ÉVALUATION CLINIQUE DE L 'IMPULSIVITÉ
Bien que l’évaluation du potentiel impulsif d’une personne soit cruciale en neuropsychologie judiciaire, il s’agit d’une tâche difficile pour laquelle peu d’instruments existent. L’impulsivité est un construit multidimensionnel dont les principales composantes nécessitent des instruments de mesure spécifiques. La grande majorité des études et des milieux cliniques utilisent un seul outil (p.ex. mesure d’un état ponctuel) ou des approches mal adaptées aux clientèles psychiatriques ou judiciaires (p.ex. questionnaires auto-rapportés). Le but ici est de proposer au lecteur une définition conceptuelle et opérationnelle de l’impulsivité, ainsi qu’une description exhaustive et critique des instruments de mesures disponibles pour évaluer chacun de ses aspects.
CLINICAVR: CLASSROOM-CPT: A VIRTUAL REALITY TOOL FOR ASSESSING ATTENTION AND INHIBITION IN CHILDREN AND ADOLESCENTS
Having garnered interest both in clinic and research areas, the Virtual Classroom (Rizzo et al., 2000) assesses children's attention in a virtual context. The Digital MediaWorks team (www.dmw.ca) has evolved the original basic classroom concept over a number of iterations to form the ClinicaVR Suite containing the Classroom-CPT as one of its components. The present study has three aims: investigate certain validity and reliability aspects of the tool; examine the relationship between performance in the virtual test and the attendant sense of presence and cybersickness experienced by participants; assess potential effects of gender and age on performance in the test. The study was conducted with 102 children and adolescents from Grade 2 to Grade 10. All participants were enrolled in a regular school program. Results support both concurrent and construct validity as well as temporal stability of ClinicaVR: Classroom-Continuous Performance Test (CPT). Gender exerted no effect on performance, while age did. The test did not cause much cybersickness. We recommend ClinicaVR: Classroom-CPT as an assessment tool for selective and sustained attention, and inhibition, in clinic and research domains.
ASSESSMENT OF EXECUTIVE FUNCTION IN ADOLESCENCE: A COMPARISON OF TRADITIONAL AND VIRTUAL REALITY TOOLS
Paper-pencil type tests are traditionally used in the assessment of executive functions (EF); however, concerns have been raised as to whether these represent actual functioning in everyday life. Virtual reality (VR) environments offer a novel alternative for the assessment of cognitive function and therefore have the potential to enhance the evaluation of EF by presenting individuals with stimuli that come closer to reproducing everyday situations. The aims of this study were to (1) establish which traditional paper-pencil EF tests from the Delis-Kaplan Executive Function System (D-KEFS) are associated with performance on a VR-Stroop task and (2) compare D-KEFS tests and the VR-Stroop task in their ability to predict everyday EF and behavior, as measured by the Behavioral Rating Inventory of Executive Function (BRIEF) and the Child Behavior Checklist (CBCL). Thirty-eight typically developing adolescents aged between 13 and 17 years completed the ClinicaVR: Classroom-Stroop, and five D-KEFS subtests (Trail Making, Tower, Twenty Questions, Verbal Fluency and Color-Word Interference). Their parents completed the BRIEF and CBCL questionnaires. The results indicate that performance on the VR-Stroop task correlates with both traditional forms of EF assessment (D-KEFS, BRIEF). In particular, performance on the VR-Stroop task was closely associated with performance on a paper-pencil inhibition task. Furthermore, VR-Stroop performance more accurately reflected everyday behavioral EF than paper-pencil tasks. VR appears to offer an ecological perspective on everyday functioning and could be seen as complementary to traditional tests in the assessment of complex cognitive abilities.
EXPERIMENTATION OF THREE GUIDANCE METHODS TO SUPPORT THE ACHIEVEMENT OF DAILY ACTIVITIES OF PERSONS WITH INTELLECTUAL DISABILITY
For some people with an intellectual disability (ID), the performance of daily life activities represents a certain number of challenges. Cognitive and adaptive limitations restrict the ability to make choices, solve problems, and evaluate the consequences of taken actions. One of the technological proposals raised by the scientific community is the use of domotics that would give a support that is daily, discreet and responsive to the needs of the person. However, the assistance provided must be personalized to the profile of the person (habits, skills, cognitive difficulties, etc.). The objective of the research is to test three guidance methods in order to determine which are the most appropriate to the cognitive profile of people. This research is conducted with 20 individuals (10 with ID and 10 with borderline ID). A quasi-experimental research design (measuring only after) is used. The independent variable is the type of guidance modalities (audio, photo and video) and the dependent variable is the number of positive responses (efficiency ratio) of the participant in these three different ways. Two appointments are scheduled with each participant. At the first appointment, a neuropsychological evaluation is conducted to assess executive and instrumental functions. In a second phase, the participant experience the guidance methods in the smart apartment of the Université du Québec à Trois-Rivières. The participant must perform two tasks which are to prepare coffee and toast. Assistance is provided in the form of three terms of guidance (audio, photo and video). This guide is offered when a person makes a mistake or misses a crucial step to achieve the task. An observation grid is used to record the participant reactions during the tasks. The results allow us to identify the best guidance methods to support people with an ID in the achievement of daily activities. This information can be used in the development of intervention methods suitable for people with ID.
LONG-WAVE INFRARED FUNCTIONAL BRAIN IMAGING IN HUMAN: A PILOT STUDY
Although some authors suggest to use Long-Wave Infrared (LWIR) sensors to evaluate brain functioning, the link between emissions of LWIR and mental effort is not established. The goal of this pilot study was to determine whether frontal LWIR emissions vary during execution of neuropsychological tasks known to differentially activate the pre-frontal cortex (simple color presentations, induction of the Stroop effect, and a gambling task with real money). Surprisingly, LWIR emissions as measured with bilateral frontal sensors in 47 participants significantly differed between tasks, in the supposed direction (Color<Stroop<Gambling), in spite of counterbalanced presentations. This pilot study suggests that investigations of convergent validity with other types of brain imaging techniques can be initiated with LWIR imaging. If confirmed, this technique would offer a simple and accessible method to evaluate frontal cortex activation.
DEVELOPMENT AND INITIAL ASSESSMENT OF A NEW PARADIGM FOR ASSESSING COGNITIVE AND MOTOR INHIBITION: THE BIMODAL VIRTUAL-REALITY STROOP
Assessing and predicting inhibition in adults is a common assignment for clinicians. However, there is no single measure of inhibition that is complete, sensitive and enjoyable. The main goal of this study was to develop a virtual reality neuropsychological task (the bimodal VR-Stroop) capable of measuring both cognitive (control of internal and external interference) and motor inhibition (a go no-go paradigm with reaction time variation, commission errors and omissions). Preliminary data obtained with 71 healthy adult participants confirmed that the VR-Stroop is capable of eliciting the Stroop effect with bimodal stimuli. Initial validation data also suggested that measures of the VR-Stroop significantly correlate with measures of the Elevator counting with distracters, the Continuous Performance Task (CPT-II), and the Stop-it task. Finally, regression analyses indicated that commission errors and variability of reaction times at the VR-Stroop were significantly predicted by scores of the Elevator task and the CPT-II. These preliminary results suggest that the VR-Stroop is an interesting measure of cognitive and motor inhibition for adults, although confirmatory investigations are warranted.
VIRTUAL REALITY AS A SCREENING TOOL FOR SPORTS CONCUSSION IN ADOLESCENTS
There is controversy surrounding the cognitive effects of sports concussion. This study aimed to verify whether the technique of virtual reality could aid in the identification of attention and inhibition deficits in adolescents. A prospective design was used to assess 25 sports-concussed and 25 non-sports-concussed adolescents enrolled in a sport and education programme. Participants were evaluated in immersive virtual reality via ClinicaVR: Classroom-CPT and in real life
via the traditional VIGIL-CPT. The neuropsychological assessment using virtual reality showed greater sensitivity to the subtle effects of sports concussion compared to the traditional test, which showed no difference between groups. The results also demonstrated that the sports concussion group reported more symptoms of cybersickness and more intense cybersickness than the control group. Sports concussion was associated with subtle deficits in attention and inhibition. However, further studies are needed to support these results.
MULTITASKING AND PROSPECTIVE MEMORY: CAN VIRTUAL REALITY BE USEFUL FOR DIAGNOSIS?
Prospective memory (PM) is defined as the ability to perform an intended action in the future. It is with this type of memory that one can observe the high- est number of memory errors made within the context of everyday life. Furthermore, researchers have demonstrated that prospective memory is extremely sensitive to traumatic brain injury (TBI). In the past few years, research in the field of PM has shown how the frontal lobes are involved in the context of multitasking. Multitasking is defined by the ability to execute and monitor a set of “goal-oriented” behaviours in order to realize planned actions. Shallice and Burgess have discussed the importance of multitasking as an essential component of prospective memory. During the last few years, neuropsychological tests have been criticized, especially with regard to everyday functioning. At present, neuropsychological tools sometimes fail to detect subtle and complex deficits in the goal-oriented behaviours in order to realise self- planned actions. We now seem to have at our disposal virtual reality (VR) to compensate for the different limits of traditional assessment. One of the major plusses of VR is its capacity to bring the real world into a laboratory setting thus permitting the control of stimuli and the recording of the patient’s answers and behaviours. Over time, some experiments which have used VR technology have demonstrated its ecological validity and its capacity to detect planning or prospective memory deficit. The objective of the present study is to demonstrate the capacity of VR to detect prospective memory problems.
RECOGNITION OF EMOTION IN MALTREATED CHILDREN LIVING IN INTENSE STRESS CONTEXT
The purpose of this research was to study emotion recognition in maltreated children from ve to se- ven years of age, with the Affect Recognition subtest from the NEPSY-II. The group was composed of 22 boys and 12 girls all receiving child protective care services. Results show that boys had signi cantly lower scores, when compared with girls and with the test’s norms. Also, IQ didn’t in uence children’s per- formances. Results are explained by the negative impacts of intense stress on the development of socio- emotional abilities.
