Presently there is no consensus on the specific behavioral treatment of choice for targeting language in young nonverbal children with autism. This randomized clinical trial compared the effectiveness of a verbally-based intervention, Pivotal Response Training (PRT) to a pictorially-based behavioral intervention, the Picture Exchange Communication…

This is the first collection of research studies to explore the potential for mixed methods to shed light on foreign or second language learning by young learners in instructed contexts. It brings together recent studies undertaken in Cameroon, China, Croatia, Ethiopia, France, Germany, Italy, Kenya, Mexico, Slovenia, Spain, Sweden, Tanzania and…

REPORTED HERE ARE RESULTS OF A STUDY INITIATED TO EXAMINE PRINCIPLES INVOLVED IN THE EXPERIMENTAL MODIFICATION OF VERBAL BEHAVIOR. SIXTEEN UNDERGRADUATE FEMALE VOLUNTEERS WERE REQUIRED TO PRODUCE A VERBAL RESPONSE UNDER MANIPULATED LIGHTING CONDITIONS. BASE LINE SCORES WERE OBTAINED FOR EACH SUBJECT UNDER DIMLIGHT CONDITIONS. PUSHBUTTON SCORES…

The present experiment was directed at establishing the empirical relations between re-pairing and degree of training, and between re-pairing and information about that re-pairing. (Author)

The priority effect being studied is higher first-list than second-list recall induced by the absence of an immediate test on the first list. The hypothesis that this effect is caused by the subject's expectation of a later test was tested in this experiment. (Author/RM)

Research indicates that evaluative (emotional) word meaning and denotative meaning (imagery) are distinct mediational mechanisms and can be conditioned. It is hypothesized that the meaning responses can be conditioned concurrently and independently. (Editor/RK)

The subjects in two experiments learned either two successive unrelated verbal-discrimination or paired-associate tasks, with anticipation and feedback durations factorially combined (2 or 4sec). (Editor)

This experiment was directed at clarifying the role of verbal associative responses in stimulus recognition. The effects of both distinctive and equivalent verbal labels were assessed. (Author/RK)

Subjects' rehearsal strategies in learning a 32-pair mixed list of high- and low-imagery pairs of nouns during the four study trials in an alternating study/test presentation were measured. (Editor)

This experiment was designed to further investigate how noun imagery as a task variable may supplement the operation of an experimental-frequency mechanism (Ekstrand, Wallace, and Underwood, 1966) in verbal-discrimination learning. (Author)

The purpose of the present experiment was to clarify the nature of retrieving information from Long Term Storage by using forced recall as well as free recall to determine whether further search may lead to retrieval of additional repeated items. (Author/RK)

The present experiments were an attempt to clarify the mixed results on the interitem manipulation of implicit associative responses in verbal discrimination. (Author)

A technique that can be used to study the effects of low-level, rote, repetitive (Type I) rehearsal is introduced and validated. The technique is then used to investigate the relationship between the amount of Type I rehearsal and recognition memory performance. (Author/RM)

Clark's arguments for treating language materials as random rather than fixed effects are examined, and the problems with random effects designs and approximate statistical tests (quasi F-ratios) are reviewed. It is suggested that researchers use fixed factors. (Author/RM)
