Indexing the approximate number system

Much recent research attention has focused on understanding individual differences in the approximate number system, a cognitive system believed to underlie human mathematical competence. To date researchers have used four main indices of ANS acuity, and have typically assumed that they measure similar properties. Here we report a study which questions this assumption. We demonstrate that the numerical ratio effect has poor test–retest reliability and that it does not relate to either Weber fractions or accuracy on nonsymbolic comparison tasks. Furthermore, we show that Weber fractions follow a strongly skewed distribution and that they have lower test–retest reliability than a simple accuracy measure. We conclude by arguing that in the future researchers interested in indexing individual differences in ANS acuity should use accuracy figures, not Weber fractions or numerical ratio effects.     

Validation of an Italian version of the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3) on adolescent girls

The present study used exploratory factor analysis (EFA) to investigate the factor structure of an Italian version of the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3) with a sample of 598 adolescent girls. Results of EFA indicated a four-factor structure: Information, Pressures, Internalization-General, and Internalization-Athlete. Factor loadings confirmed the original structure of the scale, except for one item. As expected, the four factors appeared to be slightly correlated. Cronbach's alphas for the four subscales were uniformly high: Information = .91, Pressures = .91, Internalization-General = .94, Internalization-Athlete = .84. Convergent validity of this Italian version of the SATAQ-3 was found to be good. SATAQ-3 seems useful to measure different aspects of societal influences on body image in Italian contexts. Future studies could subject SATAQ-3 to a confirmatory factor analysis in order to confirm the adequate fit of the model according to conventional criteria.     

Suicide Clusters: A Review of Risk Factors and Mechanisms

Suicide clusters, although uncommon, cause great concern in the communities in which they occur. We searched the world literature on suicide clusters and describe the risk factors and proposed psychological mechanisms underlying the spatio‐temporal clustering of suicides (point clusters). Potential risk factors include male gender, being an adolescent or young adult, drug or alcohol abuse, and past history of self‐harm. However, the majority of studies lack methodological rigor. Many different psychological mechanisms are described, including contagion, imitation, suggestion, learning, and assortative relating, but supporting empirical evidence is generally lacking. More scientifically rigorous studies are needed to improve understanding of suicide clusters.     

Suicidal Intent and Method of Self‐Harm: A Large‐scale Study of Self‐Harm Patients Presenting to a General Hospital

Data from the Oxford Monitoring System for Attempted Suicide (2004–2011) were used to study hospital presentations for self‐harm in which Suicidal Intent Scale (SIS) scores were obtained (N = 4,840). Regression of medians was used to control for the confounding effect of age and gender. Higher estimated median SIS scores were associated with increasing age, male gender, self‐poisoning versus self‐injury, multiple methods of self‐harm versus self‐injury alone, use of gas (mainly carbon monoxide), dangerous methods of self‐injury (including hanging, gunshot), and use of alcohol as part of the act. For self‐poisoning patients, there was a correlation between the number of tablets taken and the total SIS score. Compared with self‐poisoning with paracetamol and paracetamol‐containing compounds, self‐poisoning with antipsychotics was associated with a lower median SIS score while antidepressants had the same estimated median as paracetamol. Use of alcohol within 6 hours of self‐harm was associated with lower SIS scores. In conclusion, certain methods of self‐harm, particularly dangerous methods of self‐injury and self‐poisoning with gas, were associated with high intent and should alert clinicians to potential higher risk of suicide. However, apart from use of gas, suicidal intent cannot be inferred from type of drugs used for self‐poisoning.     

Catching more than pocket monsters: Pokémon Go's social and psychological effects on players

ABSTRACT

The augmented reality mobile game Pokémon Go has reached unprecedented popularity since its release in 2016. The game has received intense media attention, but scientific inquiry into its popularity and the effects of play are in the early stages. Previous work has used secondary data or simple correlational analysis to draw early conclusions. A seven-day diary study was conducted to investigate potential health, psychological, and social outcomes of daily gameplay. Daily time spent playing Pokémon Go was related to higher scores of life satisfaction, vitality, and greater social interactions and conversation with both friends and strangers, but not with increased daily exercise. Increased total gameplay across the week was associated with increased interaction and conversations along with more exercise. Future directions for this unique type of game along with the need for theoretical development for unique style of games are discussed.     

Dissatisfied psychotherapy patients: A tentative conceptual model grounded in the participants' view

Usually, between 5% and 20% of psychotherapy patients are dissatisfied with their treatments. This naturalistic study explores seven clearly dissatisfied patients' view of the therapeutic process and outcome. Interviews at termination of psychoanalytic psychotherapy and at a 1.5-year follow-up were analysed to create a tentative conceptual model of patient dissatisfaction using grounded theory approach. At the core of the model is an experience of abandonment by a therapist felt to be insufficiently flexible, a therapy lacking intensity, and links missing between therapy and everyday life. Dissatisfied patients lacked confidence in their relationship with the therapist, described their therapists in negative terms and concluded that their therapies lacked direction. They wanted more response from the therapist. Paying greater attention to the patient's emerging dissatisfaction may prevent lasting disappointment, unnecessary continuation of fruitless treatment, and probably increase efficiency.
