Community Influences on Adjustment in First Grade: An Examination of an Integrated Process Model

We examined the impact of neighborhood characteristics both directly and indirectly as mediated by parent coaching and the parent/child affective relationship on behavioral and school adjustment in a sample of urban dwelling first graders. We used structural equations modeling to assess model fit and estimate direct, indirect, and total effects of neighborhood structural and social characteristics on parenting behavior and child outcomes. Observed physical incivilities in the neighborhood were associated with lower levels of parent eliciting behavior and higher levels of child behavior problems. The effects of neighborhood structural characteristics were mediated partially through neighborhood community involvement with children, which had a direct significant impact on parent eliciting behavior and an indirect effect on child behavior problems. Neighborhood community involvement with children was associated with higher levels of parent eliciting behavior and lower levels of child behavior problems. Observed physical incivilities had a significant indirect association with poor school adjustment and a marginally significant association with positive school adjustment to first grade. Neighborhood community involvement with children was more strongly associated with positive school adjustment than poor school adjustment.     

The influence of intertrial interval food on extinction and devaluation in chain schedules

The authors exposed pigeons to 2 equal 3-link chains by using variable-interval schedules of reinforcement. An intertrial interval (ITI) bisected by free food separated the chains. After baseline training, the authors presented terminal links in a successive discrimination to devalue 1 terminal link: The authors reinforced responses to 1 terminal link and extinguished responses to the other. The authors then presented full chains in extinction, except that they continued to deliver free food during the midpoint of the ITI. There were 2 principal findings. First, across all extinction conditions, responding decreased but did not extinguish. Second, when extinction testing revealed a terminal link devaluation effect in the 3rd condition, responding to the initial link was affected, but not middle-link responding. Overall, the results suggested that ITI food presentations can exert a substantial effect on responding in 3-link chain schedules, and they appear to influence both the pattern of extinction and devaluation effects.     

Group-Based Trust in Strangers: The Role of Stereotypes and Expectations

ABSTRACT— Across two studies, we provide evidence for group-based trust in strangers. Specifically, when we offered participants a choice between an unknown monetary allocation made by an in-group (university or major) or an out-group allocator, both of whom had total control over the distribution of an identical sum of money, participants strongly preferred the in-group allocator. This preference occurred regardless of whether the stereotype of the in-group was relatively more positive or more negative than that of the out-group. However, this preference did not persist when participants believed that the allocator was unaware of their group membership. Measures of expected share of the allocator's funds support our hypothesis that differential trust of in-group members results from expectations of altruistic and fair behavior toward fellow in-group members rather than from positive stereotypes of the in-group.     

Effects of exposure to community violence on school functioning: The mediating role of posttraumatic stress symptoms

This study investigated the association between exposure to community violence (ECV) and school functioning, as well as posttraumatic stress (PTS) symptoms as a potential mediator of the relationship. PTS symptoms are commonly associated with ECV, and are characterized by difficulty regulating emotions and behaviors. Thus, PTS symptomatology may be one mechanism through which community violence impacts school functioning. The community-based sample included 47 low-income African American children (aged 10-13). Results revealed that ECV was inversely related to academic performance and attendance. Symptoms of posttraumatic stress emerged as a mediator of the relation between ECV and academic performance. Results have implications for urban students who face violence in their communities, and emphasize the need for school-based mental health services.     

Shared intention and personal intentions

This article explores the question: what is it for two or more people to intend to do something in the future? In a technical phrase, what is it for people to share an intention? Extending and refining earlier work of the author’s, it argues for three criteria of adequacy for an account of shared intention (the disjunction, concurrence, and obligation criteria) and offers an account that satisfies them. According to this account, in technical terms explained in the paper, people share an intention when and only when they are jointly committed to intend as a body to do such-and-such in the future. This account is compared and contrasted with the common approach that treats shared intention as a matter of personal intentions, with particular reference to the work of Michael Bratman.     

Suppose Freud had chosen Orestes instead

Abstract :  The paper argues that the story of Oedipus, however understood, conveys psychic truth of no greater or more central importance to human development than do the stories of many other myths. A distinction is made between sophisticated theories developed out of Freud's original concept of the Oedipus complex, and the adherence by some clinicians to his original sexual theory. The meaning of Sophocles' play Oedipus the King is found to lie in the clash between Oedipus' omnipotent narcissism ( hubris) and the power of the unconscious psyche, rather than in cross-generational sex. Emphasis is placed on the clinical usefulness of understanding all myths symbolically. The Oresteia by Aeschylus is offered as a story about pre-Oedipal (in the Freudian sense) psychic states. This trilogy shows symbolically the developing of an ego, the establishment of moral judgement and the integration of our shadow (the Furies). It also shows the parallel development of structures of law in society to replace instinctive blood feuds. It is suggested that had Freud chosen Orestes instead of Oedipus, the course of both psychoanalysis and of Western society would have had a different emphasis.     

Overt naming fMRI pre- and post-TMS: Two nonfluent aphasia patients, with and without improved naming post-TMS

Two chronic, nonfluent aphasia patients participated in overt naming fMRI scans, pre- and post-a series of repetitive transcranial magnetic stimulation (rTMS) treatments as part of a TMS study to improve naming. Each patient received 10, 1-Hz rTMS treatments to suppress a part of R pars triangularis. P1 was a ‘good responder’ with improved naming and phrase length; P2 was a ‘poor responder’ without improved naming.Pre-TMS (10 years poststroke), P1 had significant activation in R and L sensorimotor cortex, R IFG, and in both L and R SMA during overt naming fMRI (28% pictures named). At 3 mo. post-TMS (42% named), P1 showed continued activation in R and L sensorimotor cortex, R IFG, and in R and L SMA. At 16 mo. post-TMS (58% named), he also showed significant activation in R and L sensorimotor cortex mouth and R IFG. He now showed a significant increase in activation in the L SMA compared to pre-TMS and at 3 mo. post-TMS (p < .02; p < .05, respectively). At 16 mo. there was also greater activation in L than R SMA (p < .08). At 46 mo. post-TMS (42% named), this new LH pattern of activation continued. He improved on the Boston Naming Test from 11 pictures named pre-TMS, to scores ranging from 14 to 18 pictures, post-TMS (2–43 mo. post-TMS). His longest phrase length (Cookie Theft picture) improved from three words pre-TMS, to 5–6 words post-TMS.Pre-TMS (1.5 years poststroke), P2 had significant activation in R IFG (3% pictures named). At 3 and 6 mo. post-TMS, there was no longer significant activation in R IFG, but significant activation was present in R sensorimotor cortex. On all three fMRI scans, P2 had significant activation in both the L and R SMA. There was no new, lasting perilesional LH activation across sessions for this patient. Over time, there was little or no change in his activation. His naming remained only at 1–2 pictures during all three fMRI scans. His BNT score and longest phrase length remained at one word, post-TMS.Lesion site may play a role in each patient’s fMRI activation pattern and response to TMS treatment. P2, the poor responder, had an atypical frontal lesion in the L motor and premotor cortex that extended high, near brain vertex, with deep white matter lesion near L SMA. P2 also had frontal lesion in the posterior middle frontal gyrus, an area important for naming (Duffau et al., 2003); P1 did not. Additionally, P2 had lesion inferior and posterior to Wernicke’s area, in parts of BA 21 and 37, whereas P1 did not.The fMRI data of our patient who had good response following TMS support the notion that restoration of the LH language network is linked in part, to better recovery of naming and phrase length in nonfluent aphasia.
