This study tested the hypothesis that memory is a major source of variance in temporal processing. Participants categorized intervals as short or long. The number of base durations and interval types mixed within blocks of trials varied from 1 session to another. Results revealed that mixing 2 base durations within blocks increased categorization…

We tested the hypothesis that rapid eye movement (REM) sleep is important for complex associative learning by restricting rats from entering REM sleep for 4 h either immediately after training on an eight-box spatial task (0-4 REMr) or 4 h following training (4-8 REMr). Both groups of REM-restricted rats eventually reached the same overall…

In Mandarin Chinese, word meaning is partially determined by lexical tone (Wang, 1973). Previous studies suggest that lexical tone is processed as linguistic information and not as pure tonal information (Gandour, 1998; Van Lanker & Fromkin, 1973). The current study explored the online processing of lexical tones. Event-related potentials were…

Several hypotheses related to Newman's (e.g., Patterson & Newman, 1993) response modulation hypothesis were examined among adolescents with attention-deficit/hyperactivity disorder (ADHD; n = 18) and normal controls (n = 23). Consistent with predictions, youth with ADHD committed more passive avoidance errors (PAEs) than controls during the latter…

The purpose of this study was to examine the linkages among selective attention, memory bias, cognitive errors, and anxiety problems by testing a model of the interrelations among these cognitive variables and childhood anxiety disorder symptoms. A community sample of 81 youth (38 females and 43 males) aged 9-17 years and their parents completed…

The standard univariate and multivariate methods are conventionally used to analyze continuous data from groups by trials repeated measures designs, in spite of being extremely sensitive to departures from the multisample sphericity assumption when group sizes are unequal. However, in the last 10 years several authors have offered alternative…

How phonological disorders should be categorized in Turkish children remained vague for a long period of time due to a lack of normative studies. This paper reports the phonological systems of 70 phonologically disordered children, aged 4;0-8;0, in comparison with the results of a normative study of 665 Turkish-speaking children, aged 1;3-8;0. The…

This paper critically assesses the scholarship in introductory psychology textbooks in relation to the topic of latent learning. A review of the treatment of latent learning in 48 introductory psychology textbooks published between 1948 and 2004, with 21 of these texts published since 1999, reveals that the scholarship on the topic of latent…

Background: Much remains unknown about grammatical morpheme (GM) acquisition by children with moderate hearing impairment (HI) acquiring spoken English. Aims: To investigate how moderate HI impacts on the use of GMs in speech and to provide an explanation for the pattern of findings. Methods & Procedures: Elicited and spontaneous speech data were…

In this article, the authors discuss 4 critical components of mathematics assessment that relate to instruction: (a) teachers need to be knowledgeable about mathematical standards and align them with assessment; (b) assessment should combine formal and informal approaches to obtain a more authentic picture of students' performance and meaningfully…

Just as learning a first language is sometimes compared to existence within the relatively sheltered world of the Garden of Eden, the process of learning a second language is viewed as analogous to survival after expulsion from the Garden into a relatively harsh world, in which the learner must come to a conscious understanding of form and meaning…

The use of connectives in 41 academic papers written for an English writing course by Japanese students ranging from university sophomores to graduate students was examined. Connectives were categorized as additive, adversative, causal, and temporal. Each connective type was subject to certain types of error. Additive connectives tended to be…

This paper adopts the activation spreading theory to explore how lexical items are accessed. Approximately 3300 errors from both public sources and ordinary conversation in Japanese are analyzed. Analyses suggest that there are two types of environment in which contextual lexical errors occur, and that these two types of environment correspond to…

A review of the relevant literature reveals that reading reversals, whether in sequence or orientation, comprise a very small proportion of the total errors made by even poor readers. Young children tend to make more reversals, yet this tendency generally disappears with age. Top-down theorists feel that the reversal tendency of young children is…

The patterns of acquisition of the passe compose and imperfect tenses in French among 16 adult beginning and intermediate students were studied. Based on 15-minute speech samples in which both verb tenses were elicited by seeded questions and cues for descriptive and narrative monologues, the intermediate learners had greater success with the…
