An experimental evaluation of a prototype public access nutrition information system for supermarkets

Located the Nutrition for a Lifetime System (NLS-1), a prototype interactive information system, in a large supermarket to help users decrease high-fat food purchases and increase high-fiber food purchases. Study participants were randomly assigned to control (n = 23; used the NLS-1 to enter food purchases only) or experimental (n = 26; viewed videodisc instructional programs, received prompts, made commitments, received feedback from the NLS-1) conditions. According to data entered in the NLS-1 and actual food shopping receipts, experimental participants significantly reduced higher fat purchases. Increases in higher fiber purchases favored the experimental group but were not significant.     

Further investigation of increasing vocalizations of children with autism with a speech-generating device

We replicated and extended the findings of Gervarter et al. (2016) by using prompting and reinforcement to produce increased vocal speech with 3 young children diagnosed with autism spectrum disorder (ASD) who used a speech generating device (SGD). We extended Gervarter et al. by adopting a more robust experimental design, conducting session-by-session preference assessments, and measuring the emergence of novel vocalizations. The frequency of vocalizations increased for all 3 participants after the introduction of an echoic prompt. These results suggest that SGD-based interventions may lead to increased vocal output for children with ASD.     

Reducing risk of head injury in youth soccer: An extension of behavioral skills training for heading

Recently, concerns regarding sport-related concussions have increased within the research literature, the media, and popular culture. One potential source of soccer-related concussions involves the purposeful striking of the ball with one's head (i.e., heading). There is currently limited research on an effective teaching method to improve safe heading technique. In the current study, Behavior Skills Training (BST) was evaluated as a method to teach correct heading techniques to youth soccer players. BST increased the percentage of correct steps for each player based on a task analysis of heading. Based on social validity questionnaires administered to players and the coach, BST was rated as an acceptable form of training. After the final training session, experienced coaches rated each player as having improved from baseline to training.     

Effects of text difficulty and adults' age on relative calibration of comprehension

Weaver and Bryant (1995) proposed the optimum effort hypothesis, suggesting that undergraduate students were better able to predict comprehension when text materials matched their reading level (grade 12) as opposed to being too easy or too difficult (Weaver and Bryant did not assess the actual reading level of their participants). In the study, we examined the reading level and accuracy of performance prediction of both younger and older adults using Weaver and Bryant's materials. Regardless of our participants' high reading levels (grade 14 and above), they still predicted performance best when texts were written at around the grade 12 level, failing to support the optimum effort hypothesis.     

Intrahippocampal wortmannin infusion enhances long-term spatial and contextual memories

The transition from short- to long-term memory involves several biochemical cascades, some of which act in an antagonistic manner. Post-training intrahippocampal administration of wortmannin, a pharmacological inhibitor of phosphatidylinositol 3-kinase, had no effect on memory tested 3 h later, but improved long-term memory tested 48 h following the completion of training. This effect was seen in two hippocampus-dependent tasks: the Morris water maze, using both massed and distributed training paradigms, and contextual fear conditioning. The improvement of long-term memory appears to be the result of enhanced consolidation, as wortmannin had no effect on memory recall. These results are consistent with the hypothesis that memory consolidation involves competing processes, and that blockade of an inhibitory constraint facilitates the consolidation process.     

Prenatal stress alters early neurobehavior, stress reactivity and learning in non-human primates: a brief review

In this paper we review three prospective longitudinal studies from our laboratory examining the effects of prenatal stress on early neuro behavior, stress reactivity and learning performance in rhesus monkeys. Either a noise stressor or ACTH treatment was administered to pregnant monkeys during specific periods of pregnancy and offspring were examined repeatedly across development. In all three studies, the prenatally stressed monkeys showed reduced attention and impaired neuromotor functioning during the first month of life compared to controls from undisturbed pregnancies. When the monkeys were separated from their mothers or peers at 6-8 months of age, prenatally stressed monkeys exhibited more disturbance behavior and showed hypothalamic-pituitary-adrenal axis dysregulation. During adolescence, they exhibited impairments in learning, compared to controls.     

An Evaluation of a Holistic Program for at-Risk Teens and Their Parents

Increasing evidence indicates that adolescent behavior problems are related to family functioning. In general, findings have demonstrated the family’s critical role in facilitating developmental outcomes. This study evaluated a 6-week holistic program for at-risk teens and their parents entitled Creating a Responsible Thinker at baseline, post-test, and 3-month follow-up. Results demonstrated gender differences in the program’s effects on self-efficacy, specifically increased self-efficacy for females and reduced self-efficacy among males. Follow-up results suggested that teens reported better communication with their parents. These results underscore the appropriateness of a family-based approach to treatment for at-risk teens and their parents.     

Depression, constructive thinking and patient satisfaction in cardiac treatment adherence

Many patients fail to adhere to prescribed treatment regimens, particularly patients who are depressed. This study examined the link between depression and adherence among 92 patients undergoing post-operative cardiac rehabilitation. Self-reported adherence was measured in terms of both general recommendations and specific health behaviours. Greater depression was associated with general - but not specific - adherence, and this relationship was mediated by lower satisfaction with their doctor - patient interactions. The link between depression and patient satisfaction was itself mediated by less constructive thinking among patients. These results suggest that adherence among cardiac rehabilitation patients may be enhanced by addressing patients' cognitive coping, and by improving the quality of their doctor - patient interactions.     

The Varieties of Forgiveness Experience: Working toward a Comprehensive Definition of Forgiveness

The definition of forgiveness was explored in a group of 270 young adults, and the underlying dimensions of their definitions compared with those of philosophers, theologians and psychological researchers. Three dimensions were identified: orientation (self, other), direction (passive letting go of negative experiences, active enhancement of positive experiences) and form (emotion, cognition and behavior). Definitions employing a passive letting go of negative experiences were associated with more state forgiveness. Gender differences were found in state forgiveness and in the employment of passive vs. active dimensions of forgiveness. Dr. Kathleen A. Lawler-Row is Professor of Psychology at East Carolina University. Her work focuses on the physiological and health correlates of forgiveness. Correspondence to Dr. K. A.
