Two experiments were conducted to examine the effects of justice motivation and the presentation of the victim on the willingness of individuals to extend help to innocent victims. (Editor)

The present study examined the immediate and delayed effects of unobtrusive exposure to personality trait terms (e.g., "reckless,""persistent") on subjects' subsequent judgments and recollection of information about another person. The implications of individual and situational variation in the accessibility of different categories for judgments…

This research model studies the behavioral impacts of consultative knowledge based systems (KBS). A study of graduate students explored to what extent their decisions were affected by user participation in updating the knowledge base; ambiguity of decision setting; routinization of usage; and source credibility of the expertise embedded in the…

Discusses the scarcity of research on the characterization of the second-language (L2) initial state, where "L2 initial state" refers to the starting point of nonnative grammatical knowledge. The article emphasizes that exploring the mechanisms of "development" of interlanguage requires an understanding of what a particular stage changed "from."…

Examines the hypotheses about how print represents the speech that preliterate children select when they receive input compatible with several such hypotheses. Results indicate that most preliterate children do not select phonologically based hypotheses, but instead focus on morphophonology and/or semantic aspects of words' referents. (40…

Evaluates arguments advanced in favor of special nativism in second-language acquisition (SLA). The article considers the following claims: Universal Grammar (UG) is the null hypothesis; any theory of SLA needs a theory of grammar; and showing that interlanguage grammars are underdetermined by the available input implies that UG must be accessible…

This article first outlines the logic of null hypothesis testing and the problems of using it to evaluate special education research. It then presents three alternative metrics, a binomial effect size display, a relative risk ratio, and an odds ratio, that can better identify important treatment effects using illustrative data from recently…

Examines the nature of observational science and cites its role as a foundation for subsequent scientific research. Uses a case history to illustrate the interplay of observation, problem recognition, and hypothesis testing. (DDR)

Observed a high rate of congruence between a hypothesized theoretical model of cognitive, motivational, and volitional dimensions of learning and empirical data from 614 college students. Analysis of effects between the model variables reveals some interesting effects with implications for student academic achievement. (SLD)

Investigates the extent to which a representation of relative force can account for children's understanding of epistemic modals when their logical meaning is considered. Results confirm the influence of relative force and suggest that deductive inference is an early semantic component of modal terms. (29 references) (Author/CK)

Describes English-speaking children's acquisition of voice onset time. The study evaluated two hypotheses, one predicting that children would control the vowel duration contrast earlier than the consonantal one and one predicting that they would control the contrast represented on the segmental level of linguistic description earlier than the…

Presents results of a response latency (RL) experiment with English-speaking learners of German that investigated to what extent if any two different groups of second language learners permit raising of the thematic verb. Results show that learners respond in different ways to stimulus sentences with raised and unraised verbs depending on the…

Explored issue of confirmatory bias in counselors' clinical hypothesis testing by examining the way counselors (n=84) remembered information about a client. Results indicated counselors remembered more confirmatory than discomfirmatory information. Suggests counselors need to be aware of these biases and should be trained to avoid them.…

The primary language hypothesis of short-term memory coding was challenged by an experiment with eight normally hearing college students and a review of the literature about deaf subjects. Whether or not deaf signers recode printed words into sign depends on a variety of task and subject factors. (SLD)

A strategy for evaluating/modifying covariance structure models (CSMs) is presented. The approach uses recent developments in estimation under nonstandard conditions and unified asymptotic theory related to hypothesis testing, and it determines the extent of sample size sensitivity and specification error effects by relying on existing statistical…
