Measuring impact of New Mexico prekindergarten on standardized test scores and high school graduation using propensity score matching.

The long-term impact of prekindergarten programs is an important consideration given the trend of dedicating more resources to these programs. However, long-term impact of prekindergarten programs is not well-understood and recent studies have shown preschool effectiveness can vary across states and programs. A state run prekindergarten program in New Mexico was examined using propensity score matching to minimize selection bias.

Predictors of placement stability at the state level: the use of logistic regression to inform practice.

Placement instability is often associated with a number of negative outcomes for children. To gain state level contextual knowledge of factors associated with placement stability/ instability, logistic regression was applied to selected variables from the New Mexico Adoption and Foster Care Administrative Reporting System dataset. Predictors identified in the model are consistent with previous research, reliable across time periods, and informative to the understanding of potential risk/protective factors of placement stability/instability specific to the New Mexico child welfare agency.

Cross-modal influences on representational momentum and representational gravity.

Effects of cross-modal information on representational momentum and on representational gravity (ie on displacement of remembered location in the direction of target motion or in the direction of gravitational attraction, respectively) were examined. In experiment 1, ascending or descending visual motion (in the picture plane) was paired with ascending or descending auditory motion (in frequency space); motion was congruent (both ascending, both descending) or incongruent (one ascending, one descending). Memory for visual location or auditory pitch was probed.

Boundary extension: findings and theories.

A view of a scene is often remembered as containing information that might have been present just beyond the actual boundaries of that view, and this is referred to as boundary extension. Characteristics of the view (e.g.

The onset-repulsion effect and motion-induced mislocalization of a stationary object.

The influence of a moving target on memory for the location of a briefly presented stationary object aligned with the initial location of that moving target was examined. Memory for the location of the stationary object was displaced backward (ie in the direction opposite to target motion), and memory for the initial location of the moving target was also displaced backward (consistent with an onset-repulsion effect); displacement of the stationary object did not differ from displacement of the moving target. Displacement in memory for the initial location of a moving target was not influenced by whether or not a stationary object aligned with that initial location was also presented.

A principal components analysis of dynamic spatial memory biases.

Research has shown that spatial memory for moving targets is often biased in the direction of implied momentum and implied gravity, suggesting that representations of the subjective experiences of these physical principles contribute to such biases. The present study examined the association between these spatial memory biases. Observers viewed targets that moved horizontally from left to right before disappearing or viewed briefly shown stationary targets.

Spatial memory and explicit knowledge: an effect of instruction on representational momentum.

Freyd (1987; Finke & Freyd, 1985) suggested that representational momentum (i.e., forward displacement in memory for the location of a moving target) is impervious to error feedback (i.

Multi- and unisensory visual flash illusions.

The role of stimulus structure in multisensory and unisensory interactions was examined. When a flash (17 ms) was accompanied by multiple tones (each 7 ms, SOA < or =100 ms) multiple flashes were reported, and this effect has been suggested to reflect the role of stimulus continuity in multisensory interactions. In experiments 1 and 2 we examined if stimulus continuity would affect concurrently presented stimuli.
