Examining the cross‐cultural validity of the positive affect and negative affect schedule between an Asian (Singaporean) sample and a Western (American) sample

The positive affect and negative affect schedule (PANAS) is a popular measure of positive (PA) and negative affectivity (NA). Developed and validated in Western contexts, the 20‐item scale has been frequently administered on respondents from Asian countries with the assumption of cross‐cultural measurement invariance. We examine this assumption via a rigorous multigroup confirmatory factor analysis, which allows us to assess between‐group differences in both strength of scale item‐to‐latent factor relationship (metric invariance test) and mean of each scale item (scalar invariance test), on a large sample of 1,065 respondents recruited from Singapore (Asian sample) and the United States (Western sample). We found that two items assessing PA (“excited” and “proud”) and three items assessing NA (“guilty,” “hostile,” and “ashamed”) exhibited metric noninvariance whereas 11 of the remaining metric invariant items exhibited scalar noninvariance, suggesting that the PA and NA constructs differ from what the PANAS is expected to measure for Asian respondents. Our findings serve as a cautionary note to researchers who intend to administer the PANAS in future studies as well as to researchers interpreting the results of past studies involving respondents from Asian countries.     

Word‐of‐mouth information processing routes: The mediating role of message and source characteristics

This study investigates word‐of‐mouth (WOM) information processing routes from active WOM seeking behaviour. Employing the elaboration likelihood model (ELM), the direct and indirect effects of factors within information processing routes are examined in a credence service context. A deeper exploration of the causal chains of each route was conducted using serial mediation models of message quality and source characteristics. Data were collected in the higher education context from a survey of 509 high school students applying for tertiary study. Findings indicate that active WOM seeking and the serial mediation effects elicit two routes of information processing: central and peripheral. This study is amongst the first to intensively reveal the underlying causal chains of WOM processing and supports the application of ELM theory in WOM research.     

When the bullied peer is native-born vs. immigrant: A mixed-method study with a sample of native-born and immigrant adolescents

An increasing number of immigrant students attend Italian schools, with the possibility of being involved in bullying episodes. A few studies have investigated this phenomenon, providing some evidence that immigrant students may face an increased risk of being bullied compared to native-born students. The present study adopted a mixed-method design, which may better detect the dynamics of bullying towards immigrant peers. Participants were 692 native-born and immigrant students (20.5% with immigrant background; 54.8% females) who filled in self-report measures about their bullying experiences, popularity, acceptance of diversity at school, and prejudice. Thirty-five pupils (54% with immigrant background) were also interviewed. Two hypothetical bullying scenarios were presented: one depicting a native-born victim and one depicting an immigrant victim. After each scenario, adolescents were encouraged to reason about the motives for bullying. Quantitative data showed that general bullying was associated with perceived popularity status among peers, while racial bullying was associated with prejudice but not peer status. The relevance of anti-immigrant prejudices in driving racial bullying emerged also from adolescents’ interviews. The qualitative data indicated that among the reasons for bullying, adolescents mentioned a desire for dominance and popularity, in particular when the victim was non-immigrant. Findings suggest that, in addition to individual and peer group-related risk factors, prejudice also needs to be addressed in anti-bullying interventions aimed to counteract racial bullying.     

Roles of Boredom and Life Goals in Juvenile Delinquency1

The relationship between possible selves and boredom in juvenile delinquency was examined in 418 high school students. The construct Possible Selves refers to the representation of the self that each person would like to become, could become, and is afraid of becoming. Participants who acknowledged high levels of delinquent behaviors reported more negative possible selves, a higher tendency to experience boredom, and fewer positive possible selves than did adolescents who engaged in lower levels of delinquent behaviors. Also, the number of negative possible selves, the number of positive possible selves, boredom proneness, and gender accounted for 32% of the variance in juvenile delinquency. Overall, the results provide evidence that boredom and a negative view of one's future play a significant role in adolescent delinquent behavior.     

Meal patterns following changes in procurement cost for rats with fornix transection

The purpose of the present study was to explore the effects of a varied procurement cost on the foraging behavior of rats with fornix transection. An operant analog of foraging requirements was used to examine the feeding patterns of the animals under free feeding, low procurement cost (FR5), and high procurement cost (FR80) situations, in an environment with minimal sensory distraction. It was found that animals with fornix transection did not differ from control rats in general consumption. Both groups were also able to adapt their feeding behavior to the varied procurement cost. As the procurement cost increased, the number of meals consumed decreased while the meal duration increased. The meal patterns themselves were different for the fornix transected animals and the control group. Animals with fornix transections ate more meals over the course of a day than did control animals; their meals were of a longer duration, and their intermeal intervals were shorter than those of control animals. During the course of a meal, the rats with fornix transections took a larger number of breaks, during which they drank, explored, or engaged in activities other than eating. These differences in the feeding patterns were seen across all procurement cost levels. The data support the possibility of hippocampal involvement in behavioral organization or sequencing.     

Response variation in instrumental extinction in rats with fornix transections

The present experiment examined spatial and response variation interpretations of the large difference in magnitude between operant and instrumental extinction deficits seen in hipocampally damaged animals. Latency measures and detailed behaviors of rats with fornix transections were compared to those of control rats during acquisition and extinction in an enriched spatial runway. Control rats, in comparison to rats with fornix transections, exhibited larger increases in start box, runway, and goal box latencies, but no spatial gradients were found. Control rats also exhibited less goal persistence and more response variation following the transition to extinction. The results suggest no fundamental difference between operant and instrumental deficits following hippocampal damage, but an interaction between strategies employed and traditional response measures.     

Transfer of contextual stimulus function via equivalence class development

In a conditional discrimination, 6 college students arranged six Cyrillic letters into groups of three based upon which of two additional Cyrillic letters (contextual stimuli) was present. All subjects demonstrated symmetry and transitivity within each class of equivalent stimuli. In a second conditional discrimination, two more Cyrillic letters were related to each contextual stimulus. Testing of symmetrical and transitive relations between the original contextual stimulus and the two new ones confirmed the development of two three-member classes of contextual stimuli. Subsequent tests demonstrated that the new contextual stimuli controlled the previously trained sample-comparison relations for all subjects.
