Methods The present study utilised data from the Canadian National Longitudinal Survey of Children and Youth (NLSCY), from 1995 to 2009. Using a single yes/no question that asked “Has [the child]/have you ever experienced being hungry because the family has run out of food or money to buy food?,” the authors sought to assess how reports of hunger were associated with depression self-reported ac...

This paper describes the principal features of the intonational system of Chickasaw, a Muskogean language spoken in southcentral Oklahoma. Results of the study are as follows. The Intonational Phrase (IP) consists of one or more Accentual Phrases (AP) which can be larger or smaller than a word. The underlying tonal pattern of the AP is [LHHL]. Chickasaw statements are characteristically marked ...

Marshallese, an Oceanic language spoken on the atolls of the Marshall Islands, has a question particle, ke, which may appear in one of a number of positions in yes/no interrogatives. Interestingly, the availability of certain positions depends upon whether the sentential context is affirmative or negative. In (1), we demonstrate the various grammatical and ungrammatical positions of ke in affir...

Current prediction models for risk of cardiovascular disease (CVD) incidence incorporate smoking as a dichotomous yes/no measure. However, the risk of CVD associated with smoking also varies with the intensity and duration of smoking and there is a strong association between time since quitting and the risk of disease onset. This study aims to develop improved risk prediction equations for CVD ...

OBJECTIVE We investigated elementary school children's ability to use a variety of Likert response formats to respond to concrete and abstract items. METHODS 111 children, aged 6-13 years, responded to 2 physical tasks that required them to make objectively verifiable judgments, using a 5-point response format. Then, using 25 items, we ascertained the consistency between responses using a "go...

We investigated the temporal properties of the red - green, blue-yellow, and luminance mechanisms in a contour-integration task which required the linking of orientation across space to detect a 'path'. Reaction times were obtained for simple detection of the stimulus regardless of the presence of a path, and for path detection measured by a yes/no procedure with path and no-path stimuli random...

Performance on any perceptual task depends on both the perceptual capacity and the decision strategy of the subject. We provide a model to fit both aspects and apply it to data from rats performing a detection task. When rats must detect a faint visual target, the presence of other nearby stimuli ("flankers") increases the difficulty of the task. In this study, we consider two specific factors....

The detectability of a tone added to a masker is superior when the detection trial is preceded by the masker than the signal-plus-masker. This auditory enhancement can withstand long temporal gaps between the precursor and the trial, suggesting that for yes/no trials sensitivity may depend on the stimulus presented in the prior trial. The results from an experiment examining the detectability o...

OBJECTIVE Two studies examined the effects of the oath or reassurance ("truth induction") on 5- to 7-year-old maltreated children's true and false reports of a minor transgression. METHODS In both studies an interviewer elicited a promise to tell the truth, reassured children that they would not get in trouble for disclosing the transgression, or gave no instructions before questioning the ch...

PURPOSE Using the Problem Oriented Screening Instrument for Teenagers (POSIT), the effect of mode of administration on (1) students' willingness to disclose sensitive information and (2) response rates was investigated. DESIGN A 2 × 2 unequal N factorial analysis of variance (ANOVA) design was employed. Mode of administration (paper-and-pencil vs. Web-based) was crossed with grade level (midd...
