Risk Factors for Attempting Suicide in Prisoners

We wished to examine determinants of suicidal behavior in prisoners. 903 male prisoners had a psychiatric interview which included various psychometric tests. Suicide attempters were compared with prisoners who had never attempted suicide. Significantly more of the attempters had a history of psychiatric disorder, substance abuse, a family history of suicidal behavior, convictions for violent crime, had exhibited aggressive behavior in jail, and had higher BGLHA aggression scores. A similar pattern of risk factors was found for prisoners with suicidal ideation. A lifetime history of attempting suicide, or of having suicidal ideation, is frequent in prisoners. Risk factors include family, developmental, aggression, personality, psychiatric, and substance abuse factors.     

Are Arithmetic Networks Interdependent In Number-Matching Task?

Addition and multiplication facts are retrieved from a network-like structure, as shown by data from number-matching tasks. Even if several evidences (e.g., cross-operation confusion effect) suggest that these networks are interrelated, the interdependency between addition and multiplication networks could be influenced by the type of task used (e.g., verification task). The present study aimed to investigate whether the addition and multiplication networks were interdependent or separate using a number-matching task. Eighty participants were divided in four groups. The Groups A (x, x, x) and B (+, +, +) performed the task in which only one arithmetic interference effect was implemented through three sessions (pure condition). The Groups C (x, x, +) and D (+, +, x) performed the same task in which the same arithmetic interference effect appeared in the first and second sessions, while a different arithmetic problem was presented in the last session (mixed condition). In the last session, the interference effect in the mixed condition was higher than that in the pure condition. The results argued more for an independency of addition and multiplication networks than for their interdependency.     

Spontaneous non‐verbal counting in toddlers

A wealth of studies have investigated numerical abilities in infants and in children aged 3 or above, but research on pre‐counting toddlers is sparse. Here we devised a novel version of an imitation task that was previously used to assess spontaneous focusing on numerosity (i.e. the predisposition to grasp numerical properties of the environment) to assess whether pre‐counters would spontaneously deploy sequential (item‐by‐item) enumeration and whether this ability would rely on the object tracking system (OTS) or on the approximate number system (ANS). Two‐and‐a‐half‐year‐olds watched the experimenter performing one‐by‐one insertion of ‘food tokens’ into an opaque animal puppet and then were asked to imitate the puppet‐feeding behavior. The number of tokens varied between 1 and 6 and each numerosity was presented many times to obtain a distribution of responses during imitation. Many children demonstrated attention to the numerosity of the food tokens despite the lack of any explicit cueing to the number dimension. Most notably, the response distributions centered on the target numerosities and showed the classic variability signature that is attributed to the ANS. These results are consistent with previous studies on sequential enumeration in non‐human primates and suggest that pre‐counting children are capable of sequentially updating the numerosity of non‐visible sets through additive operations and hold it in memory for reproducing the observed behavior.     

Positive Feelings at School: On the Relationships Between Students’ Character Strengths,School-Related Affect,and School Functioning

The present study was designed to examine the relationships between students’ character strengths, school-related affect, positive school functioning (i.e., motivation to learn, interest, and engagement at class), and school achievement following the “engine model of well-being” that is focusing on inputs (e.g., personality traits), processes (e.g., moods, emotions), and outcomes (e.g., engagement, accomplishments) within the context of well-being research. A sample of 196 children completed the Values in Action Inventory of Strengths for Youth, which assesses 24 character strengths, and the PANAS-C that assesses school-related positive and negative affect. Additionally, homeroom teachers rated students’ positive school functioning (i.e., motivation, engagement, and interest at school) and their overall school achievement. The character strengths of zest, love of learning, perseverance, and social intelligence showed the strongest positive correlations with school-related positive affect. Teamwork, hope, self-regulation, and love were substantially negatively correlated with school-related negative affect. Certain character strengths showed positive relationships with positive school functioning and overall school achievement. A path model, testing the “engine model of well-being”, found—additionally to direct effects—indirect relationships between character strengths and positive school functioning (through school-related positive affect), which in turn leads to higher school achievement. The presented findings show character strengths as meaningful resources in the schooling context. Character strengths emerge to be crucial for students to experience school-related positive affect, which in turn supports students’ positive school functioning and their overall school achievement. The results demonstrate the complex interplay between students’ personality traits, affect, school functioning, and achievement at school.     

Animal timing: a synthetic approach

Inspired by Spence’s seminal work on transposition, we propose a synthetic approach to understanding the temporal control of operant behavior. The approach takes as primitives the temporal generalization gradients obtained in prototypical concurrent and retrospective timing tasks and then combines them to synthetize more complex temporal performances. The approach is instantiated by the learning-to-time (LeT) model. The article is divided into three parts. In the first part, we review the basic findings concerning the generalization gradients observed in fixed-interval schedules, the peak procedure, and the temporal generalization procedure and then describe how LeT explains them. In the second part, we use LeT to derive by gradient combination the typical performances observed in mixed fixed-interval schedules, the free-operant psychophysical procedure, the temporal bisection task, and the double temporal bisection task. We also show how the model plays the role of a useful null hypothesis to examine whether temporal control in the bisection task is relative or absolute. In the third part, we identify a set of issues that must be solved to advance our understanding of temporal control, including the shape of the generalization gradients outside the range of trained stimulus durations, the nature of temporal memories, the influence of context on temporal learning, whether temporal control can be inhibitory, and whether temporal control is also relational. These issues attest to the heuristic value of a Spencean approach to temporal control.     

Learning where to feed: the use of social information in flower-visiting Pallas’ long-tongued bats (<Emphasis Type="Italic">Glossophaga soricina</Emphasis>)

Social learning is a widespread phenomenon among vertebrates that influences various patterns of behaviour and is often reported with respect to foraging behaviour. The use of social information by foraging bats was documented in insectivorous, carnivorous and frugivorous species, but there are little data whether flower-visiting nectarivorous bats (Phyllostomidae: Glossophaginae) can acquire information about food from other individuals. In this study, we conducted an experiment with a demonstrator-observer paradigm to investigate whether flower-visiting Pallas’ long-tongued bats (Glossophaga soricina) are able to socially learn novel flower positions via observation of, or interaction with, knowledgeable conspecifics. The results demonstrate that flower-visiting G. soricina are able to use social information for the location of novel flower positions and can thereby reduce energy-costly search efforts. This social transmission is explainable as a result of local enhancement; learning bats might rely on both visual and echo-acoustical perception and are likely to eavesdrop on auditory cues that are emitted by feeding conspecifics. We additionally tested the spatial memory capacity of former demonstrator bats when retrieving a learned flower position, and the results indicate that flower-visiting bats remember a learned flower position after several weeks.     

Siblings’ Understanding of Teaching in Early and Middle Childhood:‘Watch Me and You’ll Know How to Do It’

This study examined siblings’ knowledge about the teaching concept during naturalistic teaching contexts, wherein children’s communicative interactions were used as a gateway to their social understanding (Turnbull, Carpendale, & Racine, 2009). Participants included 39 sibling dyads (older age group, M_age = 6;4; younger age group, M_age = 4;5) observed for six 90-min sessions at home. Teaching episodes were identified and coded for: a) initiation of teaching (i.e., assumes role or learner requests teaching), b) knowledge states (i.e., knowledge, lack of knowledge, questioning knowledge), c) transfer of knowledge (i.e., learning), and d) teaching strategies (e.g., direct instruction). Children who assumed the teaching role referenced knowledge and questioning knowledge, whereas learners requested teaching by referencing a lack of knowledge. Firstborn learners were more likely to reference knowledge versus second-born learners who referenced a lack of knowledge. Transfer of knowledge occurred when teachers referenced knowledge. When learners referenced knowledge states, teachers were more likely to use direct instruction, demonstration, and negative feedback. Results underscore the developmental significance of sibling teaching and demonstrate a novel approach to studying children’s social understanding in the teaching context (Turnbull et al., 2009).     

Cognitive counselling intervention: treatment effectiveness in an Italian university centre

Offering counselling to students is increasingly considered as a key academic service. However, the reduction of resources allocated to Italian universities emphasises the need to assess the quality of interventions. This paper presents data reporting the effectiveness of a university counselling service. A sample of 45 undergraduate students completed a cognitive-relational intervention at a counselling service in a University in the North of Italy. The project focused on the development of reappraisal skills and problem-solving strategies to manage difficult situations. The results showed a significant pre and post-intervention reduction in self-reported psychopathological symptoms (measured with Symptoms Check List 90-Revised) as well as in general levels of distress (measured with Clinical Outcome in Routine Evaluation-Outcome Measure). A significant increase in reappraisal levels, measured with the Emotion Regulation Questionnaire, was observed, which is a focal element of the counselling intervention. There were no detectable changes in the level of suppression.     

The relationship between childhood adversity,psychiatric disorder and clinical severity: results from a multi-centre study

Although several studies have shown a clear association between childhood adversities and later development of a number of psychiatric disorders, a number of recent reports have cast doubts regarding the aetiological role played by abuse, neglect and loss, arguing that they are neither necessary nor sufficient to account for the development of subsequent psychopathology. In this study, we aimed to investigate the associations and predictive power of childhood adversities on later onset of Axis-I &-II psychiatric conditions and the impact on severity of psychiatric presentation in a large sample of patients. This cross-sectional multi-centre study evaluated patients (N = 1136) recruited in fourteen NHS psychotherapy departments in the UK. Patients were assessed using a number of rater-based questionnaires and self-rated measures. Multiple regression analyses showed that childhood experiences of loss and physical abuse were predictive of severe personality disorder and borderline personality disorder, but not of other less severe PD and Axis-I diagnoses. Sexual abuse predicted later onset of Post-traumatic Stress Disorder. In addition, we found that childhood abusive experiences were strongly associated with severity of psychiatric distress, interpersonal problems and global functioning. Having experienced two or more childhood adversities significantly increased severity of psychiatric distress, interpersonal malfunctioning and CORE scores.
