Massed extinction trials produce better short-term but worse long-term loss of context conditioned fear responses than spaced trials

A series of experiments studied the effects of the interval between extinction trials on the loss of context conditioned freezing responses. Rats were shocked in one context (A) but not in another (B) and subjected to extinction trials in context A. In Experiment 1, massed trials produced more rapid loss than spaced trials. A shift from spaced to massed trials maintained this loss, but the shift from massed to spaced trials restored lost responses. Experiments 2-5 examined this effect of massed trials on responding across spaced trials. They provided evidence that (a) a single trial was as effective as multiple daily massed trials, (b) learning occurred on the first of the massed trials but not on later ones, and (c) the first trial reduced the amount learned across subsequent massed trials. Finally, alternating extinction trials in A and B produced more response loss across spaced trials than blocks of trials in A and B. The results were discussed in terms of the role accorded to self-generated priming in the models developed by A. R. Wagner (1978, 1981).     

Warding off the evil eye: when the fear of being envied increases prosocial behavior

The fear of being envied makes people act prosocially, in an attempt to ward off the potentially destructive effects of envy. In three experiments, people who were in a superior position and could be envied were more likely than control participants to give time-consuming advice to a potentially envious person or to help a potentially envious person pick up erasers she had accidentally scattered. However, helping behavior increased only if envy was likely to be malicious rather than benign. People who were better off did not increase their helping behavior toward people in general, but increased their helping only toward the potentially envious. This finding is consistent with the idea that the better off act more prosocially as an appeasement strategy. The fear of being envied serves useful group functions, because it triggers prosocial behavior that is likely to dampen the potentially destructive effects of envy and simultaneously helps to improve the situation of people who are worse off.     

Dishabituation processes in height fear and dental fear: an indirect test of the non-associative model of fear acquisition

The fear dishabituation hypothesis described in the non-associative model of fear acquisition was tested in a longitudinal birth cohort study. Results were consistent with height fear and phobia dishabituation. That is, 're-emergence' of a fear of heights occurred between age 11 and 18 years among individuals who reported higher levels of non-specific stress at age 15. Interestingly, there was no evidence for dental fear dishabituation--a finding consistent with the non-associative model of fear acquisition. Strengths and weaknesses of the study were considered and the results discussed in relation to laboratory-based findings on (dis)habituation.     

Focalism and the underestimation of future emotion: when it's worse than imagined

People typically exaggerate the emotional impact of future events. This occurs because of focalism, the tendency to focus on one event and neglect to consider how emotion will be mitigated by the surrounding context. Neglecting context, however, should lead people to underestimate future emotion when context focuses attention on the event. In Study 1, participants underestimated the intensity of their future negative emotions when they reported reactions to a romantic break-up on Valentine's Day versus 1 week before. This relationship was mediated by how frequently they thought about the break-up. In Study 2, participants underestimated the emotional impact of a lost prize when the experimental context forced them to focus on the prize versus when the prize was less evident. Thus, failing to account for the extent to which context would focus attention on the event, a form of focalism, led to underestimation of emotional reactions to a negative event.     

Anxiety sensitivity, body vigilance and fear of pain

The aim of the present study was to investigate the role of anxiety sensitivity (AS) as a factor relevant to pain and pain persistence. Two studies were conducted to examine the relationship between AS, body vigilance and the experience of pain in non-clinical samples. Study 1 investigated the relationship between AS and body vigilance that was operationalized by the detection latency for innocuous electrical stimuli; trait anxiety and neuroticism were also included as covariates. Results indicated that the high AS group (N=69) presented shorter detection latency than the low AS group (N=70); neuroticism and trait anxiety did not have significant effects on detection latency. Using another sample, Study 2 investigated the relationship between AS, body vigilance, pain tolerance, catastrophizing, and self-reported distress and pain during a cold pressor task. Neuroticism, trait anxiety and fear of pain were included as covariates. Results showed significant differences between high- (N=66) and low- (N=69) AS groups in body vigilance, catastrophizing and tolerance. The covariates neuroticism, trait anxiety and fear of pain did not have any significant effects. No significant differences were found in pain and distress ratings. Results from both studies support the importance of AS in body vigilance and the experience of pain. The theoretical, preventive and clinical implications of these findings are discussed.     

A preliminary typology of organisational response to allegations of workplace bullying: see no evil, hear no evil, speak no evil

Organisational representative response is an important factor to consider when counselling employees who have experienced bullying and are considering approaching their organisation for assistance. The author argues that not all responses are supportive and that some responses can further harm an employee. The author presents a review of representative responses, developed from bullying cases the author saw as a counsellor or trainer. The author reviews three organisational representative responses to allegations of bulling: (1) the behaviour is acceptable; (2) the behaviour is inappropriately equally attributed to both parties as a personality conflict; and (3) the behaviour is harmful and inappropriate. The author concludes that counsellors must review potential organisational representative responses with employees and recommends mandatory training for organisational representatives.     

Expectations of sensations,discomfort and fear in dental treatment

A hundred dental patients and 40 dentists were asked to describe the sensations, discomfort and fear which they associated with a number of dental treatments. A number of patients were also asked to describe their experiences immediately after routine conservation procedures. It was concluded that although patients could accurately anticipate the pattern of sensations involved in treatment (even if they had not experienced some of the procedures), they expected more intense sensations and greater discomfort and apprehension than they were likely to experience. Dentists expressed more realistic ideas about the sensations produced by dental treatment. The discrepancy in patients' expectations appears to persist in spite of many discontinuing experiences, the fear of treatment being fostered by discomfort and the intensity of sensations expected, by lack of experience and, to a modest degree, by uncertainty about the sensations anticipated. Cognitive theories of fear do not appear to explain all these influences adequately. These observations support the need for information about sensations in treatment to help not so much with the experience of dentistry but rather with its anticipation.     

Anxiety, pain and type of dental procedure

The anxiety, pain expected and pain experienced of patients arriving for their scheduled dental appointments were measured. The amount of pain expected and experienced was found to be related to the type of dental procedure. Highly anxious patients expected more pain than they experienced when they received drilling/extraction type procedures but the discrepancy was small when they were due to receive a check-up. Low-anxiety patients, by contrast, accurately predicted the amount of pain they would experience, whatever the procedure. The results may explain why anxiety about dentistry is slow to extinguish.     

Manifestations, acquisition and diagnostic categories of dental fear in a self-referred population

This study aimed to clarify how manifestations and acquisition relate to diagnostic categories of dental fear in a population of self-referred dental fear patients, since diagnostic criteria specifically related to dental fear have not been validated. DSM III-R diagnostic criteria for phobias were used to compare with four existing dental fear diagnostic categories, referred to as the Seattle system. Subjects were 208 persons with dental fear who were telephone interviewed, of whom a subsample of 155 responded to a mailed Dental Anxiety Scale (DAS), State-Trait Anxiety Inventory and a modified FSS-II Geer Fear Scale (GFS). Personal interviews and a Dental Beliefs Scale of perceived trust and social interaction with dentists were also used to evaluate a subsample of 80 patients selected by sex and high dental fear. Results showed that the majority of the 80 patients (66%), suffered from social embarrassment about their dental fear problem and their inability to do something about it. The largest cause of their fear (84%) was reported to be traumatic dental experiences, especially in childhood (70%). A minority of patients (16%) could not isolate traumatic experiences and had a history of general fearfulness or anxiety. Analysis of GFS data for the 155 subjects showed that fear of snakes and injuries were highest among women; heights and injections among men. Fear of blood was rarely reported. Spearman correlations between GFS individual items and DAS scores indicated functional independence between dental fear and common fears such as blood, injections and enclosures in most cases. Only in specific types of dental fear did these results support Rachman and Lopatka's contention that fears are thought to summate.(ABSTRACT TRUNCATED AT 250 WORDS)     

Discourse,agency and the question of evil

Abstract

This paper addresses the question of evil from an ethical and discourse-analytical perspective, taking Joan Copjec’s commentary on Kant’s notion of ‘radical evil’ and its relation to human freedom as its point of departure. Specifically, Copjec’s argument, that for Kant (and, one may add, for Lacan) the subject is always “in excess of itself”, provides an important foil for, or corrective to what may seem to be the upshot of Foucault’s notion of discourse (its heuristic value notwithstanding). The latter entails that, insofar as the subject is ineluctably discursively constructed, its actions could be understood as being ‘determined’ by the discursive structure of (its) subjectivity. That is, the subject as agent may seem to lack volitional freedom in the sense that it is merely an instrument of a certain discourse by which it is ’spoken‘. However, Kant’s idea of ’radical evil‘, it is further argued, presupposes that the subject is free, in other words, that it always exceeds itself. In Foucault’ s terms, this would mean that the subject of discourse is able to adopt a counter-discursive position - something Foucault sometimes seems to make room for. What Kant calls ‘radical evil’ may be understood as something that occurs in the world through human agency, in the face of the possibility of an alternative course of action; that is, it is chosen - even if we only know this in retrospect through the phenomenon of guilt. i, in contrast, it is understood as being ‘diabolical’ in the sense of being unavoidably and irresistibly part and parcel of human ‘nature’, no one could condemn it in moral terms. This line of thinking is fleshed out, or given concrete significance by means of a discourse-analysis of documents pertaining to the so-called ‘ripper-rapist’ (criminal) case in Port Elizabeth, South Africa, in the mid-1990s.

Two is better than one, but mine is better than ours: Preschoolers’ executive function during co-play

The current study investigated how playing with another individual may influence 3- and 4-year-olds’ executive function in the Less-Is-More (LIM) task, where children point to the tray with the smaller amount of treats so as to obtain the larger amount of treats in the other tray. In Experiment 1, 35 Singaporean children were tested with a self version and a co-player-split version of the LIM task. Results showed that children appeared to be less impulsive when playing with a co-player than when playing individually. Experiment 2 further investigated how the intention of the co-player, collective profit oriented versus individual profit oriented, may influence children’s executive function. In total, 96 children were tested with a self version, a co-player-share version, and a co-player-opponent version. Results showed that the co-playing facilitation effect appeared in only the co-player-opponent version. Together, the results of the current study showed that when preschoolers play with an individual who shares a common goal with them, they may become more efficient in executive control.     

Temperance: with a consideration of evil,violence, and pedagogy

The article investigates the meaning of temperance by noting some cultural assumptions, raising the question as to why this classical virtue has largely disappeared from modern ethical discourse. By means of some historical notes temperance is identified as the unifying virtue in the person and in society. In its Christian form it is related to love of the transcendent goal of human life. By being similarly goal driven, education should consider the cardinal virtues and celebrate them through worship.     

Desired control,felt control,and dental pain: Recent findings and remaining issues

This paper reviews a series of studies examining how desire for control among dental patients affects their reaction to dental treatment. This research (across eight samples) indicates that low perceived control is associated with heightened stressful responding before and during dental treatment only among patients reporting high desire for control Thus, the impact of low perceived control appears to be moderated by desire for control. An additional finding is that manipulations of control (e.g., providing information, stress inoculation training) primarily impact patients reporting both a high desire for control (during treatment) and low initial perceived control. These data suggest that consideration of patients' desire for control in addition to their perceived control increases our ability to predict their level of dental stress. Additionally, these data provide initial support for the view that the discrepancy between high desire for control and low perceived control play a causal role in patient's perceptions of dental pain and fear.This research was supported by grant USPHS-NIH 5 RO1 DEO 9419-02 (H.

Better (or worse) for some than others: Individual differences in the positivity offset and negativity bias

People tend to respond with more positive than negative affect to mildly emotional stimuli (i.e., positivity offset) and respond more strongly to very negative than to matched positive stimuli (i.e., negativity bias). In the current study, the authors examine individual differences in the positivity offset and negativity bias and demonstrate that both are stable over time and generalize across different kinds of stimuli (e.g., pictures, sounds, words, games of chance). Furthermore, the positivity offset and negativity bias are not redundant with traditional personality measures and exhibit differential predictive validity, such that both types of measures predict behavior in meaningful ways. Implications for a comprehensive understanding of affect and emotion and their relationship to physical and mental health are discussed.     

Societal QOL is More than the Sum of QOL of Individuals: The Whole is Greater than the Sum of the Parts

I submit that we are too focused on individual-level happiness research at the expense of societal level QOL research. That is, societal QOL cannot be simply treated as the sum of the happiness of individual citizens. In making this assertion I review and discuss Abott Ferris’ latest book: Approaches to Improving the Quality of Life (published by Springer, 2010).
