Inferential language processes across adolescence: A test with novel idioms

Idiom comprehension relies on the ability to draw inferences from different cues in a communication situation. Adopting a developmental perspective, we investigated how this ability changes across adolescence. To this end, we designed a computerized system that allowed us to simulate a communication situation through short videos placing participants at the center of the interaction. Four groups of participants (11, 13, 15, and adult students) performed an idiomatic expression comprehension task, in which idiom familiarity was controlled. We manipulated the idioms’ transparency (vs. opacity) and presentation (supportive narrative context inducing an idiomatic interpretation of the expression vs. nonsupportive narrative context). Analyses revealed an improvement in idiom comprehension in terms of contextual inferences but they failed to reveal any significant difference in terms of semantic inferences. This study yields fresh arguments in support of the notion that inferential ability based on context continues to develop beyond childhood.     

The interaction between baseline trait anxiety and trauma exposure as predictor of post-trauma symptoms of anxiety and insomnia

In this study a prospective design was used to investigate the interaction between baseline trait anxiety and exposure to traumatic situations on post-trauma symptoms of anxiety and insomnia in a sample of Swedish peacekeeping soldiers serving in Kosovo. The result showed that pre-trauma trait anxiety interacted with exposure to traumatic situations predicting a higher post-trauma distress. Further, baseline trait anxiety and baseline symptoms of anxiety and insomnia predicted post-trauma symptoms of anxiety and insomnia. The results support a diathesis stress model in which high trait anxiety interacts with trauma exposure in the elicitation of anxiety-related distress but the study needs to be replicated before further conclusions can be drawn.     

Personality traits of the behavioural approach and inhibition systems: associations with processing of emotional stimuli

This study examined the relationships of the traits associated with Gray's behavioural approach system (BAS) and behavioural inhibition system (BIS) with cognitive processing of emotional information. Initially, participants completed questionnaires covering trait impulsivity and anxiety, and BAS and BIS sensitivities. They were then tested individually. After completing a questionnaire of current positive and negative moods, they completed three tasks measuring processing of pleasant, unpleasant and neutral information. Consistent with Gray’s theory, the results showed that impulsivity and BAS sensitivity were associated with the processing of pleasant information, while anxiety and BIS sensitivity were associated with the processing of unpleasant information. These findings imply that Gray’s BAS–BIS theory can be extended to cognitive processing of emotional information.     

Failure to loose fear: The impact of cognitive load and trait anxiety on extinction

Exposure therapy is an effective technique for fear reduction. However, whether effective exposure requires attentional allocation to the feared situation remains a debated clinical issue. In the present study, the impact of attention allocation in extinction was investigated in an experimental conditioning study. Through a between-subjects manipulation of cognitive load, we created a condition in which participants could allocate their attention to the feared stimulus during extinction (low load condition), and a condition in which attentional allocation was impaired (high load condition). The influence of cognitive load on extinction was examined by comparing electrodermal responses and verbal ratings for the conditioned stimuli in the two extinction load conditions. The results show less successful extinction in the high load condition than in the low load condition. However, this effect was found only in low anxious participants, and it was prominent only on the skin conductance responses. The present results suggest that extinction is not automatic but requires cognitive resources.     

Medical diagnostic reasoning: Epistemological modeling as a strategy for design of computer-based consultation programs

The complexity of cognitive emulation of human diagnostic reasoning is the major challenge in the implementation of computer-based programs for diagnostic advice in medicine. We here present an epistemological model of diagnosis with the ultimate goal of defining a high-level language for cognitive and computational primitives. The diagnostic task proceeds through three different phases: hypotheses generation, hypotheses testing and hypotheses closure. Hypotheses generation has the inferential form of abduction (from findings to hypotheses) constrained under the criterion of plausibility. Hypotheses testing is achieved by a deductive inference (from generated hypotheses to expected findings), followed by an eliminative induction, constrained under the criterion of covering, which matches expected findings against patient's findings to select the best explanation. Hypotheses closure is a deductive-inductive type of inference very similar to the inferences operating in hypotheses testing. In this case induction matches the consequences of the generated hypotheses against the patient's characteristics or preferences under the criterion of utility. By using the language exploited in this epistemological model, it is possible to describe the cognitive tasks underlying the most influential knowledge-based diagnostic systems.     

The Comparative Set Fallacy

This paper argues for the validity of inferences that take the form of: A is more X than B; therefore A and B are both X. After considering representative counterexamples, it is claimed that these inferences are valid if and only if the comparative terms in the inference are taken from no more than one comparative set, where a comparative set is understood to be comprised of a positive, comparative, and superlative, represented as {X, more X than, most X}. In all instances where arguments appearing to be of this form are invalid, it is the case that the argument has fallaciously taken terms from more than one comparative set. The fallacy of appealing to more than one comparative set in an inference involving comparative terms is shown to be analogous to the fallacy of equivocation in argumentation. The paper concludes by suggesting a conflation of logical issues with grammatical issues is the core difficulty leading some to consider inferences in the form of A is more X than B; therefore A and B are X to be invalid.     

Exploring the Generalization Process from Past Behavior to Predicting Future Behavior

Substantial evidence in social psychology documents that traits predict behavior. Research in behavioral economics establishes prior behavioral information—the actual behavior of another person in the past—influences future decision making, suggestive of the role of traits in guiding future behavior, but agnostic to the specific psychological mechanism. Yet the entire generalization process from past behavior to predicting future behavior has not been fully explored. Additionally, previous paradigms do not adequately dissociate prediction from explanation, and provide participants with trait information, or rely on participants to generate the appropriate trait. Here, we combine literature and experimental approaches in social psychology and behavioral economics to explore the generalization process from prior behavior that guides future decisions. Across three studies utilizing consequential economic game paradigms and online questionnaires, an initial group of participants (employees) played a time estimation game and a charity donations game before a second group of participants (employers) viewed the behavior of the first group, then decided whether to invest in employees in a trust game and rock guessing game. Although participants infer trait warmth and competence from the behavioral information in the first two games, estimates of normative behavior predicted investment decisions on the warmth‐relevant games better than trait inferences. These results dissociate generalizations guided by warmth and competence behavioral information, and question the extent to which traits always serve as heuristics to predict behavior.

Patterns of language and discourse comprehension skills in school‐aged children with autism spectrum disorders

Åsberg, J. (2010). Patterns of language and discourse comprehension skills in school‐aged children with autism spectrum disorders. Scandinavian Journal of Psychology 51, 534–539. The present study examined patterns of language and discourse comprehension skills in Swedish school‐aged children with autism spectrum disorders (ASD) (n = 16) as compared to a slightly younger group of typically developing children (n = 16) matched for non‐verbal cognitive ability. Results suggested significantly lower abilities in narrative discourse comprehension for the ASD group, but not in oral receptive vocabulary or reception of grammar. This difficulty with discourse‐level comprehension appeared to be of a general nature, as no evidence was found for the hypothesis that participants with ASD would find comprehension of inferential discourse information disproportionally more difficult than stated information, or for the hypothesis that discourse processing in ASD would be characterized by an elevated processing of explicitly stated narrative details. The study has clinical and educational implications, as the findings suggest that children with ASD would benefit from being offered specific support for discourse‐level comprehension.     

ANXIETY SENSITIVITY AND TRAIT-SYMPTOM MEASURES OF ANXIETY AND DEPRESSION

The Icelandic version of the Anxiety Sensitivity Index was investigated in two studies of college students. A principal components analysis of ASI scores from both studies (N=718) yielded three components similar to what has been found previously: Psychological Concerns, Physical Concerns and Social Concerns. In the first study the relationship between the ASI and trait anxiety was investigated. It was analysed at the level of the total scales but also at the level of subscales of both instruments. Two subscales of the STAI, measuring respectively Anxiety-trait and Depression-trait, were used as well as the Psychological Concerns and Physical Concerns subscales of the ASI. In a second study the relationships between ASI and its subscales and two symptom measures of anxiety and depression were addressed. ASI was in both studies more strongly related to the anxiety than the depression scales. Also, in both studies the Physical Concerns subscale of the ASI was more strongly related to anxiety than to depression, whereas the Psychological Concerns subscale was equally related to anxiety and depression. Taken together the studies support the notion of different relationships between different aspects of anxiety sensitivity, and anxiety and depression as traits, cognitive symptoms and mood related symptoms.
