句法结构和动词重复对汉语句子口语产生中句法启动效应的影响

研究中采用启动范式和图片描述任务, 利用句法选择比率和句子产生潜伏期的两个指标, 考察了启动句句法结构、动词是否相同和延时对汉语口语句子产生中句法启动效应的影响。结果发现在选择比率上, 句法结构产生的启动效应随延时变化保持稳定, 由启动句和目标句动词相同导致的启动效应的提高量(词汇增强效应)快速衰退, 首次为句子产生过程的句法选择阶段和计划阶段提供了证据。在句子产生潜伏期上, 仅发现启动句和目标句句法结构相同时缩短了句子产生潜伏期, 这可能是由于启动句句法结构激活水平的提高, 使得说话者在目标句产生的句法计划和选择阶段都更快引起的。选择阶段的加工影响句法选择比率, 而选择阶段和计划阶段共同影响了句子产生的潜伏期, 实验结果支持了两阶段竞争理论的观点。     

A longitudinal study: Affective wellbeing,psychological wellbeing,self-efficacy and academic performance among first-year undergraduate students

Students’ mental health have a greatest impact on wellbeing and academic performance, also is often affected adaptation to the university life. This study examines the proportion of students with a positive and negative affect balance, and the relationship between affective wellbeing and academic self-efficacy and performance. It also analyzes how psychological wellbeing and academic self-efficacy predict affective wellbeing and academic performance. In a sample of 200 undergraduate students (M = 19.07 years), it was found that positive affect decreased and negative affect increased during the second academic year. The majority had a positive affect balance (AB). Psychological wellbeing predicts positive emotions and its achievement dimension predicts academic performance. 53% of participating students maintained a positive AB, 14% maintained a negative AB and 21% went from a negative to a positive AB one. The change from a positive to a negative AB (10%) is associated with an increase in psychological wellbeing, suggesting a process of post-stress growth in relation to the challenges of university life.     

Laboratory and questionnaire measures of aggression among female parolees with violent or nonviolent histories

Female parolees were recruited into a laboratory study to determine the relationship between their previous aggression history, questionnaire measures of aggression, and behavioral measures of aggressive responding using a laboratory methodology: the Point Subtraction Aggression Paradigm (PSAP). Subjects were assigned to a violent or nonviolent group based on their criminal history. Subjects participated in sessions in which they were given three response options: (1) nonaggressive responding that earned money, (2) aggressive responding that ostensibly subtracted money from another fictitious person and was defined as aggressive since it resulted in the ostensible delivery of an aversive stimulus (subtraction of money) to another person, and (3) escape responding that protected the subject's earnings from periodic subtractions initiated by the fictitious other person. Results indicated that the violent female parolees emitted significantly more aggressive responses than subjects in the nonviolent group. This study provides additional external validity as well as evidence for convergent and discriminant validity for PSAP laboratory measurement of human aggressive responding and extends these findings to female parolees. Comparisons to previously published data with male parolees showed that gender differences were found among violent but not nonviolent parolees. Aggr.

Visual consciousness of faces in the attentional blink: Knowledge-based effects of trustworthiness dominate over appearance-based impressions

How we perceive and evaluate other persons depends on appearance-based impressions as well as top-down information such as knowledge about someone’s character. To date, little is known about how these two sources of information affect the conscious perception of faces, about their relative contributions and possible interactions. Here, we directly compare how social-affective knowledge and visual cues of trustworthiness impact the access of faces to visual consciousness. Low- and average-trustworthy looking faces were associated with neutral or negative information about a person’s social behavior. Trustworthiness and facial expression ratings showed robust and independent effects of both sources of information during evaluations. Under conditions of reduced attention in an attentional blink task, prioritized detection of faces associated with negative as compared to neutral person knowledge was observed, whereas facial trustworthiness did not affect detection. Thus, while both factors influenced conscious perception and evaluation, only person knowledge impacted the access to consciousness.     

Prosocial behaviour mediates the relation between empathy and aggression in primary school children

ABSTRACT

The negative association between empathy and aggression has been widely investigated in the literature. However, the role of potential mediators and the extent to which their effects are gender-specific have been given considerably less attention. The present cross-sectional study was therefore aimed at examining the direct and indirect relations between empathy (differentiated into perspective taking and empathic concern), prosocial behaviour and aggression in a sample of 240 primary school children between 8 and 12 years of age. The results showed that perspective taking and empathic concern had indirect (rather than direct) negative effects on aggression by enhancing prosocial behaviour. These indirect paths applied equally well to boys and girls, although significant gender differences were observed in empathic concern, prosocial behaviour and aggression. Possible explanations and differences with previous studies are discussed.     

Counter-regulation triggered by emotions: Positive/negative affective states elicit opposite valence biases in affective processing

The present study investigated whether counter-regulation in affective processing is triggered by emotions. Automatic attention allocation to valent stimuli was measured in the context of positive and negative affective states. Valence biases were assessed by comparing the detection of positive versus negative words in a visual search task (Experiment 1) or by comparing interference effects of positive and negative distractor words in an emotional Stroop task (Experiment 2). Imagining a hypothetical emotional situation (Experiment 1) or watching romantic versus depressing movie clips (Experiment 2) increased attention allocation to stimuli that were opposite in valence to the current emotional state. Counter-regulation is assumed to reflect a basic mechanism underlying implicit emotion regulation.     

Fuzzy rough sets: Survey and proposal of an enhanced knowledge representation model based on automatic noisy sample detection

Fuzzy Rough Set (FRS) theory, which has been emerged thanks to unifying Rough Set and Fuzzy Set ones, is a powerful mathematical tool for handling and processing real data of imprecise, incomplete, inconsistent and uncertain nature. It has drawn attention of many researchers, scientists and industrials in various domains over the last three decades. However, different studies have showed that its classical knowledge representation model has a main weakness linked to its sensitivity to data noise which decreases both its effectiveness and application scope. In this paper, we survey the current FRS paradigms developed to deal with this issue and propose a new FRS model based on the Automatic Noisy Sample Detection (ANSD-FRS) able to cope with noise influence in classification tasks. Besides, we study the principal properties of this new model and reformulate the most applied FRS concepts relying on its operators. Numerous experiments have been conducted to analyze the ANSD-FRS behavior compared to the commonly used FRS models reputed as the most noise-resistant paradigms. These experiment results have proved the performance and robustness of the ANSD-FRS in comparison with those renowned models.     

Comprehensive Behavioral (ComB) Treatment of Trichotillomania: A Randomized Clinical Trial

ObjectiveThis study is the first controlled trial of comprehensive behavioral (ComB) treatment of trichotillomania (TTM). ComB provides individualized treatment based on factors triggering and maintaining hair pulling. Method: Participants (N = 36) were adults (M = 34.08 years old, SD = 12.26) meeting DSM5 criteria for TTM. A majority were female (80%) and Caucasian (75%), whereas 17% were African American and 19% Hispanic/Latinx. In a parallel-group design, participants were randomly assigned to (a) Immediate ComB (12 sessions) or (b) Minimal Attention Control (MAC), followed by delayed ComB after week 12. Follow-up continued through week 38. Primary outcomes were self-report (Massachusetts General Hospital Hair pulling Scale; MGH-HPS) and interviewer-rated (NIMH-Trichotillomania Impact Scale and Trichotillomania Severity Scale; TIS/TSS) TTM symptom severity, as well as diagnosis (Trichotillomania Diagnostic Interview).ResultsImmediate efficacy of ComB (vs. MAC) was statistically significant (p = .03) for self-reported symptoms, with an effect size d = −.78, but not significant for interviewer-rated symptoms or diagnostic status. Immediate ComB was significantly more likely than MAC (27% vs. 0%) to lead to complete abstinence from hair pulling at week 12. Follow-ups showed good maintenance of effects.ConclusionsEfficacy of ComB was established for self-reported symptoms. Future research is needed to establish whether the lack of more widespread effects stems from limitations of the model or to a need for more extensive therapist training, as secondary analyses suggested stronger results among therapists with more TTM experience.     

Bidirectional Spillover in the Family across the Transition to Parenthood

Although family systems theory posits reciprocal causality between subsystems of the family, such as intimate partner violence exacerbating harsh parenting and vice versa, longitudinal studies with cross‐lagged models have been used infrequently to test these principles. As guided by the spillover model, this study examined bidirectional associations between couple dysfunction, parent–child aggression risk, and child functioning across the transition to parenthood to determine whether and how disruptions in one subsystem relate to problems in other family subsystems. Participants were 201 first‐time mothers and 151 fathers from a diverse community sample, evaluated during pregnancy, and reassessed two more times through their child's first 18 months of life. Individual and dyadic path model results indicate bidirectional spillover effects between parent–child aggression risk and child functioning for both mothers and fathers, and spillover from parent–child aggression risk to couple dysfunction for mothers but not fathers. However, limited spillover effects were identified between couple functioning and child adjustment, in contrast to previous work. Findings suggest that spillover can happen reciprocally and early in the family, supporting transactional models of behavior and highlighting the need for early family level intervention.
