This report investigates the relations between duration of examining and heart rate (HR) across several trials of an object-examination task. A total of N= 20 11-month-olds were familiarized with a sequence of 10 different exemplars from the same global category (animals or furniture) before they received an exemplar from the contrasting category…

CF-1 male mice were trained in an inhibitory avoidance task using a high footshock (1,2 mA, 50 Hz, 1 sec) in order to reduce the influence of extinction on retention performance. At 2, 7, 14, or 30 d after training, the first retention test was performed and hemicholinium (HC-3, 1.0 microgram/mice), a specific inhibitor of high-affinity choline…

The dentate gyrus (DG) subregion of the hippocampus has been shown to be involved in encoding but not retrieval in a spatial maze task (modified Hebb-Williams maze). The first experiment in this study examined whether a lesion to the CA3 would contribute to a similar encoding deficit. A DG group was included in order to replicate previous results.…

To investigate the stability of trace reactivation in healthy older adults, 22 older volunteers with no significant neurological history participated in a cross-modal priming task. Whilst both object relative center embedded (ORC) and object relative right branching (ORR) sentences were employed, working memory load was reduced by limiting the…

Organizing the work of instructional improvement around a process that has specific, manageable steps helps educators build confidence and skill in using data. A process that includes eight distinct steps can take school leaders to use their assessment data effectively, and organized these steps into three phases: Prepare, Inquire, and Act. The…

A delayed matching-to-sample task with multiple sample stimuli was used to evaluate stimulus overselectivity in 70 individuals attending residential special-education schools. A Mental Age Equivalent score (MAE) was obtained for each student using the Peabody Picture Vocabulary Test. Twenty-one participants failed to complete matching-to-sample…

Differences in performance with various stimulus-response mappings are among the most prevalent findings for binary choice reaction tasks. The authors show that perceptual or conceptual similarity is not necessary to obtain mapping effects; a type of structural similarity is sufficient. Specifically, stimulus and response alternatives are coded as…

Some potential contributions of invariants, heuristics, and exemplars to the perception of dynamic properties in the colliding balls task were explored. On each trial, an observer is asked to determine the heavier of 2 colliding balls. The invariant approach assumes that people can learn to detect complex visual patterns that reliably specify…

Recently, there has been increased attention to the development of complex syntax by children with language disorder. An example is the work of Schuele and Nicholls and Schuele and Tolbert who describe the acquisition of relative clauses by a group of children with SLI. The current paper presents data from 66 children with language impairment,…

Most current models of speech production predict interference from related context words in picture-naming tasks. However, Glaser and Dungelhoff (1984) reported semantic facilitation when the task was changed from basic-level naming to category-level naming. The authors explore two proposals to account for this change in polarity of the semantic…

Previously it has been reported that female performance on the recall of objects and their locations in a spatial array is superior to that of males. This may reflect underlying information-processing biases whereby males organize information in a self-referential manner while females adopt a more comprehensive approach. The known female advantage…

For the first time, the annual conference of the European Association for Computer-Assisted Language Learning (EUROCALL) took place in Sweden. The conference took place at the Faculty of Education on historic ground on the old fortification walls of Carolus Dux from the 17th century right in the centre of the city. This year's host comprised the…

Though cognitive science has given psychology a new, more detailed and specific way of expressing models of cognition, correspondingly detailed and precise arguments analyzing and supporting those models have not been forthcoming. Consequently, the new models often fail to meet the traditional criteria of scientific theories. Tools are available…

This document describes an instructional analysis technique believed to be an expedient and effective alternative to the Gagne-Briggs model because, among other reasons, it is easier to teach to novice trainers. The technique is in use in the U.S. Marine Corps. The document consists of the following: an overview of the different kinds of analysis…
