Commentary on the Multimodal Treatment Study of Children with ADHD

The multimodal treatment study of attention deficit hyperactivity disorder (MTA Study) constitutes a landmark in the history of treatment research in child psychopathology, being the largest single study of its kind ever undertaken. Important findings have emerged from this project, as the papers in the present volume will attest. This commentary focuses on several concerns about the assumptions that appear to have guided the design of the MTA study, particularly its psychosocial treatment component, as well as the manner in which treatment results have been presented to date. In particular, no explicit theory of ADHD appears to have guided the construction of the treatment components, relying instead on implicit theories associated with those treatments, such as the notion that the symptoms of ADHD arise through faulty learning and defective contingencies of reinforcement. Future articles from this study will need to address these and other concerns if the results of the study are to be properly interpreted and the scientific and clinical yield is to be maximized.     

Multimethod Psychoeducational Intervention for Preschool Children with Disruptive Behavior: Two-Year Post-Treatment Follow-up

This paper describes the 2-year post-treatment follow-up of preschool children identified as having high levels of disruptive behavior at kindergarten entry. They were assigned to four treatment conditions: A no-treatment group, parent-training only, treatment classroom only, and the combination of parent training with the treatment classroom. Interventions lasted the entire kindergarten academic year. Initial post-treatment results reported previously indicated no effects for the parent-training program but some efficacy for the classroom intervention program. For this report, the disruptive behavior (DB) children were subdivided into those who did (n = 74) and did not (n = 77) receive the treatment classroom. Two-year post-treatment follow-up results indicated no differences between the classroom treated and untreated DB groups. These groups also failed to differ in the percentage of children using available treatments across the follow-up period. The DB children in both groups had significantly more symptoms of ADHD and ODD than a community control group (N = 47) at follow-up. They also received higher ratings of externalizing problems on the parent Child Behavior Checklist, more severe ratings of behavior problems at home, and ratings of more pervasive behavior problems at school, and had poorer academic skills. Results suggested that early intervention classrooms for DB children may not produce enduring effects once treatment is withdrawn, and that better approaches are needed for identifying those DB children at greatest risk for later maladjustment.     

Testing the aesthetic significance of the golden-section rectangle

The aesthetic significance of the golden-section rectangle was tested in two studies designed to obviate some of the criticisms of earlier experiments. In the first, employing the method of use, the mean sides-ratios of samples of paintings from five subject-matter categories (landscape, still life, head-and-shoulders portrait, upper-body portrait, full-length portrait) provided no evidence for the significance of the golden section. However, the sides ratio of portraits varied between categories in ways that were consistent with the requirements of the proportions of the subject matter. In the second study, using the method of production, participants produced the most pleasing four-sided shape, under four instruction conditions. Under a 'portrait painting' condition and a 'landscape painting' condition, the mean sides-ratios differed significantly from the golden section. Under two 'context free' geometric shape conditions--horizontal rectangle and vertical rectangle--the mean sides-ratio approximated the golden section. The results are discussed in terms of the methodological requirements for a valid test of the aesthetic significance of the golden section and the possibility that this ratio may indeed have special significance.     

A Brunswikian evolutionary-developmental theory of adolescent sex offending

A Brunswikian Evolutionary-Developmental model was developed to relate the sex offending behavior of adolescents to other forms of social deviance, tracing a history of repeated frustration and failure in various competitive sexual strategies and escalation to more extreme means of obtaining sexual gratification. Four hypothetical constructs were proposed as stages in the development of sexual criminality: (1) Psycho-Social Deficiency (PSD); (2) Non-Criminal Sexuality (NCS); (3) Non-Sexual Criminality (NSC); and (4) Sexual Criminality (SC). Significant direct and indirect pathways led from PSD to SC through both NCS and NSC, each time facilitated by an interaction with PSD. Although the causal orders between stages remain equivocal, the current results are consistent with our theory and establish the heuristic value of our theoretical approach, providing empirical support for otherwise counterintuitive predictions. This interpretation also offers hope for focusing preventative intervention at one major root cause of this unfortunate cascade of consequences, Psycho-Social Deficiency.     

Malicious pleasure: schadenfreude at the suffering of another group

Two studies examined intergroup schadenfreude--malicious pleasure at an out-group's misfortune. Study 1 showed that schadenfreude regarding a German loss in soccer was increased by interest in soccer and threats of Dutch inferiority. The effect of inferiority threat was especially strong for participants less interested in soccer; the more interested showed relatively high schadenfreude. Study 2 replicated these effects by showing a similar pattern of schadenfreude regarding losses by Germany and Italy in another setting. However, schadenfreude toward legitimately superior Italy was lower when a norm of honest and direct expression was made salient to participants lower in soccer interest. These results establish schadenfreude as an emotion that is moderated by the salient dimensions of particular intergroup relations.     

Core affect and the psychological construction of emotion

At the heart of emotion, mood, and any other emotionally charged event are states experienced as simply feeling good or bad, energized or enervated. These states--called core affect--influence reflexes, perception, cognition, and behavior and are influenced by many causes internal and external, but people have no direct access to these causal connections. Core affect can therefore be experienced as free-floating (mood) or can be attributed to some cause (and thereby begin an emotional episode). These basic processes spawn a broad framework that includes perception of the core-affect-altering properties of stimuli, motives, empathy, emotional meta-experience, and affect versus emotion regulation; it accounts for prototypical emotional episodes, such as fear and anger, as core affect attributed to something plus various nonemotional processes.     

Sex, beauty, and the relative luminance of facial features

It has been suggested that the consistent luminance difference between the darker regions of the eyes and mouth and the lighter regions that surround them forms a pattern unique to faces. One of the more consistent uses of cosmetics to make the female face more attractive is to darken the eyes and mouth relative to the surrounding skin. The hypothesis that the size of the luminance difference between the eyes and mouth and the rest of the face affects the attractiveness of male and female faces differently was tested in four experiments in which attractiveness ratings were obtained for images of faces in which the luminance difference between the eyes and mouth and the rest of the face had been manipulated. Female faces were found to be more attractive when this luminance difference was increased than when it was decreased, and the opposite was found for male faces. An interpretation consistent with these results is that the luminance difference between the eyes and mouth and the rest of the face is naturally greater in women than men. In this case increasing or decreasing the luminance difference will make a face more feminine or masculine, respectively, and hence, more or less attractive depending on the sex of the face. Implications for the causes of cosmetics usage are discussed.     

Connectionist simulation of attitude learning: asymmetries in the acquisition of positive and negative evaluations

Connectionist computer simulation was employed to explore the notion that, if attitudes guide approach and avoidance behaviors, false negative beliefs are likely to remain uncorrected for longer than false positive beliefs. In Study 1, the authors trained a three-layer neural network to discriminate "good" and "bad" inputs distributed across a two-dimensional space. "Full feedback" training, whereby connection weights were modified to reduce error after every trial, resulted in perfect discrimination. "Contingent feedback," whereby connection weights were only updated following outputs representing approach behavior, led to several false negative errors (good inputs misclassified as bad). In Study 2, the network was redesigned to distinguish a system for learning evaluations from a mechanism for selecting actions. Biasing action selection toward approach eliminated the asymmetry between learning of good and bad inputs under contingent feedback. Implications for various attitudinal phenomena and biases in social cognition are discussed.     

Predicting the paths of peripherals: the interaction of identification and future possibilities

Two studies investigated how both degree of identification and the individual's position within the group influence aspects of group loyalty. The authors considered ingroup position in terms of both the individual's current position within a group and expectations concerning the likelihood that one's position might change in the future. Peripheral group members learned that their acceptance by other group members would improve in the future or that they could expect rejection by other group members. Various indices of group loyalty (ingroup homogeneity, motivation to work for the group, and evaluation of a motivated group member) showed that when group members anticipated future rejection, the lower the identification the less loyal they were. In contrast, those who expected future acceptance were more loyal (more motivated to work for the group) the lower their identification. Current group behavior depends on both intragroup future expectations and level of identification.
