To evaluate the relationships among performance validity, symptom validity, symptom self-report, and objective cognitive testing.
Combat Veterans (
= 338) completed a neurocognitive assessment battery and several self-report symptom measures assessing depression, posttraumatic stress disorder (PTSD) symptoms, sleep quality, pain interference, and neurobehavioral complaints. All participants also completed two performance validity tests (PVTs) and one stand-alone symptom validity test (SVT) along with two embedded SVTs.
Results of an exploratory factor analysis revealed a three-factor solution performance validity, cognitive performance, and symptom report (SVTs loaded on the third factor). Results of t tests demonstrated that participants who failed PVTs displayed significantly more severe symptoms and significantly worse performance on most measures of neurocognitive functioning compared to those who passed. Participants who failed a stand-alone SVT also reported significantly more severe symptomatold to cognitive performance and symptom report based on the utilized cutoff score.

To function in the guidance of real-world search, however, such learning must be contingent on the context in which the search occurs and the object that is the target of search. The former has been studied extensively under the rubric of contextual cuing. Here, we examined, for the first time, categorical cuing The role of object categories in structuring the acquisition of statistical regularities used to guide visual search. After an exposure session in which participants viewed six exemplars with the same general color in each of 40 different real-world categories, they completed a categorical search task, in which they searched for any member of a category based on a label cue. Targets that matched recent within-category regularities were found faster than targets that did not (Experiment 1). Such categorical cuing was also found to span multiple recent colors within a category (Experiment 2). It was observed to influence both the guidance of search to the target object (Experiment 3) and the basic operation of assigning single exemplars to categories (Experiment 4). Finally, the rapid acquisition of category-specific regularities was also quickly modified, with the benefit rapidly decreasing during the search session as participants were exposed equally to the two possible colors in each category. The results demonstrate that object categories organize the acquisition of perceptual regularities and that this learning exerts strong control over the instantiation of the category representation as a template for visual search.

In this article we investigate the role of representative design in achieving valid and reliable psychological assessments, by focusing on a widely used behavioral measure of risk taking-the Balloon Analogue Risk Task (BART). Specifically, we demonstrate that the typical implementation of this task violates the principle of representative design, thus conflicting with the expectations people likely form from real balloons. IPI-145 ic50 This observation may provide an explanation for the previously observed limitations in some of the BART’s psychometric properties (e.g., convergent validity with other measures of risk taking). To experimentally test the effects of improved representative designs, we conducted two extensive empirical studies (N = 772 and N = 632), finding that participants acquired more accurate beliefs about the optimal behavior in the BART because of these task adaptions. Yet, improving the task’s representativeness proved to be insufficient to enhance the BART’s psychometric properties. It follows that for the development of valid behavioral measurement instruments-as are needed, for instance, in functional neuroimaging studies-our field has to overcome the philosophy of the “repair program” (i.e., fixing existing tasks). Instead, we suggest that the development of valid task designs requires novel ecological assessments, aimed at identifying those real-life behaviors and associated psychological processes that lab tasks are supposed to capture and generalize to.

In this paper, we introduce a novel experimental paradigm to study the differences between memory processes at play in standard list recall versus in preferential choice. Using computational memory models, fit to data from 2 preregistered experiments, we find that some established memory regularities (primacy, recency, semantic clustering) emerge in preferential choice, whereas others (temporal clustering) are significantly weakened relative to standard list recall. Notably, decision-relevant features, such as item desirability, play a stronger role in guiding retrieval in choice. Our results suggest memory processes differ across preferential choice and standard memory tasks, and that choice modulates memory by differentially activating decision-relevant features such as what we like.

Psychopathy is a serious personality disorder reputed for resistance to correctional and forensic mental health treatment and synonymous with being high risk for different recidivism outcomes; it is not readily associated with an abundance of positive qualities or protective factors. Research has yet to examine the presence of protective factors as a function of psychopathy in correctional samples and the risk-relevance of protective factors for high-psychopathy men.
The present study examined the association of psychopathy and protective factors to recidivism in a Canadian sample of 461 men who attended sexual-offense-specific treatment and followed up nearly 10-year postrelease. The Psychopathy Checklist-Revised (PCL-R; Hare,
1991; Hare,
2003) and the Structured Assessment of Protective Factors (SAPROF; de Vogel et al.,
, 2011, 10, 171) were rated from institutional files and recidivism data were obtained from official criminal records.
PCL-R scores were inversely related to SAPROF scores; however, even men scoring high on the PCL-R made significant pre-post changes on protective factors.
