According to the perceptual symbols theory (Barsalou, 1999), sensorimotor simulations underlie the representation of concepts. Simulations are componential in the sense that they vary with the context in which the concept is presented. In the present study, we investigated whether representations are affected by recent experiences with a concept. Concept names (e.g., APPLE) were presented twice in a property verification task with a different property on each occasion. The two properties were either from the same perceptual modality (e.g.,green, shiny) or from different modalities (e.g.,tart, shiny). All stimuli were words. There was a lag of several intervening trials between the first and second presentation. Verification times and error rates for the second presentation of the concept were higher if the properties were from different modalities than if they were from the same modality.

A variant allele in the promoter region of the serotonin transporter gene, SLC6A4, the s allele, is associated with increased vulnerability to develop anxiety-related traits and depression. Furthermore, functional magnetic resonance imaging (fMRI) studies reveal that s carriers have increased amygdala reactivity in response to aversive stimuli, which is thought to be an intermediate phenotype mediating the influences of the s allele on emotionality. We used high-resolution microPET [18F]fluoro-2-deoxy-D-glucose (FDG) scanning to assess regional brain metabolic activity in rhesus monkeys to further explore s allele-related intermediate phenotypes. Rhesus monkeys provide an excellent model to understand mechanisms underlying human anxiety, and FDG microPET allows for the assessment of brain activity associated with naturalistic environments outside the scanner. During FDG uptake, monkeys were exposed to different ethologically relevant stressful situations (relocation and threat) as well as to the less stressful familiar environment of their home cage. The s carriers displayed increased orbitofrontal cortex activity in response to both relocation and threat. However, during relocation they displayed increased amygdala reactivity and in response to threat they displayed increased reactivity of the bed nucleus of the stria terminalis. No increase in the activity of any of these regions occurred when the animals were administered FDG in their home cages. These findings demonstrate context-dependent intermediate phenotypes in s carriers that provide a framework for understanding the mechanisms underlying the vulnerabilities of s-allele carriers exposed to different types of stressors.

<p>Counselling psychology is increasingly curious regarding the benefits of mindfulness and meditation. This research explores the relationship between the clinical work of psychotherapists and their long-term Buddhist-informed meditation. This is an emerging and cross-cultural field. Thorne's (2008) interpretive description guided this exploratory qualitative study of the experiences of four registered psychologists. This study finds that meditation supports an unconditional, compassionate therapeutic stance that serves therapy through the development of the therapeutic relationship. Further, Buddhist-informed meditation appears to promote integrative functioning in the therapists and is related to integrated clinical decision-making. This study dips into areas of transpersonal and Buddhist psychology that require further culturally-sensitive investigation. Future directions for research are presented.</p>

Social class is shaped by an individual's material resources as well as perceptions of rank vis-à-vis others in society, and in this article, we examine how class influences behavior. Diminished resources and lower rank create contexts that constrain social outcomes for lower-class individuals and enhance contextualist tendencies--that is, a focus on external, uncontrollable social forces and other individuals who influence one's life outcomes. In contrast, abundant resources and elevated rank create contexts that enhance the personal freedoms of upper-class individuals and give rise to solipsistic social cognitive tendencies--that is, an individualistic focus on one's own internal states, goals, motivations, and emotions. Guided by this framework, we detail 9 hypotheses and relevant empirical evidence concerning how class-based contextualist and solipsistic tendencies shape the self, perceptions of the social environment, and relationships to other individuals. Novel predictions and implications for research in other socio-political contexts are considered.

Power increases the tendency to behave in a goal-congruent fashion. Guided by this theoretical notion, we hypothesized that elevated power would strengthen the positive association between prosocial orientation and empathic accuracy. In 3 studies with university and adult samples, prosocial orientation was more strongly associated with empathic accuracy when distinct forms of power were high than when power was low. In Study 1, a physiological indicator of prosocial orientation, respiratory sinus arrhythmia, exhibited a stronger positive association with empathic accuracy in a face-to-face interaction among dispositionally high-power individuals. In Study 2, experimentally induced prosocial orientation increased the ability to accurately judge the emotions of a stranger but only for individuals induced to feel powerful. In Study 3, a trait measure of prosocial orientation was more strongly related to scores on a standard test of empathic accuracy among employees who occupied high-power positions within an organization. Study 3 further showed a mediated relationship between prosocial orientation and career satisfaction through empathic accuracy among employees in high-power positions but not among employees in lower power positions. Discussion concentrates upon the implications of these findings for studies of prosociality, power, and social behavior.

How is spirituality, which refers to the emotional connection to the transcendent, related to compassion and to altruistic behavior towards strangers? Are the effects of spirituality different from those of religiosity, which refers to living according to the rules and rituals of religion? We hypothesized that, even though correlated, spirituality and religiosity would have different associations with compassion and altruistic behavior. The first two studies documented that more spiritual individuals experience greater compassion, and that this effect was specific to spirituality and could not be explained by religiosity. Because compassion has the capacity to motivate people to transcend selfish motives and act in altruistic fashion towards strangers, we reasoned that spirituality (but not religiosity) would predict altruistic behavior and that this link would be explained, in part, by compassion. Indeed, Studies 3, 4, and 5 found that more spiritual individuals behaved more altruistically in economic choice and decision-making tasks, and that the tendency of spiritual individuals to feel greater compassion mediated the relationship between spirituality and altruistic behavior. In contrast, more religious participants did not consistently feel more compassion nor behave more altruistically. Together, these findings help clarify why spirituality produces more prosocial behavior.

<p>Previous research has reported that individuals high in the need for Power, high in inhibition, and high in power stress (the HHH group) are more likely than other individuals to report more severe illnesses. The present study investigates the possibility that the mechanism underlying this relationship is greater sympathetic activation in the HHH group which has an immunosuppressive effect. College males with the HHH syndrome reported more frequent and more severe illnesses than other individuals, as in previous studies. More of the HHH than other subjects also showed above average epinephrine excretion rates in urine and below average concentrations of immunoglobulin A in saliva (S-IgA). Furthermore, higher rates of epinephrine excretion were significantly associated with lower S-IgA concentrations, and lower S-IgA concentrations were significantly associated with reports of more frequent illnesses. The findings are interpreted as consistent with the hypothesis that a strong need for Power, if it is inhibited and stressed, leads to chronic sympathetic overactivity which has an immunosuppressive effect making individuals characterized by this syndrome more susceptible to illness.</p>

Laughter facilitates the adaptive response to stress by increasing the psychological distance from distress and by enhancing social relations. To test these hypotheses, the authors related measures of bereaved adults' laughter and smiling 6 months postloss to measures of their (a) subjective emotion and dissociation from distress, (b) social relations, and (c) responses they evoked in others. Duchenne laughter, which involves orbicularis oculi muscle action, related to self-reports of reduced anger and increased enjoyment, the dissociation of distress, better social relations, and positive responses from strangers, whereas non-Duchenne laughter did not. Lending credence to speculations in the ethological literature, Duchenne laughter correlated with different intrapersonal and interpersonal responses than Duchenne smiles. Discussion focuses on the relevance of these findings to theories of positive emotion.

BACKGROUND: Hypothalamic-pituitary-adrenal (HPA) system activation is adaptive in response to stress, and HPA dysregulation occurs in stress-related psychopathology. It is important to understand the mechanisms that modulate HPA output, yet few studies have addressed the neural circuitry associated with HPA regulation in primates and humans. Using high-resolution F-18-fluorodeoxyglucose positron emission tomography (FDG-PET) in rhesus monkeys, we assessed the relation between individual differences in brain activity and HPA function across multiple contexts that varied in stressfulness. METHODS: Using a logical AND conjunctions analysis, we assessed cortisol and brain metabolic activity with FDG-PET in 35 adolescent rhesus monkeys exposed to two threat and two home-cage conditions. To test the robustness of our findings, we used similar methods in an archival data set. In this data set, brain metabolic activity and cortisol were assessed in 17 adolescent male rhesus monkeys that were exposed to three stress-related contexts. RESULTS: Results from the two studies revealed that subgenual prefrontal cortex (PFC) metabolism (Brodmann's area 25/24) consistently predicted individual differences in plasma cortisol concentrations regardless of the context in which brain activity and cortisol were assessed. CONCLUSIONS: These findings suggest that activation in subgenual PFC may be related to HPA output across a variety of contexts (including familiar settings and novel or threatening situations). Individuals prone to elevated subgenual PFC activity across multiple contexts may be individuals who consistently show heightened cortisol and may be at risk for stress-related HPA dysregulation.

What happens when people suppress their emotions when they sacrifice for a romantic partner? This multimethod study investigates how suppressing emotions during sacrifice shapes affective and relationship outcomes. In Part 1, dating couples came into the laboratory to discuss important romantic relationship sacrifices. Suppressing emotions was associated with emotional costs for the partner discussing his or her sacrifice. In Part 2, couples participated in a 14-day daily experience study. Within-person increases in emotional suppression during daily sacrifice were associated with decreases in emotional well-being and relationship quality as reported by both members of romantic dyads. In Part 3, suppression predicted decreases in relationship satisfaction and increases in thoughts about breaking up with a romantic partner 3 months later. In the first two parts of the study, authenticity mediated the costly effects of suppression. Implications for research on close relationships and emotion regulation are discussed.

<p>Few counseling programs directly address the importance of self-care in reducing stress and burnout in their curricula. A course entitled Mind/Body Medicine and the Art of Self-Care was created to address personal and professional growth opportunities through self-care and mindfulness practices (meditation, yoga, qigong, and conscious relaxation exercises). Three methods of evaluating this 15-week 3-credit mindfulness-based stress reduction (MBSR) course for counseling students indicated positive changes for students in learning how to manage stress and improve counseling practice. Students reported positive physical, emotional, mental, spiritual, and interpersonal changes and substantial effects on their counseling skills and therapeutic relationships. Information from a focus group, qualitative reports, and quantitative course evaluations were triangulated; all data signified positive student responses to the course, method of teaching, and course instructor. Most students reported intentions of integrating mindfulness practices into their future profession.</p>

<p>Preparation for the role of therapist can occur on both professional and personal levels. Research has found that therapists are at risk for occupationally related psychological problems. It follows that self-care may be a useful complement to the professional training of future therapists. The present study examined the effects of one approach to self-care, Mindfulness-Based Stress Reduction (MBSR), for therapists in training. Using a prospective, cohort-controlled design, the study found participants in the MBSR program reported significant declines in stress, negative affect, rumination, state and trait anxiety, and significant increases in positive affect and self-compassion. Further, MBSR participation was associated with increases in mindfulness, and this enhancement was related to several of the beneficial effects of MBSR participation. Discussion highlights the potential for future research addressing the mental health needs of therapists and therapist trainees.</p>

Although tantrums are among the most common behavioral problems of young children and may predict future antisocial behavior, little is known about them. To develop a model of this important phenomenon of early childhood, behaviors reported in parental narratives of the tantrums of 335 children aged 18 to 60 months were encoded as present or absent in consecutive 30-second periods. Principal Component (PC) analysis identified Anger and Distress as major, independent emotional and behavioral tantrum constituents. Anger-related behaviors formed PCs at three levels of intensity. High-intensity anger decreased with age, and low-intensity anger increased. Distress, the fourth PC, consisted of whining, crying, and comfort-seeking. Coping Style, the fifth PC, had high but opposite loadings on dropping down and running away, possibly reflecting the tendency to either "submit" or "escape." Model validity was indicated by significant correlations of the PCs with tantrum variables that were, by design, not included in the PC analysis.

This article completes the analysis of parental narratives of tantrums had by 335 children aged 18 to 60 months. Modal tantrum durations were 0.5 to 1 minute; 75% of the tantrums lasted 5 minutes or less. If the child stamped or dropped to the floor in the first 30 seconds, the tantrum was likely to be shorter and the likelihood of parental intervention less. A novel analysis of behavior probabilities that permitted grouping of tantrums of different durations converged with our previous statistically independent results to yield a model of tantrums as the expression of two independent but partially overlapping emotional and behavioral processes: Anger and Distress. Anger rises quickly, has its peak at or near the beginning of the tantrum, and declines thereafter. Crying and comfort-seeking, components of Distress, slowly increase in probability across the tantrum. This model indicates that tantrums can provide a window on the intense emotional processes of childhood.

We investigated the top-down influence of working memory (WM) maintenance on feedforward perceptual processing within occipito-temporal face processing structures. During event-related potential (ERP) recordings, subjects performed a delayed-recognition task requiring WM maintenance of faces or houses. The face-sensitive N170 component elicited by delay-spanning task-irrelevant grayscale noise probes was examined. If early feedforward perceptual activity is biased by maintenance requirements, the N170 ERP component elicited by probes should have a greater N170 amplitude response during face relative to house WM trials. Consistent with this prediction, N170 elicited by probes presented at the beginning, middle, and end of the delay interval was greater in amplitude during face relative to house WM. Thus, these results suggest that WM maintenance demands may modulate early feedforward perceptual processing for the entirety of the delay duration. We argue based on these results that temporally early biasing of domain-specific perceptual processing may be a critical mechanism by which WM maintenance is achieved.

Rats were implanted bilaterally with cannulae into the dorsal hippocampus and trained in a Pavlovian fear-conditioning paradigm. Four groups of rats were infused intra-cranially with 1-(5'-isoquinolinesulfonyl)-2-methylpiperazine (H7-dihydrochloride), a potent inhibitor of both protein kinase C (PKC) and cAMP-dependent protein kinase (PKA), at different time intervals in order to examine their involvement in the acquisition and consolidation of contextual fear memory. We demonstrate a significant consolidation deficit of long-term contextual fear-conditioning memory that is maximal when PKA and PKC are inhibited at 90 min post-training. These results suggest the existence of a critical time window, during which these enzymes must be activated for the consolidation of long-term memories.

<p>Reviews progress toward the development of a cognitive theory of aptitude for learning and presents descriptive and prescriptive goals for aptitude theories. Preliminary hypotheses about the nature of cognitive processes in aptitude for learning from instruction are reviewed. 12 constituent points of the descriptive theory are presented. Some of these points are summary conclusions on much prior research, whereas others are less well supported at present. However, all contribute to the effort to describe learning and aptitude for learning in conformable terms. Some prescriptive implications of the theory, intended as hypotheses for instructional development and design research in particular locations, are also discussed. (102 ref)</p>

Several randomised controlled trials suggest that mindfulness-based approaches are helpful in preventing depressive relapse and recurrence, and the UK Government’s National Institute for Health and Clinical Excellence has recommended these interventions for use in the National Health Service. There are good grounds to suggest that mindfulness-based approaches are also helpful with anxiety disorders and a range of chronic physical health problems, and there is much clinical and research interest in applying mindfulness approaches to other populations and problems such as people with personality disorders, substance abuse, and eating disorders. We review the UK context for developments in mindfulness-based approaches and set out criteria for mindfulness teacher competence and training steps, as well as some of the challenges and future directions that can be anticipated in ensuring that evidence-based mindfulness approaches are available in health care and other settings.

This study explores two conflictingmodels of how patients experience mind-bodytherapies; these models frame the design of aclinical trial examining the effects of qigong (a traditional Chinese movementtherapy) on the immune systems of former cancerpatients. Data consist of ethnographic researchand in-depth interviews conducted at the Bostonteaching hospital where the trial is to takeplace. These interviews, with biomedicalresearchers who designed the trial and with theqigong master responsible for the qigong arm of the trial, reveal twofundamentally different understandings of howqigong is experienced and how thatexperience may be beneficial. The biomedicalteam sees qigong as a non-specifictherapy which combines relaxation and exercise. The qigong master, on the other hand,sees qigong as using specific movementsand visualizations to direct mental attentionto specific areas of the body. Thus while thebiomedical team frames qigong as a“mind-body” practice, the qigong masterframes it as a “mind-in-body” practice. This research suggests that the biomedicalnotion that mind-body therapies work byeliciting mental relaxation is only one way ofthinking about how patients experiencemodalities like qigong: indeed,characterizations of mind-body therapies whichemphasize a mental sense of relaxation may bespecific to biomedicine and the cultures whichsurround it. More broadly, the paper arguesthat gaps in understanding between researchersand practitioners may be hindering scientificefforts to assess therapies like qigong.It concludes by proposing that clinical trialsof traditional and alternative therapies buildethnographic inquiry about practitionerexperience into the design process.

This preliminary study examined whether the practice of mind–body techniques decreases symptoms of posttraumatic stress in adolescents. Posttraumatic Stress Reaction Index questionnaires were collected from 139 high school students in Kosovo who participated in a 6-week program that included meditation, biofeedback, drawings, autogenic training, guided imagery, genograms, movement, and breathing techniques. Three separate programs were held approximately 2 months apart. There was no control group. Posttraumatic stress scores significantly decreased after participation in the programs. These scores remained decreased in the 2 groups that participated in the follow-up study when compared to pretest measures. These data indicate that mind–body skills groups were effective in reducing posttraumatic stress symptoms in war-traumatized high school students.
