The Inclusion House: Where Pastors Learn to Minister to Individuals with Disabilities

The Inclusion House is a unique dorm in Holland, Michigan, where nondisabled students, studying to be leaders in the faith community as future pastors, live side-by-side same-aged individuals with intellectual disabilities. After one year, a qualitative study using semi-structured interviews was conducted with the nondisabled roommates. Findings showed overall positive feelings involving watching roommates with a disability become more independent, learning to balance roles as a friend vs. helper, as well as knowledge gleaned about working with these type of individuals as well as their families for their future occupations. These findings are important for the education of future leaders of the church and the manner by which they can include people with disabilities and their families in faith communities.     

Chickadees discriminate contingency reversals presented consistently,but not frequently

Chickadees are high-metabolism, non-migratory birds, and thus an especially interesting model for studying how animals follow patterns of food availability over time. Here, we studied whether black-capped chickadees (Poecile atricapillus) could learn to reverse their behavior and/or to anticipate changes in reinforcement when the reinforcer contingencies for each stimulus were not stably fixed in time. In Experiment 1, we examined the responses of chickadees on an auditory go/no-go task, with constant reversals in reinforcement contingencies every 120 trials across daily testing intervals. Chickadees did not produce above-chance discrimination; however, when trained with a procedure that only reversed after successful discrimination, chickadees were able to discriminate and reverse their behavior successfully. In Experiment 2, we examined the responses of chickadees when reversals were structured to occur at the same time once per day, and chickadees were again able to discriminate and reverse their behavior over time, though they showed no reliable evidence of reversal anticipation. The frequency of reversals throughout the day thus appears to be an important determinant for these animals’ performance in reversal procedures.     

See the Triumph Healing Arts Workshops for Survivors of Intimate Partner Violence and Sexual Assault

Existing research demonstrates the potential value of arts-based interventions for survivors of abuse and other forms of trauma. The See the Triumph Healing Arts Workshops were designed to provide survivors of intimate partner violence and sexual assault with an opportunity to express themselves and connect with others through arts-based interventions. When appropriate, using the art developed through the workshops to create an art exhibit can be useful for raising awareness and giving voice to survivors in the local community. The preliminary results of the pilot evaluation suggest that the workshops were well-received and allowed participants to experience emotional expression, connection with others, and greater self-awareness.     

Does Repeated Exposure to Popular Media Strengthen Moral Intuitions?: Exploratory Evidence Regarding Consistent and Conflicted Moral Content

Previous studies have indicated that media consumption may influence moral intuition sensitivity. The present exploratory studies sought to expand on these findings by employing a three-phase, longitudinal experiment conducted over nine weeks, where participants were exposed to two genres of films (romance, action) mixed in various ratios (high = 100% romance, medium = 60% romance, low = 20% romance, none = 0% romance). Findings from the initial study indicate that repeated exposure to romantic films led to increases in sensitivity for four of the five moral intuitions (i.e., care, fairness, authority, purity); at the same time, any exposure to action films seemed to erode these changes. A follow-up post-hoc content analysis sought to confirm these findings and test an operationalization of “moral conditioning.” We discuss the results in regards to media entertainment theory and research, and the societal implications of the role of media entertainment to reinforce standards of moral judgment.     

Pace alteration and estimation of time intervals

This experiment examined the effects on participants' estimates of interval duration of altering the pace of auditory stimuli contained within "filled" intervals. Because most previous studies on the filled interval effect have utilized visual displays, auditory stimuli were used to assess whether the effect would be present. In addition, previous studies compared two intervals, one of which was filled and the other unfilled. In the present study, both intervals were filled with tones at one of three rates (or "paces"): slow, medium, or fast. 25 participants (20 women) ages 18 to 29 years (M = 20.4, SD = 2.3) were recruited from psychology courses and programs. Participants first heard a "training" interval filled with tones at one of the three paces and then attempted to reproduce the duration of that training interval in the "test" interval. The pace of stimuli in each pair of training and test intervals was varied so participants received all possible combinations of paces of auditory stimuli during the training and test trial sets. Analysis showed that, when training pace was fast and test pace was medium or slow, participants' estimates were longer than the actual test interval durations. Conversely, when training pace was slow and test pace was medium or fast, participants' estimates were shorter than actual test interval durations. In addition, when judging shorter intervals, participants estimated more time had passed than actually had, while they estimated that less time had passed than actually had for longer intervals, thus providing support for Vierordt's law.     

Tufted capuchins (<Emphasis Type="Italic">Cebus apella</Emphasis>) attribute value to foods and tools during voluntary exchanges with humans

This research examined exchange and value attribution in tufted capuchin monkeys (Cebus apella). We presented subjects with opportunities to obtain various foods and a tool from an experimenter in exchange for the foods or tool in the subjects' possession. The times elapsed before the first chow biscuits were expelled and/or an exchange took place were recorded as the dependent measures. Laboratory chow biscuits, grapes, apples, and a metal bolt (a tool used to probe for syrup) were used as experimental stimuli. The subjects demonstrated the ability to recognize that exchanges could occur when an experimenter was present with a desirable food. Results indicate that subjects exhibited significant variation in their willingness to barter based upon the types of foods that were both in their possession and presented by the experimenter. Subjects more readily traded chow biscuits for fruit, and more readily traded apples for grapes than grapes for apples. During the exchange of tools and food, the subjects preferred the following in descending order when the probing apparatus was baited with sweet syrup: grapes, metal bolts, and chow biscuits. However when the apparatus was not baited, the values changed to the following in descending order: grapes, chow, and metal bolts. These results indicate that tufted capuchins recognize opportunities to exchange and engage in a simple barter system whereby low-valued foods are readily traded for more highly valued food. Furthermore, these capuchins demonstrate that their value for a tool changes depending upon its utility.     

Sex differences in math performance: The role of children's approach to schoolwork

This research examined whether the tendency for girls to outperform boys in the classroom is due to differences in how girls and boys approach schoolwork. In 5th grade and then again in 7th grade, children (N=518) reported on how they approach schoolwork (i.e., achievement goals and classroom behavior), their learning strategies, and their self-efficacy in math; math grades and achievement test scores were also collected. Girls were more likely than boys to hold mastery over performance goals and to refrain from disruptive classroom behavior, which predicted girls' greater effortful learning over time. The sex difference in learning strategies accounted for girls' edge over boys in terms of grades. Girls did not do better on achievement tests, possibly because self-efficacy, for which there was also no sex difference, was the central predictor of performance on achievement tests.     

Conceptualizing the Influence of Social Agents of Behavior Change: A Meta-Analysis of the Effectiveness of HIV-Prevention Interventionists for Different Groups

A meta-analysis of 166 HIV-prevention interventions tested theoretical predictions about the effects of experts, lay community members, and similar and dissimilar others, as agents of change. In general, expert interventionists produced greater behavior change than lay community members, and the demographic and behavioral similarity between the interventionist and the recipients facilitated behavioral change. Equally importantly, there were differences across groups in the efficacy of various sources, especially among populations of low status and/or power. These findings support the hypothesis that unempowered populations are more sensitive to characteristics of the interventionists who can facilitate access to various resources. In addition, they suggest the need to ensure the availability of health professionals from diverse demographic and behavioral backgrounds.     

Sibling dynamics and group psychotherapy

The role of sibling dynamics in group psychotherapy has received relatively little attention in the literature. Our clinical experience suggests that sibling issues regularly arise in the practice of group psychotherapy. This article provides an integrative view of sibling relationships from a family systems and self psychology orientation to group therapy. Special emphasis is placed on developmental and cultural differences as they affect sibling dynamics and the group leader's role. A number of case examples are offered to illustrate ways to view clinical challenges in a manner consistent with the influence of sibling relationships on group members and group process.
