Virtual reality technology in neuropsychological testing: A systematic review

Neuropsychological testing aims to measure individuals' cognitive abilities (e.g. memory, attention), analysing their performance on specific behavioural tasks. Most neuropsychological tests are administered in the so-called ‘paper-and-pencil’ modality or via computerised protocols. The adequacy of these procedures has been recently questioned, with more specific concerns about their ecological validity, i.e. the relation between test scores observed in the laboratory setting and the actual everyday cognitive functioning. In developing more ecological tasks, researchers started to implement virtual reality (VR) technology as an administration technique focused on exposing individuals to simulated but realistic stimuli and environments, maintaining at the same time a controlled laboratory setting and collecting advanced measures of cognitive functioning. This systematic review aims to present how VR procedures for neuropsychological testing have been implemented in the last years. We initially explain the rationale for supporting VR as an advanced assessment tool, but we also discuss the challenges and risks that can limit the widespread implementation of this technology. Then, we systematised the large body of studies adopting VR for neuropsychological testing, describing the VR tools' distribution amongst different cognitive functions through a PRISMA-guided systematic review. The systematic review highlighted that only very few instruments are ready for clinical use, reporting psychometric proprieties (e.g. validity) and providing normative data. Most of the tools still need to be standardised on large cohorts of participants, having published only limited data on small samples up to now. Finally, we discussed the possible future directions of the VR neuropsychological test development linked to technological advances.     

Validation of the Chinese version of the Walsh Family Resilience Questionnaire

The Walsh Family Resilience Questionnaire (WFRQ) is one of the most widely used and strong theory-based measurement tools of family resilience. This study aimed to develop and psychometrically test the Chinese version of the WFRQ (WFRQ-C). The WFRQ was translated following Brislin's translation model. Psychometric testing, combining classical theory test and item response theory, was conducted with a sample of 800 community adult residents. The Connor-Davidson resilience scale-10 (CD-RISC-10), Self-reported Family Happiness Scale (SFHS-1), and Family APGAR (Adaption, Partnership, Growth, Affection, Resolve) Scale (Family APGAR-5) were applied for convergent validity. Six items were deleted at the item analysis level. The minimum average partial test and a parallel analysis supported a three-factor structure, which was validated by confirmatory factor analysis. The three factors were named “Family belief system,” “Organization, communication and problem solving,” and “Utilization of external resources.” The WFRQ-C was significantly correlated with CD-RISC-10, SFHS-1, and Family APGAR-5, with r values ranged from 0.51 to 0.56. The Cronbach's α was 0.97 for the scale and 0.93, 0.95, and 0.72 for the three factors, respectively. The ICCs of 0.96 for the whole scale, and 0.95, 0.75, and 0.95 for the three factors, respectively. The mean score for the WFRQ-C was 97.00 ± 17.94, of which per capita monthly income and education level were predictors. The 26-item WFRQ-C is a stable, concise, and validated tool to measure family resilience. It is applicable for Chinese community adults in nonspecific stressful settings and has potential utility in the health care domain.     

Période périnatale et Rorschach : normes,indicateurs, mentalisation et perspectives théorico-cliniques

ObjectiveThe perinatal period is a maturation phase characterised by the appearance of a radical psychological and identity crisis, little studied by projective methods, in particular the Rorschach inkblot test. The objective of this article is to offer a list of Rorschach norms and indicators adapted to the perinatal population. This is to comprehend the psychological modifications occurring during pregnancy.Materials and methodThe projective Rorschach inkblot test was presented to a representative sample of 54 pregnant primiparous French women. Based on the scoring and analysis methods of the Parisian School, the quantitative norms from the analysis of the psychogram, the chosen cards, and the mentalization indicators were compared to those of the general population.ResultsWith the exception of F +% and H%, all the normative data for the perinatal population are significantly different from those related to the general population (p .005). On a qualitative level, the interpretation of the data highlights the presence of major inhibition mechanisms, associated with a preconscious functioning stasis.ConclusionThe normative data in Rorschach of the perinatal population should be specifically used for the study and psychological support devoted to this population. It also allows a better understanding of the feminine psychologic modifications during pregnancy.     

Définir ou détecter des pathologies ? Utilisation et interprétation des scores seuils à la lumière du débat dimensions/catégories

A number of psychometric tests are aimed at locating the performance of an individual along a continuous range that goes from normal to worrying. In a different paradigm, there are tests whose goal is to assess whether or not an individual is healthy with respect to a psychological, psychiatric or neurological pathology that is defined independently from the test itself. The former rely on a dimensional concept of psychopathologies; the latter imply a categorical concept. The former require to compare the performance of the individual to a standard sample that is representative of the general population; the latter involve a standard sample representative of the healthy population only. The former might imply the use of a cut-off score to indicate that a certain degree of rarity of the performance has been reached, while the latter must involve a cut-off score to make a decision (whether the individual belongs to the “healthy” or “pathological” category), a score that is most often set so as to control the false-positive rate in making this decision. In the former paradigm, the cut-off score defines or contributes to define the pathology. In the latter, it only helps detecting it. This article aims at making clear the difference between these two realms and highlight their practical as well as theoretical impact on psychological practice.     

Reduction of faking with the use of a forced-choice personality test: Cross-cultural comparisons between South Korea and the United States

Forced-choice format tests have been suggested as an alternative to Likert-scale measures for personnel selection due to robustness to faking and response styles. This study compared degrees of faking occurring in Likert-scale and forced-choice five-factor personality tests between South Korea and the United States. Also, it was examined whether the forced-choice format was effective at reducing faking in both countries. Data were collected from 396 incumbents participating in both honest and applicant conditions (N_SK = 179, N_US = 217). Cohen's d values for within-subjects designs (ds_within) for between the two conditions were utilized to measure magnitudes of faking occurring in each format and country. In both countries, the degrees of faking occurring in the Likert-scale were larger than those from the forced-choice format, and the magnitudes of faking across five personality traits were larger in South Korea by from 0.07 to 0.12 in ds_within. The forced-choice format appeared to successfully reduce faking for both countries as the average ds_within decreased by 0.06 in both countries. However, the patterns of faking occurring in the forced-choice format varied between the two countries. In South Korea, degrees of faking in Openness and Conscientiousness increased, whereas those in Extraversion and Agreeableness were substantially decreased. Potential factors leading to trait-specific faking under the forced-choice format were discussed in relation to cultural influence on the perception of personality traits and score estimation in Thurstonian item response theory (IRT) models. Finally, the adverse impact of using forced-choice formats on multicultural selection settings was elaborated.     

Revisiting the effect of incentivization on cognitive reflection: A meta-analysis

The effect of performance-based incentives on judgment biases is a controversial issue. A recent extensive meta-analysis of Brañas-Garza et al. (2019, https://doi.org/10.1016/j.socec.2019.101455 ) found no effect of incentives on performance in the cognitive reflection test (CRT), a test commonly used for assessing heuristic versus deliberative judgments. We conducted a meta-analysis of studies that directly compared an incentive versus no-incentive conditions (n = 2836) and found a small positive effect of incentivization (Cohen's d = .21) on CRT performance. In addition, we re-examined the Brañas-Garza et al. (2019) dataset (n = 39,385), taking into consideration not only whether incentivization was used but also the nominal and fiscal size of the incentive. The results show that surprisingly when including only studies that used monetary incentives, the effect of incentivization and incentive size are significant, even when taking into consideration other aspects of the studies. The results thus suggest a small but robust effect of incentives on judgment biases.     

跨期选择单维占优模型的过程检验

跨期选择需要决策者在眼前与未来的损益之间做出权衡与取舍。主流跨期选择理论认为, 跨期选择是把未来价值折扣到现在, 根据折扣后的价值进行选择的过程; 而单维占优模型则认为决策者把“结果”维度上的差异和“延迟”维度上的差异进行比较(维度间差异比较), 然后根据差异更大的维度(即占优势的维度)进行决策。跨期选择众理论之争无果的原因之一或是研究者未能找到揭示其心理过程的令人信服的证据。为此, 本研究采用过程检验而非结果拟合的方法, 首创了“直观模拟天平”任务, 对维度间差异比较的大小进行测量, 从而为验证单维占优模型提供了支持性的证据。实验1A证明了维度间差异大小中介了选择结果, 被试认为“结果”维度上的差异相对于“延迟”维度上的差异越大, 越倾向于选择延迟长、结果大的选项; 反之, 被试认为“延迟”维度上的差异相对于“结果”维度上的差异越大, 越倾向于选择延迟短、结果小的选项。实验1B证明了维度间差异比较是在选择时实时(而不是在选择后)进行的。实验1C通过调整实验程序消减了共同方法偏差对结果的影响。实验2进一步证明维度间差异比较可以解释众多的跨期选择异象。通过4个实验, 本研究揭示了维度间差异比较构成了跨期选择的重要(尽管可能不是唯一)决策过程, 为支持单维占优模型提供了重要的过程验证证据。     

应激对风险和社会决策的影响

应激是有机体在受到真实或者潜在的威胁刺激时所表现出来的全身性非特异性反应, 伴随着紧张和焦虑的心理体验, 交感神经系统的兴奋, 糖皮质激素分泌的增多以及脑干−边缘系统−前额叶神经环路的改变。应激对个体在风险决策行为中的风险寻求和风险回避倾向, 社会决策行为中的利己和利他倾向都会产生重要影响。策略使用异常、习惯化和自动化反应增强、反馈学习过程以及奖惩敏感性的改变是应激影响决策行为的认知基础; 应激激素的分泌, 及杏仁核、前额叶等在决策过程发挥重要作用的脑区活动的改变则为应激作用于决策行为的神经基础。未来研究应重点关注：应激的个体差异与应激对决策影响效应多样性的关系; 综合多种指标对应激进行测量; 考察应激的时序效应; 揭示个体的最佳应激水平; 加强对慢性应激影响决策以及应激对决策影响效应可逆性的研究; 揭示应激影响决策的神经机制。     

辛苦所得与意外所得的非理性消费偏差：基于IAT检测和ERP证据

不同来源的财富因其在人们心理的权重差异会导致对其消费态度与方式的不同。前人运用一系列行为实验已发现意外所得更容易消费、辛苦所得则不容易消费。基于心理账户和内隐社会认知等理论, 运用IAT和ERP考察财富的意外所得与辛苦所得在人们心理引起的内在消费偏差, 进而对内隐消费态度和脑加工机制进行间接检测。IAT研究结果表明, 意外所得与容易消费的联结更加紧密, 辛苦所得与不易消费的联结更加紧密, 从内隐层面验证了前人的行为研究结论; ERP研究结果发现辛苦所得与意外所得这两个不同收入来源可能建立了不同脑加工机制, 且在P3和LPC成分得到反映, P3成分可能是反映辛苦所得组偏好难消费型消费方式的ERP成分, LPC反映了意外所得收入条件下个体偏好易消费型消费方式的特点。
