ICQ (I seek you) and adolescents: a quantitative study in Hong Kong.

The Hong Kong Government and the education sector encourage the whole population-from toddlers to senior citizens-to utilize information technology, and many do. Yet there are no studies exploring the patterns of adolescents using ICQ (I seek you) in Asian countries. This study was done in Hong Kong, which has the greatest number of ICQ users. A quantitative approach was adopted by administering self-constructed questionnaires to the students of one high school. One hundred and forty-seven adolescents volunteered to participate. The key findings of the study are (1) most of the adolescents have been using ICQ for 1-4 years; (2) most fit one of two patterns of use: either 2 or 3 days per week, or more than 5 days per week; (3) they spend less than 3 h per day on ICQ; (4) the main reasons for using ICQ are entertainment, relaxation, and socializing; and (5) parents are concerned about possible negative impacts on their children's academic performance because of using ICQ. Two main implications are drawn: proper use of ICQ can minimize parental distress and encourage adolescents to be less sedentary.     

VR-based conversation training program for patients with schizophrenia: a preliminary clinical trial.

Schizophrenia is a devastating mental illness and is characterized by hallucinations and delusions as well as social skills deficits. Generally, social skills training designed to help patients develop social skills includes role-playing, but this form of training has typical shortcomings, which are largely due to a trainer's difficulties to project emotion. Virtual reality (VR)-based techniques have the potential to solve these difficulties, because they provide a computer-generated but realistic three-dimensional world and humanlike avatars that can provide emotional stimuli. In this paper, we report on a method of implementing virtual environments (VEs) in order to train people with schizophrenia to develop conversational skills in specific situations, which could overcome the shortcomings of or complement conventional role-playing techniques. The paper reports the efficacy of the proposed approach in a preliminary clinical trial with 10 patients with schizophrenia.     

Recalling a Witnessed Event Increases Eyewitness Suggestibility: The Reversed Testing Effect

ABSTRACT— People's later memory of an event can be altered by exposure to misinformation about that event. The typical misinformation paradigm, however, does not include a recall test prior to the introduction of misinformation, contrary to what real-life eyewitnesses encounter when they report to a 911 operator or crime-scene officer. Because retrieval is a powerful memory enhancer (the testing effect), recalling a witnessed event prior to receiving misinformation about it should reduce eyewitness suggestibility. We show, however, that immediate cued recall actually exacerbates the later misinformation effect for both younger and older adults. The reversed testing effect we observed was based on two mechanisms: First, immediate cued recall enhanced learning of the misinformation; second, the initially recalled details became particularly susceptible to interference from later misinformation, a finding suggesting that even human episodic memory may undergo a reconsolidation process. These results show that real-life eyewitness memory may be even more susceptible to misinformation than is currently envisioned.     

Spatial working memory maintenance: Does attention play a role? A visual search study

Recent studies have proposed that a common mechanism may underlie spatial attention and spatial working memory. One proposal is that spatial working memory is maintained by attention-based rehearsal [Awh, E., Jonides, J., & Reuter-Lorenz, P. A. (1998). Rehearsal in spatial working memory. Journal of Experimental Psychology: Human Perception and Performance, 24(3), 780-790], and so a spatial attention shift during the retention interval of a spatial location should impair its memory performance. In the present study, participants engaged in single-item, parallel or serial search tasks while remembering a spatial location. Although memory tended to bias all searches, the need for an attentional shift during the retention interval impaired memory performance only in single-item search, but not in other searches. These findings suggest that previous evidence for the attention-based rehearsal account does not generalize to visual search. Results are discussed with regard to the relationship between spatial attention and spatial working memory.     

Self‐esteem as a source of evaluative conditioning

This study was designed to examine whether self‐esteem can be used as a source of evaluative conditioning, and whether implicit or explicit self‐esteem was more predictive of the evaluative conditioning effect. Moreover, the role of contingency awareness in the acquisition of the evaluative conditioning effect was also examined. Words related to the self and a general other were served as unconditioned stimuli (USs) in the evaluative conditioning process in order to see whether the evaluation could be transferred to neutral, abstract paintings after 10 times of pairing. An evaluative conditioning effect was demonstrated in that the evaluation of the paintings became more positive after repeatedly paired with words about the self but not words about general others. Implicit self‐esteem predicted the magnitude of the evaluative conditioning effect, while the association between explicit self‐esteem and the evaluative conditioning effect was nonsignificant, both with and without the effect of contingency awareness being controlled for.

Surviving the Kosovo Conflict: A Study of Social Identity, Appraisal of Extreme Events, and Mental Well-Being

Our study examined the role of social identity processes in determining how individuals evaluate, deal with, and are affected by severe events of war. We reasoned that for those who experience such events collectively and who identify strongly with their group, primary appraisal will be filtered through the prism of social identity. In a sample of Kosovo Albanians who had survived the armed conflict in 1999, we found that those who were able to evaluate the war as affirming their group identity presented lower levels of depressive mood and anxiety and higher levels of self-efficacy. Furthermore, this process of war appraisal affected the process of secondary appraisal. Specifically, positive war appraisal increased availability of support from close others and reduced the importance of positive individual coping strategies in dealing with extreme events. Conversely, negative war appraisal reduced availability of support from close others and reduced the importance of negative coping strategies in dealing with extreme events.     

Neural correlates of Traditional Chinese Medicine induced advantageous risk-taking decision making

This fMRI study examined the neural correlates of the observed improvement in advantageous risk-taking behavior, as measured by the number of adjusted pumps in the Balloon Analogue Risk Task (BART), following a 60-day course of a Traditional Chinese Medicine (TCM) recipe, specifically designed to regulate impulsiveness in order to modulate risk-taking behavior. The 14 participants recruited for this study were randomly assigned to the experimental and control groups and the TCM recipe (Panax, 520 mg; Astragalus membranaceous Bunge, 520 mg; Masnetitum, 840 mg; Ostrea gigas Thumb, 470 mg; Thinleaf Milkwort Root Radix Polygalae, 450 mg; and Os Draconis, 470 mg) was administered, as a diet supplement, to the seven participants in the experimental group. The neural activity of the two groups was monitored by a 3T MRI scanner, before and after the 60-day treatment. Associated with the improved advantageous risk-taking behavior seen in the experimental group, significantly stronger blood oxygenation level dependent (BOLD) responses were observed in the bilateral dorsolateral prefrontal cortex (DLPFC), left putamen, left thalamus, right insula, and right anterior cingulate cortex (ACC), regions which have previously been reported as being involved in risk-taking decision making. The effect of the TCM in improving advantageous risk-taking decision making appears to have been related to the enhanced efficiency of the cognitive affective system, the PFC–ACC–insula–striatum network, which functions to inhibit impulsiveness, to sensitize reward-related information, and to allow the opportunity, during risk estimation, to evaluate potential gains and losses. The findings of this study suggest that interventions acting on factors modulating risk-taking decision making could have a beneficial effect in terms of optimizing risk-taking behavior.     

Evaluating the two-component inspection model in a simplified luggage search task

Visual inspection of X-ray images of luggage is a time-pressured task that typically shows large initial training effects, but there exists a paucity of models capable of evaluating performance and speed concurrently. In the present study, visual inspection ability during learning was modeled using Drury’s two-component inspection model (TCM; Drury, 1975) in a laboratory experiment involving 12 younger (mean age = 20.8 years) and 12 older (mean age = 60.0 years) naive participants undertaking a simplified luggage search task. Model fits and assumptions were found to be reliable and accurately reflected improvement with training for decision time, although neither search nor decision components of the model individually showed a significant effect of age. The decision component of the model showed larger improvement with training than did the search component, and stopping-time policy accurately reflected the improvements found between ages and within training levels. The TCM is a useful supplement to detection theory when speed of performance is a factor.     

Helping to improve the group stereotype: on the strategic dimension of prosocial behavior

Three studies consider a basis for intergroup helping. Specifically, they show that group members may help others to disconfirm a stereotype of their own group as mean. Study 1 shows that Scots believe they are seen as mean by the English, resent this stereotype, are motivated to refute it, and believe out-group helping is a particularly effective way of doing so. Study 2 shows that increasing the salience of the English stereotype of the Scottish as mean leads Scots to accentuate the extent to which Scots are depicted as generous. Study 3 shows that increasing the salience of the stereotype of the Scots as mean results in an increase in the help volunteered to out-group members. These results highlight how strategic concerns may result in out-group helping. In turn, they underscore the point that helping others may be a means to advance a group's interest.
