Self-control and impulsiveness in children and adults: Effects of food preferences

Experiment 1 used 6 preschool boys and Experiment 2 used 6 adult women to explore the effects of food preference on humans' choice in self-control paradigms. The boys showed a higher proportion of responses for more delayed, larger reinforcers (a measure of self-control) when those choices resulted in receipt of the most preferred food compared to when those choices resulted in the least preferred food. Further, the boys chose the less delayed, smaller reinforcers significantly more often when only those choices, as opposed to both choices, resulted in the most preferred food. Conversely, they chose the more delayed, larger reinforcers significantly more often when only those choices, as opposed to both choices, resulted in the most preferred food. Finally, the women demonstrated significantly less sensitivity to reinforcer amount relative to sensitivity to reinforcer delay (another measure of self-control) when they had a higher preference for the juice received as the less delayed, smaller reinforcer than for the juice received as the more delayed, larger reinforcer. Together, the results show that subjects' food preferences can influence self-control for food reinforcers.     

Gender, Somatization, and Psychopathic Traits in a College Sample

The structure of psychopathic traits and their association with somatization symptoms were investigated in a sample of 199 undergraduate college students enrolled in introductory psychology classes. Using multiple measures of psychopathic traits, an iterated principal axis (IPA) analysis revealed two dimensions of psychopathy that were similar to ones typically found in forensic samples. One dimension focused on a cold, callous, and unemotional interpersonal style and the second dimension focused on an impulsive and antisocial lifestyle. These two dimensions emerged for both men and women, although the correlation between the two was somewhat higher for men than women. Also, the callous and unemotional dimension was negatively correlated with somatization symptoms, and the impulsive and antisocial dimension was positively associated with somatization symptoms. This pattern of associations was similar for both men and women and it suggests that somatization symptoms may be one aspect of the high rate of negative affectivity experienced by antisocial individuals.     

Do aggressive driving and negative emotional driving mediate the link between impulsiveness and risky driving among young Italian drivers?

ABSTRACT

The present study examined the contribution of impulsiveness and aggressive and negative emotional driving to the prediction of traffic violations and accidents taking into account potential mediation effects. Three hundred and four young drivers completed self-report measures assessing impulsiveness, aggressive and negative emotional driving, driving violations, and accidents. Structural equation modeling was used to assess the direct and indirect effects of impulsiveness on violations and accidents among young drivers through aggressive and negative emotional driving. Impulsiveness only indirectly influenced drivers’ violations on the road via both the behavioral and emotional states of the driver. On the contrary, impulsiveness was neither directly nor indirectly associated with traffic accidents. Therefore, impulsiveness modulates young drivers’ behavioral and emotional states while driving, which in turn influences risky driving.     

越老越风险规避吗？——年龄对冲动性预测决策行为的调节效应

年老化伴随着风险承担倾向的改变,而决策行为受冲动性的影响是否受到年龄的调节尚不清楚。研究采用两种不同类型的决策任务以及Barratt冲动性量表,考察老年人风险承担在自我报告和决策行为上的改变。结果显示老年人在剑桥博弈任务中更加风险寻求而在模拟充气球任务中更加风险规避。同时冲动性可以显著预测模拟充气球的行为,且该预测受到年龄的调节。研究结果提示,老年人并不是单一的更加风险规避或者风险寻求,而是与任务特异性相关。同时,冲动性可以较好的预测年轻人的决策行为,而对老年人的决策行为没有预测作用。     

The relation between scores on the Buss–Perry Aggression Questionnaire and aggressive acts,impulsiveness, competitiveness,dominance, and sexual jealousy

This paper examines the relation of the four subscales (physical, verbal, anger and hostility) of the Buss–Perry Aggression Questionnaire (BPAQ) to act‐based aggression questionnaires (involving same‐sex or partners as opponents, and direct or indirect aggression) and evolutionarily based predictors of aggression, using an online student sample. All aggression measures were moderately correlated with one another. The BPAQ physical and verbal scales were most closely related to act‐based measures of direct aggression to a same‐sex other and the hostility scale to indirect aggression to a same‐sex other. The evolutionary variables were less closely related to the BPAQ than were the act‐based measures. Dominance and sexual jealousy were predictors of BPAQ physical, verbal and anger, and impulsiveness was a significant predictor of anger. Aggr. Behav. 32:1–10, 2006. © 2006 Wiley‐Liss, Inc.     

Two-Mode Models of Self-Regulation as a Tool for Conceptualizing Effects of the Serotonin System in Normal Behavior and Diverse Disorders

ABSTRACT— The serotonin system is a collection of neural pathways whose overall level of functioning (from low to high) relates to diverse kinds of psychological and behavioral variability. Individual differences in serotonergic function are important both in personality and in vulnerability to psychological disorders. These disorders range widely—from impulsive aggression to depression. One way to understand such diverse reflections of differences in serotonergic function is by viewing serotonergic function through the lens of two-mode (or dual-process) models of self-regulation. Such theories posit a lower-order system that responds quickly to associative cues of the moment and a higher-order system that responds reflectively and planfully. Low serotonergic function appears to enhance influence of the lower-order system. This often yields impulsive reactivity. Why, then, does low serotonergic function also relate to depression, which is characterized by lethargy and unresponsiveness? The answer must be that ascendance of the lower system interacts with other factors. One hypothesis is that low serotonergic function plus high sensitivity to incentives yields vulnerability to impulsive approach, whereas low serotonergic function plus low incentive sensitivity yields vulnerability to depression. Conceptualizing serotonergic function this way helps integrate information pertaining to very different disorders into a coherent picture.     

冲动性人格、亲子沟通对青少年网络成瘾的交互作用分析

本研究通过对1610名初一至高三学生的问卷调查,考察了冲动性人格、亲子沟通对青少年网络成瘾的交互影响。经过方差分析、相关分析和回归分析的结果表明：（1）与非网瘾青少年相比,网瘾倾向青少年的行动冲动性和无计划冲动性显著更高,与父亲和母亲的沟通都更差;（2）行动冲动性、认知冲动性和无计划冲动性均与青少年网络成瘾成显著正相关,而父子沟通和母子沟通均与青少年网络成瘾成显著负相关;（3）行动冲动性和无计划冲动性可正向预测青少年网络成瘾,但认知冲动性的预测作用不显著;母子沟通可负向预测青少年网络成瘾,但父子沟通的预测作用不显著;（4）行动冲动性和母子沟通对青少年网络成瘾存在交互影响,具体而言,对于低行动冲动性青少年而言,母子沟通对其网络成瘾具有显著的负向预测效应;但对于高行动冲动性青少年而言,母子沟通对其网络成瘾具有正向但不显著的预测作用。     

The measurement of cognitive impulsiveness: Psychometric properties of two automated adult versions of the Matching Familiar Figures Test

An automated version of the Matching Familiar Figures Test (MFFT) was administered to undergraduates, along with a parallel from. The latency-errors correlation (–0.61) was higher than that reported for most studies in children and weakly supports the view that the correlation increases with age. Repeated exposure resulted in improved performance, which was faster, more accurate, and more efficient, but there was no effect on impulsiveness. Reliability and internal consistency of both forms were acceptably high and the forms were comparable. Use of the univariate measures (impulsiveness-reflectiveness and efficiency-inefficiency) is superior to other scoring methods.Supported in part by a grant from the Nuffield Foundation, England.     

The Children's Dual Emotion Regulation Strategy scale: An integrated perspective of Western and East Asian cultures

The literature on emotion regulation in general lacks cultural and contextual sensitivity and is mainly focused on adult participants. Therefore, we developed the Children's Dual Emotion Regulation Strategy (CDERS) scale as a scenario-based measurement that integrates Western and East Asian cultural perspectives. In Study 1 (N = 1120), six interpersonal conflict scenarios were generated, and each scenario consisted of four emotion regulation strategies (i.e., expression, forbearance, impulsiveness, and suppression), thereby including 24 items in total. A confirmatory factor analysis confirmed the four-factor structure. Concurrent validity revealed that the four strategies in the CDERS accounted for 18%–20% of the variance in predicting positive self-concept and life adjustment. In Study 2 (N = 319), predictive validity revealed that CDERS accounted for 12%–16% of the variance in predicting six outcomes. Incremental validity showed that the CDERS significantly accounted for an additional 3%–11% of the variance in predicting all outcomes above and beyond the existing Western and East Asian emotion regulation measures. The CDERS subscales showed acceptable internal and test–retest reliability. In summary, these studies suggest that the CDERS is a reliable and valid measure. The implications of the results point out suggestions for culturally sensitive practices.
