Impaired task switching performance in children with dyslexia but not in children with autism

Problems with cognitive control in both autism and dyslexia have already been reported in different studies. The present study specifically examined task-switching performance in children with autism and dyslexia. For this purpose, a multiple-trial paradigm was used with cues for colour- and shape-matching tasks presented before a run of trials. The cue could imply a task switch (when the cue changed the task) or a task repetition (when the cue did not change the task). Both reaction times and error rates were measured for switching, restarting, and general task performance. Participants were children with autism (24) and with dyslexia (25) and healthy controls (27) with normal IQ and ages from 12 to 18 years. The main finding was that while similar switching performance was observed between children with autism and the healthy controls, children with dyslexia showed a significant switch-specific delay relative to both healthy controls and children with autism. Furthermore, no deficit in restarting performance was observed for any of the two patient groups. Finally, additional evidence is provided for a more general deficit in information processing in dyslexia. Our data suggest that children with autism are able to switch between tasks in a similar way as do normally developing children as long as the tasks are unambiguously specified. Furthermore, the data imply switch-specific deficits in dyslexia additionally to the deficits in general information processing already reported in the literature. The implications of our data are further discussed in relation to the interpretation of the Wisconsin Card Sorting Test.     

Understanding the role of executive control in the Implicit Association Test: Why flexible people have small IAT effects

The goal of the present research was to investigate the role of three central-executive functions—switching of mental sets, inhibition of prepotent responses, and simultaneous storage and processing (i.e., working-memory capacity)—in accounting for method variance in the Implicit Association Test (IAT). In two studies, several IATs with unrelated contents were administered along with a battery of central-executive tasks, with multiple tasks tapping each of the above executive functions. Method variance was found to be related to the switching factor, but not to the inhibition factor. There was also evidence for a small independent contribution of the working-memory capacity factor. The findings constrain process accounts of the IAT, lending support to an account in terms of task-set switching, and they have consequences for applications.     

Psychological Hardiness and Adjustment to Life Events in Adulthood

Data were collected from 88 persons who had lost their jobs and 227 persons whose youngest child had left home to explore the impact of psychological hardiness on personal distress, adjustment, and coping strategies. Analyses controlling for numerous sociodemographic factors as well as NEO Neuroticism and Extroversion suggested that the interaction between overall hardiness and the experience of differential life events influenced the use of planful problem solving and positive reappraisal as coping mechanisms, as well as influencing levels of positive affect. In addition, a main effect for overall hardiness on several coping strategies, positive affect, and life satisfaction was obtained. Findings also suggested that job loss was a more stressful experience for adults in this study than was the empty nest. These data indicate that hardiness may mediate responses to life events that differ in terms of their predictability and anticipatory nature.     

A Longitudinal Analysis of the Role of Biopsychosocial Factors in Predicting Body Change Strategies Among Adolescent Boys

In this study we examined the role of biopsychosocial factors on adolescent boys' body modification strategies over an 8-month period. Participants were 434 adolescent boys aged between 11 and 16 years. The majority of respondents were from Anglo-Australian backgrounds (83%); the others were from Asian and European non-English-speaking backgrounds. The results indicated a consistent relationship between perceived encouragement to engage in body change strategies and increases in adolescents' body modification strategies, including muscle gain, weight gain, and weight loss. In addition, poor parent relations, being younger, and higher scores on the pubertal development scale predicted increased use of food supplements. However, the stability of the body modification strategies and the examined variables over the 8-month period were low. Further studies are needed to examine the stability of adolescent self-perceptions over both longer and shorter periods. Moreover, researchers need to include other factors that may be more relevant for adolescent boys (e.g., involvement in sports).     

Anaesthesia or psychotherapy: Eradicating thoughts or working them through

The author presents two sessions from the analysis of a depressive narcissistic doctor, which are characterised by a mixture of co-operation and pseudo-co-operation. The dialogue is in parts intellectualised, complicated, lifeless and schizoid. Points at which the patient shows surprising insights are then partly denigrated by him, on the basis that change is not to be expected. Semi-lifeless contact assists the defensive claustrophobia that he experiences in meaningful contact. It becomes very clear that he is then afraid of entering into an openly aggressive conflict that entails the existential threat of object loss. However, this has so far been avoided. The secret pleasure in an anal-narcissistic, sadomasochistic addiction to doubt persists in the partial denigration. The patient's artificially maintained self-doubt and doubt of the object reinforce a genuine confusion that consists in never knowing exactly what lies behind the helpful and needed object.     

Executive functioning profiles in elite volleyball athletes: Preliminary results by a sport-specific task switching protocol

Executive functions (EF) are crucial for the athletes’ success, and they are even more essential in open skill sports (e.g. volleyball and football). In these sports, due to continuously changing conditions, goal-directed behaviours need to be repeatedly adjusted and corrected. One of the most important EF is the ability to continuously switch between two different tasks being required in a random sequence. We used a task-switching protocol in elite volleyball athletes, usually playing different roles, with the aim of evaluating if each role is characterized by specific switching abilities. On the basis of the specific competences requested by the game, thirty-six elite volleyball athletes were assigned to three groups: Strikers, Defenders and Mixed. Each player completed a customized sport-specific task-switching paradigm. Data evidenced that each role has specific characteristics. In Reaction Times, the Strikers were the fastest to answer to stimuli, while the Defender group provided a worse performance, particularly when defensive actions, that probably require more cognitive elaboration, had to be processed. Different effects emerged by the Errors. In fact, the Mixed group, which was the one with more expertise, appeared to be more accurate in the responses.Although preliminary, these results showed a minimal degree of cognitive flexibility for highly specialized Strikers and a maximum level for Mixed, allowing thus to highlight specific profiles of athletes. Data observed indicate the possibility to develop a test assessing the executive domain during the recruitment in a team, revealing a useful tool for choosing the most suitable role.     

Efficient nonparametric approaches for estimating the operating characteristics of discrete item responses

Rationale and the actual procedures of two nonparametric approaches, called Bivariate P.D.F. Approach and Conditional P.D.F. Approach, for estimating the operating characteristic of a discrete item response, or the conditional probability, given latent trait, that the examinee's response be that specific response, are introduced and discussed. These methods are featured by the facts that: (a) estimation is made without assuming any mathematical forms, and (b) it is based upon a relatively small sample of several hundred to a few thousand examinees.Some examples of the results obtained by the Simple Sum Procedure and the Differential Weight Procedure of the Conditional P.D.F. Approach are given, using simulated data. The usefulness of these nonparametric methods is also discussed.This research was mostly supported by the Office of Naval Research (N00014-77-C-0360, N00014-81-C-0569, N00014-87-K-0320, N00014-90-J-1456).     

Does Religious Belief Matter for Grief and Death Anxiety? Experimental Philosophy Meets Psychology of Religion

It is commonly reasoned that religious belief moderates death anxiety and aids in coping with loss. However, a philosophical perspective known as meta‐atheism includes the claim that avowed religious believers grieve deaths and experience death anxiety as intensely as avowed atheists. Thus, we report a study comparing religious believers and nonbelievers on measures of death anxiety and grief. We further investigated the relationships between certain religious beliefs (views of God, afterlife belief, religious orientation) and death anxiety, as well as both painful grief reactions and grief‐related growth. We surveyed 101 participants across the United States, ranging in age (19 to 57), education, and ethnicity. Participants avowing some form of religious belief, in comparison to those not, did not demonstrate lower levels of death anxiety. They did, however, display higher levels of a certain type of death acceptance. Additionally, those professing belief reported less grief and greater growth in response to loss. Greater afterlife belief was not associated with less grief; however, it was associated with both greater grief‐related growth and lower death anxiety.     

Self-determination and motivation for bariatric surgery: a qualitative study

This study examined how obese individuals acquire their motivation to undergo weight loss surgery and characterized the motivations within the framework of the self-determination theory (SDT). Participants expecting to have bariatric surgery were recruited and participated in semi-structured interviews. Interview accounts characterized different types of motivation for individuals seeking surgical weight loss treatments on the SDT continuum of relative autonomy. This study demonstrated that the more one’s motivation was internally regulated, related to one’s personal life and supported for competency, the more personal and hopeful were the anecdotes participants mentioned in accounts, thus the more positive the surgical outcomes were anticipated. Study limitations and future research were discussed as was the need for a systematic scheme to categorize types of motivation within the SDT, a longitudinal approach to measure actual weight loss outcomes based on the patient’s pre-surgical motivation, and a further investigation with a larger sample size and balanced gender ratio. Practical implications of the study findings were also discussed as a novel strategy to internalize bariatric patients’ motivation, further helping to improve their long-term quality of life post-surgery.     

Chinese are more loss averse than British

This research investigates how culture might influence loss aversion. Chinese were expected to be more loss averse than British because of cultural differences in regulatory focus. Study 1 reveals that compared with British participants, Chinese participants were less likely to give up gifts they had received in exchange for new gifts. In Study 2, Chinese and British participants imagined buying a computer which either had a high specification and a high price tag (high reference), or a basic specification and a low price tag (low reference). Participants were informed that the (reference) computer was unavailable, and they had to choose between two available computers, which were both cheaper and less powerful than the high reference computer, and more expensive and more powerful than the low reference computer. The results reveal that the difference in price tag between the two available computers had a bigger impact on Chinese buying decisions than on British buying decisions when it was viewed as a loss. Furthermore, both promotion focus and prevention focus mediated the influence of culture on buying decisions in the low reference condition. No cross‐cultural difference was found in the high reference condition.
