Man,You Might Look Like a Woman—If a Child Is Next to You

Gender categorization seems prone to a pervasive bias: Persons about whom null or ambiguous gender information is available are more often considered male than female. Our study assessed whether such a male-bias is present in non-binary choice tasks and whether it can be altered by social contextual information. Participants were asked to report their perception of an adult figure’s gender in three context conditions: (1) alone, (2) passively besides a child, or (3) actively helping a child (n = 10 pictures each). The response options male, female and I don’t know were provided. As a result, participants attributed male gender to most figures and rarely used the I don’t know option in all conditions, but were more likely to attribute female gender to the same adult figure if it was shown with a child. If such social contextual information was provided in the first rather than the second block of the experiment, subsequent female gender attributions increased for adult figures shown alone. Additionally, female gender attributions for actively helping relative to passive adults were made more often. Thus, we provide strong evidence that gender categorization can be altered by social context even if the subject of gender categorization remains identical.     

Connections between Family Centered Care and Medical Homes of Children with Neurodevelopmental Disabilities: Experiences of Diverse Families

Cultural issues tied to race/ethnicity are important aspects in delivering medical home services to children with neurodevelopmental disabilities and their families. To better understand family satisfaction with family centered care (FCC) in medical homes of children with disabilities, this study investigated whether family race/ethnicity, in addition to parent and child characteristics, significantly influenced family perceptions of FCC in three areas: family-provider partnership, care setting practices and policies, and community coordination and follow-up. Based on the life course theory for optimizing children's developmental trajectories, examining connections between family race/ethnicity and satisfaction with health care allows for identification of strengths and weaknesses in medical home services delivery, and offers opportunities for family support and improvement in outcomes for children with disabilities. This study developed an original empirical survey using a structured questionnaire developed by Family Voices, a national advocacy organization dedicated to promoting the well-being of children with disabilities and their families. The study collected data for 122 families in a large urban area in the northeastern United States. Multivariate analyses revealed that family race/ethnicity significantly contributed to the prediction of parental satisfaction with medical homes of children with disabilities, and to families' perceptions of FCC in care setting practices and policies, and community coordination and followup, but not to family provider partnership. Non-White families reported significantly lower satisfaction. Discussion emphasizes that health care providers need to become more vigilant in providing culturally sensitive care. To enhance FCC practices and policies, the study advances a checklist of ten essential areas that promote culturally sensitive interactions between families of children with disabilities and their medical and non-medical health care providers.     

Words and Drugs: Same Mechanisms of Action?

The therapeutic effects of words, rituals and, more in general, of the whole psychosocial context around the patient, have been investigated over the past few years by using the placebo response as a model. Today we are in a good position to study all these complex psychological factors by using a physiological and neuroscientific approach that uses modern neurobiological tools to probe different brain functions. Since a placebo is represented by the whole ritual of the therapeutic act, the main concept that has emerged today is that words and rituals may modulate the same biochemical pathways that are modulated by drugs. Most of our knowledge about these mechanisms comes from the field of pain, and represents a biomedical, psychological and philosophical enterprise that is changing the way we approach and interpret medicine, psychology and human biology. If on the one hand we know some of the mechanisms of drug action in the central nervous system, on the other we can now understand how the therapist’s words may affect different physiological functions. In fact, the placebo effect and the therapist–patient relationship can be approached by using the same biochemical, cellular and physiological tools of the materia medica. Although the responses to the therapist’s words cannot be reduced merely to the action of a single drug, this represents an epochal transition, in which the distinction between psychotherapy and pharmacotherapy is progressively getting thinner, and which helps us overcome the old dichotomy between psychology and biology.     

Motor imagery effectiveness for mirror reversed movements

Physical practice is known to enhance motor adaptation skills, which refer to the individual ability to compensate for environmental changes. So far, it is still unknown whether a similar effect can be observed following motor imagery (MI). Thirty-nine participants were tested during a joystick tracking task under both normal and mirror conditions (i.e., the inductive direction of the joystick was reversed), before and after a physical practice or MI training phase. Eye movements and electromyographic activity were recorded during MI. Motor performance was also evaluated after a 6 h interval during daytime. As compared to the control group, the results revealed that both MI and physical practice improved motor performance in the mirror condition, during the post-training test. Furthermore, the time to complete the task was further reduced after 6 hours, both in the normal and mirror conditions. These results demonstrate the effectiveness of MI for learning mirror-reversed movements, and for the consolidation process that follows motor adaptation.     

Localization of tactile stimuli and body parts in space: two dissociated perceptual experiences revealed by a lack of constancy in the presence of position sense and motor activity

Two motor acts were analyzed at the level of tongue and fingers. These motor acts generated illusions. When subjects voluntarily rotated the tongue by 90 degrees, the perceived orientation of a tactile stimulus applied to the tongue did not covary with the perceived orientation of the tongue itself. Analogously, when subjects voluntarily crossed two adjacent fingers, the perceived position of two tactile stimuli applied to the fingers did not covary with the perceived position of the fingers themselves. Although tongue and fingers were positioned accurately in space, a lack of perceptual constancy occurred for tactile stimuli applied to these body parts. Therefore, whereas position sense was preserved, correct localization of objects was lost. The occurrence of this perceptual dissociation suggests that spatial localization of tactile stimuli may be independent both of knowledge of body part location and motor activity.     

On the mean and variance of the tetrachoric correlation coefficient

Estimates of the mean and standard deviation of the tetrachoric correlation are compared with their expected values in several 2 × 2 tables. Significant bias in the mean is found when the minimum cell frequency is less than 5. Three formulas for the standard deviation are compared and guidelines given for their use.This research was performed when the first author was on leave at the University of California at Los Angeles and was supported in part by NIH Special Research Resources Grant RR-3. The second author was also supported by NIH Fellowship 5 F22 GM00328-02.     

The effects of phonological similarity on the semantic categorisation of pictorial and lexical stimuli: evidence from continuous behavioural measures

Behavioural and neuroimaging studies provide evidence of automatic activation of phonology (e.g., covert speech) during the recognition of lexical stimuli. Implicit processing of phonological information was investigated in a kinematic study of semantic categorisation of pictures (session A) or words (session B). Participants clicked one of two items (target and distractor) based on their semantic congruency (artefact or natural) with a cued-word. Phonological similarity between cued-word and distractor was varied. The presence of the phonological distractor produced trajectories with greater curvature towards the competing semantic category than did the presence of a distractor not phonologically related. This suggests that the semantic categorisation of pictorial and lexical stimuli is influenced by the automatic activation of phonological information. Trajectories’ curvature reveals competition between partially activated phonological and semantic representations suggesting that phonological codes involved in linguistic processing influence the dynamic competition underlying the semantic categorisation of lexical and pictorial.

Abstract

The profound psychic differences between the two human sexes are also reflected in their diverse psychopathology, even though the basic clinical forms remain common for both. In this study the problem of the psychoanalytic difference between the two sexes is discussed within the framework of psychotic situations; in intrapsychic relationships with the mother and the father, and between the patient and the therapist and with his sex. The problem of masculine and feminine psychosexuality is furthermore seen in a different light, in accordance with its pre- or postoedipal configuration.     

Processing of tactile spatial information with crossed fingers

The erroneous perception of two objects when one object is touched with crossed fingers has been explained as an inability of the brain to correctly perceive the crossed fingers' positions. This account is examined in Experiment 1, in which the perceived position of stimuli touching the crossed fingers is mapped. Crossing the third finger over the fourth displaced the perceived stimulus position counter-clockwise; crossing the third under the fourth displaced perceptions clockwise. In Experiment 2, perceived positions were found to fit a model of tactile saturation past the point of the functional range of action of the fingers. Two major conclusions are drawn: (a) Tactile stimuli are always perceived as if fingers were uncrossed, and (b) spatial mapping is present only within the functional range of finger excursion.     

A comparison of auditory monitoring performance in blind subjects with that of sighted subjects in light and dark

Two experiments were performed in which blind Ss, sighted Ss working in the dark, and sighted Ss working in the light were compared as to their efficiency on an auditory watchkeeping task. Absolute and differential auditory thresholds were measured in both experiments, and in the second experiment the groups also underwent a signal detection session under alerted conditions. There was some inconsistency as to relative performance of the sighted groups, but in both experiments the blind Ss were superior on the auditory watchkeeping task as to signals detected and effective sensitivity (d’). 1 This difference was not attributable to a difference in auditory sensitivity or to a criterion adopted for
