Effects of Self-Monitoring on On-Task Behaviors of At-Risk Middle School Students

The purposes of this study were to evaluate the effects of self-monitoring on increasing the on-task behaviors of four at-risk middle school students, and to examine its indirect effects on academic performance. Additionally, we attempted to develop and validate cost- and time-efficient procedures that typical classroom teachers could use. The data from a multiple baseline design across three academic settings, replicated with four students, revealed immediate increases in on-task behavior as each student began to self-monitor in each sequential setting. The data also revealed slightly higher levels of academic performance and, in most instances, gradually accelerating trends. These findings suggest that self-monitoring is a cost- and time-efficient procedure that classroom teachers can use to teach at-risk students to manage their own behaviors.     

Considering prior knowledge when using elaborative interrogation

Previous studies have promoted the use of elaborative interrogation (a “why”-questioning strategy) for the acquisition of factual information. One assumption in these studies is that prior knowledge influences when students will be able to use the strategy, with greater prior knowledge leading to higher recall performance. In the studies reviewed here, the effect of prior knowledge on strategy effectiveness was investigated. Specifically, students' performances were compared for materials about which they possessed substantial prior knowledge, little prior knowledge, inconsistent prior knowledge, or shared prior knowledge. In general, the data support the use of elaborative interrogation when studying alone or in dyads especially when learners possess some relevant prior knowledge about the new information.     

RECONFIRMATION OF THE SHORT-TERM STORAGE CONCEPT

Abstract— Recent research questions the existence of a short-term storage mechanism capable of holding limited information temporarily Specifically, serial-recall results with a through-list distractor (TLD) procedure, in which a distracting task is interposed between list Items as well as between the list and recall period, generally resemble the results of immediate-recall procedures The present study, however, reconfirms the utility of short-term storage by demonstrating an important difference between immediate and TLD recall A word-length effect, or advantage for lists of shorter words (which minimize short-term forgetting during spoken recall), did not occur with a TLD procedure.     

An electrophysiological model of human visual reaction time

Human visual reaction times were fractionated into component latencies measuring visual reception time, opto-motor integration time, central motor outflow time, and peripheral motor time on the basis of evoked cortical activity recorded from the intact scalp and the occurrence of the response electromyogram. Normative data are presented for a right-foot dorsiflexion task studied on 18 male subjects, together with an analysis of inter- and intra-subject variability in response timing. Faster reactors were found to display briefer opto-motor integration times and motor times, while an individual's faster responses were characterized by shorter motor outflow times and motor time. These results are interpreted in terms of varying physiological mechanisms.     

Factors Influencing Gay Men's Attitudes,Subjective Norms,and Intentions With Respect to Performing Sexual Behaviors1

In a recent paper (Fishbein et al., 1992) gay men's attitudes and subjective norms were found to be accurate predictors of their intentions to perform a variety of sexual behaviors. In addition, the relative importance of norms as determinants of intention was found to be greater in Seattle (a city with a well organized gay community) than in Albany (a city in which the gay community is not well organized). The purpose of the present study was to investigate the extent to which the men's attitudes, subjective norms, and intentions were influenced by a number of situational and individual difference variables. Three hundred and fourteen self-identified gay or bisexual men from Seattle (134), Denver (78), and Albany (102) completed a questionnaire specifically designed for this study. As expected, type of partner and type of sexual activity significantly influenced attitudes, perceived norms, and intentions. In addition, these dependent variables were also influenced, in part, by city of residence, age, and perceived risk of HIV infection. The findings provide additional justification for developing different interventions for gay men in different cities, age, and perceived risk groups.     

Goal setting and the differential influence of self-regulatory processes on complex decision-making performance

The effects of goal setting and cognitive self-regulatory processes were examined on a highly complex task, a managerial decision-making simulation. It was hypothesized that the presence vs. absence of a specific performance goal would moderate the strength of relations between performance and 2 self-regulatory processes: self-efficacy judgments and self-evaluative reactions. Ss received either a moderately or extremely difficult task goal, or no specific goal. Self-regulatory processes were assessed after an initial trial block. Regression analyses revealed that, as predicted, both self-regulatory processes more strongly affected performance when Ss received a specific goal. Contrary to earlier findings obtained with simple activities, dissatisfaction with prior outcomes impaired performance. Ss who were dissatisfied with past attainments exerted much decision effort but adopted inferior task strategies that produced poorer results.     

Confirmation of linear system theory prediction: Changes in Herrnstein's k as a function of changes in reinforcer magnitude

Eight human subjects pressed a lever on a range of variable-interval schedules for 0.25¢ to 35.0¢ per reinforcement. Herrnstein's hyperbola described seven of the eight subjects' response-rate data well. For all subjects, the y-asymptote of the hyperbola increased with increasing reinforcer magnitude and its reciprocal was a linear function of the reciprocal of reinforcer magnitude. These results confirm predictions made by linear system theory; they contradict formal properties of Herrnstein's account and of six other mathematical accounts of single-alternative responding.
