Personality predicts temporal attention costs in the attentional blink paradigm

Accuracy for a second target is reduced when it is presented within 500 msec of a first target. This phenomenon is called the attentional blink (AB). A diffused attentional state (via positive affect or an additional task) has been shown to reduce the AB, whereas a focused attentional state (via negative affect) has been shown to increase the AB, purportedly by influencing the amount of attentional investment and flexibility. In the present study, individual differences in personality traits related to positive affect, negative affect, and cognitive flexibility were used to predict individual differences in AB magnitude. As hypothesized, greater extraversion and openness predicted smaller ABs. Greater openness also predicted higher overall target accuracy. Greater neuroticism predicted larger ABs and lower overall target accuracy. Conscientiousness, associated with less cognitive flexibility, predicted lower overall target accuracy. Personality may modulate the AB by influencing overinvestment via dispositional tendencies toward more or less stringent or capable cognitive control.     

Interaction of stimulus and contextual information during reading: Identifying words within sentences

In general, studies on the effects of a sentence context on word identification have focused on how context affects the efficiency of processing a single target word, presented separately from the context. Such studies probably would be incapable of measuring contextual facilitation resulting from cascaded or parallel processing of neighboring words within a sentence. To measure these and other types of facilitation, we presented entire phrases and sentences for subjects to read as fast as possible and to monitor for nonwords. Subjects read at rates representative of natural reading. Experiment 1 demonstrated a large contextual facilitation effect on decision time. Experiment 2 showed that facilitation is caused by specific semantic information and, perhaps to a greater degree, by nonpredictive syntactic information. Experiment 3 showed that the amount of facilitation is greater than could be accounted for by separate contributions from autonomous word level and sentence level processes. These results present difficulties for an autonomous model of reading, but are consistent with interactive models, in which the results of ongoing sentential analyses are combined with stimulus information to identify words.     

American and Chinese Students’ Calibration of Comprehension and Performance

In the present study we examined the ability of American and Chinese undergraduate students to calibrate their understanding of textbook passages translated into their native languages. Students read a series of texts and made predictions of their understanding of each text as well as the number of questions they would be able to answer correctly. Students also made postdictions of their test performance. Chinese students were significantly better than American students in calibrating their understanding of passages and predicting how many comprehension items they would answer correctly. Chinese students also outperformed American students on comprehension tests. All students were able to make more accurate postdictions of comprehension test scores than predictions. Results are related to possible instructional differences between American and Chinese students. Several possible directions for future research are discussed.     

Evidence for a Multi-Dimensional Latent Structural Model of Externalizing Disorders

Strong associations between conduct disorder (CD), antisocial personality disorder (ASPD) and substance use disorders (SUD) seem to reflect a general vulnerability to externalizing behaviors. Recent studies have characterized this vulnerability on a continuous scale, rather than as distinct categories, suggesting that the revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) take into account the underlying continuum of externalizing behaviors. However, most of this research has not included measures of disorders that appear in childhood [e.g., attention-deficit/hyperactivity disorder (ADHD) or oppositional defiant disorder (ODD)], nor has it considered the full range of possibilities for the latent structure of externalizing behaviors, particularly factor mixture models, which allow for a latent factor to have both continuous and categorical dimensions. Finally, the majority of prior studies have not tested multidimensional models. Using lifetime diagnoses of externalizing disorders from participants in the Fast Track Project (n?=?715), we analyzed a series of latent variable models ranging from fully continuous factor models to fully categorical mixture models. Continuous models provided the best fit to the observed data and also suggested that a two-factor model of externalizing behavior, defined as (1) ODD+ADHD+CD and (2) SUD with adult antisocial behavior sharing common variance with both factors, was necessary to explain the covariation in externalizing disorders. The two-factor model of externalizing behavior was then replicated using a nationally representative sample drawn from the National Comorbidity Survey-Replication data (n?=?5,692). These results have important implications for the conceptualization of externalizing disorders in DSM-5.     

Gavagai Is as Gavagai Does: Learning Nouns and Verbs From Cross‐Situational Statistics

Learning to map words onto their referents is difficult, because there are multiple possibilities for forming these mappings. Cross‐situational learning studies have shown that word‐object mappings can be learned across multiple situations, as can verbs when presented in a syntactic context. However, these previous studies have presented either nouns or verbs in ambiguous contexts and thus bypass much of the complexity of multiple grammatical categories in speech. We show that noun word learning in adults is robust when objects are moving, and that verbs can also be learned from similar scenes without additional syntactic information. Furthermore, we show that both nouns and verbs can be acquired simultaneously, thus resolving category‐level as well as individual word‐level ambiguity. However, nouns were learned more quickly than verbs, and we discuss this in light of previous studies investigating the noun advantage in word learning.     

Pilot Testing of an Online Training for Criminal Justice Professionals on Medication‐Assisted Treatment

There is widespread misunderstanding about medication‐assisted treatment (MAT) for opioid addiction. Although most MAT trainings target providers, criminal justice program staff and treatment referrers often determine offender placement. This article supports the efficacy of an online MAT training for criminal justice stakeholders.     

Impact of Peer Partner Support on Self Efficacy for Justice-Involved Parents: A Controlled Study of Juvenile Justice 101

Systems of care and other health-related initiatives have encouraged the proliferation of parent support policies in mental health, child welfare and education systems. However, the juvenile court system has relatively few programs that provide direct peer support for parents and little is known about the impact of parent support on families navigating the court process. Juvenile Justice 101 is one of only a few such programs. The present study examined the effect of the peer support element of Juvenile Justice 101 compared to video-only and no intervention conditions in a pre/post-test design. One hundred and ten parents agreed to participate in the study, 54 on a day with the peer support condition, 28 on a video-only day and 28 on a no-intervention day. Sixteen parents in the peer support condition were able to participate in the full program and seven parents in the video-only condition participated in the full video. Analyses disaggregate the effects of condition assignment and participation. Self-efficacy in navigating the juvenile court process improved for parents who participated in peer support but no improvement was observed for the other conditions. Parents in the peer support condition also rated peer partners higher than court staff on a dimension assessing process of care. The implications for practice and policy for peer support and family-driven services in juvenile court are discussed.
