Intermodal sensory image generation: An fMRI analysis

Although both imagery and perception may be related to more than one sensory input, and information coming from different sensory channels is often integrated in a unique mental representation, most recent neuroimaging literature has focused on visual imaging. Contrasting results have been obtained concerning the sharing of the same mechanisms by visual perception and visual imagery, in part due to assessment techniques and to interindividual variability in brain activation. In recent years, an increasing number of researchers have adopted novel neuroimaging techniques in order to investigate intermodal connections in mental imagery and have reported a high degree of interaction between mental imagery and other cognitive functions. In the present study the specific nature of mental imagery was investigated by means of fMRI on a more extensive set of perceptual experiences (shapes, sounds, touches, odours, flavours, self‐perceived movements, and internal sensations). Results show that the left middle‐inferior temporal area is recruited by mental imagery for all modalities investigated and not only for the visual one, while parietal and prefrontal areas exhibit a more heterogeneous pattern of activation across modalities. The prominent left lateralisation observed for almost all the conditions suggests that verbal cues affect the processes underlying the generation of images.     

Effects of Decision Training on Decision Making and Performance in Young Tennis Players: An Applied Research

This study examined the effectiveness of a 10-week decision training program on decision making and performance in tennis. Decision training was based on the analysis combining tactical questioning and video feedback about players own actions. A quasi-experimental design with intermediate tennis players (control group, n = 6; experimental group, n = 5) was developed over 18 weeks, divided into 3 phases: preintervention, postintervention, and retention. A total of 13,383 game play actions were analyzed to test differences. Experimental group improves significantly decision making and performance and maintained improvements during the retention phase. Video feedback combined with questioning is recommended to achieve sport expertise.     

Impact of Depression and Anxiety on the Quality of Life of Constipated Patients

Constipation negatively affects quality of life (QOL), however, the specific mechanisms through which this relationship occurs are unclear. The present study examined anxiety and depression as potential mediators of the relationship between constipation severity and QOL in a sample of 142 constipated patients. Results indicated that depression symptom severity mediated the relationship between constipation severity and mental health-related QOL. For patients meeting diagnostic criteria for Major Depressive Disorder, indirect effects were observed in the relationship between constipation severity and both physical and mental health-related QOL. Anxiety did not contribute to this model. Treating depression may be useful in improving QOL in severely constipated patients, which highlights the importance of psychological screening and treatment referrals in primary care settings.     

Psychometric characteristics of the Parenting Scale in a Vietnamese sample

The Parenting Scale (PS) is a well‐established instrument for measuring discipline practices in Western populations. However, whether the PS is a valid and reliable measure in Eastern populations is not known. Thus, this study examined the psychometric properties of the PS in a sample of 433 Vietnamese parents of children aged 2–7 years. Confirmatory factor analyses (CFAs) examined the commonly used Reitman et al.'s two‐factor and Rhoades and O'Leary's three‐factor solutions. Neither factor structure fit the data. An exploratory factor analysis identified a 12‐item one‐factor and 14‐item two‐factor solutions that overlapped substantially with established factor structures. The one‐factor solution reflected Lax/Overreactive parenting and the two‐factor solution consisted of Lax/Overreactive and Hostile subscales. The factor structures were confirmed via multigroup CFA. Internal consistencies were acceptable and ranged between .70 and .85. Each factor was positively associated with parent anger, dysfunctional cognitions about child behaviour, and externalising child behaviour problems. However, when entered simultaneously in a regression, Hostile discipline was not uniquely associated with child behaviour. Overall, results support the potential utility of the 12‐item one‐factor PS as a measure of dysfunctional parenting practices for Vietnamese parents.
