Dual-learning systems during speech category learning

Dual-system models of visual category learning posit the existence of an explicit, hypothesis-testing reflective system, as well as an implicit, procedural-based reflexive system. The reflective and reflexive learning systems are competitive and neurally dissociable. Relatively little is known about the role of these domain-general learning systems in speech category learning. Given the multidimensional, redundant, and variable nature of acoustic cues in speech categories, our working hypothesis is that speech categories are learned reflexively. To this end, we examined the relative contribution of these learning systems to speech learning in adults. Native English speakers learned to categorize Mandarin tone categories over 480 trials. The training protocol involved trial-by-trial feedback and multiple talkers. Experiments 1 and 2 examined the effect of manipulating the timing (immediate vs. delayed) and information content (full vs. minimal) of feedback. Dual-system models of visual category learning predict that delayed feedback and providing rich, informational feedback enhance reflective learning, while immediate and minimally informative feedback enhance reflexive learning. Across the two experiments, our results show that feedback manipulations that targeted reflexive learning enhanced category learning success. In Experiment 3, we examined the role of trial-to-trial talker information (mixed vs. blocked presentation) on speech category learning success. We hypothesized that the mixed condition would enhance reflexive learning by not allowing an association between talker-related acoustic cues and speech categories. Our results show that the mixed talker condition led to relatively greater accuracies. Our experiments demonstrate that speech categories are optimally learned by training methods that target the reflexive learning system.     

Revisiting letter transpositions within and across morphemic boundaries

Early morphological decomposition of complex words has been supported by evidence showing that the magnitude of masked transposed-letter (TL) priming effects is greater for within-morpheme transpositions than for between-morpheme transpositions. However, these findings have lately been called into question, and a recent article by Sánchez-Gutiérrez and Rastle (Psychonomic Bulletin & Review, 20, 988–996, 2013) suggested that the above-mentioned interaction could have been the consequence of a false positive (i.e., a Type I error). Considering recent evidence showing that morpho-orthographic interactions are highly sensitive to individual differences in reading skills, we explored whether participants’ averaged reading speeds were responsible for modulating the size of within- versus between-morpheme TL priming effects. A large-scale lexical decision experiment with a set of 420 suffixed Spanish words (N = 80 participants) was run using the masked-priming technique. The results revealed that individual differences modulated the magnitude of the masked TL priming effect between morphemes: Faster readers (but not slower readers) yielded greater TL priming for within- than for between-morpheme transpositions. The present data help reconcile previous divergent data by showing that faster readers revealed a morpho-orthographic interaction, whereas slower readers may rely more on a morphological-processing strategy that is not sensitive to morpho-orthographic interactions.     

Factors Impacting the Mental Health of the Caregivers of Children with Asthma in China: Effects of Family Socioeconomic Status,Symptoms Control,Proneness to Shame,and Family Functioning

Caregiver mental health is widely considered to be an important factor influencing children's asthma symptoms. The present study aimed to examine key factors that contribute to caregiver mental health in pediatric asthma with a Chinese sample. Two hundred participants reported their family socioeconomic status (SES), proneness to shame, asthma symptoms control of their child, family functioning, and their depression and anxiety symptoms. Results suggested that low family SES, low family functioning, and a high level of shame proneness were associated with high levels of anxiety and depression for caregivers. Family functioning mediated the effects of SES and shame on caregiver mental health and also moderated the effects of SES and shame on caregiver depression. This study highlights the importance of reducing experience of shame and enhancing family functioning in families affected by pediatric asthma.     

On Pretabular Logics in NExtK4 (Part II)

In this paper we prove the pretabularity criteria for the logics of infinite depth in NExtK4. Then we use the criteria to resolve the problems of pretabular logics in NExtQ4 and prove that there is a continuum of pretabular logics in NExtQ4 just like NExtK4.

Systemic lupus erythematosus is associated with negatively variable impacts on domains of sleep disturbances: a systematic review and meta-analysis

Sleep disturbances are common in systemic lupus erythematosus (SLE), but the features of sleep disturbances are not well understood. The aim of this study was to identify the impact of SLE on specific sleep quality domains and to determine its prevalence and associations. We performed a systematic review and meta-analysis to compare the sleep outcomes of individuals with SLE and healthy controls. PubMed, MEDLINE, EMBASE, Cochrane Library, Web of Science CNKI, VIP, CNKI and Wanfang database were searched to find the published literatures (from these databases established to May 2017). Studies were screened according to inclusion and exclusion criteria and the qualities of included studies were evaluated. The data was analyzed using Revman5.3 software. Score of the Pittsburgh Sleep Quality Index (PSQI) scoring system was used as the outcome measurement, and mean differences (MD) with 95% confidence intervals (CI) were calculated. Five studies were included, including 350 SLE and 1396 healthy controls. A total of 5 studies including 827 patients were eligible for inclusion in the systematic review and meta-analysis. In this meta-analysis, each domain of the PSQI score: subjective sleep quality (MD, .58; 95% CI, .26, .89), sleep latency(MD, .47; 95% CI, .21, .73), sleep duration (MD, .36; 95% CI, .13, .58), habitual sleep efficiency (MD, .58; 95% CI, .32, .84),sleep disorders (MD, .56; 95% CI, .34, .77), use of sleep medication (MD, .56; 95% CI, .33, .80), daytime dysfunction (MD, .57; 95% CI, .11, 1.04) and the global score (MD, 3.59; 95% CI, 1.37, 5.80) were higher in SLE women than healthy controls. Furthermore, subjective sleep quality and habitual sleep efficiency were most severely affected especially. It demonstrated that targeted interventions should be done to improve their sleep quality. Early recognition and appropriate intervention are essential to reduce the negative impact of sleep disturbances on the patient’s sleep quality and outcome of their disease.     

组织政治氛围对员工疏离感的影响：自我决定动机的中介作用

验证组织政治氛围对员工疏离感的作用,探讨自我决定动机在二者间的中介作用。研究采用一般政治行为知觉量表、工作内外动机量表和工作疏离感量表对226名企事业单位的员工进行问卷调查。研究表明,组织政治氛围对员工疏离感的个人疏离和社会疏离均具有显著的预测作用;自我决定动机在组织政治氛围与员工的个人疏离感之间起部分中介的作用,但在组织政治氛围与员工的社会疏离感之间的中介作用不显著。这说明我国员工的个人疏离感一部分来自于组织政治氛围对员自我决定动机的削弱,而社会疏离感主要来自于组织政治氛围的直接影响。     

Mothers' Ideal Positive Affect Predicts their Socialization of Children's Positive Affect

Parents generally want their children to be happy, but little is known about particular types of positive affect (PA) that parents want their children to experience. Tsai's (2007) affect valuation theory offers a useful framework to understand how parents' emotional goals may shape the socialization of particular types of PA (e.g., excitement vs. relaxation). Participants were 96 mothers and their 7- to 12-year-old children. Results indicated that mothers endorsed similar levels of ideal PA (IPA) for low-, moderate-, and high-arousal PA for both themselves and for their child, suggesting that mothers desire the same type of PA for their children as they want for themselves. In support of the study's main hypothesis, mothers' IPA for their children predicted specific socialization responses that would encourage that type of PA (e.g., mothers' high-arousal IPA predicted greater encouragement of their child to celebrate, whereas mothers' low-arousal IPA predicted encouragement of affection). The findings extend affect valuation theory and emotion socialization research by indicating that parents' emotional goals (i.e., IPA) for their children may contribute to their socialization of children's PA.     

Psychiatric Distress and Suicidal Tendencies in Adult Cancer Survivors: Verifying the Validity of the Brief Symptom Inventory-18 for Identifying Suicidal Ideation in the Hospitalized Population of Mainland China

The Brief Symptom Inventory-18 (BSI-18) is widely used to assess psychiatric distress but has not been verified in the Chinese population. From March to April 2019, 293 hospitalized cancer patients, aged 20–87, completed the cross-sectional survey with demographics questionnaire, BSI-18, and PHQ-9. We analyzed the single suicide-related item of PHQ-9 with the full score clinical outpoint for BSI-18 and PHQ-9 using SPSS 22.0 and R 2.15, including Pearson's χ² test and ROC curve analyses. A Pearson's χ² test was carried out to compare the three different methods with the gold screening criteria. The p-value was correspondingly to .006, .066, .838. When the PHQ-9?≥?10 criteria for the BSI-18, receiver operating characteristic analysis revealed that AUC values were 0.839, optimal cut-off points for both BSI-18?≥?50, the sensitivity of 85.8%, and 62.5%, respectively. The BSI-18 is suitable for a screening tool for psychological distress and could also be used in clinical settings for preliminary screening of hospitalized cancer patients.
