Concept of uprightness in baboons: assessment with pictures of realistic scenes

How nonhuman primates process pictures of natural scenes or objects remains a matter of debates. This issue was addressed in the current research by questioning the processing of the canonical orientation of pictures in baboons. Two adult guinea baboons were trained to use an interactive key (IK) on a touch-screen to change the orientation of target pictures showing humans or quadruped mammals until upright. In experiment 1, both baboons successfully learned to use the IK when that key induced a 90 degrees rightward rotation of the picture, but post-training transfer of performance did not occur to novel pictures of natural scenes due to potential motor biases. In Experiment 2, a touch on IK randomly displayed the pictures in any of the four cardinal orientations. Baboons successfully learned the task, but transfer to novel pictures could only be demonstrated after they had been exposed to 360-480 pictures in that condition. Experiment 3 confirmed positive transfers to novel pictures, and showed that both the figure and background information controlled the behavior. Our research on baboons therefore demonstrates the development and use of an "upright" concept, and indicates that picture processing modes strongly depend on the subject's past experience with naturalistic pictorial stimuli.     

Spousal similarity in coping and depressive symptoms over 10 years.

Following a baseline sample of 184 married couples over 10 years, the present study develops a broadened conceptualization of linkages in spouses' functioning by examining similarity in coping as well as in depressive symptoms. Consistent with hypotheses, results demonstrated (a) similarity in depressive symptoms within couples across 10 years, (b) similarity in coping within couples over 10 years, and (c) the role of coping similarity in strengthening depressive similarity between spouses. Spousal similarity in coping was evident for a composite measure of percent approach coping as well as for component measures of approach and avoidance coping. The role of coping similarity in strengthening depressive symptom similarity was observed for percent approach coping and for avoidance coping. These findings support social contextual models of psychological adjustment that emphasize the importance of dynamic interdependencies between individuals in close relationships.     

Using Selective Redundancy to Eliminate the Seductive Details Effect

The seductive details effect occurs when adding interesting, but extraneous, details to a lesson impairs learning of the lesson's key information. Although instructors could simply remove such interesting details, prior research suggests that interest can be a powerful motivating factor for learning. In the present research, we attempted to recruit the motivational benefits of seductive details without eliciting their detrimental effects by manipulating the redundancy between narrated and on‐screen verbal information within a multimedia lesson. We presented 69 college students with different instructional videos, one in which key facts were presented with on‐screen text slightly different from the narration, while seductive details were presented with on‐screen text that was identical to the narration. We eliminated the seductive details effect for these participants, indicating that partial redundancy can be used as a means by which interesting details can be included in a lesson without detracting from the learning of key facts.Copyright © 2017 John Wiley & Sons, Ltd.     

Metacognition and proofreading: the roles of aging,motivation, and interest

The current study examined younger and older adults’ error detection accuracy, prediction calibration, and postdiction calibration on a proofreading task, to determine if age-related differences would be present in this type of common error detection task. Participants were given text passages, and were first asked to predict the percentage of errors they would detect in the passage. They then read the passage and circled errors (which varied in complexity and locality), and made postdictions regarding their performance, before repeating this with another passage and answering a comprehension test of both passages. There were no age-related differences in error detection accuracy, text comprehension, or metacognitive calibration, though participants in both age groups were overconfident overall in their metacognitive judgments. Both groups gave similar ratings of motivation to complete the task. The older adults rated the passages as more interesting than younger adults did, although this level of interest did not appear to influence error-detection performance. The age equivalence in both proofreading ability and calibration suggests that the ability to proofread text passages and the associated metacognitive monitoring used in judging one’s own performance are maintained in aging. These age-related similarities persisted when younger adults completed the proofreading tasks on a computer screen, rather than with paper and pencil. The findings provide novel insights regarding the influence that cognitive aging may have on metacognitive accuracy and text processing in an everyday task.     

Baseline measurement of running away among youth in foster care

The current study evaluated the use of various behavioral measures of running away with regard to (a) the differential utility of interval- versus event-based measures, (b) the differential utility of rate versus duration measures, (c) the utility of correcting for occurrence opportunity, and (d) the influence of unit of analysis (i.e., single-subject vs. grouped data). Seven different baseline measures were calculated for 84 runaways, and a unit-size analysis was conducted by constructing groups of various sizes from the original sample. An expert panel evaluated the suitability of the baseline measures for treatment evaluation. Results demonstrate the utility of evaluating duration-based measures and correcting for occurrence opportunity. Results also indicate that single-subject baselines may often be unacceptable for treatment evaluations, regardless of the type of measure selected for use.     

Youth-Adult Partnerships in Decision Making: Disseminating and Implementing an Innovative Idea into Established Organizations and Communities

The principles and processes for engaging youth-adult partnerships (Y-AP) in organizational and community decision making have often been articulated from developmental and social justice perspectives. A broad empirical foundation for Y-AP has been established. Y-AP remains an innovative idea in the United States, however. The belief that youth and adults can, and should, collaborate on issues of importance runs counter to prevailing policies, institutional structures, and community norms. 4-H Youth Development is one public system that is actively seeking to disseminate and implement Y-AP. 4-H Youth Development seeks to integrate Y-AP into its own governance structures as well as those of local government and community coalitions. Through qualitative analysis of the efforts in one Midwestern state, this study examines the contextual challenges faced by county staff-the providers of program support within 4-H Youth Development-and the ways in which county staff respond to these obstacles. This project identifies the goals, leverage points, and strategies through which county staff seek to integrate Y-AP into established forums of decision making. Implications for the dissemination and implementation of principle and process-based innovation are offered, with special attention to the role of the program support system.
