Effect of partial occlusion on newborns' face preference and recognition

Many studies have shown that newborns prefer (e.g. Goren, Sarty & Wu, 1975; Valenza, Simion, Macchi Cassia & Umiltà, 1996) and recognize (e.g. Bushnell, Say & Mullin, 1989; Pascalis & de Schonen, 1994) faces. However, it is not known whether, at birth, faces are still preferred and recognized when some of their parts are not visible because hindered by other configurations, that is when faces are partly occluded. Also, it is not known whether newborns' preference for an upright over an inverted face and newborns' face recognition are differentially affected depending on the salience of the occluded face features. Seventy-seven newborns (mean age of 43.5 hrs) were tested using the preferential looking (Experiment 1) and the habituation techniques (Experiment 2). Results demonstrated that newborns prefer and recognize occluded faces even if some portions of them are not available, at least when the hindered features are not salient. On the contrary, these abilities are affected by obscuring high salience facial features (i.e. eyes). However, while in the case of face detection, eyes occlusion completely prevented newborns' face detection, in the case of face recognition an analogous stimulus manipulation heavily impaired, but did not totally preclude, newborns' recognition performance. The data collected improve our comprehension of newborns' way of processing and encoding information to detect and recognize faces.     

Aging and the intrusion superiority effect in visuo-spatial working memory

This study investigated the active component of visuo-spatial working memory (VSWM) in younger and older adults testing the hypotheses that elderly individuals have a poorer performance than younger ones and that errors in active VSWM tasks depend, at least partially, on difficulties in avoiding intrusions (i.e., avoiding already activated information). In two experiments, participants were presented with sequences of matrices on which three positions were pointed out sequentially: their task was to process all the positions but indicate only the final position of each sequence. Results showed a poorer performance in the elderly compared to the younger group and a higher number of intrusion (errors due to activated but irrelevant positions) rather than invention (errors consisting of pointing out a position never indicated by the experiementer) errors. The number of errors increased when a concurrent task was introduced (Experiment 1) and it was affected by different patterns of matrices (Experiment 2). In general, results show that elderly people have an impaired VSWM and produce a large number of errors due to inhibition failures. However, both the younger and the older adults' visuo-spatial working memory was affected by the presence of activated irrelevant information, the reduction of the available resources, and task constraints.     

Lack of strategy holding: A new pattern of learning deficit in cortical dementias

The aim of this study was to demonstrate, by means of systematic research and qualitative data analysis, the presence, among a group of patients with fronto‐temporal lobar degeneration of a subgroup that, at variance with the standard pattern, is able to devise and implement learning strategies, but appear impaired at carrying them on from a trial to the next. In order to provide evidence of the existence of a group of patients showing this type of learning disability, that we refer to as lack of strategy holding, we performed a stepwise hierarchical cluster analysis of a set of variables whose scores were selected from the subject's performance at the Test de Aprendizaje Verbal España‐Complutense. Results substantiate the segregation of three groups of subjects characterized by the following patterns of performance: normal elderly individuals, who show a quite preserved ability to discover a semantic strategy along the learning trials and to carry it from a trial to the next, patients presenting with a deficit in implementing semantic learning strategies and possibly use of serial and/or phonological strategies to perform the task, and to patients who, although able to generate and implement appropriate learning strategies, appear unable to carry them over the learning trials. The presence of this new pattern raises a few questions that seem worth trying to address.     

Group identification and self-efficacy associated with quality of life in emergency medical services volunteers: A cross-sectional investigation

Volunteering in emergency medical services (EMS) plays a fundamental role in the improvement and maintenance of collective and community health. However, this work often requires rescuers to deal with very stressful situations with consequences in terms of decreased quality of life and psychological well-being. The aim of this work was to analyze the resources that can be positively associated with volunteers’ quality of life. In particular, based on social identity and social cure approaches, we tested the effect of self-efficacy and identification with a volunteer category on both positive and negative aspects of the volunteers’ professional quality of life. A self-report questionnaire was administered to 203 EMS volunteers (53.7% men) from a large nonprofit volunteer association. Results are mostly supportive of predictions from the social identity (and specifically the “social cure”) approach, and show that professional identification and self-efficacy were differently linked to the dimensions of the volunteers’ quality of life. More precisely, professional identification was negatively associated with burnout and positively associated with compassion satisfaction, and both effects were mediated by self-efficacy. On the contrary, self-efficacy and volunteer identification were not associated with secondary traumatic stress. Practical implications for volunteers’ wellbeing are discussed in the light of the policies of volunteer associations to improve collective resources.     

Clinician-Guided Assessment of Personality Using the Structural Interview and the Structured Interview of Personality Organization (STIPO)

This article demonstrates the utility of a theory-guided psychodynamic approach to the assessment of personality and personality pathology based on the object relations model developed by Kernberg (1984). We describe a clinical interview, the Structural Interview (SI; Kernberg, 1984), and also a semistructured approach, the Structured Interview of Personality Organization (STIPO; Clarkin, Caligor, Stern, & Kernberg, 2004) based on this theoretical model. Both interviews focus on the assessment of consolidated identity versus identity disturbance, the use of adaptive versus lower level defensive operations, and intact versus loss of reality testing. In the context of a more clinically oriented assessment, the SI makes use of tactful confrontation of discrepancies and contradictions in the patient's narrative, and also takes into account transference and countertransference phenomena, whereas the more structured approach of the STIPO incorporates clinical judgment informed by clinical theory into a well-guided interaction with the patient. Both interviews have good interrater reliability and are coherent with the alternative model for personality disorder diagnosis proposed by the Diagnostic and Statistical Manual of Mental Disorders (5th ed.), Section III. Finally, they provide the clinician with specific implications for prognosis and treatment planning and can rationally guide clinical decision making.
