Comprehension of Online Informed Consents: Can It Be Improved?

This study examined possible ways to ensure that participants provide fully informed consent for online surveys. Participants were randomly assigned to read either a traditional informed consent or one of three modified versions: enhanced (e.g., images, bullet points), consent for each key element, or a combination of these two. Those who read the combination version scored higher on a comprehension quiz, guessed at fewer questions, and were more likely to read all of the informed consent than those who received the traditional version. These findings suggest that comprehension can be improved by adopting alternatives to the traditional informed consent.     

Behavioural variability and motor performance: Effect of practice specialization in front crawl swimming

The aim was to examine behavioural variability within and between individuals, especially in a swimming task, to explore how swimmers with various specialty (competitive short distance swimming vs. triathlon) adapt to repetitive events of sub-maximal intensity, controlled in speed but of various distances. Five swimmers and five triathletes randomly performed three variants (with steps of 200, 300 and 400 m distances) of a front crawl incremental step test until exhaustion. Multi-camera system was used to collect and analyse eight kinematical and swimming efficiency parameters. Analysis of variance showed significant differences between swimmers and triathletes, with significant individual effect. Cluster analysis put these parameters together to investigate whether each individual used the same pattern(s) and one or several patterns to achieve the task goal. Results exhibited ten patterns for the whole population, with only two behavioural patterns shared between swimmers and triathletes. Swimmers tended to use higher hand velocity and index of coordination than triathletes. Mono-stability occurred in swimmers whatever the task constraint showing high stability, while triathletes revealed bi-stability because they switched to another pattern at mid-distance of the task. Finally, our analysis helped to explain and understand effect of specialty and more broadly individual adaptation to task constraint.     

Capturing worry in daily life: are trait questionnaires sufficient?

Worry is crucial in the development and maintenance of anxiety disorders and has been associated with several other adverse health outcomes. Yet, little is known about the frequency and perseveration of worry in daily life, and its predictability by widely used trait questionnaires. In this study 432 students completed the Penn State Worry Questionnaire (PSWQ), the Worry Domains Questionnaire (WDQ) and the State-Trait Anxiety Inventory-Trait version (STAI-T) and kept a log of worry frequency and duration during six consecutive days and nights. The results showed that worry is a very common phenomenon that is predicted by the two trait worry questionnaires, independent of trait anxiety. The often clinically utilized PSWQ predicted worry duration better than the WDQ, and exclusively predicted night-time worry and several other indices of perseverative and potentially pathogenic worry. Although this study provides some support for the predictive validity of the PSWQ and the WDQ, these questionnaires did not account for the larger part of variance in daily worry. Future studies of worry and its associated perseverative processes should consider using momentary assessments.     

Missed Opportunities: Speculation on What Japanese Psychology Could Have Been

Takasuna (Integr. Physiol. Behav. Sci. 41, 2007) mentioned the ease with which evolutionary theory was accepted by Japanese psychologists, and certainly this is admirable. He also mentioned the stubborn force which had to be used to gain an understanding of the (thoroughly Western) subjective–objective distinction. Alas, during the formative years of Japanese psychology, there was much philosophical work afoot attempting to destroy that distinction. It is speculated that only a small change of which books were translated, or with which Americans early Japanese psychologists trained under, would have made Japan into a haven for these still underdog theories.     

The role of neighborhood ecological assets and activity involvement in youth developmental outcomes: Differential impacts of asset poor and asset rich neighborhoods

Developmental system theories recognize that variables from multiple levels of organization within the bioecology of human development contribute to adolescent development, including individual factors, family factors and the neighborhood which includes extracurricular activities. Extracurricular activities provide a context for youth development, and participation has been linked with positive developmental outcomes. This study uses data from a subsample of early adolescents in the 4-H Study of Positive Youth Development to determine whether neighborhood assets moderate the effect of adolescent activity involvement on positive and negative developmental outcomes. The relationship between activity involvement and neighborhood assets was different for girls as compared to boys when assessing outcomes of positive youth development, risk behavior, and depression. Consistent with a developmental systems perspective, the findings affirm the need for researchers and practitioners to consider multiple contextual influences when seeking to understand or promote, respectively, positive youth development.     

Information–movement coupling in developing cricketers under changing ecological practice constraints

Changing informational constraints of practice, such as when using ball projection machines, has been shown to significantly affect movement coordination of skilled cricketers. To date, there has been no similar research on movement responses of developing batters, an important issue since ball projection machines are used heavily in cricket development programmes. Timing and coordination of young cricketers (n = 12, age = 15.6 ± 0.7 years) were analyzed during the forward defensive and forward drive strokes when facing a bowling machine and bowler (both with a delivery velocity of 28.14 ± 0.56 m s⁻¹). Significant group performance differences were observed between the practice task constraints, with earlier initiation of the backswing, front foot movement, downswing, and front foot placement when facing the bowler compared to the bowling machine. Peak height of the backswing was higher when facing the bowler, along with a significantly larger step length. Altering the informational constraints of practice caused major changes to the information–movement couplings of developing cricketers. Data from this study were interpreted to emanate from differences in available specifying variables under the distinct practice task constraints. Considered with previous findings, results confirmed the need to ensure representative batting task constraints in practice, cautioning against an over-reliance on ball projection machines in cricket development programmes.     

The problem of delayed causation in a video game: Constant, varied, and filled delays

A first-person shooter video game was adapted for the study of causal decision making within dynamic environments. The video game included groups of three potential targets. Participants chose which of the three targets in each group was producing distal explosions. The actual source of the explosion effect varied in the delay between the firing of its weapon and the effect (from 0 to 2 s), whether these programed average delays were constant or varied from shot to shot, and whether the delays were unfilled or filled with an auditory event. In Experiment 1, participants’ choice accuracy was highest with shorter delays, but there was no effect of filling the delay and some beneficial effect of varying the delay. These results were re-examined in Experiment 2 but with participants experiencing the same average delay for seven subsequent decisions before the next average delay was introduced. In this experiment, men showed a strong and consistent benefit of filling a delay whereas women did not. Participants’ behavior is considered within the context of a model that assumes that choice behavior is driven by experienced contiguity for the target and foils.     

Costs and benefits of cultural value mismatch in the globalising era: A commentary on the special issue “cross-cultural value mismatch: A by-product of migration and population diversity around the world” (IJP,December, 2018)

In this commentary, the author first seeks to counterbalance the current focus on the cost of cultural value mismatch by calling attention to ample evidence in the literature that value mismatch can produce cultural adaptation and resilience in the long run, besides promoting cultural innovations and individual creativity. Second, we propose three factors that differentiate the benefits from the costs of cultural value mismatch. Personal orientation towards integrating heritage and host culture, accurate perception of cultural value differences, and supportive multicultural environments are associated with benefits. In contrast, dichotomous orientation towards one or the other culture, exaggeration of value differences between heritage and host culture, and assimilationist social environments are associated with costs. Third, our analysis of the decoupling between cultural values and ecological niches in the special issue led to observation of bidirectionality in cultural value mismatch: Whereas most articles in the Special Issue focus on the cross-cultural value mismatch that occurs when people move from a more rural, low-resource, less technological ecology into a more urban, high-resource, more technological ecology, we were able to document the effects of value mismatch when movement occurs in the opposite direction.
