Sport Psychological Characteristics of Talented 13-Year Old Adolescents

The objective of this study was to determine whether the sport psychological profiles of talented 13-year-old sport participants differ from less talented participants. 162 grade 8 learners with a mean age of 13.2 ± 0.33 years voluntarily participated in the study. The participants were subjected to the Australian Talent Search protocol and completed the Athlete Coping Skills Inventory for Sport (ACSI-28). The group was categorize according to the median of all the tests of the talent identification protocol (TID) in a talented (TG) and a less talented group (LTG). The TG obtained higher means in all seven sport psychological characteristics: coping with adversity, peaking under pressure, goal setting, confidence, coachability and the average coping profile, concentration and freedom from worry. The results indicate that talented adolescents exhibit specific sport psychological characteristics compared to less talented adolescents.     

Facial expressions in common marmosets (Callithrix jacchus) and their use by conspecifics

Facial expressions have been studied mainly in chimpanzees and have been shown to be important social signals. In platyrrhine and strepsirrhine primates, it has been doubted that facial expressions are differentiated enough, or the species socially capable enough, for facial expressions to be part of their communication system. However, in a series of experiments presenting olfactory, auditory and visual stimuli, we found that common marmosets (Callithrix jacchus) displayed an unexpected variety of facial expressions. Especially, olfactory and auditory stimuli elicited obvious facial displays (such as disgust), some of which are reported here for the first time. We asked whether specific facial responses to food and predator-related stimuli might act as social signals to conspecifics. We recorded two contrasting facial expressions (fear and pleasure) as separate sets of video clips and then presented these to cage mates of those marmosets shown in the images, while tempting the subject with food. Results show that the expression of a fearful face on screen significantly reduced time spent near the food bowl compared to the duration when a face showing pleasure was screened. This responsiveness to a cage mate’s facial expressions suggests that the evolution of facial signals may have occurred much earlier in primate evolution than had been thought.     

Working and reference memory of pigs (Sus scrofa domesticus) in a holeboard spatial discrimination task: the influence of environmental enrichment

Interest in cognitive research in pigs is increasing, but little is known about the impact of environmental conditions on pigs’ cognitive capabilities. The present study investigated the effect of environmental enrichment on cognitive performance of pigs in a holeboard spatial task, in which they had to discriminate four baited buckets out of 16. Pigs (n = 32) were either housed in stimulus-poor, barren pens, or in larger pens enriched with rooting substrates. Pigs were subjected to 30 holeboard trials. Both working memory (WM), that is, the ratio (baited visits/total number of (re)visits to baited buckets), and reference memory (RM), that is, the ratio ((re)visits to baited buckets/total number of visits to all buckets), improved over trials. WM scores were higher in pigs from enriched pens than in pigs from barren pens. Housing did not affect RM scores. Personality type of the pigs, as assessed early in life using a backtest, did not affect WM or RM. In conclusion, housing conditions of pigs did not affect reference memory, but environmental enrichment improved working memory of pigs in a spatial discrimination task. Based on the findings of this study, we suggest that cognitive functioning of pigs may be impaired under commonly used housing conditions.     

How to become an idealist: Fichte on the transition from dogmatism to idealism

In Religion Within the Boundaries of Mere Reason, Kant claims that all human beings are originally and radically evil: they choose to adopt a ‘supreme maxim’ that gives preference to sensibility over the moral law. Because Kant thinks that all agents have a duty to develop good character, part of his task in the Religion is to explain how moral conversion is possible. Four years after Kant publishes the Religion, J. G. Fichte takes up the issue of conversion in slightly different terms: he is interested in how people he characterizes as ‘dogmatists’ (those who minimize or deny their status as free agents) become ‘idealist’ (those who recognize and exercise their freedom). Against recent interpreters, I argue that Fichte characterizes the choice to convert from dogmatism to idealism as one that is grounded in a non-rational choice. Along the way, I consider Daniel Breazeale and Allen Wood’s recent arguments to the contrary, alternative accounts of what it might mean for a conversion to count as ‘rational’, and how well my conclusion harmonizes with Fichte’s views on education.     

Combating Co‐witness contamination: Attempting to decrease the negative effects of discussion on eyewitness memory

Witnesses who discuss an event with others often incorporate misinformation encountered during the discussion into their memory of the event. Two experiments were conducted to establish whether this memory conformity also occurs in the context of an interview and whether it is possible to reduce the effect. Participants viewed a crime‐video which they then discussed with a co‐witness. Some participants were warned they may have been exposed to misinformation during the discussion before all were interviewed individually. In Experiment 1, participants made remember/know judgments about each component of their free recall, and in Experiment 2 they were asked to indicate the source of their memories. Co‐witness information was incorporated into participants' testimony, and this effect could not be significantly reduced using warnings and source‐monitoring instructions. Remember/know judgments may be useful in distinguishing ‘real’ memories from false memories. We make some recommendations regarding the interviewing of witnesses.

Alcohol intoxication and memory for events: a snapshot of alcohol myopia in a real-world drinking scenario

Alcohol typically has a detrimental impact on memory across a variety of encoding and retrieval conditions (e.g., Mintzer, 2007; Ray & Bates, 2006). No research has addressed alcohol's effect on memory for lengthy and interactive events and little has tested alcohol's effect on free recall. In this study 94 participants were randomly assigned to alcohol, placebo, or control groups and consumed drinks in a bar-lab setting while interacting with a "bartender". Immediately afterwards all participants freely recalled the bar interaction. Consistent with alcohol myopia theory, intoxicated participants only differed from placebo and control groups when recalling peripheral information. Expanding on the original hypervigilance hypothesis, placebo participants showed more conservative reporting behaviour than the alcohol or control groups by providing more uncertain and "don't know" responses. Thus, alcohol intoxication had confined effects on memory for events, supporting and extending current theories.     

Development of ASB 1: The development of antisocial behaviour in adolescents and young adults

A substantial proportion of adolescent antisocial behaviour (ASB) research has focused on identifying the chronic offender; comparatively little research has investigated developmental patterns among the general adolescent population, who account for a large proportion of ASB participation. A modified version of the Mak Self‐Report Behaviour Scale was administered to 233 (relatively advantaged) community adolescents (aged 9–17), and 193 young adults (aged 18–25). Not available in previous instruments, in addition to prevalence rates, the Adolescent ASB Scale (AASBS) accurately identifies specifically when adolescents enter, exit, and peak in their ASB participation. An earlier age of ASB participation was associated with greater frequency, severity and duration. The most noteworthy finding was a mid‐adolescent peak in ASB participation, which was shorter and more dramatic for girls. These findings provide knowledge critical for informing future research into causal explanations for the temporary and dramatic increase in adolescent ASB, and for developing more effective intervention practices with mainstream youth.     

Investigating models of affect: relationships among EEG alpha asymmetry, depression, and anxiety

The approach-withdrawal and valence-arousal models both predict that depressive and anxious profiles will be associated with relatively reduced left frontal and increased right frontal activity respectively, while the valence-arousal model also proposes a dissociation by lower and higher right parietotemporal activity, respectively. Recent work further suggests that subtypes of anxiety disorders may be characterized by distinctive patterns of activity depending on their type of arousal (anxious arousal/apprehension). The aim of this study was to investigate the relationships among nonclinical depression/anxiety and lateralized frontal/parietotemporal activity by categorizing participants (N=428) on the basis of both negative mood and alpha EEG. Key findings include: (i) greater right frontal lateralization in anxious participants, symmetrical frontal activity in depressed/comorbid, and left frontal lateralization in healthy controls; (ii) right frontal lateralization in anxious arousal participants, left frontal and right parietotemporal lateralization in anxious apprehension; (iii) bilateral increase in frontal and increased right parietotemporal activity in depressed/comorbid participants. Findings support predictions for frontal but not posterior regions. Grouping on the basis of EEG may not be reciprocally predictive of negative mood groupings, suggesting involvement of additional factors.     

It's the nature of the work: examining behavior-based sources of work-family conflict across occupations

The consequences of work-family conflict for both individuals and organizations have been well documented, and the various sources of such conflict have received substantial attention. However, the vast majority of extant research has focused on only time- and strain-based sources, largely neglecting behavior-based sources. Integrating two nationally representative databases, the authors examine 3 behavior-based antecedents of work-family conflict linked specifically to occupational work role requirements (interdependence, responsibility for others, and interpersonal conflict). Results from multilevel analysis indicate that significant variance in work-family conflict is attributable to the occupation in which someone works. Interdependence and responsibility for others predict work-family conflict, even after controlling for several time- and strain-based sources.     

Commentary on the Special Issue: Religion in the Psychology of Personality

The author comments on the special issue on religion in the psychology of personality. She focuses her discussion on the following topics: the historical tripartite theory of cognition-affection-conation; ways that family psychology and theories of language clarify the "problem" of adherence to "false realities"; the multidimensionality of personality and religion and their cultural embeddedness as illuminated in clinical assessment by way of contextual family theory (Boszormenyi-Nagy & Krasner, 1986) and the Kantor and Lehr (1975) systems theory; the role of the investigator's personality in theory and research about personality and religion; the one-sided emphasis on the empirical tradition in the psychology of religion; and the omission of the personalist tradition.
