Egg incubation effects generate positive correlations between size,speed and learning ability in young lizards

Previous studies have suggested that body size and locomotor performance are targets of Darwinian selection in reptiles. However, much of the variation in these traits may derive from phenotypically plastic responses to incubation temperature, rather than from underlying genetic variation. Intriguingly, incubation temperature may also influence cognitive traits such as learning ability. Therefore, we might expect correlations between a reptile’s size, locomotor speed and learning ability either due to selection on all of these traits or due to environmental effects during egg incubation. In the present study, we incubated lizard eggs (Scincidae: Bassiana duperreyi) under ‘hot’ and ‘cold’ thermal regimes and then assessed differences in hatchling body size, running speed and learning ability. We measured learning ability using a Y-maze and a food reward. We found high correlations between size, speed and learning ability, using two different metrics to quantify learning (time to solution, and directness of route), and showed that environmental effects (incubation temperature) cause these correlations. If widespread, such correlations challenge any simple interpretation of fitness advantages due to body size or speed within a population; for example, survivors may be larger and faster than nonsurvivors because of differences in learning ability, not because of their size or speed.     

Personality and aesthetic preference in Spain and England: two studies relating sensation seeking and openness to experience to liking for paintings and music

In two studies, one employing Spanish students and the other English students, questionnaire measures of Sensation Seeking and Openness to Experience were correlated with liking for major music types, several short music excerpts, and eight categories of painting (presented as slides). Inter‐correlations between music preference measures, painting preference, and personality are reported. In both samples, the Sensation Seeking Scale (Form V) and, particularly, the Experience Seeking sub‐scale were associated with a factor contrasting liking for ‘hard rock’ music and ‘violent–abstract’ art with liking for ‘neutral–realistic’ art and ‘easy listening’ music. Several substantial relationships between aesthetics measures and Openness to Experience (from the NEO‐PI‐R) were also found, though mostly in the English sample. The results reinforce the view that personality dimensions such as Sensation Seeking and Openness are important influences on aesthetic judgment. Copyright © 2000 John Wiley & Sons, Ltd.     

Personality characteristics of sheep and goats

A great deal of parapsychological research has investigated the effect, upon extrasensory perception (ESP), of the so-called ‘sheep-goat variable’ (SGV), that is, belief in the existence of ESP, either in the abstract or with respect to one's own psychic ability. However, very little purely psychological research has examined the question of possible personality differences between ‘sheep’ (the ‘believers’) and ‘goats’ (the ‘disbelievers’). Personality factors are important both as potentially confounding variables, and as independent predictors of psi-scoring which could be used in combination with the SGV.This paper reports two sets of experiments of the pilot-confirmation type: a grand total of 552 subjects were administered various personality tests plus one or other of two ‘sheep-goat scales’. Replicated results indicated that the SGV was related to extraversion-introversion and to conservatism-radicalism: sheep tend to be more extraverted and more conservative than goats, who tend towards introversion and intellectual skepticism.

Sex,Power, and Money: Prediction from the Dark Triad and Honesty–Humility

Data were collected from two undergraduate student samples to examine (i) the relations of the ‘Dark Triad’ variables (Machiavellianism, Psychopathy, and Narcissism) with the HEXACO personality dimensions, as well as (ii) the ability of the aforementioned characteristics and of the Big Five personality factors to predict outcome variables related to sex, power, and money. Results indicated that the common variance of the Dark Triad was very highly correlated with low Honesty–Humility and that the unique variance of each of the Dark Triad variables also showed theoretically meaningful relations with the other five HEXACO factors. Furthermore, the Dark Triad and Honesty–Humility were strong predictors of three domains of outcome variables—Sex (short‐term mating tendencies and sexual quid pro quos), Power (Social Dominance Orientation and desire for power), and Money (conspicuous consumption and materialism)—that were not well predicted by the dimensions of the Big Five.

Digit ratio (2D:4D) and Cattell's personality traits

The ratio between second and fourth finger (2D:4D) is sexually dimorphic; it is lower in men than in women. Studies using broad personality domains yielded correlations of 2D:4D with neuroticism, extraversion or agreeableness, but the obtained results have been inconsistent. We correlated 2D:4D of 184 women and 101 men with their scores in Cattell's 16 Personality Factor (16PF) Questionnaire. We found women with a higher (more ‘feminine’) right hand 2D:4D to score lower in emotional stability and social boldness and higher in privateness. Mediator analysis showed emotional stability to be probably primarily correlated with 2D:4D and to act as a mediator between 2D:4D and social boldness. Privateness appears to be mediated by an even more complex path. We discuss the usefulness of primary‐level personality questionnaires and mediator analyses in the investigation of psycho‐morphological associations. Copyright © 2007 John Wiley & Sons, Ltd.     

The Genetic Overlap and Distinctiveness of Flourishing and the Big Five Personality Traits

The growing evidence that subjective well-being (SWB) produces an array of beneficial outcomes has increased requests for recommendations on how to promote it. Evidence that all of SWB’s genetic variance overlaps with personality led to the strong claim that it is a ‘personality thing’ and that personality is the strongest predictor of SWB. However, studies do not include a comprehensive assessment that reflects eudaimonic as well as hedonic SWB. We revisit the question of SWB’s complete overlap with personality employing the tripartite model—emotional, psychological, and social—of SWB that, together, reflect Keyes’ (2002) model of flourishing. Data are from the Midlife in the United States national sample of 1,386 twins. Analyses were done using Mx to test Cholesky decomposition models and a two latent factor common pathway model. One-third of the total (72 %) heritability of flourishing and 40 % of its environmental variability are distinct from the big-five personality traits. We also find a low phenotypic association (mean r = .22) between the three dimensions of SWB and big-five personality traits despite substantial shared genetic etiology. In addition to non-trivial amounts of distinctive genetic and environmental variance and low phenotypic correlation, we point to limited investigation of reciprocal causation of SWB and personality. Psychologist should not yet conclude that SWB is a ‘personality thing’ anymore than personality might be a ‘well-being thing’.     

Phenotypes of sleeplessness: stressing the need for psychodiagnostics in the assessment of insomnia

Insomnia is a too general term for various subtypes that might have different etiologies and therefore require different types of treatment. In this explorative study we used cluster analysis to distinguish different phenotypes in 218 patients with insomnia, taking into account several factors including sleep variables and characteristics related to personality and psychiatric comorbidity. Three clusters emerged from the analysis. The ‘moderate insomnia with low psychopathology’-cluster was characterized by relatively normal personality traits, as well as normal levels of anxiety and depressive symptoms in the presence of moderate insomnia severity. The ‘severe insomnia with moderate psychopathology’-cluster showed relatively high scores on the Insomnia Severity Index and scores on the sleep log that were indicative for severe insomnia. Anxiety and depressive symptoms were slightly above the cut-off and they were characterized by below average self-sufficiency and less goal-directed behavior. The ‘early onset insomnia with high psychopathology’-cluster showed a much younger age and earlier insomnia onset than the other two groups. Anxiety and depressive symptoms were well above the cut-off score and the group consisted of a higher percentage of subjects with comorbid psychiatric disorders. This cluster showed a ‘typical psychiatric’ personality profile. Our findings stress the need for psychodiagnostic procedures next to a sleep-related diagnostic approach, especially in the younger insomnia patients. Specific treatment suggestions are given based on the three phenotypes.     

Forensic neuropsychiatric aspects of epilepsy

Epilepsy may be associated with automatisms that are classed as ‘insane ‘as they are deemed to have originated within the mind. ‘Sane automatism’ is said to occur from external factors, such as physical trauma, while ‘insane automatism’ is said to be innate to the individual experiencing them. To claim automatism within the context of a criminal matter requires a detailed evaluation of the behavior demonstrated and a questioning of the volitional and purposeful nature of this behavior. It is insufficient to rely upon past behavior in association with these seizures to justify the defense of automatism within a specific event. Epilepsy is often considered to be associated with an increase in violence. Proper epidemiological research, both in long-term, large population control studies and hospital-based studies, has suggested that epilepsy, per se, is not associated with an increase in violence when compared to the population at large and controlled for other familial and environmental factors.     

An alternative multi‐language structure for personality attributes

A scientific taxonomy of human personality attributes should optimally be based on studies from multiple languages and cultures. Study 1 demonstrates convergence between seven‐factor structures found in previous studies of Filipino and Hebrew languages. Study 2 shows that this ‘Multi‐Language Seven’ (ML7) factor model overlaps partially with the Big Five model, but includes four rather than three affective–interpersonal factors, replicates in American English lexical data nearly as well as the Big Five, and has close correspondences to the structure upon which two Italian lexical studies have converged. Correlates were used to clarify interpretation of ML7 factors labelled Gregariousness, Self‐Assurance, Even Temper ‘versus Temperamentalness’, Concern for Others, Conscientiousness, Originality/Virtuosity, and Negative Valence ‘or Social Unacceptability’. These studies indicate the viability of a lexically derived ‘etic’ alternative to the Big Five. Copyright © 2003 John Wiley & Sons, Ltd.     

The learning theory model of neurosis—A new approach

This paper is concerned with the development of a learning theory model of neurosis which would not be susceptible to the many criticisms which can be made of former models. Two widely favoured models—those of Freud and Skinner—are rejected because they are either non-falsifiable or tautological. The Watson and Mowrer models are rejected because they have been experimentally invalidated. The model here suggested differs from previous ones in several important respects. In the first place, it replaces the classical law of extinction by a more modern version which allows for incubation (enhancement) effects of exposure to CS-only stimuli, as well as for extinction effects. In the second place, the model emphasizes the importance of individual differences, and suggests precise relations between personality and the conditioning of neurotic behaviours. In the third place, the model lays stress on innate fear patterns and ‘preparedness’ as important factors in the genesis of conditioned fear responses. In the fourth place, the concept of ‘pain’ in the classical animal literature, and its use in creating models of neurosis, is supplemented by other concepts (‘frustrative non-reward’, ‘approach-avoidance’ conflict) which are more relevant to human neurosis. In the fifth place, and most important. the notion of ‘traumatic’, single-trial conditioning is abandoned, and a new theory based on incubation is proposed. It is suggested that the new theory is more adequate than previous ones to account for the known facts of human neurosis, and that it suggests novel types of experiment in both the animal and human fields which can be used to test its adequacy.     

Auditory distraction from low‐intensity noise: a review of the consequences for learning and workplace environments

The ‘irrelevant sound effect’ in short‐term memory is commonly believed to entail a number of direct consequences for cognitive performance in the office and other workplaces (e.g. S. P. Banbury, S. Tremblay, W. J. Macken, & D. M. Jones, 2001 ). It may also help to identify what types of sound are most suitable as auditory warning signals. However, the conclusions drawn are based primarily upon evidence from a single task (serial recall) and a single population (young adults). This evidence is reconsidered from the standpoint of different worker populations confronted with common workplace tasks and auditory environments. Recommendations are put forward for factors to be considered when assessing the impact of auditory distraction in the workplace. Copyright © 2005 John Wiley & Sons, Ltd.     

Beyond the broom cupboard: teaching assistants’ reflections upon the wider impact of their specialist dyslexia training

Whilst the government-commissioned Rose Report (2009) on provision and support for dyslexic learners in England called for the deployment of more specialist dyslexia teachers in mainstream schools, the reality seems to be that the job of teaching literacy to children with dyslexia is falling to teaching assistants (TAs). As a result, specialist training courses for TAs have been developed in England. Using the Coldwell and Simkins Training Impact Framework, the present study examines TAs participants’ perceptions of the impact of two such local authority-based training programmes, not just in terms of the impact upon their individual practice, but also in terms of their perceptions of the wider impact of their status as a trained ‘expert’ upon their schools’ policies, culture and practice. ‘Enabling’ and ‘blocking’ factors influencing this wider impact are identified, and implications for the deployment of specialist TAs and the design of their training courses are discussed.     

Testing the properties of the triarchic model of psychopathy in a community sample: Self‐reported trait aggression and drug consumption associations

The triarchic model of psychopathy encompasses different conceptions of psychopathic personality characterized by three phenotypic components: boldness, disinhibition, and meanness. Psychopathy is a complex construct at both emotional and behavioral level. The aim of this study was to determine the core elements of psychopathic personality in a community sample and analyze the relation between these elements and other personality traits such as aggression, and certain specific behavioral manifestations such as substance use. The study sample comprised 1,159 participants aged between 17 and 74 years, who were administered the Triarchic Psychopathy Questionnaire, the Impulsive‐Premeditated Aggression Scale, and the Aggression Questionnaire. The results show that the constructs of meanness and disinhibition are more highly associated with different forms of both impulsive and premeditated aggression. Furthermore, men scored higher on all three components of the triarchic model compared to women. Finally, higher substance use (tobacco and drugs) was associated with higher scores in meanness, boldness, and disinhibition. These findings demonstrate the importance of assessing psychopathy in a community sample, and the detection of possible risk factors for the disorder.     

Paralympics and the Fabrication of ‘Freak Shows’: On Aesthetics and Abjection in Sport

Two years before the opening of the Paralympic Games in London in 2012, the British TV network Channel 4 launched a campaign called Freaks of Nature. As part of the campaign they produced the short film Meet the Superhumans by director Tom Tagholm. The film became an immediate success, but was also criticised for portraying the Paralympians as ‘freaks’ and for reducing the Paralympics to a ‘freak show’. But was it wrong to describe the Paralympics as a ‘freak show’? Is there even a point of using the term ‘freak show’ in relation to sports? There might be, and that is what I am discussing in this paper. To be more specific, I am proposing that the term ‘freak show’ can challenge and destabilise common aesthetic views in sport, simply by the adding of abject dimensions to the athletic performances. From this one can claim that the Paralympics reconnects to the freak show-tradition of the past. And that, in itself, can have a moral and political impact.     

Isolation

This paper reflects upon Winnicott’s term “the isolate” or “incommunicado self,” which must remain hidden for personality development to proceed satisfactorily. Paradoxically, the (of necessity) concealed isolate or True Self accedes to the personality’s dependence on an object for this development to take place. The impact of trauma on the isolate and the formation of pathological isolation are considered. The outcome of analysis with a traumatized person is contingent upon the type of narcissistic defenses employed to protect the isolate that has experienced impingement and exposure, with the adverse consequences for personality development this entails. A particular form of narcissistic withdrawal into what Green terms “deobjectalization” and “negative narcissism” is examined as a way in which the death instinct can infuse the personality’s defense of the isolate, limiting radically what may be analyzed. A clinical example is given.     

Food approach conditioning and discrimination learning using sound cues in benthic sharks

The marine environment is filled with biotic and abiotic sounds. Some of these sounds predict important events that influence fitness while others are unimportant. Individuals can learn specific sound cues and ‘soundscapes’ and use them for vital activities such as foraging, predator avoidance, communication and orientation. Most research with sounds in elasmobranchs has focused on hearing thresholds and attractiveness to sound sources, but very little is known about their abilities to learn about sounds, especially in benthic species. Here we investigated if juvenile Port Jackson sharks could learn to associate a musical stimulus with a food reward, discriminate between two distinct musical stimuli, and whether individual personality traits were linked to cognitive performance. Five out of eight sharks were successfully conditioned to associate a jazz song with a food reward delivered in a specific corner of the tank. We observed repeatable individual differences in activity and boldness in all eight sharks, but these personality traits were not linked to the learning performance assays we examined. These sharks were later trained in a discrimination task, where they had to distinguish between the same jazz and a novel classical music song, and swim to opposite corners of the tank according to the stimulus played. The sharks’ performance to the jazz stimulus declined to chance levels in the discrimination task. Interestingly, some sharks developed a strong side bias to the right, which in some cases was not the correct side for the jazz stimulus.     

The latency complex: the dead hand of anti‐development

It is common knowledge that the same phenomena can be viewed in a variety of ways. This paper considers the implications of a constellation observed in some adult patients who have increasingly reminded the author of some of the children of latency age with whom he has also worked. In the literature these patients may also have been thought about in terms of ‘defences of the self’ (Fordham), patients who are ‘difficult to reach’ (Joseph), ‘psychic retreats’ (Steiner), and those who make ‘attacks on linking’ (Bion). They may equally be considered in terms of schizoid, narcissistic or borderline personalities, or as showing features on the autistic spectrum, such as mindlessness and extreme obsessionality. Writers such as Helene Deutsch with her concept of an ‘as‐if personality’, Winnicott with his ‘false self’, and Rosenfeld, discussing the split‐off parts of the personality in narcissistic patients, have also offered much to think about in their consideration of some of these phenomena. This paper proposes yet another vertex – the author's own imaginative conjecture – that is by no means mutually exclusive of any of these others.     

The temperamental nature of personality

Historically, the terms ‘temperament’, ‘character’, and ‘personality’ have been used to refer to what we now mean by the term ‘personality’. Temperament refers to the raw material out of which personality evolves. Personality is a person's coherent manner of interacting with himself/herself and with the environment. The concept of temperament has been prominent with Eastern European psychologists and with developmental psychologists in North America. A number of developmental theories of temperament are discussed, and differences and similarities between temperament parameters and personality parameters are described. The genetics of personality are presented and evaluated. Mechanistic and dynamic interactions are distinguished, and the multidimensional interaction model of anxiety and relevant research are discussed. A preliminary interaction model of anxiety, stress, and coping is presented. Finally, the temperamental nature of personality is discussed, and suggestions for possible rapprochements between personality and temperament are presented.
