Color logic of apparent motion

Two shapes of either the same or different color will seem to be in smooth apparent motion with like-colored mates, at proper conditions of flash timing and spacing. An experiment is reported in which the condition was tested for unlike-colored pairs, for example red-green alternated with green-red. The question of interest was how the visual system would resolve the disparity of color. An 'intelligent' solution would rotate the shapes in three dimensions. Like-colored and unlike-colored parts were found to move and transform similarly, however, the resolution being dependent more upon timing than upon color. The motion of intelligence as it might be applied to vision is discussed in light of these results.     

Serial pattern learning by event observation.

Serial pattern learning was investigated in a variation of the task introduced by Nissen and Bullemer (1987). We presented an asterisk at 1 of 4 spatial locations on each trial, and Ss either responded with a keypress or observed the event. The first 4 blocks contained 10 repetitions of a 10- or 16-element pattern, and the 5th block contained a random sequence. The difference in response time on the 5th random block and the previous patterned block served as an indirect measure of pattern learning. A direct measure was obtained in a final test block in which Ss predicted the next asterisk position. Equivalent learning occurred for responding and observing with indirect measures, but observation was superior with direct measures. These findings indicate that knowledge of serial order can develop through simple perceptual experience, and this is more available to deliberate recall than is knowledge acquired while responding.     

Measurement Equivalence of 360°-Assessment Data: Are different raters rating the same constructs?

This study uses data collected using a 360°-assessment instrument to investigate the structural equivalence of 360°-assessment ratings, according to rater type, controlling for organizational level. Data from 533 managers and their raters were employed in the study, which used multi-group structural equations modeling. Issues central to the implementation and use of 360°-assessment data are also considered within the context of current research and practice.     

Flexible Work Arrangements Availability and their Relationship with Work‐to‐Family Conflict,Job Satisfaction,and Turnover Intentions: A Comparison of Three Country Clusters

The present study explored the availability of flexible work arrangements (FWA) and their relationship with manager outcomes of job satisfaction, turnover intentions, and work‐to‐family conflict (WFC) across country clusters. We used individualism and collectivism to explain differences in FWA availability across Latin American, Anglo, and Asian clusters. Managers from the Anglo cluster were more likely to report working in organisations that offer FWA compared to managers from other clusters. For Anglo managers, flextime was the only FWA that had significant favorable relationships with the outcome variables. For Latin Americans, part‐time work negatively related with turnover intentions and strain‐based WFC. For Asians, flextime was unrelated to time‐based WFC, and telecommuting was positively associated with strain‐based WFC. The clusters did not moderate the compressed work week and outcome relationships. Implications for practitioners adopting FWA practices across cultures are discussed.     

The child verbal competence effect in court: a comparative study of field investigative interviews of children in child sexual abuse cases

The purpose of this study is to compare field investigative interviews of children (FIIC) with three different legal outcomes in child sexual abuse cases: (i) insufficient evidence to proceed (IEP); (ii) convictions; or (iii) acquittals by the court. One hundred FIIC were divided into one of the three outcome possibilities. Amongst the female interviewees older than 10 years, there were no cases of acquittals and the convicted cases were over-represented. The children's response to open questions was found to be the main difference between the three FIIC outcomes. The responses to these open questions were 1.9 and 2.3 times longer in the convicted cases compared to acquittals and IEP. Possible explanations for the result are discussed.
