Bidimensional Emotional Health in College Students: a Comparison of Categorical and Continuous Analytic Approaches

This study reports on an investigation of the concurrent validity of the bidimensional model of emotional health, using two analytic approaches—one categorical and the other continuous—with two subsamples of college students. Results from the categorical approach, using analyses of variance with the first subsample (n = 461), indicated that, compared to isolated emotional wellbeing and distress models, the bidimensional model of emotional health had incremental validity in relation to social connectedness, life satisfaction, physical health, and academic achievement outcomes. Findings from the continuous approach, using latent-variables path analyses with the second subsample (n = 490), indicated that the isolated emotional wellbeing model was a better predictor of the aforementioned quality-of-life outcomes than were the bidimensional and isolated distress models. Taken together, findings from both sets of analyses suggest that emotional wellbeing is a distinguishing predictor of college student outcomes. Implications for the theory and practice of mental health work at the college level are discussed.     

The Word Superiority Effect in central and peripheral vision

The Word Superiority Effect (WSE) is a well-known phenomenon in reading research, where words are reported more accurately than single letters or non-words. We report two experiments that investigate the WSE in the central and peripheral visual field, as well as laterality differences in the perception of words and letters, using methods based on the Theory of Visual Attention. The results show a WSE in the central visual field, reflected in mean scores, perception thresholds, and processing speed, whereas the effect is eliminated or reversed in the periphery. This may be caused by crowding, which prevents lexical analysis of a word in the periphery. We conclude that perception of words and letters differs according to location in the visual field. Linking our results to previous studies of crowding effects in patients with reading impairments, we hypothesize that similar mechanisms may limit normal word peripheral processing.     

Countermeasures Against the Strategic Use of Evidence Technique: Effects on Suspects' Strategies

As the Strategic Use of Evidence (SUE) technique becomes more widely taught to practitioners, it is important to investigate possible countermeasures to the technique. It is possible that guilty suspects who are aware of the SUE technique will employ forthcoming verbal strategies to make themselves appear innocent. Mock suspects committed a richly detailed simulated transgression (or a benign analogue) and were interviewed about their activities. Prior to questioning, some suspects received information about SUE tactics the interviewer was likely to use. Guilty suspects who were informed about the SUE technique employed more verbally forthcoming strategies than their uninformed counterparts. Guilty suspects who were given SUE information also reported planning for the interview in different ways. However, guilty‐informed suspects did not become as forthcoming as innocent suspects overall. In sum, it appears that information about the SUE technique induces guilty suspects to alter their strategies, but only to a relatively small degree.Copyright © 2015 John Wiley & Sons, Ltd.     

Preference or ability: Exploring the relations between risk preference,personality, and cognitive abilities

Key issues in the behavioral sciences are if there exist stable risk preferences that generalize across domains and if these are best measured by revealed risk preference (RRP) in behavioral decision tasks or by surveys eliciting stated risk preference (SRP). We applied network analysis to data from a representative Swedish sample to investigate the relations between RRP, SRP, personality characteristics, and cognitive abilities, using in total over 70 measurements. The results showed that different measures of RRP were poorly intercorrelated and formed a community together with measures of numerical and cognitive abilities. Measures of SRP were weakly correlated with measures of RRP and identified in a distinctly separate community, along with personality characteristics and gender. The ensuing analyses provided support for a model suggesting that RRPs are contaminated by demands on numerical and cognitive abilities. RRPs may thus suffer from poor construct validity, whereas SRPs may better capture people's everyday risk preferences because they are related to more stable traits.

Maternal well-being and sleep–wake behaviors in infants: An intervention using maternal odor

The development of an organized sleep–wake cycle in young infants is influenced by characteristics of both the infant and the parent, and by the nature of their dyadic interaction. Sleep–wake state organization is influenced first by homeostatic biological regulation, and later by socioemotional regulation. This report describes a feasibility study using an olfactory intervention designed to bridge the transition from physiologic to social regulation in sleep–wake state organization. A sample of 21 mother–infant dyads participated in an one year longitudinal study, after random assignment to either an experimental condition with a maternal odor-laden sleepaid, representational sleepaid (RSA) or a control condition with a neutral sleepaid, Sham Control (SC). Self-report questionnaires measured maternal psychological well-being, and video taping recorded infant sleep–wake behaviors repeatedly throughout the first year. RSA mothers reported significantly better levels of well-being throughout the year. At six and twelve months, mothers who reported more depressive feelings exhibited different nighttime interaction patterns. Infant sleep–wake state organization and sleepaid use changed significantly during the first year but were not altered by the intervention. © 1997 Michigan Association for Infant Mental Health     

The effects of noncontingent access to single- versus multiple-stimulus sets on self-injurious behavior

The automatically reinforced self-injury of a girl with autism was treated by providing noncontingent access to a single set of preferred toys during 30-min sessions. The reductive effects of the intervention waned as the session progressed. Rotating toy sets after 10 min or providing access to multiple toy sets resulted in reductions that lasted the entire 30 min.     

The Importance of Item Selection in "Knew-It-All-Along" Studies of General Knowledge

This study was designed to investigate the effects of item sampling on hindsight bias in experiments using general knowledge material. The results show that the use of random versus traditional experimenter-selected item samples can have different effects on hindsight bias. In a within-subjects study almost twice as many items in a random sample were connected with a reversed effect rather than with a traditional hindsight bias. The same items that resulted in overconfidence in foresight lead to a higher degree of hindsight bias than others. The results suggest that earlier findings of unusually large hindsight effects with general knowledge tasks may be explained by the selection of items used. No hindsight effect was found on confidence scores in a within-subjects design, but was obtained in a between-subjects design. Results suggest that the use of a within-subjects design itself can moderate hindsight bias by familiarizing subjects with the task. The study shows the importance of two conditions for decreasing the hindsight bias: (1) The use of randomly sampled items, and (2) The use of a within-subjects procedure. When these conditions were met, the "knew-it-all-along effect" was completely eliminated.     

COMPARATIVE STUDIES OF SENSORY RELATEDNESS OF ODOURS

Measures of relatedness of odours were obtained by means of two psychophysical methods and one electrophysiological technique. The psychophysical data consisted of similarity judgments and confusion measures. The electrophysiological data were based upon statistical treatment of the responses of single units in the olfactory bulb of the frog. Significant rank correlations were obtained between the results of the three methods. The significance of psychological relatedness data for the study of basic receptor processes is discussed.
