Rapid eye-fixation training without eyetracking

Maintenance of stable central eye fixation is crucial for a variety of behavioral, electrophysiological, and neuroimaging experiments. Naive observers in these experiments are not typically accustomed to fixating, either requiring the use of cumbersome and costly eyetracking or producing confounds in results. We devised a flicker display that produced an easily detectable visual phenomenon whenever the eyes moved. A few minutes of training using this display dramatically improved the accuracy of eye fixation while observers performed a demanding spatial attention cuing task. The same amount of training using control displays did not produce significant fixation improvements, and some observers consistently made eye movements to the peripheral attention cue, contaminating the cuing effect. Our results indicate that (1) eye fixation can be rapidly improved in naive observers by providing real-time feedback about eye movements, and (2) our simple flicker technique provides an easy and effective method for providing this feedback.

Getting it right by getting it wrong: When learners change languages

When natural language input contains grammatical forms that are used probabilistically and inconsistently, learners will sometimes reproduce the inconsistencies; but sometimes they will instead regularize the use of these forms, introducing consistency in the language that was not present in the input. In this paper we ask what produces such regularization. We conducted three artificial language experiments, varying the use of determiners in the types of inconsistency with which they are used, and also comparing adult and child learners. In Experiment 1 we presented adult learners with scattered inconsistency - the use of multiple determiners varying in frequency in the same context - and found that adults will reproduce these inconsistencies at low levels of scatter, but at very high levels of scatter will regularize the determiner system, producing the most frequent determiner form almost all the time. In Experiment 2 we showed that this is not merely the result of frequency: when determiners are used with low frequencies but in consistent contexts, adults will learn all of the determiners veridically. In Experiment 3 we compared adult and child learners, finding that children will almost always regularize inconsistent forms, whereas adult learners will only regularize the most complex inconsistencies. Taken together, these results suggest that regularization processes in natural language learning, such as those seen in the acquisition of language from non-native speakers or in the formation of young languages, may depend crucially on the nature of language learning by young children.     

Modern Sequential Analysis and Its Applications to Computerized Adaptive Testing

After a brief review of recent advances in sequential analysis involving sequential generalized likelihood ratio tests, we discuss their use in psychometric testing and extend the asymptotic optimality theory of these sequential tests to the case of sequentially generated experiments, of particular interest in computerized adaptive testing. We then show how these methods can be used to design adaptive mastery tests, which are asymptotically optimal and are also shown to provide substantial improvements over currently used sequential and fixed length tests.     

Validation of the Preschool Anxiety Scale-Traditional Chinese (PAS-TC) in Hong Kong

Anxiety disorders are the most common type of psychiatric conditions in children. Early identification and intervention during preschool years is critical for minimizing their detrimental long-term effects. The Preschool Anxiety Scale (PAS) is a developmentally-sensitive and symptom-specific instrument that has been commonly used and widely validated in the west. The current study tested the psychometric properties of its Traditional Chinese version (PAS-TC) in Hong Kong. The study sample consisted of a total of 1317 Hong Kong parents, recruited from 12 local preschools, with preschool children aged from three to six years old. Results showed that a correlated five-factor model demonstrated a good fit for the data. PAS-TC also demonstrated acceptable reliability and satisfactory validity. Furthermore, gender but not age effects were found in Hong Kong. Additionally, similar to previous studies, items from physical injury fears were the most reported in the top-ten frequently endorsed items. Finally, the anxiety level of our Hong Kong sample was found to be between the Mainland China and western countries. Clinical implications of the above findings concerning PAS-TC are discussed.

     

Parenting and toddler self-regulation in low-income families: What does sleep have to do with it?

Toddlerhood is a sensitive period in the development of self-regulation, a set of adaptive skills that are fundamental to mental health and partly shaped by parenting. Healthy sleep is known to be critical for self-regulation; yet, the degree to which child sleep alters interactive child–parent processes remains understudied. This study examines associations between observed parenting and toddler self-regulation, with toddler sleep as a moderator of this association. Toddlers in low-income families (N = 171) and their mothers were videotaped during free play and a self-regulation challenge task; videos were coded for mothers’ behavior and affect (free play) and toddlers’ self-regulation (challenge task). Mothers reported their child's nighttime sleep duration via questionnaire. Results revealed significant Sleep × Maternal Negative Affect and Sleep × Maternal Negative Control interactions. Children who did not experience negative parenting had good self-regulation regardless of their nighttime sleep duration. For children who did experience negative parenting, self-regulation was intact among those who obtained more nighttime sleep, but significantly poorer among children who were getting less nighttime sleep. Thus, among children who were reported to obtain less nighttime sleep, there were more robust associations between negative parenting and poorer self-regulation than among toddlers who were reported to obtain more sleep.     

Stressful life events, motives for Internet use, and social support among digital kids.

This study presents the interrelationships between stressful life events, motives for Internet use, social support, and the use of the Internet among a sample of adolescents and children aged 8 to 18 (N = 717). The results show that stressful life events are significantly associated with the consumption of the Internet for mood management (such as entertainment and information seeking) and social compensation (such as recognition gaining and relationship maintenance) motives. Secondly, the more children and adolescents exhibit high levels of social support, either online or offline, the less they find stressful life events upsetting. Thirdly, as individuals exhibit greater ability to personally access different types of social support to meet their needs, their motivations for Internet use are characteristically more allied to mood-management and social-compensation. This study reasserts that the mental and physical impact of stressful life events are in fact buffered by one's degree of social support and Internet use, particular examples of which are entertainment and relationship maintenance, and positive coping strategies, which temporarily reduce stress and anxiety.     

Asian social psychology: Achievements, threats, and opportunities

A scan of citation impact suggests that Asian social psychologists have made significant contributions in three areas: indigenous research, culture and social behaviour, and in several topics in social psychology. An analysis of the most cited articles published in Asian Journal of Social Psychology ( AJSP ) in 1998–2002 in March 2005 reveals that most papers are concerned with culture, with a focus on either popular topics in the West or indigenous concepts. Asian social psychology seems to be closely associated with cultural issues, but it still lacks unique theoretical contributions, and the number of internationally visible scholars is limited and is mostly confined to East Asia. However, Asian cultures provide a fertile ground for identifying new constructs. Many Asian universities are now under pressure to internationalize, which will motivate more academics to participate in Asian conferences and publish in AJSP . To develop Asian social psychology, effort should be focused on nurturing the next generation of Asian social psychologists, who not only need an international perspective, but also ambition and creativity.     

Licensure of Internationally Educated Nurses Seeking Professional Careers in the Province of Alberta in Canada

While the regulation of nursing practice through licensure ensures that nurses meet minimum standards for safe competent and ethical care, it also inhibits integration of immigrant internationally educated nurses (IENs) into the Canadian professional labour market. With projections of significant nurse workforce shortages by 2010, there is impetus to enhance the numbers of licensed professional nurses through multiple strategies. The licensure processes and accompanying tensions in the Canadian context are described. As professional nurse licensure in Canada is a provincial responsibility, the situation in the Province of Alberta is used as an example. Suggestions for policy development and research include needs for better data and for gender-based analysis to address barriers to IEN licensure. The ability to practice in one’s chosen profession can be a major factor in integration of immigrants into Canadian society and thus a powerful factor in attraction and retention of highly skilled immigrants.     

Learning conditional frequencies in a probability learning task

The study was prompted by a theoretical discussion of probability learning by Estes (1976). In three separate experiments, subjects were presented with frequency information in the form of wins and losses among 3 teams, and later predicted future wins and losses. Frequencies were devised so that conditional win frequencies for a pair of teams were either inconsistent or consistent with marginal win frequencies for each team. In experiment 1, when subjects predicted future events on the basis of known past frequencies, predictions were generally based on conditional frequencies. In experiment 2 six blocks of observations were presented, with predictions following each block. What little learning did occur was in the direction of the conditional frequencies. Subjects in experiment 3 were able to learn conditional frequencies when given explicit instructions to do so. Results were discussed in terms of a two-stage hypothesis generation model that might operate within the framework of an associative theory of probability learning.     

“Decoding MH”—A de-stigmatization campaign in the Hong Kong Police Force

Police officers are under high level of stress given the intense and emergent work nature. If left untreated, their mental wellbeing would be at risk and work performance compromised. However, mental health stigma is common among police officers and is perpetuated by factors like police cultures emphasizing toughness and self-reliance. In view of this, since 2016, the Hong Kong Police Force had launched a holistic campaign for Force members which was the first among law enforcement organizations in Hong Kong, aiming to reduce stigma, by enhancing mental health knowledge and decreasing negative attitudes and behaviors towards mental health issues. The programme incorporated standardised trainings of the Mental Health First Aid course with examples modified to the local police context, and psychoeducation via the use of digital medium and sharing by public figures. Positive feedback was received. It was foreseen that the campaign effects would increase Force members' awareness of their mental health, encourage help-seeking and facilitate officers' decision making when encountering crises in the community.
