Distraction and time estimation

It is argued that events which occur during an interval of time which is being judged may be classified in terms of their effects on the alertness of the subject, and in terms of the degree to which they distract him from the task of detecting and processing time-relevant cues. A distracting task, defined by the number of arithmetical operations a subject was required to perform, was presented while reproductions of an interval were being made. The data support the prediction that the higher the level of distraction, the less time a subject will judge to have elapsed during an objective period.     

Motivation and Academic Achievement: The Effects of Personality Traits and the duality of Experience

The present study examined the relationship of personality, experience while studying, and academic performance. One hundred and seventy talented high-school students (68 males, 102 females) completed the Personality Research Form (PRF) and recorded their experience via the Experience Sampling Method (ESM). The results showed that controlling for ability, work orientation, a PRF factor, was a better predictor of grade than experience. However, an experiential variable,intrinsic motivation while studying, was related to the difficulty level of courses students took over the 4 years of high school. The results supported the notion that there are two kinds of motivation in scholastic achievement, one directed toward long-term goals, the other directed toward ongoing experience.     

Developmental study of a haptic illusion in relation to Piaget's centration theory.

Age differences have previously been found in the magnitude of the visual Horizontal-vertical illusion with an L figure. The present study examined the haptic judgments of an L figure among subjects across the ages of 6, 7, 9, 11, 12, 13, and 20 years. Significant differences in amount of haptic illusion were found. The developmental function was curvilinear, decreasing from the 6-year-olds to 7-year-olds, and then increasing from 7-year-olds to a peak among 11-year-olds, followed by a decline to adulthood. Variation in the size of the illusion was also found to be related to the rate at which subjects of a particular age group typically move the limb in scanning the figure. The similarity of the haptic function to that obtained previously for the visual L figure was discussed in relation to Piaget's Centration theory.     

Cross‐cultural similarities and differences in the theoretical predictors of cyberbullying perpetration: Results from a seven‐country study

The Barlett Gentile cyberbullying model (BGCM) posits that correlated anonymity perceptions and the belief in the irrelevance of muscularity for online bullying (BIMOB) predict positive cyberbullying attitudes to predict subsequent cyberbullying perpetration. Much research has shown the BGCM to be the only published theory that differentiates traditional and cyberbullying while validly predicting cyberbullying. So far, however, the cross‐cultural ubiquity has gone understudied. Thus, 1,592 adult participants across seven countries (USA, Australia, Brazil, China, Germany, Japan, and Singapore) completed measures germane to the BGCM. Supporting the BGCM, the variables were significantly correlated for the entire sample, participants from independent cultures, and participants from interdependent cultures. However, the relationship between BIMOB and positive cyberbullying attitudes as well as the relationship between positive cyberbullying attitudes and cyberbullying perpetration were stronger for independent cultures. These results suggest that the BGCM postulates are mostly universal, but several relations appear to be culturally different. Theoretical implications are discussed.     

A preliminary study of an online pain management programme for patients with ankylosing spondylitis

This study was a preliminary attempt to develop and examine an online pain management programme incorporating mindfulness‐informed exercises (i.e. breathing and body scanning exercises) and CBT elements for ankylosing spondylitis patients. Thirty patients diagnosed with ankylosing spondylitis participated in a five‐week online pain management programme, which was delivered primarily through a website. The materials covered by the website included breathing and body scanning exercises, mindful walking exercise, positive thinking and management of dysfunctional thinking. Each participant received instructions and reminders from a counselling psychologist through electronic communications each week. They completed the Brief Pain Inventory, Ryff's Psychological Well‐being Scale, Pain Self‐Efficacy Questionnaire, Pain Catastrophizing Scale and Cognitive and Affective Mindfulness Scale‐Revised before and after the treatment programme. In addition, four face‐to‐face focus groups were conducted to yield supplementary qualitative findings. The overall results indicate that this online pain management programme can improve sleep quality and reduce pain interference and catastrophic responses to pain in ankylosing spondylitis patients, albeit being not very effective for mitigating the intensity of pain. Moreover, male and female patients can benefit equally from the online programme. Findings from the focus groups revealed some challenges faced by local patients when practising mindfulness‐informed exercises. Some solutions to those challenges were put forward in accordance with patients’ feedback.     

Sources of Care for Alcohol and Other Drug Problems: The Role of the African American Church

African Americans experience significant disparities in treatment access, retention, and quality of care for alcohol and drug use (AOD) problems. Religious congregations, often the first point of contact for help with AOD problems, can play an integral role in improving access to treatment. However, little is known about the role of African American churches in addressing AOD problems. We administered a survey to a faith-based collaborative of 169 African American churches in Los Angeles to examine how AOD problems are identified in congregations, the types of support provided, barriers to providing treatment referrals, and factors associated with the provision of treatment referrals. Seventy-one percent of churches reported caring often for individuals with AOD problems. AOD problems came to the attention of congregations most commonly via a concerned family member (55%) and less frequently through individuals with AOD problems directly approaching clergy (30%). In addition to providing spiritual support, a substantial proportion of churches reported linking individuals to AOD services through referrals (62%) and consultation with providers (48%). Barriers to providing treatment referrals included lack of affordable programs (50%), stigma (50%), lack of effective treatments (45%), and insufficient resources or staff (45%). The likelihood of providing treatment referrals was greater among mid-sized versus smaller-size congregations (OR 3.43; p < .05) and among congregations with clergy that had attended seminary (OR 3.93; p < .05). Knowing how to effectively coordinate informal sources of care provided by African American churches with the formal service sector could make a significant impact on AOD treatment disparities.     

Culturally Congruent Mentoring: Predicting Asian American Student Participation Using the Theory of Reasoned Action1

Predictors of Asian American first‐year college students’ intention to participate in a culturally congruent mentoring program was empirically documented using Ajzen and Fishbein's (1980) theory of reasoned action (TRA). Intention to participate was predicted by the belief that participation eases transition to college. Also, attitude toward participation was positively related to students’ beliefs that participation will strengthen ethnic identity and combat model‐minority myth. With 78% of students who intended to participate, results suggest that Asian American college students need programming that addresses issues as first‐year college students and those related to their cultural experience. The use of the TRA to better understand issues related to peer mentoring is illuminated. Wider implications for implementing culturally congruent mentoring programs in educational settings are discussed.     

Minimax d-optimal designs for item response theory models

Various different item response theory (IRT) models can be used in educational and psychological measurement to analyze test data. One of the major drawbacks of these models is that efficient parameter estimation can only be achieved with very large data sets. Therefore, it is often worthwhile to search for designs of the test data that in some way will optimize the parameter estimates. The results from the statistical theory on optimal design can be applied for efficient estimation of the parameters.A major problem in finding an optimal design for IRT models is that the designs are only optimal for a given set of parameters, that is, they are locally optimal. Locally optimal designs can be constructed with a sequential design procedure. In this paper minimax designs are proposed for IRT models to overcome the problem of local optimality. Minimax designs are compared to sequentially constructed designs for the two parameter logistic model and the results show that minimax design can be nearly as efficient as sequentially constructed designs.
