The modulation of semantic transparency on the recognition memory for two-character Chinese words

This study demonstrated that semantic transparency as a linguistic property modulates the recognition memory for two-character Chinese words, with opaque words (i.e., words whose meanings cannot be derived from constituent characters—e.g., “光[/guang/, light]棍[/gun/, stick]”, bachelor) remembered better than transparent words (i.e., words whose meanings can be derived from constituent characters—e.g., “茶[/cha/, tea]杯[/bei/, cup]”, teacup). In Experiment 1, the participants made lexical decisions on transparent words, opaque words, and nonwords in the study and then engaged in an old/new recognition test. Experiment 2 employed a concreteness judgment as the encoding task to ensure equivalent semantic processing for opaque and transparent words. In Experiment 3, the neighborhood size of the two-character words was manipulated together with their semantic transparency. In all three experiments, opaque words were found to be better remembered than transparent words. We concluded that the conceptual incongruence between the meanings of a whole word and its constituent characters made opaque words more distinctive and, hence, better remembered than transparent words.     

Different types of exercise induce differential effects on neuronal adaptations and memory performance

Different exercise paradigms show differential effects on various forms of memory. We hypothesize that the differential effects of exercises on memory performance are caused by different neuroplasticity changes in relevant brain regions in response to different exercise trainings. We examined the effects of treadmill running (TR) and wheel running (WR) on the Pavlovian fear conditioning task that assesses learning and memory performance associated with the amygdala (cued conditioning) and both the amygdala and hippocampus (contextual conditioning). The skeletal muscle citrate synthase activity, an indicator of aerobic capacity, was elevated in rats received 4 w of TR, but not WR. While both TR and WR elevated the contextual conditional response, only TR facilitated the cued conditional response. Using a single-neuron labeling technique, we found that while both TR and MR enlarged the dendritic field and increased the spine density in hippocampal CA3 neurons, only TR showed these effects in basolateral amygdalar neurons. Moreover, both types of exercise upregulated synaptic proteins (i.e., TrkB and SNAP-25) in the hippocampus; however only TR showed similar effects in the amygdala. Injection of K252a, a TrkB kinase inhibitor, in the dorsal hippocampus or basolateral amygdala abolished the exercise-facilitated contextual or cued fear learning and memory performance, respectively, regardless of the types of exercise. In summary, our results supported that different types of exercise affect the performance of learning and memory via BDNF-TrkB signaling and neuroplasticity in specific brain regions. The brain region-specific neuronal adaptations are possibly induced by various levels of intensity/stress elicited by different types of exercise.     

Transmission of religious beliefs in college students

The aim of the current study was to assess factors contributing to the generational transmission of religious beliefs in a sample of college students. Participants were 92 students from a small Catholic university in the southeastern United States. Students were surveyed in school regarding family relationships, communication, and religious values. Overall, results indicated that children’s and parents’ religious beliefs were significantly correlated. Furthermore, children were fairly accurate reporters of their parents’ religious beliefs. Some gender differences were found in the strength of the correlations between parents’ and children’s beliefs. Additionally, explicit communication, implicit communication, and perception of parents’ beliefs predicted children’s beliefs. The current study holds clinical and developmental significance by examining the manner in which religiosity is expressed within the familial milieu of emerging adults.     

The Strength to Cope: Spirituality and Faith in Chronic Disease

The lifelong management of a chronic condition requires considerable mental fortitude and commitment in social adjustment and adherence to medical advice. In examining strategies of adaptation, we draw on ethnographic research, including interviews with 69 people with type 2 diabetes and/or cardiovascular disease. We explore how they incorporate spirituality into their self-management routines, with positive impact on their health and wellbeing, and highlight the role of spiritual practices in supporting people with chronic conditions mentally, physically and socially, so encouraging personal responsibility for one’s health and wellbeing.     

Simulating Univariate and Multivariate Nonnormal Distributions through the Method of Percentiles

This article derives a standard normal-based power method polynomial transformation for Monte Carlo simulation studies, approximating distributions, and fitting distributions to data based on the method of percentiles. The proposed method is used primarily when (1) conventional (or L) moment-based estimators such as skew (or L-skew) and kurtosis (or L -kurtosis) are unknown or (2) data are unavailable but percentiles are known (e.g., standardized test score reports). The proposed transformation also has the advantage that solutions to polynomial coefficients are available in simple closed form and thus obviates numerical equation solving. A procedure is also described for simulating power method distributions with specified medians, inter-decile ranges, left-right tail-weight ratios (skew function), tail-weight factors (kurtosis function), and Spearman correlations. The Monte Carlo results presented in this study indicate that the estimators based on the method of percentiles are substantially superior to their corresponding conventional product-moment estimators in terms of relative bias. It is also shown that the percentile power method can be modified for generating nonnormal distributions with specified Pearson correlations. An illustration shows the applicability of the percentile power method technique to publicly available statistics from the Idaho state educational assessment.     

From Super Mario to Skyrim: A framework for the evolution of video game consumption

In contrast with traditional forms of entertainment media (e.g., movies, novels, and television), video games are unique in their ability to provide immersion, agency, and transformation (IAT) during the consumptive experience. As the video game medium has evolved over generations of consoles, the experience of IAT has become increasingly complex from the perspective of consumers. To better understand this phenomenon, this research presents a framework for understanding the consumption of video games by examining the intersection of player, narrative, and gameplay. Our findings suggest that advancements in video game technology and design have gradually increased the degree of integration among these domains. Although the subjective experience of IAT has generally improved as a function of greater integration, various conflicts arise from the tensions that exist between player, narrative, and gameplay. Consequently, this research explores the specific nature of such conflicts to provide a richer understanding of video game consumption and the impact of its evolution on consumers.

A Cross-Sectional Examination of International Competency Standards

The evaluation of competency in the field of psychology has gained international attention in recent years. Focusing on international competencies can promote high standards of care and identify common values of the profession. However, there is little research regarding international perceptions of competency. Examining ethics codes from different countries can highlight international standards of competent practice, as ethics codes outline professional expectations of the field. The current study compared the ethics standards found in 47 codes of ethics representing 51 countries. Seventeen competency standards emerged after ethics codes were analyzed. Implications for the international practice of psychology are discussed.
