Motor resources in peripersonal space are intrinsic to spatial encoding: Evidence from motor interference

The aim of this study was to explore the role of motor resources in peripersonal space encoding: are they intrinsic to spatial processes or due to action potentiality of objects? To answer this question, we disentangled the effects of motor resources on object manipulability and spatial processing in peripersonal and extrapersonal spaces. Participants had to localize manipulable and non-manipulable 3-D stimuli presented within peripersonal or extrapersonal spaces of an immersive virtual reality scenario. To assess the contribution of motor resources to the spatial task a motor interference paradigm was used. In Experiment 1, localization judgments were provided with the left hand while the right dominant arm could be free or blocked. Results showed that participants were faster and more accurate in localizing both manipulable and non-manipulable stimuli in peripersonal space with their arms free. On the other hand, in extrapersonal space there was no significant effect of motor interference. Experiment 2 replicated these results by using alternatively both hands to give the response and controlling the possible effect of the orientation of object handles. Overall, the pattern of results suggests that the encoding of peripersonal space involves motor processes per se, and not because of the presence of manipulable stimuli. It is argued that this motor grounding reflects the adaptive need of anticipating what may happen near the body and preparing to react in time.     

The Relationship Between Religious Service Attendance and Coronary Heart Disease and Related Risk Factors in Saskatchewan, Canada

Research suggests that attending religious services could provide small yet important protective benefits against coronary heart disease (CHD) and CHD risk factors (e.g., diabetes, hypertension). The extent to which these benefits apply to Canada deserves study because approximately one-third of adult Canadians attend religious services at least monthly. Therefore, the objective of this study is to examine the association between frequency of religious service attendance and prevalence of (1) CHD, (2) diabetes, and (3) hypertension in Canada. We used the Saskatchewan sample (n = 5,442) of the Canadian Community Health Survey (CCHS-4.1) and built multivariable logistic regression models to evaluate associations between religious service attendance and self-reported CHD, diabetes, and hypertension. After controlling for demographic, socioeconomic and health behavior variables, the association between religious service attendance and prevalence of CHD was not significant (OR = 0.82; 95 % CI 0.61–1.11). However, persons who attended religious services more than once a week exhibited lower prevalence odds of diabetes (OR = 0.60; 95 % CI 0.45–0.80) and hypertension (OR = 0.82; 95 % CI 0.68–0.99) compared to persons who attended less than once a year. The findings of this study are the first to suggest religious service attendance may be associated with a lower prevalence of CHD risk factors in Canada.     

Attention biases and habituation of attention biases are associated with 5-HTTLPR and COMTval158met

Fundamental biases in affective information processing are modulated by individual differences in the emotional response to environmental stimuli that may be partly based on the individual’s genetic make-up. To extend prior dot probe studies on attention genetics, we used a visual-search paradigm (VSP) with pictures of angry and happy faces of both sexes as targets, neutral faces as distractors, and a varying set size. Participants were selected a priori depending on their 5-HTTLPR (s/s, s/l, l/l; on a constant rs25531 A-allele background) and COMTval158met (val/val, valmet, met/met) genotypes and were matched for sex and age. We demonstrate a bias towards angry male faces (as opposed to happy male faces) irrespective of 5-HTTLPR genotype in the first experimental block that was maintained during the second experimental block only in carriers of the s-allele, which implies differential habituation processes. While a bias towards angry male faces was observed irrespective of COMTval158met genotype, only individuals with the val/val genotype exhibited a bias towards a happy female face (as opposed to an angry female face). In sum, our results both replicate and extend prior findings in the field of attention genetics and add important pieces of information to the research on attentional biases in emotion processing.     

The Role of Social and Cognitive Processes in the Relationship Between Fear Network and Psychological Distress Among Parents of Children Undergoing Hematopoietic Stem Cell Transplantation

The current study examined whether cognitive and social processing variables mediated the relationship between fear network and depression among parents of children undergoing hematopoietic stem cell transplant (HSCT). Parents whose children were initiating HSCT (N = 179) completed survey measures including fear network, Beck Depression Inventory, cognitive processing variables (positive reappraisal and self-blame) and social processing variables (emotional support and holding back from sharing concerns). Fear network was positively correlated with depression (p < .001). Self-blame and holding back emerged as individual partial mediators in the relationship between fear network and depression. Together they accounted for 34.3 % of the variance in the relationship between fear network and depression. Positive reappraisal and emotional support did not have significant mediating effects. Social and cognitive processes, specifically self-blame and holding back from sharing concerns, play a negative role in parents’ psychological adaptation to fears surrounding a child’s HSCT.     

Comparison of activation level between true and false items in the DRM paradigm

The aim of the present study was to compare the activation levels of true and false memories in the Deese–Roediger–McDermott (DRM) paradigm. For this purpose, we used a lexical decision task (LDT) that can be considered a relative pure measure of activation. Participants had to study a list of words that were semantically associated to a critical non-presented word (CI), and afterwards had to classify the actually studied words, the CI and new words in the LDT. Results indicated that the classification latency of the CI was the same as actually studied words and shorter than new words. The results might be interpreted as evidence that the false and true memory items have the same activation level and that the false memory effect can be based on the indirect activation of the CI at the encoding.     

Selective effects of errorful generation on recognition memory: the role of motivation and surprise

ABSTRACT

The current research examined the effects of errorful generation on memory, focusing particularly on the roles of motivation and surprise. In two experiments, participants were first presented with photographs of faces and were asked to associate four facts with each photograph. On Generate trials, the participants guessed two of the facts (Guess targets) before those correct facts, and another two correct facts (Study targets), were revealed. On the remaining Read trials, all four facts were presented without a guessing stage. In Experiment 1, participants also ranked their motivation to know the answers before they were revealed, or their surprise on learning the true answers. Guess targets were subsequently better recognised than the concurrently presented, non-guessed Study targets. Guess targets were also better recognised than Read targets, and recognition of Study and Read targets did not differ. Errorful generation also increased self-reported motivation, but not surprise. Experiment 2 showed that the results of Experiment 1 can outlive a 20-minute delay, and that they generalise to a more challenging recognition test. Together, the results suggest that errorful generation improves memory specifically for the guessed fact, and this may be linked to an increase in motivation to learn that fact.     

Extending the job design perspective on individual innovation: Exploring the effect of group reflexivity

Extending previous research on group reflexivity as a group level predictor of individual innovation, we examined group reflexivity as a possible moderator of the effect of job control and task complexity on individual innovation. We obtained data on job and group characteristics from 135 members of software development teams; line managers provided ratings on individual innovation. Data were analysed using hierarchical linear modelling. Results lend further support to a positive effect of job design on individual innovation, but no effect was found for group reflexivity. The interplay between job design and group reflexivity reveals a more complex picture. While the positive effect of job control is augmented in the presence of high reflexivity, in contrast, task complexity is negatively associated with innovation in teams with high reflexivity. Results are discussed from a time and cognitive resource perspective. Furthermore, the development of context‐specific models on group reflexivity is proposed.
