Increases in cyclic adenosine monophosphate (cAMP) are proposed to initiate learning in a wide variety of species. Here, we measure changes in cAMP in the olfactory bulb prior to, during, and following a classically conditioned odor preference trial in rat pups. Measurements were taken up to the point of maximal CREB phosphorylation in olfactory…

A total of 45 fifth grade students were the subjects of an experiment offering support for a component of learning strategy (memory imagery). Various theoretical explanations of the image-tracing phenomenon are considered, including depth of processing, dual coding and frequency. (MS)

Thirty 4- and 5-year-olds with specific language impairment (SLI) and 30 normally developing peers participated in a discrimination learning-shift paradigm. Both groups were equally successful in extracting regularities from recurring nonverbal stimuli and in making shifts. Findings failed to provide evidence that children with SLI are less able…

Infants ranging in age from six months to eight months were shown repeated instances of real object movement-disappearance-reappearance. Results suggest that the key changes in early cognitive development rest primarily upon the infant's gradual adaptation of old responses through encounters with new events--rather than upon the acquisition of…

Human recognition behavior is influenced by the phenomenon of shape constancy, which occurs when the shape of an object is correctly perceived regardless of the orientation of the object in space. The research reported here tests the validity of the shape-slant invariance hypothesis, a theoretical formulation of the phenomenon of shape constancy.…

When an odor is paired with a delayed illness, rats acquire a relatively weak odor aversion. In contrast, rats develop a strong aversion to an olfactory cue paired with delayed illness if it is presented simultaneously with a gustatory cue. Such a conditioning effect has been referred to as taste-potentiated odor aversion learning (TPOA). TPOA is…

The present study was aimed at simultaneously determining on the same subject, the effects of stress on retrieval of flexible (contextual or temporal) or stable (spatial) information. Three behavioral paradigms carried out in a four-hole board were designed as follows: (1) Simple Discrimination (SD), in which mice learned a single discrimination;…

Previous experiments with nursery school children have suggested that (1) subjects of preschool age do not verbalize during transfer learning or that (2) for these subjects, self-produced verbal cues have little influence on the learning process. To investigate the relative merits of these alternative positions, research was conducted among 80…

One hundred twenty-eight preschool boys were subjects in a 4x2x2 factorial design to investigate the change in reinforcer efficacy as a function of prior stimulus exposure. The factors were: (1) amount of repetition, 5, 25, 45, or 65; (2) reinforcer, good or bell; and (3) satiator, good or bell. Two additional groups were run as control groups to…

Literature dealing with the disadvantaged is cursorily reviewed and questions raised by the literature are considered. Specifically, this study concerns the relationship between social class and the rate of processing of visual information in young children. Although various sources of slowness in learning are mentioned, this study focused only on…

The frequency theory of verbal discrimination learning makes no distinction between silent and spoken rehearsal. Further, the frequency theory predicts that the study-test method of list presentation is superior to the anticipation method. College students, performing under silent and spoken rehearsal conditions, learned 16 low-frequency…

A study is undertaken to determine whether the nonlinguistic priority of the agent of an action facilitates the comprehension of word reference. The subjects were twelve male and twelve female infants at the one word stage of language production. The children were presented with three nonsense names (presented as part of a narration of a filmed…

This bibliography with 1,273 entries is an updated supplement to the preliminary 1997 bibliography on informal adult learning. It is a useful resource guide for those interested in publications (e.g. academic papers, government reports, grassroots publications) aimed at furthering understanding of how learning and teaching takes place in different…
