The positivity scale

Five studies document the validity of a new 8-item scale designed to measure positivity, defined as the tendency to view life and experiences with a positive outlook. In the first study (N = 372), the psychometric properties of Positivity Scale (P Scale) were examined in accordance with classical test theory using a large number of college participants. In Study 2, the unidimensionality of the P Scale was corroborated with confirmatory factor analysis in 2 independent samples (N1 = 322; N2 = 457). In Study 3, P Scale invariance across sexes and its relations with self-esteem, life satisfaction, optimism, positive negative affect, depression, and the Big Five provided further evidence of the internal and construct validity of the new measure in a large community sample (N = 3,589). In Study 4, test-retest reliability of the P Scale was found in a sample of college students (N = 262) who were readministered the scale after 5 weeks. In Study 5, measurement invariance and construct validity of P Scale were further supported across samples in different countries and cultures, including Italy (N = 689), the United States (N = 1,187), Japan (N = 281), and Spain (N = 302). Psychometric findings across diverse cultural context attest to the robustness of the P Scale and to positivity as a basic disposition.

Japanese and British Children's Understanding of the Social Function of Pretend Crying

The purpose of this study was to investigate cross-cultural differences in children's understanding of pretend crying. Five- and 6-year-olds from Japan and the United Kingdom (N = 71) heard two hypothetical stories in which the protagonist of each story pretended to cry in front of another person. Children were asked about the appearance–reality distinction of pretend crying, the other character's thoughts and behavior, and the children's own moral judgment of pretend crying. Cultural differences were found in their understanding of the social function of pretend crying. Japanese children judged that pretend crying elicited another's concern and prosocial behavior more than British children. There were no significant differences in appearance–reality distinction or moral judgments between Japanese and British children. All participants successfully discriminated between pretend crying and real crying, and most participants judged pretend crying as “not good” behavior. These results suggested that Japanese children might be more expected to be sensitive to others’ feelings, and that such cultural differences in communication and socialization lead to different patterns in expectations of the social consequences of pretend crying.     

American-Japanese cultural differences in judgements of emotional expressions of different intensities

Although research has generated a wealth of information on cultural influences on emotion judgements, the information we have to date is limited in several ways. This study extends this literature in two ways, first by obtaining judgements from people in two cultures of expressions portrayed at different intensity levels, and second by incorporating individual level measures of culture to examine their contribution to observed differences. When judging emotion categories in low intensity expressions, American and Japanese judges see the emotion intended at above-chance rates, albeit lower than when judging high intensity faces. Also, American and Japanese intensity ratings of external displays and internal experiences differ dramatically for low intensity expressions compared to high intensity faces. Finally, the two cultural dimensions measured in this study—individualism versus collectivism (IC) and status differentiation (SD)—accounted for almost all of the variance in the observed differences. These findings are discussed in terms of their underlying possible mechanisms, and future research possibilities.     

Participating From the Comfort of Your Living Room: Feasibility of a Group Videoconferencing Intervention to Reduce Distress in Parents of Children With a Serious Illness or Injury

ABSTRACT

This study explored the feasibility and potential effectiveness of a videoconferencing group intervention for parents of children with a life-threatening illness. Parent functioning was assessed at pre, post, and 6-month follow-up (N?=?13). Semistructured interviews explored parent experiences of the program and clinicians’ experiences were systematically recorded. Attendance was high (92%) and parents reported comfort with the online delivery. Quantitative data revealed significant reductions on three of the nine measures examined (parent guilt/worry; unresolved sorrow/anger; lack of psychological flexibility). Clinician data are described and highlights the skills and program modifications required to adapt to the videoconferencing modality. A randomized controlled trial is now underway.     

诱导排尿反射对急性酒精性意识障碍患者催醒作用的研究

为了观察以呋塞米注射液诱导排尿反射对急性酒精性意识障碍患者促醒的作用,将30例急性重度酒精中毒患者纳入观察,随机分为2组,每组15例.两组患者均予补液,营养支持,纠正水电解质、酸碱平衡等对症处理.对照组予注射用纳洛酮2mg,加入5％葡萄糖溶液中静滴,纳洛酮日总用量不超过4.0mg.观察组在对照组基础上,加用呋塞米注射液20mg静脉推注,1次/日.对照组治疗后平均苏醒时间为1.85h±0.26h,观察组治疗后平均苏醒时间为1.28h±0.22h,经t检验,t=6.481 7,P＜0.01,提示观察组疗效优于对照组.笔者认为,以呋塞米注射液诱导排尿反射对急性酒精性意识障碍患者有较好的促醒作用,不仅与促进酒精代谢有关,兴奋觉醒中枢亦是其可能的机制.     

Effort and negative affect interact to predict cardiovascular responses to stress

Objective: Although traditional models posit that negative emotional responses to stress increase cardiovascular reactivity (CVR), laboratory studies have generally not found a strong emotion–CVR association. In this paper, we took a multidimensional approach to examining psychological reactions to stress in three studies.

Methods: In each study we assessed the amount of effort exerted by a participant and the negative affect (NA) felt by the participant with different self-reported measures and an effort behavioural measure.

Results: Our findings consistently demonstrated that NA was associated with CVR when effort was relatively high, but not when effort was relatively low.

Conclusion: This suggests that the weak NA–CVR correlations reported in past research may have been confounded by a third effort-related variable and that CVR is significantly associated with NA under certain circumstances. Furthermore, our findings suggest that by considering the multidimensional nature of psychological responses to stress, we may come to better understand the links between stress-related emotion and physiology.     

Theory of Mind and Sensitivity to Teacher and Peer Criticism Among Japanese Children

This study investigated sensitivity to teacher and peer criticism among 89 Japanese 6‐year‐olds and examined the connection between sensitivity to criticism and first‐order and second‐order theory of mind separately. Participants completed a common test battery that included tasks assessing sensitivity to criticism (teacher or peer condition), the Picture Vocabulary Test—Revised, and theory of mind tasks. The results showed that the children with better understanding of second‐order mental states rated their ability negatively after teacher criticism, but they were motivated to keep trying. This phenomenon was found under only the teacher condition, and peer criticism did not significantly affect children's response, irrespective of theory‐of‐mind level. Cognitive and social factors that may have contributed to the children's responses to criticism are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

Audiovisual tau effect

This study investigated how spatial intervals between successive visual flashes are influenced by the temporal intervals between auditory pure tones presented concurrently with the flashes. Three successive visual flashes defined two spatial intervals with different extents as well as two equal temporal intervals. The onsets of the first and third tones were temporally aligned with those of the first and third flashes, while the onset of the second tone was temporally offset to that of the second visual flash, resulting in shorter or longer temporal intervals between pairs of tones. Observers judged which of the first or second spatial intervals between flashes was shorter. The results showed that the shorter temporal interval between tones caused underestimation of the spatial interval between flashes. On the other hand, stimuli without the first and third tones did not result in underestimation of spatial intervals between flashes. These results indicate an audiovisual tau effect, which is triggered by a constant velocity assumption applied to moving objects defined by more than one modality.

Functional brain activation differences in stuttering identified with a rapid fMRI sequence

The purpose of this study was to investigate whether brain activity related to the presence of stuttering can be identified with rapid functional MRI (fMRI) sequences that involved overt and covert speech processing tasks. The long-term goal is to develop sensitive fMRI approaches with developmentally appropriate tasks to identify deviant speech motor and auditory brain activity in children who stutter closer to the age at which recovery from stuttering is documented. Rapid sequences may be preferred for individuals or populations who do not tolerate long scanning sessions. In this report, we document the application of a picture naming and phoneme monitoring task in 3 min fMRI sequences with adults who stutter (AWS). If relevant brain differences are found in AWS with these approaches that conform to previous reports, then these approaches can be extended to younger populations. Pairwise contrasts of brain BOLD activity between AWS and normally fluent adults indicated the AWS showed higher BOLD activity in the right inferior frontal gyrus (IFG), right temporal lobe and sensorimotor cortices during picture naming and higher activity in the right IFG during phoneme monitoring. The right lateralized pattern of BOLD activity together with higher activity in sensorimotor cortices is consistent with previous reports, which indicates rapid fMRI sequences can be considered for investigating stuttering in younger participants.Educational objectives: The reader will learn about and be able to describe the: (1) use of functional MRI to study persistent developmental stuttering; (2) differences in brain activation between persons who stutter and normally fluent speakers; and (3) potential benefit of time efficient fMRI sequences combined with a range of speech processing tasks for investigating stuttering in younger populations.
