Differential effects of assisted cycling therapy on short-term and working memory of adolescents with Down syndrome

Persons with Down syndrome (DS) suffer from prefrontal cortex dysfunction and deficits in executive functions. The current study examined the effects assisted cycling therapy (ACT) on short-term (STM) and working memory (WM) in adolescents with DS. During ACT, the cadence of participants on a stationary bicycle was augmented with an electrical motor to 180% of the voluntary cadence. Participants completed eight weeks of ACT (n?=?17), eight weeks of voluntary cycling (VC) at their own preferred cadence (n?=?16), or eight weeks of no cycling (np?≥?.149) and working memory improved only in the ACT group (Hedge’s g?=?1.66; p?=?.003). The results indicate that assisted high-cadence cycling (i.e. ACT) produces superior neural benefits in the dorsolateral prefrontal cortex compared to VC.     

Comparison and Analysis of Selected English Interpretations of the Tao Te Ching

In the last 150 years, the ambiguous and enigmatic 81 chapters of the Tao Te Ching have been translated, interpreted and adapted into the English language more than 100 times. The Tao and its subtle philosophy is currently being actively assimilated into mainstream western culture as evidenced by the popularity and volume of Taoist works. The purpose of this study was to analyse this phenomenon. First, a database of English translations of the Tao Te Ching was established. This database documents the vast number of Tao Te Ching translations in print from 1868 to the present. Second, specific chapters of selected English translations of the Tao Te Ching were compared using holistic and content analysis. The holistic methods focused on the overall semantic connotation of the selected chapters. The specific (linguistic) analysis methods entailed the use of a computerised content analysis program (hyperRESEARCH for Macintosh). Through these inquiries, a specific understanding of the cross-cultural relationship between East and West was investigated.     

Do older individuals have difficulty processing motion or excluding noise? Implications for safe driving

This study aimed to determine if difficulties extracting signal from noise explained poorer coherent motion thresholds in older individuals, particularly women. In four experimental conditions the contrast of the signal and noise dots used in a random dot kinematogram was manipulated. Coherence thresholds were highest when the signal dots were of a lower contrast than the noise dots and lowest when the signal dots were of a higher contrast than the noise dots. In all conditions the older group had higher coherence thresholds than the younger group, and women had higher thresholds than men. Significant correlations were found between coherence thresholds and self-reported driving difficulties in conditions in which the signal dots had to be extracted from noise only. The results indicate that older individuals have difficulties extracting signal from noise in cluttered visual environments. The implications for safe driving are discussed.     

When Beliefs Lead to (Im)Moral Action: How Believing in Torture's Effectiveness Shapes the Endorsement of Its Use

Does believing in torture's effectiveness shape the endorsements of its use? Using a multimethod approach across six studies, we provide converging evidence that efficacy beliefs can help increase understanding of individual differences and situational influences on torture support. Studies 1a and 1b found that torture opinions contained more efficacy‐based language than other types of harm and that people relied more on torture efficacy than torture's inherent morality when conveying their views. Study 2 assessed predictors of torture favorability including effectiveness and other key covariates, revealing that efficacy beliefs strongly predicted torture favorability—an association that retained its predictive validity above and beyond individual differences known to influence torture support. Mediation analyses further showed that efficacy beliefs explained key associations with torture support. Studies 3 and 4 used moral dilemmas requiring decisions about torture versus other harm. Results showed that individuals who believed harm would be effective were more likely to endorse its use; this was especially evident for torture judgments. Study 5 replicated the torture‐efficacy effect while also revealing efficacy effects for other interrogation techniques, thus suggesting the effect is driven more by the instrumental objective of torture than harm or moral violations. Theoretical and practical implications are discussed.     

A Qualitative Investigation of Practicing Psychologists' Attitudes Toward Research-Informed Practice: Implications for Dissemination Strategies

This article presents the results of a qualitative analysis of interviews with 25 psychologists in independent practice, investigating everyday treatment decisions and attitudes about treatment outcome research and empirically supported treatments (ESTs). Clinicians noted positive aspects about treatment outcome research, such as being interested in what works. However, they had misgivings about the application of controlled research findings to their practices, were skeptical about using manualized protocols, and expressed concern that nonpsychologists would use EST lists to dictate practice. Clinicians reported practicing in an eclectic framework, and many reported including cognitive-behavioral elements in their practice. To improve their practice, they reported valuing clinical experience, peer networks, practitioner-oriented books, and continuing education when it was not too basic. Time and financial barriers concerned nearly all participants. Clinicians suggested they might be interested in ESTs if they could integrate them into their current frameworks, and if resources for learning ESTs were improved.     

Linking personality to interpersonal citizenship behaviour: The moderating effect of empathy

To account for generally low direct relationships between Big‐Five personality traits and interpersonal citizenship behaviour (ICB), researchers have suggested that Big‐Five traits are associated with such helping‐related behaviour in interactive rather than direct fashion. This study investigated empathy as a potential moderator of Big‐Five trait – ICB relations. Hypotheses were tested with data obtained from employees of a youth treatment facility and their supervisors. Results provided evidence that empathy interacts with three Big‐Five personality traits, suggesting traits functioning at conceptually different hierarchical levels may jointly explain specific behaviours. Empathy could play an important role in understanding connections between these Big‐Five traits and ICB.     

Exogenous attention influences visual short-term memory in infants

Two experiments examined the hypothesis that developing visual attentional mechanisms influence infants' Visual Short-Term Memory (VSTM) in the context of multiple items. Five- and 10-month-old infants (N = 76) received a change detection task in which arrays of three differently colored squares appeared and disappeared. On each trial one square changed color and one square was cued; sometimes the cued item was the changing item, and sometimes the changing item was not the cued item. Ten-month-old infants exhibited enhanced memory for the cued item when the cue was a spatial pre-cue (Experiment 1) and 5-month-old infants exhibited enhanced memory for the cued item when the cue was relative motion (Experiment 2). These results demonstrate for the first time that infants younger than 6 months can encode information in VSTM about individual items in multiple-object arrays, and that attention-directing cues influence both perceptual and VSTM encoding of stimuli in infants as in adults.     

Large errors, but no depth compression, in walked indications of exocentric extent

Observers can sight a target 20 m away or more and then walk to it accurately without vision. In contrast to this good performance, this article shows that walked indications of the exocentric separation of two locations exceed the required values by over 70% when vision is obscured. Significantly, these large errors are coupled with a robust lack of depth foreshortening, even under conditions in which visual matches and verbal estimates of extent exhibit strong evidence of depth compression. This article presents evidence that the overshooting errors are due largely to recalibration of locomotor control produced by prolonged exposure to nonvisual walking. The robust lack of depth foreshortening, meanwhile, could reflect a corresponding isotropy in the spatial representation controlling the walking response. More research is needed to confirm this interpretation, however.     

The Relation of Social Capital to Child Psychosocial Adjustment Difficulties: The Role of Positive Parenting and Neighborhood Dangerousness

Substantial research attention has focused on the psychosocial adjustment problems of children and adolescents residing in disadvantaged neighborhoods. However, less attention has been directed to neighborhood factors within disadvantaged neighborhoods that may facilitate child psychosocial adjustment. An expanded model, assessing how social capital, neighborhood dangerousness, and positive parenting relate to child psychosocial adjustment difficulties, was estimated using structural equation modeling (Lisrel 8.3). Participants included 130 African American mothers and their children (mean age = 12.9 years) residing in inner city New Orleans, LA. The model examined 3 avenues through which social capital (e.g., support, neighborhood cohesion) may relate to fewer child psychosocial adjustment difficulties: a direct relation; through its relation to positive parenting; and through its relation to neighborhood dangerousness. Results indicate that social capital related to child psychosocial adjustment difficulties through positive parenting and neighborhood dangerousness, but not directly. Overall, the proposed model fit the observed data reasonably well. The results suggest that social capital in disadvantaged neighborhoods is important in indirectly facilitating child psychosocial adjustment and should be incorporated into assessment and intervention practices.     

Ethnography and Subjectivity in Comparative Religious Ethics

The ethnographic turn in religious studies has responded to important developments, such as the rejection of value neutrality and the need to better address the lived experience of individuals and communities. In this essay, I affirm the value of ethnography as a method in comparative religious ethics, but distinguish between two ways of framing ethnography in relation to ethics. The first way insists on the hard limits of translating values across cultures, and tends to marginalize or dismiss normative inquiry. The second way allows for the interpretation of practices of ethical justification in diverse cultural contexts. I argue that this second category of ethnography is more congenial to the work of comparative religious ethicists, since an integral part of ethical inquiry involves reflecting on, and making arguments about, social norms and practices.
