Likelihood of attending to the color word modulates Stroop interference

Three experiments investigated whether the Stroop color-naming effect is modulated by the likelihood of a color word capturing visual attention. In Experiment 1, a bar or a neutral word was presented at fixation as a color carrier, along with a color word randomly appearing in either an achromatic color (white in the main experiment, gray in a follow-up) or purple. Reduction of the Stroop effect (known as Stroop dilution) occurred when the color word was achromatic but not (or to a lesser extent) when it was in purple. In Experiment 2, the color of the color word remained constant throughout trial blocks, and Stroop dilution was equally evident when the word was always in purple and when it was always in white. In Experiment 3, a color bar was presented as the color carrier with both a color word and a neutral word. In this case, the Stroop effect was larger when the color word appeared in purple, and smaller when the neutral word appeared in purple, than when neither word did. These results imply that the extent to which processing of a color word occurs is determined by the likelihood of the word capturing attention.     

A Retrospective Analysis of the Trend of Retracted Publications in the Field of Biomedical and Life Sciences

Among the many forms of research misconduct, publishing fraudulent data is considered to be serious where the confidence and validity of the research is detrimentally undermined. In this study, the trend of 303 retracted publications from 44 authors (with more than three retracted publications each) was analysed. The results showed that only 6.60% of the retracted publications were single-authored and the discovery of fraudulent publications had reduced from 52.24 months (those published before the year 2000) to 33.23 months (those published on the year 2000 and onwards). It appears that with the widely accessible public databases like PubMed, fraudulent publications can be detected more easily. The different approaches adopted by authors who had previous publications retracted are also discussed herein.     

Reduced automatic motivational orientation towards food in restricting anorexia nervosa

A striking and characteristic feature of the restricting subtype of anorexia nervosa (AN) is that they are extremely successful in regulating their food intake in a destructive manner. A possible explanation for the persistent character of their restricted food intake could be a loss of the motivational saliency of food in restricting AN patients. The present study aimed to investigate motivational orientation for food in the restricting subtype of anorexia nervosa with an indirect performance-based measure and a self-report measure of craving. An indirect approach avoidance task was administered to measure automatic approach tendencies for high-fat and low-fat food in restricting adolescent AN-like patients (n=89) and a group of healthy adolescents (n=76). As predicted, restricting AN-like patients showed less automatic motivational orientation toward food than healthy controls. In a similar vein, AN-like patients reported less craving for food than the group of healthy controls. The loss of an automatic motivational orientation toward food together with the deliberate strategy to avoid food might help explain the ability of restricting AN-like patients to regulate their food intake.     

Angry facial expressions hamper subsequent target identification

There is considerable evidence indicating that people are primed to monitor social signals of disapproval. Thus far, studies on selective attention have concentrated predominantly on the spatial domain, whereas the temporal consequences of identifying socially threatening information have received only scant attention. Therefore, this study focused on temporal attention costs and examined how the presentation of emotional expressions affects subsequent identification of task-relevant information. High (n = 30) and low (n = 31) socially anxious women were exposed to a dual-target rapid serial visual presentation (RSVP) paradigm. Emotional faces (neutral, happy, angry) were presented as the first target (T1) and neutral letter stimuli (p, q, d, b) as the second target (T2). Irrespective of social anxiety, the attentional blink was relatively large when angry faces were presented as T1. This apparent prioritized processing of angry faces is consistent with evolutionary models, stressing the importance of being especially attentive to potential signals of social threat.     

Migrant mental health: a model for indicators of mental health and health care consumption.

OBJECTIVE: This study explores the relationship between mental health and health care consumption among migrants in the Netherlands. DESIGN: Samples of the Turkish (n = 648), Moroccan (n = 102), and Surinamese (n = 311) populations in Amsterdam were examined. The study tested a hypothesized model of risk factors for psychiatric morbidity, indicators of well-being, and indicators of health care consumption. The model was specified on the basis of information from earlier research on the sample and literature on the topic. The model was tested and refined using structural equation modeling. MAIN OUTCOME MEASURES: Psychiatric morbidity and well-being measures were assessed with the CIDI 1.1 and MOS-sf-36 subscales, respectively. Health care consumption was assessed by the question "Have you ever consulted one or more of these professionals or health care facilities with respect to mental health problems or problems related to alcohol or drugs usage?" RESULTS: The primary result of this study was the confirmation that health care consumption among migrants is predicted by need and predisposition factors, such as health condition and sociodemographic characteristics. In addition, mental health care consumption of migrants is predicted by acculturation characteristics. This result suggests an effect of cultural and migrant-specific factors in help-seeking behavior and barriers to mental health care facilities. CONCLUSIONS: Findings confirm the existence of migrant-specific mechanisms in health care consumption. Mental health care professionals should be aware of these. However, ignoring common ground for interventions unnecessarily creates distance between migrant groups and between migrant and indigenous Dutch groups.     

Transferring the technology,policy, and management concept from the Netherlands to China

The literature on policy transfer between countries and organization has seen rapid growth. Whether framed in terms of policy transfer, institutional transplantation, imitation and emulation or copying policy models and ideas, a sizeable number of determinants for success have been identified to understand why such conceptual or institutional transfers grow out to become successes or failures in their countries or organizations of adoption. What is much less common is to describe such a process through the lens of participants inside this transfer. This paper is an attempt to do just that. It will tell the story of the higher-educational concept of Technology, Policy and Management from Delft University of Technology in the Netherlands to Harbin Institute of Technology in China, studied by means of participatory observation. The keys and clues for successful transplantation from the literature will subsequently be compared with the experiences from this case, and additional lessons, some of which are specific to Western-Chinese mutual learning, are formulated.

Detection of emotional expressions in rapidly changing facial displays in high- and low-socially anxious women

Facial information and attention to facial displays are distributed over spatial as well as temporal domains. Thus far, research on selective attention to (dis)approving faces in the context of social anxiety has concentrated primarily on the spatial domain. Using a rapid serial visual presentation (RSVP) paradigm, the present study examined the temporal characteristics of visual attention for happy and angry faces in high- (n=16) and low-socially anxious individuals (n=17), to test whether also in the temporal domain socially anxious individuals are characterized by threat-confirming attentional biases. Results indicated that presenting angry faces as the first target (T1) did not aggravate the detection of the emotional expression of the second target (T2). Yet, participants generally showed superior detection of the emotional expression of T2, if T2 was an angry face. Casting doubt on the role of such attenuated attentional blink for angry faces in social anxiety, no evidence emerged to indicate that this effect was relatively strong in high-socially anxious individuals. Finally, the presentation of an angry face as T2 resulted in a relatively hampered identification of a happy-T1. Again, this "backward blink" was not especially pronounced in high-socially anxious individuals. The present anger superiority effects are consistent with evolutionary models stressing the importance of being especially vigilant for signals of dominance. Since the effects were not especially pronounced in high-anxious individuals, the present study adds to previous findings indicating that socially anxious individuals are not characterized by a bias in the (explicit) detection of emotional expressions [Philippot, P., & Douilliez, C. (2005). Social phobics do not misinterpret facial expression of emotion. Behaviour Research and Therapy, 43, 639-652].     

Predicting job seeking for temporary employment using the theory of planned behaviour: The moderating role of individualism and collectivism

Using the theory of planned behaviour (TPB), the role of behavioural, normative, and control beliefs and individualism/collectivism was examined in the context of job seeking for temporary employment. Data were collected in a two‐wave longitudinal design, using a culturally diverse sample of 138 temporary workers in The Netherlands. Results supported the TPB‐relationships, with the exception of the role of perceived behavioural control (PBC). Of the behavioural beliefs, sense of security, work–life balance, and status were most strongly related to intentions to seek temporary employment. Further, hypothesized moderating effects of collectivism were confirmed such that people low on collectivism were more strongly motivated by their personal attitudes about job seeking and less by perceptions of social pressure than people high on collectivism. Thus, the TPB was demonstrated to work somewhat differently depending on people's cultural value orientations.     

Expectancy bias and the persistence of posttraumatic stress

Anxious individuals tend to overestimate the probability that encounters with anxiogenic stimuli (CS) will be followed by aversive consequences (UCS). This study examined whether such (biased) UCS expectancies predict the persistence of PTSD symptoms. A total of 265 soldiers were recruited before a four-month deployment to Iraq in 2004. About 2-5 months after deployment, 171 (65%) soldiers completed self-report scales about adverse events in Iraq and PTSD symptoms, and a UCS expectancy task. In this task, participants were exposed to a series of deployment-related and deployment-unrelated (control) picture stimuli. For each trial, the participants indicated the subjective probability that a particular slide would be followed by an imminent loud noise. Around 15 months after deployment, 130 (76%) soldiers completed surveys about PTSD symptoms again. Only a small group of participants had high levels of PTSD symptoms. Regression analyses showed that the level of PTSD symptoms at 15 months was predicted by earlier PTSD symptoms, but also and independently by an enhanced UCS expectancy to deployment-related stimuli. The findings support the notion that UCS expectancy bias contributes to the persistence of PTSD symptoms.     

Colours sometimes count: awareness and bidirectionality in grapheme-colour synaesthesia

Three experiments were conducted with 10 grapheme-colour synaesthetes and 10 matched controls to investigate (a) whether awareness of the inducer grapheme is necessary for synaesthetic colour induction and (b) whether grapheme-colour synaesthesia may be bidirectional in the sense that not only do graphemes induce colours, but that colours influence the processing of graphemes. Using attentional blink and Stroop paradigms with digit targets, we found that some synaesthetes did report “seeing” synaesthetic colours even when they were not able to report the inducing digit. Moreover, congruency effects (effects of matching the colour of digit presentation with the synaesthetic colour associated with that digit) suggested that grapheme-colour synaesthesia can be bidirectional, at least for some synaesthetes.
