Roughness Perception

This study investigated the relationship between median frequency levels and roughness perception for jittered stimuli. Five median frequency levels were combined with four jitter excursions to form stimuli which were submitted to 32 listeners, who judged roughness by paired comparisons, rating scale, and magnitude estimation techniques. The results showed the same trends in each of the procedures. Stimuli of lower median frequency were judged to be rougher than those of higher median frequency, for all jitter conditions. The conclusion is that the median frequency levels of jittered wavetrains do affect the perception of roughness in analog stimuli. Whether the same relationship holds for human rough voices must be experimentally verified.

The Relationship

Manual wheelchair use may determine shoulder joint overload and rotator cuff injury. Chronic shoulder pathologies can also influence the propulsion ability of wheelchair athletes with spinal cord injury (SCI) during sport activities. However, the relationship between shoulder pathology and wheelchair performances has never been explored. Therefore, the study aimed to investigate the correlation between shoulder pathologic findings with clinical tests and ultrasonography evaluation and the results of wheelchair performance tests. Nineteen quadriplegic wheelchair rugby players were evaluated to investigate the association between clinical and ultrasound shoulder pathologic findings and their correlation with the performance of field-based selected wheelchair skills tests (WSTs). The outcome measures were the International Wheelchair Rugby Classification Score, dominant and non-dominant Physical Examination Shoulder Score, and dominant and non-dominant Ultrasound Shoulder Pathology Rating Scale (USPRS). The WST was measured at the beginning and at one-year follow-up. A statistically significant correlation was found between the time since SCI and dominant USPRS (p < 0.005). The non-dominant USPRS was strongly related to WST at the beginning (p < 0.005) and the end of the study (p < 0.05). Data suggest that the severity of the non-dominant shoulder pathology detected on the ultrasound is related to lower performance on the WST. Chronic manual wheelchair use could be responsible for dominant SCI shoulder joint and rotator cuff muscle damage, while non-dominant USPRS could be related to performance on the WST.

The Relationship

The aim of this research is to analyze the relationship between executive functions and adaptive behavior in girls with Fragile X syndrome (FXS) in the school setting. This study is part of a larger investigation conducted at the Hospital Parc Tauli in Sabadell. The sample consists of a total of 40 girls (26 with FXS and 14 control) aged 7–16 years, who were administered different neuropsychological tests (WISC-V, NEPSY-II, WCST, TOL) and questionnaires answered by teachers (ABAS-II, BRIEF 2, ADHD Rating Scale). The results show that there is a greater interaction between some areas of executive function (cognitive flexibility, auditory attention, and visual abstraction capacity) and certain areas of adaptive behavior (conceptual, practical, social, and total domains) in the FXS group than in the control group. These results suggest that an alteration in the executive functions was affecting the daily functioning of the girls with FXS to a greater extent.

Fallacious Reasoning

Informal reasoning fallacies belong to a persuasive tactic, leading to a conclusion that is not supported by premises but reached through emotions and/or misleading and incomplete information. Previous research focused on the ability to recognize informal reasoning fallacies. However, the recognition itself does not necessarily mean immunity to their influence on decisions made. An experiment was designed to study the relationship between the presence of informal reasoning fallacies and a consequent decision. Having conducted paired comparisons of distributions, we have found some support for the hypothesis that informal reasoning fallacies affect decision-making more substantially than non-fallacious reasoning—strong support in the case of a slippery slope, weak in that of appeal to fear, anecdotal evidence argument defying evaluation. Numeracy and cognitive reflection seem to be associated with higher resistance to the slippery slope, but do not diminish appeal to fear.

Abstract Introduction Stress has been identified as a barrier to engaging in positive health behaviors. Sleep interventions, including sleep hygiene recommendations, highlight stress management as an important treatment component. However, the relationship between negative emotion, stress management or emotion regulation, and positive sleep behaviors has largely been unexamined. Therefore, the current study, through secondary analyses, examined the relationships between negative affect, stress and emotional reactivity and sleep incompatible behaviors. Lastly, the indirect effect that dispositional mindfulness, as a possible self-regulatory mechanism, may have on the relationship was also examined. It was hypothesized that greater levels of stress, emotional reactivity, and negative arousal along with lower levels of dispositional mindfulness would predict higher engagement in sleep incompatible behaviors. Methods Participants (n=308) identified mostly as female (55.8%) and White/Caucasian (83.2%) and with an average age of 36.76 (SD = 12.20). Participants completed the Perceived Stress and Reactivity Scale (PSRS), the Positive and Negative Affect Scale (PANAS), the Sleep Behaviors Self-Rating Scale, and the Five Facet Mindfulness Questionnaire (FFMQ). A multiple regression analysis was conducted using the relevant subscales from the PSRS, PANAS, and FFMQ to predict the occurrence of behaviors incompatible with healthy sleep. Results The hypothesis was partially supported. Results indicated that the model significantly predicted sleep incompatible behavior (R2= .108, F(9, 299) = 4.042, p &lt; .001), with only negative affect (β= .163, t(299) = 2.555, p = .011) and nonreactivity (β= -.219, t(299) = -2.484, p = .014) remaining significant when all variables were entered in the model. Conclusion The findings demonstrate that negative affect and reactivity are significant predictors of engagement in poor sleep hygiene practices. They also suggest that certain facets of dispositional mindfulness has an indirect relationship with sleep incompatible behaviors. The results may contribute to the development of sleep health interventions and highlight the need for future research. Support N/A

The Relationship

Recently, the relationship between emotional arousal and depression has been studied. Focusing on this relationship, we first developed an arousal level voice index (ALVI) to measure arousal levels using the Interactive Emotional Dyadic Motion Capture database. Then, we calculated ALVI from the voices of depressed patients from two hospitals (Ginza Taimei Clinic (H1) and National Defense Medical College hospital (H2)) and compared them with the severity of depression as measured by the Hamilton Rating Scale for Depression (HAM-D). Depending on the HAM-D score, the datasets were classified into a no depression (HAM-D < 8) and a depression group (HAM-D ≥ 8) for each hospital. A comparison of the mean ALVI between the groups was performed using the Wilcoxon rank-sum test and a significant difference at the level of 10% (p = 0.094) at H1 and 1% (p = 0.0038) at H2 was determined. The area under the curve (AUC) of the receiver operating characteristic was 0.66 when categorizing between the two groups for H1, and the AUC for H2 was 0.70. The relationship between arousal level and depression severity was indirectly suggested via the ALVI.

Aims: To investigate, in a group of subjects at an early stage of cognitive impairment, the relationship between anosognosia and both cognitive and behavioral symptoms by exploring the various domains of insight. Methods: One hundred and eight subjects affected by cognitive impairment were consecutively enrolled. The level of awareness was evaluated by means of the Clinical Insight Rating Scale (CIRS). Psychiatric symptoms were evaluated using the Italian version of the Neuropsychiatric Inventory (NPI), whereas memory (memory index, MI) and executive (executive index, EI) functions were explored using a battery of neuropsychological tests and qualified by means of a single composite cognitive index score for each function. Results: A significant positive correlation between the total NPI score and global anosognosia score was found. Furthermore, both the MI and EI scores were lower in subjects with anosognosia than in those without anosognosia (p < 0.001 and p < 0.007, respectively). When the single domains of the CIRS were considered, anosognosia of reason of visit correlated with the EI score (r = -0.327, p = 0.01) and night-time behavioral disturbances (r = 0.225; p = 0.021); anosognosia of cognitive deficit correlated with depression (r = -0.193; p = 0.049) and the MI score (r = -0.201; p = 0.040); anosognosia of functional deficit correlated with the MI score (r = -0.257; p = 0.008), delusions (r = 0.232; p = 0.015) and aberrant motor behavior (r = 0.289; p = 0.003); anosognosia of disease progression correlated with the MI score (r = -0.236; p = 0.015), agitation (r = 0.247; p = 0.011), aberrant motor behavior (r = 0.351; p = 0.001) and night-time behavioral disturbances (r = 0.216; p = 0.027). Conclusions: Our study suggests that, in the early stage of cognitive impairment, anosognosia is associated with both cognitive deficits and behavioral disorders according to the specific functional anatomy of the symptoms.

Many researchers agree that virtue is an important psychological concept in contemporary psychology. The main purpose in this study was to investigate the relationship between virtues and the personality traits of college students in mainland China. Participants (N = 426) completed the Chinese Virtue Adjectives Rating Scale (CVARS; Mu, 2007) and the Chinese 16PF (Zhu & Dai, 1988). The results indicated that the 16 personality factors most closely related to the virtue factors were emotional stability, dominance, liveliness, rule-consciousness, social boldness, sensitivity, vigilance, abstractedness, apprehension, self-reliance, perfectionism, and tension. Second-order factors of the 16PF most strongly related to the virtue factors were anxiety, extraversion, tough-mindedness, and independence.

Collection Methods

Destination image is among the most studied constructs in tourism research. Many researchers are still convinced that the rating scale method is the most accurate for assessing destination image. This study presents alternative methods of data collection, namely, free-sorting and reduced paired comparisons, and investigates their applicability in a Web-based environment. The study then subjects these data collection methods to empirical analysis and compares the judgment task’s effects on perceived difficulty, fatigue, and boredom, on data quality, and on perceptual maps derived with MDS. The findings demonstrate that these methods are more accurate whenever a large number of objects have to be judged, which is particularly the case for positioning and competitiveness studies.

The underlying basis for the process-reactive classification is unclear, although some authors offer differences in psychological differentiation as an explanation. This study examined the relationship between the degree of differentiation of the body concept and the process-reactive continuum, which was measured by the Prognostic Rating Scale and the subsequent total number of nights of hospitalization over a 3-yr. period for 51 Ss. There was no significant relationship—linear or curvilinear—between these variables in this sample of acute schizophrenics in whom drug ingestion, chronicity, and length of current hospitalization were controlled.
