Social mimetic behaviour and social anticipation in dogs: preliminary results.

Learning contributes to the development of mutual mimicry in group mates. The aim of our study was to investigate whether dogs would initiate walking a detour if they were repeatedly exposed to the detouring behaviour of their owner. Eight dog owners were asked to modify their usual way of approaching their home at the end of their daily walks, namely, to make a short detour before the entrance. Owners performed the detour at least 180 times, over a period of 3-6 months. During the first 30 detours (trials 1-30) all dogs followed the owner on the new route. Between trials 151 and 180, four dogs started to walk the detour before the owner displayed any intention to walk in that direction in 50-93% of the cases. Further observations that were carried out on one dog showed that the initialisation of the detours manifested sooner if a second familiar person started to walk the detours. Interestingly, the dog persisted in initialising detours long after the owners stopped detouring. We describe the observed phenomenon in the framework of social anticipation that manifests when an animal learns the proper sequence of an act performed by another animal, so that it can (1) predict the action in this sequence, and (2) as a result start either a similar or a complementary action as a response. These observations suggest that the dogs' social anticipation ability contributes to behavioural synchronisation and cooperative processes between dog and owner.

The treatment of social phobia: the differential effectiveness of exposure in vivo and an integration of exposure in vivo, rational emotive therapy and social skills training.

Thirty-four social phobic patients were treated with either exposure in vivo or an integrated treatment, consisting of rational emotive therapy, social skills training and exposure in vivo. Comparison with a waiting-list control group showed the effectiveness of both treatments. Contrary to expectations, the integrated approach was not superior over exposure in vivo alone. Also, the long-term effectiveness of both treatments was equally good.

Testosterone removal in rats results in a decrease in social aggression and a loss of social dominance.

Alpha male rats from mixed sex colony groups were tested for aggressiveness toward nonaggressive male intruders. Afterward, they were castrated and implanted with testosterone filled Silastic tubes, castrated and implanted with empty tubes, or sham castrated and implanted with empty tubes. There were significant declines in the aggressiveness (lateral attacks, bites, and piloerection but not on-top) of castrated rats without testosterone replacement but not in castrated rats with testosterone replacement. At a second operation, castrated animals had their testosterone capsules removed or had their empty capsules replaced with testosterone filled capsules. When tested for aggression toward nonaggressive intruders, those alpha males which had testosterone removed declined in aggressiveness while those which had it implanted returned to a level of aggressiveness close to that emitted by sham castrated control animals. Subordinate males became dominant when alpha males were castrated and not given testosterone replacement. In a final series of observations, sham castrated males were found to be more aggressive than castrated males when pitted against one another. It is argued that testosterone plays a primary role in intermale social aggression and that the decline in aggressiveness following castration is typically accompanied by a loss of social dominance.

The Social Rhythm Metric (SRM): measuring daily social rhythms over 12 weeks.

A "Social Rhythm Metric" (SRM) of daily rhythmic behavior (developed previously) was given to 20 treated depressives (in remission) and 15 day-working control subjects for a continuous 12-week period. Long-term use of the SRM appeared feasible with no evidence of a deterioration in scores over the 12 weeks. Comparisons were made between intersubject and intrasubject variability, as well as a study of overall trends in SRM during the 12 weeks. Two further measures from the instrument--the Activity Level Index (ALI) and Other Person Involvement--were developed and shown to be useful adjuncts to the SRM. Although no simple differences in absolute SRM score emerged between patients and controls, there were significant differences in intersubject vs. intrasubject variability between the two groups. The patients showed more intrasubject variability and required more weeks of sampling to achieve a stable "trait" measure. Patients' social rhythms also appeared to be more "other person" prompted than those of controls.

Perfectionism and depressive symptoms 3 years later: negative social interactions, avoidant coping, and perceived social support as mediators.

Although research has demonstrated perfectionism to have a negative impact on the treatment of depression, little research has examined the mechanisms or processes through which perfectionism predicts subsequent depressive symptoms in clinical populations over time. Using data from a prospective, 3-year study of a clinical sample (N = 96), hierarchical regression analyses indicated that perfectionism, assessed by the Dysfunctional Attitude Scale (Weissman AN, Beck AT. Development and validation of the Dysfunctional Attitude Scale: a preliminary investigation. Paper presented at the 86th annual convention of the American Psychological Association, Toronto, Ontario, Canada; 1978), is distinguished from major depression and neuroticism for its relations to depressive symptoms and interpersonal maladjustment 3 years later. Drawing from the model of Dunkley et al (J Couns Psychol 2000;47:437-53), path analysis indicated that Dysfunctional Attitude Scale perfectionism was related to depressive symptoms 3 years later through a number of persistent maladaptive tendencies, including negative social interactions, avoidant coping, and negative perceptions of social support.

Neural correlates of social odor recognition and the representation of individual distinctive social odors within entorhinal cortex and ventral subiculum.

Recognition of individual conspecifics is important for social behavior and requires the formation of memories for individually distinctive social signals. Individual recognition is often mediated by olfactory cues in mammals, especially nocturnal rodents such as golden hamsters. In hamsters, this form of recognition requires main olfactory system input to the lateral entorhinal cortex (LEnt). Here, we tested whether neurons in LEnt and the nearby ventral subiculum (VS) would show cellular correlates of this natural form of recognition memory. Two hundred ninety single neurons were recorded from both superficial (SE) and deep layers of LEnt (DE) and VS while male hamsters investigated volatile odorants from female vaginal secretions. Many neurons encoded differences between female's odors with many discriminating between odors from different individual females but not between different odor samples from the same female. Other neurons discriminated between odor samples from one female and generalized across collections from other females. LEnt and VS neurons showed enhanced or suppressed cellular activity during investigation of previously presented odors and in response to novel odors. A majority of SE neurons decreased firing to odor repetition and increased activity to novel odors. In contrast, DE neurons often showed suppressed activity in response to novel odors. Thus, neurons in LEnt and VS of male hamsters encode information that is critical for the identification and recognition of individual females by odor cues. This study reveals cellular mechanisms in LEnt and VS that may mediate a natural form of recognition memory in hamsters. These neuronal responses were similar to those observed in rats and monkeys during performance in standard recognition memory tasks. Consequently, the present data extend our understanding of the cellular basis for recognition memory and suggest that individual recognition requires similar neural mechanisms as those employed in laboratory tests of recognition memory.

Effects of diazepam, citalopram, methadone and naloxone on PCP-induced stereotyped behaviour and social isolation in the rat social interaction test.

Phencyclidine (PCP) can induce a model psychosis in humans that mimics the positive and negative symptoms of schizophrenia. In the social interaction test PCP induces stereotyped behaviour and social isolation in rats, and these behaviours can be inhibited by antipsychotic drugs. In order to further evaluate the predictive validity of this model of schizophrenia the anxiolytic diazepam (0.02-17.5 micromol/kg; 0.005-5.0 mg/kg), the antidepressant citalopram (0.62-19.8 micromol/kg; 0.3-4.0 mg/kg), the opioid agonist methadone (0.36-5.8 micromol/kg; 0.13-2.0 mg/kg) and the opioid antagonist naloxone (0.34-22.0 micromol/kg; 0.13-8.0 mg/kg) were tested as examples of drugs without antipsychotic activity. The experiments demonstrated that these compounds did not specifically inhibit the behavioural effects of PCP. So far only antipsychotic drugs have been able to specifically inhibit the PCP-induced behaviours.

The social context of gastrointestinal cancer pain: a preliminary study examining the relation of patient pain catastrophizing to patient perceptions of social support and caregiver stress and negative responses.

A number of studies have shown that catastrophizing is an important predictor of pain and disability in persons having persistent pain conditions. The newly developed communal model of catastrophizing maintains that catastrophizing is a part of broader, interpersonal style of coping in which coping efforts are directed at interpersonal goals, rather than solely at pain reduction. This study examined the potential interpersonal correlates of pain catastrophizing in a sample of 70 patients having gastrointestinal cancers and their caregivers. Measures of pain catastrophizing, perceptions of social support, pain level, and pain behavior were obtained from patients. Caregivers completed measures that included their judgments about the patient's pain level, caregiver stress, and their tendency to engage in negative responses (critical or avoidant behaviors). Overall, patients who engaged in catastrophizing reported receiving higher levels of instrumental support. Caregivers of patients who catastrophized, rated the patient as having more pain and engaging in more pain behavior. Caregivers of patients who catastrophized, also reported higher levels of caregiver stress and critical behaviors. Taken together, these preliminary findings suggest that pain catastrophizing has interpersonal correlates and support the need for additional research examining the social context of pain catastrophizing.

Social relationships, social support, and patterns of cognitive aging in healthy, high-functioning older adults: MacArthur studies of successful aging.

This study examines the relationship of social ties and support to patterns of cognitive aging in the MacArthur Studies of Successful Aging (see L. F. Berkman et al., 1993), a cohort study of 1,189 initially high-functioning older adults. Baseline and longitudinal data provide information on initial levels as well as changes in cognitive performance over a 7.5-year period. Linear regression analyses revealed that participants receiving more emotional support had better baseline performance, as did those who were unmarried and those reporting greater conflict with network members. Greater baseline emotional support was also a significant predictor of better cognitive function at the 7.5-year follow-up, controlling for baseline cognitive function and known sociodemographic, behavioral, psychological, and health status predictors of cognitive aging. The findings suggest the potential value of further research on the role of the social environment in protecting against cognitive declines at older ages.

Engaging men as social justice allies in ending violence against women: evidence for a social norms approach.

The field of sexual assault prevention is shifting attention to educational interventions that address the role of men in ending violence against women. Recent studies document the often-misperceived norms men hold about other men's endorsement of rape-supportive attitudes and behaviors. The authors provide further evidence supporting the design of population-based social norms interventions to prevent sexual assault. Data from this study suggest that men underestimate the importance that most men and women place on consent and willingness of most men to intervene against sexual violence. In addition, men's personal adherence to only consensual activity and their willingness to act as women's allies are strongly influenced by their perceptions of other men's and women's norms. These findings support the proposition that accurate normative data, which counters the misperception of rape-supportive environments, can be a critical part of comprehensive campus efforts to catalyze and support men's development as women's social justice allies in preventing sexual violence against women.

Interdisciplinary collaboration between primary care, social insurance and social services in the rehabilitation of people with musculoskeletal disorder: effects on self-rated health and physical performance.

Previous research shows there can be good results from co-financing between welfare sectors on the perceived quality of interprofessional collaboration. However, little is known about the impact on patient outcome of such schemes. This study aimed to assess whether co-financed teams with personnel from primary care, social insurance and social services have any effect on patients' health status. A comparative study of patients attending health care centres with and without a co-financed collaboration model was carried out. Although research has shown positive results from co-financed collaboration on staff and organization, we could not find that this new interdisciplinary team structure gave a better patient health outcome than conventional care.

Social aggregation and lateralised response to social stimuli in tadpoles (Bufo bufo): influence of developmental stage.

In previous studies several species of tadpoles showed a preference for using the left hemifield when approaching a conspecific and during fixation of their own mirror images. These lateral biases typically emerge 5 minutes after the placement of the animals in the test apparatus possibly due to variation in tadpoles' social propensity during the test. The aim of this study is to check whether lateralised response to social stimuli in tadpoles varies during their development. I compared tadpoles of three age classes from a few days after emergence from eggs to close to metamorphosis. In accordance with previous studies I found that tadpoles displayed a preference for the left hemifield when approaching a conspecific and that the bias emerged 5 minutes after placement in the test apparatus. No marked change with development was observed, yet the degree of laterality tended to decrease with age and tadpoles of intermediate age showed left-hemifield dominance during the test significantly earlier than the other two groups.

Protecting children from chemical exposure: social work and U.S. social welfare policy.

Evidence suggests that the combinations of over 70,000 to 75,000 chemicals in air, land, water, and food to which children are exposed daily are instrumental in increasing the rates and severity of preventable childhood illness from asthma, leukemia, and other diseases. This article defines chemical contamination and reviews data regarding the ubiquity of toxic chemicals in the United States. It describes major risk pathways to fetuses and children at different developmental stages and discusses evidence regarding exposure and harm to children from chemical contamination. The adequacy of national social welfare and environmental policies is assessed and policy-level interventions are recommended to address the unique vulnerability of children--especially children who are poor and children of color-to toxic chemicals. The authors review the roles for social workers in protecting current and future generations from environmental contaminants.

On the relation between social information processing and socially competent behavior in early school-aged children.

This article tested the hypotheses that (1) children's behavioral competence is a function of patterns of social information processing; (2) processing correlates of behavior occur at each of 5 steps of processing within each of 3 social situations; (3) measures at each step uniquely increment each other in predicting behavior; (4) the relation between processing and behavior is stronger within than across domains; and (5) processing patterns are more sophisticated among older than younger children and the processing-behavior relation is stronger among older than younger children. Videorecorded stimuli were used to assess processing patterns (encoding, interpretational errors and bias, response generation, response evaluation, and enactment skill) in 3 domains (peer group entry, response to provocation, and response to authority directive) in 259 first-, second-, and third-grade boys and girls (ages 6-9 years). Ratings of behavioral competence in each domain were made by peers and teachers. Findings generally supported hypotheses, with the magnitude of relations being modest.

Becoming a social partner with peers: cooperation and social understanding in one- and two-year-olds.

One- and two-year-old peer dyads were presented with a simple cooperative task. Age differences were found in amount of coordinated activity, monitoring the peer's activity and location in relation to the goal, and attempting to achieve the goal when the peer was (or was not) available as a partner. One-year-olds' coordinated actions appeared more coincidental than cooperative whereas older children appeared to be more actively cooperating toward a shared goal. Differences in coordinated activity with peers were associated with differences in attention sharing with an adult and with language about self and other. The ability to cooperate with peers, becoming a true social partner, develops over the 2nd and 3rd years of life in concert with growing social understanding.

The medicalisation of shyness: from social misfits to social fitness.

Shyness has become an 'unhealthy' state of mind for individuals living in contemporary Western societies. Insofar as its behavioural 'symptoms' imply a failure to achieve certain cultural values, such as assertiveness, self-expression and loquacious vocality, shyness is increasingly defined as a problem for which people can, and should, be treated. This paper first critically discusses the idea that we are witnessing a new 'cultural epidemic' of shyness, as evidenced by increasing rates of diagnosis for Social Phobia, Social Anxiety Disorder and Avoidant Personality Disorder. It then examines three main dimensions of the medicalisation of shyness: biomedical and genetic approaches, the therapeutic interventions of cognitive-behaviour therapy and 'shyness clinics', and the disciplinary regimes imposed by self-help books and websites. Within a cultural climate of pervasive anxiety and privatised risk, the medicalisation of shyness suggests a powerful new way of defining and managing certain kinds of deviant identities, but we can also find some evidence of resistance to this approach.

A model of preverbal social development and its application to social dysfunctions in autism.

Studies of early face perception are used to develop a model of how face expressions might be transduced to initiate consonant internal affect, related outward expressions and other behaviours. Underlying neural mechanisms and processes are identified. The model is generalised to offer an account of aspects of typical preverbal social development. It is then used to develop aetiological hypotheses about the lack of social interest and motivation in autism and to provide a framework for evaluating other theories of autism. Although derived from existing literature, the model offers a distinctive account.

The desk directory of social resources: a physicians' reference guide to social and community services for the aged.

Physicians not only have a responsibility for the diagnosis and management of illness in the aged but also must address the patient's emotional needs, functional status, and psychosocial problems. The Institute of Medicine Report on Geriatric Medical Education has emphasized the need to train physicians to understand how the social components of care enhance the course and outcome of treatment. A physician's reference guide to social and community services should be developed to provide information that will enable clinicians to integrate medical and community health services into their practice.
