Evaluation of key points in the sit-to-stand movement using two force platforms

Three key points of the sit-to-stand (STS) movement were confirmed as aspects of the ground reaction force (GRF): the onset, maximum GRF, and seat-off. 46 healthy subjects (M age = 22.2 yr., SD = 4.4) participated. During the STS movement, two vertical force platforms were used to measure the resultant GRF, defined as the whole-body force, and its two components, the buttock and leg GRFs. The onsets of the component GRFs identified the sequence of the important time points in the STS movement more precisely than the onset of the resultant GRF. Data showed that the maximum whole-body GRF, the maximum GRF of both legs, and seat-off appeared in sequence and not simultaneously.     

Multilevel factor analysis and structural equation modeling of daily diary coping data: Modeling trait and state variation

The current study used multilevel modeling of daily diary data to model within-person (state) and between-person (trait) components of coping variables. This application included the introduction of multilevel factor analysis (MFA) and a comparison of the predictive ability of these trait/state factors. Daily diary data was collected on a large (n = 366) multiethnic sample over the course of five days. Intraclass correlation coefficient for the derived factors suggested approximately equal amounts of variability in coping usage at the state and trait levels. MFAs showed that Problem-Focused Coping and Social Support emerged as stable factors at both the within-person and between-person levels. Other factors (Minimization, Emotional Rumination, Avoidance, Distraction) were specific to the within-person or between-person levels, but not both. Multilevel structural equation modeling (MSEM) showed that the prediction of daily positive and negative affect differed as a function of outcome and level of coping factor. The Discussion section focuses primarily on a conceptual and methodological understanding of modeling state and trait coping using daily diary data with MFA and MSEM to examine covariation among coping variables and predicting outcomes of interest.     

The cultural dynamics of rewarding honesty and punishing deception

Recent research suggests that individuals reward honesty more than they punish deception. Five experiments showed that different patterns of rewards and punishments emerge for North American and East Asian cultures. Experiment 1 demonstrated that Americans rewarded more than they punished, whereas East Asians rewarded and punished in equivalent amounts. Experiments 2 and 3 revealed that these divergent patterns by culture could be explained by greater social mobility experienced by Americans. Experiments 4 and 5 examined how certain consequences of social mobility, approach-avoidance behavioral motivations and trust and felt obligation, can lead to disparate reward and punishment decisions within the two cultures. Moreover, Experiment 4 revealed that Americans exhibited stronger evaluative reactions toward deception but stronger behavioral intentions toward honesty; East Asians did not exhibit this evaluative-behavioral asymmetry. The cross-cultural implications for understanding rewards and punishments in an increasingly globalized world are discussed.     

Experts see it all: configural effects in action observation

Biological motion perception is influenced by observers’ familiarity with the observed action. Here, we used classical dance as a means to investigate how visual and motor experience modulates perceptual mechanism for configural processing of actions. Although some ballet moves are performed by only one gender, male and female dancers train together and acquire visual knowledge of all ballet moves. Twenty-four expert ballet dancers (12 female) and matched non-expert participants viewed pairs of upright and inverted point light female and common dance movements. Visual discrimination between different exemplars of the same movement presented upright was significantly better in experts than controls, whilst no differences were found when the same stimuli were presented upside down. These results suggest expertise influences configural action processing. Within the expert group, effects were stronger for female participants than for males, whilst no differences were found between movement types. This observer gender effect could suggest an additional role for motor familiarity in action perception, over and above the visual experience. Our results are consistent with a specific motor contribution to configural processing of action.     

Exploring the roles of narcissism,uses of,and gratifications from microblogs on affinity‐seeking and social capital

The purpose of this study is to examine how the uses and gratifications of microblogs (i.e. Sina Weibo) can influence interpersonal relationships, especially in affinity‐seeking and perceived social capital. Data were gathered through an online questionnaire with a sample of 431 Weibo users surveyed throughout mainland China. Results show that (i) narcissism, content‐, and social‐gratification were positively related to intensity of Weibo use, (ii) intensity of Weibo use and process‐gratification were positively related to strategic performance, whereas only content‐gratification positively predicted affinity competence. (iii) content‐ and social‐gratification positively predicted bridging social capital, whereas convenience‐gratification and affinity‐seeking predicted bonding social capital, and (iv) intensity of Weibo use was positively related to both types of social capital only when Weibo gratifications were not included in the regression equations. Implications and suggestions for future research are discussed.     

Aspirant Sage or Dysfunctional Seer? Cognitive Dissonance and Pastoral Vulnerability in the Profile of Daniel

Employing a psychological lens and using the “I”-Window as a port of entry, this essay focuses on uncovering the internal profile of Daniel through his first-person visionary report (Dan 7–12). Incorporating a three-world reading strategy, I intentionally foreground the juxtaposition between the world of the text and the world in front of the text (the community of pastors). The idea of cognitive dissonance emerges as I compare the “private Daniel” with the “public Daniel” through textual construction. As a demonstrated example of the “empirics” of engaging text emotively, I seek to appropriate the internal turmoil of Daniel as a result of the impact of the exotic visionary experience upon him to the vulnerability of the pastoral vocation.     

Spontaneous recovery of extinguished fear responses deepens their extinction: a role for error-correction mechanisms

A series of experiments used a within-subject design to study spontaneous recovery of fear responses (freezing) to an extinguished conditioned stimulus (CS) in rats. Experiments 1, 2, 3, and 4 demonstrated that: a remotely extinguished CS elicited more freezing than a recently extinguished one on a common test; that the CS showing recovery underwent greater response loss across additional extinction than the one lacking recovery; and that spontaneous recovery and deepening of response loss survived reconditioning. Experiment 5 demonstrated that an excitor extinguished in compound with a CS showing recovery suffered greater loss than an excitor extinguished in compound with a CS not showing recovery, implying that the differential change is regulated by a common error term. Experiments 6 and 7 demonstrated that extinction of a compound composed of two CSs, one showing recovery and a second lacking recovery, produced greater loss to the CS that showed recovery, implying that the change is also regulated by individual error term.

Relations between symptom severity,illness perceptions,visceral sensitivity,coping strategies and well-being in irritable bowel syndrome guided by the common sense model of illness

Irritable Bowel Syndrome (IBS) is a common condition affecting around 10–20% of the population and associated with poorer psychological well-being and quality of life. The aim of the current study was to explore the efficacy of the Common Sense Model (CSM) using Structural Equation Modelling (SEM) in an IBS cohort. One hundred and thirty-one IBS patients (29 males, 102 females, mean age 38 years) participating in the IBSclinic.org.au pre-intervention assessment were included. Measures included IBS severity (Irritable Bowel Syndrome Severity Scoring System), coping patterns (Carver Brief COPE), visceral sensitivity (Visceral Sensitivity Index), illness perceptions (Brief Illness Perceptions Questionnaire), psychological distress (Depression, Anxiety and Stress Scale), and quality of life (IBS Quality of Life scale; IBS-QoL). Using SEM, a final model with an excellent fit was identified (χ² (8) = 11.91, p = .16, χ²/N = 1.49, CFI > .98, TLI > .96, SRMR < .05). Consistent with the CSM, Illness perceptions were significantly and directly influenced by IBS severity (β = .90, p < .001). Illness perceptions in turn directly influenced maladaptive coping (β = .40, p < .001) and visceral sensitivity (β = .70, p < .001). Maladaptive coping and visceral sensitivity were significantly associated with psychological distress (β = .55, p < .001; β = .22, p < .01) and IBS-QoL (β = –.28, p < .001; β = –.62, p < .001). Based on these findings, we argue that to augment the adverse impact of IBS severity on IBS-QoL and psychological distress, psychological interventions will be best to target the mediating psychological processes including illness beliefs, visceral sensitivity and maladaptive coping.
