The objective of this study was to evaluate gender differences in the pain threshold, considering the type of pressure point, its location and the repetition of the assessment. The pressure pain threshold was evaluated in 30 healthy volunteers (12 men and 18 women) in three assessment sessions separated by 15 min and 7 days, respectively. Each assessment session was in turn composed of two trials in each of which 24 different pressure points (symmetrically located), representing the 18 tender points for the diagnosis of fibromyalgia and six control points, were assessed. Gender differences were found in the pain threshold for all of the points and the measures taken, women showing a lower pain threshold in comparison to men and being these differences more pronounced for control points than for tender points, the former reaching statistical significance in all cases. The analysis of the influence of repeated measures on gender differences in the pain threshold showed a distinct pattern of recuperation in men than in women, although only one difference in pain threshold was significant. The utility of the tender point concept to study gender differences in pain threshold and the mechanisms that may explain different patterns of recuperation between genders are discussed. 相似文献

Executive function and working memory deficits are not only present in ADHD, but also in reading disorder (RD). Here, high-density ERPs were recorded during the Stop Signal Task in 53 children and adolescents: An ADHD-combined type group, a group with RD, and a healthy control group. The ADHD-C group displayed unique abnormalities of the frontal N200. Both healthy controls and RD groups showed a success-related right frontal N200 modulation, which was absent in the ADHD group. Second, for Success Inhibition trials, the ADHD-C had smaller right frontal N200 waves relative to healthy controls, while the RD group did not. In contrast, NoGo-P3 abnormalities were present both in the ADHD-C and RD groups. Impaired early response inhibition mechanisms, indexed by the frontal N200, appear to be limited to ADHD-C. In contrast, deficits in later cognitive control and error monitoring mechanisms, indexed by the NoGo-P3, appear to be present in both conditions. 相似文献

It has been proposed that abusive parents and parents at high risk for child physical abuse could be more likely to view children's behavior as being motivated by hostile intent [e.g., Milner, 1993], as compared to nonabusive and low‐risk parents. This kind of misattribution of other's behavior may inhibit empathic emotion, and therefore, could block the inhibiting effect of a victim's pain cues on aggression [Baron, 1979]. An experiment was designed to analyze the moderating effect of an adult victim's intent on aggression in high‐ and low‐risk participants for child physical abuse. A 2 × 2 factorial design based upon two levels of the participant's risk status (high, low) and two levels of victim's intent (positive, ambiguous) was employed. All participants observed an adult victim's pain cues. Ninety‐five (48 high and 47 low risk for child physical abuse) undergraduate females enrolled in courses at the University of the Basque Country participated in the experiment. The main effects of victims' intent and of participants' risk status were statistically significant. Participants in the ambiguous victim's intent condition aggressed significantly more than participants in the positive victim's intent condition. Moreover, high‐risk participants aggressed more than low‐risk participants regardless of the victim's intent. A significant interaction between risk status and victim's intent was expected. High‐risk subjects for child physical abuse were expected to aggress more than low‐risk subjects only in the ambiguous victim's intent condition. However, results did not support this hypothesis.

Coparenting Profiles in the Context of Mexican‐Origin Teen Pregnancy: Links to Mother–Daughter Relationship Quality and Adjustment 下载免费PDF全文

The current study explored the multifaceted nature of the mother–adolescent coparental relationship with data from 167 Mexican‐origin adolescent mothers and their own mothers at 10 months post childbirth. Profiles of mother–adolescent coparenting were created with latent profile analysis using adolescents’ reports of three dimensions of coparenting (communication, involvement, and conflict). Four profiles were identified: (a) Harmonious Coparents (equal involvement, high communication, low conflict); (b) Harmonious‐Adolescent Primary (adolescent is more involved than mother, high communication, low conflict); (c) Conflictual Coparents (equal involvement, high communication, high conflict); and (d) Conflictual‐Adolescent Primary (adolescent is more involved than mother, moderate communication, high conflict). Families characterized by high mother–daughter conflict and psychological control prior to childbirth were more likely to belong in the Conflictual Coparents profile. In addition, adolescents’ and mothers’ depressive symptoms and parenting efficacy after childbirth were linked to profile membership, such that the Harmonious‐Adolescent Primary profile reported the most positive adjustment patterns, whereas profiles with high coparental conflict (i.e., Conflictual Coparenting and Conflictual‐Adolescent Primary profiles) showed the least positive adjustment patterns. Discussion considers the applied implications of identifying precursors to healthy and problematic mother–daughter coparenting for families of adolescent mothers in the early years of parenting. 相似文献

OBJECTIVE: Evidence indicates that depression is linked to the development and worsening of diabetes, but the mechanisms underlying this link are not well understood. The authors examined the hypothesis that diabetes-related symptoms mediate the effect of both behavioral adherence and body mass index (BMI) on depression. In addition, they examined whether a prior finding that self-efficacy mediates the effect of behavioral adherence and BMI on depression would replicate with a larger sample size (W. P. Sacco, K. J. Wells, C. A. Vaughan, A. Friedman, S. Perez, & R. Morales, 2005). Also, the relative contributions of diabetes-related symptoms and self-efficacy to depression were evaluated. DESIGN AND PARTICIPANTS: Cross-sectional design involving adults diagnosed with Type 2 diabetes (N = 99). MAIN OUTCOME MEASURES: The primary outcome measure was depression (Patient Health Questionnaire: Nine Symptom Depression Checklist). Predictors of depression were diet and exercise adherence (Summary of Diabetes Self-Care Activities Questionnaire), diet and exercise self-efficacy (Multidimensional Diabetes Questionnaire), diabetes symptoms (Diabetes Symptom Checklist), and BMI (based on height and weight data from medical records). RESULTS: Path and mediation analyses indicated that adherence and BMI each contributed to depression indirectly, via their effects on self-efficacy and diabetes-related medical symptoms. CONCLUSION: Results provide evidence consistent with two independent pathways by which BMI and adherence could increase depression in people with Type 2 diabetes. The first pathway indicates that the effects of higher BMI and poor adherence on depression are mediated by lower self-efficacy perceptions. The second pathway indicates that the effect of higher BMI on depression is mediated by increased diabetes symptoms. 相似文献

We assume that executive function constitutes an integrated set of cognitive processes that mediate working memory, planning, inhibition, flexibility, and decision making. Despite the acknowledged theoretical connection between executive function processes and emotional intelligence, such relationships have rarely been investigated. The purpose of this study was to examine the potential relationship between constructive thinking, conceived as a component of emotional intelligence, and executive function, as indexed by various existing neuropsychological and experimental instruments. We used the Constructive Thinking Inventory as a measure of emotional intelligence. We found that some constructive thinking subscales were able to predict distinct executive function variables. Emotional Coping, Categorical Thinking, and Esoteric Thinking subscales explained performance on various measures of executive function. Thus, we conclude that intervention programs designed to train a specific component of emotional intelligence, namely constructive thinking, could also facilitate performance in executive function processes, and vice versa.

There is a large body of evidence suggesting that words learnt early in life are recognised and produced faster than words learnt later in life, even when other variables are controlled. This is known as the Age of Acquisition (AoA) effect. However, there is an aspect of AoA that requires research of a greater depth, namely the method of obtaining the AoA measures. In the majority of studies, adult participants were asked to estimate the age at which they learnt a given word. Morrison, Chappell, and Ellis (1997) proposed a new method for obtaining objective-AoA data. They asked children to name some objects, and the age at which a given word appeared with 75% or more frequency was considered the AoA of that word. Although this method is more valid than adult ratings, it has only rarely been used. The main aim of this work is to provide objective-AoA norms in Spanish for a set of 175 object names following the procedures used by Morrison et al. The relationships among objective-AoA, estimated-AoA, and other psycholinguistic variables (name-agreement, familiarity, visual complexity, word length, etc.) obtained from a previous study are also analysed. Finally, the similarity of objective- and estimated-AoA measures was examined using data from several languages. A cluster analysis and a multidimensional-scaling analysis revealed that the estimated-AoA measures in a language correlated more with the estimated-AoA measures of the other languages than with the objective measures in the same language. The results suggest that it would be desirable to always use objective-AoA norms because they are less skewed by familiarity. 相似文献
