Short theta burst stimulation to left frontal cortex prior to encoding enhances subsequent recognition memory

Deep semantic encoding of verbal stimuli can aid in later successful retrieval of those stimuli from long-term episodic memory. Evidence from numerous neuropsychological and neuroimaging experiments demonstrate regions in left prefrontal cortex, including left dorsolateral prefrontal cortex (DLPFC), are important for processes related to encoding. Here, we investigated the relationship between left DLPFC activity during encoding and successful subsequent memory with transcranial magnetic stimulation (TMS). In a pair of experiments using a 2-session within-subjects design, we stimulated either left DLPFC or a control region (Vertex) with a single 2-s train of short theta burst stimulation (sTBS) during a semantic encoding task and then gave participants a recognition memory test. We found that subsequent memory was enhanced on the day left DLPFC was stimulated, relative to the day Vertex was stimulated, and that DLPFC stimulation also increased participants’ confidence in their decisions during the recognition task. We also explored the time course of how long the effects of sTBS persisted. Our data suggest 2 s of sTBS to left DLPFC is capable of enhancing subsequent memory for items encoded up to 15 s following stimulation. Collectively, these data demonstrate sTBS is capable of enhancing long-term memory and provide evidence that TBS protocols are a potentially powerful tool for modulating cognitive function.

A Brief,Hospital-Initiated Motivational Interviewing and Acceptance and Commitment Therapy Intervention to Link Postpartum Mothers Who Use Illicit Drugs With Treatment and Reproductive Care: A Case Report

Maternal substance use during the prenatal period often results in infants with compromised health outcomes. The American College of Obstetrics and Gynecology recommends screening, brief motivational interviewing, and referral to existing treatment for women who use illicit substances prenatally. However, many of these women do not present for prenatal care and are not identified as using substances until delivery of their infants, many of whom are admitted to the neonatal intensive care unit (ICU). We describe a case from a novel, hospital-initiated intervention study, Moms in ACTion (MIACT) that combines motivational interviewing (MI) and acceptance and commitment therapy (ACT) to target new mothers with an infant in the neonatal ICU who screen positive for illicit substance use prenatally or at delivery. The MIACT program consists of an adaptive intervention that includes up to three sessions. Initiation of substance use treatment and reproductive care via a gynecological visit are the primary targets of the intervention. Urine samples were collected at 2- and 6-month follow-up visits. The participant successfully completed the program, achieved both treatment outcomes, and had negative urine drug screens at follow-up visits. Improvements in readiness to change and psychological flexibility were also observed. The present case report of a new mother who used substances demonstrated feasibility for combining MI and ACT treatments and the potential for MIACT to increase treatment and contraception initiation, ultimately preventing future substance-exposed pregnancies.

A FURTHER EVALUATION OF PICTURE PROMPTS DURING AUDITORY‐VISUAL CONDITIONAL DISCRIMINATION TRAINING

This study was a systematic replication and extension of Fisher, Kodak, and Moore (2007 ), in which a picture prompt embedded into a least‐to‐most prompting sequence facilitated acquisition of auditory‐visual conditional discriminations. Participants were 4 children who had been diagnosed with autism; 2 had limited prior receptive skills, and 2 had more advanced receptive skills. We used a balanced design to compare the effects of picture prompts, pointing prompts, and either trial‐and‐error learning or a no‐reinforcement condition. In addition, we assessed the emergence of vocal tacts for the 2 participants who had prior tact repertoires. Picture prompts enhanced acquisition for all participants, but there were no differential effects on tact emergence. The results support a generality of the effect reported by Fisher et al. and suggest that a variety of learners may benefit from the incorporation of picture prompts into auditory‐visual conditional discrimination training.     

Construal level mind-sets moderate self- and social stereotyping

Construal level theory suggests that events and objects can be represented at either a higher, more abstract level involving consideration of superordinate goals, desirability, global processing, and broad categorizations or a lower, more concrete level involving consideration of subordinate goals, feasibility, local processing, and narrow categorizations. Analogously, social targets (including the self) can be represented more broadly, as members of a group, or more narrowly, as individuals. Because abstract construals induce a similarity focus, they were predicted to increase the perceived fit between social targets and a salient social category. Accordingly, placing individuals into a more abstract construal mind-set via an unrelated task increased the activation and use of stereotypes of salient social groups, stereotype-consistent trait ratings of the self, group identification, and stereotype-consistent performance relative to more concrete construal mind-sets. Thus, nonsocial contextual influences (construal level mind-sets) affect stereotyping of self and others.     

Integrating Social Identity and the Theory of Planned Behavior: Predicting Withdrawal from an Organizational Recruitment Process

This study develops and tests a model of applicant withdrawal. Drawing on tenets from social identity theory and the theory of planned behavior, this study proposes that applicants who highly identify with an organization will experience higher pursuit intentions and subsequently be less inclined to withdraw from recruitment. Data were collected from a sample of 669 applicants to the U.S. military at 2 intervals, separated by 3 months. Strong support was found for the proposed theoretical model. Implications for research and practice will be discussed.     

Modal Mereology and Modal Supervenience

David Lewis insists that restrictivist composition must be motivated by and occur due to some intuitive desiderata for a relation R among parts that compose wholes, and insists that a restrictivist??s relation R must be vague. Peter van Inwagen agrees. In this paper, I argue that restrictivists need not use such examples of relation R as a criterion for composition, and any restrictivist should reject a number of related mereological theses. This paper critiques Lewis and van Inwagen (and others) on their respective mereological metaphysics, and offers a Golden Mean between their two opposite extremes. I argue for a novel account of mereology I call Modal Mereology that is an alternative to Classical Mereology. A modal mereologist can be a universalist about the possible composition of wholes from parts and a restrictivist about the actual composition of wholes from parts. I argue that puzzles facing Modal Mereology (e.g., puzzles concerning Cambridge changes and the Problem of the Many, and how to demarcate the actual from the possible) are also faced in similar forms by classical universalists. On my account, restricted composition is rather motivated by and occurs due to a possible whole??s instantiating an actual type. Universalists commonly believe in such types and defend their existence from objections and puzzles. The Modal Mereological restrictivist can similarly defend the existence of such types (adding that such types are the only wholes) from similar objections and puzzles.
