The Relative Effects of Abstract Versus Concrete Processing on Proactivity in Depression

Low levels of proactivity are characteristic of individuals with depression. Two studies were conducted to compare the relative effects of abstract versus concrete processing on proactivity in high dysphoric individuals. In Study 1, participants read information about an upcoming research study and were then randomly allocated to a writing task that induced them to think about participating in that study in either an abstract (e.g., Why you would participate in the study?; n = 25) or concrete (e.g., How you will participate in the study?; n = 25) way. Participants were then asked to indicate whether they would sign up to the study. As expected, more participants indicated that they would take part in the study in the concrete condition (76%) than in the abstract condition (36%). In Study 2, high dysphoric participants were asked to identify their ideal part-time job and were then randomly allocated to a writing task that induced them to think about applying for the job in an abstract (n = 26) or concrete (n = 25) way. There was no difference between conditions in self-reported intentions of proactivity. However, significantly more participants in the concrete condition opted to look at an employment assistance website and returned to the lab to collect a job application package. Overall, these findings suggest that abstract processing could contribute to low levels of proactivity in depression, and that facilitating the use of concrete processing could help to alleviate this problem. Our results also point to the need for greater conceptual clarification of the distinction between concrete processing about proactive behavior and implementation intentions (identifying specific steps for completing an action/goal).     

Temperament as Risk and Protective Factors in Obesogenic Eating: Relations Among Parent Temperament,Child Temperament,and Child Food Preference and Eating

Children’s food preferences and eating behaviors have implications for their health and weight status, serving as risk or protective factors for obesity. Although parent and child factors influence children’s eating, few studies have examined parent and child temperament simultaneously in relation to child food preference and eating behaviors. The authors addressed this research gap. Participants were 115 ethnically diverse children between 4 and 6?years old and their parents. Measures included parental temperament traits, parental anxiety, child temperament traits, and child food preference and eating behaviors observed using a laboratory procedure. Results show that children preferred candies over grapes, and that aspects of both child and adult temperament were related to child eating behaviors. Child surgency was linked to eating more candies, while child effortful control was linked to eating more grapes. Parent effortful control was related to children’s preference toward grapes. No relations were found between child eating behaviors and child or parent negative affectivity and parental anxiety. Overall, findings suggest that highly impulsive and poorly self-regulated children may be at risk for obesogenic eating habits.     

Gleaning Information for Cognitive Operations from Don’t Know Responses in Cognitive and Noncognitive Assessments

The Don’t Know (DK) response – taking the form of an omitted response or not-reached at the end of a cognitive test, or explicitly presented as a response option in a social survey – contains important information that is often overlooked. Direct psychometric modeling efforts for DK responses are few and far between. In this article, the linear logistic test model (LLTM) is proposed for delineating the impacts of cognitive operations for a test that contains DK responses. We assume that the DK response is a valid response. The assumption is reasonable for many situations, including low-stakes cognitive tests and attitudinal assessments. By extracting information embedded in the DK response, the method shows how DK can inform the latent construct of interest and the cognitive operations underlying the response to stimuli. Using a proven recoding scheme, the LLTM could be implemented through commonly used programs such as PROC GLIMMIX. Two simulation experiments to evaluate how well the parameters can be recovered were conducted. In addition, two real data examples, from a noncognitive test of health belief assessment and a cognitive test of knowledge in diabetes, are also presented as case studies to illustrate the LLTM for DK response.     

Attaining landmark status: Rumelhart and McClelland's PDP Volumes and the Connectionist Paradigm

In 1986, David Rumelhart and James McClelland published their two‐volume work, Parallel distributed processing: Explorations in microcognition, Volume 1: Foundations and Volume 2: Psychological and biological models. These volumes soon become classic texts in both connectionism, specifically, and in the cognitive science field more generally. Drawing on oral histories, book reviews, translations, citation records, and close textual analysis, this paper analyzes how and why they attained landmark status. It argues that McClelland and Rumelhart's volumes became classics largely as a result of a confluence of rhetorical factors. Specifically, the PDP Volumes appeared at a kairotic moment in the history of connectionism, publishing dynamics that facilitated their circulation played an important role, and the volumes were ambiguous about the relationship between model and brain in a manner that enabled them to address an expansive audience. In so doing, this paper offers insight into both the history of cognitive science and rhetoric's role in establishing classic texts.     

Social and Temporal Comparisons Made by Individuals Living With HIV Disease: Relationships to Adherence Behavior1

When faced with the uncertainty of serious illness, individuals cope by comparing themselves to other people (social comparisons) and to other times in their lives (temporal comparisons). Participants were 44 individuals being treated for HIV who completed questionnaires measuring comparisons, adherence, and self‐efficacy; 34 also completed qualitative interviews that were coded for comparisons. High levels of comparison to worse‐off others, worse‐off past selves, and better‐off future selves were prevalent. Comparisons to worse‐off others resulting in positive affect were associated with greater medication adherence; comparisons to better‐off others resulting in negative affect were related to worse adherence. Self‐efficacy to adhere mediated the relationship between comparison and adherence. Individuals who are uncertain about treatment outcomes may engage in social comparison to gain specific knowledge about adherence.     

Latino/a Theology: Doing Theology Latinamente

Latino/a Theology is rising among theologians of Latin American descent in the United States. This article describes five characteristics: 1) it is specific to the cultural context of marginalized Hispanic history; 2) it focuses on the theme of mestizaje/mulatez, the biological and cultural mixing of European Spanish with Africans and indigenous Americans; 3) it derives from popular religion; 4) it deals with everyday life, lo cotidiano; 5) like liberation theology, it emphasizes praxis.     

The Effect of Scopolamine in Older Rabbits Tested in the 750 ms Delay Eyeblink Classical Conditioning Procedure

We investigated the effect of several doses of scopolamine in older rabbits that were trained for 20 days in the 750 ms delay eyeblink classical conditioning procedure. Our aim was to determine if the scopolamine-injected older rabbit would be a useful model for testing drugs for cognition enhancement in Alzheimer's disease (AD). A total of 39 rabbits with a mean age of 31 months received classical eyeblink conditioning with daily injections of 0.25, 0.75, or 1.5 mg/kg scopolamine hydrobromide or sterile saline vehicle. Doses of 0.75 and 1.5 mg/kg scopolamine significantly impaired acquisition, whereas acquisition was not significantly impaired with 0.25 mg/kg scopolamine. Results exhibit parallels in performance on delay eyeblink classical conditioning between scopolamine-treated older rabbits and human patients diagnosed with AD.
