Escape from the Island: Grammaticality and (Reduced) Acceptability of wh-island Violations in Danish

In the syntax literature, it is commonly assumed that a constraint on linguistic competence blocks extraction of wh-expressions (e.g. what or which book) from embedded questions, referred to as wh-islands. Furthermore, it is assumed that there is an argument/adjunct asymmetry in extraction from wh-islands. We report results from two acceptability judgment experiments on long and short wh-movement and wh-extraction from wh-islands in Danish. The results revealed four main findings: (1) No adjunct/argument asymmetry in extraction from wh-islands. (2) Long adjunct wh-movement is less acceptable than long argument wh-movement, and this difference is attributable to matrix verb compatibility and factivity, not D-linking. (3) Long movement reduces acceptability, but is more acceptable than island violations. (4) Training effects reveal that island violations, though degraded, are grammatical in Danish. Since the standard assumptions cannot account for the range of results, we argue in favor of a processing account referring to locality (processing domains) and working memory.     

Monte Carlo tests of the Rasch model based on scalability coefficients

For item responses fitting the Rasch model, the assumptions underlying the Mokken model of double monotonicity are met. This makes non‐parametric item response theory a natural starting‐point for Rasch item analysis. This paper studies scalability coefficients based on Loevinger's H coefficient that summarizes the number of Guttman errors in the data matrix. These coefficients are shown to yield efficient tests of the Rasch model using p‐values computed using Markov chain Monte Carlo methods. The power of the tests of unequal item discrimination, and their ability to distinguish between local dependence and unequal item discrimination, are discussed. The methods are illustrated and motivated using a simulation study and a real data example.     

Adolescent Motivations to Engage in Pro‐Social Behaviors and Abstain From Health‐Risk Behaviors: A Self‐Determination Theory Approach

The present study used self‐determination theory to examine adolescents' motivations to engage in charitable donating and community volunteering and to abstain from sexual intercourse and marijuana use. The sample consisted of 419 late adolescents recruited from across the country through an online survey panel. Participants completed online measures of motivations to engage in donating and volunteering, motivations to abstain from sex and marijuana, and single‐item indexes of the four behaviors. Variable‐centered analyses (correlation and regression) found evidence for a general motivational factor, motivational specificity by behavioral domain (positive and negative behaviors), motivational specificity by particular behavior (charitable donating, volunteering, sexual risk‐taking, and marijuana use), and a stronger relative role for autonomous motivations than controlled motivations. Person‐centered analyses (cluster analysis) found four motivation profiles (low motivation, medium motivation, high motivation, and mixed motivation) for all four behaviors and suggested that level of autonomous motivation was a key factor differentiating the groups on levels of behavior. The findings suggest different levels of motivational specificity and highlight the importance of autonomous motivations in predicting behaviors as compared to controlled motivations. Further, similar patterns were found for motivations to engage and to abstain.     

Social change in the aftermath of successful minority influence

This chapter describes a programme of research on group dynamics in the aftermath of successful minority influence that reverses minority and majority positions within a group. Supporting the authors' gain - loss asymmetry model of change, converging evidence suggests that loss of the majority position generates strong disidentification from the superordinate group whereas gaining the majority position does not yield comparable identification. This overall decrease in identification is associated with a general increase in hostility, reduced helpfulness, and a desire to exit the group. Thus groups may be especially fragile following internal changes in the majority - minority positions. Additional research suggests that such a pattern of reactions to majority - minority change is a specifically group phenomenon (versus aggregates of individuals) and occurs when majority - minority reversals follow the attitude change of existing group members (versus an influx of new members). New majorities will increase their identification with the group when converts provide genuine support or when their new majority position persists over time. Implications of these findings for intra-group relations in the aftermath of social change are discussed.     

Type of hemodialysis and preference for behavioral involvement: interactive effects on adherence in end-stage renal disease

Examined the effects of hemodialysis type (i.e., staff controlled, in center vs. patient controlled, home) and patient preference for behavioral involvement on adherence and emotional adjustment in a sample of 53 patients with end-stage renal disease. Consistent with person x treatment interaction models, higher levels of preference for behavioral involvement were associated with better dietary adherence (i.e., lower serum potassium) for patients receiving dialysis at home but worse dietary adherence for patients receiving treatment in a dialysis center. A similar though weaker patient x treatment type matching pattern was observed for fluid-intake adherence (i.e., interdialytic weight gain). No effects were observed for patients' self-reported depression levels. Possible mechanisms for the interactional effect on adherence are discussed.     

Clarifying problems and offering solutions for correlated error when assessing the validity of selected-subtest short forms

The correlation between a short-form (SF) test and its full-scale (FS) counterpart is a mainstay in the evaluation of SF validity. However, in correcting for overlapping error variance in this measure, investigators have overattenuated the validity coefficient through an intuitive misapplication of P. Levy's (1967) formula. The authors of the present article clarify that such corrections should be based on subtest-level versus FS-level data. Additionally, the authors propose a simple, modified equation incorporating FS-level scores that provides liberal and conservative validity measures for comparison across estimation methods, and they demonstrate its use in both a normative (N = 2,450) and clinical psychiatric (N = 216) sample.
