An associative model of serial learning is described based on the assumption that the effective stimulus for a serial-list item is generated by adaptation-level coding of the item's ordinal position. How the model can generate predictions of aspects of serial-learning data is illustrated. (SLD)

Two experiments examined role of affective correspondence between signal and outcome in 4-month olds' associative learning. Found that only when consoling infant-directed speech signaled the sad face did infants' visual interest in a checkerboard increase. Arousing infant-directed speech signaling either the smiling or sad face produced positive…

A word association experiment examined conceptual representation in bilingual memory. Dutch-English bilinguals associated twice to nouns and verbs that varied on concreteness and cognate status. Findings suggest that conceptual representation in bilingual memory depends on word-type and grammatical class: concrete translations, cognates, and noun…

We examine the influence of inferring interlocutors' referential intentions from their body movements at the early stage of lexical acquisition. By testing human participants and comparing their performances in different learning conditions, we find that those embodied intentions facilitate both word discovery and word-meaning association. In…

Idiom comprehension was assessed in 10 aphasic patients with semantic deficits by means of a string-to-picture matching task. Patients were also submitted to an oral explanation of the same idioms, and to a word comprehension task. The stimuli of this last task were the words following the verb in the idioms. Idiom comprehension was severely…

The orbitofrontal cortex contains the secondary taste cortex, in which the reward value of taste is represented. It also contains the secondary and tertiary olfactory cortical areas, in which information about the identity and also about the reward value of odours is represented. The orbitofrontal cortex also receives information about the sight…

The murine vibrissae sensorimotor system has been scrutinized as a target of motor learning through trace classical conditioning. Conditioned eyelid responses were acquired by using weak electrical whisker-pad stimulation as conditioned stimulus (CS) and strong electrical periorbital stimulation as unconditioned stimulus (US). In addition,…

We studied the effects of a selective lesion in rats, with 192-IgG-saporin, of the cholinergic neurons located in the medial septum/diagonal band (MSDB) complex on the acquisition of classical and instrumental conditioning paradigms. The MSDB lesion induced a marked deficit in the acquisition, but not in the retrieval, of eyeblink classical…

Courtship conditioning is an associative learning paradigm in "Drosophila melanogaster," wherein male courtship behavior is modified by experience with unreceptive, previously mated females. While the training experience with mated females involves multiple sensory and behavioral interactions, the authors hypothesized that female cuticular…

This study investigates the effectiveness of three methods of learning vocabulary among 778 beginning second language (L2) learners. Rote memorization consists of memorizing the first language (L1) translation of a new L2 word by rehearsal. Semantic mapping displays L1 words conceptually related to the L2 word in a diagram. The keyword method…

Semantic priming refers to a reduction in the reaction time to identify or make a judgment about a stimulus that has been immediately preceded by a semantically related word or picture and is thought to result from a partial overlap in the semantic associates of the two words. A semantic priming lexical decision task using spoken words was…

Classical fear conditioning requires the recognition of conditioned stimuli (CS) and the association of the CS with an aversive stimulus. We used Affymetrix oligonucleotide microarrays to characterize changes in gene expression compared to naive mice in both the amygdala and the hippocampus 30 min after classical fear conditioning and 30 min after…

What is a routine question? The focus of this paper is routine questions and time (in years) since a hitherto routine question was last attempted by the solver. The data comes from undergraduate students' work on solving two calculus questions. The data was selected for reporting purposes because it is well documented and because it threw up…

Electronic portfolios allow students to include video, images, hyperlinks, and audio, along with written texts, to create varied and comprehensive representations of what they have accomplished. Such collections of information also change the ways that teachers and students choose to present themselves and the ways that we read these presentations…

This report described and analyzed different methods for constructing a student's cognitive map in order to study the development and use of domain-specific prior knowledge. Cognitive maps provide accounts of student trajectories over courses and individual or group profiles of learners' strengths and weaknesses at the course or multicourse level.…
