Development and content validity of a screening instrument for gaming addiction in adolescents: The Gaming Addiction Identification Test (GAIT)

This study describes the development of a screening tool for gaming addiction in adolescents – the Gaming Addiction Identification Test (GAIT). Its development was based on the research literature on gaming and addiction. An expert panel comprising professional raters (n = 7), experiential adolescent raters (n = 10), and parent raters (n = 10) estimated the content validity of each item (I‐CVI) as well as of the whole scale (S‐CVI/Ave), and participated in a cognitive interview about the GAIT scale. The mean scores for both I‐CVI and S‐CVI/Ave ranged between 0.97 and 0.99 compared with the lowest recommended I‐CVI value of 0.78 and the S‐CVI/Ave value of 0.90. There were no sex differences and no differences between expert groups regarding ratings in content validity. No differences in the overall evaluation of the scale emerged in the cognitive interviews. Our conclusions were that GAIT showed good content validity in capturing gaming addiction. The GAIT needs further investigation into its psychometric properties of construct validity (convergent and divergent validity) and criterion‐related validity, as well as its reliability in both clinical settings and in community settings with adolescents.     

Psychometric evaluation of the adolescent and parent versions of the Gaming Addiction Identification Test (GAIT)

The objective of the study is to evaluate the psychometric properties of the Gaming Addiction Identification Test (GAIT) and its parent version (GAIT‐P), in a representative community sample of adolescents and parents in Västmanland, Sweden. Self‐rated and parent‐rated gaming addictive symptoms identified by GAIT and GAIT‐P were analyzed for frequency of endorsement, internal consistency, concordance, factor structure, prevalence of Internet gaming disorder (IGD), concurrence with the Gaming Addiction Scale for Adolescents, 7‐item version (GAS) and the parent version of GAS (GAS‐P), and for sex differences. The 12‐month prevalence of IGD was found to be 1.3% with GAIT and 2.4% with GAIT‐P. Results also indicate promising psychometric results within this population, with high internal consistency, and high concurrent validity with GAS and GAS‐P. Concordance between adolescents and parents ratings was high, although moderate in girls. Although exploratory factor analysis indicated poor model fit, it also indicated unidimensionality and high factor loadings in all analyses. GAIT and GAIT‐P are suitable for continued use in measuring gaming addiction in adolescents, and, with the additional two items, they now cover all nine IGD criteria.     

Additive and interactive effects in memory for subject-performed tasks

Abstract

Three experiments were carried out to explore reasons for the superior recall and recognition of subject-performed tasks (SPTs) relative to memory for the equivalent verbal commands. In Experiment 1, list structure was varied; list structure affected recall, but the variable did not interact with the SPT/command manipulation. The same absence of an interaction was found in Experiment 2 with respect to different retrieval conditions and also with respect to the age of adult subjects. Experiment 3 confirmed that the age difference was as large for SPTs as it was for verbal commands. In addition, an interaction between SPT/command and levels of processing was found in Experiment 3. Differences between the additive and interactive patterns of results are discussed in terms of SITS contributing both additional (possibly motoric) information and also conceptual information that overlaps with information added by other variables.     

The Prospective and Retrospective Memory Questionnaire (PRMQ): factorial structure, relations to global subjective memory ratings, and Swedish norms

The factorial structure of the Prospective and Retrospective Memory Questionnaire (PRMQ; Smith et al., 2000) was examined in a Swedish population based sample (N= 540, age range; 35-90 years). Concurrent validity was assessed by relating PRMQ to global ratings of memory. Confirmatory factor analyses of the PRMQ items indicated a superior fit of a three-factor model, with prospective and retrospective memory as orthogonal factors and episodic memory as a common factor. Furthermore, the PRMQ scales correlated with the global ratings of memory, suggesting that each rating contributed with unique variance in predicting PRMQ scores. Given differences in levels of complaints as compared with prior research (Crawford et al., 2003) norms for the Swedish version are provided. In conclusion, the present findings extend earlier work by providing additional support for the construct and concurrent validity of the PRMQ scales.     

Exploring the conjunction fallacy within a category learning framework

The literature presents two major theories on the cause of the conjunction fallacy. The first attributes the conjunction fallacy to the representativeness heuristic. The second suggests that the conjunction fallacy is caused by people combining p(A) and p(B) into p(A&B) in an inappropriate manner. These two theories were contrasted in two category‐learning experiments. As predicted by the latter theory, data showed that participants that could assess p(A&B) directly made fewer conjunction fallacies than participants who had to compute p(A) and p(B) separately and then combine them into p(A&B). Least conjunction fallacies were observed in the cases where the representativeness heuristic was applicable. Overall, data showed that an inability to appropriately combine probabilities is one of the key cognitive mechanisms behind the conjunction fallacy. Copyright © 2008 John Wiley & Sons, Ltd.     

Cross-sectional versus longitudinal age gradients of tower of Hanoi performance: the role of practice effects and cohort differences in education

We examined 5-year longitudinal changes in Tower of Hanoi (TOH) performance in a population-based sample of adults (35-85 years initially; n = 1480). An age-matched sample (n = 433) was included to estimate practice effects. The longitudinal age gradients differed substantially from the cross-sectional age gradients. This was the case even when practice effects, that were substantial in magnitude across the young/middle-aged groups, were controlled for. Instead of a continuous age-related deficit in performance from 35 and onwards, longitudinal data showed slowing of performance and increases of illegal moves past age 65. Cohort-related differences in educational attainment did not account for this discrepancy. Further analyses revealed a positive relation between practice-related gains and explicit memory of having performed the task at the first test occasion and a positive association between latent changes in TOH and Block Design, in line with cross-sectional findings. In conclusion, the results demonstrate a pattern of age-related changes indicating a late-onset decline of TOH performance and underscore the need to control for retest effects in longitudinal aging research.     

Sign- and goal-tracking in Atlantic cod (<Emphasis Type="Italic">Gadus morhua</Emphasis>)

When animals associate a stimulus with food, they may either direct their response towards the stimulus (sign-tracking) or towards the food (goal-tracking). The direction of the conditioned response of cod was investigated to elucidate how cod read cue signals. Groups of cod were conditioned to associate a blinking light (conditioned stimulus, CS) with a food reward (unconditioned stimulus, US), with the CS and the US located at opposite sides of the tank. Two groups were trained in a delay conditioning procedure (CS = 60 s, interstimulus interval = 30 s) and two groups were trained in a trace conditioning procedure (CS = 12 s, trace interval = 20 s). The response pattern was similar for the delay- and trace-conditioned groups. The initial main response at the onset of the CS was approaching the blinking lights, i.e. sign-tracking. In the early trials, the fish did not gather in the feeding area before the arrival of food. In the later trials, the fish first approached the blinking lights, but then moved across the tank and gathered below the feeder before the food arrived, i.e. sign-tracking followed by goal-tracking within each trial. These two responses are interpreted as reflecting two learning systems, i.e. one rapid, reflexive response directed at the signal (sign-tracking) and one slower, more flexible response based on expectations about time and place for arrival of the food (goal-tracking). The ecological significance of these two learning systems in cod is discussed.     

Internet-mediated distance-learning education in China as an alternative to traditional paradigms of market entry

Globalization and technology are two power forces that have shaped trade, investment, industrial development and people in the twentieth and twenty-first centuries. Faced with these forces, universities, on the one hand, internationalized their curriculums, students and faculty and, on the other hand, enhanced their technological base, such as the use of computers, internet infrastructure, and technology-based instructional capabilities. These two efforts have largely been mutually exclusive with little intersection between the two. This article analyzes the cross-over between a university’s potential to internationalize with respect to China, the most populous country with the second largest Purchasing Power Parity Gross Domestic Product (PPP GDP) in the world, and to use its technological capabilities to extend its educational outreach. Indirect presence in the Chinese market through Internet-mediated distance-learning education is thus proposed because of its attractiveness from effectiveness and efficiency perspectives, and because China has experienced an increase in its technological and infrastructural environments that enable this mode of entry. Distance learning education via e-commerce in China can be economically viable, consistently scalable, politically feasible, and expediently realizable.

Effects on Episodic Memory of Stimulus Richness, Intention to Learn, and Extra-Study Repetition: Similar Profiles Across the Adult Life Span

The ability to benefit from various kinds of cognitive support in episodic memory was studied in a population-based sample of healthy adults aged 35–80 years (N = 1,000). The participants studied pictures of faces and names of 10-year-old children with instructions to remember the faces and the surnames. After study, an implicit name stem-completion test was administered, followed by face- and name-recognition tests. There was a negative age effect across all task variables. Across age, recognition was higher for faces than for names. An age-invariant positive effect of intention to learn was observed. Also, name completion and recognition performance showed a positive relationship across the adult life span. Overall, the results are in agreement with the views that (a) age-related episodic memory deficits are highly generalizable and (b) effects of cognitive support on memory are typically of equal size across the adult life span.     

Cultivating Mindfulness Through The Practice Of Iaidō

Iaidō is a Japanese swordsmanship art that teaches the practitioner, iaidokan, a series of sword techniques known as kata. The number, and severity of [sword] techniques increases as the practitioner achieves higher grades (kyu and dan). To understand and conduct the [spiritual] core of iaidō, the iaidoka must learn how to be attentive and bodily and mindfully present when carrying out these [sword] techniques. In this respect, mindfulness training could be of great help by enhancing the ability of the iaidokan skills in this regard. Additionally, mindfulness training may be used to teach the practitioner of iaidō how to develop a being-mode. This article discusses, from both an outside-in perspective, as academic researcher and an inside-out perspective as a mindfulness and iaidō practitioner, the meaning of iaidō in terms of attention, [mindfulness] meditation and a being-mode. This discussion may prepare the way for a new and inspiring understanding of Asian spiritual practices in a Western guise.
