Thinking Styles and the Eriksonian Stages

The primary objective of this study was to investigate the predictive power of thinking styles for psychosocial development. Four hundred and twenty-six (212 men and 214 women) students from a large comprehensive university in Shanghai, the People??s Republic of China, responded to the Thinking Styles Inventory-Revised II (TSI-R2, Sternberg, Wagner, and Zhang 2007) and the Measures of Psychosocial Development (MPD, Hawley 1988). The TSI-R2 is based on Thinking styles, Cambridge University, Press, New York, (1997) theory of mental self-government, while the MPD is based on Identity: Youth and crisis, W.W. Norton, New York, (1968) theory of psychosocial development. Results suggested that after the variables gender and academic discipline were controlled for, creativity-generating styles positively contributed to psychosocial development and that norm-favoring styles negatively contributed to psychosocial development. Implications of these findings are discussed for university students, faculty members, and for university student development educators.     

Nurses' behaviors and visual scanning patterns may reduce patient identification errors

Patient identification (ID) errors occurring during the medication administration process can be fatal. The aim of this study is to determine whether differences in nurses' behaviors and visual scanning patterns during the medication administration process influence their capacities to identify patient ID errors. Nurse participants (n = 20) administered medications to 3 patients in a simulated clinical setting, with 1 patient having an embedded ID error. Error-identifying nurses tended to complete more process steps in a similar amount of time than non-error-identifying nurses and tended to scan information across artifacts (e.g., ID band, patient chart, medication label) rather than fixating on several pieces of information on a single artifact before fixating on another artifact. Non-error-indentifying nurses tended to increase their durations of off-topic conversations-a type of process interruption-over the course of the trials; the difference between groups was significant in the trial with the embedded ID error. Error-identifying nurses tended to have their most fixations in a row on the patient's chart, whereas non-error-identifying nurses did not tend to have a single artifact on which they consistently fixated. Finally, error-identifying nurses tended to have predictable eye fixation sequences across artifacts, whereas non-error-identifying nurses tended to have seemingly random eye fixation sequences. This finding has implications for nurse training and the design of tools and technologies that support nurses as they complete the medication administration process.     

社会支持网络对城市贫困人口身心状况的影响

摘 要 通过对天津贫困人口的随机样本的分析,探讨了社会支持的数量、质量和社会支持网的网络结构对贫困人口的身心状况的影响。研究发现,社会支持的数量对城市贫困人口的身心状况没有影响。社会支持的质量则对贫困人口的身心状况有正向的影响。社会支持网的异质性越高,趋同性越低,生活满意度越高。这些指标对身体健康则没有影响。但网络中高于中心成员收入水平的越多,身心状况越差。     

抑郁症早醒对事件相关电位的关系研究

本研究旨在探讨抑郁症睡眠障碍早醒与事件相关电位P300的关系。 通过对22例抑郁症早醒病人、20例抑郁症非早醒病人及20例健康自愿者进行事件相关电位P300和汉密尔顿抑郁量表检测,结果发现,早醒组与对照组比较P2、N2、P3潜伏期与反应时间明显延长(P＜0.05),P2、N2、P3波幅明显降低;非早醒组与对照组比较N2、P3潜伏期与反应时间明显延长(P＜0.05),N2、P3波幅明显降低;早醒组与非早醒组比较P2、N2、P3潜伏期与反应时间明显延长(P＜0.05),N2、P3波幅明显降低。早醒组HAMD评分明显高于非早醒组(P＜0.05)。研究表明抑郁症早醒与非早醒病人均存在认知功能的损害,损害程度早醒病人比非早醒病人更为严重。     

Impaired Pavlovian conditioned inhibition in offenders with personality disorders

Certain types of violent offending are often accompanied by evidence of personality disorders (PDs), a range of heterogeneous conditions characterized by disinhibited behaviours that are generally described as impulsive. The tasks previously used to show impulsivity deficits experimentally (in borderline personality disorder, BPD) have required participants to inhibit previously rewarded responses. To date, no research has examined the inhibition of responding based on Pavlovian stimulus-stimulus contingencies, formally "conditioned inhibition" (CI), in PDs. The present study used a computer-based task to measure excitatory and inhibitory learning within the same CI procedure in offenders recruited from the "personality disorder" and the "dangerous and severe personality disorder" units of a high-security psychiatric hospital. These offenders showed a striking and statistically significant change in the expression of inhibitory learning in a highly controlled procedure: The contextual information provided by conditioned inhibitors had virtually no effect on their prepotent associations. Moreover, this difference was not obviously attributable to nonspecific cognitive or motivational factors. Impaired CI would reduce the ability to learn to control associative triggers and so could provide an explanation of some types of offending behaviour.

Gender differences in creative thinking revisited: Findings from analysis of variability

This study investigated gender differences in creativity among 985 schoolchildren (499 boys, 486 girls) by analyzing both means and variability. A relatively new creativity test, the Test for Creative Thinking-Drawing Production (TCT-DP), was employed to gain a more refined understanding of gender differences in creativity using a gestalt approach. Whereas the results of analyses of means generally supported the Gender Similarities Hypothesis, the variability analyses tended to support the Greater Male Variability Hypothesis and the Gender Difference Hypothesis. Analyses of the TCT-DP subscales revealed that both genders have their relative strengths and weaknesses in creative thinking. Whereas girls outperformed boys in thoroughness of thinking, boys outperformed girls in boundary-breaking thinking. Variability analyses further showed that more boys clustered in the two extremes of the composite score. Significantly greater variability was found for males on five criteria of the TCT-DP. The educational implications of such a complex pattern of gender differences are discussed. With a view to searching for an explanation for gender differences, several lines of further research are proposed.     

Civic engagement in relation to outcome expectations among African American young adults

The present study examined civic engagement—volunteering and political activism—among 129 African American young adults from an urban community. The proposed model considered factors that motivate young adults to participate in civic activities as well as barriers that might inhibit involvement. Drawing upon social cognitive theory, this study highlighted the role of two related, but independent, types of civic attitudes: community and individual outcome expectations (OEs) as Bandura defines them. Results indicated that perceptions of neighborhood conditions are linked to community OEs, whereas previous involvement in political actions is linked to individual OEs. Analyses also revealed that community and individual OEs are differentially associated with young adults' intentions to engage in future civic activities. Study findings contribute to an area of research that has received limited investigation and are discussed in terms of developing strategies to support civic engagement among African American young adults in urban settings.     

Age and emotion affect how we look at a face: visual scan patterns differ for own-age versus other-age emotional faces

We investigated how age of faces and emotion expressed in faces affect young (n=30) and older (n=20) adults' visual inspection while viewing faces and judging their expressions. Overall, expression identification was better for young than older faces, suggesting that interpreting expressions in young faces is easier than in older faces, even for older participants. Moreover, there were age-group differences in misattributions of expressions, in that young participants were more likely to label disgusted faces as angry, whereas older adults were more likely to label angry faces as disgusted. In addition to effects of emotion expressed in faces, age of faces affected visual inspection of faces: Both young and older participants spent more time looking at own-age than other-age faces, with longer looking at own-age faces predicting better own-age expression identification. Thus, cues used in expression identification may shift as a function of emotion and age of faces, in interaction with age of participants.
