Negative Numbers are not yet Automatically Associated with Space in 6th Graders

ABSTRACT

The metaphor of the mental number line accounts for numerous empirical effects of spatial-numerical associations. In the present study, we aimed at investigating directional spatial-numerical associations reflected by SNARC-like digit-direction and sign-direction congruency effects as well as the sign-digit compatibility effect when 6^th graders performed magnitude comparisons of multi-symbol numbers (i.e., positive and negative numbers). As spatial-numerical associations were associated with sensorimotor experiences, we used whole-body and finger tapping responses to manipulate the extent of motor responses. We only observed a SNARC-like digit-direction congruency effect, but neither a sign-direction congruency nor a sign-digit compatibility effect. This indicates that 6^th graders may already have developed spatial-numerical associations for absolute number magnitude, but not yet for polarity signs. Furthermore, not observing a sign-digit compatibility effect seemed to suggest that 6^th graders may not yet process multi-symbol numbers in the same parallel componential way as adults do. We argue that while 6^th graders are able to process negative numbers, they are not yet automatically associated with space or integrated in the place-value structure of the Arabic number system like multi-digit numbers are at this age.     

When voices get emotional: A corpus of nonverbal vocalizations for research on emotion processing

Nonverbal vocal expressions, such as laughter, sobbing, and screams, are an important source of emotional information in social interactions. However, the investigation of how we process these vocal cues entered the research agenda only recently. Here, we introduce a new corpus of nonverbal vocalizations, which we recorded and submitted to perceptual and acoustic validation. It consists of 121 sounds expressing four positive emotions (achievement/triumph, amusement, sensual pleasure, and relief) and four negative ones (anger, disgust, fear, and sadness), produced by two female and two male speakers. For perceptual validation, a forced choice task was used (n = 20), and ratings were collected for the eight emotions, valence, arousal, and authenticity (n = 20). We provide these data, detailed for each vocalization, for use by the research community. High recognition accuracy was found for all emotions (86 %, on average), and the sounds were reliably rated as communicating the intended expressions. The vocalizations were measured for acoustic cues related to temporal aspects, intensity, fundamental frequency (f0), and voice quality. These cues alone provide sufficient information to discriminate between emotion categories, as indicated by statistical classification procedures; they are also predictors of listeners’ emotion ratings, as indicated by multiple regression analyses. This set of stimuli seems a valuable addition to currently available expression corpora for research on emotion processing. It is suitable for behavioral and neuroscience research and might as well be used in clinical settings for the assessment of neurological and psychiatric patients. The corpus can be downloaded from Supplementary Materials.     

Anxiety and performance in runners: Effects of stress and anxiety on physical performance

Abstract

The aim of this study was to investigate the effects of state and trait anxiety on physical performance under both neutral and stressful conditions. In Study I, 43 male and female track athletes answered the State-Trait Anxiety Inventory and twice underwent ergometric testing in the physiology laboratory after receiving a neutral or a stress-inducing instruction. In Study II, these 43 runners completed the state scale shortly before a test run in a practice session and once again just before the start in an official competition. Results showed a significant increase in self-reported state anxiety under the stress condition in both the laboratory and the field setting. At the same time, the mean physical performance, measured as physiological performance parameters (maximum oxygen intake, physical work capacity) or as running performance, significantly deteriorated under stress. The induced stress affected the heart rate in addition to the mere physical work load, with no sign of compensation occurring during the entire period of ergometric testing. Effects of anxiety on performance were tested by separate 2(trait) × 3(state) ANOVAs for each situation. For both laboratory situations, and for the practice situation as well, no significant relationships, neither linear nor nonlinear, were detected. In the competition situation, however, an inverted-U relationship was found in the low trait-anxious subgroup.     

Verbal Sexual Coercion Experiences,Sexual Risk,and Substance Use in Women

Research has linked sexual assault, substance use, and sexually transmitted infection (STI) risk in women. Sexual assault by means of verbal sexual coercion (VSC) is more common than sexual assault by means of physical tactics, but VSC is rarely assessed independently. In addition, past work has established global connections among substance use, sexual assault history, and STI risk; however, assessing substance use during sexual behavior is less common. This study examined the relations among VSC, STI risk behavior, and substance use and attitudes. We hypothesized that women with larger numbers of VSC experiences would report more frequent sexual risk behaviors and substance use and attitudes. Participants with larger numbers of VSC experiences reported larger numbers of anal sex partners, more frequent penile–vaginal sex and sexual activity after substance use, and stronger sex-related alcohol expectancies. These findings suggest that VSC is associated with higher levels of STI risk in women.     

“You Should Know Better”: Expressions of Empathy and Disregard Among Victims of Massive Social Trauma

There is a belief that victims of extreme violence should be sensitive to the suffering of others although most of the psychosocial literature points to the opposite. We examine this belief by looking at work that we have carried out on the psychosocial effects of the Holocaust and on the Palestinian-Israeli conflict. We assert that being a victim of collective violence often inhibits empathy toward others and creates continued animosity. We focus on intergenerational aspects connected to victimization and their negative impact on the expression of empathy among descendants of victims in order to explain why the sense of victimhood and justification of repeated violence is often expressed by individuals born years after the original violence took place.     

Spiritual advisors and old age psychiatry in the United Kingdom

This survey investigates the role and views of NHS spiritual advisors across the United Kingdom on the provision of pastoral care for elderly people with mental health needs. The College of Health Care Chaplains provided a database, and questionnaires were sent to 405 registered NHS chaplains/spiritual advisors. The response rate was 59%. Quantitative and qualitative analyses were carried out. Spiritual advisors describe their working patterns and understanding of their roles within the modern NHS, and their observations of the level of NHS staff awareness of the importance of spiritual issues in the mental health care of older adults. They provide insights into possible negative and positive perceptions of their roles at a service level, and contribute suggestions of topics relevant to shared education between pastoral care and clinical services. This survey further highlights ethical and operational dimensions at the point of integration of the work of spiritual advisors and multidisciplinary teams.     

Missed first appointments: Prevalence and associated factors in first-time attendees at an outpatient psychiatric clinic in Nigeria

In Nigeria, outpatient care forms the bulk of the psychiatric service. While there are no published data, empirical observations indicate that default may be high and exerting a huge toll on the cost of care. The aims were to determine the first-appointment default rate among newly seen outpatients in a psychiatric clinic and to identify factors associated with it. The study was a survey of all newly seen patients from 1 January 2006 to 31 January 2006, and who were given a follow-up appointment. A total of 223 new patients were seen. Of these, 151 (67.7%) turned up for their appointment, 61 (27.4%) defaulted, and 11 (4.9%) were referred. Defaulters were more likely to be Christians, younger in age, and in employment. On using correlation statistics, respondents’ religion and occupational status demonstrated a linear relationship and a significant association with follow-up attendance/non-attendance. The rate of non-attendance at first follow-up is of clinical concern, and the possible contribution of religion to this may be enormous. Clinicians and health policy makers need to be sensitive to this. The introduction of community psychiatric services and collaboration between orthodox and traditional/religious practitioners may help reduce default rates.     

“I May Look 75, but I’m Really a Pioneer”: Concept of Self and Resilience Among Israeli Elder Adults Living in a War Zone

This qualitative study explored concept of self and its connection to resilience among 35 elderly Israeli men and women, who live in a war zone along the border with Gaza. The participants were asked to tell their life stories and to answer questions that dealt with hardships they have faced, including the security threat that characterizes the area. Analyses of the interviews revealed 13 overall themes. The major theme discussed in this article centers on the interviewees’ self concept of being ideological pioneers, who have a strong belonging to the settlements they created in the desert. We conclude that this self-concept relates to resilience among this population, in spite of the hardships they have faced on the personal, familial, communal and social-political levels.     

Understanding of and reasoning about object–object relationships in long-tailed macaques?

Diagnostic reasoning, defined as the ability to infer unobserved causes based on the observation of their effects, is a central cognitive competency of humans. Yet, little is known about diagnostic reasoning in non-human primates, and what we know is largely restricted to the Great Apes. To track the evolutionary history of these skills within primates, we investigated long-tailed macaques’ understanding of the significance of inclinations of covers of hidden food as diagnostic indicators for the presence of an object located underneath. Subjects were confronted with choices between different objects that might cover food items. Based on their physical characteristics, the shape and orientation of the covers did or did not reveal the location of a hidden reward. For instance, hiding the reward under a solid board led to its inclination, whereas a hollow cup remained unaltered. Thus, the type of cover and the occurrence or absence of a change in their appearance could potentially be used to reason diagnostically about the location of the reward. In several experiments, the macaques were confronted with a varying number of covers and their performance was dependent on the level of complexity and on the type of change of the covers’ orientation. The macaques could use a board’s inclination to detect the reward, but failed to do so if the lack of inclination was indicative of an alternative hiding place. We suggest that the monkeys’ performance is based on a rudimentary understanding of causality, but find no good evidence for sophisticated diagnostic reasoning in this particular domain.
