词汇的获得年龄效应:ERP研究

采用听觉呈现条件下的词汇判断任务和ERP技术探讨了汉语双字词获得年龄效应。结果发现:1)在行为数据上,同晚获得词相比,早获得词的反应时更短且错误率更低。2)在ERP数据上,早获得词和晚获得词所诱发的LPC(800m s~1000m s)的平均波幅存在显著差异,同晚获得词相比,早获得词所诱发的LPC波幅更大,且这种差异主要是在中央顶区,说明获得年龄是影响汉语双字词识别的一个重要因素,获得年龄效应出现在认知加工进程的后期。     

Early maturation of frequency-following responses to voice pitch in infants with normal hearing

Neural plasticity of pitch processing mechanisms at the human brainstem, as reflected by the scalp-recorded frequency-following response (FFR) to voice pitch, has been reported for normal-hearing adults. Characteristics and maturation of such a response during the first year of life have remained unclear. The purpose of this study was to examine the characteristics of FFR to voice pitch in normal-hearing infants and to make a direct comparison with adults using the same stimulus and recording parameters. 9 infants and 9 adults were recruited. A Chinese monosyllable that mimics the English vowel /i/ with a rising pitch was used to elicit the FFR to voice pitch. The results demonstrated that infant FFRs showed slightly larger Pitch Strength but comparable Frequency Error, Slope Error, and Tracking Accuracy to those obtained from adults. Early maturation of FFRs was also observed in the infants starting from 1 to 3 mo. of age.     

Internet-delivered physical activity intervention for college students with mental health disorders: a randomized pilot trial

The prevalence of mental health disorders among college students is rising and the increasing rates of anxiety and depression have important societal implications. Physical activity has been proposed as an adjuvant to traditional treatment approaches (i.e. psychotherapy or pharmacotherapy), and the internet is a potentially useful means of delivering physical activity information to the college-aged population. This randomized pilot trial examined the effects of an internet-based physical activity intervention on physical activity, self-efficacy, depression, and anxiety in college students (n?=?47) receiving mental health counseling. Physical activity, depression, anxiety, exercise self-efficacy, and barriers self-efficacy were assessed at baseline and post-intervention. There was a significant time effect for physical activity, with both groups increasing their physical activity levels across the 10-week intervention but with a larger increase in the intervention condition (d?=?0.68) than the control condition (d?=?0.05). Exercise and barriers self-efficacy declined across the intervention, but more so in the control than intervention condition. Effects on depression and anxiety were nonsignificant. Finally, correlation analyses showed increases in physical activity were associated with increases in exercise self-efficacy (r?=?0.62) and barriers self-efficacy (r?=?0.63) and decreases in depression (r?=?-0.44) in the intervention condition, but not in the control condition. These results suggest that an internet-delivered physical activity intervention may be a promising approach to promoting physical activity among college students undergoing mental health counseling.     

Relationship between Mental Health and Burden among Primary Caregivers of Outpatients with Schizophrenia

There is growing recognition that caring for a patient with schizophrenia often results in high levels of perceived burden and poorer overall mental health for caregivers. A quantitative cross‐sectional design and standardized instruments were used to collect data from 355 primary caregivers of adults in outpatient care with schizophrenia in China. Structural equation modeling was used to examine the association between caregiver burden and mental health among primary caregivers and whether this association is influenced by personality, coping style, and family functioning, based on a diathesis–stress perspective. Goodness‐of‐fit indices (χ²/df = 1.406, GFI = 0.919, CFI = 0.957, etc.) confirmed that the modified model fit the data well. In line with the diathesis–stress model, and with this study's hypotheses, we found that caregiver burden was significantly related to mental health outcomes directly. The final model showed that personality traits, coping style, and family function influenced the relationship between caregiver burden and mental health. The neuroticism personality traits have a direct effect on caregiver burden and family functioning in this sample. Coping style had a direct effect on the caregiver burden, and family functioning had a direct effect on the caregiver burden. Our final model about primary caregivers can be applied clinically to predict mental health outcomes from caregiver burden.     

Sadder but wiser: Emotional reactions and wisdom in a simulated suicide intervention

Scholars within the Berlin paradigm have analysed participants' responses to a hypothetical vignette about a friend's suicide ideation. However, no study has yet focused on participants' emotional reactions to this scenario, an important aspect of wisdom performance. We conducted a Thin‐Slice Wisdom study where participants were asked to give advice to a hypothetical friend contemplating suicide. We analysed their emotional profiles using facial expression analysis software (FACET2.1 and FACEREADER7.1). Participants' verbal responses were also transcribed and then scored by 10 raters using the Berlin criteria. Results revealed that the sadder the participants felt, the wiser their performance. Wiser participants may have been better at exploring this sad, but true, existential human dilemma.

职业刻板印象及其影响因素研究

通过外显报告和内隐联想测验,发现在外显和内隐层面,大学生存在明显的职业刻板印象,对某些职业评价很高,有些则很低。工作岗位所在不同地域对大学生职业刻板印象产生较大影响,隐藏着加工机制的深层问题。研究结果表明,大学生就业观存在某种偏差。     

线索对基本特征刺激加工作用机制研究

许多研究认为,基本特征的觉察过程是平行加工的过程,它的探测与注意分配到某个位置没有关系。本实验通过不同线索分配注意,探讨了基本特征的平行加工与选择性注意的作用的关系。结果发现：(1)基本特征的平行加工,可能受到注意分配影响的;(2)注意分配的作用可能通过抑制干扰项的加工,而不仅仅只是通过促进靶子的加工而实现的。作者在讨论中探讨了可能的原因。     

大学生消费心理和消费行为的研究

当代大学生是跨世纪的人才,是开创21世纪大业和进一步振兴中华的主力军,社会对大学生的整体素质提出了更高的要求。大学生所受的教育、校园的环境以及该年龄的特殊心理特征,使他们有自己特有的消费心理和消费行为,对他们的消费心理和消费行为的研究,有助于认识青年一代乃至整个社会的消费趋势。本文对当代大学生的消费水平、消费结构、消费方式、消费心理特点及其影响因素、对策等作了分析。     

分析性认知风格对偏差反应与冲突探查的影响

采用2Wingdings 2MC@2Wingdings 2MC@2混合设计和相关分析法,考察个体的分析性认知风格对其在完成有、无冲突的推理判断任务时的逻辑反应倾向和冲突探查过程的影响。结果表明分析性认知风格不会直接影响被试完成推理任务的逻辑反应倾向性,高、低分析性认知风格倾向组被试在逻辑反应正确率上不存在显著差异; 但对个体的冲突探查过程会有影响,高、低认知风格倾向组被试在反应自信率上存在显著差异,且冲突探查大小与分析性认知风格显著负相关,这一结果表明那些高分析性认知风格倾向的个体在完成冲突任务时,更可能探查到刻板反应与遵从逻辑规则做出的反应之间的冲突。
