Cognitive Tests,Constructs, and Content Validity: A commentary on Schmidt ()

This commentary discusses a number of issues that build on Schmidt's (International Journal of Selection and Assessment, 20, 1‐13 (2012)) perspective on content validity and cognitive tests. First, it elaborates on the relationship between the treatment of content validity in various professional standards and government guidelines. Second, it offers a differing perspective on the definition of ‘construct’ than that taken by Schmidt. Third, it elaborates on the settings in which content validity can and cannot be used to support the use of a given test in the cognitive ability domain.     

Personality, interpersonal circumplex, and DSM-5: A commentary on five studies

Much of personality is interpersonal, and what is interpersonal can be elegantly organized through the crossing of 2 fundamental dimensions of personality: agency and communion. The interpersonal circumplex has enriched substantially what is known about personality and in particular personality disorder, emphasizing to clinicians the importance of considering maladaptive interpersonal functioning when conducting clinical assessments. The purpose of this article is to provide a commentary on 5 articles concerning the interpersonal perspective on personality assessment. The contributions of these 5 studies are also understood relative to the proposed revisions to the American Psychiatric Association's personality disorder nomenclature, as the proposed revisions will be cutting out half of the interpersonal circumplex from further recognition.     

Measuring, estimating, and understanding the psychometric function: A commentary

The psychometric function, relating the subject’s response to the physical stimulus, is fundamental to psychophysics. This paper examines various psychometric function topics, many inspired by this special symposium issue ofPerception & Psychophysics: What are the relative merits of objective yes/no versus forced choice tasks (including threshold variance)? What are the relative merits of adaptive versus constant stimuli methods? What are the relative merits of likelihood versus up-down staircase adaptive methods? Is 2AFC free of substantial bias? Is there no efficient adaptive method for objective yes/no tasks? Should adaptive methods aim for 90% correct? Can adding more responses to forced choice and objective yes/no tasks reduce the threshold variance? What is the best way to deal with lapses? How is the Weibull function intimately related to thed’ function? What causes bias in the likelihood goodness-of-fit? What causes bias in slope estimates from adaptive methods? How good are nonparametric methods for estimating psychometric function parameters? Of what value is the psychometric function slope? How are various psychometric functions related to each other? The resolution of many of these issues is surprising.     

Temperament and intuition: A commentary on Feltz and Cokely

In this paper, we examine Adam Feltz and Edward Cokely’s recent claim that “the personality trait extraversion predicts people’s intuitions about the relationship of determinism to free will and moral responsibility” (INSERT REFERENCE). We will first present some criticisms of their work before briefly examining the results of a recent study of our own. We argue that while Feltz and Cokely have their finger on the pulse of an interesting and important issue, they have not established a robust and stable connection between extraversion and compatibilist-friendly intuitions.     

Recognition models evaluated: A commentary on Keren and Baggen

In a recent paper (1981), Keren and Baggen proposed two new models for alphanumeric confusion data, based on Tversky’s (1977) feature model of similarity, and compared them with Luce’s (1963) biased choice model. On the basis of their data, they concluded that, although the choice model fit slightly better, their models were to be preferred on grounds of parsimony and interpretability. It is shown here that both of these models are special cases of the Luce model, so that the general Luce model will necessarily fit better. This leads to considerable reinterpretation of Keren and Baggen’s conclusions. Finally, better methods of estimating parameters and evaluating goodness-of-fit are suggested, taking advantage of this relation between the models.     

Saying and doing: A commentary on a contingency-space analysis

This article addresses the contingency-space analysis (Matthews, Shimoff, & Catania, 1987) of the verbal regulation of behavior. From an applied perspective, the conceptualization of the relationship between saying and doing Matthews et al. present may be more complex than is necessary. The central issue in correspondence investigations is a simple one: does correspondence between what people say and what they do occur? The focus of this paper is on the applied and clinical importance of the relationship between verbalizations and relevant behavior and the implications for future research.     

Visual perspective and genetics: A commentary on Lemogne and colleagues

Lemogne and colleagues offer an interesting extension to their previous work on visual perspective and depression: Individuals at-risk for depression (defined as higher scores on Harm Avoidance), without a history of mood disorders, report retrieval of positive memories from the 3rd person perspective. Their findings suggest that the retrieval of positive experiences from the 3rd person perspective may be a risk-factor for depression, not just a lingering consequence of it. Their study, however, also reports a genetic association in a severely underpowered sample. Rather than focusing on gene x environment interactions, which large, well-powered studies on related phenotypes have failed to detect, a greater understanding of the phenomenology of visual perspective may be a more fruitful avenue for future research.     

On genes,environments and human development: A commentary to Goossens

Using the example of adolescent loneliness, Goossens (this issue) presented an outline of integral research programmes in European developmental psychology. Integral research programmes should combine longitudinal analysis with state-of-the-art methods from the neurosciences and use the gene×environment approach to track differential susceptibility to the environment. In my commentary, I suggest using control variables in gene–environment studies to rule out spurious associations, to make the studies more developmentally sensitive, and to stress the need for replication of gene–environment findings. I offer two hypothetical models for developmentally sensitive gene–environment studies on adolescent loneliness, namely a social cognition model and a social rejection model.
