Cognitive Failures: Relationship with Perceived Emotions, Stress, and Resting Vagally-Mediated Heart Rate Variability

Cognitive failures represent everyday task failures that individuals are normally capable of completing. While cognitive failures measured with the Cognitive Failures Questionnaire can be considered a trait, the psychophysiological states associated with cognitive failures are yet to be fully understood. The aim of this paper was to investigate the extent to which the perception of experiencing cognitive failures in daily life is associated with both psychological (i.e., perceived emotional valence, emotional intensity, and stress), as well as physiological (i.e., vagally-mediated heart rate variability, vmHRV) variables. A total of 69 participants were involved in this study (47 male, 22 female; Mage = 22.4 years). Participants underwent a 5-min heart rate variability measurement and filled out the self-report psychological variables, before completing the Cognitive Failures Questionnaire, providing scores for Distractibility, Forgetfulness, and False Triggering. When combining the predictors together into a hierarchical regression analysis, only the model related to the Distractibility subscale was found to be significant (unique significant negative predictor: resting vmHRV). Further research should investigate whether influencing resting vmHRV, with interventions such as slow-paced breathing, may decrease the perception of cognitive failures related to distractibility.

SmartPrompt Reminder Application Improves Everyday Task Completion and Reduces Inefficient Behaviors

The SmartPrompt phone-based reminder application was designed according to neuropsychological theory and pilot testing to facilitate everyday functioning. A laboratory-based pilot of ten participants with MCI and mild dementia showed significantly greater task completion with significantly fewer checking behaviors when using the SmartPrompt versus a control condition. Younger individuals and those who engaged in more checking behaviors completed more tasks in the control condition, but these relations were not significant when using the SmartPrompt. After 15 minutes of training, caregivers achieved near perfect scores on a SmartPrompt configuration quiz. Participant and caregiver usability ratings were strong, even though participants reported relatively low computer proficiency and neutral/unfavorable attitudes towards technology. Piloting informed modifications of the SmartPrompt to enhance personalization (e.g., customized alarms/rewards) and improved human-computer-interaction for in-home testing. Preliminary in-home test data on individually-owned smartphones and conclusions regarding barriers and facilitators to the effectiveness of the modified SmartPrompt will be discussed.

Automatic Billing Cart

Shopping malls are a much more convenient place where people buy products of daily necessity. On holidays, a lot of rush can be seen in shopping malls and it becomes a very tedious task to get the billing done. In cosmopolitan cities, to shop at supermarkets and shopping markets an everyday task. Everyone of us has encountered long queues for the payment of the bill at shopping centers during holidays and weekends, the rush increase seven more at the time of festive seasons because of the discounts and product offers. Customers pick the products they want to buy and put them into their shopping carts. After customers have picked the products, they need to get the billing done. For the payment of the bill, they have to move to billing counter. At the billing counter the cashier, scans the products using a barcode scanner and then produces the bill. This is a manually operated process and hence, time consuming. Therefore, it leads to the long queues at billing counters. This paper proposes a way to develop a brilliant shopping cart system that will monitor the purchased products and help produce the bill in a less time-consuming way. This paper looks forward to solving the problem of rush at billing counter using a barcode scanner and RF transceiver that sends and receives the data.

Anxious Breath

This article is a theoretical, audiovisual, and personal exploration of being a trans and non-binary person and the challenges this position produces at the moment of entering the outside world. Getting ready to enter public space is a seemingly mundane everyday task. However, in the context of a world that continuously fails or refuses to recognize trans and non-binary people, the literal act of stepping outside can mean to move from a figurative state of self-determination to one of imposition. We produced a short film project called Step Out to delve into issues of vulnerability and recognition that surface throughout experiences of crossing the threshold into public space. It explores the acts performed as preparation to face the world, and invokes the emotions this can conquer in trans and non-binary people. Breathing is the leading metaphor in the film, indicating existence and resistance simultaneously. The article concludes with a discussion of affective states and considers them, along with failed recognition, through the lens of Lauren Berlant’s concept of “cruel optimism.”

Abstract sequential task control is facilitated by practice and embedded motor sequences

Everyday task sequences, such as cooking, contain overarching goals (completing the meal), sub-goals (prepare vegetables), and motor actions (chopping). Such tasks generally are considered hierarchical because superordinate levels (e.g., goals) affect performance at subordinate levels (e.g., sub-goals and motor actions). However, there is debate as to whether this hierarchy is “strict” with unidirectional, top-down influences, and it is unknown if and how practice affects performance at the superordinate levels. To investigate these questions, we manipulated practice with sequences at the goal and motor action levels using an abstract, or non-motor, task sequence paradigm (Desrochers et al., 2015; Schneider & Logan, 2006). In three experiments, participants performed memorized abstract task sequences composed of simple tasks (e.g., color/shape judgements), where some contained embedded motor response sequences. We found that practice facilitated performance and reduced control costs for abstract task sequences and subordinate tasks. The interrelation was different between the hierarchical levels, demonstrating a strict relationship between abstract task sequence goals and sub-goals and a non-strict relationship between sub-goal and motor response levels. Under some conditions, the motor response level influenced the abstract task sequence level in a non-strict manner. Further, manipulating the presence or absence of a motor sequence after learning indicated that these effects were not the result of an integrated representation produced by practice. These experiments provide evidence for a mixed hierarchical model of task sequences and insight into the distinct roles of practice and motor processing in efficiently executing task sequences in daily life.

‘Normal’ hearing thresholds and fundamental auditory grouping processes predict difficulties with speech-in-noise perception

Understanding speech when background noise is present is a critical everyday task that varies widely among people. A key challenge is to understand why some people struggle with speech-in-noise perception, despite having clinically normal hearing. Here, we developed new figure-ground tests that require participants to extract a coherent tone pattern from a stochastic background of tones. These tests dissociated variability in speech-in-noise perception related to mechanisms for detecting static (same-frequency) patterns and those for tracking patterns that change frequency over time. In addition, elevated hearing thresholds that are widely considered to be ‘normal’ explained significant variance in speech-in-noise perception, independent of figure-ground perception. Overall, our results demonstrate that successful speech-in-noise perception is related to audiometric thresholds, fundamental grouping of static acoustic patterns, and tracking of acoustic sources that change in frequency. Crucially, speech-in-noise deficits are better assessed by measuring central (grouping) processes alongside audiometric thresholds.

Embodiment in Virtual Environments: The Role of Working Memory in Experiencing Presence as Revealed via Eye Tracking

Working memory capacity (WMC) is critical in maintaining goal-directed behavior and in inhibiting task irrelevant or conflicting thoughts. Using eye tracking data, the current study developed measures to investigate users' experiences of presence. We investigated the cognitive processing mechanisms of feelings of presence by examining how users of varying WMC coordinate their attention between their actions in using external controllers for computer mediated environments, and the actions produced by their avatars in virtual environments. To rule out the possibility of participants acting out of social pressure, a well-practiced everyday task with minimal social component was used. Participants performed vegetable cutting tasks in a desktop virtual environment by controlling an avatar's arm, with no pressure (Experiment 1) versus while pressured to improve the evenness of their cuts (Experiment 2). The results showed that high WMC participants experienced higher degrees of presence, as indicated by the attention allocated to the avatar's hand and to task planning. Under performance pressure, low WMC participants became more immersed in the tasks. The mechanisms of adaptive and personalized presence in virtual world simulation training environments are discussed in light of our findings on the effects of pressure and individual differences of WMC in experiencing presence.

The Sacropolitics of Labor Conscription

This chapter analyzes the authorities’ mounting difficulties in conscripting the population for public works—a second “routine” activity they had previously undertaken with great success. The chapter shows the delusional nature of government plans, and how delusion was represented as rationality and routine. The chapter also explores officials’ confusion about their inability to carry out the ordinary, everyday task of conscription, and their sense that what had formerly seemed ordinary was anything but that. Chapter Eight also examines the explanations that government officials generated to explain their inability to carry out activities that had formerly been routine—in which their attribute their difficulties to a series of phantom figures that are said to haunt government efforts to rule.

Indirect pathway from caudate tail mediates rejection of bad objects in periphery

The essential everyday task of making appropriate choices is a process controlled mainly by the basal ganglia. To this end, subjects need not only to find “good” objects in their environment but also to reject “bad” objects. To reveal this rejection mechanism, we created a sequential saccade choice task for monkeys and studied the role of the indirect pathway from the CDt (tail of the caudate nucleus) mediated by cvGPe (caudal-ventral globus pallidus externus). Neurons in cvGPe were typically inhibited by the appearance of bad objects; however, this inhibition was reduced on trials when the monkeys made undesired saccades to the bad objects. Moreover, disrupting the inhibitory influence of CDt on cvGPe by local injection of bicuculline (GABAA receptor antagonist) impaired the monkeys’ ability to suppress saccades to bad objects. Thus, the indirect pathway mediates the rejection of bad choices, a crucial component of goal-directed behavior.
