Argument Status and PP-Attachment

Prepositional phrase attachment was investigated in temporarily ambiguous sentences. Both attachment site (noun phrase or verb phrase) and argument status (argument or adjunct) were manipulated to test the hypothesis that arguments are processed differently than adjuncts. Contrary to this hypothesis, some previous research suggested that arguments and adjuncts are initially processed in the same manner, following a general bias to attach prepositional phrases to the verb phrase whenever possible [Clifton, Speer, & Abney (1991) Journal of Memory and Language, 30, 251–271]. The current study supports the hypothesis for differential processing, even during the initial stages of syntactic analysis. In an eye movement experiment, readers spent less first-pass time on argument prepositional phrases (PPs) than adjunct PPs. The results support a view in which a noun’s or verb’s argument structure can facilitate the analysis of its arguments.This research was supported by NSF grants SBR-9729056 and SBR-9720473 to the first author.

The effectiveness of early head start for 3-year-old children and their parents: lessons for policy and programs

Early Head Start, a federal program begun in 1995 for low-income pregnant women and families with infants and toddlers, was evaluated through a randomized trial of 3,001 families in 17 programs. Interviews with primary caregivers, child assessments, and observations of parent-child interactions were completed when children were 3 years old. Caregivers were diverse in race-ethnicity, language, and other characteristics. Regression-adjusted impact analyses showed that 3-year-old program children performed better than did control children in cognitive and language development, displayed higher emotional engagement of the parent and sustained attention with play objects, and were lower in aggressive behavior. Compared with controls, Early Head Start parents were more emotionally supportive, provided more language and learning stimulation, read to their children more, and spanked less. The strongest and most numerous impacts were for programs that offered a mix of home-visiting and center-based services and that fully implemented the performance standards early.     

A test of major assumptions about behavior change: a comprehensive look at the effects of passive and active HIV-prevention interventions since the beginning of the epidemic

This meta-analysis tested the major theoretical assumptions about behavior change by examining the outcomes and mediating mechanisms of different preventive strategies in a sample of 354 HIV-prevention interventions and 99 control groups, spanning the past 17 years. There were 2 main conclusions from this extensive review. First, the most effective interventions were those that contained attitudinal arguments, educational information, behavioral skills arguments, and behavioral skills training, whereas the least effective ones were those that attempted to induce fear of HIV. Second, the impact of the interventions and the different strategies behind them was contingent on the gender, age, ethnicity, risk group, and past condom use of the target audience in ways that illuminate the direction of future preventive efforts.     

The "frozen in time" effect in evaluations of the dead

Two experiments tested the hypothesis that evaluations of the dead are more resistant to change than are evaluations of the living. In Experiment 1, perceivers formed an impression of a target person who performed either a moral or an immoral action and then either died or remained alive. Perceivers were later given new inconsistent information about the target's morality. The results revealed that perceivers' original impressions of the target were significantly less likely to change in response to the inconsistent information when the target was believed to be dead than when she was believed to be alive. Experiment 2 replicated the effect in impressions of real-world targets. The implications of these findings for research on posthumous impression processes are discussed.     

The Evaluation of Parental Fitness in Termination of Parental Rights Cases: A Functional-Contextual Perspective

This article highlights issues involved in carrying out evaluations for termination of parental rights cases and suggests caution for mental health professionals doing such evaluations. It argues that current models of parenting that come from the child development and child maltreatment fields are too narrow in their focus to act as a foundation for such evaluations and are often based on research with select groups in our society making them open to bias. Similarly, it is argued that traditional assessment measures are limited in their utility for responding to the kinds of relational and basic care questions asked in such evaluations. A functional-contextual model is offered as an alternative with examples of potentially useful measurement strategies. With such a frame as a starting point, the field might progress to providing more useful information to courts. Future research directions to improve this practice arena are discussed.     

The Law and Information Processing: Implications for Verdicts in Rape Cases1

This study investigated the effects of focus of attention (victim vs. defendant) and the ability to recommend a sentence in addition to rendering a verdict versus rendering only a verdict on judgments in a rape case. Support was found for the hypothesis that participants would more often find the defendant guilty, and would be more confident in their guilty verdict when a sentence could be recommended in addition to the verdict, compared to those who only recommended a verdict. This pattern was especially prominent for females. This finding is discussed in terms of the standard of reasonable doubt that mock jurors may impose on their verdict decision. Interactions between the independent variables suggest that these factors may prompt mock jurors to selectively attend to particular types of information at particular times.     

Variation in performance on auditory and visual monitoring tasks as a function of signal and stimulus frequencies

Observers were required to detect double jumps of a diffuse light spot jumping in a circular pattern and more intense noise pulses in a pulse train. Seven groups performed at different combinations of stimulus and signal frequencies, higher signal frequency/stimulus frequency ratios, and lower stimulus frequencies. Stimulus frequency was a more potent determiner of performance than signal frequency, and performance was not invariant within a given signal frequency/stimulus frequency ratio. Correlations of dependent measures were also examined.-Results are discussed with reference to various theories of vigilance behavior.     

Gender bias in clinical judgment: An assessment of the analogue method's transparency and social desirability

The main purpose of this research was to determine whether clinicians discern the intent of an analogue study of gender bias in clinical judgment and, if so, whether they respond in a socially desirable manner. A total of 147 psychologists responded to a national mail survey in which they were instructed to make clinical ratings of a case summary describing either a female or male client. In one condition (the Social Desirability condition), clinicians were informed of the study's intent and instructed to respond in a socially desirable fashion. In another condition (the No Social Desirability condition), the study's intent was not revealed and clinicians were asked to guess the study's hypothesis following their ratings. Results indicate that only 10 of 100 clinicians reported having deduced the purpose of the study. The small number of guessers prohibited examination of whether guessing the intent leads to socially desirable responses. Results provide no evidence that either therapist or client gender influenced clinical judgment. Implications for evaluating experimental findings which fail to support gender bias in clinical judgment are discussed.This research was supported in part by a Biomedical Research Grant awarded to the first author when he was a faculty member at the University of Southern California. Thanks are due to Bernie Weiner and Rena Repetti for their comments on early drafts.     

Social Value Orientation and Helping Behavior1

The present study investigated the relationship between people's social value orientations and helping behavior. Subjects dassified a priori as either cooperators, individualists, or competitors were mailed a request to volunteer from zero to ten hours of their time to a worthy cause. Subjects were asked to indicate on their response forms the number of hours, if any, that they wished to contribute and to retum these forms using an enclosed self-addressed envelope regardless of whether they intended to donate any hours. The results revealed that subjects of all three social value orientations were equally likely to comply to the small request to return their response forms. However, the number of hours that subjects contributed differed as a function of their social values. As predicted, cooperators contributed significantly more of their time to the cause than did individualists and competitors. We relate these findings to previous research on social values and helping behavior.
