Inferring hidden causal structure

We used a new method to assess how people can infer unobserved causal structure from patterns of observed events. Participants were taught to draw causal graphs, and then shown a pattern of associations and interventions on a novel causal system. Given minimal training and no feedback, participants in Experiment 1 used causal graph notation to spontaneously draw structures containing one observed cause, one unobserved common cause, and two unobserved independent causes, depending on the pattern of associations and interventions they saw. We replicated these findings with less-informative training (Experiments 2 and 3) and a new apparatus (Experiment 3) to show that the pattern of data leads to hidden causal inferences across a range of prior constraints on causal knowledge.     

Construct Validity of ADHD-IN,ADHD-HI,ODD toward Adults,Academic and Social Competence Dimensions with Teacher Ratings of Thai Adolescents: Additional Validity for the Child and Adolescent Disruptive Behavior Inventory

Confirmatory factor analysis was used to test the construct validity of an attention-deficit/hyperactivity disorder-inattention, attention-deficit/hyperactivity disorder-hyperactivity/impulsivity, oppositional defiant disorder toward adults, academic and social competence factor model with teacher ratings of Thai adolescents (n = 872) with the Child and Adolescent Disruptive Behavior Inventory. The five-factor model resulted in an adequate fit in an absolute sense (i.e., CFI = .960; TLI = .985; RMSEA = .065; and WRMR = .883). All the items had significant and substantial loadings on their respective factors (i.e., > .78) with the five-factors showing discriminant validity. The five-factor model also resulted in similar results for boys and girls separately as well as younger and older adolescents. The current findings with the teacher version of the measure in conjunction with earlier research with mothers’ and fathers’ ratings of Brazilian, Thai, and American children (Burns et al., Psychological Assessment, 20, 121-130, 2008) and Thai adolescents (Burns et al., Psychological Assessment, 21, 635-641, 2009) provide increasing support for the construct validity of Child and Adolescent Disruptive Behavior Inventory within multiple cultures. Procedures are also outlined to improve the content validity as well as test the construct validity of forthcoming parent and teacher DSM-V ADHD/ODD rating scales.     

Personality and prejudice: Extension to the HEXACO personality model

We modelled the associations between the HEXACO dimensions of personality, Social Dominance Orientation (SDO), Right‐Wing Authoritarianism (RWA) and prejudice towards dangerous, derogated and dissident groups (N = 454 undergraduates). Consistent with a Big‐Five model, low Openness to Experience predicted RWA and therefore dangerous and dissident group prejudice. As predicted, low Emotionality (and Openness) rather than Agreeableness predicted SDO and therefore derogated and dissident group prejudice. Comparison with meta‐analytic averages of Big‐Five data supported expected similarities and differences in the association of Big‐Five and HEXACO models of personality with ideology. Finally, Honesty‐Humility simultaneously predicted increases in RWA but decreases in SDO, and thus opposing effects on prejudice. These opposing effects have gone unidentified in research employing Big‐Five models of personality structure. Copyright © 2010 John Wiley & Sons, Ltd.     

Why do employees undertake creative action?

There is much research identifying factors that lead to a creative outcome, but little on what leads employees to begin the creative process in the first place. This research used semi‐structured interviews with 65 engineers to explore the factors and processes involved in this phenomenon. We found that general work motivation, creativity requirements, cultural support for creativity, time resources, and autonomy were all used as cues in deciding whether undertaking creative action would be worthwhile via judgmental processes of expectancy and instrumentality. We also discovered overlaps with the cognate literatures of organizational citizenship and proactivity and explore these in discussing new areas for research.     

Eye color Predicts Disagreeableness in North Europeans: Support in Favor of Frost (2006)

The current study investigates whether eye color provides a marker of Agreeableness in North Europeans. Extrapolating from Frost’s (2006) research uncovering an unusually diverse range of hair and eye color in northern Europe, we tested the hypothesis that light eyed individuals of North European descent would be less agreeable (a personality marker for competitiveness) when compared to their dark eyed counterparts, whereas there would be no such effect for people of European descent in general. The hypothesis was tested in Australia to provide consistent environmental conditions for both groups of people. Results support the hypothesis. Implications and conclusions are discussed.     

Selective attention in human associative learning and recognition memory

Four experiments examined the role of selective attention in a new causal judgment task that allowed measurement of both causal strength and cue recognition. In Experiments 1 and 2, blocking was observed; pretraining with 1 cue (A) resulted in reduced learning about a 2nd cue (B) when those 2 cues were trained in compound (AB+). Participants also demonstrated decreased recognition performance for the causally redundant Cue B, suggesting that less attention had been paid to it in training. This is consistent with the idea that attention is preferentially allocated toward the more predictive Cue A, and away from the less predictive Cue B (e.g., N. J. Mackintosh, 1975). Contrary to this hypothesis, in Experiments 3 and 4, participants demonstrated poorer recognition for the most predictive cues, relative to control cues. A new model, which is based on N. J. Mackintosh's (1975) model, is proposed to account for the observed relationship between the extent to which each cue is attended to, learned about, and later recognized     

Extinction in human learning and memory

In two experiments, participants were given extinction training in a human causal learning task. In both experiments, three critical experimental cues were paired with different outcomes in a first phase of training and were then extinguished in a second phase. Three control cues were given the same treatment in the first phase of training, but were not then presented in the second phase. Participants' ability to correctly identify the outcome with which each cue had been paired in the first phase was lower for extinguished than for control cues. Causal attributions to the extinguished cues were also lower than those to the control cues, a difference that correlated with outcome memory. These data are consistent with the idea that extinction in causal judgement is due, at least in part, to a failure to remember the cue-outcome relationship encoded in the first phase of training.     

Psychological Emptiness in the Zhuāngzǐ

Three views of psychological emptiness, or xū, can be found in the Zhuāngz?. The instrumental view values xū primarily as a means of efficacious action. The moderate view assigns it intrinsic value as an element of one Zhuangist vision of the good life. The radical view also takes it to be an element of the ideal life, but in this case the form of life advocated is that of the Daoist sage, who transcends mundane human concerns to merge with nature or the Dào. The instrumental and moderate views articulate a relatively commonsensical position, on which the agent continues to pursue at least some characteristically human projects. On the radical view, by contrast, the agent ceases to exercise agency and lives a life hardly recognizable as human. The three views thus signal a tension in Zhuangist ethics, and the unattractiveness of the radical view poses a potential obstacle to the application of Daoist ideas in contemporary ethical discourse. The paper argues that there are principled grounds within Zhuangist thought for detaching the instrumental and moderate views from the radical view and rejecting the latter.     

Invariance and convergent and discriminant validity between mothers' and fathers' ratings of oppositional defiant disorder toward adults, ADHD-HI, ADHD-IN, and academic competence factors within Brazilian, Thai, and American children

Confirmatory factor analysis was used to test the invariance of an oppositional defiant disorder toward adults, attention-deficit/hyperactivity disorder-hyperactivity/impulsivity, attention-deficit/hyperactivity disorder-inattention, and an Academic Competence factor model between mothers' and fathers' ratings within Brazilian (n = 894), Thai (n = 2,075), and American (n = 817) children with the Child and Adolescent Disruptive Behavior Inventory (G. L. Burns, T. Taylor, & J. Rusby, 2001a, 2001b). The results showed invariance of item loadings, intercepts, and residuals, as well as factor variances, covariances, and means between mothers' and fathers' ratings within each sample. Convergent and discriminant validity was also observed for the between-parent factor correlations, thus providing additional support for the construct validity of the Child and Adolescent Disruptive Behavior Inventory. The confirmatory factor analysis invariance procedure provides a much better way to examine between-source ratings of behavior problems in children than do the simple correlation and raw discrepancy score procedures.     

Judgments about judgments: the dissociation of consideration price and transaction commitment judgments

There are many contexts in which people make judgments about prior judgments. For example, Internet shopping bots (e.g., NexTag.com) allow consumers to search for products and, if the price is too high, list a price at which they would consider making the purchase (i.e., base judgment). If the price drops to this level, the vendor generates an e-mail inviting the consumer to execute the transaction at the reduced price (i.e., contingent judgment). The authors show that the consideration price depends on the content of retrieved information, whereas the willingness to execute the transaction at the consideration price depends on the ease-of-retrieving the information. The authors use different offer prices to encourage the consumer to retrieve information consistent with different product quality levels. The authors also select offer prices so that information retrieval is more difficult at moderate offer prices than at high or low offer prices. Accordingly, the authors show that the consideration price increases as the offer price increases, but the willingness to execute the transaction at the consideration price is greater when there are high and low, as opposed to moderate, offer prices.
