A Comparison of Two Group Contingencies on Teachers’ Use of Behavior-Specific Praise

The present study evaluated the effects of two reinforcement contingencies on teacher use of behavior-specific praise (BSP) in the classroom. An alternating treatments design was used to compare the implementation of both an independent and interdependent contingency to increase frequency of BSP delivery. Four general education elementary school teachers and their students participated. Teachers’ use of BSP and general praise, as well as, behavior-specific and general reprimands were evaluated. Data were also collected on students’ levels of academically engaged and disruptive behaviors. Both the independent and interdependent conditions resulted in higher frequencies of BSP and reduced the use of both general and behavior-specific reprimands. Student levels of academic engagement increased while disruption decreased across both contingencies. Results of the present study are discussed in terms of related literature and implications for applied practice.

     

The processing of consonants and vowels in reading: evidence from the fast priming paradigm

We assessed the early encoding of consonant and vowel information in the reading of English, using the fast priming paradigm. With 30-msec prime durations, gaze durations on target words were shorter when preceded by high-frequency consonant-same primes (which shared consonant information with the target word; e.g., lake-like) than when preceded by vowel-same primes (which shared vowel information with the target word; e.g., line-like), but there were no priming effects for low-frequency primes. With 45-msec prime durations, however, there was no effect of prime frequency and gaze durations on target words were shortened equally when they were preceded by consonant-same primes and vowelsame primes, as compared with control primes (e.g., late-like). The results suggest that the processing of consonants is more rapid than that of vowels, providing further evidence for the distinction between consonant and vowel processing in the reading of English.     

Relations Between Continuous Performance Test Performance Measures and ADHD Behaviors

The Conners' Continuous Performance Test (CPT) is a neuropsychological task that has repeatedly been shown to differentiate ADHD from normal groups. Several variables may be derived from the Conners' CPT including errors of omission and commission, mean hit reaction time(RT), mean hit RT standard error, d', and . What each CPT parameter actually assesses has largely been based upon clinical assumptions and the face validity of each measure (e.g., omission errors measure inattention, commission errors measure impulsivity). This study attempts to examine relations between various CPT variables and phenotypic behaviors so as to better understand the various CPT variables. An epidemiological sample of 817 children was administered the Conners' CPT. Diagnostic interviews were conducted with parents to determine ADHD symptom profiles for all children. Children diagnosed with ADHD had more variable RTs, made more errors of commission and omission, and demonstrated poorer perceptual sensitivity than nondiagnosed children. Regarding specific symptoms, generalized estimating equations (GEE) and ANCOVAs were conducted to determine specific relationships between the 18 DSM-IV ADHD symptoms and 6 CPT parameters. CPT performance measures demonstrated significant relationships to ADHD symptoms but did not demonstrate symptom domain specificity according to a priori assumptions. Overall performance on the two signal detection measures, d' and , was highly related to all ADHD symptoms across symptom domains. Further, increased variability in RTs over time was related to most ADHD symptoms. Finally, it appears that at least 1 CPT variable, mean hit RT, is minimally related to ADHD symptoms as a whole, but does demonstrate some specificity in its link with symptoms of hyperactivity.     

Another look at semantic priming without awareness

In a recent study, McCauley, Parmelee, Sperber, and Carr (1980) reported results indicating that semantic priming had been produced by visual stimuli that were backward masked at durations too brief for greater than chance report. The conclusions drawn from such an experiment are critically dependent upon whether or not the primes were actually masked below the thresh-old for identification during priming trials. The three experiments reported here provide evidence that this requirement was not met. Rather, McCauley et al.’s (1980) methodology allowed for an uncontrolled increase in light adaptation during the actual testing of prime efficacy in the priming session. This increase in light adaptation reduced the effectiveness of the backward mask and resulted in an increase in prime visibility during priming trials. Thus, semantic priming probably occurred under conditions in which commensurate visual information was actually available.     

Examination of gaze behaviors under in situ and video simulation task constraints reveals differences in information pickup for perception and action

Queensland University of Technology, Brisbane, Queensland, Australia Gaze and movement behaviors of association football goalkeepers were compared under two video simulation conditions (i.e., verbal and joystick movement responses) and three in situ conditions (i.e., verbal, simplified body movement, and interceptive response). The results showed that the goalkeepers spent more time fixating on information from the penalty kick taker’s movements than ball location for all perceptual judgment conditions involving limited movement (i.e., verbal responses, joystick movement, and simplified body movement). In contrast, an equivalent amount of time was spent fixating on the penalty taker’s relative motions and the ball location for the in situ interception condition, which required the goalkeepers to attempt to make penalty saves. The data suggest that gaze and movement behaviors function differently, depending on the experimental task constraints selected for empirical investigations. These findings highlight the need for research on perceptual— motor behaviors to be conducted in representative experimental conditions to allow appropriate generalization of conclusions to performance environments.     

Antecedents and trajectories of achievement goals: A self‐determination theory perspective

Background. Research has shown that both achievement goal theory and self‐determination theory (SDT) are quite useful in explaining student motivation and success in academic contexts. However, little is known about how the two theories relate to each other. Aim. The current research used SDT as a framework to understand why students enter classes with particular achievement goal profiles, and also, how those profiles may change over time. Sample. One hundred and eighty‐four undergraduate preservice teachers in a required domain course agreed to participate in the study. Method. Data were collected at three time points during the semester, and both path modelling and multi‐level longitudinal modelling techniques were used. Results. Path modelling techniques with 169 students, results indicated that students' autonomy and relatedness need satisfaction in life predict their initial self‐determined class motivation, which in turn predicts initial mastery‐approach and ‐avoidance goals. Multi‐level longitudinal modelling with 108 students found that perceived teacher autonomy support buffered against the general decline in students' mastery‐approach goals over the course of the semester. Conclusions. Data provide a promising integration of SDT and achievement goal theory, posing a host of potentially fruitful future research questions regarding goal adoption and trajectories.     

Normative MMPI-2 Profiles of Christian Counseling Students: An Investigation of Subculture in Standardized Testing

This research sought to explore whether a normative profile on the MMPI-2 emerged for counseling students in a counselor training program at a seminary in the Midwest and the extent to which this profile compares to those proposed for counseling students or those preparing for pastoral ministry. Normative profiles of master’s level counseling students were compared to profiles of similar samples. Findings indicated that profiles of the current student sample are similar to those of other religious students. Implications of these findings are explored regarding the use of the MMPI-2 with counseling students who are members of the Christian subculture.
