Cognitive Failures and the Role of Emotion in Dimensional Schizotypy: A Replication and Extension

Introduction: Cognitive failures are commonplace within the general population but may be particularly heightened in those with higher levels of schizotypy. This is especially salient in the context of enduring trait and momentary state negative emotion which often contributes to increases in daily impairments, leading to a more debilitating and distracted life. Particularly, individuals with elevated levels of schizotypy may be more likely to experience cognitive failures, especially in the presence of negative trait emotion such as depression, anxiety, and stress. However, little is known about the influence of state emotion and the distinct roles that state and trait emotion may have with cognitive failures and schizotypy. Methods: To replicate and extend previous findings, 306 (58% males) undergraduate students aged 18–50 years (M = 19.343; SD = 2.493) completed self-report measures of cognitive failures, trait and state emotion, and schizotypy. Mediation and moderation analyses were performed in SPSS to examine the potential effects of trait and state emotion on the relationship between schizotypy and cognitive failures. Results: Consistent with previous findings, mood symptomology, in addition to negative affect, mediated cognitive failures in those with higher levels of schizotypy. However, in our sample, positive affect did not appear to buffer against cognitive failures. Conclusion: The findings of the present study suggest there may be a nuanced relationship between both negative trait and state emotions on the relationships between cognitive failures and schizotypy. Understanding the interaction of enduring versus momentary emotion on cognition as they relate to an elevated risk for developing schizophrenia-spectrum phenomena may be a point for earlier and more targeted interventions.

The context matters - not all prolonged sitting bouts are equally related to momentary affective states: an ambulatory assessment with sedentary-triggered E-diaries

BackgroundSedentary behaviors (SB) and especially prolonged sitting bouts are highly prevalent in daily life and studies indicated an association with an increased risk for several non-communicable diseases. Consequently, guidelines to reduce SB were developed. At the same time, an in-depth knowledge regarding SB such as where, what and with whom people spend time sedentary as well as correlates such as affective states of prolonged sitting bouts, is still lacking. A more differentiated view on SB is necessary to identify detrimental and modifiable sedentary bouts. We addressed this gap by conducting an ambulatory assessment study including accelerometer and sedentary-triggered e-diaries that captures data during prolonged sitting bouts (> 20 min). We investigated how contextual factors of prolonged sitting bouts are associated with momentary affective states.MethodFour studies were combined with a final sample of 308 participants (50.3% female, Mage, 27.4, range, 17–66). SB was assessed objectively with thigh-worn accelerometers for four to five days. Whenever a participant was sitting for 20 or 30 min the accelerometer triggered questions assessing social (not alone vs. alone) and environmental (leisure vs. working) factors as well as momentary affective states (valence, energetic arousal and calmness). Multilevel analyses were used to examine within-person associations between different contexts and mood during prolonged sitting.ResultsMomentary affective states varied significantly due to different social and environmental contexts (ps < 0.001): Sitting together with others was associated with higher levels of valence and energetic arousal. Furthermore, sitting during leisure time was associated with higher levels of valence and calmness and lower levels of energetic arousal. Significant interaction analyses revealed that participants had the highest ratings while sitting during leisure episodes together with others.ConclusionFindings showed that prolonged sitting bouts differ regarding their association with affect. Sitting with others, sitting during leisure time and especially sitting during leisure time and with others, was associated with higher levels of momentary affective states, respectively. Thus, SB guidelines should focus on reducing those SB episodes that are associated with lower levels of affect, for example during working episodes.

What difference a day makes: An examination of dynamic antecedents of voice

Research has mostly considered employee voice to be a relatively stable behavior and has examined it primarily on a between-person level. In this work, we reason that existing between-person examinations of voice behavior should be complemented with more within-person assessments. Integrating regulatory focus theory with affective events theory, we hypothesize an affective events model of employee voice. To understand whether and to what extent increases and decreases in job resources and momentary states in relation to the prior day affect voice behavior, we conducted a diary study and use multilevel analysis to analyze the hypotheses in a cross-level moderated mediation model. Results confirm that voice varies within individuals and that, on an intrapersonal level, an increase in job situations increases voice behavior via an increase in positive mood. Employees’ regulatory focus was found to moderate the indirect within-person effects. This work expands the current understanding of employee voice by focusing on a dynamic within-person perspective, explores new determinants at the dynamic level, and extends the knowledge of the interplay of momentary states and personal traits at the workplace.

Open to Contact? Increased State Openness Can Lead to Greater Interest in Contact With Diverse Groups.

Contact is a reliable method of prejudice reduction. However, individuals higher in prejudice are less interested in contact with diverse groups. This research investigates a novel method of encouraging interest in contact, particularly for those lower in the personality trait of Openness/Intellect, who tend to be higher in prejudice. Although long-term traits are relatively stable, momentary personality states show considerable within-person variation, and can be manipulated. In two experimental studies (total N = 687), we tested whether inducing higher state Openness would affect interest in contact. In Study 1, those lower in trait Openness/Intellect showed a positive indirect effect of condition on two outcome measures, via greater state Openness. In a larger sample with lower trait Openness/Intellect (Study 2), the indirect effect on the first outcome was replicated, regardless of disposition. The findings suggest that experiencing open states more frequently could encourage contact and lead to eventual reductions in prejudice.

The Joyful Life: An Existential-Humanistic Approach to Positive Psychology in the Time of a Pandemic.

In the midst of a global pandemic, psychology has a duty to identify dispositional or character traits that can be cultivated in citizens in order to create resiliency in the face of profound losses, suffering and distress. Dispositional joy holds some promise as such a trait that could be especially important for well-being during the current pandemic and its consequences. The concept of the Joyful Life may operate as bridge between positive psychology and humanistic, existential, and spiritual views of the good life, by integrating hedonic, prudential, eudaimonic and chaironic visions of the good life. Previous phenomenological research on state joy suggests that momentary states of joy may have features that overlap with happiness but go beyond mere hedonic interests, and point to the experience of a life oriented toward virtue and a sense of the transcendent or the sacred. However, qualitative research on the Joyful Life, or dispositional joy, is sorely lacking. This study utilized a dialogical phenomenological analysis to conduct a group-based analysis of 17 volunteer students, who produced 51 autobiographical narrative descriptions of the joyful life. The dialogical analyses were assisted by integration of the Imagery in Movement Method, which incorporated expressive drawing and psychodrama as an aid to explicate implicit themes in the experiences of the participants. The analyses yielded ten invariant themes found across the autobiographical narrative descriptions: Being broken, being grounded, being centered, breaking open, being uplifted, being supertemporal, being open to the mystery, being grateful, opening up and out, and being together. The descriptions of a Joyful Life were consistent with a meaning orientation to happiness, due to their emphasis on the cultivation of virtue in the service of a higher calling, the realization of which was felt to be a gift or blessing. The discussion examines implications for future research, including the current relevance of a joyful disposition during a global pandemic. Due to the joyful disposition’s tendency to transform suffering and tragedy into meaning, and its theme of an orientation to prosocial motivations, the Joyful Life may occupy a central place in the study of resiliency and personal growth in response to personal and collective trauma such as COVID-19.

Physics interpretation of ISO/CIE sky types

Sky luminance distribution, itself immensely variable solar radiation product, is an indispensable prerequisite for any daylight availability assessment. Currently, prediction-based modeling is a key ingredient of daylight qualification worldwide, while ISO/CIE general sky standard is an essential tool accommodated for simulation purposes. Due to its long term perspective and a number of benefits (e.g. simple mathematics and easy numerical implementation), the model is applied routinely and independent of meteorological conditions prevailing on a regional scale. ISO/CIE classifies sky states into fifteen subtypes on statistical base, however, with no relation to e.g. local sources of pollution. In result, the statistics found for two different territories may accidentally cohere for which there is really no theoretical reason. Here we show that the physics interpretation of sky states is needed for a proper use of the ISO/CIE model in different territories through linking the luminance distributions with atmospheric properties, specifically τ and g. The latter shapes the angular distribution of scattered light, while τ is interpreted in term of atmospheric optical thickness. The new approach we present here not only profits from its theoretical foundation, but both τ and g can be easily derived from the momentary local atmosphere state. This way the characterization of sky states and a use of ISO/CIE skies can be more selective and more systematic.

These and their connections with other matter was widely studied in the field of aging. In this review we comparatively discuses all the methods and their theories. It will be very helpful for other readers to choose any methods to carry out better results.

A tablet-based intervention for activating nursing home residents with dementia: results from a cluster-randomized controlled trial.

To investigate global and momentary effects of a tablet-based non-pharmacological intervention for nursing home residents living with dementia. Cluster-randomized controlled trial. Ten nursing homes in Germany were randomly allocated to the tablet-based intervention (TBI, 5 units) or conventional activity sessions (CAS, 5 units). N = 162 residents with dementia. Participants received regular TBI (n = 80) with stimulating activities developed to engage people with dementia or CAS (n = 82) for 8 weeks. Apathy Evaluation Scale (AES-I, primary outcome), Quality of Life in Alzheimer's Disease scale, QUALIDEM scale, Neuropsychiatric Inventory, Geriatric Depression Scale, and psychotropic medication (secondary outcomes). Momentary quality of life was assessed before and after each activity session. Participants and staff were blinded until the collection of baseline data was completed. Data were analyzed with linear mixed-effects models. Levels of apathy decreased slightly in both groups (mean decrease in AES-I of .61 points, 95% CI -3.54, 2.33 for TBI and .36 points, 95% CI -3.27, 2.55 for CAS). Group difference in change of apathy was not statistically significant (β = .25; 95% CI 3.89, 4.38, p = .91). This corresponds to a standardized effect size (Cohen's d) of .02. A reduction of psychotropic medication was found for TBI compared to CAS. Further analyses revealed a post-intervention improvement in QUALIDEM scores across both groups and short-term improvements of momentary quality of life in the CAS group. Our findings suggest that interventions involving tailored activities have a beneficial impact on global and momentary quality of life in nursing home residents with dementia. Although we found no clear advantage of TBI compared to CAS, tablet computers can support delivery of non-pharmacological interventions in nursing homes and facilitate regular assessments of fluctuating momentary states.

Perceived disturbance and predictors thereof in studies using the experience sampling method

Intensive repeated momentary diary techniques, such as the experience sampling method (ESM), place considerable burden on study participants by repeatedly prompting them to fill in a questionnaire several times throughout the day. The objective of this study was to investigate the level of disturbance reported by participants and predictors thereof using a pooled dataset of seven ESM studies including 1319 healthy participants and individuals with different mental health conditions. All studies used a design of 10 prompts per day over the course of 4 to 6 days. Participants reported no disturbance at 37% of the measurement occasions and the overall level of disturbance was relatively low. Also, clinical samples did not report significantly different levels of disturbance compared to the healthy participants. However, higher levels of disturbance were found for later study days, in the morning, and on weekends. Also, younger participants reported feeling more disturbed by the prompts. In terms of momentary states, higher levels of activity, activity stress, and tiredness were associated with higher disturbance. Also, participants experienced more disturbance when in company compared to when alone, and the level of disturbance increased when in company with less familiar people. Our findings suggest that studies using high-frequency ESM protocols can be used in mental health research, but researchers should be aware of the possible disturbance caused by their research design.

Personality-place transactions: Mapping the relationships between Big Five personality traits, states, and daily places.

People actively select their environments, and the environments they select can alter their psychological characteristics in the moment and over time. Such dynamic person-environment transactions are likely to play out in the context of daily life via the places people spend time in (e.g., home, work, or public places like cafes and restaurants). This article investigates personality-place transactions at 3 conceptual levels: stable personality traits, momentary personality states, and short-term personality trait expressions. Three 2-week experience sampling studies (2 exploratory and 1 confirmatory with a total N = 2,350 and more than 63,000 momentary assessments) were used to provide the first large-scale evidence showing that people's stable Big Five traits are associated with the frequency with which they visit different places on a daily basis. For example, extraverted people reported spending less time at home and more time at cafés, bars, and friends' houses. The findings also show that spending time in a particular place predicts people's momentary personality states and their short-term trait expression over time. For example, people reported feeling more extraverted in the moment when spending time at bars/parties, cafés/restaurants, or friends' houses, compared with when at home. People who showed preferences for spending more time in these places also showed higher levels of short-term trait extraversion over the course of 2 weeks. The findings make theoretical contributions to environmental psychology, personality dynamics, as well as the person-environment transactions literature, and highlight practical implications for a world in which the places people visit can be easily captured via GPS sensors.

Fluctuations in grandiose and vulnerable narcissistic states: A momentary perspective.

Theories of narcissism emphasize the dynamic processes within and between grandiosity and vulnerability. Research seeking to address this has either not studied grandiosity and vulnerability together or has used dispositional measures to assess what are considered to be momentary states. Emerging models of narcissism suggest grandiosity and vulnerability can further be differentiated into a three-factor structure-Exhibitionistic Grandiosity, Entitlement, and Vulnerability. Research in other areas of maladaptive personality (e.g., borderline personality disorder) has made headway in engaging data collection and analytic methods that are specifically meant to examine such questions. The present study took an exploratory approach to studying fluctuations within and between grandiose and vulnerable states. Fluctuations-operationalized as gross variability, instability, and lagged effects-were examined across three samples (two undergraduate and a community sample oversampled for narcissistic features; total person N = 862, total observation N = 36,631). Results suggest variability in narcissistic states from moment to moment is moderately associated with dispositional assessments of narcissism. Specifically, individuals who are dispositionally grandiose express both grandiosity and vulnerability, and vary in their overall levels of grandiosity and vulnerability over time. On the other hand, dispositionally vulnerable individuals tend to have high levels of vulnerability and low levels of grandiosity. Entitlement plays a key role in the processes that underlie narcissism and narcissistic processes appear unique to the construct and not reflective of broader psychological processes (e.g., self-esteem). Future research should consider using similar methods and statistical techniques on different timescales to study dynamics within narcissism.

Social Functioning and Social Cognition in Schizophrenia and Bipolar Disorder: Using Ecological Momentary Assessment to Identify the Origin of Bias Self Reports

People with schizophrenia (SCZ) and bipolar illness (BPI) generate self-reports of their functioning that diverge from objective information. It has been suggested that these participants do not base their reports on their daily experiences, relying on momentary mood states instead. We used ecological momentary assessment (EMA) to sample socially relevant daily activities in SCZ and BPI and related them to self and observer reports of social functioning and social cognitive ability.

DeepConnection: classifying momentary relationship state from images of romantic couples

Detecting momentary relationship state and quality in romantic couples is an important endeavor for relationship research, couple therapy, and of course couples themselves. Yet current methods to achieve this are intrusive, asynchronous, plagued by ceiling effects, and only assess subjective responses to questionnaires while trying to capture the objective state of a relationship. According to social appraisal theory, human beings rely on emotional responses to assess interpersonal situations, a key element for relationship functioning in couples. Using couples is particularly advantageous as strong emotional reactions are triggered in romantic relationships. Here, we employ deep learning methods to assess the momentary relationship state of romantic couples from predominantly stock images via facial and bodily emotion expression and other features. Our new model, DeepConnection, comprises pre-trained residual neural networks, spatial pyramid pooling layers, and power mean transformations to extract relevant features from images for binary classification. With this, we achieved an average accuracy of nearly 97% on a separate validation dataset. We also engaged in model interpretation using Gradient-weighted Class Activation Mapping (Grad-CAM) to identify which features allow DeepConnection to detect binarized momentary relationship state. To demonstrate generalizability and robustness, we used DeepConnection to analyze videos of couples exhibiting a range of different postures and facial expressions. Here, we achieved an average accuracy of about 85% with a trained DeepConnection model. The work presented here could inform couples, advance relationship research, and find application in couple therapy to assist the therapist.

The Digital Marshmallow Test (DMT) Diagnostic and Monitoring Mobile Health App for Impulsive Behavior: Development and Validation Study.

BackgroundThe classic Marshmallow Test, where children were offered a choice between one small but immediate reward (eg, one marshmallow) or a larger reward (eg, two marshmallows) if they waited for a period of time, instigated a wealth of research on the relationships among impulsive responding, self-regulation, and clinical and life outcomes. Impulsivity is a hallmark feature of self-regulation failures that lead to poor health decisions and outcomes, making understanding and treating impulsivity one of the most important constructs to tackle in building a culture of health. Despite a large literature base, impulsivity measurement remains difficult due to the multidimensional nature of the construct and limited methods of assessment in daily life. Mobile devices and the rise of mobile health (mHealth) have changed our ability to assess and intervene with individuals remotely, providing an avenue for ambulatory diagnostic testing and interventions. Longitudinal studies with mobile devices can further help to understand impulsive behaviors and variation in state impulsivity in daily life.ObjectiveThe aim of this study was to develop and validate an impulsivity mHealth diagnostics and monitoring app called Digital Marshmallow Test (DMT) using both the Apple and Android platforms for widespread dissemination to researchers, clinicians, and the general public.MethodsThe DMT app was developed using Apple’s ResearchKit (iOS) and Android’s ResearchStack open source frameworks for developing health research study apps. The DMT app consists of three main modules: self-report, ecological momentary assessment, and active behavioral and cognitive tasks. We conducted a study with a 21-day assessment period (N=116 participants) to validate the novel measures of the DMT app.ResultsWe used a semantic differential scale to develop self-report trait and momentary state measures of impulsivity as part of the DMT app. We identified three state factors (inefficient, thrill seeking, and intentional) that correlated highly with established measures of impulsivity. We further leveraged momentary semantic differential questions to examine intraindividual variability, the effect of daily life, and the contextual effect of mood on state impulsivity and daily impulsive behaviors. Our results indicated validation of the self-report sematic differential and related results, and of the mobile behavioral tasks, including the Balloon Analogue Risk Task and Go-No-Go task, with relatively low validity of the mobile Delay Discounting task. We discuss the design implications of these results to mHealth research.ConclusionsThis study demonstrates the potential for assessing different facets of trait and state impulsivity during everyday life and in clinical settings using the DMT mobile app. The DMT app can be further used to enhance our understanding of the individual facets that underlie impulsive behaviors, as well as providing a promising avenue for digital interventions.Trial RegistrationClinicalTrials.gov NCT03006653; https://www.clinicaltrials.gov/ct2/show/NCT03006653

Networks of stress, affect and eating behaviour: anticipated stress coping predicts goal-congruent eating in young adults

BackgroundMany people aim to eat healthily. Yet, affluent food environments encourage consumption of energy dense and nutrient-poor foods, making it difficult to accomplish individual goals such as maintaining a healthy diet and weight. Moreover, goal-congruent eating might be influenced by affects, stress and intense food cravings and might also impinge on these in turn. Directionality and interrelations of these variables are currently unclear, which impedes targeted intervention. Psychological network models offer an exploratory approach that might be helpful to identify unique associations between numerous variables as well as their directionality when based on longitudinal time-series data.MethodsAcross 14 days, 84 diet-interested participants (age range: 18–38 years, 85.7% female, mostly recruited via universities) reported their momentary states as well as retrospective eating episodes four times a day. We used multilevel vector autoregressive network models based on ecological momentary assessment data of momentary affects, perceived stress and stress coping, hunger, food craving as well as goal-congruent eating behaviour.ResultsNeither of the momentary measures of stress (experience of stress or stress coping), momentary affects or craving uniquely predicted goal-congruent eating. Yet, temporal effects indicated that higher anticipated stress coping predicted subsequent goal-congruent eating. Thus, the more confident participants were in their coping with upcoming challenges, the more they ate in line with their goals.ConclusionMost eating behaviour interventions focus on hunger and craving alongside negative and positive affect, thereby overlooking additional important variables like stress coping. Furthermore, self-regulation of eating behaviours seems to be represented by how much someone perceives a particular eating episode as matching their individual eating goal. To conclude, stress coping might be a potential novel intervention target for eating related Just-In-Time Adaptive Interventions in the context of intensive longitudinal assessment.

Role of Avoidance-Motivation Intensity in Creative Thinking: Similar and Differential Effects across Creative Idea Generation and Evaluation

ABSTRACT Dynamic, momentary affective states have significant effects on creativity; however, how negative affect modulates the neurocognitive processes involved in creativity is still unclear. This study investigated the neural mechanisms of creative thinking under varying avoidance-motivation intensity. Sixty participants (17 men and 43 women; age range = 18–25 years; mean = 21.22 years, SD = 1.35) randomly assigned to three groups (high-avoidance-motivation, low-avoidance-motivation, and unmotivated bias state) completed creative tasks in two conditions – creative idea generation and creative idea evaluation. In the former condition, the low-avoidance-motivation group exhibited greater fluency of divergent thinking than the high-avoidance-motivation group. Functional near-infrared spectroscopy revealed an interaction effect between creative demand and avoidance-motivation intensity in the bilateral inferior frontal gyrus and right middle frontal gyrus in creative idea generation. In the latter condition, there were no significant differences between the three avoidance motivation groups in behavior and brain activation results. Furthermore, the association of the prefrontal cortex and temporal region in these tasks indicated that these regions may be part of the core mechanism underlying the modulatory effects of avoidance-motivation intensity on ongoing neurocognitive processing during creative thinking.

Quantum States in Templated Biological Processes

Living matter is characterized by its variegated potential energy landscape possessing a proneness to continually absorb externally supplied energy. This enables it to ascend from its momentary energy minimum state to one of its myriad barriers only to subsequently descend to a new minimum with a potentiality to perform new functions or processes, in the while exuding energy (mainly in the form of heat). As in studies of molecular intersystem crossing, the jumping processes are describable in terms of quantum states. In this work we derive the low energy quantum states for those three templated self-assembling processes, self-replication, metabolism and self-repair that are commonly regarded as distinguishing animate from inanimate substance. The outcome of each process is a new, long-living, stable molecular aggregate characterized by its specific conformation, comprising a host of micro-states associated with sub-conformations and patterned upon the template. The provenance of these newly-formed states is obtained here by a unified formalism for all three processes, based on a Hamiltonian, constructed in an abstract Hilbert-space framework, whose essences are bilinear coupling terms in the Hamiltonian between the template and the bath, as well as between the reactants and the bath. Treating these terms by second order perturbation, one finds in low lying quantum states an alignment between the template and the product, somewhat analogous to the Kramers-Anderson superexchange mechanism, with the bath replacing the bridging anion and by exploitation of the decohering due to the randomness of the bath. The idea underlying this work, recurrent in the biological literature and here expressed in a Physics, Hamiltonian framework, is the correlative unity of the whole biological system comprising multiple organs.

Boundary-anchored neural mechanisms of location-encoding for self and others.

Everyday tasks in social settings require humans to encode neural representations of not only their own spatial location, but also the location of other individuals within an environment. At present, the vast majority of what is known about neural representations of space for self and others stems from research in rodents and other non-human animals1-3. However, it is largely unknown how the human brain represents the location of others, and how aspects of human cognition may affect these location-encoding mechanisms. To address these questions, we examined individuals with chronically implanted electrodes while they carried out real-world spatial navigation and observation tasks. We report boundary-anchored neural representations in the medial temporal lobe that are modulated by one's own as well as another individual's spatial location. These representations depend onone's momentary cognitive state, and arestrengthened when encoding of location is of higher behavioural relevance. Together, these results provide evidence for a common encoding mechanism in the human brain that represents the location of oneself and others in shared environments, and shed new light on the neural mechanisms that underlie spatial navigation and awareness of others in real-world scenarios.

You can’t always get what you want: The role of change goal importance, goal feasibility and momentary experiences for volitional personality development

Most adults want to change aspects of their personality. However, previous studies have provided mixed evidence on whether such change goals can be successfully implemented, perhaps partly due to neglecting the goals’ importance and feasibility as well as the experience of trait-relevant situations and states. This study examined associations between change goals and changes in self-reported Big Five traits assessed four times across two years in an age-heterogeneous sample of 382 adults (255 younger adults, Mage = 21.6 years; 127 older adults, Mage = 67.8 years). We assessed trait-relevant momentary situations and states in multiple waves of daily diaries over the first year ( M = 43.9 days). Perceived importance and feasibility of change goals were analysed as potentially moderating factors. Contrary to our hypotheses, the results demonstrated that neither change goals nor goal importance or feasibility were consistently associated with trait change, likely due to inconsistent associations with momentary situations and behaviours. The results suggest that wanting to change one’s traits does not necessarily lead to changes without engaging in trait-relevant situations and behaviours. These findings provide novel insights into the boundary conditions of volitional personality development.
