An evaluation of the value of choice-making opportunities in single-operant arrangements: simple fixed- and progressive-ratio schedules

The current study compared the effects of choice and no-choice reinforcement conditions on the task responding of 3 children with autism across 2 single-operant paradigm reinforcer assessments. The first assessment employed simple fixed-ratio (FR) schedules; the second used progressive-ratio (PR) schedules. The latter assessment identified the differential strength of choice-making conditions in promoting task responding relative to no-choice conditions for 2 participants; no differential findings were obtained during the FR assessment.     

Religion and Bio-Psycho- Social Health: A Review and Conceptual Model

This paper presents a research-based conceptual model respectively linking three dimensions of religious experience (religious practices, spiritual beliefs, and faith community) with three dimensions of health (biological, psychological, and social). The model is used as a framework to highlight findings in the religion-health knowledge base and to provide a broad survey of this domain of inquiry. Considerations for future research on religion and health are addressed.     

A developmental perspective on bullying

In this paper, we examined the forms and relationship contexts of bullying in adolescence. Using cross‐sectional data, we assessed grade and sex differences in self‐reports of bullying and sexually harassing peers, as well as reports of dating aggression from1896 students from early to late adolescence. Reports of bullying others were highest around the school transition, with lowest levels at the end of high school. Boys reported more bullying and sexual harassment than girls. Sexual harassment of same‐ and opposite‐sex peers increased over the early adolescent years and leveled off in later high‐school years. There were no sex differences in the prevalence of indirect or physical aggression with a dating partner. Adolescents who bullied were at increased risk for the other forms of relationship aggression. These data highlight bullying as a relationship problem and point to the need for prevention programs to curtail the use of power and aggression in adolescent relationships. Aggr.

Implicit prejudice toward injecting drug users predicts intentions to change jobs among drug and alcohol nurses

The meaning and importance of implicit prejudice is a source of considerable debate. One way to advance this debate is to assess whether implicit prejudice can predict independent variance, beyond that predicted by explicit prejudice, in meaningful and unambiguous behaviors or behavioral intentions. In the current research, drug and alcohol nurses reported their level of stress working with injecting drug users, their job satisfaction, their explicit prejudice toward injecting drug users, and their intentions to leave drug and alcohol nursing. The nurses also completed the Single Category Implicit Association Test, which measured their implicit prejudice toward injecting drug users. Analyses revealed that implicit prejudice was a significant mediator, beyond explicit prejudice and job satisfaction, of the relation between job stress and intention to change jobs.     

Specificity of practice: interaction between concurrent sensory information and terminal feedback

In 2 experiments, the authors investigated a potential interaction involving the processing of concurrent feedback using design features from the specificity of practice literature and the processing of terminal feedback using a manipulation from the guidance hypothesis literature. In Experiment 1, participants produced (198 trials) flexion-extension movements to reproduce a specific pattern of displacement over time with or without vision of the limb position and with 100% or 33% knowledge of results (KR) frequency. The transfer test was performed without vision and KR. In Experiment 2, the authors assessed whether sensory information processing was modulated by the amount of practice. Participants performed 54 or 396 trials under a 100% or a 33% KR frequency with vision before being transferred to a no-vision condition without KR. Results of both experiments indicated that the Vision-33% condition suffered a larger detrimental effect of withdrawing visual information than the Vision-100% condition. Experiment 2 indicated that this detrimental effect increased with practice. These results indicated the reduction in terminal feedback prompted participants to more deeply process the concurrent visual information thus reinforcing their dependency on the visual information.     

A constructive approach to frustration in the practice of ministry

Conclusion The original frustration-aggression hypothesis was stated in very strong terms—every frustration produces an aggressive tendency and every aggression can be traced to a frustration. We know now that there can be other responses to frustration—aregression to childish behavior, apathetic withdrawal, or, even, quietly effectiveproblem-solving behavior. A person who learns how to use his frustration in problem-solving will not only be effective in his work, but will enjoy it.By organizing our time and planning our activities we eliminate those oppressing feelings of guilt, failure, and frustration. We are free to enjoy our work and play. Someone has said that the problem most people have is that they think about playing while working and think about working while playing, and do not do either one well. The minister who is thinking about a pastoral call while preparing his sermon or thinking about his sermon while visiting a parishioner does not do either one very well.A frustrated person cannot accomplish much because frustration blocks creativity, wastes time and energy as it divides the individual. To accept the challenge of dealing with frustration creatively is to make life a much more exciting and productive venture. It makes a minister an effective leader of people as he displays self-discipline, expresses concern, and shares the Gospel through the many activities of his life and church.     

Vocal reaction times to tachistoscopically presented high- and low-frequency verbs: some evidence for selective minor hemisphere linguistic analysis

The current study investigated the capacity of the right hemisphere to process verbs using a paradigm proven reliable for predicting differential, minor hemisphere lexical analysis in the normal, intact brain. Vocal reaction times of normal subjects were measured to unilaterally presented verbs of high and of low frequency. A significant interaction was noted between the stimulus items and visual fields. Post hoc tests showed that vocal reaction times to verbs of high frequency were significantly faster following right visual-field presentations (right hemisphere). No significant differences in vocal reaction time occurred between the two visual fields for the verbs of low frequency. Also, significant differences were observed between the two types of verbs following left visual-field presentation but not the right. These results were interpreted to suggest that right-hemispheric analysis was restricted to the verbs of high frequency in the presence of a dominant left hemisphere.     

Effects of auditory masking by white noise on variability of fundamental frequency during highly similar productions of spontaneous speech

Six adults (3 men, 3 women) produced highly similar spontaneous speech utterances during quiet and 90-dB SPL white noise. Although subjects' fundamental frequency (fo) was significantly increased when speaking in noise, their fo variability (coefficients of variation) throughout the utterance was not affected by the auditory disruption. This indicated that their ability to vary fo for linguistic stressing was preserved under short-term disturbed auditory feedback. These findings further supported the hypothesis that fo is under open-loop regulation.     

“No,You're Playing the Race Card”: Testing the Effects of Anti-Black,Anti-Latino,and Anti-Immigrant Appeals in the Post-Obama Era

Despite a sizable literature on racial priming, scholars have failed to account for the shifting nature of racial appeals. First, theories of racial priming have not yet been widely applied to increasingly common anti-immigrant and anti-Latino political appeals. Second, theories of racial priming have not adequately accounted for both an increasingly racialized political climate and increased tolerance for explicit anti-minority appeals. In two survey experiments fielded both before Trump's rise and after his presidential victory, we find the Implicit-Explicit (IE) model always fails for anti-black appeals, sometimes fails for anti-immigrant appeals, but consistently holds for anti-Latino appeals. While we find the null effects of implicit versus explicit anti-black and anti-immigrant appeals are partly driven by tolerance for the explicit appeals, we also find evidence that white Americans are adept at recognizing the racial content of appeals featuring widely used, congruent issue-group pairs. Our findings shed light on conditions under which the IE model does and does not hold in the current political era.
