    Affective disorders impact women’s health, with a lifetime prevalence of over twelve per cent. They have been correlated with reproductive cycle factors, under the regulation of hormonal circadian rhythms. In affective disorders, circadian rhythms may become desynchronized. The circadian rhythms of cortisol and estradiol may play a role in affective disorders. The purpose of this study was to explore the temporal relationship between the rhythms of cortisol and estradiol and its relationship to affect. It was hypothesized that a cortisol-estradiol phase difference (PD) exists that correlates with optimal affect. A small scale, comparative, correlational design was used to test the hypothesis. Twenty-three women were recruited from an urban university. Salivary samples were collected over a twenty-four-hour period and fitted to a cosinor model. Subjective measures of affect were collected. Relationships between the cortisol-estradiol PD and affect were evaluated using a second-degree polynomial equation. Results demonstrated a significant correlation in affect measures (p \u3c 0.05). An optimal PD was identified for affect to be 3.6 hours. The phase relationship between cortisol and estradiol may play a role in the development of alterations in affective disorders

    The final publication is available at Springer via http://dx.doi.org/10.1007/0-306-47532-4_5This paper describes the automatic generation of simulation-based Internet courses by means of an object-oriented continuous simulation language (OOCSMP), and a compiler for this language (C-OOL). Several multimedia extensions added to the language are also described. These extensions provide the student with a better understanding of the simulated models. The paper finally describes a course developed using the multimedia extensions

    P3 amplitude reductions are associated with shared variance between internalizing and externalizing psychopathology

    Full text link
    P3 amplitude reductions, commonly elicited in oddball paradigms, have been associated with both internalizing (e.g., depression and anxiety) and externalizing problems (e.g., substance use, aggression, and impulsivity). Recent factor analytic models have focused on the shared variance between internalizing and externalizing problems as a potentially important separable psychopathology construct (a general psychopathology factor, or p‐factor). To assess neurophysiological markers of this shared variance, we examined P3 amplitude to target and novel stimuli in an undergraduate sample with a range of internalizing and externalizing problems. Participants (N = 125) completed a rotated heads visual oddball paradigm, with IAPS pictures serving as infrequent novel stimuli. Results replicated P3 amplitude reduction relative to both target and novel stimuli separately for internalizing and externalizing problems, and found that the shared variance across internalizing and externalizing was significantly related to lower P3 amplitude to novels, targets, and a factor score of target and novel P3 measures. The present results are consistent with the interpretation that a general or shared problem behavior factor accounts for much of the associations between reduced P3 amplitude and internalizing and externalizing problems.There is a need for biological measures that can index emerging models of the shared variance between internalizing and externalizing problems (cf. general psychopathology factor, or p‐factor), to provide approaches for assessing the biological systems underlying these models. The current study found support for the idea that a general or shared problem behavior factor contributes to P3 amplitude reductions observed separately for internalizing and externalizing behaviors. This supports an inference that some biological systems are sensitive to processes associated with a shared problem behavior factor.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/155993/1/psyp13618_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/155993/2/psyp13618.pd

    The link between myths about sexual aggression and sexual objectification via hostile attitudes toward women

    Get PDF
    Sexual objectification of women is linked to a variety of negative attitudes and behaviour towards them, including myths about sexual aggression. The aim of the study was to examine the link between myths about sexual aggression and sexual objectification through hostile attitudes towards women. A sample of students and non-students (N = 165) completed a questionnaire that included the Acceptance of Modern Rape Myths about Sexual Aggression Scale, the Interpersonal Sexual Objectification Scale-Perpetrator Version, and a measure of hostility towards women. The results indicated that acceptance of myths about sexual aggression was positively correlated with sexual objectification and hostility towards women. In addition, acceptance of myths about sexual aggression was indirectly related to sexual objectification via hostile attitudes towards women. We discuss the implications of our findings for the relationship between the negative perceptions and treatment of women, particularly those relating to sexualised attitudes and rape myth acceptance

    Adjustment disorder, traumatic stress, depression and anxiety in Poland during an early phase of the COVID-19 pandemic

    Get PDF
    Background: The current COVID-19 pandemic is associated with a variety of stressors. Preliminary research has demonstrated that general public are experiencing a range of psychological problems, including stress-related disturbances. However, to date, there is not much research on the prevalence of adjustment disorder during the current pandemic. Objectives: This study aimed to assess the prevalence and severity of symptoms of adjustment disorder compared to posttraumatic symptoms, depression and generalized anxiety in a large sample of adult Poles, in the first phase of the current pandemic. Method: Self-report data from a web-based sample (N = 1,742) was collected between March 25 and April 27, just after the introduction of nationwide quarantine measures in Poland. Results: The current COVID-19 pandemic was a highly stressful event for 75% of participants and the strongest predictor of adjustment disorder. Increased symptoms of adjustment disorder were reported by 49%, and they were associated with female gender and not having a full-time job. However, after exclusion of co-occurring symptomatology, 14% of the sample were finally qualified as meeting diagnostic criteria of adjustment disorder. A substantial proportion of the sample screened also positive for generalized anxiety (44%) and depression (26%); the rate for presumptive PTSD diagnosis was 2.4%. Conclusions: High rates of negative mental health outcomes were found in the Polish population in the first weeks into the COVID-19 pandemic and lockdown measures. They indicate the intense current stress-related symptoms in the early phase of the pandemic and warrant further monitoring on population’s mental health

    Theory of Mind Performance in Younger and Older Adults with Elevated Autistic Traits

    Little is known about the impact of aging with Autism Spectrum Disorder on theory of mind (ToM). While ToM difficulties appear to abate with age in older autistic populations, this has yet to be explored in the Broad Autism Phenotype (BAP). The current study examined ToM performance among younger (n = 49, aged 18–46) and older adults (n = 47, aged 60–91) who were classified as on the BAP (younger n = 18; older n = 21) or not (younger n = 31; older n = 26) using the BAP Questionnaire. ToM was assessed using the ecologically valid Strange Stories Film Task (SSFT) and the dynamic Happé–Frith Triangle Animations task (TA). A 2 × 2 analysis of variance examined the effects of autistic traits (BAP vs. non‐BAP) and age (young vs. old). For both SSFT and TA, results showed autistic trait main effects on task performance (non‐BAP > BAP). Age main effects were observed for some but not all metrics on TA (younger better than older), with no differences in SSFT. An interaction of autistic traits and age was observed in TA Intentionality, with younger non‐BAP and younger BAP performing similarly but older non‐BAP performing better than older BAP. Results show that younger and older adults with elevated autistic traits show poorer ToM performance. Despite ToM difficulties being common in later life in the general population, this effect was not observed when using a ToM task designed to reflect real‐world scenarios. However, results suggest that autistic traits and age could interact to increase risk for poor ToM performance in older adults who endorse elevated autistic traits

    Social isolation, physical inactivity and inadequate diet among European middle-aged and older adults

    Get PDF
    Social isolation is a growing public health concern for older adults, as it has been associated with poor health and premature mortality. On the other hand, physical inactivity and an inadequate diet are important health risk behaviours associated with physical and mental health problems. Considering that there is no research examining the possible relationship between social isolation and the above mentioned health risk behaviours of European middle-aged and older adults, this cross-sectional study aims to contribute to filling this gap.Fundação Calouste Gulbenkia

    Parental decisions about children's oral health behaviour - relative or absolute?

    Get PDF
    Objectives To test the extent to which parents' judgements about their children's oral health behaviour conform to the principles of a specific theory of cognitive decision making – Range-frequency Theory. Methods Experimental study with an opportunity sample of 121 parents of young children (3–6 years old) living in areas of relative deprivation in South Wales. Parents were allocated to four different experimental groups, and each completed a pen-and-paper exercise, which involved being presented with (and rating) how often other parents brushed their children's teeth. The brushing frequencies presented varied between the groups, directly test the rank and range principle of Range-frequency Theory. Results Parents' ratings of other toothbrushing frequencies were predicted by the range and rank principle of Range-frequency Theory. A comparison between Group 1 and Group 2 showed that parents' ratings of similar brushing frequencies were affected by their relative rank among other brushing frequencies presented. A comparison between Group 3 and Group 4 showed that parents in a group who were presented with a very high brushing frequency (21 times a week) rated all other brushing frequencies as relatively less healthy than the comparison group. Conclusions The principles of Range-frequency Theory predicted parents' judgement about children's oral health behaviour – specifically toothbrushing frequency. These findings provide a theoretical framework on which to develop future oral health education and interventions aimed at promoting twice-daily toothbrushing to parents of young children

    Beck depression inventory, second edition, Czech version : demographic correlates, factor structure and comparison with foreign data

    Get PDF
    Objective: We aimed to examine whether demographic characteristics (i.e., sex, age and education) correlate with total scores of the Czech version of the Beck Depression Inventory (BDI-II), understand the factorial structure of this scale, compare our results with findings of studies conducted in other countries and provide preliminary normative data for use in clinical practice. Methods: Data of 450 participants were analysed using correlation analysis, non-parametric tests and confirmatory factor analysis (CFA). Results: Women, and participants with lower education, tended to score higher than men, and participants with higher education. There was no significant relationship between age and total scores. CFA confirmed two factors: cognitive-affective and somatic. Czech participants scored lower than participants in other studies. Preliminary normative data are presented in the form of percentile values for the whole sample and stratified according to gender and education level. Conclusions: We recommend the usage of the BDI-II total score while taking into account also the cognitive-affective and somatic factor subscores. The comparison of our results with other foreign findings shows the need for the development of locally specific normative values for self-reported depression scales

    Revisiting the Red Effect on attractiveness and sexual receptivity: No effect of the color red on human mate preferences

    Get PDF
    Color-in-Context theory is the first theoretical framework for understanding color effects in human mate preferences, arguing that red clothing enhances attractiveness ratings. Here we present three empirical studies failing to support this prediction. We aimed to extend the current literature by differentiating color effects by temporal context (short-term versus long-term mating). Experiment 1 involved Dutch participants rating a woman in red, white, and black on (sexual) attractiveness. Experiment 2 replicated the first experiment with an American sample. In the final experiment we aimed to replicate a study that did find evidence of a red effect, using a substantially larger sample size. The results from each of the three studies (totaling N= 830 men) fail to support the red effect. We discuss the implications of our results and avenues for future research on red effects and attractiveness
