Multitasking in the military: Cognitive consequences and potential solutions

Multitasking—the performance of several tasks at the same time—is becoming increasingly prevalent in workplaces. Multitasking is known to disrupt performance, particularly in complex and dynamic situations, which is exactly what most military occupations entail. Because military errors can be consequential, the detrimental impact of multitasking on cognitive functioning in such contexts should be taken seriously. This review pertains to high‐consequence military occupations that require strong multitasking skills. More specifically, it highlights cognitive challenges arising from different forms of multitasking and discusses their underlying cognitive processes. Because such challenges are not expected to diminish, this review proposes context‐relevant solutions to decrease occupational workload, either by reducing the cognitive load ensuing from the to‐be‐performed tasks or by improving soldiers' multitasking abilities. To ensure effective implementation of these solutions, we stress the need to design context‐adapted tools and procedures, and to guide human resource managers in developing particular strategies.     

Digging beneath the surface: Results from stage one of a qualitative analysis of factors influencing the well-being of trans youth in Quebec

ABSTRACT

Background: The literature on trans youth has been dominated by etiological studies interested in trans experience as a medical phenomenon. An emerging body of literature has begun to document that trans youth are a diverse, vulnerable, yet resilient population, and to investigate the role of various sites of support such as the family, peer groups, institutions, and community spaces in contributing to or impeding trans youth's well-being.

Method: This article presents the results of Stage One of interviews (n = 24) conducted for a Community-Based Participatory Action Research (CBPAR) qualitative research project based in Quebec. It studies the factors that enhance trans youth's well-being as well as the factors of oppression that negatively affect it. This paper offers a brief overview of the anti-oppressive methodology used for this project, emphasizing how CBPAR was combined with Grounded Theory (GT) methods to encourage the direct involvement of communities and the translation of knowledge into action.

Results: We present preliminary categories emerging through the ongoing axial coding process. These categories address trans youth's experiences in and perceptions of various “sites”: 1) healthcare services both for gender-related and general care, 2) other institutional spaces, 3) the family and other social circles, and 4) community spaces.

Conclusion: While much of this study's results support existing evidence on trans youth's experiences, they also provide a more nuanced portrayal of the complex ways in which recognition, as well as non-, mis-, or mal-recognition, influence trans youth's well-being at different sites. We also argue that recognition itself must be considered through the lens of intersectionality.     

Procura-PALavras (P-PAL): A Web-based interface for a new European Portuguese lexical database

In this article, we present Procura-PALavras (P-PAL), a Web-based interface for a new European Portuguese (EP) lexical database. Based on a contemporary printed corpus of over 227 million words, P-PAL provides a broad range of word attributes and statistics, including several measures of word frequency (e.g., raw counts, per-million word frequency, logarithmic Zipf scale), morpho-syntactic information (e.g., parts of speech [PoSs], grammatical gender and number, dominant PoS, and frequency and relative frequency of the dominant PoS), as well as several lexical and sublexical orthographic (e.g., number of letters; consonant–vowel orthographic structure; density and frequency of orthographic neighbors; orthographic Levenshtein distance; orthographic uniqueness point; orthographic syllabification; and trigram, bigram, and letter type and token frequencies), and phonological measures (e.g., pronunciation, number of phonemes, stress, density and frequency of phonological neighbors, transposed and phonographic neighbors, syllabification, and biphone and phone type and token frequencies) for ~53,000 lemmatized and ~208,000 nonlemmatized EP word forms. To obtain these metrics, researchers can choose between two word queries in the application: (i) analyze words previously selected for specific attributes and/or lexical and sublexical characteristics, or (ii) generate word lists that meet word requirements defined by the user in the menu of analyses. For the measures it provides and the flexibility it allows, P-PAL will be a key resource to support research in all cognitive areas that use EP verbal stimuli. P-PAL is freely available at http://p-pal.di.uminho.pt/tools.     

Tool use in neurodegenerative diseases: Planning or technical reasoning?

Recent works showed that tool use can be impaired in stroke patients because of either planning or technical reasoning deficits, but these two hypotheses have not yet been compared in the field of neurodegenerative diseases. The aim of this study was to address the relationships between real tool use, mechanical problem‐solving, and planning skills in patients with Alzheimer's disease (AD, n = 32), semantic dementia (SD, n = 16), and corticobasal syndrome (CBS, n = 9). Patients were asked to select and use ten common tools, to solve three mechanical problems, and to complete the Tower of London test. Motor function and episodic memory were controlled using the Purdue Pegboard Test and the BEC96 questionnaire, respectively. A data‐transformation method was applied to avoid ceiling effects, and single‐case analysis was performed based on raw scores and completion time. All groups demonstrated either impaired or slowed tool use. Planning deficits were found only in the AD group. Mechanical problem‐solving deficits were observed only in the AD and CBS groups. Performance in the Tower of London test was the best predictor of tool use skills in the AD group, suggesting these patients had general rather than mechanical problem‐solving deficits. Episodic memory seemed to play little role in performance. Motor dysfunction tended to be associated with tool use skills in CBS patients, while tool use disorders are interpreted as a consequence of the semantic loss in SD in line with previous works. These findings may encourage caregivers to set up disease‐centred interventions.     

Can pupillometry index auditory attentional capture in contexts of active visual processing?

The rare presentation of a sound that deviates from the auditory background tends to capture attention, which is known to impede cognitive functioning. Such disruption is usually measured using performance on a concurrent visual task. Growing evidence recently showed that the pupillary dilation response (PDR) could index the attentional response triggered by a deviant sound. Given that the pupil diameter is sensitive to several vision-related factors, it is unclear whether the PDR could serve to study attentional capture in such contexts. Hence, the present study aimed at verifying whether the PDR can be used as a proxy for auditory attentional capture while a visual serial recall task (Experiment 1) or a reading comprehension task (Experiment 2) – respectively producing changes in luminance and gaze position – is being performed. Results showed that presenting a deviant sound within steady-state standard sounds elicited larger PDRs than a standard sound. Moreover, the magnitude of these PDRs was positively related to the amount of performance disruption produced by deviant sounds in Experiment 1. Performance remained unaffected by the deviants in Experiment 2, thereby implying that the PDR may be a more sensitive attention-capture index than behavioural measures. These results suggest that the PDR can be used to assess attentional capture by a deviant sound in contexts where the pupil diameter can be modulated by the visual environment.     

Exploring the Relationship Between Child Maltreatment,Intimate Partner Violence Victimization,and Self-Injurious Thoughts and Behaviors

Child maltreatment is considered a significant risk factor for young adult self-injury; however, the mechanisms that underlie this relationship are not yet understood. To elucidate this association, the mediating role of intimate partner violence victimization in the relationship between child maltreatment and self-injurious thoughts and behaviors was investigated. The sample consisted of 406 young adults (346 females; M_age = 19.87 years; SD = 1.72) involved in a couple relationship. Results of bootstrapping procedures demonstrated that intimate partner violence victimization mediated the relationship between child maltreatment and self-injurious behaviors but did not mediate the association between child maltreatment and self-injurious thoughts. Results suggest that young adults with a history of child maltreatment may be more likely to be exposed to IPV victimization, which, in turn, is associated with the use of self-injurious behaviors, but not the use of self-injurious thoughts. Findings highlight the utility of examining models that incorporate distal and proximal factors contributing to self-injury, and provide direction toward better understanding the relationship experiences of self-injuring young adults.     

Activated or deactivated? Understanding how cognitive appraisals can drive emotional activation in the aftermath of daily work events

Introduction

Past research has highlighted the relevance of cognitive appraisals in the link events-emotions (e.g., appraisal of an event's importance and its pleasant or unpleasant valence). We hypothesized a 3-way interaction between affective events (hassles and uplifts), cognitive appraisals of importance and intrinsic pleasantness on emotional activation.

Dimensions of Acculturation and Work Hope in International Students

Work hope is an emerging and important factor in the career development process of international students. In this study, the authors focused on the work hope of international students and examined its relation to dimensions of acculturation (i.e., dominant society immersion, ethnic identity, ethnic society immersion, individualism, and collectivism). A total of 340 international students completed an online survey. Results of a correlation analysis revealed associations in the expected directions. Multivariate regression analysis revealed that horizontal collectivism, horizontal individualism, and vertical collectivism had a significant and unique contribution in explaining work hope. Implications and recommendations for future research are discussed.
