Abstract/Description

Prior research has explored the counterchange model of motion detection in terms of counterchanging information that originates in the stimulus foreground (or objects). These experiments explore counterchange apparent motion with regard to a new apparent motion stimulus where the necessary counterchanging information required for apparent motion is provided by altering the luminance of the background. It was found that apparent motion produced by background-counterchange requires longer frame...
Show morePrior research has explored the counterchange model of motion detection in terms of counterchanging information that originates in the stimulus foreground (or objects). These experiments explore counterchange apparent motion with regard to a new apparent motion stimulus where the necessary counterchanging information required for apparent motion is provided by altering the luminance of the background. It was found that apparent motion produced by background-counterchange requires longer frame durations and lower levels of average stimulus contrast compared to foreground-counterchange. Furthermore, inter-object distance does not influence apparent motion produced by background-counterchange to the degree it influences apparent motion produced by foreground-counterchange.

This study examined the temporal structure of children's study behaviors on a sort/recall task. Forty-two fifth-grade children were given six sort/recall trials, each consisting of a two-minute study period followed by a recall assessment. Three trials used the same word list on each trial, while three trials used different word lists on each trial. Half of the participants received the different word list trials first while the order was reversed for the remaining participants. Results were...
Show moreThis study examined the temporal structure of children's study behaviors on a sort/recall task. Forty-two fifth-grade children were given six sort/recall trials, each consisting of a two-minute study period followed by a recall assessment. Three trials used the same word list on each trial, while three trials used different word lists on each trial. Half of the participants received the different word list trials first while the order was reversed for the remaining participants. Results were analyzed for differences between recall groups, type of word list used, and presentation order of the trials. High recallers demonstrated stronger temporal patterns of study behaviors than did low recallers (as measured by Fourier analysis of time series data). High recallers also showed stronger tendencies to use behaviors that facilitated performance in close temporal proximity. Type of word list affected recall and temporal patterns of a portion of the study behaviors analyzed.
