Apparently contradictory findings regarding the locus of information processing differences between retarded and nonretarded persons were discussed. (Author)

Two experiments found that integration of facts alleviates interference only when a person can perform a memory task by making a consistency judgment and can avoid the need to retrieve a specific fact. People judge themes rather than facts: the more themes associated with a concept, the greater the interference. (Author/RD)

The semantic memory search process was examined in second graders (N=30) under an induced imagery and a control condition. (MP)

This study examined the effects of the cochlear hearing loss of 12 adults on two measures of sequential processing that rely on spectro-temporal information: a gap-detection discrimination task and a melody recognition task. It was concluded that cochlear hearing loss deleteriously affects the processes underlying perceptual organization of…

Assesses the effect of delay between an event and new postevent information related to it in six-month-old infants' memory. Three phenomena were studied: memory impairment, memory facilitation, and categorization. Suggests that postevent information has different qualitative effects depending on its timing, and provides a basis for understanding…

The vigilance of young adults with and without mild mental retardation (MR) was compared, with subjects performing two memory demanding, cognitively based tests. The vigilance decrement of MR adults declined more rapidly than did the vigilance of non-MR adults, due to an interaction between target detectability and response bias, and poor target…

A new theoretical analysis of the stop-signal model is proposed. Within the concepts of crude- and net-hazard functions, the nonobservable control-latency distribution can be estimated from observable reaction times. This result allows a test of the Logan and Cowan model (1984) without simplifying assumptions. (SLD)

Naming speed skills of 45 dyslexic children (mean ages=8, 13, and 17) and slow learning children (mean age=10) were compared with those of normally achieving children. Results indicated that children with dyslexia and slow learners have persistent and severe problems in naming speed for all stimuli, regardless of whether the stimulus requires…

The relationship between speed of information processing (SIP) and psychometric intelligence was investigated by giving 60 college students (22 males and 38 females) 2 choice reaction time (RT) tests (modified Hick paradigm) and Raven's Advanced Progressive Matrices. Results support an association between intelligence and SIP. (SLD)

Children and adults were tested on a mental rotation task in which letters were presented in different orientations. The task was performed by itself or with a memory task. Results indicated that the relation of response time to stimulus orientation in the rotation task was the same in both conditions. (BC)

Results of a literature review were organized into a taxonomy of distance learning strategies: (1) cognitive (rehearsal, elaboration, organization); (2) metacognitive (planning, monitoring, regulating); and (3) resource management (time management, study environment, effort management, social support). (Contains 24 references.) (SK)

Examined articulation and interarticulation (pause) times on Rapid Automatized Naming Tests for first- and second-graders. Found that pause and articulation times for RAN letters and objects were not reliably related, compared to RAN numbers articulation and pause durations. Subtest pause durations were differentially related to reading. RAN…

Administered 2 elementary cognitive task (ECT) tests and 2 psychometric intelligence tests to 169 monozygotic and 131 dizygotic pairs of twins in Germany. Reaction times correlated negatively with psychometric intelligence, and habitability estimates were substantial for both psychometric intelligence and reaction times on the ECTs. Multivariate…

Considers an interactive non-linear time approach, providing a personal reflection of one individual's learning time, reflective time, reconstructed meanings and personal reorganizations. Moves from experience as an English teacher to a reflective experience, to a current state of ongoing reorganization of the signs, indices, and symbols of what…

A study investigated phonological processing skills of 28 undergraduates with dyslexia. When compared to 31 controls, subjects performed significantly less well on standardized measures of reading and spelling but in the average range. Controls, however, performed significantly better on all phonological processing measures, particularly those…
