Effects of a Peer Engagement Program on Socially Withdrawn Children with a History of Maltreatment

Children with a history of child maltreatment often have limited social interactions with other children and adults. This study examined the effects of a Peer Engagement Program, consisting of peer mentoring and social skills training with positive reinforcement, in three children with low levels of oral and social interaction. A multiple baseline, single-subject research design was used to test whether introduction of the intervention was associated with increased, directly observed oral interaction and engagement in social activities with peers and adults. The Child Behavior Checklist (CBCL) and the Social Skills Rating Scale (SSRS) were administered before and after intervention. All children showed increased levels of oral and social interaction and improved scores on the SSRS and the CBCL.     

How to blow the Whistle and still have a career afterwards

Filing charges of scientific misconduct can be a risky and dangerous endeavor. This article presents rules of conduct to follow when considering whether to report perceived misconduct, and a set of step-by-step procedures for responsible whistleblowing that describe how to do so once the decision to report misconduct has been made. This advice is framed within the university setting, and may not apply fully in industrial settings. Ms. Gunsalus, an attorney, has been responsible for a wide range of compliance issues and academic policy matters at her university including responding to allegations of scientific misconduct. She served on the United States Commission on Research Integrity and spent six years on the AAAS Committee on Scientific Freedom and Responsibility, four of them as chair. An earlier version of this paper was presented at the symposium entitled “Damned If You Do, Damned If You Don’t: What the Scientific Community Can Do About Whistleblowing” held during the Annual Meeting of the AAAS, Seattle, Washington, 15 February, 1997.     

2D location biases depth-from-disparity judgments but not vice versa

Visual cognition in our 3D world requires understanding how we accurately localize objects in 2D and depth, and what influence both types of location information have on visual processing. Spatial location is known to play a special role in visual processing, but most of these findings have focused on the special role of 2D location. One such phenomena is the spatial congruency bias, where 2D location biases judgments of object features but features do not bias location judgments. This paradigm has recently been used to compare different types of location information in terms of how much they bias different types of features. Here we used this paradigm to ask a related question: whether 2D and depth-from-disparity location bias localization judgments for each other. We found that presenting two objects in the same 2D location biased position-in-depth judgments, but presenting two objects at the same depth (disparity) did not bias 2D location judgments. We conclude that an object’s 2D location may be automatically incorporated into perception of its depth location, but not vice versa, which is consistent with a fundamentally special role for 2D location in visual processing.     

Binding object features to locations: Does the “spatial congruency bias” update with object movement?

One of the fundamental challenges of visual cognition is how our visual systems combine information about an object’s features with its spatial location. A recent phenomenon related to object–location binding, the “spatial congruency bias,” revealed that two objects are more likely to be perceived as having the same identity or features if they appear in the same spatial location, versus if the second object appears in a different location. The spatial congruency bias suggests that irrelevant location information is automatically encoded with and bound to other object properties, biasing perceptual judgments. Here we further explored this new phenomenon and its role in object–location binding by asking what happens when an object moves to a new location: Is the spatial congruency bias sensitive to spatiotemporal contiguity cues, or does it remain linked to the original object location? Across four experiments, we found that the spatial congruency bias remained strongly linked to the original object location. However, under certain circumstances—for instance, when the first object paused and remained visible for a brief time after the movement—the congruency bias was found at both the original location and the updated location. These data suggest that the spatial congruency bias is based more on low-level visual information than on spatiotemporal contiguity cues, and reflects a type of object–location binding that is primarily tied to the original object location and that may only update to the object’s new location if there is time for the features to be re-encoded and rebound following the movement.

Representational development of the human figure in familial retardates.

Representational development of the human figure of normal and familially retarded children was examined. Five tasks were employed: Drawing a Person, Figure Completion, two Form Puzzles, and Drawing on Dictation. Ss included 34 normal children, ages 3-0 to 5-10, and 34 familially retarded children, ages 4-4 to 13-1. The two groups were matched for mental age, socioeconomic status, public school attendance, and intact family structure. Results indicate that familial retardates performed as well as normals and at times surpassed them. Performance on these representational tasks is, predominantly, a function of mental age which lends support to a "developmental" theory of familial retardation and refutes the "defect" hypothesis.     

Eytan: The early development of a gifted child artist

The early graphic development of a precociously gifted child artist, Eytan, for whom a continuous record of drawings exists, is examined in the light of a set of theoretically‐based questions. These concern the course of graphic development, the role of perspective drawings, and the extent to which a precocious achievement of perspective drawing in childhood is a mark of pathology. The issue of giftedness as precocious development or as the mark of unique qualities, and the relationship between art and cognition are also considered.
