Stability and Invariance of Psychopathic Traits from Late Adolescence to Young Adulthood

The current study examined the longitudinal stability and invariance of psychopathic traits in a large community sample of male twins from ages 17 to 23. Participants were assessed across 6 years to gauge the stability and measurement invariance of the Minnesota Temperament Inventory (MTI), a Cleckley-based measure of psychopathic personality traits, and how family functioning and externalizing behavior were linked to these traits. A latent variable approach was used to model the structure of the MTI and provide a statistical test of measurement invariance across time. The results revealed support for invariance and moderate to strong stability of the MTI factors, which showed significant associations with the external correlates in late adolescence but not early adulthood.     

Reappraising the situation and its impact on aggressive behavior

Much work has focused on how reappraisal is related to emotions, but not behaviors. Two experiments advanced aggression theory by (a) testing how cognitive and attributional forms of reappraisal are related to aggressive affect and behavior, (b) testing variables that theoretically mediate the relation between attributional reappraisal and aggressive behavior, (c) testing the moderating influences of cognitive and attributional reappraisal on aggressive behavior, and (d) developing and testing an intervention aimed at reducing vengeance through reappraisal training. Study 1 used an essay writing task in a 3 (feedback: provocation, no feedback, praise) × 2 (mitigating information: present, absent) experimental design. Provoked participants who did not receive mitigating information were significantly more aggressive than provoked participants who received mitigating information. State vengeance was a significant mediator. Study 2 examined an experimental intervention on vengeance over a 16-week semester. Intervention participants who had the largest increase in reappraisal displayed the greatest decrease in vengeance. Overall, these findings suggest that reappraisal reduces vengeance and aggressive behavior.     

Convergent, but not divergent, thinking predicts susceptibility to associative memory illusions

The relationship between creativity and susceptibility to associative memory illusions in the Deese/Roediger-McDermott procedure was investigated using a multiple regression analysis. Susceptibility to false recognition was significantly predicted by performance on a measure of convergent thinking (the Remote Associates Task) but not by performance on a measure of divergent thinking (the Alternative Uses Task). These findings suggest that the ability to engage in convergent (but not divergent) thinking underlies some of the individual variation in susceptibility to associative memory illusions by influencing the automaticity with which critical lures are activated at encoding.     

Motor execution affects action prediction

Previous studies provided evidence of the claim that the prediction of occluded action involves real-time simulation. We report two experiments that aimed to study how real-time simulation is affected by simultaneous action execution under conditions of full, partial or no overlap between observed and executed actions. This overlap was analysed by comparing the body sides and the movement kinematics involved in the observed and the executed action. While performing actions, participants observed point-light (PL) actions that were interrupted by an occluder, followed by a test pose. The task was to judge whether the test pose depicted a continuation of the occluded action in the same depth angle. Using a paradigm proposed by Graf et al., we independently manipulated the duration of the occluder and the temporal advance of the test pose relative to occlusion onset (occluder time and pose time, respectively). This paradigm allows the assessment of real-time simulation, based on prediction performance across different occluder time/pose time combinations (i.e., improved task performance with decreasing time distance between occluder time and pose time is taken to reflect real-time simulation). The PL actor could be perceived as from the front or back, as indicated by task instructions. In Experiment 1 (front view instructions), evidence of action simulation was obtained for partial overlap (i.e., observed and performed action corresponded either in body side or movement kinematics), but not for full or no overlap conditions. The same pattern was obtained in Experiment 2 (back view instructions), ruling out a spatial compatibility explanation for the real-time pattern observed. Our results suggest that motor processes affect action prediction and real-time simulation. The strength of their impact varies as a function of the overlap between observed and executed actions.     

Does a sensory processing deficit explain counting accuracy on rapid visual sequencing tasks in adults with and without dyslexia?

The experiments conducted aimed to investigate whether reduced accuracy when counting stimuli presented in rapid temporal sequence in adults with dyslexia could be explained by a sensory processing deficit, a general slowing in processing speed or difficulties shifting attention between stimuli. To achieve these aims, the influence of the inter-stimulus interval (ISI), stimulus duration, and sequence length were evaluated in two experiments. In the first that used skilled readers only, significantly more errors were found with presentation of long sequences when the ISI or stimulus durations were short. Experiment 2 used a wider range of ISIs and stimulus durations. Compared to skilled readers, a group with dyslexia had reduced accuracy on two-stimulus sequences when the ISI was short, but not when the ISI was long. Although reduced accuracy was found on all short and long sequences by the group with dyslexia, when performance on two-stimulus sequences was used as an index of sensory processing efficiency and controlled, group differences were found with presentation of stimuli of short duration only. We concluded that continuous, repetitive stimulation to the same visual area can produce a capacity limitation on rapid counting tasks in all readers when the ISIs or stimulus durations are short. While reduced accuracy on rapid sequential counting tasks can be explained by a sensory processing deficit when the stimulus duration is long, slower processing speed in the group with dyslexia explains the greater inaccuracy found as sequence length is increased when the stimulus duration is short.     

Mothers’ and Adolescents’ Perceptions of Family Environment and Adolescent Social-Emotional Functioning

Research has emphasized the importance of the relationship between family functioning and adolescent behavioral development. The present study examines family environment and social-emotional functioning of primarily minority adolescents, viewed from both adolescents’ and mothers’ perspectives. Participants were a school-based sample of adolescents with and without risk for emotional and behavioral disabilities and their mothers (N = 86 dyads). Results suggested an association between the mothers’ views of their adolescent children’s problem behaviors and the adolescents’ self-ratings of risk-taking behaviors across 5 years. Overall, mothers of the at risk youth receiving special education services reported higher ratings of youth problem behaviors, but results also indicated that mothers of the at risk adolescent boys not receiving special education services perceived greater depressive symptoms in their children and more family conflict in their homes. Mothers of youth at risk but not receiving special education services experienced higher levels of stress associated with being a parent than mothers of the not-at-risk adolescents. The parent measures of adolescent behavior and depressive symptoms, family conflict, and parental stress were not predictive of the social-emotional functioning of these adolescents in the multilevel models. Implications of these findings for early identification and family focused intervention programs are discussed.     

Succeeding in Rural Mental Health Practice: Being Sensitive to Culture by Fitting in and Collaborating

Sustainable solutions to the access to mental health care problems are complex and must address both the availability of mental health care resources and the acceptability of those resources to consumers. The purpose of this study was to determine how to address the acceptability problem by learning from medical and mental health care providers what mental health therapists need to know to be successful in providing care in rural communities. Using a qualitative design, focus groups were conducted in three rural communities (<2,500) with medical and mental health care providers practicing in these communities. Data were analyzed using inductive qualitative methods. Results indicate that in addition to sound clinical skill, mental health therapists should (A) be sensitive to the culture of the rural community in which they are working and (B) practice in a way that accommodates to the care culture of the community. The latter includes spending time with patients commensurate with what is expected by other providers, engaging in generalist practice, and collaborating with local providers in patient care. An important implication of these results is that mental health care must be acceptable to both the residents of the community and the gatekeepers to health care.     

Hide and seek: The theory of mind of visual concealment and search

Researchers have investigated visual search behavior for almost a century. During that time, few studies have examined the cognitive processes involved in hiding items rather than finding them. To investigate this, we developed a paradigm that allowed participants to indicate where they would hide (or find) an item that was to be found (or hidden) by a friend or a foe. We found that (i) for friends more than foes, participants selected the pop-out item in the display, and (ii) when the display was homogeneous, they selected nearby and corner items. These behaviors held for both hiding and finding, although hide and find behaviors were not identical. For pop-out displays, decision times were unusually long when hiding an item from a foe. These data converge on the conclusion that the principles of search and concealment are similar, but not the same. They also suggest that this paradigm will provide researchers a powerful method for investigating theory of mind in adults.     

An Evaluation of the Word Triad Method for Monitoring Spelling Progress

Although spelling skill progress has typically been studied within the context of students' responses to written story starters (Deno, Marsten, & Mirkin, 1982; Fuchs & Fuchs, 2011; Hosp, Hosp, & Howell, 2007; Shinn & Shinn, 2002), there has been little research conducted within a curriculum-based measurement framework that has studied spelling progress monitoring on a weekly basis throughout an entire school year. The authors evaluated spelling progress using word triads, defined as a group of 3 words (with the same number of letters) that have a similar phonetic or morphological structure. Successful spelling of word triads as the unit of analysis has the potential to be more useful diagnostically to teachers than successful spelling of single words as the unit of analysis. An alternating series of three 15-word spelling tests were administered weekly to 10 third- and fourth-grade classrooms in the same school district throughout the school year for 8 rounds (1 round = 3 weeks of different but phonetically and/or morphologically similar word lists). Results indicate steady progress throughout the school year in the correct spelling of word triads (despite teacher reporting of no explicit spelling instruction in classrooms using in the words employed in the study). Correlations between the number of correctly spelled word triads with standard scores from a group-administered communication arts test were significant and comparable to alternate spelling test scoring methods. The authors conclude with limitations of the study and implications for practitioners.
