The purpose of this tutorial is threefold: (a) review the state of statistical science regarding effect-sizes, (b) illustrate the importance of effect-sizes for interpreting findings in all forms of research and particularly for results of clinical-outcome research, and (c) demonstrate just how easily a criterion on reporting effect-sizes in…

Four experiments are reported in which the mechanisms underlying auditory negative priming were investigated. In Experiments 1A and 1B, preprime-prime intervals and prime-probe intervals were manipulated.The ratio between the 2 intervals determined the size of the negative priming effect. Results are compatible with the episodic retrieval account,…

Rhesus monkeys were trained and tested in visual and auditory list-memory tasks with sequences of four travel pictures or four natural/environmental sounds followed by single test items. Acquisitions of the visual list-memory task are presented. Visual recency (last item) memory diminished with retention delay, and primacy (first item) memory…

The authors examined the effectiveness of self-monitoring for increasing the rates of teacher praise statements and the acceptability of using this technique for teachers. The participant was a first-year teacher of high school students with emotional and behavioral disturbances. The authors completed this study in an ABA maintenance design. They…

Information that is spaced over time is better remembered than the same amount of information massed together. This phenomenon, known as the spacing effect, was explored with respect to its effect on learning and neurogenesis in the adult dentate gyrus of the hippocampal formation. Because the cells are generated over time and because learning…

The Predominantly Inattentive (PI) and Combined (CB) subtypes of AD/HD differ in cognitive tempo, age of onset, gender ratio, and comorbidity, yet a differentiating endophenotype has not been identified. The aim of this study was to test rigorously diagnosed PI, CB, and typical children on measures selected for their potential to reveal…

The intent of this study is to learn about principal intern perceptions of their grasp of the identified state principal standards for Colorado. A non-experimental comparative approach was used for this inquiry. Interns were trained to use an online journaling process called Journey Mapping. On a six point scale they rated themselves on their…

The authors of this article examine the analytic and reporting features of research articles cited in "Studying Teacher Education: The Report of the AERA Panel on Research and Teacher Education" (Cochran-Smith & Zeichner, 2005b) that used quantitative reporting practices. Their purpose was to help to identify reporting practices that can be…

The possibility of a time sensitive relationship between scores on the Dean Miholasky precognition test and those on Activity 2 of the Torrance Test for Creative Thinking was investigated with 58 freshmen students in a school of engineering. The Torrance Test consists of three activities that present a series of figural stimuli to the subject who…

A method of interpolation has been derived that should be superior to linear interpolation in computing the percentile ranks of test scores for unimodal score distributions. The superiority of the logistic interpolation over the linear interpolation is most noticeable for distributions consisting of only a small number of score intervals (say…

Fifteen moderately or severely retarded adults listened to music and looked at slides in baseline schedules, reinforcement schedules, and control phases with no contingent relation between responses. Individual analysis of instrumental responding indicated increases in schedules that produced response deprivation, but only once in schedules that…

Reported are effects of an 8-week running program on the cardiorespiratory fitness of normal 10- to 12-year-old males. (GW)

Study was designed to extend previous studies on note taking and listening by investigating the effects of thematic relatedness and of opportunity for consolidation on the learner's recall. (Authors)

Learning occurred faster with a fixed input grouping sequence than with a changing sequence. (Authors)

Study found that stimulus presence during a delay of reinforcement interval enhanced performance, and to a large extent prevented the usual delay-produced decrement. (Authors)
