Objective
The objective of the present study was to examine the neurocognitive profiles associated with limited English proficiency (LEP).
Method
A brief neuropsychological battery including measures with high (HVM) and low verbal mediation (LVM) was administered to 80 university students: 40 native speakers of English (NSEs) and 40 with LEP.
Res...
Background: Abbreviated neurocognitive tests offer a practical alternative to full-length versions but often lack clear interpretive guidelines, thereby limiting their clinical utility.
Objective: To replicate validity cutoffs for the Boston Naming Test —Short Form (BNT–15) and to introduce a clinical classification system for the BNT–15 as a measu...
Objective
This project was designed to cross-validate existing performance validity cutoffs embedded within measures of verbal fluency (FAS and animals) and develop new ones for the Emotion Word Fluency Test (EWFT), a novel measure of category fluency.
Method
The classification accuracy of the verbal fluency tests was examined in two samples (70 c...
This study was designed to provide initial empirical validation for the Five-Variable Psychiatric Screener (V-5), a five-variable (energy, depression, anxiety, pain, and fatigue) psychiatric screener based on the visual analog scaling method. The V-5 was administered twice (at the beginning and end of a neuropsychological battery) to 102 clinically...
This study was designed to introduce and validate a forced choice recognition trial to the Rey Complex Figure Test (FCR RCFT ). Healthy undergraduate students at a midsized Canadian university were randomly assigned to the control (n = 80) or experimental malingering (n = 60) conditions. All participants were administered a brief battery of neurops...
Objective: This study was designed to cross-validate previously published performance validity cutoffs embedded within the Complex Ideational Material (CIM) and the Boston Naming Test–Short Form (BNT–15).
Method: Seventy healthy undergraduate students were randomly assigned to either a control condition (n = 40) and instructed to perform to the bes...
Objective: To determine cognitive outcomes in older adults (≥ 50 years old) having sustained a traumatic brain injury (TBI) using meta-analysis.
Methods: MedLine and PsycInfo databases were searched to identify studies comparing neuropsychological profiles in older adults with and without a history of TBI across various injury severities and times...
Objective:
This study compared failure rates on performance validity tests (PVTs) across liberal and conservative cutoffs in a sample of undergraduate students participating in academic research.
Method:
Participants (n = 120) were administered four free-standing PVTs (Test of Memory Malingering, Word Memory Test, Rey 15-Item Test, Hiscock Force...
Poor effort by examinees during neuropsychological testing has a profound effect on test performance. Although neuropsychological experiments often utilize healthy undergraduate students, the test-taking effort of this population has not been investigated previously. The purpose of the present study was to determine whether undergraduate students e...
