Two experiments examined whether associating an imitation task with an operant task affected 6-month-olds' memory for either task. Results indicated that infants successfully imitated a puppet's action for up to 2 weeks only if the associated operant task (pressing a lever to activate a miniature train) was retrieved first. Follow-up study…

In the past, some teachers treated word learning as an isolated subject--a list of words that were not connected to content or literature studies. This article describes how Candy Mulligan, a teacher at the Center for Reading and Writing at Rider University in Lawrenceville, NJ, teaches vocabulary by selecting words from the students' seventh and…

In 2 experiments, the authors investigated phonologically mediated priming of preexisting and new associations in word retrieval. Young and older adults completed paired word stems with the first word that came to mind. Priming of preexisting associations occurred when word-stem pairs containing homophones (e.g., beech-s____) showed more…

In two human skin conductance conditioning experiments we investigated whether processing of stimulus compounds can be influenced by past experience. Participants were either pre-trained with a discrimination problem that could be solved elementally (A+, B-, AB+, C- in Experiment 1 and A+, AB+, C-, CB- in Experiment 2) or one that required a…

This paper presents a row-column (RC) association model in which the estimated row and column scores are forced to be in agreement with a priori specified ordering. Two efficient algorithms for finding the order-restricted maximum likelihood (ML) estimates are proposed and their reliability under different degrees of association is investigated by…

One of the most important connections that must be made during the middle school years is the relationship between scientific inquiry and algebraic thinking. Fortunately, there are plenty of ways in which teachers in both mathematics and science can make this intrinsically important association for students. One way is by studying rate of change,…

The less-complex central nervous system of many invertebrates make them attractive for not only the molecular analysis of the associative learning and memory, but also in determining how neural circuits are modified by learning to generate changes in behavior. The nudibranch mollusk "Hermissenda crassicornis" is a preparation that has contributed…

Recent evidence suggests a close functional relationship between memory formation in the hippocampus and dopaminergic neuromodulation originating in the ventral tegmental area and medial substantia nigra of the midbrain. Here we report midbrain activation in two functional MRI studies of visual memory in healthy young adults. In the first study,…

Little is known about signaling mechanisms underlying temporal associative learning. Here, we show that mice with a targeted point mutation that prevents autophosphorylation of [alpha]CaMKII ([alpha]CaMKII[superscript T286A]) learn trace eyeblink conditioning normally. This forms a sharp contrast to the severely impaired spatial learning in the…

Synapsins are evolutionarily conserved, highly abundant vesicular phosphoproteins in presynaptic terminals. They are thought to regulate the recruitment of synaptic vesicles from the reserve pool to the readily-releasable pool, in particular when vesicle release is to be maintained at high spiking rates. As regulation of transmitter release is a…

This article presents a novel approach to teaching business ethics to college students by relying on well-known aids to learning new, complex, and/or abstract material. The primary purpose of this article is threefold: (a) to explore some of the reasons why learning the basics of moral philosophies is relatively difficult for many students; (b) to…

In the present study, we have applied a word association procedure for assessing conceptual change in science education, leaning on the presuppositions of the theory of social representations. The proposed method was applied both before and after a university population ecology course. Our results have shown that the teaching procedure can change…

This paper examines the semantic associations of words found in the business lexical environment by using a one-million word corpus of both spoken and written Business English. The key method of analysis is that of semantic prosody or semantic association; the notion that words associate with collocates that are themselves related, often either…

Nurr1 expression is up-regulated in the brain following associative learning experiences, but its relevance to cognitive processes remains unclear. In these studies, rats initially received bilateral hippocampal infusions of control or antisense oligodeoxynucleotides (ODNs) 1 hour prior to training in a holeboard spatial discrimination task. Such…

A study was conducted to test the hypothesis that high-variability rehearsal more effectively facilitates word recall than does low-variability rehearsal. Third-grade and sixth-grade students were asked to memorize a list of 20 common words. A read-aloud rehearsal procedure was used so that rehearsal could be experimentally controlled. One word…
