Effects of the iodine deficiency on intellectual variables among children

An association between severe iodine deficiency and poor mental development has been found in many studies. We examined the relationship between moderate or mild iodine deficiency and intellectual capacity in order to determine whether problems common to severe iodine deficiency (including mental retardation) also emerge in a more subtle form. We also wished to know whether the classic methodology (comparing iodine-deficient zones with nondeficient zones) is the most adequate, and propose to combine this grouping by zones with urinary iodine presented by individuals in each zone. We measured IQ, manipulative and verbal capacity, attention, visual motor ability and disruptive behaviour, variables that have barely been studied in this kind of investigations. The sample comprised 760 schoolchildren from the province of Jaén (southern Spain). Our results show that children with low levels of iodine intake and with urinary iodine concentration lower than 100 microg/litre had a lower IQ and displayed more disruptive behaviour than children with high levels of the criteria. The other variables were not associated with iodine deficiency.     

Patterns of Parental Rearing Styles and Child Behaviour Problems among Portuguese School-Aged Children

The majority of studies investigating the effects of parental behaviour on the child’s adjustment have a dimensional approach. We identified the existence of various patterns in parental rearing styles and analysed the relationship between different parenting patterns and behavioural problems in a group of school-aged children. A longitudinal, multi-informant study was conducted. The sample consisted of 519 school-aged children from the Portuguese general population. Parental rearing styles were measured using the EMBU-C, a questionnaire that evaluates children’s perception of parental rearing dimensions. The assessment of child behavioural problems included the evaluation of internalizing and externalizing problems, and data from multiple reporters (parents and teacher). One year later, after a school transition, the adjustment of a sub-sample of 220 children was evaluated again. Cluster analysis identified four types of parental rearing styles: low support, supportive-controller, rejecting-controller, and supportive. In both assessment periods, low support and rejecting-controller parenting patterns showed higher levels of behavioural problems than the supportive and supportive-controller parenting patterns. These patterns show significant differences between them regarding behavioural problems and have a higher predictive value regarding externalizing problems (versus internalizing problems).     

The Relationship Between the Fear-Avoidance Model of Pain and Personality Traits in Fibromyalgia Patients

This study examined the relationship between several cognitive-affective factors of the fear-avoidance model of pain, the big five model of personality, and functional impairment in fibromyalgia (FM). Seventy-four FM patients completed the NEO Five-Factor Inventory, the Pain Catastrophizing Scale, the Pain Anxiety Symptoms Scale-20, the Pain Vigilance and Awareness Questionnaire, and the Impairment and Functioning Inventory. Results indicated that the cognitive-affective factors of pain are differentially associated with personality traits. Neuroticism and conscientiousness were significant predictors of pain catastrophizing, and neuroticism, openness, and agreeableness were significant predictors of pain anxiety. Personality traits did not contribute significantly to vigilance to pain. The effect of neuroticism upon pain anxiety was mediated by pain catastrophizing, and neuroticism showed a trend to moderate the relationship between impairment and pain anxiety. Results support the fear-avoidance model of pain. Implications of the findings for the understanding and management of FM are discussed.     

Is reading a feminine domain? The role of gender identity and stereotypes in reading motivation in Chile

Social Psychology of Education - In Chile, as in other countries, there are large gender gaps in reading achievement. One factor that may explain some of these results is male and female...     

Active and passive-touch during interpersonal multisensory stimulation change self–other boundaries

In the “enfacement” illusion seeing an unfamiliar face being touched at the same time as one’s own face evokes changes in self-face recognition. We investigated the contribution of proprioceptive and motor signals derived from self-generated actions in the sensory-driven malleability of self–other boundaries during the “enfacement” illusion. Changes in self-face recognition during active- and passive-touch interpersonal visuo-tactile stimulation were quantified by means of psychophysical and psychometric tasks. Active- and passive-touch evoked comparable changes in the categorical boundaries of self–other distinction, changing the extent to which the other is assimilated into the mental self-representation. Actively touching or simply feeling touch on one’s own face with concurrent observed touch on someone else’s face seems to elicit comparable changes in self-recognition, suggesting that afferent input might be sufficient for updating one’s body-image, although some components of the experience of self-identification seem to be more affected by passive- than by active-touch.     

Fibromyalgia in men and women: comparison of the main clinical symptoms

The prevalence of fibromyalgia (FM) in males is much lower than in women. Thus, current knowledge about the syndrome has been developed from research with women. The aim of the present study is to analyze whether FM manifestations differ as a function of sex. Two clinical groups with FM (21 males and 21 women) and a control group of healthy men (n= 21) participated in the study. Several aspects of pain, sleep, fatigue, psychopathology, emotional distress and functional impact of FM were evaluated with an algometer and questionnaires. The clinical groups showed a significantly greater impairment than the control group in all the self-report measures. However, the FM patients only showed significant differences in the sensibility threshold to the pain, which was lower in the women. In addition, the best predictor of the experience of pain in males was sleep quality, and in the women, catastrofying pain. Our results suggest that the most effective therapeutic strategies to control pain may be different for men and women.     

Does working memory load lead to greater impulsivity? Commentary on Hinson, Jameson, and Whitney (2003)

Previous research by J. M. Hinson, T. L. Jameson, and P. Whitney (2003) demonstrated that a secondary task in a delayed discounting paradigm increased subjects' preference for the immediate reward. J. M. Hinson et al. interpreted their findings as evidence that working memory load results in greater impulsivity. The present authors conducted a reanalysis of the data from J. M. Hinson et al.'s Experiment 1 at the individual-subject level. Difference scores were calculated by subtracting the digit memory load condition from the control condition for k (discounting parameter) and a measure of "erroneous" responses. The results indicated that the secondary task increased random responding, which in turn can account for the increased mean estimates of k. Thus, the data do not support the claim that cognitive load affects impulsivity per se.     

Relationship between dispositional optimism/pessimism and stress coping strategies

Recent studies confirm that dispositional pessimism is related with a worse state of physical health, in comparison with dispositional optimism . The efficacy of stress coping strategies has been considered as a mediating mechanism in this relationship. The aim of the present study is to analyze in a sample of university students (n = 200) the association between dispositional optimism/pessimism and different categories of self-reported somatic symptoms , and evaluate the possible mediation of the stress coping strategies in this relationship. The results indicate that: 1) pessimism is positively related with the report of physical symptoms, whereas optimism is negatively associated to somatic complaints; and 2) this relationship can be mainly explained by the differential utilization of the coping strategy denominated self-criticism (characteristic of pessimism).     

Why do people change in therapy? A preliminary study

Why do people change in therapy? A preliminary study. This work represents the beginning of a new way to study the processes that can explain the therapeutic change. The method used is the observation and analysis of therapeutic sessions directly recorded and developed inside a behavioural approach. The category system tries to carry out a functional analysis of the therapist-client interaction which enables the identification of learning processes that work in clinical setting and explain success in therapy. Outcomes are provisional but show the utility of this initial trend of investigation to the comprehension of clinical phenomenon. Conclusions also emphasize the importance of associative learning processes on the therapeutic change.     

The functioning of central categories Middle Level and Sometimes in graded response scales: does the label matter?

The present study evaluates the extent to which central categories explicitly labeled as being in the middle of the other response categories, specifically Middle Level and Sometimes, function as expected according to the integer scoring system. The assumptions are tested by means of Bock's Nominal Model in two 5-response scales. Results show that the assumption of the ordering of the response categories is met for all the items. The ordering of thresholds is satisfied for all but one item with the central category Middle Level . Results are compared with those obtained when middle categories are not explicitly labeled as being in the middle of the other response categories, as in the case of Not Sure , Undecided or?
