Infelicitous Cancellation: The Explicit Cancellability Test for Conversational Implicature Revisited

This paper questions the adequacy of the explicit cancellability test for conversational implicature as it is commonly understood. The standard way of understanding this test relies on two assumptions: first, that that one can test whether a certain content is (merely) conversationally implicated, by checking whether that content is cancellable, and second, that a cancellation is successful only if it results in a felicitous utterance. While I accept the first of these assumptions, I reject the second one. I argue that a cancellation can succeed even if it results in an infelicitous utterance, and that unless we take this possibility into account we run the risk of misdiagnosing philosophically significant cases.     

The combined influence of hardiness and cohesion on mental health in a military peacekeeping mission: A prospective study

A large number of studies have shown that hardiness and cohesion are associated with mental health in a military context. However, most of them are presented without controlling for baseline mental health symptoms, which is their most significant source of error. The present study investigates the combined effect of hardiness and cohesion in a prospective design, controlling for baseline levels of symptoms among Norwegian personnel serving in a peacekeeping operation in Kosovo. Multivariate regression analyses were performed in which self‐reported mental health complaints were regressed on our explanatory variables. Our findings suggest that both cohesion and hardiness contributed to increased stress resiliency, as measured by a lower level of reported mental health complaints. Our baseline measure of mental health accounted for a larger proportion of the variance than our other predictors. A significant interaction between cohesion and hardiness suggested a combined effect, over and above the individual contributions of the predictors. For individuals who scored high on hardiness, cohesion levels did not influence levels of mental health complaints. Individuals who scored low on hardiness, on the other hand, reported lower levels of mental health complaints when cohesion levels were high.     

Do we look happy? Perceptions of romantic relationship quality on Facebook

Does the information that people share about their romantic relationships on Facebook influence how other people perceive their relationship quality? Across 2 studies, people's accuracy at inferring others' relationship quality based on their Facebook profiles and how Facebook profiles influenced others' judgments of people's relationship quality and likability were investigated. Perceived relationship quality corresponded to self‐reported relationship quality (Study 1), and people with more visible relationships were perceived as having greater relationship satisfaction and commitment (Studies 1 and 2) and being more likable (Study 2). High disclosure about the relationship predicted greater perceived relationship quality but lower likability (Study 2). These findings illuminate how sharing information about one's relationship influences other people's impressions of the individual and the relationship.     

The effect of hardiness on PTSD symptoms: A prospective mediational approach

Psychological hardiness has been associated with lower PTSD in military personnel, but the processes of action remain unclear. This study uses a prospective design to examine whether hardiness has an indirect effect on PTSD symptoms through avoidance coping. Our sample included 163 Norwegian military personnel who served in international operations between 2009 and 2010. Regression analyses were performed to estimate the coefficients in a simple mediation model, with baseline PTSD symptoms, combat exposure, and deprivation of basic needs entered as control variables. The results showed that the effect of hardiness on PTSD symptoms worked through reducing the use of avoidance coping. It was concluded that an avoidant-focused coping style acts as a vulnerability factor for PTSD symptoms, whereas hardiness acts as a resilience factor against symptoms development.     

Reliability and validity of the Norwegian translation of the Child Eating Disorder Examination (ChEDE)

Frampton, I., Wisting, L., Øverås, M., Midtsund, M. & Lask, B. (2011). Reliability and validity of the Norwegian translation of the Child Eating Disorder Examination (ChEDE). Scandinavian Journal of Psychology 52, 196–199. The Child Eating Disorder Examination (ChEDE) is a valid and reliable semi‐structured interview, which measures eating‐disorder specific psychopathology in children and young adolescents. The instrument is an adaptation of version 12.0D of the original Eating Disorder Examination (EDE 12.0) for adults. The Norwegian translation of the ChEDE is currently the only instrument for assessing eating disorder psychopathology in Norwegian children and adolescents. This study aimed to investigate the psychometric properties of the Norwegian translation of the ChEDE 12.0. The Norwegian version of ChEDE 12.0 was administered to 15 Norwegian children with anorexia nervosa (AN), 15 children with diabetes mellitus type 1 (DM) and two groups of 15 age‐matched controls. The groups were compared using a matched pairs design. The results showed that the subscale scores of the AN group were significantly higher than those of the other groups, and the DM comparison group did not differ from its control group. The current AN group scored significantly higher on the Shape Concern subscale than the previous UK sample, with implications for construct validity or cross‐cultural effects worthy of further study. Inter‐rater reliability was generally high (r = 0.91 to 1.00), although there were significant differences between raters on specific items for individual participants. Alpha coefficients for each of the ChEDE subscales indicated a high degree of internal consistency. It was concluded that the Norwegian version of the ChEDE 12 has adequate psychometric properties and can be recommended for clinical and research use with young people with eating disorders in Norway.     

Women Assimilate Across Gender,Men Don't: The Role of Gender to the Own‐Anchor Effect in Age,Height, and Weight Estimates1

This paper reports 2 studies of the own‐anchor effect (i.e., assimilation in age, height, and weight estimates) in same‐ and cross‐gender age, height, and weight estimates. The own‐anchor effect is believed to be stronger for same‐gender estimates, but the investigation reported here is the first to test this hypothesis with participants and target persons of both genders. Several own‐anchor effects were found in females' same‐ and cross‐gender estimates, whereas males only showed own‐anchor effects in same‐gender estimates. These results lean toward the possibility that women assimilate across gender, whereas men do not. Explanations of these results with reference to Krueger's ( Krueger & Zeiger, 1993 ; Robbins & Krueger, 2005 ) theory of social projection and the consequences for witness reliability are discussed.     

A mediation analysis of achievement motives,goals, learning strategies,and academic achievement

Background. Previous research is inconclusive regarding antecedents and consequences of achievement goals, and there is a need for more research in order to examine the joint effects of different types of motives and learning strategies as predictors of academic achievement. Aims. To investigate the relationship between achievement motives, achievement goals, learning strategies (deep, surface, and strategic), and academic achievement in a hierarchical model. Sample. Participants were 229 undergraduate students (mean age: 21.2 years) of psychology and economics at the University of Bergen, Norway. Methods. Variables were measured by means of items from the Achievement Motives Scale (AMS), the Approaches and Study Skills Inventory for Students, and an achievement goal scale. Results. Correlation analysis showed that academic achievement (examination grade) was positively correlated with performance‐approach goal, mastery goal, and strategic learning strategies, and negatively correlated with performance‐avoidance goal and surface learning strategy. A path analysis (structural equation model) showed that achievement goals were mediators between achievement motives and learning strategies, and that strategic learning strategies mediated the relationship between achievement goals and academic achievement. Conclusions. This study integrated previous findings from several studies and provided new evidence on the direct and indirect effects of different types of motives and learning strategies as predictors of academic achievement.

INCREASING THE ACCURACY OF CORRECTIONS FOR RANGE RESTRICTION: IMPLICATIONS FOR SELECTION PROCEDURE VALIDITIES AND OTHER RESEARCH RESULTS

The common practice in meta-analyses and in individual studies of correcting for direct range restriction even though range restriction is actually indirect has long been known to lead to undercorrection, but this error has been assumed to be small. Using validity generalization data sets for 4 jobs, this study calibrated this error by comparing meta-analysis results based on corrections for direct range restriction with the more accurate results from a recently developed method of correcting for indirect range restriction. It was found that, on average, correction for direct range restriction resulted in substantial underestimation of operational validities for both job performance measures (21%) and training performance measures (28%). In addition, 90% credibility values were on average underestimated by 38%–40%. In addition to the implications for personnel selection, these findings suggest that similar underestimation of important relationships has occurred in other areas of research, with potential implications for theory development.     

Episodic memory change in late adulthood: Generalizability across samples and performance indices

Younger adults recall more information from episodic memory tasks than do older adults. Because longitudinal studies are rare and often incompatible, the extent of actual late-life memory change is not well established. We assemble two different longitudinal samples of normal older adults, each of which is tested twice at a 3-year interval, using a large battery of episodic memory indicators. Together, two-wave data from both the Victoria Longitudinal Study in Canada (n = 400) and the Kungsholmen Project in Sweden (n = 168) cover a 40-year span of adulthood, ranging from 54 to 94 years of age. Principal memory tasks include categorizable word lists, story recall, and random word lists, as well as indicators of cognitive support. Overall, an examination of performance on sets of common and complementary episodic tasks reveals that, for both samples, actual 3-year changes are modest and that, when decline occurs, it is gradual. The exception-greater decline for more supported tasks-suggests that these may be especially sensitive to late-life changes.
