Categorization researchers typically present single objects to be categorized. But real-world categorization often involves object recognition within complex scenes. It is unknown how the processes of categorization stand up to visual complexity or why they fail facing it. The authors filled this research gap by blending the categorization and…

The hypothesis that free recall curves reflecting effects of serial position, presentation time and delay of recall are attributable to subjects' pattern of rehearsal was explored. Experiments varied the patterns of rehearsal to examine the effects on recall. (CHK)

Short-term retention of temporal and spatial order information were compared using the distractor paradigm. Use of phonemic coding and coding of information about temporal-spatial patterns were interrupted to observe subject's reaction and ability to recall. (CHK)

The visual scanning of redundant and random spatial configurations of two-digit numbers was investigated in a target recognition task. The experimental technique involved a brief exposure of a probe (a two-digit number) at the center of the visual field, followed by a spatial pattern of 16 two-digit numbers which included the matching target in…

A set of studies investigated the relative importance of operative schemes and figurative (rote) memory. In Study I, 60 concrete operational children from grades 1-4 were asked to reconstruct two types of stimuli from memory. In order to separate the effects of operative and figurative skill use, learning disabled children with poor figurative…

A study of the speech process was conducted. The process is described as one closely linked to the one involved in the problem of the serial order in behavior. It is pointed out that in the speech of young children the grammatical relations that are properties of elementary underlying sentences appear in the grammatical meanings. Six examples of…

A significant positive correlation between multiple classification was found, in testing 65 children aged 6 to 8 years, at the stage of concrete operations. This is interpreted as support for the existence of a structure d'ensemble of operational schemes in the period of concrete operations. (Authors)

The motion variable in the learning process was investigated in three parallel experiments (science, motor skills, social studies), each designed to meet instructional objectives of fact learning, serial ordering, and concept learning. Stimulus sequences were shown as motion pictures, sequenced still pictures, or single still pictures to 582…

Purpose of this study was to determine whether instructional sequencing would affect learning from a logical structure when certain artifacts, which may have operated in previous studies, were removed. (Authors)

Reviews evidence against theories about preschool childrens' egocentricity and cognitive ineptness in the areas of classification, communication, number and order concepts, memory skills, and capacity for reasoning about causal relationships. Holds that preschoolers have been misunderstood because researchers tend to approach them with tasks…
