Chronic use of methamphetamine (MA) is associated with neuropsychological dysfunction and affective distress. Some normalization function has been reported after abstinence, but little in the way data available on possible added benefits long-term sobriety. To address this, we performed detailed evaluations 83 MA-dependent individuals at a baseline visit following an average one-year interval period. Among participants, 25 remained abstinent, 58 used MA least once during A total 38...
Optimal adherence to antiretroviral medications is critical the effective long-term management of HIV infection. Although prospective memory (ProM; i.e., "remembering remember") has long been theorized play an important role in medication adherence, no prior studies have evaluated whether HIV-associated ProM impairment possesses unique predictive value this regard. Results from study demonstrate a robust association between and self-reported 87 HIV-infected persons currently prescribed...
Older adults commonly experience declines in prospective memory, which describes one's ability to "remember remember," and can adversely affect instrumental activities of daily living healthcare compliance. However, the extent memory failures may influence quality life typically aging older is not well understood. One-hundred four community-dwelling Australians (aged 50 82 years) were administered a comprehensive, neuropsychological battery that included Memory for Intentions Screening Test...
Executive dyscontrol of episodic verbal learning and memory secondary to prefrontostriatal circuit neuropathophysiology is a common feature HIV-1 infection. Prior research indicates that standard clinical recall indexes from Hopkins Verbal Learning Test-Revised (HVLT-R) are among the most sensitive indicators HIV-associated neurocognitive disorders. Emerging data support validity qualitative component process measures derived HVLT-R (e.g., Semantic Clustering); however, no prior studies have...
Serial assessments of cognitive functioning in individuals with Parkinson's disease (PD) are commonly used for the detection incident dementia and neurobehavioral changes associated treatments using neuromodulation (e.g., deep brain stimulation) pharmacological agents cholinesterase inhibitors). This study provides test-retest stability, expected practice effects, practice-corrected reliable change indices several neuropsychological tests from 62 older adults mostly mild PD who underwent...
The Memory for Intentions Screening Test (MIST) is a clinical measure of prospective memory. There emerging support the sensitivity and ecological relevance MIST in populations. In present study, construct validity was evaluated 40 younger (18-30 years), 24 young-old (60-69 37 old-old (70+ years) healthy adults. Consistent with expectations derived from memory aging literature, older adults demonstrated lower scores on MIST’s primary scale (particularly time-based scale), but slightly better...
Situational factors can influence cognitive performance and should be considered for conducting assessments. The objective of this project was to develop a checklist Cognitive Assessment Requirements (CARE) identify these situational before assessments account them. This study employed four-round Delphi approach involving 22 experts that impact assessment results. development robust well-balanced guided by consensus-driven approach, which metrics such as Interquartile Deviation (IQD) (>...
This study aimed to examine the associations between cognition, skin tone, and stress in a heterogeneous sample of Puerto Rican adults. Participants included 1,502 Ricans from first wave Boston Health Study. Structural equation modeling was used analyze tone groups, stressful life events (i.e., perceived discrimination number adverse events), stress, allostatic load, cognition. The model fit examining relationship cognition excellent even after introducing covariates. When considering also...
The relationship between writing and math achievement is not well understood. Phonological awareness (PA), working memory (WM), fine motor skills (FMS) have been individually linked to theories of math, yet are rarely considered together. current study evaluates the shared cognitive factors underlying performance, both timed (e.g. fluency/automaticity) untimed spelling computation). It does so among third- through fifth-graders (n = 677) who vary in academic abilities. Results revealed...
Strategic monitoring during a delay interval is theorized to be an essential feature of time-based prospective memory (TB PM), the cognitive architecture which thought rely heavily on frontostriatal systems and executive functions. This hypothesis was examined in 55 individuals with HIV-associated neurocognitive disorders (HAND) 108 seronegative comparison participants who were administered Memory for Intentions Screening Test (MIST), time-monitoring (clock-checking) behavior measured....
Older adults with HIV disease demonstrate moderate deficits in time-based prospective memory (PM), which is the strategically demanding ability of remembering to perform a task at specific time. Using theories from PM literature, we hypothesized that supporting strategic processes would improve laboratory among HIV+ older adults.One hundred forty-five participants were randomly assigned control condition or an experimental group processing was supported encoding (i.e., implementation...
For decades, quantitative psychologists have recommended that authors report effect sizes to convey the magnitude and potential clinical relevance of statistical associations. However, fewer than one-third neuropsychology articles published in early 2000s reported sizes. This study re-examines frequency extent size reporting journal by manuscript section over time.A sample 326 empirical were drawn from 36 randomly selected issues six journals at 5-year intervals between 1995 2020. Four...
Objective: Doctoral education is a cornerstone in the training of clinical neuropsychologists. However, we know little about perceptions, practices, and needs faculty who oversee doctoral neuropsychology (CN). Method: Seventy-one from 45 programs providing CN completed at least part survey assessing characteristics their programs, current practices views, challenges to training. Results: Over half reported having zero or only one colleague. that goals are research training, acquisition...
The current study evaluated the reliability and validity of a novel, performance-based banking task in 60 younger (18–34 years) older (50–85 adults. All participants completed Telephone-based Daily Instrumental Activities Living (T-DIAL) using interactive voice response technology to complete series mock actions with financial institution via telephone. T-DIAL showed strong inter-rater internal consistency. accuracy was significantly independently related better self-reported instrumental...
According to the multi-process theory of prospective memory (ProM), time-based tasks rely more heavily on strategic processes dependent prefrontal systems than do event-based tasks. Given prominent frontostriatal pathophysiology HIV infection, one would expect HIV-infected individuals demonstrate greater deficits in versus ProM. However, two prior studies examining this question have produced variable results. We evaluated hypothesis 143 with infection and 43 demographically similar...
Background: Identifying potentially modifiable risk factors for medication non-adherence in older adults is important order to enhance screening and intervention efforts designed improve medication-taking behavior health outcomes. The current study sought determine the unique contribution of prospective memory (PM) (i.e. 'remembering remember') successful self-reported management adults.Methods: Sixty-five with prescriptions completed a comprehensive research evaluation sociodemographic,...
Apathy is common in older adults and has been linked to adverse health outcomes. The current study examined whether apathy contributes problems managing activities of daily living (ADLs) lower quality life (QoL) adults.Participants included 83 community-dwelling adults. was assessed using a composite the self family-rating scales from Frontal Systems Behavioral Scale (FrSBe). A knowledgeable informant completed Activities Daily Living Questionnaire (ADLQ), participants World Health...
People living with HIV (PLWH) often experience deficits in the strategic/executive aspects of prospective memory (PM) that can interfere instrumental activities daily living. This study used a conceptual replication design to determine whether cognitive intraindividual variability, as measured by dispersion (IIV-dispersion), contributes PM performance and symptoms among PLWH.
Abstract Two experiments were conducted to examine the effects of task importance on event-based prospective memory (PM) in separate samples adults with HIV-associated neurocognitive disorders (HAND) and HIV-infected young substance use (SUD). All participants completed three conditions an ongoing lexical decision task: (1) without PM requirements; (2) requirements that emphasized task; (3) task. In both experiments, all HIV+ groups showed expected increase response costs when task’s was...
Objective: Older adults commonly experience mild declines in everyday functioning and the strategic aspects of prospective memory (PM). This study used multiprocess theory to examine whether demands retrieval cue type (event vs. time based) delay interval length (2 15 min) influence relationship between PM activities daily living (ADLs) older adults. Method: Participants included 97 community-dwelling recruited from Western Australia Participant Pool. were administered Memory for Intentions...
There is a rising prevalence of older HIV+ adults who are at risk deficits in higher order neurocognitive functions and associated problems everyday functioning. The current study applied multiprocess theory to examine the effects HIV aging on measures laboratory-based, naturalistic, self-perceived symptoms prospective memory (PM). Participants included 125 Younger (48 with HIV, age = 32 ± 4.6 years) 189 Older (112 56 4.9 adults. Controlling for global functioning, mood, other demographics,...
As the Covid 19 crisis has revealed, internet is a first-line tool for learning critical health-related information. However, searches are complex and dynamic process that can be fraught with subtleties potential error. The mechanics of searching using electronic health (eHealth) information ostensibly cognitively demanding; yet we know little about role neurocognitive abilities in this regard. Fifty-six young adults completed two naturalistic eHealth search tasks: fact-finding (eHealth...
