Researchers have argued for more dynamic and contextually relevant measures of regulatory processes in interpersonal interactions. In response, we introduce and examine the effectiveness of a new task, the Parent–Child Challenge Task, designed to assess the self‐regulation and coregulation of affect, goal‐directed behaviour, and physiology in parents and their preschoolers in response to an experimental perturbation. Concurrent and predictive validity was examined via relations with children's externalizing behaviours. Mothers used only their words to guide their 3‐year‐old children to complete increasingly difficult puzzles in order to win a prize (N = 96). A challenge condition was initiated midway through the task with a newly introduced time limit. The challenge produced decreases in parental teaching and dyadic behavioural variability and increases in child negative affect and dyadic affective variability, measured by dynamic systems‐based methods. Children rated lower on externalizing showed respiratory sinus arrhythmia (RSA) suppression in response to challenge, whereas those rated higher on externalizing showed RSA augmentation. Additionally, select task changes in affect, behaviour, and physiology predicted teacher‐rated externalizing behaviours four months later. Findings indicate that the Parent–Child Challenge Task was effective in producing regulatory changes and suggest its utility in assessing biobehavioural self‐regulation and coregulation in parents and their preschoolers.

This analysis of 50 French and Norwegian women in high positions of leadership stresses how gendered relations structuring private and professional lives will vary in different cultures according to their sociohistorical contexts. The specific contexts of two Western European democracies, France and Norway, reveal a number of differences impacting on the careers and the construction of the personal and social identities of women leaders. Interviews were held with French women who (a) assumed pioneering leadership positions in the 1970s ( n = 10) and (b) who followed in the 1980s ( n = 20) and with Norwegian women leaders ( n = 20). Sixty percent of the total sample had held posts as cabinet or subcabinet ministers. Illustrations from their narratives, collected through semistructured interviews about their personal and professional itineraries, are used to discuss a number of questions from a comparative cultural perspective: the sense of double marginality, extraneity, lack of entitlement and vulnerability; role-model legitimation; feminism and the women's movement; political parity/mixity; gender consciousness and solidarity; and family and female–male interactions.  相似文献

Functional communication training (FCT) is an evidence-based treatment for behavior targeted for reduction that often combines extinction for target responses and arranges functionally equivalent reinforcement for alternative behavior. Long-term effectiveness of FCT can become compromised when transitioning from clinic to nonclinic contexts or thinning reinforcement schedules for appropriate behavior. Such increases in targeted behavior have been conceptualized as renewal and resurgence, respectively. The relation between resurgence and renewal has yet to be reported. Therefore, the present report retrospectively analyzed the relation between renewal and resurgence in data collected when implementing FCT with children diagnosed with developmental disabilities. We found no relation when evaluating all 34 individuals assessed for resurgence and renewal or a subset of individuals exhibiting both resurgence and renewal. These findings suggest that one form of relapse may not be predictive of another form of relapse.  相似文献

Hoarding disorder is a new DSM-5 disorder that causes functional impairment and affects 2 to 6% of the population (Frost and Steketee 2014). The current study evaluated a multiple mediation model with 243 undergraduate women in which indecisiveness (VOCI; Thordarson et al. Behaviour Research and Therapy, 42(11), 1289-1314, 2004) and decisional procrastination (DPS; Mann 1982) mediated the relationship between dimensions of perfectionism (F-MPS-B; Burgess et al. 2016a) and hoarding behavior (SI-R; Frost et al. Behaviour Research And Therapy, 42(10), 1163–1182, 2004) and excessive acquiring (CAS; Frost et al. Annual Review of Clinical Psychology, 8, 219–242, 2012). Multiple mediational analyses indicated a significant indirect effect for decisional procrastination, but not indecisiveness, in mediating evaluative concerns (but not striving) to SI-R Total, SI-R Clutter, SIR Excessive Acquisition, and both CAS subscales. Both mediators were significant pathways between evaluative concerns and SI-R Difficulty Discarding. These findings support a cognitive behavioral model of hoarding, suggesting that evaluative concerns produces problems in decision-making that influence acquisition, discarding, and clutter.  相似文献

Motion-induced blindness (MIB) is the perceived disappearance of a salient target when surrounded by a moving mask. Much research has focused on the role of target characteristics on perceived disappearance by a coherently moving mask. However, we asked a different question: mainly, are there certain characteristics about the mask that can impact disappearance? To address this, we behaviorally tested whether MIB is enhanced or reduced by the property of common fate. In experiments 1, 2, and 3, we systematically manipulated the motion coherence of the mask and measured the amount of target disappearance. Results showed that, as mask coherence increased, perceived target disappearance decreased. This pattern was unaffected by the lifetime of the moving dots, the dot density of the motion stimulus, or the target eccentricity. In experiment 4, we investigated whether the number of motion directions contained in an incoherent mask could account for our findings. Using masks containing 1, 3, and 5 motion directions, we found that disappearance did not increase proportionally to the number of motion directions. We discuss our findings in line with current proposed mechanisms of MIB.  相似文献

Surveys are one of the most popular ways to collect employee information. Because of their widespread use, data quality is an increasingly important concern. The purpose of this paper is to (1) introduce the intra-individual response variability (IRV) index as an easily calculated and flexible way to detect insufficient effort responding (IER); (2) examine the extent to which various IER indices detect the same or different respondents engaging in IER behavior; and (3) investigate relationships between individual differences and commonly used IER indices to better understand systematic and theoretically relevant IER behavior. In a two-part study, 199 undergraduates responded to questionnaires online, and various IER indices were calculated. The IRV index identifies different respondents than other IER indices. Values on the IRV index (as well as other IER indices) are related to scores on theoretically meaningful individual differences in conscientiousness, agreeableness, and boredom proneness. This study provides researchers with a robust, easily calculated, and flexible means for screening questionnaire data for IER behavior. Practical recommendations for finding and making decisions about IER behavior patterns are provided. This study introduces the IRV index, an extension of the long string, used to identify survey research participants who likely engaged in one type of IER behavior. It is also one of the first studies to evaluate the extent to which IER indices identify different respondents as having engaged in IER and provides additional evidence that values on these indices are related to individual differences.  相似文献

Promoting use of farmers’ markets (FMs) is a promising community‐level strategy to increase access to nutritious foods such as fruits and vegetables. Yet, FM shopping among people with Supplemental Nutrition Assistance Program (SNAP) benefits remains low. This research examined predictors of FM shopping among SNAP recipients living within 1 mile of a FM. A cross‐sectional survey of SNAP participants (N = 270) was conducted in 2015 in Cleveland and East Cleveland, OH, USA. Multinomial regression and zero‐truncated Poisson regression analyses were conducted to examine factors associated with FM shopping. Results indicate 48% reported shopping at a FM at least once in the past year, 26% had shopped at a FM before, but not in the last year, and 26% had never shopped at a FM. The multivariable analyses found awareness of FMs and a healthy food incentive program, and four dimensions of healthy food access are significantly associated with FM shopping among SNAP recipients. The food access dimensions included service delivery, spatial‐temporal, personal, and social access. Findings highlight modifiable leverage points for improving the reach of FMs among low‐income populations.  相似文献

Feeling emotionally close to others during social interactions is a ubiquitous and meaningful experience that can elicit positive affect. The present study integrates functional magnetic resonance imaging (fMRI) and ecological momentary assessment (EMA) to investigate whether neural response to social reward (1) is related to the experience of emotional closeness and (2) moderates the association between emotional closeness and positive affect during and following social interactions. In this study, 34 typically developing adolescents (ages 14–18 years) completed a social-reward fMRI task, a monetary-reward fMRI task, and a 2-week EMA protocol regarding their social and affective experiences. Adolescents with greater right posterior superior temporal sulcus/temporoparietal junction (pSTS/TPJ) response to social reward reported greater mean momentary emotional closeness. Neural response to social reward in the right pSTS/TPJ moderated how strongly momentary emotional closeness was associated with both concurrent positive affect and future peak happiness, but in different ways. Although emotional closeness had a significant positive association with concurrent positive affect among adolescents at both high and low right pSTS/TPJ response based on a follow-up simple slopes test, this association was stronger for adolescents with low right pSTS/TPJ response. In contrast, emotional closeness had a significant positive association with future peak happiness among adolescents with high right pSTS/TPJ response, but not among those with low right pSTS/TPJ response. These findings demonstrate the importance of neural response to social reward in key social processing regions for everyday experiences of emotional closeness and positive affect in the context of social interactions.  相似文献

Attention-deficit/hyperactivity disorder (ADHD) is associated with disruptionsin reward sensitivity and regulatory processes. However, it is unclear whether thesedisruptions are better explained by comorbid disruptive behavior disorder (DBD)symptomology. This study sought to examine this question using multiple levels ofanalysis (i.e., behavior, autonomic reactivity). One hundred seventeen children (aged 6 to 12 years; 72.6% male; 69 with ADHD) completed theBalloon-Analogue Risk Task (BART) to assess external reward sensitivity behaviorally.Sympathetic-based internal reward sensitivity and parasympathetic-based regulationwere indexed via cardiac pre-ejection period (PEP) and respiratory sinus arrhythmia(RSA), respectively. Children with ADHD exhibited reduced internal reward sensitivity (i.e.,lengthened PEP; F(1,112)=4.01, p=0.047) compared to healthy controls and werecharacterized by greater parasympathetic-based dysregulation (i.e., reduced RSAaugmentation F(1,112)=10.12, p=0.002). However, follow-up analyses indicated theADHD effect was better accounted for by comorbid DBD diagnoses; that is, childrenwith ADHD and comorbid ODD were characterized by reduced internal rewardsensitivity (i.e., lengthened PEP; t=2.47, p=0.046) and by parasympathetic-baseddysregulation (i.e., reduced RSA augmentation; t=3.51, p=0.002) in response to rewardwhen compared to typically developing youth. Furthermore, children with ADHD and comorbid CD exhibited greater behaviorally-based external reward sensitivity (i.e.,more total pops; F(3,110)= 5.96, p=0.001) compared to children with ADHD only (t=3.87, p=0.001) and children with ADHD and ODD (t=3.56, p=0.003). Results suggest that disruptions in sensitivity to reward may be betteraccounted for, in part, by comorbid DBD.Key Words: attention-deficit/hyperactivity disorder, autonomic nervous system,disruptive behavior disorders, reward sensitivityPowered  相似文献
