The nature of adaptation in distance perception based on oculomotor cues

In previous work by the senior authors, brief adaptation to glasses that changed the accommodation and convergence with which objects were seen resulted in large alterations in size perception. Here, two further effects of such adaptation are reported: alterations in stereoscopic depth perception and a change when distance is represented by a response of S’s arm. We believe that the three effects are manifestations of one primary effect, an alteration of the relation between accommodation and convergence on the one hand and the distance they represent in the nervous system (registered distance) on the other. This view was supported by the results of two experiments, each of which demonstrated that the alterations in stereoscopic depth perception could be obtained after adaptation periods which had provided no opportunity to use stereoscopic vision, and that the adaptation effect was larger for depth perception than for size perception when it was obtained under the same conditions; the latter finding was expected if both effects resulted from the same change in registered distance. In three of the five experiments here reported, the variety of cues that could represent veridical distance during the adaptation period was limited. In one condition of adaptation, only the pattern of growth of the retinal images of objects that S approached and the kinesthetic cues for S’s locomotion served as cues to veridical distance. In two other conditions S remained immobile. In one of these, only the perspective distortion in the projection of the scene that S viewed mediated veridical distance, and in the other one familiar objects of normal size were successively illuminated in an otherwise totally dark field, conditions from which opportunities to use stereoscopic vision were again absent. After exposure to each of these adaptation conditions, adaptive changes in perceived size and larger ones in perceived stereoscopic depth were obtained. Because we found that familiar size may serve as the sole indicator of veridical distance in an adaptation process, we concluded that it can function as a perceptual as distinguished from an inferential cue to distance.     

The sources of developmental differences in children's incidental processing during discrimination trials

Crane and Ross reported that second graders learned more than sixth graders about attributes made relevant after solution of a discrimination task. Here two experiments are reported that enlighten the sources of this developmental difference. Both make use of an experimental technique whereby children verbalize their hypotheses during solution of a discrimination problem. The results indicate that ten-year-olds do not learn about incidental attributes that they tested while irrelevant in the pre-solution period, but that five-year-olds and seven-year-olds do. Children of all three ages process incidental information about attributes that they did not sample pre-solution. With some qualification, the incidentally processed information is retained throughout a five-minute delay interval. The results bear on developmental trends in the distribution of attention and on theoretical accounts of incidental learning in discrimination tasks.     

The Lived Experiences of Addiction Counselors After Marijuana Legalization

This qualitative study examines the perceptions of counselors who work with populations with addictions in states where marijuana has been legalized. Findings include themes related to client experiences, counselor experiences, specific interventions, and lack of understanding.     

A Preliminary Longitudinal Study of Multicultural Competence in Counselor Education

The purpose of this study was to investigate longitudinal changes in master’s-level counselor trainees’ (N = 78) self-perceptions of their multicultural counseling competence over the course of their counseling program. Multilevel modeling results indicated an increase in scores across 3 time points. The authors discuss study limitations and how counselors and counselor educators can incorporate the study’s findings into their practice and into the education and supervision of counselor trainees.     

"Saying one thing and doing another": examining the impact of event order on hypocrisy judgments of others

This study investigated whether the temporal order of people's expressed statements and their behaviors affected others' judgments of hypocrisy, and why. It was proposed that hypocrisy would be greater when a statement establishing a personal standard preceded a behavior violating that standard as opposed to the reverse order. This order effect occurred in three studies, generalizing across two topic areas (healthy living and safe sex) and for both normative and non-normative statements (pro/anti-safe sex). Mediation analyses indicated that the reverse order mitigated against hypocrisy because the target's inconsistency was attributed to dispositional change. The discussion addresses additional variables likely to affect hypocrisy and the relationship of this research to hypocrisy paradigms in dissonance.     

Contextual moderation of racial bias: the impact of social roles on controlled and automatically activated attitudes

Three experiments tested the hypothesis that the social roles implied by specific contexts can attenuate or reverse the typical pattern of racial bias obtained on both controlled and automatic evaluation measures. Study 1 assessed evaluations of Black and Asian faces in contexts related to athlete or student roles. Study 2 compared evaluations of Black and White faces in 3 role-related contexts (prisoner, churchgoer, and factory worker). Study 3 manipulated role cues (lawyer or prisoner) within the same prison context. All 3 studies produced significant reversals of racial bias as a function of implied role on measures of both controlled and automatic evaluation. These results support the interpretation that differential evaluations based on Race x Role interactions provide one way that context can moderate both controlled and automatic racial bias.     

Measuring "negative body image": validation of the Body Image Disturbance Questionnaire in a nonclinical population

Despite numerous measures of facets of the body image construct, no single assessment broadly measures a continuum of body image disturbance. Accordingly, this study developed the Body Image Disturbance Questionnaire (BIDQ), derived from the Body Dysmorphic Disorder Questionnaire. Participants were 220 college women and 75 college men who completed an online survey containing this new assessment and established measures of body image and psychosocial functioning. Results confirmed that the Body Image Disturbance Questionnaire was internally consistent and free of impression-management response bias. For both sexes, the measure converged appropriately with other body image indices (evaluation, affect, investment, and impact), was positively correlated with depression, social anxiety, and eating disturbance. Scores on this assessment also predicted psychosocial functioning above and beyond body dissatisfaction as a predictor. Greater body image disturbance was observed among women than men, among heavier than lighter women, and among White than African American women. Limitations and future research implications are discussed.     

Exploring actor-partner interdependence in family therapy: whose view (parent or adolescent) best predicts treatment progress?

Predictions of family therapy outcome consistently vary depending on which client rates the alliance. We used the actor-partner interdependence model (Kenny, Kashy, & Cook, 2006) to test the interdependence of parents' and adolescents' ratings of alliance, session depth/value, and improvement-so-far after Sessions 3, 6, and 9. Initial analyses found trivial between-therapists variance; therefore, a 3-level hierarchical model partitioned the variance in these variables into between families, between family members, and between session components. For alliance and session depth, results showed a significant parent actor effect and a significant adolescent partner effect. Specifically, when parents saw a stronger alliance, they also saw the session as more valuable, but when adolescents saw a stronger alliance, their parents saw the session as less valuable. Both the parents' and the adolescents' improvement scores showed significant linear growth over time, and adolescents' alliance ratings were positively associated with their own and their parents' views of therapeutic progress.     

Adjunctive mirror exposure for eating disorders: A randomized controlled pilot study

Mirror exposure therapy has proven efficacious in improving body image among individuals with shape/weight concerns and eating disorders. No randomized controlled trials have examined the effect of mirror exposure in a healthy-weight clinical sample of eating disordered individuals. The purpose of the current study was to test the efficacy of a five-session acceptance based mirror exposure therapy (A-MET) versus a non directive body image therapy (ND) control as an adjunctive treatment to outpatient eating disorder treatment. Thirty-three males and females aged 14–65 with a body mass index of 18.5–29.9 were randomized to five sessions of A-MET or ND with a 1-month follow-up. Results indicated large to moderate effect size differences for efficacy of A-MET across measures of body checking, body image dissatisfaction, and eating disorder symptoms (d = ?0.38 to ?1.61) at end of treatment and follow-up. Baseline measures of social comparison and history of appearance-related teasing were predictive of treatment response. There were also differential effects of treatment on participants' perceived homework quality, but no differences in therapeutic alliance. Results suggest that A-MET is a promising adjunctive treatment for residual body image disturbance among normal and overweight individuals undergoing treatment for an eating disorder. Future research and clinical implications are discussed.
