Climate change beliefs, emotions and pro-environmental behaviors among adults: The role of core personality traits and the time perspective.

Climate change and its consequences are recognized as one of the most important challenges to the functioning of the Earth's ecosystem and humanity. However, the response to the threat posed by the climate crisis still seems inadequate. The question of which psychological factors cause people to engage (or not) in pro-environmental behavior remains without a comprehensive answer. The aim of this study is to establish the links between the cognitive (level of knowledge about climate change and degree of belief in climate myths), emotional (various climate emotions, especially climate anxiety) and behavioral aspects of attitudes towards the climate crisis and their determinants in the form of the Big Five personality domains and time perspectives. The stated hypotheses were verified by analyzing data collected in an online survey of 333 adults using knowledge tests and self-report methods, including psychological questionnaires (Climate Change Anxiety Scale by Clayton and Karazsia, Big Five Inventory-short version by Schupp and Gerlitz, and Zimbardo Time Perspective Inventory by Zimbardo and Boyd), and measurement scales developed for this study (Climate myth belief scale, Climate emotion scale, and Inventories of current and planned pro-environmental activities). The results of stepwise regression analysis demonstrate the importance of the core personality traits and the dominant temporal perspective as determinants of belief in climate change myths, climate anxiety, as well as actual and planned pro-environmental behavior.

Time perspective, future anxiety, and hope for success in individuals awaiting bariatric surgery.

BACKGROUND: The paper focuses on the problems of temporal functioning of obese individuals and of individuals prepared for bariatric treatment. The experience of time heavily weighs on many areas of human functioning, everyday activity, planning and achieving goals, engaging in pro-health behaviours, and in consequence on the quality of life and on physical health. Contingent on numerous factors, obesity may be related to focusing on particular aspects of time perspective. The aim of the study was to determine the specificity of particular temporal dispositions in individuals prepared for bariatric surgery, and thus to devise suitable post-op psychological interventions. PARTICIPANTS AND PROCEDURE: The study sample comprised 28 individuals (60.7% women, mean age M = 43.82 years, SD = 10.01, mean BMI M = 44.83 kg/m2, SD = 6.51) awaiting bariatric surgery. The data were collected individually with the following pen-and-paper questionnaires: the Zimbardo Time Perspective Inventory, the Dark Future Scale, and the Polish adaptation of Snyder's Adult Hope Scale, which is named the Hope for Success Questionnaire. RESULTS: The results showed the prevalence of present hedonistic time perspective in the obese. With regard to future anxiety or the hope for success, no significant deviations from the general population were observed. CONCLUSIONS: The results indicate that this group is in need of temporal psychotherapy aimed at balancing the time perspective. The results may also be interpreted through the lens of contextual determinants connected with task orientation preceding the surgery.

The Severity of Traumatic Stress Associated with COVID-19 Pandemic, Perception of Support, Sense of Security, and Sense of Meaning in Life among Nurses: Research Protocol and Preliminary Results from Poland.

The COVID-19 pandemic can not only affect physical health, but also mental health, resulting in sleep problems, depression, and traumatic stress. Our research investigates the level of posttraumatic stress, perceived social support, opinions on positive and negative consequences of the pandemic, sense of security and sense of meaning among nurses in the face of this new and not fully understood global epidemiological phenomenon. For this purpose, computer-assisted web interviews were conducted between May 1 and May 15, 2020. Participating nurses completed the following research tools: The Impact Event Scale-Revised (IES-R), The Multidimensional Scale of Perceived Social Support (MSPSS), The Changes in Outlook Questionnaire (CIOQ), The Safety Experience Questionnaire (SEQ) and The Meaning in Life Questionnaire (MLQ). Three hundred and twenty-five nurses of an average age of 39.18 ± 11.16 years and working throughout Poland joined the study. The average overall IES-R score in the study group was 1.78 ± 0.65. Among the dimensions of traumatic stress, the highest score was obtained in the "avoidance" dimension was 1.86 ± 0.73. Amongst participating nurses, the highest support rates were provided by significant others (22.58 ± 5.22). Higher average scores were noted among participants in the subscale measuring positive psychological changes (18.56 ± 4.04). The mean MLQ score was 5.33 ± 0.87. A slightly higher result was observed in the subscale "presence" (5.35 ± 1.14). The results of the research implemented during the period of severe psychological pressure associated with the COVID-19 pandemic provided information on symptoms of traumatic stress in the examined group of nurses. Their sense of security has been lowered and accompanied by an intensified reflection on issues concerning security. However, their current sense of meaning in life remains higher than the tendency to searching for it. The surveyed nurses received individual support mostly from significant others (i.e., other than family and friends). They see positive changes resulting from painful experiences related to the COVID-19 pandemic, which can be characterized by adaptation in the form of post-traumatic growth.

Direct and Indirect Relationships Between Life Satisfaction, Values, and Time Perspectives: Research on a Sample of Polish Students.

This study concerned the relationships among personal values (conformity, tradition, benevolence, universality, self-direction, stimulation, hedonism, achievement, power, safety), time perspectives by Zimbardo (past negative, past positive, present hedonistic, present fatalistic, future) and life satisfaction. The main hypothesis stated that value priorities would predict life satisfaction both directly and indirectly through time perspectives. 237 Polish students (120 females) took part in the study. Path analysis demonstrated that life satisfaction was directly and positively predicted by the value of benevolence, and indirectly and negatively by conformity and tradition via the past negative time perspective. Life satisfaction was also indirectly predicted by the values of hedonism and security via the future time perspective - Hedonism was a negative, and security a positive predictor of future time perspective, and the future time perspective was a positive predictor of life satisfaction. The significance of these results for mechanisms and predictors of life satisfaction is discussed.

Diurnal patterns of activity of the orienting and executive attention neuronal networks in subjects performing a Stroop-like task: a functional magnetic resonance imaging study.

Attentional processes are fundamental to good cognitive functioning of human operators. The purpose of this study was to analyze the activity of neuronal networks involved in the orienting attention and executive control processes from the perspective of diurnal variability. Twenty-three healthy male volunteers meeting magnetic resonance (MR) inclusion criteria performed the Stroop Color-Word task (block design) in the MR scanner five times/day (06:00, 10:00, 14:00, 18:00, 22:00 h). The first scanning session was scheduled 1-1.5 h after waking. Between MR sessions, subjects performed simulated driving tasks in stable environmental conditions, with controlled physical activity and diet. Significant activation was found in brain regions related to the orienting attentional system: the parietal lobe (BA40) and frontal eye-fields (FEFs). There were also activations in areas of the executive control system: the fronto-insular cortex (FIC), dorsal anterior cingulate cortex (dACC), presupplementary motor area (preSMA), supplementary motor area (SMA), basal ganglia, middle temporal (MT; BA21), and dorsolateral prefrontal cortex (DLPFC), as a part of the central executive network. Significant deactivations were observed in the rostral anterior cingulate cortex (rACC), posterior cingulate cortex (PCC), superior frontal gyrus (SF), parietal lobe (BA39), and parahippocampal that are thought to comprise the default mode network (DMN). Additionally, the activated regions included bilaterally lingual gyrus and fusiform gyrus. The insula was bilaterally deactivated. Visual attention controlled by the goal-oriented attention system and comprising top-down and bottom-up mechanisms, activated by Stroop-like task, turned out to be prone to diurnal changes. The study results show the occurrence of time-of-day-related variations in neural activity of brain regions linked to the orienting attentional system (left parietal lobe-BA40, left and right FEFs), simultaneously providing arguments for temporal stability of the executive system and default mode network. These results also seem to suggest that the involuntary, exogenous (bottom-up) mechanism of attention is more vulnerable to circadian and fatigue factors than the voluntary (top-down) mechanism, which appear to be maintained at the same functional level during the day. The above phenomena were observed at the neural level.

Chronic sleep deficit and performance of a sustained attention task--an electrooculography study.

Electrooculography (EOG) was used to explore performance differences in a sustained attention task during rested wakefulness (RW) and after 7 days of partial sleep deprivation (SD). The RW condition was based on obtaining regular sleep, and the SD condition involved sleep restriction of 3 h/night for a week resulting in a total sleep debt of 21 h. The study used a counterbalanced design with a 2-wk gap between the conditions. Participants performed a sustained attention task for 45 min on four occasions: 10:00-11:00, 14:00-15:00, 18:00-19:00, and 22:00-23:00 h. The task required moving gaze and attention as fast as possible from a fixation point to a target. In each session, 120 congruent and 34 incongruent stimuli were presented, totaling 1232 observations/participant. Correct responses plus errors of omission (lapses) and commission (false responses) were recorded, and the effect of time-of-day on sustained attention following SD was investigated. The analysis of variance (ANOVA) model showed that SD affected performance on a sustained attention task and manifested itself in a higher number of omission errors: congruent stimuli (F((1,64)) = 13.3, p < .001) and incongruent stimuli (F((1,64)) = 14.0, p < .001). Reaction times for saccadic eye movements did not differ significantly between experimental conditions or by time-of-day. Commission errors, however, exhibited a decreasing trend during the day. The visible prevalence of omissions in SD versus RW was observed during the mid-afternoon hours (the so-called post-lunch dip) for both congruent and incongruent stimuli (F((1,16)) = 5.3, p = .04 and F((1,16)) = 5.6, p = .03, respectively), and at 18:00 h for incongruent stimuli (F((1,13)) = 5.7, p = .03).

Chronotype, sleep loss, and diurnal pattern of salivary cortisol in a simulated daylong driving.

The study focused on chronotype-related differences in subjective load assessment, sleepiness, and salivary cortisol pattern in subjects performing daylong simulated driving. Individual differences in work stress appraisal and psychobiological cost of prolonged load seem to be of importance in view of expanding compressed working time schedules. Twenty-one healthy, male volunteers (mean +/- SD: 27.9 +/- 4.9 yrs) were required to stay in semiconstant routine conditions. They performed four sessions (each lasting approximately 2.5 h) of simulated driving, i.e., completed chosen tasks from computer driving games. Saliva samples were collected after each driving session, i.e., at 10:00-11:00, 14:00-15:00, 18:00-19:00, and 22:00-23:00 h as well as 10-30 min after waking (between 05:00 and 06:00 h) and at bedtime (after 00:00 h). Two subgroups of subjects were distinguished on the basis of the Chronotype Questionnaire: morning (M)- and evening (E)-oriented types. Subjective data on sleep need, sleeping time preferences, sleeping problems, and the details of the preceding night were investigated by questionnaire. Subjective measures of task load (NASA Task Load Index [NASA-TLX]), activation (Thayer's Activation-Deactivation Adjective Check List [AD ACL]), and sleepiness (Karolinska Sleepiness Scale [KSS]) were applied at times of saliva samples collection. M- and E-oriented types differed significantly as to their ideal sleep length (6 h 54 min +/- 44 versus 8 h 13 min +/- 50 min), preferred sleep timing (midpoint at 03:19 versus 04:26), and sleep index, i.e., 'real-to-ideal' sleep ratio, before the experimental day (0.88 versus 0.67). Sleep deficit proved to be integrated with eveningness. M and E types exhibited similar diurnal profiles of energy, tiredness, tension, and calmness assessed by AD ACL, but E types estimated higher their workload (NASA-TLX) and sleepiness (KSS). M types exhibited a trend of higher mean cortisol levels than E types (F = 4.192, p < .056) and distinct diurnal variation (F = 2.950, p < .019), whereas E types showed a flattened diurnal curve. Cortisol values did not correlate with subjective assessments of workload, arousal, or sleepiness at any time-of-day. Diurnal cortisol pattern parameters (i.e., morning level, mean level, and range of diurnal changes) showed significant positive correlations with sleep length before the experiment (r = .48, .54, and .53, respectively) and with sleep index (r = .63, .64, and .56, respectively). The conclusions of this study are: (i) E-oriented types showed lower salivary cortisol levels and a flattened diurnal curve in comparison with M types; (ii) sleep loss was associated with lower morning cortisol and mean diurnal level, whereas higher cortisol levels were observed in rested individuals. In the context of stress theory, it may be hypothesized that rested subjects perceived the driving task as a challenge, whereas those with reduced sleep were not challenged, but bored/exhausted with the experimental situation.
