One hundred and sixty subjects from five age levels ranging from 3 to 20 years compared photographs of dogs (e.g., two different Great Danes or a Great Dane and a Doberman pinscher) and judged whether they were similar or different. (Author/MP)

Assesses whether a model of at least two levels of perspective-taking ability beyond egocentrism provides a more adequate account of the variance in subjects' responses across perspective-taking tasks. (Author/MP)

Two experiments, consisting of eight set operation tasks, were conducted to examine rule-learning in children. Subjects were 179 boys ranging in age from 7.9 to 15.4 years. (MP)

Techniques of presenting information temporally in the auditory and visual modalities and spatially in the visual modality were used to assess information processing in seven- and nine-year-old children. (JMB)

A sorting presentation procedure was used to study the effects of three classification schemes (self-generated, thematic, or taxonomic) on the organized free recall of second and fifth graders. (Author/SB)

Classified children's use of cognitive strategies on a multitrial sort-recall task. Compared to fourth graders, more second and third graders were classified utilizationally deficient; fourth graders were more likely to be classified as quasi-utilizationally deficient. Levels of recall and clustering were higher for younger utilizationally…

Predictions about reaction times (RT) from Siegler's model were tested for the balance scale task with 6- to 22-year-olds. Regression analyses provided additional knowledge of the rules. Rule II was reformulated as a rule that always involves the encoding but not always the correct application of the distance rule. RTs provided evidence for use of…

Examines age differences in, and associations among, children's attitudes and intentions regarding alcohol and cocaine use and possible cognitive underpinnings of such orientations. Attitudes and intentions were negative and became less negative with age for alcohol, but more negative with age for cocaine. The cognitive predictors contributed to…

A total of 46 preschoolers were asked to decide whether two rows of drawings of objects were exactly the same. Results revealed that preschoolers can gather information systematically, and that by age four, the majority are producing, and benefitting from, a strategy that is very efficient for same-different tasks.

Replies to the commentary by Olson and Salter on an article by Feldman and others, both reported in this issue. Maintains that the evidence does not support Olson's and Salter's conjecture that the source of age-distinctive lexical differences reported in the Feldman study is a simple function of word frequency. (BC)

Three studies found that there was a marked increase with age from preschool to adulthood in individuals' tendency to say that persons always have some thoughts and ideas flowing through their minds. Four year olds tended to say that persons could keep their minds completely empty of ideas. (MDM)

Tested adults and children (age 6 to 16 years) on 4 speeded tasks that included 19 experimental conditions. The 6- to 16-year olds' response times decreased with age as a function of adults' response times. (MM)

Investigated children's representational ability as a cognitive factor underlying the suggestibility of their eyewitness memory. Found that the eyewitness memory of children lacking multirepresentational abilities or sufficient general memory abilities (most 3- and 4-year-olds) was less accurate than eyewitness memory of those with…

Investigated preschoolers' responses to ambiguous descriptions of location. Ambiguous ("in one of the bags") descriptions caused longer search latencies in four- and five-year olds than nonambiguous descriptions ("in the bag by the chair"). The reverse was true for three-year olds. Results suggest that changes in information…
