Effect of Dimensional Preference on Adult Shift Learning: Some Developmental Implications
Peer reviewed Peer reviewed
Esposito, Nicholas J. – Developmental Psychology, 1975
Experiment 1 examined the relationship between dimensional preference and proportion of optional reversal shifts among adults. Experiment 2 examined dimensional preference and shift behaviors using an intradimensional-extradimensional shift paradigm. The results indicate that adults show the same type of behavior previously throught to…

Encoding Dimensions in Memory: Developmental Similarities at Two Grade Levels
Peer reviewed Peer reviewed
Geis, Mary Fulcher – Developmental Psychology, 1975
Second and sixth grade children's relative sensitivity to acoustic, semantic, and physical dimensions was inferred from the amount of release from proactive interference obtained for shifts along each dimension. (ED)

The Development of Infant Discrimination of Affect in Multimodal and Unimodal Stimulation: The Role of Intersensory Redundancy
Peer reviewed Peer reviewed
Direct linkDirect link
Flom, Ross; Bahrick, Lorraine E. – Developmental Psychology, 2007
This research examined the developmental course of infants' ability to perceive affect in bimodal (audiovisual) and unimodal (auditory and visual) displays of a woman speaking. According to the intersensory redundancy hypothesis (L. E. Bahrick, R. Lickliter, & R. Flom, 2004), detection of amodal properties is facilitated in multimodal stimulation…

Optional Reversal Probability is a Linear Function of the Log of Age
Peer reviewed Peer reviewed
Kendler, Tracy S.; Ward, James W. – Developmental Psychology, 1972
The orderly increase in the proportion of subjects who make optional reversal shifts over an age scale that now encompasses a range from 3 to 18 is confirmed. (Authors)

Infants Flexibly Use Different Dimensions to Categorize Objects
Peer reviewed Peer reviewed
Direct linkDirect link
Ellis, Ann E.; Oakes, Lisa M. – Developmental Psychology, 2006
A sequential-touching task was used to investigate whether 14-month-old infants can rapidly change how they categorize a set of objects, recognizing new groupings of objects they had previously categorized in a different way. When presented with a collection of objects that could be categorized by shape (balls vs. blocks) or material (soft vs.…

Quantitative Models for Children's Concept Learning from a Developmental Perspective
Peer reviewed Peer reviewed
Block, Karen K.; And Others – Developmental Psychology, 1973
Results showed that reversal shift was easier than extradimensional shift and that relative shift difficulty was unaffected by instructions, in contrast to findings with college-age subjects. (Authors)
