Effect of visual presentation format and recall direction on letter span and error patterns in Deaf signing and hearing adults.

Deaf signers consistently show shorter memory spans than hearing nonsigners, but the scope and nature of this difference remain unclear. The present study tested whether Deaf signers are biased toward flexible use of visual aspects of linguistic items. Matched samples of adult Deaf signers (N = 33) and hearing nonsigners (N = 32) performed a letter-span task with visual serial presentation, to bias phonological processing, and a simultaneous presentation, to bias visuospatial processing.

Neurophysiologic evidence for increased retrieval suppression among negative ruminators.

Introduction: Events (e.g., seeing a familiar face) may initiate retrieval of associated information (e.

Exploring the Specificity, Synergy, and Durability of Auditory and Visual Computer Gameplay Transfer Effects in Healthy Older Adults.

Objectives: To determine whether auditory and visual computer games yield transfer effects that (a) are modality-specific to verbal memory (auditory stimulus presentation) and visual-processing tests, (b) affect working memory and processing speed, (c) are synergistic for combined game-type play, and (d) are durable.

Method: A Pilot Study (N = 44) assessed visual transfer effects in a two-group pre-post design. The Main Study (N = 151) employed a 2 (visual games: yes, no) × 2 (auditory games: yes, no) × 3 (test session: pretest, post-test, follow-up) design, allowing different training groups to act as active controls for each other.

Cortical Measures of Motor Planning and Balance Training in Patients With Chronic Ankle Instability.

Context: Motor planning, a prerequisite for goal-driven movement, is a complex process that occurs in the cortex. Evidence has suggested that motor planning is altered in patients with chronic ankle instability (CAI). We know balance training can improve balance, but we do not know if it also improves motor planning.

Assessment of Cognitive Training & Social Interaction in People with Mild to Moderate Dementia: A Pilot Study.

: To evaluate the cognitive, neuropsychiatric, and quality of life outcomes of computer-based cognitive training and social interaction on people with mild to moderate dementia. : Ten individuals with dementia were recruited to complete a cognitive training regimen. They were randomly assigned to a high social interaction (HSI) group (n = 5) and low social interaction (LSI) group (n = 5).

Effectiveness of cognitive rehabilitation following acquired brain injury: a meta-analytic re-examination of Cicerone et al.'s (2000, 2005) systematic reviews.

The present study provides a meta-analysis of cognitive rehabilitation literature (K = 115, N = 2,014) that was originally reviewed by K. D. Cicerone et al.

Phonological blocking during picture naming in dementia of the Alzheimer type.

Individuals with dementia of the Alzheimer type (DAT; n = 53, ages 55-91), healthy older adults (n = 75, ages 59-91), and younger adults (n = 24, ages 18-24) performed a word-primed picture-naming task. Word primes were neutral (ready), semantically or phonologically related, or unrelated to the correct picture name. AH groups produced equivalent unrelated-word interference and semantic priming effects in response latencies.

Exploring semantic memory by investigating buildup and release of proactive interference in healthy older adults and individuals with dementia of the Alzheimer type.

There is debate regarding the integrity of semantic memory in dementia of the Alzheimer type (DAT). One view argues that DAT is associated with a breakdown in semantic memory; the other argues that DAT is associated with predominantly preserved semantic memory and a breakdown in retrieval. The classic release from proactive interference (RPI) paradigm was used to shed light on this debate.
