Effects of number of items on the baboon's discrimination of same from different visual displays

Three experiments explored the baboon's discrimination of visual displays that comprised 2 to 24 black-and-white computer icons; the displayed icons were either the same as (same) or different from one another (different). The baboons' discrimination of same from different displays was a positive function of the number of icons. When the number of icons was decreased to 2 or 4, the baboons responded indiscriminately to the same and different displays, exhibiting strong position preferences. These results are both similar to and different from those of pigeons that were trained and tested under comparable conditions. Accepted after revision: 23 May 2001 Electronic Publication     

Multiple visualisation in data analysis: a ViSta application for principal component analysis

Multiple visualisation (MV) is a statistic graphical method barely applied in data analysis practice, even though it provides interesting features for this purpose. This paper: (1) describes the application of the MV graphical method; (2) presents a number of rules related to the design of an MV; (3) introduces a general outline for developing MVs and shows how MV may be implemented in the ViSta statistical system; (4) illustrates this strategy by means of an example of MV oriented to principal component analysis; and, finally, (5) discusses some limitations of using and developing MVs.     

Multiple processes associated with self-esteem as a function of attribute types

Previous studies (e.g., [Pelham, B. W. (1995). Self-investment and self-esteem: evidence for a Jamesian model of self-worth. Journal of Personality and Social Psychology, 69, 1141–1150]) showed that self-esteem is positively associated with (1) perceived alignment of self-views with internal standards (Differential Importance: DI) and (2) perceived alignment of self-views with external-social standards (Normative Importance: NI). The present research shows that these processes of self-esteem differ as a function of the types of self-attributes that constitute self-esteem. Specifically, for attributes of high cultural relevance (i.e., indigenous attributes), self-esteem is positively related to DI but not NI; for attributes of lower cultural relevance, self-esteem is positively related to NI but not DI. Self-esteem is positively related to DI for both agentic and communal indigenous attributes, whereas it is also positively related to NI for communal indigenous attributes.     

The role of active exploration of 3D face stimuli on recognition memory of facial information

Research on face recognition has mainly relied on methods in which observers are relatively passive viewers of face stimuli. This study investigated whether active exploration of three-dimensional (3D) face stimuli could facilitate recognition memory. A standard recognition task and a sequential matching task were employed in a yoked design. Observers in the active condition explored 3D views of faces via a mouse or joystick during the training and test sessions of the task, whereas observers in the passive condition simply viewed the replay of the same sequence of face stimuli generated by the active observers. It was found that the active condition produced better recognition accuracy than the passive condition. The study provides the first evidence that active exploration of 3D face stimuli can lead to better face recognition memory and matching performance.

The validity of DSM-IV passive-aggressive (negativistic) personality disorder

Passive-Aggressive (Negativistic) Personality Disorder (NEGPD), listed in Appendix B of the DSM-IV, is not an officially recognized personality disorder. Its future as a discrete disorder is uncertain (Widiger, 2003). Yet, NEGPD occupies a role in some theoretical formulations of personality pathology (Millon & Davis, 1996), and many clinicians believe that passive-aggressive traits are not adequately represented by other PDs (Westen, 1997). In this study, 1158 psychiatric outpatients were assessed for Axis I and Axis II disorders. Thirty-five (3.02%) met criteria for NEGPD. Participants with NEGPD did not differ significantly from those without NEGPD on demographic variables. The internal consistency of the DSM-IV's seven NEGPD items was 0.50. Corrected item- total correlations for the 7 criteria averaged 0.27. Participants with NEGPD had higher rates of lifetime anxiety disorders, and almost 90% had an additional PD. An exploratory factor analysis suggested a two- factor solution that accounted for 43.4% of the variance. The first factor reflected the belief that life is unfair, while the second factor seemed to reflect modes of anger expression. A confirmatory factor analysis showed that the two-factor model fit the data better than a unidimensional model. We discuss implications of these results for the future of the NEGPD diagnosis.     

Greater attention problems during childhood predict poorer executive functioning in late adolescence

Attention problems (behavior problems including inattention, disorganization, impulsivity, and hyperactivity) are widely thought to reflect deficits in executive functions (EFs). However, it is unclear whether attention problems differentially relate to distinct EFs and how developmental stability and change predict levels of EFs in late adolescence. We investigated, in an unselected sample, how teacher-rated attention problems from ages 7 to 14 years related to three correlated but separable EFs, measured as latent variables at age 17. Attention problems at all ages significantly predicted later levels of response inhibition and working memory updating, and to some extent set shifting; the relation to inhibiting was stronger than the relations to the other EFs or IQ. Growth models indicated that attention problems were quite stable in this age range, and it was the initial levels of problems, rather than their changes across time, that predicted later EFs. These results support the hypothesis that attention problems primarily reflect difficulties with response inhibition.     

青少年Stroop效应和反转Stroop效应的脑事件相关电位研究

Testing the relationship between three-component organizational/occupational commitment and organizational/occupational turnover intention using a non-recursive model

This study explored the relationship between three-component organizational/occupational commitment and organizational/occupational turnover intention, and the reciprocal relationship between organizational and occupational turnover intention with a non-recursive model in collectivist cultural settings. We selected 177 nursing staffs out of 30 hospitals in Taiwan as our sample, and structural equation modelling analysis was conducted to test our hypotheses. The results showed that normative organizational commitment negatively correlates with organizational turnover intention most strongly, and affective occupational commitment negatively correlates with occupational turnover intention most strongly. Moreover, organizational turnover intention plays a mediating role in the relationship between normative organizational commitment and occupational turnover intention, while occupational turnover intention mediates the relationship between affective occupational commitment and organizational turnover intention. In particular, the reciprocal relationship exists between organizational and occupational turnover intention. Practical implications and suggestions for future research were also discussed.     

Evidence Based Treatments for Bipolar Disorder in Children and Adolescents

Limited research has been devoted to developing and testing psychosocial treatments for bipolar disorder (BPD) in children and adolescents, a chronic and impairing mental illness that has received increased attention in recent years. Existing treatments are intended as adjuncts to medication, and share a family-based psychoeducation approach. Components of four treatments are discussed: family-focused treatment (FFT), the RAINBOW Program, multi-family psychoeducation groups (MFPG), and individual family psychoeducation (IFP). Evidence supporting each approach is detailed. Selected components of MFPG are described. A flowchart provides suggestions for sequencing interventions to maximize effectiveness. To illustrate the use of evidence-based treatment for children with BPD, a case example is provided.
