Seven experiments involving a total of 203 college students explored a form of object-specific priming and established a robust object-specific benefit that indicates that a new stimulus will be named faster if it physically matches a previous stimulus seen as part of the same perceptual object. (SLD)

Proposes a framework to examine principals' careers and argues for more research attention on that subject. The framework facilitates understanding of the principalship incentive system by showing how objective features of the principal's role and the principal's own assessment of the career are intertwined. Principals' accounts of their careers…

Examined the learning of a manipulative response by well and at-risk infants of 6 to 13 months of age who had experienced respiratory interventions in the perinatal period. Risk status reliably predicted the learning performance. Results confirmed that the effects of perinatal interventions involving respiratory complications influenced infants'…

Sixty-four infants viewed side-by-side videotapes of toy trains (in four visual conditions) and listened to sounds at increasing or decreasing amplitude designed to match one of the videos. Results suggested that five-month olds were sensitive to auditory-visual distance relations and that change in size was an important visual depth cue. (MDM)

Presents three student exercises that demonstrate common perceptual errors described in social psychological literature: actor-observer effect, false consensus bias, and priming effects. Describes methods to be followed and gives terms, sentences, and a story to be used in the exercises. Suggests discussion of the bases and impact of such…

To assess the effects of individual attentional focus differences on measures of mental skills, distractibility was studied for 272 first- and second-year college undergraduates through a speeded visual search task and tests of mental and verbal ability. Results suggest that perceptual/attentional factors are an important aspect of measured…

Provides clear definitions of administrator and counselor roles in the interest of school effectiveness. Although guiding a school to instructional excellence is the most important administrative task, counselors have only limited curricular responsibility. Shared roles include the areas of public relations, drug abuse education, and knowledge of…

This study, involving 15 older adults with hearing impairments, investigated the relationship between sentence recognition ability and two types of signal processing in hearing aids. Results indicated a significant improvement in sentence recognition when employing an instrument with adaptive compression versus an instrument with an adaptive…

Describes a perceptual illusion, the Janus mask, for use in introductory psychology demonstrations. Suggests using a motor or videotaped image to rotate the mask, giving the impression that the mask is following a moving observer or oscillating. Recommends the illusion to show that perception is usefully conceptualized as hypothesis testing. (DK)

Investigated 4-6 year olds' ability to compare the distances covered by a direct and an indirect route to a location. Although many children believed that both routes covered the same distance, about 40% of the four year olds could explain why the direct route was shorter. (MDM)

Summarizes two Israeli case studies concerning an internal curriculum coordinator functioning as a school staff member and an external curriculum coordinator delegated by a national project. The schools had similar (participative) educational philosophies. Studies highlighted the principal-coordinator relationship, personal factors affecting the…

Before "unstructuring" or "restructuring," a school or district or state should think first about students, adopt successful learning as the criterion for judging the appropriateness of all daily activities, expect all adults to be successful learners, and identify the rules, roles, and relationships (the social structure) needed to support…

Effective principals pay close attention to body language and other subtle actions that are constantly read and interpreted by staff and students. Principals must not only talk the talk of an instructional leader but also walk the walk of a committed instructional leader. Specific suggestions are provided. (MLH)

This study examined the impact of maternal labeling of children as gifted on the sibling relationship in 144 pairs of firstborn and secondborn siblings classified as both gifted, firstborn gifted, secondborn gifted, or neither gifted. Five aspects of the sibling relationship were examined: warmth/closeness, status/power, conflict, maternal…

Used data from infants in operant head-turning procedure to examine effects of structure and redundancy of speech context on discovery of two target syllables. Clustering strategy, which presupposes basic element of perception and aggregates these elements to form units, may complement bracketing strategy, which presupposes endpoint cues and…
