across three dimensions in a model of epistemic and ontological cognition. This model…

Wikis provide new opportunities for learning and for collaborative knowledge building as well as for understanding these processes. This article presents a theoretical framework for describing how learning and collaborative knowledge building take place. In order to understand these processes, three aspects need to be considered: the social…

The masked priming paradigm was used to examine the role of the root and verb pattern morphemes in lexical access within the verb system of Arabic. Three groups participated in the study: grade 6 dyslexics, a reading-level-matched group and grade 6 normal readers. The first group consisted of: 28 grade 6 reading disabled (RD) students, 8 girls and…

Some children with autism demonstrate poor nonword repetition--a deficit considered to be a psycholinguistic marker of specific language impairment (SLI). The present study examined whether there is an SLI subtype among children with autism. We compared the language abilities of children with SLI (n = 34, M age = 11;10 S.D. = 2;3), and children…
