The current research examined how Arabic diglossia affects verbal learning memory. Thirty native Arab college students were tested using auditory verbal memory test that was adapted according to the Rey Auditory Verbal Learning Test and developed in three versions: Pure spoken language version (SL), pure standard language version (SA), and…

Purpose: The aim of this study was to determine whether the word-learning challenges associated with developmental language disorder (DLD) result from encoding or retention deficits. Method In Study 1, 59 postsecondary students with DLD and 60 with normal development (ND) took the California Verbal Learning Test-Second Edition, Adult Version…

Objective: To evaluate stimulant medication on symptoms and functioning for college students with ADHD using double-blind, placebo-controlled, crossover design. Method: Participants included 24 college students with ADHD and 26 college students without psychopathology. Lisdexamfetamine dimesylate (LDX) was examined for ADHD participants over five…

Retroactive interference (RI) in list learning occurs when the learning of a second list of words interferes with the recall of the first learned list. Having the lists be thematically different can reduce retroactive interference within list learning; however, this study demonstrates how RI can be reduced when the lists contain similar words.…

The hypothesis that describing a visual memory can result in recoding interference was investigated in a series of 6 experiments with 518 college students. Collective results were consistent with the hypothesis; verbalizing memory can produce a verbally biased memory representation that can interfere with the original visual memory. (SLD)

Subjects were given three trials to speak and to write as fast as they could both the alphabet and a set of two-digit numbers. The speed or oral responding was approximately 6 syllables per second for letters and 7 syllables per second for digits. The speed for writing was approximately 2 items per second for both digits and letters. Correlations…

A study is reported describing an output-monitoring phenomenon in free recall and establishing that subjects have accurate knowledge concerning their previous output performance. Implications with respect to other known memory phenomena are discussed. (Author/RM)

A study is described which examined the retrieval of regular and irregular past tense verbs. Results suggested that preterites such as "taught" are not stored as separate and independent lexical units but are formed from the verb stem by means of derivational rules. (Author/RM)
