Assessment of ADHD symptoms: comment on Gomez et al. (2003)

R. Gomez, G. L. Burns, J. A. Walsh, and M. A. de Moura (2003) examined the degree to which parent and teacher ratings of attention-deficit/hyperactivity disorder (ADHD) symptoms are accounted for by trait, source, and error variance. The importance and limitations of Gomez et al.'s findings are discussed in the context of clinical and research assessments of children suspected of having ADHD. Gomez et al.'s findings make clear that multimethod and multisource assessment protocols should be used in diagnosing children with this disorder. Further, clinicians and researchers must avoid relying too heavily on 1 source of data when evaluating the severity and frequency of ADHD symptoms.     

Evolving science in adolescence: comment on Ellis et al. (2012)

Ellis et al. (2012) bring an evolutionary perspective to bear on adolescent risky behavioral development, clinical practice, and public policy. The authors offer important insights that (a) some risky behaviors may be adaptive for the individual and the species by being hard-wired due to fitness benefits and (b) interventions might be more successful if they move with, rather than against, the natural tendencies of an adolescent. Ellis and colleagues criticize the field of developmental psychopathology, but we see the 2 fields as complementary. Their position would be enhanced by integrating it with contemporary perspectives on dynamic cascades through which normative behavior turns into genuinely maladaptive outcomes, dual processes in adolescent neural development, and adolescent decision making. Finally, they rightly note that innovation is needed in interventions and policies toward adolescent problem behavior.     

The validity of dietary restraint scales: comment on Stice et al. (2004)

In 4 empirical studies, E. Stice, M. Fisher, and M. R. Lowe calculated the correlations between some widely used dietary restraint scales and food intake. Failing to find substantial negative correlations, they concluded that these scales were invalid. The current article challenges this conclusion. For one thing, there is some evidence that restrained eaters do eat less than do unrestrained eaters under controlled experimental conditions favoring self-control. Dietary restraint is also associated with tendencies toward disinhibition under conditions favoring loss of self-control; such disinhibition often masks (but does not invalidate) the construct of dietary restraint. For these and other reasons, the assessment of food intake at a single eating episode may not capture overall dietary restriction. Finally, how much one eats does not necessarily indicate whether one has eaten less than one desired to eat. The authors suggest that the existing restraint scales do in fact validly assess restriction of food intake, albeit in a more complex fashion than is evident from simple correlations in single episodes.     

Evaluating the MSCEIT V2.0 via CFA: comment on Mayer et al. (2003)

This investigation uncovered several substantial errors in the confirmatory factor analysis results reported by J. D. Mayer, P. Salovey, D. R. Caruso, and G. Sitarenios (see record 2003-02341-015). Specifically, the values associated with the close-fit indices (normed fit index, Tucker-Lewis Index, and root-mean-square error of approximation) are inaccurate. A reanalysis of the Mayer et al. subscale intercorrelation matrix provided accurate values of the close-fit indices, which resulted in different evaluations of the models tested by J. D. Mayer et al. Contrary to J. D. Mayer et al., the 1-factor model and the 2-factor model did not provide good fit. Although the 4-factor model was still considered good fitting, the non-constrained 4-factor model yielded a non-positive definite matrix, which was interpreted to be due to the fact that two of the branch-level factors (Perceiving and Facilitating) were collinear, suggesting that a model with 4 factors was implausible.     

Evidence for covert attention switching from eye-movements. Reply to commentaries on Liechty et al., 2003

We argue that our research objectives in Liechty, Pieters, and Wedel (2003) are to provide generalizable insights into covert visual attention to complex, multimodal stimuli in their natural context, through inverse inference from eye-movement data. We discuss the most important issues raised by Feng (2003) and Reichle and Nelson (2003), in particular the task definition, inclusion of ad features, object-based versus space-based attention and the evidence for the where and what streams.Author names are in reverse alphabetical order.     

Adaptive calibration of children's physiological responses to family stress: the utility of evolutionary developmental theory: comment on Del Giudice et al. (2012) and Sturge-Apple et al. (2012)

Children's physiological reactions to stress are presented from the broader theoretical perspective of adaptive calibration to the environment, as rooted in life history theory. Del Giudice, Hinnant, Ellis, and El-Sheikh (2012) focus on children's physiological responses to a stressful task as a consequence of their history of family stress. Sturge-Apple, Davies, Martin, Cicchetti, and Hentges (2012) focus on the ways that children respond to a novel laboratory manipulation as a combined function of their temperament patterns and the harshness of their parental environment. The theoretical perspective employed provides an overarching framework that not only accounts for the findings presented here but also has heuristic value for future research on responses to early environmental risk. Future work in this area will benefit by inclusion of additional sympathetic nervous system (SNS) markers and neurotransmitters, inclusion of the role of gene expression in adaptive calibration, broader consideration of protective factors in the child's environment, and longitudinal work demonstrating the effects of adaptive calibration on children's future life history strategies and outcomes.     

An evaluation of a computational model of lexical access: comment on Dell et al. (1997)

The computational model of lexical access proposed by G. S. Dell, M. F. Schwartz, N. Martin, E. M. Saffran, and D. A. Gagnon (1997) is evaluated. They argued that fits of their model to naming data obtained from normal and brain-damaged patients support assumptions regarding interactivity in the lexicon, global damage in aphasia, and continuity between normal and aphasic naming behavior. Additional analysis reveals that the model fits the empirical data poorly and that the claims Dell et al. made on the basis of the model's performance would not follow even if the model were accurate. Although use of a novel automatic regression procedure improved the model's fit, it cannot account for 5 of Dell et al.'s 21 patients (24%), and its limitations were found to be inherent in its design. It is argued that claims such as those made by Dell et al. can only be addressed by considering evidence from multiple related tasks and by comparing multiple computational models.     

Handedness and drawing: attempting to complete the picture: a comment on Bruckner, et al. (2011)

In a recent study, Bruckner, Kastner-Koller, Deimann, and Voracek (2011) investigated the relationship between hand preference and drawing during preschool years. The present study offers interpretations in a larger framework which could contribute to the better understanding of that relationship, and provides future directions in this area.     

Intrahemispherical activation,visuomotor transmission,and the Simon effect: comment on Wascher et al. (2001)

On the basis of 3 experiments E. Wascher, U. Schatz, T. Kuder, and R. Verleger (2001) concluded, "The variety of tasks subsumed under the term Simon effect turned out to be heterogeneous" (p. 749). This comment critically evaluates the validity of their conclusion by considering their hypotheses methodology, specific conclusions, and proposed broader implications. Although the Simon effect is a behavioral phenomenon, E. Wascher et al. relied heavily on physiology in hypothesis generation, methodology, and interpretation of results. Moreover, methodological differences from most previous studies, combined with limited statistical support, nonreplication of previously reported behavioral phenomena inconsistencies in results across experiments, and evidence against a contribution of intrahemispherical activation by visuomotor pathways, strongly suggest that their conclusion should be viewed with caution.     

Reclaiming the individual from Hofstede's ecological analysis--a 20-year odyssey: comment on Oyserman et al. (2002)

D. Oyserman, H. M. Coon, and M. Kemmelmeier (2002) challenge the stereotype that European Americans are more individualistic and less collectivistic than persons from most other ethnic groups. The author contends that this stereotype took firm empirical root with G. Hofstede's (1980) monumental publication identifying the United States as the most individualistic of his then 40 nations. This empirical designation arose because of challengeable decisions Hofstede made about the analysis of his data and the labeling of his dimensions. The conflation of concepts under the rubric of cultural individualism plus psychologists' unwarranted psychologizing of the construct then combined with Hofstede's empirical location of America to set a 20-year agenda for data collection. Oyserman et al. disentangle and organize this mass of studies, enabling the discipline of cross-cultural psychology to forge ahead in more productive directions, less reliant on previous assumptions and measures.     

Depression, autonomic function, and cardiorespiratory fitness: comment on Hughes, et al. (2010)

A recent paper by Hughes and colleagues suggested that dysfunction of the autonomic nervous system in depressed cardiac patients was partly explained by reduced physical activity and fitness. Other data demonstrate that exercise training and improvements in fitness not only lead to improvements in autonomic function in coronary patients but also reduce depression and depression-related increased mortality.
