Spatial task performance,sex differences,and motion sickness susceptibility

There are substantial individual differences in susceptibility to motion sickness, yet little is known about what mediates these differences. Spatial ability and sex have been suggested as possible factors in this relationship. 89 participants (57 women) were administered a Motion Sickness Questionnaire that assesses motion sickness susceptibility, a Water-level Task that gauges sensitivity to gravitational upright, and a Mental Rotation Task that tests an individual's awareness of how objects typically move in space. Significant sex differences were observed in performance of both the Water-level Task (p<.01), and the Mental Rotation Task (p<.005), with women performing less accurately than men. Women also had significantly higher scores on the Motion Sickness Questionnaire (p<.005). Among men, but not women, significant negative relationships were observed between Water-level Task performance and Motion Sickness Questionnaire score (p<.001) and between Mental Rotation Task performance and Motion Sickness Questionnaire score (p<.005). In conclusion, women performed significantly more poorly than men did on the spatial ability tasks and reported significantly more bouts of motion sickness. In addition, men showed a significant negative relationship between spatial ability and motion sickness susceptibility.

Relationship of religiosity to mental health literacy,stigma, social distance,and occupational restrictiveness in Ningxia Province,China

Little research has assessed the relationship between religiosity and mental health awareness in low- and middle-income countries. This study identified a representative sample of 2,425 community-dwelling adults in Ningxia, China and administered the Duke University Religion Index, the Mental Health Knowledge Questionnaire, the Mental Health Attitude Questionnaire, the Social Distance – Personal Questionnaire and the Social Restrictiveness – Occupational Questionnaire. Religious affiliation per se was not associated with mental health literacy or attitudes, but higher levels of religiosity were associated with better awareness of mental health issues and less social distance and occupational restrictiveness of those with mental health conditions. However, these relationships were substantially different in Hui ethnicity respondents (85% of whom were practicing Islam) and Han ethnicity respondents (15% of whom practiced Buddhism, Taoism or Confucianism).     

Cross-cultural temperamental differences in infants, children, and adults in the United States of America and Finland

Cross-cultural differences in temperament were investigated between infants (n = 131, 84 Finns), children (n = 653, 427 Finns), and adults (n = 759, 538 Finns) from the United States of America and Finland. Participants from both cultures completed the Infant Behavior Questionnaire, Childhood Behavior Questionnaire and the Adult Temperament Questionnaire. Across all ages, Americans received higher ratings on temperamental fearfulness than Finnish individuals, and also demonstrated higher levels of other negative affects at several time points. During infancy and adulthood, Finns tended to score higher on positive affect and elements of temperamental effortful control. Gender differences consistent with prior studies emerged cross-culturally, and were found to be more pronounced in the US during childhood and in Finland during adulthood.     

Trait anxiety, defensiveness, and the structure of worry

A principal components analysis of the ten scales of the Worry Questionnaire revealed the existence of major worry factors or domains of social evaluation and physical threat, and these factors were confirmed in a subsequent item analysis. Those high in trait anxiety had much higher scores on the Worry Questionnaire than those low in trait anxiety, especially on those scales relating to social evaluation. Scores on the Marlowe-Crowne Social Desirability Scale were negatively related to worry frequency. However, groups of low-anxious and repressed individuals formed on the basis of their trait anxiety and social desirability scores did not differ in worry. It was concluded that worry, especially in the social evaluation domain, is of fundamental importance to trait anxiety.     

Differences between children with attention deficit disorder,children with specific learning disabilities,and normal children

The study investigated the power of five measures to differentiate between children with Attention Deficit Disorder (ADD), children with Specific Learning Disabilities (SLD), and normal children. The measures employed were the Conners Parent Questionnaire (CPQ), the Conners Teacher Questionnaire (CTQ), the Matching Familiar Figures Test (MFFT), the Porteus Mazes Test (PMT), and the Jumbled Numbers Game (JNG). The results indicated that the Conners Parent Questionnaire, Conners Teacher Questionnaire, Matching Familiar Figures Test, and the Porteus Mazes Test significantly discriminated between groups. The Conners Questionnaires were able to discriminate between all three groups and the MFFT and PMT were able to discriminate between ADD and normal children. A discriminant analysis indicated that the CPQ was the best predictor of group membership, followed in order by the CTQ PMT, and MFFT.     

Mobility,Cognitions, and panic

Responses to the Mobility Inventory for Agoraphobia and the Cognitions Questionnaire were compared from samples of agoraphobics, social phobics, senior citizens, students, and students' relatives. The data illustrate the occurrence of avoidant behavior and panic in groups other than agoraphobics. The Mobility Inventory was shown to have good discriminative power, but the Cognitions Questionnaire failed to discriminate between agoraphobics and social phobics. The relationship of panic to mobility and cognitions is considered.     

A Comparison of Effectiveness of Dohsa‐hou and the Alexander Technique on Happiness,Social Adjustment,Hope, Mental Health,and Quality of Life in Patients with Parkinson's Disease

The purpose of this study was to compare the effectiveness of Dohsa‐hou and the Alexander Technique on happiness, social adjustment, hope, mental health, and quality of life in patients with Parkinson's disease. The statistical population of this study included all of the patients with Parkinson's disease who were clients of neural therapeutic centers in Isfahan City in 2015. Among this population, 28 patients were selected through convenience sampling as the sample of the study. The Oxford Happiness Questionnaire, the Social Adjustment Scale, the Adult Hope Scale, the General Health Questionnaire, and the Word Health Quality of Life Questionnaire were used as the instruments of the study. Data were analyzed by analyses of variance with repeated measures. The results showed that both interventions of this study can improve happiness, hope, and quality of life in patients with Parkinson's disease, but Dohsa‐hou is more effective than the Alexander Technique in the improvement of happiness and hope. Probable explanations have been discussed.     

Reports of bodily change in anxiety,sadness, and anger

In a series of studies, retrospective reports were used to assess differences in physiological symptoms associated with three emotions: Anxious, Angry, Sad. Symptom awareness, as measured by scores on the Autonomic Perception Questionnaire and the Somatic Perception Questionnaire, was significantly greater for Anxious than for the other emotions; reports for Angry and Sad were quantitatively similar. Qualitative analysis showed a different pattern. Sad was characterized as involving a low arousal state, while Anxious and Angry shared several distinguishing symptoms, most notably cardiac symptoms and general restlessness. Predicted gender differences were also observed. Males and females did not differ in overall reported level of awareness, but did differ in their reports of the specific symptoms constituting that awareness.     

Memory aberrations, transliminality, and delusional ideation

This study investigated the relationships between cognitive-perceptual personality dimensions (transliminality and delusional ideation) and self-report measures of memory error (Oblivion Scale and the Prospective and Retrospective Memory Questionnaire). 100 full- and part-time psychology undergraduate students completed the measures (18 men and 82 women; M = 19.3 yr., SD = 4.4). A positive correlation was found between transliminality and reported memory aberrations (Oblivion Scale scores) and also between transliminality and Prospective and Retrospective Memory Questionnaire scores. Correlations were positive between Peters, et al. Delusions Inventory and the self-report memory measures. Transliminality and Peters, et al. Delusions Inventory scores predicted the number of memory aberrations or slips reported on the Oblivion Scale and Prospective and Retrospective Memory Questionnaire. To explore whether transliminality explained additional variance to that accounted for by the Peters, et al. Delusions Inventory, forward regression was applied and showed aspects of transliminality not accounted for by Peters, et al. Delusions Inventory did not explain additional variance within the self-report memory measures.     

Handedness, emotional problems, and schizotypy

The purpose of this study was to analyse the relationship between emotional or behavioural problems and schizotypy. An assessment of handedness and schizotypal personality traits were also performed by means of the Thinking and Perceptual Style Questionnaire, the Multidimensional Schizotypal Traits Questionnaire, the Edinburgh Handedness Inventory, and the Youth Self-Report. The sample comprised 296 participants with a mean age of 13.8 and a standard deviation of 1.34. Data indicate that adolescents with high scores on psychometric factors of schizotypy displayed higher patterns of problem behaviours as well as a significant difference in all the core factors of the Youth Self-Report, compared to those who scored low on these measures. Discriminant analysis showed that the core factors of the Youth Self-Report correctly classified 84% of the adolescents with high or low scores on psychometric schizotypy. Lastly, no significant association between the factors of schizotypy and left-handedness, right-handedness, or mixed-handedness was found.

Hardy personality, self-efficacy, and general health in nursing professionals of intensive and emergency services

In this study, the predictive power of hardy personality and generalized self-efficacy on general health perception was investigated in a sample of nursing personnel working in emergency and intensive care services. A cross-sectional retrospective design was used, and the following measurement instruments were applied: a sociodemographic and work questionnaire, Goldberg's GHQ-28 Health Questionnaire, the Baessler and Schwarzer General Self-efficacy Questionnaire, and the Hardy Personality Subscale of Moreno's Nursing Burnout Questionnaire (CDPE). The results revealed a positive and statistically significant relationship between the individual variables of generalized self-efficacy and hardy personality. A canonical correlation analysis carried out on the psychological distress symptoms with self-efficacy and hardy personality as predictor variables, led us to emphasize the relevance of the construct total hardy personality as a predictor and, consequently, as a protective factor against the onset of psychological distress symptoms in the sample of professionals studied. Lastly, the implications of the results for clinical practice are discussed.     

Authentic leadership,psychological capital,job satisfaction and intention to leave in state-owned enterprises

This study investigated the relations among authentic leadership, psychological capital, job satisfaction and intention to leave within state-owned enterprises in Namibia. Participants were a convenience sample of 452 employees (females?=?49.6%, mean age?=?37.36, SD?=?8.57) state-owned enterprises in Namibia. They completed the Authentic Leadership Questionnaire, Psychological Capital Questionnaire, Job Satisfaction Questionnaire and Turnover Intention Scale. Structural equation modelling was utilised to investigate the relations among authentic leadership, psychological capital, job satisfaction and intention to leave. The findings indicated that authentic leadership was positively associated with psychological capital (i.e. experiences of hope, optimism, self-efficacy and resilience) and job satisfaction. Authentic leadership affected job satisfaction indirectly via psychological capital. Psychological capital had a medium to large indirect effect on employees' intentions to leave. The findings suggest that authentic leadership and psychological capital explain job satisfaction and retention of employees in state-owned enterprises.     

Psychological,physical, and interpersonal correlates of emotional expressiveness,conflict, and control

This article examines the relations between emotional expression, conflict over expression, and emotional control and psychological and physical distress. Fifty married couples completed two mail-in surveys containing the Emotional Expressiveness Questionnaire (EEQ), the Ambivalence Over Emotional Expression Questionnaire (AEQ), and the Emotional Control Questionnaire (ECQ), as well as measures of psychological and physical well-being. They also made expressiveness and well-being ratings of their spouses. AEQ and ECQ scores were significantly positively correlated with measures of psychological distress and questionnaire measures of physical discomfort. In addition, AEQ scores for items dealing explicitly with anger predicted visits to health-care provider for illness. EEQ scores did not predict either psychological distress or physical symptoms. AEQ scores were also positively correlated with spouse's symptoms and alcohol use. Wives' expressiveness ratings for their husbands were negatively correlated with a number of indices of psychological distress, while husbands' ratings of wives' expressiveness were positively correlated with measures of distress. Generally, expressiveness, inhibition, and conflict over expression in one spouse did not consistently predict well-being of the other. Implications of these findings for future research in the area of emotion and illness as well as in relationship satisfaction are discussed.     

Factor structure,validity, and reliability of the fear questionnaire in a Hong Kong Chinese population

This study examined the factor structure, validity, and reliability of the Fear Questionnaire in Hong Kong. The sample consisted of 226 college students who were ethnic Chinese and they came from different parts of Hong Kong. Exploratory factor analysis produced three meaningful factors. Confirmatory factor analysis supported the three-factor model of Marks and Mathews (1979) in the present sample of subjects. Findings also showed that the Fear Questionnaire was both reliable and valid. Limitations of the study and implications for future research in this area were discussed. In particular, the need to assess the cross-cultural application of the Fear Questionnaire was stressed.This research project was supported by the Research and Conference Grants of the University of Hong Kong.     

Relationships between experiences, processing style, and sex-related differences in performance on spatial tests

53 female and 45 male undergraduates were administered the Spatial Antecedents Questionnaire (Activities, Academic Courses, Self-assessments, and Environmental Mapping subscales), the Spatial Dimensionality Test (Embedded Figures, Card Rotations, Paper Folding, Surface Development, Horizontal/Vertical Rotations, and Cube Perspectives subtests), and Revised-Individual Differences Questionnaire of Paivio. Scores from the Academic Courses and Self-assessment scales accounted for the most variability in spatial performance. Visual processing style correlated with performance on spatial tests for men, but not for women. Different patterns of activities and experiences correlated with spatial test performance for men and women.
