Incremental Validity of Alexithymia, Emotional Coping and Humor Style on Happiness and Psychological Well-Being

This study attempts to ascertain whether alexithymia, suppression and reappraisal coping, and humor styles account for incremental variance in happiness (Lyubomirsky’s scale) and psychological well-being (Ryff’s scale), after controlling for Big Five traits and emotional positivity ratio of previous day’s mood. A total of 355 psychology undergraduates (72 % women) responded to measures of each construct, and two hierarchical multiple regressions were carried out for happiness and psychological well-being. The Big Five were entered in the first regression block, alexithymia was entered in a second block, and affiliative, self-enhancing, aggressive and self-defeating humor style, reappraisal and suppression coping were entered in the third block, and previous day’s mood in the last step. Alexithymia accounted for a small proportion of variance in psychological well-being, controlling for the Big Five traits. Suppression and affiliative, self-enhancing and self-defeating humor explained a complementary amount of variance in happiness and psychological well-being, controlling for the previous day’s mood, confirming the association of emotional regulation and affect with judgments of happiness and well-being. Taking into account humor and suppression, the multivariate association of alexithymia disappears. Results suggest that low suppression, low self-critical use of humor and affiliative humor are correlates of psychological well-being, whereas self-enhancing humor and low suppression are correlates of happiness, playing a mediational role between personality traits and well-being.     

Test sensitivity is important for detecting variability in pointing comprehension in canines

Several articles have been recently published on dogs’ (Canis familiaris) performance in two-way object choice experiments in which subjects had to find hidden food by utilizing human pointing. The interpretation of results has led to a vivid theoretical debate about the cognitive background of human gestural signal understanding in dogs, despite the fact that many important details of the testing method have not yet been standardized. We report three experiments that aim to reveal how some procedural differences influence adult companion dogs’ performance in these tests. Utilizing a large sample in Experiment 1, we provide evidence that neither the keeping conditions (garden/house) nor the location of the testing (outdoor/indoor) affect a dogs’ performance. In Experiment 2, we compare dogs’ performance using three different types of pointing gestures. Dogs’ performance varied between momentary distal and momentary cross-pointing but “low” and “high” performer dogs chose uniformly better than chance level if they responded to sustained pointing gestures with reinforcement (food reward and a clicking sound; “clicker pointing”). In Experiment 3, we show that single features of the aforementioned “clicker pointing” method can slightly improve dogs’ success rate if they were added one by one to the momentary distal pointing method. These results provide evidence that although companion dogs show a robust performance at different testing locations regardless of their keeping conditions, the exact execution of the human gesture and additional reinforcement techniques have substantial effect on the outcomes. Consequently, researchers should standardize their methodology before engaging in debates on the comparative aspects of socio-cognitive skills because the procedures they utilize may differ in sensitivity for detecting differences.     

Part set cuing in older adults: further evidence of intact forgetting in aging

The aim of this study was to look at the effect of aging on part set cuing while equating for baseline performance in episodic memory. Younger and older participants listened to three different word lists, each containing 24 words relating to a particular category. During recall, 0, 33, or 66% of the items presented in the learning phase were re-presented as cues. The results showed that recall of the never cued items was equally impaired by the presence of cues in younger and older adults, thus showing equivalent part set cuing effects in both groups. These results parallel previous findings showing equivalent inhibitory effects in younger and older adults with tasks that do not require executive control and provide additional support to previous studies challenging the view that frontal/executive processes play a major role in part set cuing.     

Social skills in women with Turner Syndrome

The aim of this study was to evaluate the performance of a group of women with Turner Syndrome (TS) in interpersonal situations where several social skills were required, and to compare the results with unaffected sisters. Fifty-two TS females aged 15-35 years and 33 sisters aged 16-43 were evaluated using Del-Prette Social Skills Inventory (SSI) and individual interviews. Thirty mothers to subjects and sisters answered questionnaires. It was found that TS girls' performance in SSI was as good as their sisters' and even better in meeting new people and facing unknown situations (p = 0.020). Older TS women scored better than younger ones, differently from their sisters. There were no significant correlations between total score of TS women and their age at diagnosis, time of follow-up and height z-score. Mothers reported having more problems with TS girls than with sisters. Although TS girls demonstrated having social difficulties, just a few of them spontaneously complained about interpersonal problems in the interview. Results suggest that social difficulties may not cause TS girls major problems nor make them unhappy with their social lives, and/or TS girls may not be able to perceive their own difficulties. Good performance in SSI also suggests that TS girls can identify adequate skills in presented situations and answer in a way to obtain good scores, but they may not necessarily use their skills due to other factors like anxiety and shyness. They may also have a tendency to answer SSI in a way they consider socially desirable, masking their real difficulties.     

Assessment of affect integration: validation of the affect consciousness construct

Affect integration, or the capacity to utilize the motivational and signal properties of affect for personal adjustment, is assumed to be an important aspect of psychological health and functioning. Affect integration has been operationalized through the affect consciousness (AC) construct as degrees of awareness, tolerance, nonverbal expression, and conceptual expression of nine discrete affects. A semistructured Affect Consciousness Interview (ACI) and separate Affect Consciousness Scales (ACSs) have been developed to specifically assess these aspects of affect integration. This study explored the construct validity of AC in a Norwegian clinical sample including estimates of reliability and assessment of structure by factor analyses. External validity issues were addressed by examining the relationships between scores on the ACSs and self-rated symptom- and interpersonal problem measures as well as independent, observer-based ratings of personality disorder criteria and the Global Assessment of Functioning (GAF) scale from the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994).     

A method for quantifying focused versus overview behavior in AOI sequences

We present a new measure for evaluating focused versus overview eye movement behavior in a stimulus divided by areas of interest. The measure can be used for overall data, as well as data over time. Using data from an ongoing project with mathematical problem solving, we describe how to calculate the measure and how to carry out a statistical evaluation of the results.     

Identifying the processes underpinning anticipation and decision-making in a dynamic time-constrained task

A novel, representative task was used to examine skill-based differences in the perceptual and cognitive processes underlying performance on a dynamic, externally paced task. Skilled and less skilled soccer players were required to move and interact with life-size, action sequences involving 11 versus 11 soccer situations filmed from the perspective of a central defender in soccer. The ability of participants to anticipate the intentions of their opponents and to make decisions about how they should respond was measured across two separate experiments. In Experiment 1, visual search behaviors were examined using an eye-movement registration system. In Experiment 2, retrospective verbal reports of thinking were gathered from a new sample of skilled and less skilled participants. Skilled participants were more accurate than less skilled participants at anticipating the intentions of opponents and in deciding on an appropriate course of action. The skilled players employed a search strategy involving more fixations of shorter duration in a different sequential order and toward more disparate and informative locations in the display when compared with the less skilled counterparts. The skilled players generated a greater number of verbal report statements with a higher proportion of evaluation, prediction, and planning statements than the less skilled players, suggesting they employed more complex domain-specific memory representations to solve the task. Theoretical, methodological, and practical implications are discussed.     

Why are auditory novels distracting? Contrasting the roles of novelty, violation of expectation and stimulus change

Past studies show that novel auditory stimuli, presented in the context of an otherwise repeated sound, capture participants’ attention away from a focal task, resulting in measurable behavioral distraction. Novel sounds are traditionally defined as rare and unexpected but past studies have not sought to disentangle these concepts directly. Using a cross-modal oddball task, we contrasted these aspects orthogonally by manipulating the base rate and conditional probabilities of sound events. We report for the first time that behavioral distraction does not result from a sound’s novelty per se but from the violation of the cognitive system’s expectation based on the learning of conditional probabilities and, to some extent, the occurrence of a perceptual change from one sound to another.     

Utility of a statistical model of cognitive styles in attention deficit hyperactivity disorder

The purpose of this study was to determine the best statistical model of cognitive styles, based on the MFFT-20, CEFT and Stroop tests to predict attention deficit hyperactivity disorder (ADHD), analyzing the validity of the model for the diagnosis of the disease. We studied 100 ADHD cases (DSM-IV criteria) and 100 controls, age ranging between 7 and 11 years. Controls were randomly recruited and matched in age, gender and sociodemographic area with ADHD cases. On average, ADHD cases showed more impulsiveness (d: 1.28), less cognitive flexibility (d: 0.91) and more field dependence (d: 1.62) than controls. The logistic regression model that predicts ADHD best is made up of age, CEFT, MFFT-20 and Stroop tests and the formula derived from the model shows 85% sensitivity and 85% specificity for ADHD, regarding the DSM-IV criteria as the standard. The statistical model of cognitive styles presents valid indicators to diagnose ADHD, contributing to an increase in the objectivity of its analysis.
