The effect of feature discriminability on the intertrial inhibition of focused attention

Identifying the shape of a colour oddball is faster when the distractor colour is viewed in the preceding target-absent trial and slower when the target colour is previewed, an intertrial effect known as the distractor previewing effect (DPE). We tested the effect of feature discriminability on the DPE. In Experiment 1, we determined the interitem discriminability of two colour pairs and two shape pairs. In Experiments 2 and 3, we measured DPEs with these set of target–distractor discriminability pairs. Our results showed that when the defining features allow for efficient parallel search, the a priori degree of interitem discriminability did not modulate the DPE. The results suggest the DPE does not arise as a strictly bottom-up modulation of saliency of the search-relevant features but reflects an attentional bias aimed at preventing attention from revisiting recently rejected “search features”. The underlying mechanism of this attentional bias is discussed.     

Relationship Between Mother,Father, and Peer Attachment and Empathy With Moral Authority

We explored the relationship between mother, father, and peer attachment security, empathy, and moral authority in order to clarify certain problems of previous empirical research on such relationships. A sample of 202 Persian-speaking undergraduate students completed questionnaires pertaining to these constructs. The results revealed that mother and father attachment were significantly correlated with family, society welfare, and equality sources of moral authority, whereas peer attachment security was related only to society welfare and equality sources of moral authority. Out of the empathy subscales, only empathic concern was associated with moral authority sources. Empathic concern was also related to mother, father, and peer attachment, whereas perspective taking was correlated with mother and peer attachment. The combination of empathic concern and mother, father, and peer attachment predicted significant amount of variance of “principle source of moral authority” (including society welfare and equality sources). Findings support existence of a strong relationship between attachment security and the content of moral thought of adolescents, and findings redress an empirical imbalance in research literature on the relation of attachment and morality.     

青少年人际压力、人际自我效能感与社交适应行为的关系

采用《青少年社会适应量表》、《青少年人际压力量表》和《青少年人际交往自我效能感问卷》对916名中学生进行施测,探讨青少年人际压力、人际自我效能感与社交适应行为之间的关系以及人际自我效能感在其中所起的作用。结果表明,人际压力与人际自我效能感、社交适应行为之间均存在显著负相关,人际自我效能感与社交适应行为呈显著正相关;人际自我效能感在青少年同伴压力、家庭环境压力与社交适应行为关系之间起着部分中介作用。     

父母早期受虐与子女对立违抗症状的关系:亲子虐待和儿童愤怒管理的作用

本研究探讨了父母的早期受虐经历与子女的对立违抗症状的关系,通过构建一个有调节的中介模型,考察了亲子虐待的中介效应和儿童愤怒管理对该效应的调节作用。采用问卷法对359名来自北京市、山东省和云南省的14所小学一至五年级的儿童及其父母进行调查,研究工具包括儿童对立违抗症状评估表、童年期创伤问卷、儿童愤怒管理量表。结果发现：（1）男孩的ODD症状得分显著高于女孩;男孩受到的躯体虐待、情感忽视和躯体忽视显著多于女孩（2）在控制了儿童性别后,父母在童年期的受虐经历仍可显著正向预测其成年期的家庭中子女的ODD症状;（3）亲子虐待在父母受虐和子女ODD症状之间起完全中介作用,即父母受虐通过亲子虐待间接影响子女ODD症状;（4）父母受虐通过亲子虐待影响子女ODD症状的中介效应后半路径受到子女个体水平愤怒失调（AD）的调节,具体来说,当AD水平较高时,亲子虐待对ODD症状的影响更大;但愤怒应对（AC）和愤怒抑制（AI）对中介效应无显著调节作用。     

Happy Family Kitchen: Behavioral Outcomes of a Brief Community-Based Family Intervention in Hong Kong

Positive psychology interventions commonly involve behavioral exercises to improve psychosocial well-being. Intervention effect on behavior is unclear. The Happy Family Kitchen project, one of the community-based brief intervention projects under The FAMILY: A Jockey Club Initiative for a Harmonious Society, was conducted in Hong Kong to develop and evaluate the effectiveness of a positive psychology family intervention. We have previously reported positive intervention effects on family communication, family well-being, and subjective happiness. This paper aims to explore the effectiveness of the intervention on behavioral outcomes and their associations with psychosocial well-being. A total of 23 social service units organized and conducted intervention programs for 1419 individuals from 612 families in Hong Kong. Each intervention was developed with emphasis on one of five positive psychology themes: gratitude, flow, happiness, health, and savoring. Intervention outcomes were assessed at pre-intervention, immediate post-intervention, and 6 weeks and 12 weeks post-intervention. Results showed that family communication time and frequency of meal preparation with family members increased with sustainable small effects up to 12 weeks. Theme-specific behavior change was observed in the gratitude, flow, and happiness interventions, respectively. Family communication time, frequency of eating with family members, and theme-specific behaviors, including gratitude, flow, happiness behavior, health attitude, and health behavior, were positively associated with psychosocial well-being. Qualitative data provided additional evidence of effectiveness with in-depth insights into behavior change. The positive associations between target behaviors and well-being suggest that improvements in well-being as a function of the intervention may be associated with behavior change.     

Repetition benefit in mental rotation is independent of stimulus repetition

In this study, we investigated whether there is a repetition benefit in mental rotation that is independent of stimulus repetition (i.e., due to increased efficiency in postencoding processing). Three experiments were conducted, in which different conditions of stimulus repetition (different letters on consecutive trials in Experiment 1, letters of different orientations on consecutive trials in Experiment 2, and priming of rotation direction in Experiment 3) were used, and the extent of repetition of rotation direction between two consecutive trials was manipulated. The results of all three experiments showed clear evidence of a repetition benefit without repeating the stimulus, suggesting that this effect is independent of stimulus repetition and lending support to the notion of increased efficiency in mental rotation as a result of repeated rotation direction per se.     

Attachment, borderline personality, and romantic relationship dysfunction

Previous studies have implicated attachment and disturbances in romantic relationships as important indicators for Borderline Personality Disorder (BPD). The current research extends our current knowledge by examining the specific associations among attachment, romantic relationship dysfunction, and BPD, above and beyond the contribution of emotional distress and nonromantic interpersonal functioning in two distinct samples. Study 1 comprised a community sample of women (N = 58) aged 25-36. Study 2 consisted of a psychiatric sample (N = 138) aged 21-60. Results from both Study 1 and Study 2 demonstrated that (1) attachment was specifically related to BPD symptoms and romantic dysfunction, (2) BPD symptoms were specifically associated with romantic dysfunction, and (3) the association between attachment and romantic dysfunction was statistically mediated by BPD symptoms. The findings support specific associations among attachment, BPD symptoms, and romantic dysfunction.     

Loneliness and Suicidal Risk in Young Adults: Does Believing in a Changeable Future Help Minimize Suicidal Risk Among the Lonely?

This study examined loneliness and future orientation as predictors of suicidal risk, namely, depressive symptoms and suicide ideation, in a sample of 228 college students (54 males and 174 females). Results of regression analyses indicated that loneliness was a significant predictor of both indices of suicidal risk. The inclusion of future orientation was found to significantly augment the prediction model of both depressive symptoms and suicide ideation, even after accounting for loneliness. Noteworthy, beyond loneliness and future orientation, the Loneliness × Future Orientation interaction term was found to further augment both prediction models of suicidal risk. Consistent with the notion that future orientation is an important buffer of suicidal risk, among lonely students, those with high future orientation, compared to low future orientation, were found to report significantly lower levels of depressive symptoms and suicide ideation. Some implications of the present findings for studying both risk and protective factors associated with suicidal risk in young adults are discussed.
