Predicting psychotherapy benefit: a probabilistic and individualized approach

We describe the development of the probability of treatment benefit (PTB) chart that incorporates, integrates, and extends more recent approaches to describing treatment effects, such as the Reliable Change Index (Jacobson & Truax, 1991) and normative comparisons (Kendall, Marrs-Garcia, Nath, & Sheldrick, 1999), by including parameters that are simultaneously probabilistic and individualized. To illustrate the PTB chart, data are taken from an effectiveness trial (N=139) of a modular treatment for disruptive behavior disorders. The results highlight both individual variability and the probabilistic nature of psychotherapy benefit. Finally, we discuss the utility of the PTB chart in terms of research, policy, and practice implications. Probability tables, such as the PTB chart, have the potential to be used as simple clinical tools to supplement traditional effect sizes and help patients make truly informed decisions about treatment participation.     

Understanding Asian parenting from a Rasch perspective

This study examines the factor structure of Asian child‐reported parenting from a Rasch perspective. Participants comprised 291 sixth graders (11 to 13 years) in Singapore. Six different aspects of parenting were measured, namely warmth, rejection, structure, chaos, autonomy support, and coercion. Rasch Analysis was used to transform ordinal data into linear measures; category functioning was examined; residual‐based principal components were analysed; differential item functioning was assessed; and items and subjects that were misfitting were removed. Results showed that parenting comprised six dimensions, namely warmth, autonomy support, structure‐control, structure‐warmth, chaos, and negative parenting. The findings suggest that it is important for Asian parents to provide guidance to their children (in structure‐control and structure‐warmth) and reaffirms the relevance of warmth in Asian parenting.

Differential hepatic gene expression in the broiler chicken in response to the combined stressors of food withdrawal, catching and transport at the end of production

Broiler (meat) chickens experience the combined acute stressors of food withdrawal, catching and transport (FCT) prior to slaughter as part of normal commercial practice at the end of their lives. This has associated physiological consequences, potentially affecting both welfare and meat quality, some of which are mediated through altered hepatic function. This study compared global hepatic gene expression between control birds and those exposed to commercial FCT using 20K chicken oligonucleotide microarrays. In response to FCT, 733 genes were differentially expressed of which 486 could be mapped onto the genome. The principal molecular and cellular functions thus affected by FCT involved lipid and carbohydrate metabolism with a suppression of mRNA expression for genes involved in lipogenesis, glycolysis and glycogenolysis and an induction of those involved in gluconeogenesis, fatty acid metabolism and ketone synthesis. There was also significant differential expression of genes associated with cellular control and immune function. These stressful events associated with FCT in commercial broiler chickens altered expression of hepatic genes associated with energy metabolism, with exhaustion of stored hepatic and pectoral muscle glycogen. A better understanding of FCT-induced stress through the use of gene expression arrays may in future inform husbandry practices, to improve both welfare and meat quality.     

Risk perception,illusory superiority and personal responsibility during COVID-19: An experimental study of attitudes to staying home

Little is known about how different government communication strategies may systematically affect people’s attitudes to staying home or going out during the COVID-19 pandemic, nor how people perceive and process the risk of viral transmission in different scenarios. In this study, we report results from two experiments that examine the degree to which people’s attitudes regarding the permissibility of leaving one’s home are (1) sensitive to different levels of risk of viral transmission in specific scenarios, (2) sensitive to communication framings that are either imperative or that emphasize personal responsibility, or (3) creating ‘loopholes’ for themselves, enabling a more permissive approach to their own compliance. We find that the level of risk influences attitudes to going out, and that participants report less permissive attitudes to going out when prompted with messages framed in imperative terms, rather than messages emphasizing personal responsibility; for self-loopholes, we find no evidence that participants’ attitudes towards going out in specific scenarios are more permissive for themselves than for others. However, participants report they are more rigorous in staying home than others, which may cause moral licensing. Additionally, we find that age is negatively associated with permissive attitudes, and that male participants are more permissive to going out. Thus, during phases where it is important to promote staying home for all scenarios, including those perceived to be low-risk, imperative communication may be best suited to increase compliance.

Early Positive Information Impacts Final Evaluations: No Deliberation‐Without‐Attention Effect and a Test of a Dynamic Judgment Model

Evaluation judgments were affected by information order and not by subsequent unconscious versus conscious deliberation. In three experiments, we examined the influence of early positive information on final evaluations of four objects. Based on a task analysis, we predicted primacy effects in judgments in a sequential data acquisition task. Thinking periods following presentation were used to manipulate conscious or unconscious processing. In all three studies, we found no effects of thinking manipulations but instead found reliable order effects. We developed and tested an online judgment model on the basis of the belief updating model of Hogarth and Einhorn. The model accounted for large proportion of the individual level variability, and model comparison tests supported the presence of a primacy effect. Copyright © 2013 John Wiley & Sons, Ltd.     

Peak shift in honey bee olfactory learning

If animals are trained with two similar stimuli such that one is rewarding (S+) and one punishing (S?), then following training animals show a greatest preference not for the S+, but for a novel stimulus that is slightly more different from the S? than the S+ is. This peak shift phenomenon has been widely reported for vertebrates and has recently been demonstrated for bumblebees and honey bees. To explore the nature of peak shift in invertebrates further, here we examined the properties of peak shift in honey bees trained in a free-flight olfactory learning assay. Hexanal and heptanol were mixed in different ratios to create a continuum of odour stimuli. Bees were trained to artificial flowers such that one odour mixture was rewarded with 2 molar sucrose (S+), and one punished with distasteful quinine (S?). After training, bees were given a non-rewarded preference test with five different mixtures of hexanal and heptanol. Following training bees’ maximal preference was for an odour mixture slightly more distinct from the S? than the trained S+. This effect was not seen if bees were initially trained with two distinct odours, replicating the classic features of peak shift reported for vertebrates. We propose a conceptual model of how peak shift might occur in honey bees. We argue that peak shift does not require any higher level of processing than the known olfactory learning circuitry of the bee brain and suggest that peak shift is a very general feature of discrimination learning.
