The use of spatial manipulation to examine goalkeepers’ anticipation

This study investigated whether anticipation and search strategies of goalkeepers are influenced by temporally and spatially manipulated video of a penalty. Participants were clustered into three groups depending on skill: goalkeepers (n = 17), field players (n = 20) and control group (n = 20). An eye tracker was worn whilst watching 40 videos of a striker kicking to four corners of a goal in random order. All 40 videos were temporally occluded at foot-to-ball contact, and the non-kicking leg of 20 videos was spatially manipulated. Results showed that goalkeepers had significantly better predictions than the two groups with no differences between the two testing conditions. According to effect size, the percentage of fixation location and viewing time of the kicking leg and ball were greater for the goalkeepers and field players group than the control group irrespective of testing conditions. The fixations on the kicking leg and ball in conjunction with comparable predictions between spatially manipulated and control conditions suggest that goalkeepers may not rely on the non-kicking leg. Furthermore, goalkeepers appear to use a global perceptual approach by anchoring on a distal fixation point/s of the penalty taker whilst using peripheral vision to obtain additional information.     

The development of reading interest and its relation to reading ability

The development of interest in reading and its relationship to reading ability was examined longitudinally in 117 children in Grades 1–3. Interest in reading was measured by eight items from the Elementary Reading Attitude Survey. Less able readers had lower interest in reading, but their development was parallel to that of more able readers. Interest in reading in Grade 1 was weakly correlated with Grade 3 reading ability, but correlations were lower for interest measured in Grades 2 and 3. Hierarchical regression analyses indicated weak and inconsistent effects of reading interest on reading ability after controlling general cognitive ability, SES, phonological awareness and naming speed. It is concluded that interest in reading has only a weak relationship to reading ability in the early elementary years, and that much of that relationship overlaps with the effects of other more powerful predictors.

Does God Make It Real? Children’s Belief in Religious Stories From the Judeo‐Christian Tradition

Four- to 6-year-old children (N = 131) heard religious or nonreligious stories and were questioned about their belief in the reality of the story characters and events. Children had low to moderate levels of belief in the characters and events. Children in the religious story condition had higher levels of belief in the reality of the characters and events than did children in the nonreligious condition; this relation strengthened with age. Children who used God as an explanation for the events showed higher levels of belief in the factuality of those events. Story familiarity and family religiosity also affected children's responses. The authors conclude that God's involvement in a story influences children's belief in the reality of the characters and events in that story.     

Verbal-behavioral dissociations in development

Verbal and behavioral measures of children's knowledge are frequently dissociated. These situations represent a largely untapped but important resource for furthering an understanding of human cognition. In this paper, verbal-behavioral dissociations in children are discussed and analyzed, drawing from a wide range of domains. The article explores what might lead to different responses in different modalities, and it is proposed that children's goals may be an important factor. It is concluded that a variety of factors are involved in producing these dissociations, and that a richer picture of development will result from attention to these factors.     

Entertainment We Watch and Entertainment We Appreciate: Patterns of Motion Picture Consumption and Acclaim Over Three Decades

An analysis of 582 film titles spanning the years from 1980 to 2010 was conducted to examine the attributes and characteristics that predicted both viewership (e.g., box-office revenues) and critical acclaim (e.g., awards, audience ratings). Overall, viewership was highest for action/adventure films and lowest for dramas. In contrast, acclaim was highest for more dramatic fare, and for films that featured dark, contemplative, and emotional themes. The results are discussed in terms of the entertainment gratifications reflecting both enjoyment and appreciation.     

Capillary flow in sacrificially etched nanochannels

Planar nanochannels are fabricated using sacrificial etching technology with sacrificial cores consisting of aluminum, chromium, and germanium, with heights ranging from 18 to 98 nm. Transient filling via capillary action is compared against the Washburn equation [E. W. Washburn, Phys. Rev. 17, 273 (1921)], showing experimental filling speeds significantly lower than classical continuum theory predicts. Departure from theory is expressed in terms of a varying dynamic contact angle, reaching values as high as 83° in channels with heights of 18 nm. The dynamic contact angle varies significantly from the macroscopic contact angle and increases with decreasing channel dimensions.     

Thinking about Fantasy: Are Children Fundamentally Different Thinkers and Believers from Adults?

Young children are often viewed as being unable to differentiate fantasy from reality. This article reviews research on both children's and adults beliefs about' fantasy as well as their tendency to engage in what is thought of as "magical thinking." It is suggested that children are not fundamentally different from adults in their ability to distinguish fantasy from reality: Both children and adults entertain fantastical beliefs and also engage in magical thinking. Suggestions are offered as to how children and adults may differ in this domain, and an agenda for future research is offered.     

Thin film electro-osmotic pumps for biomicrofluidic applications

Electro-osmotic flow (EOF) pumps are attractive for fluid manipulation in microfluidic channels. Open channel EOF pumps can produce high pressures and flow rates, and are relatively easy to fabricate on-chip or integrate with other microfluidic or electrical components. An EOF pump design that is conducive to on-chip fabrication consists of multiple small channel arms feeding into a larger flow channel. We have fabricated this type of pump design using a thin film deposition process that avoids wafer bonding. We have evaluated pumps fabricated on both silicon and glass substrates. Consistent flow rate versus electric field were obtained. For the range of 40–400 V, flow rates of 0.19–2.30 μL∕min were measured. Theoretical calculations of pump efficiency were made, as well as calculations of the mechanical power generated by various pump shapes, to investigate design parameters that should improve future pumps.
