As modern vehicles continue to integrate increasingly sophisticated Advanced Driver Assistance Systems (ADAS) and Autonomous Vehicles (AV) functions, conventional user manuals may no longer be the most effective medium for conveying knowledge to drivers. This research analysed conventional, paper and video-based instructional methods versus a…

Item response theory (IRT) is currently the dominant methodological paradigm in educational and psychological measurement. IRT models are based on assumptions about the relationship between latent traits and observed responses, so the accuracy of the methodology depends heavily on the reasonableness of these assumptions. This dissertation consists…

Social scientists have long agreed that satisficing behavior increases error and reduces the validity of survey data. There have been numerous reviews on detecting satisficing behavior, but preventing this behavior has received less attention. The current narrative review provides empirically supported guidance on preventing satisficing by…

Proportion compatible manipulations are often used to index strategic processes in selective attention tasks. Here, a subtle confound in proportion compatible manipulations is considered. Specifically, as the proportion of compatible trials increases, the ratio of complete repetitions and complete alternations to partial repetitions increases on…

With many children and adults affected by Attention Deficit Hyperactivity Disorder, researchers strive to understand the underpinnings of ADHD and associated factors on both a basic and applied level. The goal of this volume is to explore some of the broad array of research in the field of ADHD. The 12 chapters cover a variety of topics as varied…

Three experiments assess the effects of variations of force and time on response latency on both simple and choice reaction time. The first two experiments demonstrate that, while latency does not vary as a function of force, increasing timing demands, by requiring that a response be maintained, led to increases in reaction time. These results led…

This study compared the auditory lexical decision times of children (N=46, mean age=7) with specific language impairment (SLI) to those of typically developing age peers. Although SLI children were significantly slower than peers, speed of word recognition was not correlated with measures of language comprehension for the SLI group. Possible…

This study assessed the differential effectiveness of two types of response delays on correct responding (with communicative gestures) by three individuals with severe mental handicaps to training instructions. Results showed that response delay was effective in increasing the number of correct responses in two of the three individuals. (DB)

Investigation of grammaticality judgments and decision times for 21 children in 2 age groups (ages 6-7 and ages 8-9) found good sensitivity to grammatical errors, with errors in word order more readily detected than errors of morphological selection. Older children processed errors somewhat more quickly. (Author/DB)

This study evaluated eye-blink conditioning in 11 persons with autism (ages 11 to 22). Compared to matched controls, persons with autism learned the task faster but performed short-latency, high-amplitude conditioned responses. Results suggest this population has the ability to rapidly associate paired stimuli but may have impairments in…

The article summarizes results from two experimental studies on reactivity. In the first experiment, 24 college-age participants received a computerized treatment that delivered a grammar lesson, practice, and feedback on assignment of semantic functions in Latin. Verbalizations did not induce reactivity on accuracy, but they slowed down posttest…

The growing literature on semantic memory suggests that many concepts normally believed to belong to certain semantic categories functionally belong to other categories. This determination can be explored by a variety of priming methodologies in which a subject's reaction time is analyzed while making certain judgements about a visually presented…

The study, with four mildly retarded primary-age students, found that constant time delay was an effective instructional strategy when students were taught to read sight words and that incidental learning also occurred as each student acquired some nontargeted spelling information. (Author/DB)

Fourteen right-handed stutterers and 14 normal speakers responded to monaurally presented stimuli with their right and left hands. Results suggested a bilateral model of neurolinguistic organization for stutterers in which both hemispheres must participate simultaneously in the decoding process. (Author/DB)

Examined the effects of an audiovisual distractor on the visual attention paid to TV by preschool children characterized as distractible. The effectiveness of an audiovisual distractor eliciting a head turn from the TV was diminished when TV viewing had been maintained for at least 15 seconds. (PCB)
