Noncontingent peer attention as treatment for disruptive classroom behavior

A functional analysis isolated peer attention as the primary maintaining variable for disruptive behavior displayed by a student with attention deficit hyperactivity disorder. Using a brief reversal design, noncontingent reinforcement was then shown to reduce disruptive behavior relative to the peer attention condition. Implications for assessing behavior disorders in mainstream school settings are discussed.     

Quantifying construct validity: two simple measures

Construct validity is one of the most central concepts in psychology. Researchers generally establish the construct validity of a measure by correlating it with a number of other measures and arguing from the pattern of correlations that the measure is associated with these variables in theoretically predictable ways. This article presents 2 simple metrics for quantifying construct validity that provide effect size estimates indicating the extent to which the observed pattem of correlations in a convergent-discriminant validity matrix matches the theoretically predicted pattern of correlations. Both measures, based on contrast analysis, provide simple estimates of validity that can be compared across studies, constructs, and measures meta-analytically, and can be implemented without the use of complex statistical procedures that may limit their accessibility.     

Self-awareness, deindividuation, and social identity: unraveling theoretical paradoxes by filling empirical lacunae

In an effort to examine paradoxes involving self-awareness, deindividuation, and social identity, this article reports the results of a study that examines the effects of a range of manipulation operationalizations of self and social identity on a complement of measurement operationalizations of self and social identity. Specifically, participants completed measures of self-awareness and ethnic social identity while confronted with their mirror image, while wearing a mask, or while exposed to a family tree delineating their ethnicity. Patterns of mean levels of self-awareness and ethnic social identity are used to examine the paradox of depersonalization and deindividuation, the paradox of (a)symmetrical activation of components of identity, and the paradox of deindividuation and the search for identity. Discussion considers the limitations of this approach and considers the implications of these results for the long-standing study of the interplay between self and social identity.

Development and Content Validity of the Participation and Sensory Environment Questionnaire

Qualitative methodology was used to develop items for a questionnaire designed to examine the perspectives of parents regarding the impact of the sensory environment on participation for children aged 3 to 5 who have autism spectrum disorders. A total of 34 parents/caregivers of children with autism spectrum disorders and 8 experts in autism spectrum disorders and/or measurement completed qualitative interviews for concept, content review, and cognitive interviewing. The result was a pool of 35 items for home/community domains for 3 scales. The outcome of this study was the development and content validation of the Participation and Sensory Environment Questionnaire.     

Shuffling your way out of change blindness

Change detection is typically discussed in the literature as a 2-state phenomenon. Small differences between otherwise identical images are easy to detect when the images are superimposed in space and alternated in time (“shuffled”). However, change blindness results from any disruption that prevents the critical change from generating the sole salient transient. Here we show that different presentation strategies produce different degrees of change blindness for the same change. Specifically, shuffling the images supports faster change detection than viewing the same 2 images side by side, even when the images contain a number of distracting differences. In Experiment 1, pairs of photographs having a 50 % chance of containing a difference were viewed either in alternation, in a “Shuffle” condition, or simultaneously, in a “Side-by-Side” condition. Change detection was about 6 seconds faster when the images were viewed in the “Shuffle” mode. In Experiment 2, we presented two images that were slightly laterally shifted relative to each other (0–48 pixels). The RT benefit for the Shuffle viewing mode was very strong when the relative shift was small, to insignificant when there was a large difference between the two images. However, at large shifts, Shuffle maintained an accuracy advantage. It seems that changes are easier to detect when comparing images in a Shuffle condition rather than Side-by-Side. This has important implications for real world tasks like radiology where detection of change is critical.     

Lifting the curtain on the Wizard of Oz: biased voice-based impressions of speaker size

The consistent, but often wrong, impressions people form of the size of unseen speakers are not random but rather point to a consistent misattribution bias, one that the advertising, broadcasting, and entertainment industries also routinely exploit. The authors report 3 experiments examining the perceptual basis of this bias. The results indicate that, under controlled experimental conditions, listeners can make relative size distinctions between male speakers using reliable cues carried in voice formant frequencies (resonant frequencies, or timbre) but that this ability can be perturbed by discordant voice fundamental frequency (F-sub-0, or pitch) differences between speakers. The authors introduce 3 accounts for the perceptual pull that voice F-sub-0 can exert on our routine (mis)attributions of speaker size and consider the role that voice F-sub-0 plays in additional voice-based attributions that may or may not be reliable but that have clear size connotations.     

Group membership,group norms,empathy, and young children's intentions to aggress

This study assessed the effect of ingroup norms and empathy on 6 and 9‐year‐old children's (N=161) attitudes and aggressive intentions toward outgroup members. Prior to an intergroup drawing competition against an outgroup, participants' empathy was measured, and they were randomly assigned to a simulated group with a norm of direct or indirect aggression, or no aggression norm. Results indicated participants' attitudes were less positive toward the outgroup vs. the ingroup, and that both direct and indirect aggressive intentions were displayed toward the outgroup. Most importantly, the ingroup was liked less when it had an aggression norm, and the participants' aggressive intentions were not enhanced by the group aggression norm. Empathy was a significant negative predictor of direct but not indirect aggression intentions. Implications for understanding the instigation and inhibition of children's aggression intentions are discussed. Aggr. Behav. 35:244–258, 2009. © 2009 Wiley‐Liss, Inc.
