Children are both shrewd about whom to copy-they selectively learn from certain adults-and overimitators-they copy adults' obviously superfluous actions. Is overimitation also selective? Does selectivity change with age? In two experiments, 161 two- to seven-year-old children saw videos of one adult receiving better payoffs or more bystander attention than another. Children then watched the adu...

The Risk-Need-Responsivity (RNR) framework is regarded as the forefront of offender rehabilitation in guiding youth offender risk assessment and interventions. This article discusses the juvenile justice system in Singapore and the local research that has been conducted in relation to the RNR framework and the associated Youth Level of Service (YLS) measures. It describes a journey that saw the...

There is much behavioral and neurophysiological evidence in support of the idea that seeing a tool activates motor components of action related to the perceived object (e.g., grasping, use manipulation). However, the question remains as to whether the processing of the motor components associated with the tool is automatic or depends on the situation, including the task and the modality of tool...

People are most likely to see something if their gaze is directed at it. Thus if they saw something they may be biased towards believing that they had been looking at it. In order to examine whether this is so we asked participants where a target that jumped to a new position every 250 ms had been at a moment indicated by a flash or a tone. The jumping introduced uncertainty about where the tar...

Infants' memories are highly specific to their training stimuli; they rarely transfer learned responding. In two experiments, we asked whether sensory preconditioning facilitates the transfer of deferred imitation. In Experiments 1A and 1B, 6-month-olds were simultaneously preexposed to Puppets A and B and then saw target actions modeled on Puppet A. The infants associated the paired puppets an...

Micrometer-scale acoustic waves are highly useful for refined optomechanical and acoustofluidic manipulation, where these fields are spatially localized along the transducer aperture but not along the acoustic propagation direction. In the case of acoustic tweezers, such a conventional acoustic standing wave results in particle and cell patterning across the entire width of a microfluidic chann...

he producers include such individuals as composers and perormers for whom the main product either is creation of a new usical idea by the composer or re-creation of another’s novel dea by the performer—a subclassification that becomes impreise when the performance of music, itself, has a substantial reative component such as jazz. Furthermore, the expressive rges of composers have led to elabor...

The study investigated the effect of observational goals (i.e., impression formation and memory) on the process of observing ongoing behavior of others. Specifically, the amount of behavior extraction was studied. Forty-nine subjects were randomly assigned to impression and memory groups, and asked to watch a ten-minute video clip featuring a male actor in daily activities. The subjects in the ...

This contribution reports the results of the SHREC 2008 track on Stability on Watertight Models. This track saw six registrations of which only three participants effectively sent the results of their runs.

Four experiments investigated whether and how interpolated faces cause impairment to memories for related target faces. Participants viewed target faces and then saw a presentation of interpolated faces that were related to some of the targets. Modified tests, which offered target and novel faces as recognition alternatives, detected impairment effects after short retention intervals but not af...
