    Opis:
    This article examines how the arousing properties of words influence the local vs. global scope of perception in the Kimchi–Palmer task. It was assumed that arousal is a stimulus property that influences a person’s mental state. Suboptimal arousal (low or high) was expected to narrow the visual scope in comparison to optimal (moderate) arousal. Words varying in arousal (three levels) and matched for valence, concreteness, frequency of appearance, and length were read by 20 young adults (8 women and 12 men, Mage = 21.85, SD = 1.69). The participants were then asked about their scope of perception using the Kimchi–Palmer task, allowing for differentiation between the priority of processing on local versus global features of compound geometrical figures. The relationship between the arousal level of the words read and the subsequent cognitive scope followed the Yerkes-Dodson law in that stimuli inducing an intermediate arousal level (versus low or high level of arousal inducements) were associated with a broader, more global cognitive scope.

    Opis:
    The cognitive aspects like perception, problem-solving, thinking, task performance, etc., are immensely influenced by emotions making it necessary to study emotions. The best state of emotion is the positive unexcited state, also known as the HighValence LowArousal (HVLA) state of the emotion. The psychologists endeavour to bring the subjects from a negatively excited state of emotion (Low Valence High Arousal state) to a positive unexcited state of emotion (High Valence Low Arousal state). In the first part of this study, a four-class subject independent emotion classifier was developed with an SVM polynomial classifier using average Event Related Potential (ERP) and differential average ERP attributes. The visually evoked Electroencephalogram (EEG) signals were acquired from 24 subjects. The four-class classification accuracy was 83% using average ERP attributes and 77% using differential average ERP attributes. In the second part of the study, the meditative intervention was applied to 20 subjects who declared themselves negatively excited (in Low Valence High Arousal state of emotion). The EEG signals were acquired before and after the meditative intervention. The four-class subject independent emotion classifier developed in Study 1 correctly classified these 20 subjects to be in a negatively excited state of emotion. After the intervention, 16 subjects self-assessed themselves to be in a positive unexcited (HVLA) state of emotion (which shows the intervention accuracy of 80%). Testing a four-class subject independent emotion classifier on the EEG data acquired after the meditative intervention validated 13 of 16 subjects in a positive unexcited state, yielding an accuracy of 81.3%.

    Opis:
    The aim of this paper was to contribute to a broader understanding of the cognitive consequences of expressive suppression. Specifically, we examined whether the deteriorating effect of expressive suppression on cognitive functioning is caused by tense arousal enhanced by suppression. Two experiments were performed in order to test this prediction. In both studies we tested the effect of expressive suppression on working memory, as measured with a backwards digit-span task (Study 1, N = 43) and anagram problem-solving task (Study 2, N = 60). In addition, in Study 2 we tested whether expressive suppression degrades memory of the events that emerged during the period of expressive suppression. Both studies were conducted in a similar design: Participants watched a film clip which evoked negative emotions (i.e. disgust in Study 1 and a combination of sadness and anxiety in Study 2) under the instruction to suppress those negative emotions or (in the control condition) to simply watch the film. The results of these experiments lead to three conclusions. First, the results reveal that expressive suppression degrades memory of the events that emerged during the period of expressive suppression and leads to poorer performance on working memory tasks, as measured with a backwards digit-span task and anagram problem-solving task. Second, the results indicate that expressive suppression leads to a significant increase in subjective tense arousal. Third, the results support our prediction that expressive suppression decreases cognitive performance through its effects on subjective tense arousal. The results of the Study 1 show that tense arousal activated during expressive suppression of disgust fully mediates the negative effect of suppression on working memory as measured with a backwards digit-span task. The results of Study 2 reveal that subjective tense arousal elicited while suppressing sadness and anxiety mediates both the effect of suppression on working memory - as measured with the anagram task - and memory of the events that occurred during the period of suppression.

    Opis:
    The paper discusses the influence of FaceReader-coded emotional arousal and valence on the effectiveness of civic education. The experimental design allowed the authors to observe relationships between emotional responsiveness and memorisation, attitude change, and prosocial behaviour. In the study with 90 adult participants, we video-recorded facial expressions while watching three parallel versions of a narrative on anti-communist opposition in Poland. The analysis of collected data suggested that emotional arousal is associated with prosocial behaviour and the valence of signalling with an attitude change, while cognitive effects are not related to emotional responsiveness. Moreover, civic education depends on the triad of emotions: sadness, happiness, and disgust.

    Opis:
    Objectives: Studies involving simulators are increasingly popular. We examined to what extent exposure to a variety of test conditions on the simulator affects the level of mood and severity of simulator sickness. In addition, we were interested in finding out to what degree the changes in mood are associated with the severity of the symptoms of simulator sickness. Material and Methods: Twelve men (aged M: 29.8, SD: 4.26) participated in the study, performing two 30-minute tasks in a driving simulator truck (fixed-base and mobile platform). For measuring mood, the UMACL questionnaire was used, and to assess the severity of the symptoms of simulator sickness, the SSQ questionnaire was used. Mood and the severity of simulator sickness symptoms were measured 3 times during the study (pretest, 2 min and 0.5 h after the test). Results: Symptoms of nausea and disorientation occurred after the tests on both simulators. In the case of the mobile platform, exacerbation of the symptoms associated with oculomotor disturbances was observed. These symptoms were particularly severe 2 min after completion of the test on the simulator, and they persisted for at least 0.5 h after the end of the test. The correlations between simulator sickness and mood explained from 35% to 65% of the variance of these variables. In particular, a strong association was observed between the oculomotor disturbances and a decrease in energetic arousal. This refers both to the effect level and the duration of these symptoms. Conclusions: Simulator sickness is a major problem in the use of simulators in both the research and the training of operators. In the conditions involving the mobile platform, not only was a higher severity of the symptoms of simulator sickness observed, but also a decrease in energetic arousal. Therefore, the implementation of the mobile platform can provide an additional source of conflict at the level of incoming stimuli and changes in mood may increase this effect. Thus, it seems important to consider the tasks performed on the simulator in the context of utility and the purpose for which we use them.

    Opis:
    Neurological early and long-term rehabilitation plays a crucial role in the therapy of patients with disorders of consciousness (DOC) such as unresponsive wakefulness syndrome or minimally conscious state. Neuroscience tries to explain the effect of music therapy on all levels of the nervous system = activity in patients with DOC, but full understanding is still incomplete. This paper attempts to answer how current clinical outcomes may reflect the influence of various factors including music's capacity. Based on their interdisciplinary perspective and previous experiences, the authors try to investigate the extent to which current occupations have been explored. The authors analyzed the literature data concerning the results of the studies published until the first half of 2016, to sum up the current state of research. Research in the main databases: PubMed, PEDro, Health Source: Nursing/Academic Edition was made using specified keywords and inclusion and exclusion criteria. Next, the authors sorted them all out into a coherent view of the current state. Music listening may constitute a part of an enriched environment setting. However, due to weak evidence, the therapeutic value of music-based interventions in patients with DOC is uneven or limited. The role of music therapy is thus complementary. Standardized clinical settings, protocols, and behavioral measures should be developed to increase its clinical validity, reliability, sensitivity, and objectivity. There is a reasonable hypothesis that music may produce a high level of diagnostic and therapeutic outcomes as stimuli usually reflecting strong personal meaning in patients with DOC.

    Opis:
    Almost four decades have passed since Dutton and Aron (1974) published their classic article in JPSP in which they present the results of three studies. According to interpretations of the results done by the authors, the suffi cient condition of obtaining the effect of increased sexual attraction toward the object (an attractive woman) – which must be present shortly after or while waiting to become an aversive stimulus – is the induction in the subjects of a strong autonomic arousal. This can be done via crossing a high suspended bridge or anticipating the receipt of strong electric shocks. However, the results of reanalysis do not allow such a conclusion. In the article the author presents the results of secondary analysis and lists methodological, theoretical and interpretative incoherences.

    Opis:
    Cel badań. Celem badań było sprawdzenie, jak wywołanie obrzydzenia moralnego wpływa na pożądanie i podniecenie seksualne. Metoda badań. Badaniu poddanych zostało 171 osób, w większości studentów wrocławskich uczelni wyższych. Została im zaprezentowana historia wywołująca obrzydzenie moralne (grupa badawcza) oraz historia neutralna (grupa kontrolna), z towarzyszącymi im zdjęciami bohaterów historii. Następnie badani wypełniali Kwestionariusz Podniecenia i Pożądania Seksualnego SADI, w ramach którego proszeni byli o przypomnienie sobie doznań towarzyszących ich ostatniemu doświadczeniu seksualnemu. Inwentarz ten składa się z czterech podskal: aspektu ewaluatywnego, aspektu negatywnego/awersyjnego, aspektu fizjologicznego i aspektu motywacyjnego. Wyniki badań. Nie wykryto istotnych statystycznie różnic wyników kwestionariusza SADI w trzech pozytywnych podskalach inwentarza: aspekcie ewaluatywnym, aspekcie fizjologicznym i aspekcie motywacyjnym. Świadczy to o braku wpływu obrzydzenia moralnego na to, jak wyraziste są pozytywne aspekty pożądania i podniecenia seksualnego. Wykryto jednak różnice w aspekcie negatywnym/awersyjnym Kwestionariusza Podniecenia i Pożądania – grupa obrzydzona moralnie miała statystycznie wyższe wyniki na tej podskali od grupy kontrolnej. Nie stwierdzono istotnych różnic międzypłciowych w tych zależnościach. Ograniczenia badań. Badanie zostało przeprowadzone na próbce homogenicznej pod względem wieku, wykształcenia i miejsca zamieszkania. Wnioski. Wyniki badania sugerują istnienie wpływu obrzydzenia moralnego na większą dostępność negatywnych elementów wspomnienia ostatniego seksualnego doświadczenia, niezależnie od utrzymującej się na tym samym poziomie dostępności elementów pozytywnych tego doświadczenia. Wcześniejsze badania sugerują, że obrzydzenie zaostrza sądy moralne, my zaś rozszerzamy tę zależność: obrzydzenie moralne zaostrza sądy ogólnie, także dotyczące negatywnych doznań seksualnych.
    Aim of research. Our aim was to find out whether eliciting moral disgust influences sexual arousal and desire. Methods. We conducted research on 171 participants, most of whom were university students. They were presented with a story eliciting moral disgust (experimental group) or a neutral story (control group), with photographs of the characters from the stories. Subsequently, the participants were asked to fill in the Sexual Arousal and Desire Scale, within which they had to remind themselves of their last sexual experiences. The scale consists of four sub-scales: evaluative, negative/aversive, physiological and motivational aspect. Results. No significant differences were found in terms of the three positive sub-scales: evaluative, physiological and motivational aspects. It indicates that moral disgust does not influence the vividness of positive aspects of sexual arousal and desire. However, discrepancies in the negative/aversive aspect of the SADI scale were found – morally disgusted participants were noted to have statistically higher scores in this sub-scale than the controls. No gender differences were found in these relationships. Limitations. The research was conducted on a group that was homogeneous with respect to age, education and the place of residence. Conclusions. The results imply that moral disgust has an influence on accessibility of negative elements of last sexual experience’s memories, regardless of accessibility of positive elements of such memories. Earlier studies suggested that disgust makes moral judgments more severe, and this study widens this relationship – moral disgust increases judgments in general, including the negative parts of sexual experiences.

    Opis:
    Objectives: The aim of this study was to verify psychometric properties of the Polish version of the Job-related Affective Well-being Scale (JAWS). Specifically, theoretical 4-factor structure (based on the dimensions of pleasure and arousal) and reliability of the original - 20-item JAWS (van Katwyk et al., 2000) and the shortened - 12-item (Schaufeli and Van Rhenen, 2006) versions were tested. Material and Methods: Two independent samples were analyzed (police officers, N = 395, and police recruits, N = 202). The Polish version of the original, 20-item, JAWS was used to measure job-related affective states across the past month (van Katwyk et al., 2000). This version of JAWS includes 2 dimensions: valence and arousal, which allow to assess 4 categories of emotions: low-arousal positive emotions, high-arousal positive emotions, lowarousal negative emotions and high-arousal negative emotions. Results: The results of multidimensional scaling analysis showed that the theoretical circumplex model of emotions underlining JAWS was satisfactorily reproduced. Also the hypothesized 4-factor structure of the Polish version of JAWS was confirmed. The 12-item version had better fit with the data than the original, 20-item, version, but the best fit was obtained for the even shorter, 8-item version. This version emerged from a multidimensional scaling of the 12-item version. Reliabilities of the 20- and 12-item versions were good, with lower values for the 8-item JAWS version. Conclusions: The findings confirmed satisfactory psychometric properties of both Polish versions of the Job-related Affective Well-being Scale. Thus, when both psychometric properties and relevance for cross-cultural comparisons are considered, the 12-item JAWS is recommended as a version of choice.

    Celem artykułu jest próba syntezy wiedzy dotyczącej przeciążenia/niedociążenia poznawczego pracowników, które ma wymierne konsekwencje dla efektów ich pracy. Tok wywodu zorganizowano w postaci 4 tez. (1) Efektywność wykonywania zadań zależy krzywoliniowo od PAO (poziomu aktywacji organizmu) pracownika (Yerkes i Dodson, 1908). Zależność ta jest efektem wpływu PAO na wielkość aktualnie dostępnych zasobów poznawczych. Wpływ emocji na poziom pobudzenia organizmu zależy od ich typu. (2) Wielkość pobudzenia tonicznego wyznaczają przede wszystkim cechy temperamentalne. Moderatorem związku PAO z temperamentem mogą być zarówno stałe cechy osobowościowe czy sytuacja socjodemograficzna, jak i cechy zmienne, takie jak poziom zmęczenia (niewyspanie, przeziębienie…). (3) Pobudzenie fazowe pracownika zależy nie tylko od obiektywnej sytuacji bodźcowej i wykonywanej aktywności, ale jest także moderowane przez automatycznie działające filtry percepcyjne, schematy poznawcze i celową aktywność poznawczą przypisującą znaczenie bodźcom. (4) Pracownik zazwyczaj aktywnie wpływa na PAO podejmując działania o określonej wartości stymulacyjnej. Widoczne są duże różnice w preferencjach co do typu stymulacji (intelektualna, fizyczna, społeczna…).
    The goal of the current article is an attempt to synthesize the knowledge on the consequences of cognitive overload/underload of the employees on their work outcomes. The course of the argument has been organized in the form of 4 theses. (1) Employee performance depends curvilinearly on the level of arousal (Yerkes i Dodson, 1908). This relationship is affected by the size of the available cognitive resources. The effect of emotions on the level of arousal depends on their type. (2) The magnitude of tonic arousal is primarily defined by the temperamental traits. The relationship between the arousal level and the temperament can be moderated by permanent personality traits, sociodemographic situation, as well as variable features, such as the level of fatigue (lack of sleep, cold…). (3). Employee’s phasic arousal depends not only on the objective stimuli and performed activity, but can also be moderated by the automatically operating perceptual filters, cognitive schemas, and a deliberate cognitive activity aimed at assigning meaning to the stimuli. (4). An employee can actively influence his/her arousal level by undertaking activities of a certain stimulative value. There are large differences regarding the type of preferred stimulation (intellectual, physical, social…).

    Opis:
    In this article, we present a comprehensive measurement system to determine the level of user emotional arousal by the analysis of electrodermal activity (EDA). A number of EDA measurements were collected, while emotions were elicited using specially selected movie sequences. Data collected from 16 participants of the experiment, in conjunction with those from personal questionnaires, were used to determine a large number of 20 features of the EDA, to assess the emotional state of a user. Feature selection was performed using signal processing and analysis methods, while considering user declarations. The suitability of the designed system for detecting the level of emotional arousal was fully confirmed, throughout the number of experiments. The average classification accuracy for two classes of the least and the most stimulating movies varies within the range of 61‒72%.

    Celem badania było sprawdzenie wpływu podania glukozy, oraz pobudzenia emocjonalnego, na pamięć. Uczestnikami byli studenci przydzieleni losowo do grup glukozy (50 g glukozy) i grup placebo (50,6 mg sacharyny), a następnie podzieleni na grupy o wysokim i niskim poziomie podniecenia emocjonalnego. Grupom o wysokim i niskim poziomie podniecenia emocjonalnego pokazano zestaw slajdów, którego treść była odpowiednio pobudzająca emocjonalnie lub neutralna emocjonalnie. Wykonano pomiary glukozy we krwi, a testy pamięci i rozpoznawania były przeprowadzane w różnych odstępach czasu w trakcie eksperymentu. Glukoza poprawiła pamięć natychmiastową tylko u kobiet, podczas gdy pobudzenie emocjonalne poprawiło zarówno pamięć natychmiastową, jak i przywoływanie wspomnień u wszystkich badanych. Pobudzenie emocjonalne poprawiło pamięć rozpoznawczą tylko u mężczyzn. Chociaż przedstawione w artykule odkrycia potwierdzają usprawniające działanie glukozy i pobudzenia emocjonalnego na pamięć, jednocześnie prowokują więcej pytań na temat różnic we wpływie tych dwóch czynników na pamięć u mężczyzn i kobiet.
    This study investigated the effect of glucose administration and emotional arousal on memory. Participants were undergraduate college students randomly assigned to glucose (50 g glucose) and placebo groups (50.6 mg saccharine) and further divided into high and low emotional arousal groups. High and low emotional arousal groups were shown a slide show whose content was either emotionally arousing or emotionally neutral, respectively. Blood glucose measurements were taken, and memory recall and recognition tests were given at various intervals throughout the experiment. Glucose improved memory for immediate recall in females only, while emotional arousal resulted in enhanced immediate and delayed recall for all subjects. Furthermore, emotional arousal enhanced recognition memory for males only. While the present findings confirm the facilitatory effects of glucose and emotional arousal on memory, they simultaneously stimulate more questions on the differences in the effect of these two factors on memory in males versus females.
