Two experiments investigated response tendencies of preschoolers toward yes-no questions about actions. Two hundred 2- to 5-year-old children were asked questions concerning actions commonly associated with particular objects (e.g., drinking from a cup) and actions not commonly associated with particular objects (e.g., kicking a toothbrush). The…

The neurocognitive development of moral and conventional judgments was examined. Event-related potentials were recorded while 24 adolescents (13 years) and 30 young adults (20 years) read scenarios with 1 of 3 endings: moral violations, conventional violations, or neutral acts. Participants judged whether the act was acceptable or unacceptable…

Subjects responded most accurately to sentences representing temporal order and to and then but first" commands than to before/after" commands. (Author)

In two experiments, the majority of 21 newborn infants who were maintained in an alert state consistently turned their heads toward a continuous sound source presented 90 degrees from midline. For most infants, this orientation response was rather slow, taking median latencies of 2.5 seconds to begin and 5.5 seconds to end. (JMB)

This study investigated 17-week-old infants' response to discrepancy in visual patterns as a function of rate of habituation. (BRT)

Results support the contention that infant attention should be divided into separate attention-getting and attention-holding processes. (Author)

Results showed that instructions significantly increased recognition accuracy. (Author/MB)

Results were interpreted in terms of current conceptions of age differences in information-processing speed. (Author)

To characterize cognitive maturation through adolescence, processing speed, voluntary response suppression, and spatial working memory were measured in 8- to 30-year-old (N=245) healthy participants using oculomotor tasks. Development progressed with a steep initial improvement in performance followed by stabilization in adolescence. Adult-level…

Study attempts to clarify the attentional versus perceptual learning functions of presence of the discriminative stimuli during delay. (Authors)

Aim of the present study was to clarify the processes involved in the apparent lag in copying a diamond by reducing the lag experimentally with perceptual training of discrimination of orientation. (Authors)

Results suggest that the human infant's response to visual stimulation undergoes change during the neonatal period. (Authors)

An experiment was conducted comparing the effectiveness for producing response inhibition of high- and low-intensity physical punishment and elaborated verbal punishment when punishment was delivered either early or late in a response sequence. (Author)
