On the relation between demographic variables and neuropsychological test performance

This paper reports a study of the relation between demographic variables and neuropsychological test performance in a sample of 141 normal subjects. A preliminary analysis demonstrated the importance of age, educational level, sex, and Verbal IQ for the prediction of neuropsychological test performance. The main study is a detailed analysis of the relation between these four variables and neuropsychological test performance. The results are presented in the form of standardized regression coefficients and are discussed in relation to the problem of predicting expected premorbid performance in neuropsychological tests.     

Age trends in early behavioral predictors of serious antisocial behaviors

A risk group of disruptive boys (N=65) identified in kindergarten was assessed using the same procedures at ages 6–7, 8–9, and 10–11. Criteria used to define the predictors and criterion variable were the same at all assessment times. Severity was addressed by comparing different forms of behaviors, considering the extent of harmful consequences to others (aggressiveness was considered as most harmful, whereas inattention was considered as least harmful), manifestation in multiple settings, and extreme scores (manipulation of cutoff scores). Different assessment strategies (direct observations, ratings) and different informants (trained observers, mothers and teachers) were used. Aggressiveness as rated by mothers was highly stable from age 6 to age 11. Inattention as rated by teachers was stable only from age 6 to age 9, whereas no stability was found for observations of task inappropriate behaviors. Taskinappropriate behaviors observed in mother-child interactions and in multiple settings at age 6–7 were significant predictors of self-reported antisocial behaviors at age 12, but this prediction was not repeated at ages 8–9 and 10–11. Teacher ratings of inattention at ages 6–7 and 8–9 were also significant predictors of self-reported antisocial behaviors at age 12. The predictive power was much lower when mothers' ratings of aggressiveness were used. Findings from the present study support the hypothesis that some antisocial behavior precursors are age dependent, in that they are more characteristic of certain age groups than of others. Implications for the selection of assessment screening procedures are discussed.     

Semantic and episodic predictions of memory for plans1,2,3

Abstract: This study was conducted to investigate the planning process within memory for plans. Experiment 1 examined the effect of self‐involvement on memory for a 1‐day plan, in which approximately half of the 104 undergraduate participants were instructed to assume that the plans were their own while the other half were told only to memorize them. A U‐shaped curve, indicating better recall for morning and evening plans than for afternoon ones, was observed only with the first group. Experiment 2 was designed to further clarify the planning strategies of memory for plans, in which approximately half of the 77 undergraduate participants were asked to imagine executing the plans while the other half were given a more limited strategy. U‐shaped curves were observed in both conditions, with memory performance being higher for the first group. These results are interpreted as indicating that the semantic prediction of future plans conforms to a U‐shaped curve, while the episodic prediction of future plans enhances memory performance.     

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.     

Motivated reasoning in the prediction of sports outcomes and the belief in the “hot hand”

The present paper explores the role of motivation to observe a certain outcome in people’s predictions, causal attributions, and beliefs about a streak of binary outcomes (basketball scoring shots). In two studies we found that positive streaks (points scored by the participants’ favourite team) lead participants to predict the streak’s continuation (belief in the hot hand), but negative streaks lead to predictions of its end (gambler’s fallacy). More importantly, these wishful predictions are supported by strategic attributions and beliefs about how and why a streak might unfold. Results suggest that the effect of motivation on predictions is mediated by a serial path via causal attributions to the teams at play and belief in the hot hand.     

自恋人格调节信任博弈的结果评价

自恋人格个体表现出亲社会行为的减少和对他人的反馈敏感。信任是人类社会互动行为的基础,自恋人格特质可能影响他们的信任决策。为了探究自恋水平如何影响信任博弈中结果评价的大脑活动,本研究采用事件相关电位技术记录了38名被试完成单次信任博弈时的脑电波。行为结果发现相对高自恋者的信任选择率显著低于相对低自恋者的信任选择率。脑电结果表明,相对高自恋者信任损失反馈减互惠获利反馈所得的FRN差异波(d FRN)显著地大于相对低自恋者,并且相对高自恋者结果评价诱发的P300波幅显著地大于相对低自恋者。本研究提供了自恋人格个体信任博弈中结果评价的初步神经电生理学证据。     

Know thy agency in predictive coding: Meta-monitoring over forward modeling

Though the computation of agency is thought to be based on prediction error, it is important for us to grasp our own reliability of that detected error. Here, the current study shows that we have a meta-monitoring ability over our own forward model, where the accuracy of motor prediction and therefore of the felt agency are implicitly evaluated. Healthy participants (N = 105) conducted a simple motor control task and SELF or OTHER visual feedback was given. The relationship between the accuracy and confidence in a mismatch detection task and in a self-other attribution task was examined. The results suggest an accuracy-confidence correlation in both tasks, indicating our meta-monitoring ability over such decisions. Furthermore, a statistically identified group with low accuracy and low confidence was characterized as higher schizotypal people. Finally, what we can know about our own forward model and how we can know it is discussed.

Organizational context and face-to-face interaction: Influences on the development of trust and collaborative behaviors in computer-mediated groups

Using adaptive structuration theory as a framework [DeSanctis, G., & Poole, M. S. (1994). Capturing the complexity in advanced technology use: Adaptive structuration theory. Organization Science, 5(2), 121–147], we examined the influence of organizational context (competitive versus cooperative) and introductory meeting communication medium (face-to-face versus electronic) on the development of trust and collaborative behaviors of dyads communicating electronically. Based on a sample of 208 senior business students operating in computer-mediated (CM) dyads while performing a strategic decision-making simulation, we found that context, introductory communication medium, and time interacted to influence trust and collaborative behaviors. The pattern of development of trust and collaborative behaviors differed for the same introductory communication medium in different context conditions. Further, the level of trust and collaboration for dyad members in the competitive/electronic introductory meeting condition lagged significantly behind those in the other conditions. The findings suggest that introductory face-to-face interaction plays a more important role in facilitating the development of trust and collaboration in a CM environment when the context is competitive.
