Verbal memory abilities of children with brain tumors.

Several critical neuroanatomical structures and pathways for memory performance are located in the third ventricle region. This led us to predict that verbal memory abilities would be more impaired in children treated for third ventricle tumors compared to those treated for cerebellar tumors. Archival data was obtained from 24 pediatric patients with third ventricle region tumors and 18 pediatric patients with cerebellar tumors. Neuroradiological verifications of tumor involvement and hydrocephalus severity (i.e., Evans Index) on preoperative scans and MRIs proximal to the time of the neuropsychological evaluation were conducted. The potential confounds of hydrocephalus severity, seizure medication, age, radiation treatment, and chemotherapy were addressed. Verbal IQ was comparable between tumor groups and in the Average range. The third ventricle region group performed significantly worse on list learning and delayed list recall compared to the cerebellar group. Their mean performance was in the clinically impaired range on both trials. The third ventricle region tumor group performed better than the cerebellar tumor group on Digit Span, a basic repetition, attention span task. These findings support the hypothesis that pediatric patients with third ventricle region brain tumors are more likely to be impaired on verbal recall tasks compared to pediatric patients with cerebellar brain tumors. In contrast, patients who were treated for cerebellar tumors were more impaired on the basic repetition, attention span task compared to patients who were treated for third ventricle tumors. Future studies should examine the specific neuroanatomical structures and pathways that are damaged and may influence differential cognitive impairments in children.     

Who Will Volunteer? Religiosity, Everyday Racism, and Social Participation Among African American Men

This study explores the relative importance of everyday racism, empathic concern, communalism, and religiosity as predictors of pro-social involvement (i.e., volunteerism and membership in political/social justice organizations) among a sample of African American men (N = 151). Church involvement emerged as a positive predictor of the likelihood that these men were involved in volunteer work as well as the number of hours that men dedicated to volunteer work. Communalism positively predicted the amount of time (in hours per year) that men were involved in volunteer work. Subjective religiosity and the stress of everyday racism were associated with a greater likelihood of being a member of a political–social justice organization. Implications of these findings are discussed.     

National Registry of Psychotherapies

In the United States, there is a National Registry of Evidence-Based Programs and Practices (NREPP), which is a listing of treatments and interventions in psychotherapy. In 2012, NREPP invited our research team to submit an application for registration of our short-term interpretive group therapy for patients experiencing complicated grief, which we had used since 1986. From the beginning, we experienced difficulties that seemed to be largely attributable to a lack of professional skills required of the director. The director and her team used the metaphor of American football to describe parts of application process. Despite continuing difficulties, we finally completed the application process on time. Eventually, the reviews of the application were completed and the application was approved. The information we provide in this article mainly concerns the trials and tribulations associated with the application process. Overall, the process was frustrating and time-consuming. Consideration of additional variables, such as patient personality characteristics, would likely have provided a more useful set of findings.     

Internet‐based self‐tailored deposit contracts to promote smoking reduction and abstinence

Deposit contracting may reduce costs and increase efficacy in contingency management interventions. We evaluated two Internet‐based deposit contract arrangements for smoking. In Experiment 1, nine participants deposited self‐selected amounts that could be earned back for meeting goals. During treatment, participants were reimbursed for breath samples with less than or equal to 6 parts per million carbon monoxide and met the criterion for 47% of samples compared to 1% during baseline. In Experiment 2, 10 participants’ deposits were matched up to $50. No samples met the criterion during baseline but 41.5% met it during treatment. The average deposit was $82 in Experiment 1 and $49 in Experiment 2. Participants rated the intervention favorably and sample submission rates were high. These experiments suggest that Internet‐based self‐tailored deposits are acceptable, feasible, and can promote brief reduction and abstinence in some smokers. Future research should investigate individual and intervention factors that affect long‐term cessation and uptake of deposit contracts.     

Think manager—think male,think follower—think female: Gender bias in implicit followership theories

Because of the overlap between the social roles of women and followers, we predicted that people would show a bias, that is, favor female followers over male followers. To support this hypothesis, we conducted two studies: An explicit test of the bias using a scenario design and an implicit association test (IAT)‐based study. Both studies show that the role of an ideal follower is more strongly associated with the female gender role, which seems to be caused partly by a more communal connotation of the follower role. This effect might contribute to the underrepresentation of women in leadership positions as they are perceived to be an ideal fit for followership positions; but it may also push men away from being followers and into leadership positions.     

Thought-experiment intuitions and truth in fiction

What sorts of things are the intuitions generated via thought experiment? Timothy Williamson has responded to naturalistic skeptics by arguing that thought-experiment intuitions are judgments of ordinary counterfactuals. On this view, the intuition is naturalistically innocuous, but it has a contingent content and could be known at best a posteriori. We suggest an alternative to Williamson’s account, according to which we apprehend thought-experiment intuitions through our grasp on truth in fiction. On our view, intuitions like the Gettier intuition are necessarily true and knowable a priori. Our view, like Williamson’s, avoids naturalistic skepticism.     

They're digging up the road again: the processing cost of institutional they

It is commonplace to use the pronoun they to refer to agents in certain situations without ever providing a referent, as in On the train, they served really bad coffee. Such an example we call “Institutional They”, because such defaults typically represent the actions of some agent tied stereotypically to a situation. These cases represent an important subset of unheralded pronouns (Gerrig, 1986), pronouns without any explicit antecedent. While in many situations, the occurrence of referential pronouns without explicit antecedents entails a processing cost, an eye-tracking experiment revealed no reliable detectable costs associated with Institutional They. However, there were for singular pronouns without antecedents in the same situations. We argue that Institutional They cases result from properties of plural pronouns (they and them). These will accept underspecified type-referents, while singular pronouns require specified token-referents. Failure to identify token-referents results in disruption of processing in the case of singulars, but not in the case of the plurals.     

A preliminary evaluation of the emergence of novel mand forms

Strategies that produce generalized responding are valuable, especially with regard to language acquisition, because relatively little training may result in large behavior changes. Conditions that result in generalized manding were analyzed in the current study. We demonstrated in reversal designs that undesirable or single-word responses were the predominant mand forms of 3 preschool children. Multiple baseline designs with 2 participants and a reversal design with 1 participant were then used to demonstrate the extent to which differential reinforcement of single-word mands (e.g., "cars") or framed mands (e.g., "I want the cars, please") would result in the emergence of other single-word and framed mands for different items (e.g., mands for music, puppets, or puzzles). Results showed that prompting and differential reinforcement of one or two mand frames resulted in the emergence of other framed mands for all participants.     

Long-term memory for instrumental responses does not undergo protein synthesis-dependent reconsolidation upon retrieval

Recent evidence indicates that certain forms of memory, upon recall, may return to a labile state requiring the synthesis of new proteins in order to preserve or reconsolidate the original memory trace. While the initial consolidation of "instrumental memories" has been shown to require de novo protein synthesis in the nucleus accumbens, it is not known whether memories of this type undergo protein synthesis-dependent reconsolidation. Here we show that low doses of the protein synthesis inhibitor anisomycin (ANI; 5 or 20 mg/kg) administered systemically in rats immediately after recall of a lever-pressing task potently impaired performance on the following daily test sessions. We determined that the nature of this impairment was attributable to conditioned taste aversion (CTA) to the sugar reinforcer used in the task rather than to mnemonic or motoric impairments. However, by substituting a novel flavored reinforcer (chocolate pellets) prior to the administration of doses of ANI (150 or 210 mg/kg) previously shown to cause amnesia, a strong CTA to chocolate was induced sparing any aversion to sugar. Importantly, when sugar was reintroduced on the following session, we found that memory for the task was not significantly affected by ANI. Thus, these data suggest that memory for a well-learned instrumental response does not require protein synthesis-dependent reconsolidation as a means of long-term maintenance.     

Predictors of paternal involvement for resident and nonresident low-income fathers

In a sample of low-income families (N = 239), structural equation models assessed predictors of fathers' involvement with preschool-aged children in instrumental, behavioral, and emotional realms. Results suggest that parental conflict has a strong negative relation with father involvement. Fathers' human capital characteristics, healthy psychosocial functioning, and past stability in family relationships all predicted greater father involvement directly and/or indirectly through parental conflict. Numerous differences emerged in the predictive models between resident and nonresident fathers, although few differences were statistically significant. Results suggest that policy efforts aimed at enhancing fathers' responsible parenting should focus both on increasing fathers' human and social capital and on supporting positive family processes.
