The relationship between auditory processing and restricted, repetitive behaviors in adults with autism spectrum disorders

Current views suggest that autism spectrum disorders (ASDs) are characterised by enhanced low-level auditory discrimination abilities. Little is known, however, about whether enhanced abilities are universal in ASD and how they relate to symptomatology. We tested auditory discrimination for intensity, frequency and duration in 21 adults with ASD and 21 IQ and age-matched controls. Contrary to predictions, there were significant deficits in ASD on all acoustic parameters. The findings suggest that low-level auditory discrimination ability varies widely within ASD and this variability relates to IQ level, and influences the severity of restricted and repetitive behaviours (RRBs). We suggest that it is essential to further our understanding of the potential contributing role of sensory perception ability on the emergence of RRBs.

Proximity and gaze influences facial temperature: a thermal infrared imaging study.

Direct gaze and interpersonal proximity are known to lead to changes in psycho-physiology, behavior and brain function. We know little, however, about subtler facial reactions such as rise and fall in temperature, which may be sensitive to contextual effects and functional in social interactions. Using thermal infrared imaging cameras 18 female adult participants were filmed at two interpersonal distances (intimate and social) and two gaze conditions (averted and direct). The order of variation in distance was counterbalanced: half the participants experienced a female experimenters gaze at the social distance first before the intimate distance (a socially “normal” order) and half experienced the intimate distance first and then the social distance (an odd social order). At both distances averted gaze always preceded direct gaze. We found strong correlations in thermal changes between six areas of the face (forehead, chin, cheeks, nose, maxilliary, and periorbital regions) for all experimental conditions and developed a composite measure of thermal shifts for all analyses. Interpersonal proximity led to a thermal rise, but only in the “normal” social order. Direct gaze, compared to averted gaze, led to a thermal increase at both distances with a stronger effect at intimate distance, in both orders of distance variation. Participants reported direct gaze as more intrusive than averted gaze, especially at the intimate distance. These results demonstrate the powerful effects of another persons gaze on psycho-physiological responses, even at a distance and independent of context.

The Prevalence, Severity, and Impact of Breast Pain in the General Population

Breast pain has been investigated in clinical populations; however we have yet to understand the prevalence and severity of this condition in the general population to determine whether more should be done to minimize the impact of this condition on womens quality of life. Therefore, this study investigated the prevalence, severity, and impact of breast pain on quality of life and factors associated with breast pain in a normal population sample. 1,659 females (34.1 ± 13.2 years) completed the Breast Pain Questionnaire online, providing information on demographics, duration, frequency, and severity of breast pain, its association with the menstrual cycle, relieving, and aggravating factors and the impact on quality of life. Over half the sample (51.5%) experienced breast pain, with a severity similar to that reported in clinical populations. There was a higher prevalence of breast pain in older participants, larger breasted participants and those who were less fit and active. Of symptomatic participants, 41% and 35% reported breast pain affecting quality of life measures of sex and sleep and 10% of symptomatic participants had sufferer for over half their lives. The results of this study suggest that breast pain is a significant issue within the general population and yet this is the first study to investigate it. It is concluded that this condition warrants increased investigation, awareness, and treatment. The reported relationship between breast pain and fitness/activity levels may offer an alternative treatment in the form of exercise intervention strategies to reduce breast pain.

The "textbook Gibson":The assimilation of dissidence

We examine how the textbooks have dealt with one of psychologys most eminent dissidents, James Gibson (1904-1979). Our review of more than a hundred textbooks, dating from the 1950s to the present, reveals fundamental and systematic misrepresentations of Gibson. Although Gibson continues to figure in most of the textbooks, his work is routinely assimilated to theoretical positions he emphatically rejected: cue theory, stimulus-response psychology, and nativism. As Gibsons one-time colleague, Ulric Neisser, pointed out, psychologists are especially prone to trying to understand new proposals by mapping it on to some existing scheme, and warned that when an idea is really new, that strategy fails (Neisser, 1990, p. 749). The Textbook Gibson is an example of such a failure, and perhaps also of the more general importance of assimilation-shadow history-within the actual history of psychology.

Sympathy crying: insights from infrared thermal imaging on a female sample

Sympathy crying is an odd and complex mixture of physiological and emotional phenomena. Standard psychophysiological theories of emotion cannot attribute crying to a single subdivision of the autonomic nervous system (ANS) and disagreement exists regarding the emotional origin of sympathy crying. The current experiment examines sympathy crying using functional thermal infrared imaging (FTII), a novel contactless measure of ANS activity. To induce crying female participants were given the choice to decide which film they wanted to cry to. Compared to baseline, temperature started increasing on the forehead, the peri-orbital region, the cheeks and the chin before crying and reached even higher temperatures during crying. The maxillary area showed the opposite pattern and a gradual temperature decrease was observed compared to baseline as a result of emotional sweating. The results suggest that tears of sympathy are part of a complex autonomic interaction between the sympathetic and the parasympathetic nervous systems, with the latter preceding the former. The emotional origin of the phenomenon seems to derive from subjective internal factors that relate to one’s personal experiences and attributes with tears arising in the form of catharses or as part of shared sadness.

Police officers’ perceptions of interviews in cases of sexual offences and murder involving children and adult victims

This paper examines 90 UK police officers’ perceptions of characteristics of interviews with suspects of rape and murder involving child and adult victims. Officers rated their beliefs about how stressful they would find such interviews, the importance of confessions, their likely emotional involvement and how much empathy they would show towards the suspect. Murder cases were reported to be more stressful than rape, and confessions were deemed to be less important for respondents compared to ‘other’ officers. Officers reported that they would become more emotionally involved in cases involving children, and they would show more empathy in murder cases than rape cases. Officers were unable to provide clear and unambiguous definitions of ‘empathy’ or ‘sympathy’.

Addressing Criminality in Childhood: Is Responsivity the Central Issue?

The responsivity principle is the third element of the now well-established risk–need–responsivity (RNR) model of offender rehabilitation. Accruing evidence suggests it is often sacrificed in intervention programs. We aim to demonstrate the central importance of this principle when designing offender interventions by describing the results of a successful, highly responsive intervention for very young children (aged 7 upward) who have offended. A small slice of the offending population as a whole, child offenders are nevertheless tomorrow’s serious, violent, and prolific lawbreakers, yet little is understood about what reduces their risk. Recent developments on responsivity are reviewed, before presenting the evaluation indicating significant and sustained drops in risk of recidivism. In-program factors such as the nature and dosage of interventions are examined, alongside outcome data. The article discusses how RNR and other models might apply to this particularly young and underresearched age group.

Human attention affects facial expressions in domestic dogs

Most mammalian species produce facial expressions. Historically, animal facial expressions have been considered inflexible and involuntary displays of emotional states rather than active attempts to communicate with others. In the current study, we aimed to test whether domestic dog facial expressions are subject to audience effects and/ or changes in response to an arousing stimulus (e.g. food) alone. We presented dogs with an experimental situation in which a human demonstrator was either attending to them or turned away, and varied whether she presented food or not. Dogs produced significantly more facial movements when the human was attentive than when she was not. The food, however, as a non-social but arousing stimulus, did not affect the dogs’ behaviour. The current study is therefore evidence that dogs are sensitive to the human’s attentional state when producing facial expressions, suggesting that facial expressions are not just inflexible and involuntary displays of emotional states, but rather potentially active attempts to communicate with others.

Evidence of big five and aggressive personalities in gait biomechanics

Behavioral observation techniques which relate action to personality have long been neglected (Furr and Funder in Handbook of research methods in personality psychology, The Guilford Press, New York, 2007) and, when employed, often use human judges to code behavior. In the current study we used an alternative to human coding (biomechanical research techniques) to investigate how personality traits are manifest in gait. We used motion capture technology to record 29 participants walking on a treadmill at their natural speed. We analyzed their thorax and pelvis movements, as well as speed of gait. Participants completed personality questionnaires, including a Big Five measure and a trait aggression questionnaire. We found that gait related to several of our personality measures. The magnitude of upper body movement, lower body movement, and walking speed, were related to Big Five personality traits and aggression. Here, we present evidence that some gait measures can relate to Big Five and aggressive personalities. We know of no other examples of research where gait has been shown to correlate with self-reported measures of personality and suggest that more research should be conducted between largely automatic movement and personality.

The Impact of Question Type and Empathy on Police Interviews with Suspects of Homicide, Filicide and Child Sexual Abuse

Conducting interviews with “high-stake” offenders, especially those accused of murder and sexual offences, represents a complex and emotive area of work for police officers. Using an English sample of 59 actual police interviews, the effects of empathy and question type on the amount of investigation-relevant information obtained from interviews with suspects of child murder, child sex offences and adult murder were analysed and compared. No direct effects of empathy on the amount of information elicited were found. However, in interviews classified as empathic, interviewers asked significantly more appropriate questions than they did in interviews classified as non-empathic, and significantly more items of information were elicited from appropriate questions. There was a significant effect of offence type on the number of inappropriate, questions asked, with significantly more inappropriate questions being asked in interviews with suspects of child sex offences than in interviews with suspects of child or adult murder.
