OBJECTIVE: Closing-in behavior (CIB) defines the abnormal misplacement of the copy performance, positioned very closed to or on the top of the model. This symptom is observed in graphic copying by patients suffering from different neurological diseases, most commonly dementia. The cognitive origins of this behavior are still a matter of investigation, and research of the last 10 years has been focused on exploring 2 main accounts of CIB, the compensation and the attraction hypotheses, providing evidence in both directions...

OBJECTIVE: Decreased processing speed in schizophrenia patients has been identified as a major impairment factor in various neuropsychological domains. Working memory span has been found to be involved in several deep or effortful cognitive processes. We investigated the impact that these 2 cognitive functions may have on phonological and semantic fluency in schizophrenia patients and healthy participants. METHOD: Fifty-five patients with schizophrenia and 60 healthy participants were administered a neuropsychological battery including phonological and semantic fluency, working memory, and cognitive and motor speed...

OBJECTIVE: The authors tested the hypothesis that Parkinson's disease (PD) participants would perform better in an emotion recognition task with dynamic (video) stimuli compared to a task using only static (photograph) stimuli and compared performances on both tasks to healthy control participants. METHOD: In a within-subjects study, 21 PD participants and 20 age-matched healthy controls performed both static and dynamic emotion recognition tasks. The authors used a 2-way analysis of variance (controlling for individual participant variance) to determine the effect of group (PD, control) on emotion recognition performance in static and dynamic facial recognition tasks...

OBJECTIVE: Previous studies have reported that brain-injured patients frequently suffer from cognitive impairments such as attention and concentration deficits. Numerous rehabilitation clinics offer animal-assisted therapy (AAT) to address these difficulties. The authors' aim was to investigate the immediate effects of AAT on the concentration and attention span of brain-injured patients. METHOD: Nineteen patients with acquired brain injury were included in a randomized, controlled, within-subject trial...

OBJECTIVE: To examine associations between executive functioning (EF) and coping styles, separately for mild and moderate-severe traumatic brain injury (TBI) in the chronic phase postinjury. METHOD: Patients with mild (n = 47) and moderate-severe TBI (n = 59) were included, in addition to healthy controls (HCs; n = 51). Assessment consisted of EF tests (Trail Making Test, Zoo Map Test, Controlled Oral Word Association Test) and questionnaires examining EF (Dysexecutive Questionnaire) and coping styles (Utrecht Coping List)...

OBJECTIVE: To examine associations between daytime and insomnia-related sleep problems with different domains of cognitive functioning and determine whether subclinical depressive symptoms and age moderate these associations. METHOD: A total of 903 cognitively healthy older adults enrolled in a longitudinal aging study completed the UDS neuropsychological battery (measuring attention, executive functioning, episodic memory, language and processing speed). Subclinical depressive symptoms were also assessed and self-reported measures of sleep were administered...

OBJECTIVE: This study examined the influence of education, country where education occurred, and monolingual-bilingual (English/Spanish) language usage on late life cognitive trajectories in the Sacramento Area Latino Study on Aging (SALSA), an epidemiological study of health and cognition in Hispanics, mostly of Mexican origin, age 60 and over (N = 1,499). METHOD: SALSA followed a large cohort of older Latinos for up to 7 assessment waves from 1998 to 2007. Global cognition was assessed by using the Modified Mini Mental State Examination, and the Spanish English Verbal Learning Test was used to measure episodic memory...

OBJECTIVE: The primary goal of the current study was to investigate factors contributing to more negative cognitive change at older ages. METHOD: Longitudinal data on 12 cognitive tests were examined in 2,637 adults ranging from 18 to 85 years of age. Because both the intervals between measurement occasions and the number of occasions varied across participants, it was possible to investigate effects of interval and number of measurement occasions on cognitive change in adults of different ages...

OBJECTIVE: We highlight the past 25 years of cognitive neuroscience and neuropsychology, focusing on the impact to the field of the introduction in 1992 of functional MRI (fMRI). METHOD: We reviewed the past 25 years of literature in cognitive neuroscience and neuropsychology, focusing on the relation and interplay of fMRI studies and studies utilizing the "lesion method" in human participants with focal brain damage. RESULTS: Our review highlights the state of localist/connectionist research debates in cognitive neuroscience and neuropsychology circa 1992, and details how the introduction of fMRI into the field at that time catalyzed a new wave of efforts to map complex human behavior to specific brain regions...

OBJECTIVES: Recent studies suggest that intraindividual variability (IIV) of neuropsychological performance may be sensitive to HIV-associated neurologic compromise. IIV may be particularly dependent upon the integrity of frontal-subcortical systems, and therefore may be a meaningful phenotype in HIV. We examined the relationship between change in IIV and white matter integrity among HIV seropositive (HIV+) and HIV seronegative (HIV-) individuals. METHOD: The sample consisted of 38 HIV+ participants and 26 HIV- control participants who underwent neuroimaging and a neuropsychological evaluation at baseline and at 2-year follow-up evaluation...

OBJECTIVE: Fear generalization, the generalization of fear to innocuous stimuli, is a characteristic component of pathological anxiety. Neural models of fear generalization suggest the involvement of the medial prefrontal cortex (mPFC). However, conflicting empirical findings complicate our understanding of the role of the mPFC in pathological anxiety. To address important unanswered questions in this area, a detailed review and synthesis of results from human and nonhuman animal investigations of conditioned fear generalization was conducted...

OBJECTIVE: The last 25 years have seen profound changes in neurocognitive rehabilitation that continue to motivate its evolution. Although the concept of nervous system plasticity was discussed by William James (1890), the foundation for experience-based plasticity had not reached the critical empirical mass to seriously impact rehabilitation research until after 1992. The objective of this review is to describe how the emergence of neural plasticity has changed neurocognitive rehabilitation research...

OBJECTIVE: Research on executive functions (EFs) has revealed evidence for general abilities that underlie performance across multiple EF tasks and domains. This Common EF factor is highly stable in adolescence through young adulthood, correlates with other important cognitive abilities, and is explained largely by genetic influences. However, little is known about Common EF beyond young adulthood. This study examines 3 hypotheses regarding the latent structure, genetic/environmental etiology, and cognitive correlates of Common EF in middle age...

OBJECTIVE: Recent evidence suggests the role of brain-derived neurotrophic factor (BDNF) in the pathophysiology of suicidal behavior. Because schizophrenia patients usually have high suicide rates and numerous studies have suggested that BDNF may contribute to the psychopathology of schizophrenia, we hypothesized that the functional polymorphism of BDNF (Val66Met) was associated with suicide attempts in patients with schizophrenia in a Chinese Han population. METHOD: This polymorphism was genotyped in 825 chronic schizophrenia patients with (n = 123) and without (n = 702) suicide attempts and 445 healthy controls without a history of suicide attempts using a case-control design...

OBJECTIVES: The current fMRI study examined the role of phonology in the extraction of meaning from print in each hemisphere by comparing homophonic and heterophonic homographs (ambiguous words in which both meanings have the same or different sounds respectively, e.g., bank or tear). The analysis distinguished between the first phase, in which participants read ambiguous words without context, and the second phase in which the context resolves the ambiguity. METHOD: Native Hebrew readers were scanned during semantic relatedness judgments on pairs of words in which the first word was either a homophone or a heterophone and the second word was related to its dominant or subordinate meaning...

OBJECTIVE: Famous people knowledge has been shown to be impaired early in Alzheimer's disease (AD) and amnestic mild cognitive impairment (aMCI). However, the question of whether recently acquired knowledge is more impaired than remotely acquired knowledge remains a matter of debate. The aim of this study was to investigate the patterns of semantic memory impairment in aMCI and AD by investigating 2 factors that may influence the retrieval of such knowledge, namely remoteness and frequency of repetition of information over time...

OBJECTIVE: The current study examined whether the arithmetical calculation skills of children, adolescents, and young adults with isolated cleft of the lip and/or palate (iCL/P) differ significantly from unaffected control participants. Comparisons of potential neuropsychological predictors of arithmetical calculation were also conducted to determine whether these variables differ significantly for participants with iCL/P. METHOD: Participants (N = 176; 93 iCL/P and 83 Control) ranged in age from 7 to 26 years old...

OBJECTIVE: The authors investigated whether children with Down's syndrome (DS) who have not started to produce number words understand the one-to-one correspondence principle (Experiment 1), and they looked at the relationship between number word knowledge and receptive vocabulary (Experiment 2). METHOD: Sixteen children with DS who did not recite the count list participated in Experiment 1, along with 2 comparison groups: 1 of 16 children with DS who recited up to 10, paired by chronological age, and another of 16 typically developing children paired by their ability to recite the list...

OBJECTIVE: Research on early cognitive markers of Alzheimer's disease is primarily focused on retrospective recall (of word lists, pairs of items, stories) and executive functions. However, research shows that people with amnestic mild cognitive impairment (aMCI), who are at a higher risk of developing the disease than healthy controls, are particularly impaired in remembering to do things in the future or prospective memory (PM). The aim of this study was to establish which type of event-based PM is particularly disrupted in aMCI, focal PM, based on spontaneous retrieval, or nonfocal PM that relies on strategic monitoring processes...

BACKGROUND: Theory of mind (ToM) is the ability to understand and interpret another person's beliefs, intentions (cognitive ToM) and emotions (affective ToM). OBJECTIVE: To explore affective and cognitive ToM and their neuropsychological correlates in patients affected by multiple sclerosis (MS). MATERIAL AND METHOD: Forty MS patients and 40 matched control individuals underwent tasks assessing cognitive (the ToM Pictures Sequencing Task and the Advanced Test of ToM) and affective ToM (the Reading the Mind in the Eyes Task and the Emotion Attribution Task), in both verbal and nonverbal modality, a comprehensive neuropsychological battery, and questionnaires for behavioral disorders...
