Pathways from Birth Weight to ADHD Symptoms through Fluid Reasoning in Youth with or without Intellectual Disability

Although individual differences in fluid reasoning reliably mediate predictions of attention-deficit/hyperactivity disorder (ADHD) symptoms from birth weight in youth with typical cognitive development (TD), it is unknown if this indirect effect operates similarly in the development of ADHD symptoms secondary to intellectual disability (ID). Thus, we evaluated mediation by fluid reasoning in a longitudinal sample of 163 youth (45% female) with (n = 52) or without (n = 111) ID who were followed prospectively from age 5 to age 13. At age 9, youth completed the Arithmetic subtest of the Wechsler Intelligence Scale for Children, a measure of fluid reasoning. At ages 9 and 13, mothers and teachers separately rated youth ADHD symptoms and mothers completed a diagnostic interview. Mediation was tested via path analysis with bootstrapped confidence intervals, and moderated mediation estimated whether indirect effects differed between ID and TD youth or based on youth IQ. Controlling for demographic factors and age 9 ADHD symptoms, age 9 Arithmetic mediated birth weight and multi-method/informant age 13 ADHD symptoms, such that birth weight positively predicted Arithmetic, which negatively predicted ADHD symptoms. Neither ID status nor IQ moderated the observed indirect effect through Arithmetic, suggesting that it was similar for ID and TD youth as well as across the range of youth IQs. These findings support previous evidence that fluid reasoning, as measured by Arithmetic, may causally mediate birth weight and ADHD symptoms, and suggest that this pathway operates similarly with respect to the development of ADHD symptoms in youth with ID.     

Military Family Advocacy in the U.S. Army: Program Service Outcomes and Family Participation

Violence in military families remains a vexing problem. Since the advent of the Global War on Terror, there is inconsistent evidence that the prevalence of family violence is increasing, particularly during and after military deployments. However, child neglect appears to increase significantly during military deployments. The military has developed family advocacy programs designed to keep families safe and intervene to reduce the deleterious effects of exposure to family violence. This is one of the first studies to examine the quality with which a family advocacy program is implemented and the degree to which families engage with the program. To conduct this study, the case files of 226 families who came in contact with the Army Family Advocacy Program (FAP) and whose cases were closed in 2013 were reviewed and coded across several implementation and service outcomes. These included involvement of qualified staff, whether or not appropriate victim and offender assessments were completed, degree of inter-agency communication, and appropriateness of referrals, among others. Soldier and family member participation in FAP and other Army-sponsored programs designed to reduce violence was also assessed. Generally speaking, the Army Family Advocacy Program was implemented with high quality, established processes and procedures for handling cases were largely followed, and FAP staff responded rapidly and thoroughly to reported abuse. However, family engagement with Army services and supports was low. Developing robust approaches to engaging families in family programming must be a high priority going forward.     

Prototypes reflect normative perceptions: implications for the development of reasoned action theory

The reasoned action approach is one of the most successful behavioral theories in the history of social psychology. This study outlines the theoretical principles of reasoned action and considers when it is appropriate to augment it with a new variable. To demonstrate, we use survey data collected from a 4 to 17 year old U.S. adolescents to test how the ‘prototype’ variables fit into reasoned action approach. Through confirmatory factor analysis, we find that the prototype measures are normative pressure measures and when treated as a separate theoretical construct, prototype identity is not completely mediated by the proximal predictors of behavioral intention. We discuss the assumptions of the two theories and finally consider the distinction between augmenting a specific theory versus combining measures derived from different theoretical perspectives.     

Sequential planning in rhesus monkeys (<Emphasis Type="Italic">Macaca mulatta</Emphasis>)

In the current study, we examined the planning abilities of rhesus monkeys (Macaca mulatta) by training them on a five-item list composed of coloured photographs and then testing them on switch and mask trials. In contrast to previous studies where monkeys made responses using a joystick, in the current study, monkeys made responses directly to a touch screen. On switch trials, after a response to the first list item, the on-screen positions of two list items were exchanged. Performance on trials in which the second and third list items were exchanged was poorer compared to normal (non-switch) trials for all subjects. When the third and fourth items were exchanged, however, only one subject continued to show performance deficits. On mask trials, following a response to the first item, the remaining items were covered by opaque white squares. When two items were masked, all four subjects responded to each masked item at a level significantly above chance. When three items were masked, however, only one subjected was able to respond to all three masked items at a level significantly above chance. The results of the present study indicate that three of our four monkeys planned one response ahead while a single monkey planned two responses ahead. The significance of these findings is discussed in relation to previous studies on planning in chimpanzees and monkeys.     

The Effects of Negative Managerial Feedback on Student Motivation: Implications for Gender Differences in Teacher–Student Relations

Research suggests that boys receive more negative teacher feedback concerning failure to follow directions, whereas girls receive more positive feedback concerning compliance (e.g., J. Brophy, 1985; K. B. Hoyenga & K. T. Hoyenga, 1993). In this study, 5th and 6th graders (79.8% Caucasian, 9.2% Hispanic, 6.1% Asian, 2.2% Pacific Islander, and 1.8% African, predominantly lower middle class) were randomly assigned to receive 1 of 5 feedback patterns. All students received positive competence-related feedback. Relative to the other conditions, the typical “male” feedback pattern decreased students' activity interest, perceived competence, and liking for the teacher. Students receiving typical “male” feedback reported less willingness to work with the teacher again; however, they did not report less willingness to work on the activity either alone or with a friend.     

When ideology matters: Moral conviction and the association between ideology and policy preferences in the Israeli–Palestinian conflict

Do people's policy preferences toward outgroups in intractable conflict consistently correspond with political ideology? To what extent are policy‐related cleavages between the political right and left in such contexts fueled by moral conviction and emotions? Analyses of a survey of Jewish‐Israelis (N = 119) conducted immediately after a war between Israelis and Palestinians revealed little to no ideological differences in acceptance of “collateral damage,” support for retribution, or support for compromise when positions about the Israeli–Palestinian conflict were devoid of moral fervor. Those on the left and right endorsed polarized policy preferences only when their positions about the conflict were held with moral conviction. Presence or absence of guilt about harm to Palestinians mediated the effects of moral conviction on policy preferences in this context. Copyright © 2013 John Wiley & Sons, Ltd.     

Grace and Christianity's Requirement: Moral Striving in Kierkegaard's Judge for Yourself!

In his later work Judge for Yourself, Kierkegaard presents a view of the Christian life that appears to counter several recent interpretations which situate Kierkegaard within a classical Protestant account of justification and sanctification. I introduce briefly these interpretations and then turn to a reading of Judge for Yourself, showing that Kierkegaard offers an account of grace and moral striving which resists these interpretations. He resists them, yet he presents a Christianity that both rejects works‐righteousness and graciously embraces those who confess their failure to do what Christianity requires.     

Structural packaging in the input to language learning: Contributions of prosodic and morphological marking of phrases to the acquisition of language

The linguistic input to language learning is usually thought to consist of simple strings of words. We argue that input must also include information about how words group into syntactic phrases. Natural languages regularly incorporate correlated cues to phrase structure, such as prosody, function words, and concord morphology. The claim that such cues are necessary for successful acquisition of syntax was tested in a series of miniature language learning experiments with adult subjects. In each experiment, when input included some cue marking the phrase structure of sentences, subjects were entirely successful in learning syntax; in contrast, when input lacked such a cue (but was otherwise identical), subjects failed to learn significant portions of syntax. Cues to phrase structure appear to facilitate learning by indicating to the learner those domains within which distributional analyses may be most efficiently pursued, thereby reducing the amount and complexity of required input data. More complex target systems place greater premiums on efficient analysis; hence, such cues may be even more crucial for acquisition of natural language syntax. We suggest that the finding that phrase structure cues are a necessary aspect of language input reflects the limited capacities of human language learners; languages may incorporate structural cues in part to circumvent such limitations and ensure successful acquisition.     

Coherent plaids are preattentively more than the sum of their parts

We investigated whether plaids activate preattentive mechanisms that are distinct from those activated by their component gratings. Observers searched for a target plaid, the sum of two perpendicular components in a circular window (radius = 0.65°). The target was present on half the trials. On all trials, half of the distractors had the same frequency and orientation as one component of the plaid, and the rest were the same as the other component. The target and the distractors were arrayed evenly on a circle (radius = 2.36°) around fixation. Target and distractor contrasts were randomly perturbed up to ±30%. The following results held for each of the 6 participants tested. (1) When F1 = 2 c/deg and F2 = 5.25 c/deg, response times (RTs) increased significantly when set size (number of distractors plus target, if present) was increased from four to eight. (2) When the spatial frequencies of both plaid components were the same (i.e., both 2 c/deg or both 5.25 c/deg), RTs increased very slightly, if at all, when set size was increased from four to eight. These results suggest the existence of a preattentive, plaid-sensitive mechanism with band-limited input that does not respond to individual grating components.     

Tuomela on deductive explanation

Almost every formal model of explanation thus far proposed has been demonstrated to be faulty. In this paper, a new model, proposed by Raimo Tuomela, is also demonstrated to be faulty. In particular, one condition of the model is shown to be too restrictive, and another condition of the model is shown to be too permissive.This research was supported by a grant from the Killam Foundation, administered by the Canada Council.
