When mirrors lie: “Visual capture” of arm position impairs reaching performance

If we stand at a mirror’s edge, we can see one half of our body reflected in the mirror, as if it were the other half of our body, seen “through” the mirror. We used this mirror illusion to examine the effect of conflicts between visually and proprioceptively specified arm positions on subsequent reaching movements made with the unseen right arm. When participants viewed their static left arm in the mirror (i.e., as if it were their right arm), subsequent right-arm reaching movements were affected significantly more when there was conflict between the apparent visual and the proprioceptively specified right-arm positions than when there was no conflict. This result demonstrates that visual capture of arm position can occur when individual body parts are viewed in the mirror and that this capture has a measurable effect on subsequent reaching movements made with an unseen arm. The result has implications for how the brain represents the body across different sensory modalities.     

Early mother-infant interaction and factors negatively affecting parenting

The social information-processing model contributes to identifying the psychological processes underlying the construct "sensitivity" in early mother-child interaction. Negative emotional states associated with inadequate self-regulation in coping with stressors affect the mother's attention skills and the processing of the baby's signals. This leads to less synchronous parental practices, particularly unsatisfactory when the baby is unhappy, or crying because the required self-regulation is not provided. This micro-social research studies the sequential profile of maternal reactions to the baby's positive/neutral vs. difficult behaviours and compares them in two groups of dyads, one with mothers who reported high levels of distress and other negative factors for parenting and another group with low levels. The unfavourable circumstances of the high stress group and their negative effects on interaction were observed in some indiscriminate maternal responses and particularly as they reacted to their baby's difficult behaviour, when the mother's regulatory role is more necessary.     

Christian Affiliation,Christian Practice,and Attitudes to Religious Diversity: A Quantitative Analysis among 13- to 15-year-old Female Students in the UK

Within the context of the “Young People’s Attitudes to Religious Diversity” project at the Warwick Religions and Education Research Unit, this study examines the association between self-assigned Christian affiliation, self-reported Christian practice, and attitudes towards religious diversity among a sample of 5,748 13- to 15-year-old female students attending schools in England, Northern Ireland, Scotland, and Wales. The two hypotheses being tested are that, among female students, nominal Christians do not differ in their attitudes towards religious diversity from unaffiliated students and that church attendance leads to less tolerance of other religious groups. The data partly support the first hypothesis but not the second. Churchgoing Christian female students are more interested in and more tolerant of other religious groups. The data also draw attention to the perceived importance of religious education in schools for shaping views on religion and on religious diversity among unaffiliated students, nominal Christians, and practising Christians. Both the Christian churches and religious education in school seem to have an important part to play in nurturing a tolerant and inclusive religiously diverse society in the UK.     

Curry’s Paradox,Generalized Modus Ponens Axiom and Depth Relevance

“Weak relevant model structures” (wr-ms) are defined on “weak relevant matrices” by generalizing Brady’s model structure ${\mathcal{M}_{\rm CL}}$ built upon Meyer’s Crystal matrix CL. It is shown how to falsify in any wr-ms the Generalized Modus Ponens axiom and similar schemes used to derive Curry’s Paradox. In the last section of the paper we discuss how to extend this method of falsification to more general schemes that could also be used in deriving Curry’s Paradox.     

The influence of number of syllables on word skipping during reading

In an eye-tracking experiment, participants read sentences containing a monosyllabic (e.g., grain) or a disyllabic (e.g., cargo) five-letter word. Monosyllabic target words were skipped more often than disyllabic target words, indicating that syllabic structure was extracted from the parafovea early enough to influence the decision of saccade target selection. Fixation times on the target word when it was fixated did not show an influence of number of syllables, demonstrating that number of syllables differentially impacts skipping rates and fixation durations during reading.

Downward spirals of body surveillance and weight/shape concern among African American and Caucasian college women

Within dominant American culture, females often learn to view themselves from an observer's perspective and to treat themselves as objects to be looked at (i.e., self-objectification), which can result in negative outcomes. Body surveillance (the indicator of self-objectification) has been found to predict concern with weight/shape in predominantly Caucasian samples, but research has not yet examined the potential reciprocal relations between body surveillance and weight/shape concern. Participants were 226 women attending a Midwestern university (70 self-identified as African American and 156 as Caucasian) who provided data at two time points, spaced about 5 months apart. Results revealed that downward spirals of body surveillance and weight/shape concern were apparent for the Caucasian but not the African American women. However, there was evidence that body surveillance helped account for change in weight/shape concern for the African American women.     

Discrepancies between patients' and partners' perceptions of unsupportive behavior in chronic obstructive pulmonary disease

The literature on chronic diseases indicates that partner support, as perceived by patients, contributes to well-being of patients in either a positive or a negative way. Previous studies indicated that patients' and partners' perceptions of unsupportive partner behavior are only moderately related. Our aim was (1) to investigate whether discrepancies between patients' and partners' perceptions of two types of unsupportive partner behavior-overprotection and protective buffering-were associated with the level of distress reported by patients with chronic obstructive pulmonary disease (COPD) and (2) to evaluate whether the direction of the differences between patients' and partners' perceptions was associated with distress (i.e., whether patient distress was associated with greater patient or greater partner reports of unsupportive partner behavior). A cross-sectional study was performed using the data of a sample of 68 COPD patients and their spouses. Distress was assessed using the Hopkins Symptom Checklist-25. Patients' and partners' perceptions of unsupportive partner behavior were assessed with a questionnaire measuring overprotection and protective buffering. Distress was independently associated with patients' perceptions of protective buffering and discrepancies in spouses' perceptions of overprotection. Regarding the direction of the discrepancy, we found that greater partner reports of overprotection as compared with patient reports were related to more distress in COPD patients. Our study showed that patients' distress was associated not only with patients' perceptions, but also with discrepancies between patients' and partners' perceptions of unsupportive partner behavior.     

What's in a word? A parametric study of semantic influences on visual word recognition

To what extent does semantic information play a functional role in visual word recognition? Theories of word recognition vary in the importance assigned to semantic information in visual lexical decision, with past research suggesting that the nature of the foils is a crucial determinant of semantic reliance. Here, we explored the conditions under which semantic variables influence lexical decision. Normal readers performed visual lexical decision tasks in which imageability and semantic priming were manipulated, with nonword foils varying systematically in their orthographic and phonological similarity to the real words. The effects of imageability and semantic priming increased in magnitude as nonword foils became progressively more wordlike. These findings provide a clear illustration of the flexible use of semantic information to support normal visual word recognition.
