Perceived fit with an academic environment: Attitudinal and behavioral outcomes

Because person–organization fit relates to important outcomes, and because fit is a time-dependent process, there exists a need to model longitudinal data related to fit. In a multi-university sample (N = 1174), we tested hypotheses concerning person–organization fit and various behavioral and attitudinal outcomes; correlations between changes in these variables over time, and the correlates of these changes. Using autoregressive modeling and latent growth curve modeling, results indicated that academic fit leads to academic satisfaction, which in turn leads to turnover intent, and to a lesser extent GPA and class absenteeism. Changes in academic fit correlated highly with similar changes in satisfaction and GPA and with opposite changes in turnover intent. Academic satisfaction did not correlate with subsequent organizational citizenship behavior (OCB) as predicted; changes across these domains were significantly related, but were small. Consistent with our hypotheses, Realistic interests correlated negatively with changes in academic fit and satisfaction. Investigative interests were correlated positively with changes in fit and initial satisfaction levels. We conclude by discussing implications, limitations, and future research concerning the longitudinal analysis of person–organization fit.     

A practical variation of a multiple-schedule procedure: brief schedule-correlated stimuli

Multiple schedules using continuous discriminative stimuli have been used to minimize children's disruptive requesting for teacher attention (e.g., colored floral leis; Tiger & Hanley, 2004; Tiger, Hanley, & Heal, 2006). The present study evaluated the effectiveness of, and children's preferences for, two multiple-schedule arrangements in which brief experimenter vocalizations served as discriminative stimuli. Results showed that brief signals were highly effective discriminative stimuli for 3 of the 4 children, and that all children preferred one or both variations of the multiple schedule to a control arrangement. For 1 child, highly discriminated responding was achieved only when continuous signals were introduced.     

Can fixed views of ability boost performance in the context of favorable stereotypes?

Prior research has demonstrated that stereotypes affect negatively stereotyped groups in part through the implied immutability of group members’ abilities. Accordingly, a belief that ability is malleable through effort and hard work has been shown to boost the performance of negatively stereotyped groups. We predicted, however, that among favorably stereotyped groups, a belief that ability is fixed would reinforce the immutability of the group differences upon which stereotype-induced social comparisons are made [Walton, G. M., & Cohen, G. L. (2003). Stereotype lift. Journal of Experimental Social Psychology, 39, 456–467] and result in enhanced performance. We found experimental support for these predictions in two favorably stereotyped groups in math: Asians (Study 1) and men (Study 2). Perceived difficulty of the math test helped explain the performance effects in Study 2. Implications of schooling emphasizing innate ability for exacerbating achievement gaps are discussed.     

A large scale study of the assessment of the social environment of middle and secondary schools: The validity and utility of teachers' ratings of school climate, cultural pluralism, and safety problems for understanding school effects and school improvement

Due to changes in state and federal policies, as well as logistical and fiscal limitations, researchers must increasingly rely on teachers' reports of school climate dimensions in order to investigate the developmental impact of these dimensions, and to evaluate efforts to enhance the impact of school environments on the development of young adolescents. Teachers' climate ratings exhibited a robust dimensional structure, high levels of internal consistency, and moderate levels of stability over 1-and 2-year time spans. Teachers' climate ratings were also found to be related consistently with students' ratings. In three large-scale samples of schools, teachers' climate ratings were associated significantly and consistently with students' performance on standardized tests of academic achievement, and with indexes of their academic, behavioral, and socio-emotional adjustment.     

Children with Autism and Their Friends: A Multidimensional Study of Friendship in High-Functioning Autism Spectrum Disorder

This study of Israeli and American preadolescent children examined characteristics of friendship in 44 children with high-functioning autism spectrum disorder (HFASD) compared to 38 typically developing children (TYP), as they interacted with a close friend Participants were 8-12 years of age (HFASD: Israel, n = 24; USA, n = 20; TYP: Israel, n = 23; USA, n = 15), and were matched on SES, receptive language vocabulary, child age, and gender (each study group included one girl). Multidimensional assessments included: individual behaviors of target children and observed child-friend interactions during construction and drawing scenarios; target child's and friend's self-perceived mutual friendship qualities; and mother-reported characteristics (friendship's duration/frequency; friend's age/gender/disability status). Overall, children with HFASD displayed a number of differences on individual and dyadic friendship measures. Both age and verbal abilities affected friendship behaviors. Children with HFASD and their friends perceived friendship qualities similarly, suggesting that preadolescents with HFASD have capacities for interpersonal awareness. Between-group similarities also emerged on several complex social behaviors, suggesting that friendship follows a developmental trajectory in autism and may enhance social interaction skills in autism.     

Cognitive ability, personality, and academic performance in adolescence

Does positive thinking predict variance in school grades over and above that predicted by cognitive ability? Six hundred and thirty nine high school students participated in a three-year longitudinal study that predicted grades using cognitive ability and three positive thinking variables – self-esteem, hope, and attributional style. Hope, positive attributional style and cognitive ability predicted higher grades, whilst self-esteem was a less consistent predictor of academic performance. Structural equation modelling revealed significant paths from cognitive ability, gender, and a second order positive thinking factor to grades. The results suggest that intelligence, gender, and positive thinking each play a unique role in predicting academic performance in youth. Some suggestions for further research are made.     

Emotional Problems Suppress Disorder/Performance Associations in Adult ADHD Assessment

Issues related to Attention Deficit Hyperactivity Disorder (ADHD) are commonly assessed using a combination of indicators, including patient report and performance on cognitive tasks. The current study investigates the potential that emotional problems may suppress the relationship between objective continuous performance test (CPT) results and ADHD symptoms in a sample of 53 young adults referred to an outpatient clinic for cognitive evaluations, 26 of whom met diagnostic criteria for ADHD. Data indicate that emotional problems and continuous performance represent unique elements of adult ADHD, whether assessed via interview or self-report. Results also indicate that emotional problems do suppress CPT–ADHD relations, suggesting that failure to control for emotional problems may account, in part, for modest associations in the literature between CPT performance and other indicators of ADHD.     

The roles of ethnic identity,anti-white attitudes,and academic self-concept in African American student achievement

Conventional wisdom in much of the educational and psychological literatures states that the ethnic and racial identity of African American students is related to their academic achievement. The purpose of this study was to determine whether ethnic identity and anti-white attitudes predicted the academic achievement of African American students at a historically Black university. A hypothesized path model was proposed that included ethnic identity, attitudes toward other ethnic groups, anti-white attitudes, perceptions of caring faculty, academic self-concept, and devaluing academic success. The path analysis model explained 27% of the variance in grade point average and revealed three direct effects on grade point average: (a) academic self-concept (positive), (b) devaluing academic success (negative), and (c) anti-white attitudes (negative). Ethnic identity was indirectly linked with grade point average (GPA) through academic self-concept and devaluing academic success. Tests of two alternative nested models suggest that even in an indirect role, ethnic identity may be more important than anti-white attitudes in a model of African American academic achievement.
