Small Sets of Novel Words Are Fully Retained After 1-Week in Typically Developing Children and Down Syndrome: A Fast Mapping Study.

J Int Neuropsychol Soc 2018 Oct;24(9):955-965

Department of Psychology,University of Arizona,Tucson,Arizona.

Objectives: Down syndrome (DS) is a population with known hippocampal impairment, with studies showing that individuals with DS display difficulties in spatial navigation and remembering arbitrary bindings. Recent research has also demonstrated the importance of the hippocampus for novel word-learning. Based on these data, we aimed to determine whether individuals with DS show deficits in learning new labels and if they may benefit from encoding conditions thought to be less reliant on hippocampal function (i.

Executive Skills and Academic Achievement in the Dystrophinopathies.

J Int Neuropsychol Soc 2018 Oct;24(9):928-938

1The Graduate Center,City University of New York,Queens College,Queens,New York.

Objectives: To examine academic performance in dystrophinopathy as a function of dystrophin gene mutation position as well as intellectual function, executive skills, socioeconomic status (SES), behavior, and physical ability.

Methods: In a cross-sectional study, boys with dystrophinopathy (ages 5-17; n=50) completed tests of academics (Woodcock-Johnson-III: spelling, reading, calculation and total scores), executive functioning (selective attention/inhibitory control, set shifting, working memory, and processing speed), single word comprehension and nonverbal reasoning. Motor skills were assessed and parents provided demographic information and child behavioral assessments. Read More

Deleterious Impact of Expressive Suppression on Test Performance Persists at One-Year Follow-Up in Community-Dwelling Older Adults.

J Int Neuropsychol Soc 2019 Jan 26;25(1):29-38. Epub 2018 Oct 26.

1Department of Psychology,University of Utah,Salt Lake City,Utah.

Objectives: Expressive suppression (ES) is an emotion-regulation strategy that is associated with poorer performance on subsequently administered tests of executive functioning (EF). It is not known, however, how far into the future ES interferes with EF. This study examined whether (a) ES negatively affects performance on EF tests repeated 1 year after the initial administration (presumably through interference with learning, leading to a reduced practice effect), and (b) whether such an effect, if seen, is unique to EF or whether it also affects lower-order cognitive processes needed for EF test performance.

Effects of Bilingualism on Verbal and Nonverbal Memory Measures in Mild Cognitive Impairment.

J Int Neuropsychol Soc 2019 Jan 18;25(1):15-28. Epub 2018 Oct 18.

21Florida Alzheimer's Disease Research Center,Miami Beach,Florida.

Objectives: Maintaining two active languages may increase cognitive and brain reserve among bilingual individuals. We explored whether such a neuroprotective effect was manifested in the performance of memory tests for participants with amnestic mild cognitive impairment (aMCI).

Methods: We compared 42 bilinguals to 25 monolinguals on verbal and nonverbal memory tests. Read More

Executive Functioning Correlates With Communication Ability in Youth With Histories of Heavy Prenatal Alcohol Exposure.

J Int Neuropsychol Soc 2018 Nov 16;24(10):1026-1037. Epub 2018 Oct 16.

1Center for Behavioral Teratology and Department of Psychology,San Diego State University,San Diego,California.

Objectives: Caregivers of youth with heavy prenatal alcohol exposure report impaired communication, which can significantly impact quality of life. Using data collected as part of the Collaborative Initiative on Fetal Alcohol Spectrum Disorders (CIFASD), we examined whether cognitive variables predict communication ability of youth with histories of heavy prenatal alcohol exposure.

Methods: Subjects (ages 10-16 years) comprised two groups: adolescents with heavy prenatal alcohol exposure (AE) and non-exposed controls (CON). Read More

Evaluating Mild Cognitive Impairment in Essential Tremor: How Many and Which Neuropsychological Tests?

J Int Neuropsychol Soc 2018 Nov 10;24(10):1084-1098. Epub 2018 Oct 10.

4Department of Neurology,College of Physicians and Surgeons,Columbia University,New York,New York.

Objectives: Essential tremor (ET) confers an increased risk for developing both amnestic and non-amnestic mild cognitive impairment (MCI). Yet, the optimal measures for detecting mild cognitive changes in individuals with this movement disorder have not been established. We sought to identify the cognitive domains and specific motor-free neuropsychological tests that are most sensitive to mild deficits in cognition as defined by a Clinical Dementia Rating (CDR) of 0.

Automated Indices of Clustering and Switching of Semantic Verbal Fluency in Parkinson's Disease.

J Int Neuropsychol Soc 2018 Nov 4;24(10):1047-1056. Epub 2018 Oct 4.

1Toronto Western Hospital,University Health Network,Toronto,Canada.

Objectives: Deficits in semantic verbal fluency (SVF) can stem from dysfunction of an executive control system and/or of semantic knowledge. Previous analyses of SVF responses were devised to characterize these two components including switching and mean cluster size (MCS) indices, but these rely on subjective experimenter-based assessment of the words' relatedness. To address this limitation, computational data-driven SVF indices have been developed. Read More

Increasing Inaccuracy of Self-Reported Subjective Cognitive Complaints Over 24 Months in Empirically Derived Subtypes of Mild Cognitive Impairment.

J Int Neuropsychol Soc 2018 Sep;24(8):842-853

1Veterans Affairs San Diego Healthcare System,San Diego,California.

Objectives: Although subjective cognitive complaints (SCC) are an integral component of the diagnostic criteria for mild cognitive impairment (MCI), previous findings indicate they may not accurately reflect cognitive ability. Within the Alzheimer's Disease Neuroimaging Initiative, we investigated longitudinal change in the discrepancy between self- and informant-reported SCC across empirically derived subtypes of MCI and normal control (NC) participants.

Methods: Data were obtained for 353 MCI participants and 122 "robust" NC participants. Read More
