A possible role of the cerebellum in detecting and recognizing event sequences has been proposed. The present study sought to determine whether patients with cerebellar lesions are impaired in the acquisition and discrimination of sequences of sensory stimuli of different modalities. A group of 26 cerebellar patients and 26 controls matched for…

Cannabinoid receptors type 1 (CB1) play a central role in both short-term and long-term extinction of auditory-cued fear memory. The molecular mechanisms underlying this function remain to be clarified. Several studies indicated extracellular signal-regulated kinases (ERKs), the phosphatidylinositol 3-kinase with its downstream effector AKT, and…

The widely used Pavlovian fear-conditioning paradigms used for studying the neurobiology of learning and memory have mainly used auditory cues as conditioned stimuli (CS). The present work assessed the neural network involved in olfactory fear conditioning, using olfactory bulb stimulation-induced field potential signal (EFP) as a marker of…

Recent CALL research has started to go beyond the comparison of CALL versus non-CALL environments to explore what learners do while going through CALL activities. One important strand within that area has focused on the use and utility of providing learners with opportunities to request modified input. While many studies have carried out research…

It has been suggested that specific reading disability (SRD) may be attributable to an impaired ability to perceive spectral differences between sounds that leads to a deficit in frequency discrimination and subsequent problems with language and literacy. The objective of the present study was threefold. We aimed to (a) determine whether children…

Recent debate regarding dual-task performance has focused on whether costs result from limitations in central capacity, and whether central operations can be performed in parallel. While these questions are controversial, the dominant models of dual-task performance share the assumption that central operations are generic--that is, their…

The effect of the use of interactive videodisc technology to present aural tests was studied in the context of college music appreciation classes. Both experimental and control groups were given study guides that identified the aural objectives for each test and specified the location of the musical examples that were to be used to illustrate the…

Teaching activities are suggested for the development of aural language programs. (JH)

A study examined the effects of visual-verbal redundancy and recaps on learning from television news. Two factors were used: redundancy between the visual and audio channels, and the presence or absence of a recap. Manipulation of these factors created four conditions: (1) redundant pictures and words plus recap, (2) redundant pictures and words…

Designed for professionals who design and develop instructional materials, this paper identifies specific and general strategies that educational technologists can employ in their media productions to enhance aesthetic awareness. A brief overview of aesthetics and aesthetic education is provided, including definitions and various approaches to…

This study investigated the effects of distractors on children's task-relevant (central) and task-irrelevant (incidental) recall on a short term visual memory task involving pictures of familiar animals and household articles. The effect of mode of distractor (auditory or visual) and the effect of developmental level were also studied. Subjects…

This paper discusses a series of three studies investigating the influence of infants' characteristics and signaling behavior on parents. Videotapes of either smiling/cooing/gurgling or crying infants were used to elicit parents' physiological and affective responses. Measured physiological responses included skin conductance, heart rate, and…

INTERACTION BETWEEN VISION AND HEARING WERE STUDIED IN 35 SPEECH HANDICAPPED FIRST-GRADE CHILDREN. THE ABILITY TO SHIFT ATTENTION FROM ONE SENSORY MODALITY TO ANOTHER WAS LABELED AS "PERCEPTUAL SHIFTING." A DEVICE DEVELOPED BY EXPERIMENTAL PSYCHOLOGISTS PRESENTED VARIOUS STIMULI TO EACH SUBJECT AND RECORDED THE SUBJECT'S REACTION TIME.…

Suggestions for the effective use of the dialog in audiolingual language classes include descriptions of (1) planned preliminary activities, (2) method of presenting and drilling dialog lines, and (3) the instructional potential of mastered material. Significant emphasis is placed on practices advocated by Gaarder. (AF)

Sixty kindergarten and sixty second grade children were administered a paired-associate (P-A) task. The subjects in each age group were randomly assigned to one of four groups: (1) experimental with aural presentation of the P-A's, (2) experimental with visual presentation of the P-A's, (3) control with aural presentation of the P-A's and (4)…
