Contribution of Peer Deviancy Training to the Early Development of Conduct Problems: Mediators and Moderators

Three variables were tested as moderators of the relationship between peer deviancy training and child antisocial behavior in a longitudinal study of 267 boys and girls from ages 5.3 to 9.3 years. Deviancy training was directly measured by observation of the discourse and play of children with same-gender classmates. Peer deviancy training was significantly related to multi-setting child antisocial behavior from ages 5.3 to 9.3 years. Child impulsivity, poor parental discipline, and peer rejection were all significant moderators of that relationship, even in the context of their direct association with trajectories of antisocial behavior and after controlling for deviant peer affiliation. These moderator effects appeared to be associated with children's increased sensitivity to peer modeling and reinforcement of deviant discourse and play. Not all children are equally affected by peer deviancy training, and an array of intervention strategies are described that may serve to protect children from deviant peer influence.     

The HEXACO Model of Personality Structure and the Importance of the H Factor

We give a brief summary of recent research on the structure of personality characteristics, describing the six‐dimensional ‘HEXACO’ model that has emerged as the most accurate representation of that structure. We then discuss the importance of personality as a predictor of socially important criteria, describing a variety of examples involving the Honesty–Humility (H) factor. The H dimension, alone or in combination with other factors of the HEXACO model, is related inversely to a wide array of criteria, including criminal activity and other unethical behaviors as well as materialistic and power‐seeking tendencies.     

The Dutch HEXACO Personality Inventory: psychometric properties, self-other agreement, and relations with psychopathy among low and high acquaintanceship dyads

The HEXACO model (Lee & Ashton, 2004, 2006) of personality structure is based on 6 dimensions that have been recovered in lexical studies of personality in various languages. In this study, we examined a Dutch version of the HEXACO Personality Inventory (HEXACO-PI; Lee & Ashton, 2004) and found it to have satisfactory psychometric properties. Additionally, we examined the level of self-other agreement for the HEXACO-PI variables and the relation of HEXACO-PI Honesty-Humility with the Self-Report Psychopathy Scale (Williams, Paulhus, & Hare, 2007) at varying levels of self-other acquaintanceship. Self-other agreement was found to be high, especially among dyads with high levels of acquaintanceship. Self-reported and other-reported Honesty-Humility and Emotionality were the strongest predictors of psychopathy. The relation between other-reported Honesty-Humility and self-reported psychopathy was near zero for dyads with low levels of acquaintanceship but was moderately strong for dyads with high levels of acquaintanceship.     

The effects of a target–stimulus reminder on performance in a novel object recognition task

The effects of original training-stimulus pre-test reminders were examined in a novel object recognition (NOR) task. NOR is a task that examines memory for complex stimuli, and is driven by the rats’ tendency to spend significantly more time exploring novel objects over those previously experienced. In this task, a delay is imposed between a training experience during which the animal is allowed to investigate a set of identical objects, and a later test exposure where the animal encounters one of the original objects and a novel object with which it has had no previous experience. Experiment 1 demonstrated that performance at 24 h is significantly worse than at an immediate delay (1 min). In the second experiment, it was demonstrated that neither a 10-s nor a 30-s reminder treatment, in the absence of training, resulted in a level of preference for novelty, a measure of memory for the original object, that was significantly greater than chance. Experiment 3 illustrated significant performance effects of a 30-s training stimulus reminder administered 15 min prior to test with a 24-h retention interval. The final experiment illustrated that the additional 30-s of object exposure is effective in enhancing performance only if it occurs shortly prior to test. Animals receiving the additional 30-s immediately following training did not experience such beneficial effects. It was concluded, based upon these results, that pre-test training-stimulus reminders in this task produce effects similar to those seen in more traditional tasks of learning and memory.     

Threshold adjustment in response to asymmetric loss functions: The case of auditors’ “substantial doubt” thresholds

Thresholds play a critical role in linking judgments and choices. One way they do so is by dividing a continuous judgment variable, such as probability, into two regions that imply different choices and actions, such as operate/do not operate, admit/do not admit, or invest/do not invest. We examine this link by focusing on the tendency of professional decision makers to adjust their thresholds when the risks associated with negative decision outcomes are elevated. We report two studies involving experienced auditors that investigate thresholds in a “going-concern” setting. In this setting, the auditor assesses the probability that a business firm will be unable to continue in existence for the coming year; if that probability exceeds a “substantial doubt” threshold (also assessed by the auditor), the auditor is required to disclose the relevant information in the firm’s annual report to the public. Our studies use two experimental cases based on actual business firms that differ in their objective likelihoods of not continuing as going concerns. We derive the auditors’ substantial doubt thresholds from the relationship between their probability assessments and their disclosure choices, unlike all prior research which has simply asked auditors to state the probability they believe represents substantial doubt. We find that auditors’ derived thresholds are adjusted downward for the more problematic firm, a result that we attribute to the asymmetric loss functions inherent in going-concern settings. The second study has some of the auditors directly provide their substantial doubt thresholds (SDTs). The downward adjustment is again found for derived thresholds but not for elicited thresholds, suggesting that the method of capturing thresholds may be an important issue in understanding judgment and choice.     

Conservatism,Locus of Control and Life Satisfaction: A Person/Environment Fit Analysis

Pettigrew's (1958) hypothesis that quality of psychological adjustment is partly a function of the fit between a person's political values and those of the surrounding social milieu was tested using student samples from Queensland and South Australia. The measures of psychological adjustment were two factors of locus of control (political and general) and general life satisfaction. As predicted, in the Queensland sample conservatism was positively associated with higher general life satisfaction while this correlation was reversed for the South Australian sample. Results for the locus of control measures failed to support the hypothesis. The results provided support for the general Person/Environment fit model and indicated the feasibility and value of studying regional differences in Australia.     

Tactile spatial ability: Lateralized performance of deaf and hearing age groups

Hearing adults, 8- and 6-year-old children, together with deaf 9-year-old children, were tested on a unimodal haptic matching task. One additional group of adults was tested with a shorter stimulus presentation time. Data indicated that left-hand superiority was most evident in the performances of the older hearing children, and of the adults with the shorter presentation time. Hemispheric specialization was less noticeable for the younger hearing group, but the task may have been too difficult. A slight right-hand superiority was found in the performance of adults with long presentation time. This may reflect the simplicity of the task for these subjects. Deaf children did not show any clear hand differences, but were superior in overall performance to hearing children.     

A developmental study of the influence of cognitive activity on an ongoing manual task

The present study investigated developmental changes in the lateralized effects of concurrent cognitive activity on the performance of a manual task. Children aged 9, 10, 11 and 12 years were required to press a key continuously for 15 sec whilst at the same time engaging in three conditions involving cognitive activity (spatial, verbal and mixed spatial-verbal probelem solving) and a control condition. The nature of the concurrent cognitive activity was found to produce differential effects on left- and righthand performance with spatial-cognitive activity being a more effective disruptor of an ongoing, left-handed manual task at the age of 9 years. Above that age verbal and spatial activity appear to have comparable disruptive effects.     

Letter: Square wave stimuli and neonatal auditory behavior: reply to Bench (1973)

The author is in agreement with Bench 1973 that without specific analysis one cannot be certain that the auditory output from a given loudspeaker matches the input to that speaker. However, issue is taken with Bench concerning the results obtained by Ashton 1971.
