Personal mastery predicts pain,stress, fatigue,and blood pressure in adults with rheumatoid arthritis

Among individuals with rheumatoid arthritis (RA), stress-associated disease flare can severely impact well-being. Psychological factors such as personal mastery may buffer an individual from the negative effects of those flares. We tested the hypothesis that a high sense of personal mastery would prospectively predict stress reactivity. Measures of pain, perceived stress, fatigue, and mean arterial pressure (MAP) were collected before, during, and after two interpersonal stressors conducted on 73 individuals with RA. Factor analysis of the personal mastery scale yielded two independent factors: a 5-item “fatalism” component and a 2-item “control” component. Individuals with high fatalism scores reported overall greater joint pain at baseline and those scoring high on control exhibited lower MAP, and reported less stress and fatigue at baseline. After controlling for baseline differences, those high in control exhibited greater MAP increase during stress, and less drop in pain when compared to those low in control. These results suggest that individuals high in control may be more susceptible to the effects of acute stress; however, the overall beneficial aspects of high control outweigh the acute negative effects. Personal mastery may play a role in the experience of pain, stress, and fatigue for people with RA.     

Spontaneous and experimentally induced action planning and coping planning for physical activity: A meta-analysis

ObjectivesThe main objective of this review was to provide summary effects for spontaneous and experimentally induced action planning (AP) and coping planning (CP) for physical activity (PA). These summary effects were then used to test key theoretical postulates using meta-analytic path analysis, and examine possible boundary conditions via moderation analyses.DesignThis review employed a quantitative research synthesis design.MethodUsing the method of Lipsey and Wilson (2001), fixed- and random-effects meta-analysis was performed on over 150 effect sizes from 23 correlational and 21 experimental studies. The method of Viswesvaran and Ones (1995) was used to test two mediation models using the correlational meta-analytic data. Group comparisons and meta-regression were used to test moderation.ResultsAmong the correlational studies, findings indicated a medium-to-large summary effect of spontaneous AP (φ = .41) and CP (φ = .38) on PA. Among the experimental studies, results revealed a small-to-medium summary effect (φ = .24) when comparing all experimental conditions versus all controls and a medium-to-large summary effect (φ = .37) when comparing purely planning conditions versus neutral controls. Support was found for AP and CP as partial mediators in the relation between intention and PA. Numerous significant moderators emerged.ConclusionThis review offers the first meta-analytic estimates of both spontaneous and experimentally induced AP and CP for PA, while supporting the role of both spontaneous AP and CP as mediators in both a multiple and sequential mediation model. Relevant moderators will serve to inform future research in this area.     

Can't See the Forest for the Trees? The Effect of Media Multitasking on Cognitive Processing Style

Media multitasking represents an important aspect of the recent evolution in media consumption habits. While some experimental research exists, it has primarily focused on the detrimental effects of multitasking on task performance. We go a step further by examining the impact of media multitasking on information processing style. Study I demonstrates that media multitasking, compared to sequential media consumption, leads to a more local perceptual processing style. Furthermore, the frequency of media switching predicts the level of perceptual processing. Study II extends these findings by showing that media multitasking also affects conceptual processing style. Specifically, media multitasking leads to lower-level (or more concrete) construal of behaviors in a subsequent task. It further shows that conceptual rather than visual switching between media drives the observed differences in conceptual processing. These findings suggest that, as a growing phenomenon, media multitasking behavior may substantially alter the way media viewers process media content.     

Waldo reveals cultural differences in return fixations

ABSTRACT

Humans routinely perform visual search towards targets to adapt to the environment. These sequences of ballistic eye movements are shaped by a combination of top–down and bottom–up factors. Recent research documented that human observers display cultural-specific fixation patterns in a range of visual processing tasks. In particular, eye movement strategies extracting information from faces clearly differs between Western Caucasian (WC) and East Asian (EA) observers. However, whether such cultural differences are also present for visual scene processing remains debated. To this aim, we recorded the eye movements of WC and EA observers while they were solving visual search problems parametrically varying in difficulty: Where’s Waldo. Both groups had a comparable familiarity with the Waldo books reaching a comparable level of accuracy in target detection. Both cultural groups also showed a comparable temporal effect on inhibition of return, with longer fixation durations when saccades were performed to a return location compared to other locations. Westerners, however, located Waldo faster than Easterners. Interestingly, this modulation of speed was likely related to differences occurring on the low-level mechanisms of spatial inhibition of return, with EA observers returning more often to previously visited locations than the WC observers. This suboptimal eye movement strategy in the Easterners might be engendered by their cultural perceptual bias consisting in? a greater use of extra-foveal information. Overall, our data point towards the existence of a subtle, but significant difference in the processing of visual scenes across observers from different cultures during active visual search.     

A randomised Monty Hall experiment: The positive effect of conditional frequency feedback

The Monty Hall dilemma (MHD) is a notorious probability problem with a counterintuitive solution. There is a strong tendency to stay with the initial choice, despite the fact that switching doubles the probability of winning. The current randomised experiment investigates whether feedback in a series of trials improves behavioural performance on the MHD and increases the level of understanding of the problem. Feedback was either conditional or non-conditional, and was given either in frequency format or in percentage format. Results show that people learn to switch most when receiving conditional feedback in frequency format. However, problem understanding does not improve as a consequence of receiving feedback. Our study confirms the dissociation between behavioural performance on the MHD, on one hand, and actual understanding of the MHD, on the other. We discuss how this dissociation can be understood.     

Beyond sexual recidivism: A review of the sexual criminal career parameters of adult sex offenders

The current study claims that measures of sexual recidivism provide a distorted view of the criminal activity of adult sex offenders. To address this important limitation, the criminal career perspective is presented and key concepts are defined and described. The study also provides an up-to-date review of the scientific literature on various criminal career parameters of the sexual criminal activity of adult sex offenders. Hence, current empirical knowledge on the prevalence, age of onset, frequency, continuity, versatility, and desistance from sex offending is presented. The findings highlight the complexities of the sexual criminal career of adult sex offenders, and most importantly, its dynamic aspect, both of which are not captured by traditional measures of sexual recidivism. The review also underscores the importance of recognizing that sexual offending develops according to a series of stages, that, if not recognized, may lead to the underestimation of risk for some and over-estimation of risk for others. The review provides a framework to stimulate new areas of research as well as policy-development that is not limited to the identification of the “high-risk” convicted sex offenders.     

Disability Cosmology: The Practice of Making Disability Worlds

The practice of making disability worlds is investigated both theoretically, in the context of developments in disability studies, in particular in the cultural model of disability, and practically in two examples, namely inclusive education environments and public environments. Theoretically, we argue that disability worlds can be better understood by introducing the notion of disability cosmology as the largest possible perspective on the making of disability worlds. A cultural model research perspective of disability consists then of the complementary study of disability identity, culture and cosmology. The practical examples work out the particularities of making and understanding disability worlds. In the making of disability worlds, much attention goes to the ways in which disability worlds relate to the normative world; for example in the formation of boundaries and transgressions, but also fundamentally how disability adds to becoming human.     

Objective age-of-acquisition (AoA) norms for a set of 230 object names in French: Relationships with psycholinguistic variables,the English data from Morrison et al. (1997), and naming latencies

Picture naming speed is strongly influenced by the age of acquisition (AoA) of words. Most studies of AoA have relied on adults' AoA ratings. However, objective AoA has been found to be a stronger determinant of picture naming latencies. Whereas objective AoA norms for words have been collected for some language communities, no objective AoA measures for words were previously available in French. The study provides objective AoA norms for a set of 230 object names following the procedures used by Morrison, Chappell, and Ellis (1997) to collect objective AoA measures in English. The relationships between objective AoA measures, rated AoA, other variables used in psycholinguistic experiments (name agreement, image agreement, conceptual familiarity, etc.), the English data collected by Morrison et al., and naming latencies are analysed and discussed. In addition, reanalyses of data on picture naming latencies (Bonin, Chalard, Méot, & Fayol, 2002) with the use of objective AoA norms are provided. Stepwise multiple analyses show that objective AoA is a stronger determinant of (spoken and written) naming latencies than rated AoA, whereas objective word frequency is not a reliable independent determinant and does not interact reliably with AoA in any of the analyses.     

Multiple schedules of conjugate reinforcement and extinction: A translational model for assessing automatically reinforced behavior

This study evaluated the extent to which a conjugate reinforcement schedule (CONJ) involving a contingency between pedaling a stationary bike and viewing a preferred movie could serve as a translational preparation for the analysis of automatically reinforced behavior. In part, researchers examined whether providing participants with either an accurate or an inaccurate rule about the extinction (EXT) component of a multiple schedule (MULT) contributed to the development of control by the MULT (CONJ EXT) schedule. Results show schedule control emerged for four of five participants who received the accurate rule and none of the five participants who received the inaccurate rule. In addition, participants who received accurate rules typically increased pedaling during CONJ components that followed two consecutive EXT components, suggesting that they experienced deprivation for audio and visual stimulation generated by pedaling. These preliminary findings suggest that researchers could use this translational preparation to identify matched interventions for some automatically reinforced behavior.
