Informant reports add incrementally to the understanding of the perfectionism–depression connection: Evidence from a prospective longitudinal study

Perfectionism is a putative risk factor for depressive symptoms. However, most research in this area uses cross-sectional designs (which fail to address temporal precedence) and mono-source designs (which are influenced by various biases). The present study overcomes these limitations by using a novel design involving both self- and informant reports of self-critical perfectionism (i.e., negative reactions to perceived failures, concern over others’ criticism and expectations, doubts about performance abilities, and intense self-rebuke). It was hypothesized that self- and informant reports of self-critical perfectionism would correlate moderately and that self- and informant reports of self-critical perfectionism would predict increases in depressive symptoms over time. A sample of 155 target participants and 588 informants was recruited and studied using a prospective longitudinal design. All study hypotheses were supported, including evidence that self- and informant reports of self-critical perfectionism each add incrementally to the understanding of the self-critical perfectionism–depressive symptoms connection. Informant reports may provide a more complete picture of the self-critical perfectionist and her or his vulnerability to depressive symptoms.     

Quasi-Realism,Sensibility Theory,and Ethical Relativism

Because of a widespread criticism of the Enlightenment sense of reason for its unilateral privileging of unity and its solipsistic conception of the thinking subject, many turn to postmodern difference as a remedy. But an alternative can also be found in a renewed appropriation of the tradition. This essay is an attempt at such an appropriation, through a philosophical analysis of Heraclitus' conception of logos. A new interpretation of Heraclitus is offered, which affirms the equiprimordiality of unity and difference. This view is shown to have implications first of all for the mode of reasoning: thought, in its most genuine sense, cannot be accomplished in isolation but is an essentially joint act. Further, the view has implications for the content or object of thought: the ‘seat’ of intelligibility is not the abstract idea which the mind assimilates to itself but rather the concrete whole, the complex ‘one-many’ structure in the world, in which minds constitutively participate. An attempt is made, at the end of the essay, to show how the convergence of form and content, and the concrete sense of rationality it implies, comes to dramatic expression in Heraclitus' style.     

Binocular vision enhances a rapidly evolving affordance priming effect: Behavioural and TMS evidence

Extensive research has suggested that simply viewing an object can automatically prime compatible actions for object manipulation, known as affordances. Here we explored the generation of covert motor plans afforded by real objects with precision (‘pinchable’) or whole-hand/power (‘graspable’) grip significance under different types of vision. In Experiment 1, participants viewed real object primes either monocularly or binocularly and responded to orthogonal auditory stimuli by making precision or power grips. Pinchable primes facilitated congruent precision grip responses relative to incongruent power grips, and vice versa for graspable primes, but only in the binocular vision condition. To examine the temporal evolution of the binocular affordance effect, participants in Experiment 2 always viewed the objects binocularly but made no responses, instead receiving a transcranial magnetic stimulation pulse over their primary motor cortex at three different times (150, 300, 450 ms) after prime onset. Motor evoked potentials (MEPs) recorded from a pinching muscle were selectively increased when subjects were primed with a pinchable object, whereas MEPs from a muscle associated with power grips were increased when viewing graspable stimuli. This interaction was obtained both 300 and 450 ms (but not 150 ms) after the visual onset of the prime, characterising for the first time the rapid development of binocular grip-specific affordances predicted by functional accounts of the affordance effect.     

Knowledge, Attitudes, and Beliefs of Arab-American Women Regarding Inherited Cancer Risk

The increasing incidence of breast cancer in the Arab world, coupled with a relatively early age of onset, raises concern for the presence of hereditary risk factors in this population. However, due to potential structural and cultural barriers, Arab Americans make up the smallest percentage of individuals tested for Hereditary Breast and Ovarian Cancer Syndrome in the United States. The objectives of this qualitative pilot focus group of 13 Arab-American women were to explore attitudes, knowledge and beliefs regarding hereditary breast cancer in the Arab-American community in metropolitan Detroit, identify barriers that would prevent women from seeking hereditary cancer screening/testing and determine who women would talk to about inherited cancer. Results indicated that cultural beliefs and personal experiences with cancer influenced the women’s perspectives on hereditary cancer risk. A high level of secrecy about cancer within Arab-American families was present, which may prevent accurate risk assessment and referral for genetic services. Other identified barriers that may influence hereditary risk assessment included stigma, fears and misconceptions of cancer. While these barriers were present, participants also expressed a strong need for education and tailored cancer risk information for their community.     

Relative Efficacy of Cognitive-Behavioral Therapy Administered by Videoconference for Posttraumatic Stress Disorder: A Six-Month Follow-Up

Until recently, only one study was published on cognitive-behavioral therapy (CBT) of posttraumatic stress disorder (PTSD) in individual therapy via videoconference (Germain, Marchand, Bouchard, Drouin, & Guay, 2009 Germain, V., Marchand, A., Bouchard, S., Drouin, M. S. and Guay, S. 2009. Effectiveness of cognitive behavioural therapy administered by videoconference for posttraumatic stress disorder. Cognitive Behaviour Therapy, 38: 42–53. [Taylor & Francis Online] , [Google Scholar]); however, it only assessed the posttreatment effect. This study presents the follow-up of Germain et al.'s (2009 Germain, V., Marchand, A., Bouchard, S., Drouin, M. S. and Guay, S. 2009. Effectiveness of cognitive behavioural therapy administered by videoconference for posttraumatic stress disorder. Cognitive Behaviour Therapy, 38: 42–53. [Taylor & Francis Online] , [Google Scholar]) study. The main goal was to compare the effectiveness after six months of CBT for PTSD either face-to-face (n = 24) or by videoconference (n = 12). Each participant received CBT for 16 to 25 weeks and completed various questionnaires before and after treatment and at a six-month follow-up. The two treatments had equivalent levels of symptom reduction (Modified PTSD Symptom Scale: η² < 0.01, p > .05) and proportion of patients with a clinically significant change in symptoms (42% for face-to-face vs. 38% for videoconferencing, p > .05). Thus, CBT for PTSD via videoconference seems to be a viable alternative when adequate face-to-face treatments are less available.     

Workers,groups and gangs: consultation to residential adolescent teams

This paper discusses how the internal worlds of adolescents who are looked after in residential care homes impact upon workers and generate complex dynamics within teams. This is especially so regarding internal parental objects and couplings, which inevitably include those of abandoning, abusive and ambivalent parental figures. Versions of these are projected and enacted between adolescents and workers, workers and managers, team and consultant. Conceptual thinking about groups and gangs is drawn upon to help illuminate the emotional phenomena encountered in team consultation meetings as described in the paper. Clinical material is given of working in the transference as consultant to the team, in order to illustrate processes of containment and the opportunity for thinking to take place. In this, there is movement between different states of mind within the team. The paper seeks to demonstrate a way of consulting to residential teams working with looked after adolescents and to show how this can mediate some of the enactments by workers and teams of projected states and transferential phenomena. Associated with this, there can be a deepening of the team's understanding of the emotional experience of the adolescents in their care.     

Making heads or tails of probability: An experiment with random generators

Background. The equiprobability bias is a tendency for individuals to think of probabilistic events as ‘equiprobable’ by nature, and to judge outcomes that occur with different probabilities as equally likely. The equiprobability bias has been repeatedly found to be related to formal education in statistics, and it is claimed to be based on a misunderstanding of the concept of randomness. Aims. The aim of the present study was to examine whether experimenting with random generators would decrease the equiprobability bias. Sample. The participants were 108 psychology students whose performance was measured either immediately after taking part in a training session (n= 55), or without doing any training exercises (n= 53). Method. The training session consisted of four activities. These included generating random sequences of events, and learning about the law of large numbers. Subsequently, the participants were tested on a series of equiprobability problems, and a number of other problems with similar structure and content. Results. The results indicated that the training successfully decreased the equiprobability bias. However, this effect was moderated by participants’ cognitive ability (i.e., higher ability participants benefitted from the training more than participants with lower cognitive ability). Finally, the training session had the unexpected side effect of increasing students’ susceptibility to the representativeness heuristic. Conclusions. Experimenting with random generators has a positive effect on students’ general understanding of probability, but the same time it might increase their susceptibility to certain biases (especially, to the representativeness heuristic). These findings have important implications for using training methods to improve probabilistic reasoning performance.     

Feeling left out? The mediating role of perceived rejection on workgroup mistreatment and affective,behavioral, and organizational outcomes and the moderating role of organizational norms

This two‐study paper examines the detrimental impact of workgroup mistreatment and the mediating role of perceived rejection. In Study 1, perceived rejection emerged as a mediator between workgroup mistreatment and depression, organization‐based self‐esteem, organizational deviance, and organizational citizenship behaviors. In Study 2, the role of organizational norms was examined. Employees who experienced supportive organizational norms reported lower levels of perceived rejection, depression and turnover intentions, and higher levels of organization‐based self‐esteem and job satisfaction. Employees in the supportive norms condition reported that they were more likely to seek reconciliation after experiencing mistreatment than those who experienced low support. Perceived rejection also emerged as a mediator. Results, practical implications, and future research directions are discussed.     

Chronometric Analysis of the Posturo-Kinetic Programming of Voluntary Movement

Posturo-kinetic programming was investigated in a simple reaction time paradigm. Standing subjects performed voluntary upper limb elevations under three conditions differing by the importance of their destabilizing effect on the initial balance. Three indexes were considered: the reaction time (RT) corresponding to delay between the response signal (RS) and the onset of the upper limb acceleration at wrist level (Aw); the motor latency (ML) corresponding to delay between RS and onset of the earlier of the two accelerations at shank level (As) which was previously shown to indicate the onset of postural adjustments; and the postural anticipation (PA) corresponding to the delay between the onset of the earliest As and the onset of Aw. The results showed that the RT varied in relation to parameters of the forthcoming movement. RT variations were essentially due to differences in the PA. It appeared that the ML depended on cognitive factors while the PA depended on biomechanical ones. It is concluded that ML corresponds to the “true” reaction time while PA covers the earliest part of the motor response.     

Snoddy (1926) Revisited: Time Scales of Motor Learning

A new 3-stage model based on neuroimaging evidence is proposed by Chein and Schneider (2012). Each stage is associated with different brain regions, and draws on cognitive abilities: the first stage on creativity, the second on selective attention, and the third on automatic processing. The purpose of the present study was to scrutinize the validity of this model for 1 popular learning paradigm, visuomotor adaptation. Participants completed tests for creativity, selective attention and automated processing before attending in a pointing task with adaptation to a 60° rotation of visual feedback. To examine the relationship between cognitive abilities and motor learning at different times of practice, associations between cognitive and adaptation scores were calculated repeatedly throughout adaptation. The authors found no benefit of high creativity for adaptive performance. High levels of selective attention were positively associated with early adaptation, but hardly with late adaptation and de-adaptation. High levels of automated execution were beneficial for late adaptation, but hardly for early and de-adaptation. From this we conclude that Chein and Schneider's first learning stage is difficult to confirm by research on visuomotor adaptation, and that the other 2 learning stages rather relate to workaround strategies than to actual adaptive recalibration.
