Subjective randomization in one-and two-person games

Following the study by Rapoport and Budescu (1992), two experiments are reported whose main purpose is to compare the generation of random sequences in one- and two-person games. The first experiment addresses the generation of trinary series in two-person zerosum games with asymmetric players. The second examines the generation of binary series using a between-subjects design, and compares the cognitive processes operating in one- and two-person games. Although both types of games result in similar deviations from randomness, they seem to induce qualitatively different cognitive processes.     

Dimensions of perfectionism and constructive thinking as a coping response

The present study examined perfectionism and general coping ability as assessed by a new measure of constructive thinking. A sample of 77 students completed the Multidimensional Perfectionism Scale (MPS) and the Constructive Thinking Inventory (CTI). The MPS provides measures of selforiented, other-oriented, and socially prescribed perfectionism, while the CTI provides various measures, including summary scores of global constructive thinking, emotional coping, behavioral coping, categorical thinking, personal superstitious thinking, naive optimism, and esoteric thinking. Subjects also completed a measure of depressive symptoms so that we could examine perfectionism and coping independent of current levels of adjustment. The main finding was that socially prescribed perfectionism was associated with less constructive thinking and more negative coping across most of the CTI subscales, and these associations remained significant after removing variance due to levels of depression symptoms. Self-oriented perfectionism was adaptive in that it was associated with active forms of behavioral coping, but it was maladaptive in that it was associated with a form of emotional coping involving reduced self-acceptance. The results are discussed in terms of their implications for the cognitive treatment of perfectionists.

选择性注意和起动效应的反转

利用加外周预提示和不加这种提示的方法直接改变注意焦点的状态,从而观测到起动效应的反转,即不加提示条件下的负起动在加提示的条件下反转为正起动。修正了１９８５年Ｔｉｐｐｅｒ提出的起动效应反转的模型;并且在正起动效应的基础上进一步讨论了选择性注意的功能。     

心理弹性、负性生活事件和抑郁症状的关系：钢化效应和敏化效应

该研究追踪调查汶川地震后1573名青少年,考查心理弹性、生活事件和抑郁症状的关系,以探讨幸存者的心理修复过程。结果表明:（1）心理弹性既能直接预测抑郁症状,也能通过抑郁症状间接影响生活事件;（2）生活事件既能直接预测心理弹性,也能通过抑郁症状间接预测心理弹性;（3）抑郁症状既能直接影响心理弹性,也能通过生活事件间接影响心理弹性。结论：灾后不同特征的青少年心理修复过程不同,存在"钢化效应"和"敏化效应"。     

The spiral of distrust: (Non‐)cooperation in a repeated trust game is predicted by anger and individual differences in negative reciprocity orientation

This study investigated state anger and individual differences in negative reciprocity orientation as predictors of individuals' willingness to cooperate with strangers. In order to observe real behaviour, we used a trust game that was played over six periods. In the trust game, a first player (sender) determines how much of a certain endowment she/he wants to share with a second player (trustee), who then can give something back. We varied whether participants received feedback [feedback (yes, no)] about the trustee's behavioural decision (amount sent back). Supporting our hypotheses, the results suggest that feedback compared with no feedback about the trustee's behaviour increased anger. Specifically, information about low back transfers triggered anger and non‐cooperation in return. Importantly, participants with a strong negative reciprocity orientation reported higher levels of anger and were less willing to cooperate with the trustee compared with those with low negative reciprocity orientation. Moreover, even when anger was low, individuals with a strong negative reciprocity orientation were less willing to cooperate compared with those with a low negative reciprocity orientation. Thus, negative reciprocity orientation seems to arouse a spiral of distrust. Theoretical and practical implications of these findings are discussed.     

Intra-individual variability and psychological flexibility: Affect and health in a National US sample

Intra-individual variability (IIV) and psychological flexibility (PF) in affect both describe affective change over time (i.e., within-person variability). However, IIV and PF might differ from each other and predict different psychological and physical health outcomes. A large sample of adults (n = 793) completed two assessments of daily stress, daily affect, and health over a 10-year interval in The National Study of Daily Experiences (an 8-day daily diary portion of the Midlife Development in the United States study). IIV and PF in affect were modestly reliable within and between assessments. IIV, operationalized as total variability, predicted worse psychological and physical health concurrently and prospectively. PF, operationalized as changes in dimensionality, predicted better psychological and physical health concurrently and prospectively. Other operationalizations of PF were not consistently related to health. Within-person variability in affect could therefore be adaptive or maladaptive depending on how it was defined.     

Examining the within-person effect of affect on daily satisfaction

Assessments of global life satisfaction capture beliefs about overall well-being; state satisfaction assessments focus on short-term or “in-the-moment” appraisals of current life circumstances. Prior research has examined how trait measures of life satisfaction and affect are related at between-person and within-person levels of analysis. At the state level, however, a lack of clarity exists about the nature and magnitude of the association between satisfaction and affect. In a diary study involving assessments of both affect and satisfaction at the daily level (N = 350 with 6024 assessments), we found a consequential effect of affect on state satisfaction due to greater within-person variance over time.     

Predicting jet lag in long-haul cabin crew: The role of illness cognitions and behaviour

Objective: Established risk factors for jet lag are mostly physiological including circadian preference, age, gender, the number of flight zones crossed and to some extent direction of travel. Some research has also highlighted a role for psychosocial factors including sleep, diet and ‘circadian’ health behaviours and illness cognitions although this remains relatively untested. The aim of this study was to evaluate the role of sleep, diet and illness cognitions in predicting perceived jet lag amongst long-haul crew.

Design: Sixty long-haul crew took part in a longitudinal study. Profile characteristics (including chronotype), preparation strategies (sleep, eating and ‘circadian’ behaviours) and illness cognitions were measured at baseline (before a trip).

Main outcome measures: Subjective jet lag (unidimensional and multidimensional) was measured on the crews’ second day off (post-trip).

Results: Hierarchical regression analyses showed that unidimensional jet lag was predicted by the belief in a cyclical timeline, whereas multidimensional jet lag was predicted by multidimensional jet lag at baseline and to a lesser extent by identity. No role was found for profile characteristics and preparation strategies.

Conclusion: Illness cognitions partly explain the experience of perceived jet lag in long-haul cabin crew indicating that jet lag is in part a psycho-social construct, not just a biological one.

Associations of Lifetime Depression with Trauma Exposure,Other Environmental Adversities,and Impairment in Adolescents with ADHD

Depression is a common, potentially devastating comorbidity in youth with attention-deficit/hyperactivity disorders (ADHD). Various environmental adversities are well-described as correlates of depression in general pediatric populations, but not in youth with ADHD. In 104 adolescents with ADHD, we examined potential environmental correlates of lifetime depression, including trauma exposure, recent negative life events and current parent-child conflict, along with current and past ADHD severity and current impairment. Controlling for demographic variables, comorbid disorders, and ADHD severity, we noted significant associations between lifetime depression and environmental adversities, including victimization trauma, parent-child conflict, and behaviorally-independent negative life events. Current impairment but not ADHD severity was also highly associated with lifetime depression, controlling for the same covariates. Findings from this preliminary, cross-sectional study suggest that environmental adversities and impairment in youth with ADHD should also be targeted along with the ADHD when contemplating strategies to treat or prevent comorbid depression.
